Description

Water tank devices and steam cooking appliances

[0001] The applicant declares that this application claims priority to the following Chinese patent applications filed on March 26, 2025, with application number "202520552300.4" and title "Steam Cooking Appliance"; filed on March 26, 2025, with application number "202520552208.8" and title "Water Tank Device and Steam Cooking Appliance"; filed on March 26, 2025, with application number "202520550954.3" and title "Water Tank Device and Steam Cooking Appliance"; and filed on March 26, 2025, with application number "202520550945.4" and title "Steam Cooking Appliance", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of household appliance technology, and more specifically, to a water tank device and a steam cooking appliance. Background Technology

[0003] The oven with steam function in the relevant solutions includes a retractable water tank assembly. There are two methods for this retraction: the first is motor-controlled retraction, and the second is manual retraction via a spring-loaded mechanism. Both of these structures require additional spring-loaded mechanisms or motors, making the system more complex and increasing product costs.

[0004] Therefore, designing a simple and low-cost telescopic water tank assembly and steam oven has become an urgent problem to be solved.

[0005] Application content

[0006] This application aims to at least address the problems of complex structure and high cost of steam ovens in the prior art or related technologies.

[0007] The first objective of this application is to provide a water tank device.

[0008] The second objective of this application is to provide a steam cooking appliance.

[0009] An embodiment of the first aspect of this application provides a water tank device, comprising: a mounting housing including a mounting cavity, one end of which is provided with a first mounting port; a first limiting member mounted on the mounting housing; a water tank assembly capable of sliding into a first position within the mounting cavity or sliding out of the mounting cavity from the first mounting port, the water tank assembly including a second limiting member; and an elastic member mounted between the water tank assembly and the mounting housing. When the water tank assembly is in the first position within the mounting cavity, the first limiting member and the second limiting member engage with each other to lock the water tank assembly, and the elastic member is in a compressed state. When the water tank assembly is in the first position, pressing the water tank assembly into the mounting cavity can release the limiting between the first limiting member and the second limiting member, thereby unlocking the water tank assembly and causing the elastic member to extend. The extension of the elastic member can push the water tank assembly to a second position, in which a portion of the water tank assembly extends out of the first mounting port.

[0010] The water tank device provided according to the embodiments of this application can be specifically used in steam cooking appliances, such as ovens. The water tank device specifically includes a mounting housing and a water tank assembly. The water tank assembly can be pressed into or ejected from the mounting housing. The water tank assembly and the mounting housing can be locked and unlocked by a first limiting member and a second limiting member. After the water tank assembly is unlocked, it can be removed from the mounting housing for adding water, cleaning, or repair / replacement. When the water tank assembly is locked, the fit between the water tank assembly and the mounting housing is good, and the water tank assembly is not prone to shaking, thus preventing it from slipping out of the mounting housing.

[0011] In this design, installing the water tank assembly simply requires pushing it into the housing. Removing the assembly is achieved by pressing it; the elastic element releases the water tank, allowing it to be detached for adding water or cleaning. This design eliminates the need for a motor or ejector, simplifying the water tank assembly and reducing costs. Furthermore, the water tank assembly itself features a second limiting element, allowing the elastic element to directly engage with the assembly. This first limiting element further secures the assembly, ensuring reliable positioning and a more stable installation within the housing, preventing loosening.

[0012] Furthermore, this design integrates the mechanism for driving the water tank assembly's rebound directly into the water tank assembly and the mounting housing, simplifying the overall structure of the water tank device and thus reducing product costs. In addition, this structure uses the water tank assembly itself as the rebound component, making the pressing and ejection of the water tank assembly more reliable.

[0013] The second aspect of this application provides a steam cooking appliance, including: a water tank device provided in any embodiment of the first aspect.

[0014] The steam cooking appliance provided according to the embodiments of this application has all the beneficial effects of the water tank device provided in any embodiment of the first aspect since it includes the water tank device provided in any embodiment of the first aspect, which will not be repeated here.

[0015] An embodiment of the third aspect of this application provides a water tank device for a steam cooking appliance. The water tank device includes: a water tank assembly, which includes a water-containing chamber, a water outlet channel, and a valve assembly. The water outlet channel communicates with the water-containing chamber, and the valve assembly is movably installed in the water outlet channel and is movable between a first position and a second position. The water outlet channel includes a water outlet, and the valve assembly includes a seal. When the valve assembly is in the first position, the seal blocks the water outlet, and when the valve assembly is in the second position, the seal opens the water outlet.

[0016] The water tank device provided according to the embodiments of this application can be specifically used in steam cooking appliances, such as ovens. The water tank device specifically includes a water tank assembly. The water tank assembly includes a water outlet channel through which water in the water tank assembly can be discharged. A valve assembly is provided within the water outlet channel, which can be used to open and close the water outlet channel.

[0017] An embodiment of the fourth aspect of this application provides a steam cooking appliance, including: a water tank device provided in any embodiment of the third aspect.

[0018] The steam cooking appliance provided according to the embodiments of this application has all the beneficial effects of the water tank device provided in any of the third aspects embodiments since it includes the water tank device provided in any of the third aspects embodiments, which will not be repeated here.

[0019] An embodiment of the fifth aspect of this application provides a steam cooking appliance, comprising: a housing including a cooking cavity, wherein a food inlet / outlet and a first mounting port are provided at a first end of the housing along a first direction, the food inlet / outlet communicating with the cooking cavity; a door installed at the first end of the housing to open or close the food inlet / outlet; at least one heating device installed on the housing for heating food in the cooking cavity; a water receiving box installed inside the cooking cavity and disposed near the at least one heating device so that water in the water receiving box can be heated into steam; and a water tank assembly capable of being inserted into the housing along the first direction through the first mounting port, wherein when the water tank assembly is installed on the housing, the water tank assembly is located outside the cooking cavity, the length direction of the water tank assembly is disposed along the first direction, and the water tank assembly includes a water outlet channel communicating with the water receiving box.

[0020] The steam cooking appliance provided according to the embodiments of this application can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly, a heating device, and a water collection box. The housing assembly includes a housing body and a door. A cooking chamber is provided inside the housing body for placing and heating food. The door is used to open and close the cