Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more particularly to a steam cooking appliance. Background Technology

[0002] With the popularization of healthy eating concepts and the improvement of living standards, steaming and boiling have gradually become the mainstream cooking methods in many households, and steam cooking appliances have gradually become indispensable kitchen appliances in modern homes. Traditional steam cooking appliances usually include a main unit, a drip tray, and a steaming basket. The main unit has a water storage chamber, the drip tray is placed on the main unit, and the steaming basket is placed on the drip tray. The steam generated in the water storage chamber is used to steam the food in the steaming basket.

[0003] To facilitate adding water to the main unit's water reservoir without removing the steamer basket, related technologies, such as the patent with publication number CN 222055181U, propose setting a water replenishment tank on the base, which is connected to the water storage tank on the base. Adding water to the replenishment tank replenishes the water storage tank, preventing the steam cooking appliance from drying out. However, because the base has both a water storage tank and a water replenishment tank, when emptying the water after use, a water collection area appears in both tanks. Users need to consider the water flow paths in both areas, resulting in a poor emptying experience.

[0004] To address the aforementioned technical issues, the researchers of this application considered incorporating an integrated water cavity into the main unit and a downward-extending partition plate on the drip tray. When the drip tray is installed, the partition plate divides the water cavity into a main water cavity and a secondary water cavity, allowing users to add water to the main water cavity via the secondary cavity. When the drip tray is removed, the secondary water cavity disappears, facilitating the user's emptying of the water. However, due to assembly tolerances, to ensure the partition plate is properly inserted into the main unit's water cavity, an unavoidable assembly gap exists between the vertical edges of the partition plate and the inner wall of the main unit. Even when the lower side of the partition plate is sealed to prevent air leakage, gaps still exist between the vertical edges of the partition plate and the inner wall of the main unit when water is present in the water cavity. Consequently, steam leakage occurs during cooking, causing steam generated in the main water cavity to overflow and resulting in significant heat loss. Utility Model Content

[0005] To address the issues of poor user experience when pouring water and heat loss due to steam overflow, this application provides a steam cooking appliance that combines a good user experience when pouring water with reduced steam overflow.

[0006] This application provides a steam cooking appliance, including a main unit and a drip tray. The main unit has an integrated water cavity, and the drip tray has a downwardly extending partition plate. A first mating part is formed at each of the two vertical edges of the partition plate. A second mating part corresponding to the first mating part is formed on the inner side wall of the main unit. The drip tray is placed on the main unit, and the partition plate is inserted into the water cavity. The first mating part and the second mating part abut or insert into each other. The partition plate divides the water cavity into a main water cavity and a secondary water cavity that are connected. The main water cavity is located below the drip tray, and the secondary water cavity is located on one side of the drip tray to form a water filling cavity.

[0007] In some embodiments, the two vertical edges of the partition plate are respectively formed with abutment surfaces extending downwardly from the lower surface of the juice receiving tray, and the inner sidewall of the main unit is formed with a support step extending downwardly from the opening edge of the water cavity. The abutment surfaces form the first mating part, the support steps form the second mating part, and the abutment surfaces abut against the support steps.

[0008] In some embodiments, a notch is formed on the inner wall of the main water cavity, which sinks down from the opening of the water cavity, and a support step is formed at the bottom of the notch. The support step gradually extends in an inclined direction towards the secondary water cavity in a downward direction.

[0009] In some embodiments, the supporting steps are formed on the two opposite inner walls of the main water cavity; The partition plate includes a main body and a side panel. The main body divides the water cavity into the main water cavity and the secondary water cavity. The two ends of the main body are bent and extended in a direction away from the secondary water cavity to form the side panel. The edge of each side panel away from the main body forms the contact surface.

[0010] In some embodiments, the auxiliary water cavity is located at one corner of the main water cavity, a communication port connecting the main water cavity and the auxiliary water cavity is formed between two adjacent inner sidewalls of the main water cavity, and the supporting steps are respectively formed on the two adjacent inner sidewalls of the main water cavity; The partition plate includes a main body and a side enclosure. The main body is disposed at the communication opening. One end of the main body is bent and extended in a direction away from the secondary water cavity to form the side enclosure. The side edge of the main body away from the side enclosure and the side edge of the side enclosure away from the main body respectively form the contact surface.

[0011] In some embodiments, an inlet is formed between the lower end face of the partition plate and the bottom face of the secondary water cavity, and the support step extends downward from the opening edge of the water cavity to the upper edge of the inlet.

[0012] In some embodiments, vertically extending insertion ribs are formed at the vertical edges on both sides of the partition plate, and an insertion groove extending vertically downward from the opening edge of the water cavity is formed on the inner side wall of the main unit. The insertion ribs form the first mating part, the insertion grooves form the second mating part, and the insertion ribs are inserted into the insertion grooves.

[0013] In some embodiments, the bottom of the secondary water cavity is provided with a boss, the top surface of the boss forms the bottom surface of the secondary water cavity, and the bottom surface of the secondary water cavity is higher than the bottom surface of the main water cavity; The partition plate is inserted on one side of the boss, and at least a portion of the lower end face of the partition plate is lower than the height of the top face of the boss.

[0014] In some embodiments, a ramp is formed on the boss, at least a portion of the surface of the ramp being lower than the height of the lower end face of the partition plate, and forming an inlet between the ramp and the lower end face of the partition plate.

[0015] In some embodiments, the bottom of the juice receiving tray is provided with a downwardly extending energy-concentrating ring rib, and the bottom surface of the water cavity is provided with an upwardly extending surrounding rib. The energy-concentrating ring rib and the surrounding rib are interlocked to form a steam cavity, and the lowest downward extension height of the partition plate does not exceed the lowest downward extension height of the energy-concentrating ring rib.

[0016] The technical solution provided in this application has at least the following advantages compared with the prior art: 1. The steam cooking appliance provided in this application features an integrated water cavity on the main unit, with a downward-extending partition plate on the drip tray. When the drip tray is installed, the partition plate divides the main unit's water cavity into a main water cavity and a secondary water cavity. The secondary water cavity, located to one side of the drip tray, forms a water filling chamber, allowing users to replenish water to the main water cavity by adding water to the secondary water cavity, thus preventing the steam cooking appliance from dry-burning. When the drip tray is removed, the secondary water cavity disappears, meaning the partition plate's function of separating the main unit's water cavity is eliminated. The main unit's water cavity then becomes a single, unified water cavity. This ensures that when users empty the water after use, only a single water collection area appears, providing convenience for the user. The water pouring operation is improved, enhancing the pouring experience. Furthermore, a first mating part is formed on each of the vertical edges of the partition plate, and a second mating part corresponding to the first mating part is formed on the inner wall of the main unit. When the drip tray is installed, the first mating part abuts or inserts into the corresponding second mating part to block the steam, thus creating a barrier in the steam's outward flow path. This minimizes the leakage of steam generated in the main water chamber through the gap between the vertical edges of the partition plate and the inner wall of the main unit, thereby reducing heat loss. This allows the steam cooking appliance of this application to combine a better user experience in pouring water with reduced steam leakage.

[0017] 2. By forming abutment surfaces extending downward from the lower surface of the drip tray at both vertical edges of the partition plate, and a support step extending downward from the opening of the water chamber on the inner wall of the main unit, a sealing effect is achieved through the abutment surfaces of the partition plate and the support steps of the main unit. Since the abutment surfaces extend downward from the lower surface of the drip tray and the support steps extend downward from the opening of the water chamber, the continuity of the abutment seal is ensured. This allows the abutment surfaces and the support steps to form an effective abutment seal in the height direction of the water chamber, thereby effectively preventing steam generated in the main water chamber from overflowing outward between the two vertical edges of the partition plate and the inner wall of the main unit, reducing heat loss.

[0018] 3. By forming a notch that sinks down from the edge of the water cavity on the inner wall of the main water cavity, and forming a support step at the bottom of the notch, the support step is easy to process and has high structural strength. Furthermore, by setting the support step on the inner wall of the main water cavity and gradually extending towards the secondary water cavity from top to bottom, the abutting surface of the partition plate can smoothly abut against the support step on the inner wall of the main water cavity.

[0019] 4. By setting support steps on the two opposite inner walls of the main water chamber, the two opposite side panels of the partition plate abut against the two opposite inner walls of the main water chamber to form a seal. In this structure, the auxiliary water chamber can be set on one side of the main water chamber, and the width of the auxiliary water chamber can be equal to the width of the main water chamber along the direction perpendicular to the two opposite inner walls of the main water chamber, so that the auxiliary water chamber has a larger width, making it convenient for users to add water to the auxiliary water chamber.

[0020] 5. By setting the auxiliary water chamber to one corner of the main water chamber, the width of the auxiliary water chamber is smaller than the width of the main water chamber in the direction perpendicular to the two opposite inner walls of the main water chamber. This reduces the space occupied by the auxiliary water chamber on the main unit, so that more space can be left on the main unit to arrange other structures.

[0021] 6. An inlet is formed between the lower end face of the partition plate and the bottom face of the auxiliary water chamber, allowing water from the auxiliary water chamber to enter the main water chamber through the inlet. A support step is provided that slopes downward from the edge of the water chamber to the upper edge of the inlet to ensure the continuity of the sealing between the contact surface and the support step, thus better reducing the risk of steam overflow. When the water level in the main water chamber is higher than the upper edge of the inlet, a water seal can be formed. Thus, the contact between the vertical edges of the partition plate on both sides and the inner wall of the main unit, combined with the water seal, achieves a good effect of preventing steam overflow.

[0022] 7. By forming vertically extending insertion ribs on both sides of the partition plate and forming insertion grooves extending vertically downward from the water chamber opening on the inner wall of the main unit, the insertion ribs and insertion grooves are connected to increase the flow path length of steam in the main water chamber when it overflows through the gap between the insertion ribs and insertion grooves, thereby reducing steam overflow.

[0023] 8. By providing a boss at the bottom of the auxiliary water chamber, when the juice receiving tray is placed on the main unit, the partition plate is inserted on one side of the boss, so as to use the boss to limit the partition plate and limit the partition plate to one side of the boss, thereby limiting the juice receiving tray to the upper area of ​​the main water chamber.

[0024] 9. By forming a ramp on the boss, an inlet is formed between the surface of the ramp and the lower end face of the partition plate, ensuring that the water in the auxiliary water chamber flows smoothly into the main water chamber through the inlet.

[0025] 10. By setting the minimum height of the downward extension of the partition plate to not exceed the minimum height of the downward extension of the energy-concentrating ring rib, the energy-concentrating ring rib can be supported on the placement surface when the juice tray is placed on a table or other placement surface, so that the juice tray can be placed flat on the table or other placement surface.

[0030] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0032] Reference Figures 1 to 10 As shown, some embodiments of this application provide a steam cooking appliance, including a main unit 1 and a drip tray 2.

[0033] The main unit 1 has an integrated water cavity 100. The juice receiving tray 2 is provided with a downwardly extending partition plate 21. The vertical edges on both sides of the partition plate 21 are respectively formed with first mating parts. The inner side wall of the main unit 1 is formed with a second mating part corresponding to the first mating part. The juice receiving tray 2 is placed on the main unit 1. The partition plate 21 is inserted into the water cavity 100. The first mating part and the second mating part abut or insert into each other. The partition plate 21 divides the water cavity 100 into a connected main water cavity 101 and a secondary water cavity 102. The main water cavity 101 is located below the juice receiving tray 2. The secondary water cavity 102 is located on one side of the juice receiving tray 2 to form a water filling cavity.

[0034] It should be understood that the main unit 1 has an integrated water cavity 100, meaning that the water cavity 100 on the main unit 1 is a single unit, specifically formed by the bottom wall and side walls of the main unit 1; rather than two or more separate water cavities separated by partitions, nor two or more independently set water cavity structures. This integrated water cavity 100 allows only one water collection area to be formed in the water cavity 100 when the user pours out the water, making it convenient for the user to pour out the water in the water cavity 100.

[0035] The juice receiving tray 2 is provided with a downwardly extending partition plate 21. When the juice receiving tray 2 is placed on the main unit 1, the partition plate 21 on the juice receiving tray 2 is inserted into the water cavity 100 of the main unit 1, so as to divide the water cavity 100 of the main unit 1 into a connected main water cavity 101 and a secondary water cavity 102 by means of the partition plate 21. The main water cavity 101 is located below the juice receiving tray 2, and the secondary water cavity 102 is located on one side of the juice receiving tray 2 to form a water filling cavity. Thus, when the drip tray 2 is installed, the partition plate 21 on the drip tray 2 divides the water cavity 100 of the main unit 1 into a main water cavity 101 and a secondary water cavity 102. The secondary water cavity 102 is located on one side of the drip tray 2, forming a water filling cavity. This allows the user to add water to the secondary water cavity 102, and the water in the secondary water cavity 102 flows into the main water cavity 101, thus replenishing the main water cavity 101 and preventing the steam cooking appliance from dry burning. When the drip tray 2 is removed, the secondary water cavity 102 disappears. That is, after the partition plate 21 is removed from the water cavity 100 of the main unit 1, the water cavity 100 of the main unit 1 is formed as a whole water cavity. In this way, when the user pours out the water after use, only one water collection area will appear in the water cavity 100 of the main unit 1, which is convenient for the user to pour out the water and improves the water pouring experience.

[0036] For example, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the water cavity 100 on the main unit 1 can be a rectangular water cavity, and the width of the water cavity 100 is greater than the width of the juice receiving tray 2. The juice receiving tray 2 has a downwardly extending partition plate 21 on one side along its width direction. (Refer to...) Figure 1 and Figure 6 The direction indicated by arrow a in the diagram represents the width direction of the water cavity 100 and also the width direction of the juice tray 2. Thus, when the juice tray 2 is placed on the main unit 1, the partition plate 21 on the juice tray 2 is inserted into the water cavity 100 of the main unit 1, dividing the water cavity 100 of the main unit 1 into a main water cavity 101 located below the juice tray 2 and a secondary water cavity 102 located on one side of the juice tray 2.

[0037] Of course, in specific implementations, the water cavity 100 on the host 1 is not limited to a rectangular water cavity 100, but can also be a circular water cavity or a water cavity of other shapes, and no specific limitation is made here.

[0038] It should be noted that the divider 21 extends downward relative to the main plate of the drip tray 2. To achieve the function of dividing the water cavity 100 of the main unit 1, the divider 21 needs to have a certain width along the direction perpendicular to its downward extension, that is, the divider 21 needs to have a certain lateral width. The two sides of the divider 21, which are laterally separated, form the two vertical edges of the divider 21. In order to smoothly insert the divider 21 into the water cavity 100 of the main unit 1, there will inevitably be an assembly gap between the two vertical edges of the divider 21 and the inner wall of the main unit 1. That is to say, the two vertical edges of the divider 21 cannot be completely fitted vertically with the inner wall of the main unit 1, which will lead to assembly difficulties. However, the existence of this assembly gap leads to the problem of steam leakage during cooking, causing the steam generated in the main water cavity 101 to overflow and resulting in a large heat loss.

[0039] Based on this, the steam cooking appliance provided in this application has a first mating part formed on both sides of the vertical edge of the partition plate 21, and a second mating part corresponding to the first mating part formed on the inner wall of the main unit 1. When the drip tray 2 is installed, the first mating part and the corresponding second mating part abut or insert into each other to achieve the effect of blocking the steam, that is, forming a barrier on the flow path of the steam overflowing outward, thereby minimizing the overflow of steam generated in the main water chamber 101 through the vertical edge of both sides of the partition plate 21 and the inner wall of the main unit 1, thereby reducing heat loss. With this setting, the steam cooking appliance of this application has both a good user experience when pouring water and the effect of reducing steam overflow.

[0040] In some embodiments, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a water level scale 15 is provided on the inner wall of the secondary water chamber 102. This arrangement allows the user to monitor the water level in the water chamber 100 via the water level scale 15 on the inner wall of the secondary water chamber 102. Furthermore, since the water chamber 100 of the main unit 1 is an integrated water chamber, when the juice tray 2 is removed, the main water chamber 101 and the secondary water chamber 102 form an integrated water chamber. Therefore, it is only necessary to provide the water level scale 15 on the inner wall of the secondary water chamber 102, without having to provide the water level scale 15 on the inner wall of the main water chamber 101. This eliminates the redundant design of repeatedly setting the water level scale 15, simplifying the product design and reducing production costs.

[0041] In some embodiments, refer to Figure 2 and Figure 7As shown, a water inlet is formed at the top of the secondary water chamber 102, and a transparent cover 4 is provided at the water inlet. The transparent cover 4 is used to separate the space of the secondary water chamber 102 from the outside space, and at the same time, it allows the user to observe the water level in the secondary water chamber 102 through the transparent cover 4.

[0042] In addition, refer to Figure 1 and Figure 2 As shown, the steam cooking appliance also includes a steamer 3, which is positioned above the drip tray 2. The steam generated in the water chamber 100 of the main unit 1 can flow upward through the drip tray 2 to heat the food in the steamer 3.

[0043] It should be noted that, in specific implementations, a sealing seal can be formed by the abutting fit of the first and second mating parts to create a barrier on the flow path of steam overflowing outward in the main water chamber 101, thereby reducing steam overflow and heat loss; alternatively, the flow path length of steam overflowing outward through the insertion fit of the first and second mating parts can be increased to reduce steam overflow and heat loss.

[0044] In some embodiments, refer to Figure 3 and Figure 4 As shown, the two vertical edges of the partition plate 21 are respectively formed with abutment surfaces 211 extending downwardly from the lower surface of the drip tray 2, referring to... Figure 5 and Figure 6 As shown, a support step 11 is formed on the inner side wall of the main unit 1, which extends downward from the opening of the water cavity 100. The abutment surface 211 forms a first mating part, and the support step 11 forms a second mating part. The abutment surface 211 abuts and mates with the support step 11.

[0045] In the above embodiments, when the juice receiving tray 2 is placed on the main unit 1, the abutting surface 211 of the partition plate 21 abuts against the supporting step 11 of the main unit 1, thereby achieving a sealing effect through the abutting fit. Since the abutting surface 211 extends downward from the lower surface of the juice receiving tray 2 and the supporting step 11 extends downward from the opening edge of the water cavity 100, the continuity of the abutting seal is ensured, so that the abutting surface 211 and the supporting step 11 form an effective abutting seal in the height direction of the water cavity 100. This effectively prevents the steam generated in the main water cavity 101 from overflowing outward between the two vertical edges of the partition plate 21 and the inner wall of the main unit 1, reducing heat loss. Furthermore, this arrangement structure achieves the abutting seal between the partition plate 21 and the main unit 1 while the partition plate 21 is inserted into the water cavity 100. The structure is simple and easy to assemble.

[0046] In order to form a support step 11 on the inner wall of the host 1, in some embodiments, reference is made to... Figure 5 and Figure 6As shown, a notch 12 is formed on the inner wall of the main water cavity 101, which sinks down from the edge of the water cavity 100, and a support step 11 is formed at the bottom of the notch 12; the support step 11 gradually extends towards the secondary water cavity 102 in a downward direction.

[0047] In the above embodiment, by forming a notch 12 on the inner wall of the main water cavity 101 and forming a support step 11 at the bottom of the notch 12, the processing and forming of the support step 11 is more convenient, and the structural strength of the support step 11 is higher than that of the support step 11 which protrudes into the inner periphery of the main water cavity 101. Furthermore, by setting the support step 11 on the inner wall of the main water cavity 101 and gradually extending the support step 11 towards the secondary water cavity 102 in a downward direction, when the juice receiving tray 2 is placed on the main unit 1, the vertical edges on both sides of the partition plate 21 can smoothly abut against the corresponding support step 11 on the inner wall of the main water cavity 101.

[0048] In practical implementation, to ensure the stability of the mating fit between the contact surface 211 and the supporting step 11, refer to Figure 3 and Figure 4 As shown, the abutment surface 211 on the partition plate 21 includes a first abutment segment, a second abutment segment, and a third abutment segment that are smoothly connected in sequence. The slope of the second abutment segment relative to the horizontal plane is greater than the slopes of the first and third abutment segments relative to the horizontal plane. This results in the abutment surface 211 on the partition plate 21 forming a Z-shaped structure. Accordingly, referring to… Figure 5 and Figure 6 As shown, the support step 11 on the inner wall of the main unit 1 includes a first support segment, a second support segment, and a third support segment that are smoothly connected in sequence. The slope of the second support segment relative to the horizontal plane is greater than that of the first and third support segments relative to the horizontal plane. In this way, the support step 11 on the inner wall of the main unit 1 is formed as a Z-shaped structure.

[0049] In the above embodiments, the support step 11 and the abutment surface 211 are matched and configured. When the abutment surface 211 of the partition plate 21 abuts and cooperates with the support step 11 on the inner side wall of the host 1, it can be ensured that the first support section has a good supporting effect on the first abutment section and the third support section has a good supporting effect on the third abutment section, thereby ensuring that the abutment surface 211 and the support step 11 form a stable abutment cooperation effect.

[0050] Of course, in specific implementation, the shape of the contact surface 211 on the partition plate 21 and the supporting step 11 on the inner side wall of the host 1 is not limited to the above limitation, and can be reasonably set and adjusted according to the actual situation.

[0051] In some embodiments, refer to Figure 5 and Figure 6 As shown, support steps 11 are formed on the two opposite inner walls of the main water cavity 101; refer to Figure 3 and Figure 4 As shown, the partition plate 21 includes a main body 212 and a side wall 223. The main body 212 divides the water cavity 100 into a main water cavity 101 and a secondary water cavity 102. The two ends of the main body 212 are bent and extended in the direction away from the secondary water cavity 102 to form the side wall 223. The edge of each side wall 223 away from the main body 212 forms an abutment surface 211.

[0052] In the above embodiment, by providing supporting steps 11 on the two opposite inner walls of the main water cavity 101, the two opposite side portions 223 of the partition plate 21 abut against and cooperate with the two opposite inner walls of the main water cavity 101 to form a seal. In this structure, the auxiliary water cavity 102 can be provided on one side of the main water cavity 101, and along a direction perpendicular to the two opposite inner walls of the main water cavity 101 (e.g., Figure 6 (As indicated by arrow b in the diagram), the width of the secondary water chamber 102 can be equal to the width of the main water chamber 101, so that the secondary water chamber 102 has a larger width, making it convenient for users to add water to the secondary water chamber 102.

[0053] For example, refer to Figures 1 to 6 As shown, the water cavity 100 on the main unit 1 can be a rectangular water cavity, and the width of the water cavity 100 is greater than the width of the juice receiving tray 2. The juice receiving tray 2 has a downwardly extending partition plate 21 on one side along its width direction. (Refer to...) Figure 1 and Figure 6 The direction indicated by arrow 'a' in the diagram represents the width direction of the water cavity 100. Thus, when the juice tray 2 is placed on the main unit 1, the partition plate 21 on the juice tray 2 is inserted into the water cavity 100 of the main unit 1, dividing the water cavity 100 of the main unit 1 into a main water cavity 101 located below the juice tray 2 and a secondary water cavity 102 located on one side of the juice tray 2. Furthermore, along the direction perpendicular to the two opposite inner walls of the main water cavity 101 (e.g., ... Figure 6 (As indicated by arrow b in the diagram), the width of the secondary water chamber 102 is equal to the width of the main water chamber 101, so that the secondary water chamber 102 has a larger width, making it convenient for users to add water to the secondary water chamber 102.

[0054] Of course, in specific implementations, the water cavity 100 on the main unit 1 is not limited to a rectangular water cavity, but can be located along the direction perpendicular to the two opposite inner walls of the main water cavity 101 (e.g., Figure 9 (As indicated by arrow b in the diagram), the width of the secondary water cavity 102 may not be equal to the width of the primary water cavity 101; for example, the width of the secondary water cavity 102 may be smaller than the width of the primary water cavity 101. For example, refer to... Figure 9As shown, the auxiliary water chamber 102 can be located at one corner of the main water chamber 101, thereby reducing the space occupied by the auxiliary water chamber 102 on the main unit 1, so that more space can be left on the main unit 1 to arrange other structures.

[0055] In some embodiments, refer to Figure 9 and Figure 10 As shown, the secondary water cavity 102 is located at one corner of the main water cavity 101. A connecting port 104 is formed between two adjacent inner walls of the main water cavity 101, connecting the main water cavity 101 and the secondary water cavity 102. Supporting steps 11 are formed on the two adjacent inner walls of the main water cavity 101. The partition plate 21 includes a main body 212 and a side wall 223. The main body 212 is disposed at the connecting port 104. One end of the main body 212 is bent and extended in the direction away from the secondary water cavity 102 to form the side wall 223. The side edge of the main body 212 away from the side wall 223 and the side edge of the side wall 223 away from the main body 212 respectively form abutment surfaces 211.

[0056] In the above embodiments, by placing the auxiliary water chamber 102 at one corner of the main water chamber 101, the space occupied by the auxiliary water chamber 102 on the main unit 1 is reduced, so that more space can be left on the main unit 1 to arrange other structures; by forming abutment surfaces 211 on the main body 212 and side wall 223 of the partition plate 21 respectively, abutting and cooperating with the support steps 11 formed on the two adjacent inner side walls of the main water chamber 101, the vertical edges on both sides of the partition plate 21 abutting and cooperating with the inner side walls of the main water chamber 101 respectively, thereby reducing the steam overflow from the main water chamber 101.

[0057] In some embodiments, refer to Figure 7 and Figure 8 As shown, an inlet 103 is formed between the lower end face of the partition plate 21 and the bottom face of the auxiliary water cavity 102, and the supporting step 11 extends downward from the opening edge of the water cavity 100 to the upper edge of the inlet 103.

[0058] In the above embodiment, water in the auxiliary water chamber 102 can enter the main water chamber 101 through the inlet 103; and by setting a support step 11 that extends downward from the edge of the water chamber 100 to the upper edge of the inlet 103, the continuity of the seal between the contact surface 211 and the support step 11 is ensured, thereby better reducing the risk of steam overflow. When the water level in the main water chamber 101 is higher than the upper edge of the inlet 103, a water seal can be formed. Thus, through the contact and cooperation between the vertical edges of the partition plate 21 on both sides and the inner wall of the main unit 1, and the water seal, a good effect of preventing steam overflow is achieved.

[0059] Specifically, the fitting gap above the water level in the water cavity 100 can form a good sealing effect by the abutting surfaces 211 of the vertical edges on both sides of the partition plate 21 and the supporting steps 11 on the inner side wall of the main unit 1. The fitting gap below the water level in the water cavity 100, such as the gap between the bottom of the partition plate 21 and the bottom wall of the water cavity 100, can be sealed by the water in the water cavity, thereby forming an effective seal in the entire height direction of the water cavity 100 and achieving the effect of preventing steam from overflowing.

[0060] In some embodiments, refer to Figure 5 , Figure 6 and Figure 7 As shown, the bottom of the secondary water cavity 102 is provided with a boss 13, the top surface of the boss 13 forms the bottom surface of the secondary water cavity 102, and the bottom surface of the secondary water cavity 102 is higher than the bottom surface of the main water cavity 101; the partition plate 21 is inserted on one side of the boss 13, and the height of at least part of the lower end surface of the partition plate 21 is lower than the height of the top surface of the boss 13.

[0061] In the above embodiment, by providing a boss 13 at the bottom of the auxiliary water cavity 102, when the juice receiving tray 2 is placed on the main unit 1, the partition plate 21 is inserted into one side of the boss 13, so that the boss 13 can be used to limit the partition plate 21 and limit the partition plate 21 to one side of the boss 13, thereby limiting the juice receiving tray 2 to the upper area of ​​the main water cavity 101.

[0062] To ensure that the water in the auxiliary water chamber 102 flows smoothly through the inlet 103 to the main water chamber 101, in some embodiments, refer to Figures 5 to 8 As shown, a ramp 14 is formed on the boss 13. The height of at least a portion of the surface of the ramp 14 is lower than the height of the lower end face of the partition plate 21, and an inlet 103 is formed between the ramp 14 and the lower end face of the partition plate 21.

[0063] In specific implementation, refer to Figure 5 , Figure 6 and Figure 8 As shown, the boss 13 has ramps 14 formed at both ends along the width direction perpendicular to the water cavity 100. That is, the boss 13 is along... Figure 6 The two ends of the direction indicated by the middle arrow b are respectively formed with ramps 14. The height of at least a portion of the surface of each ramp 14 is lower than the height of the lower end face of the partition plate 21, and an inlet 103 is formed between the ramp 14 and the lower end face of the partition plate 21. This arrangement forms inlets 103 at both ends of the boss 13, thereby increasing the flow area between the secondary water chamber 102 and the main water chamber 101, so that the water in the secondary water chamber 102 can flow more smoothly into the main water chamber 101.

[0064] In some embodiments, refer to Figure 8As shown, the lower end faces of the partition rib 21 at both ends, perpendicular to the width direction of the drip tray 2, are respectively formed with relief surfaces corresponding to the ramp 14. The relief surfaces gradually curve upwards and extend to form an inlet 103 between themselves and the surface of the ramp 14. This arrangement increases the flow area of ​​the inlet 103, better ensuring that the water in the secondary water chamber 102 flows more smoothly into the main water chamber 101.

[0065] In some embodiments, refer to Figure 3 , Figure 4 and Figure 7 As shown, the bottom of the juice receiving tray 2 is provided with a downward extending energy-concentrating ring rib 22, and the bottom surface of the water cavity 100 is provided with an upward extending surrounding rib 16. The energy-concentrating ring rib 22 and the surrounding rib 16 are inserted and matched to form a steam cavity. The lowest height of the partition plate 21 extending downward does not exceed the lowest height of the energy-concentrating ring rib 22 extending downward.

[0066] It should be noted that by setting an energy-concentrating ring rib 22 at the bottom of the drip tray 2, the energy-concentrating ring rib 22 can be inserted into the water cavity 100, and the energy-concentrating ring rib 22 can be located in the outer area of ​​the surrounding rib 16 in the water cavity 100, so as to concentrate the heat generated when the steam cooking appliance is heated in the inner area of ​​the surrounding rib 16 and the energy-concentrating ring rib 22, so as to achieve the purpose of quickly producing steam.

[0067] In the above embodiments, by setting the minimum height of the downward extension of the partition plate 21 not to exceed the minimum height of the downward extension of the energy-concentrating ring rib 22, the energy-concentrating ring rib 22 can be supported on the placement surface when the juice tray 2 is placed on a table or other placement surface, thereby allowing the juice tray 2 to be placed flat on the table or other placement surface.

[0068] Furthermore, it should be noted that in specific implementations, the method of forming a sealing seal by abutting the first mating part and the second mating part to reduce the overflow of steam in the main water chamber 101 is not limited to. Alternatively, the method of inserting the first mating part and the second mating part can be used to increase the flow path length when steam overflows, thereby reducing the overflow of steam in the main water chamber 101.

[0069] In some embodiments, vertically extending insertion ribs are formed at the vertical edges on both sides of the partition plate 21, and an insertion groove extending vertically downward from the opening edge of the water cavity 100 is formed on the inner side wall of the main unit 1. The insertion ribs form a first mating part, and the insertion grooves form a second mating part. The insertion ribs and the insertion grooves are inserted and mated.

[0070] In a specific implementation, the insertion groove can be an insertion recess formed on the inner side wall of the host 1, and the insertion rib is inserted into the insertion recess in a downward direction.

[0071] In the above embodiments, when the drip tray 2 is placed on the main unit 1, the insert rib and the insert groove are engaged. In this way, the length of the flow path of steam in the main water chamber 101 when it overflows through the gap between the insert rib and the insert groove is increased, thereby reducing the steam overflow. Furthermore, the steam in the main water chamber 101 will change its flow direction multiple times when it passes through the gap between the insert rib and the insert groove, thereby reducing the steam flow rate and further reducing the steam overflow.
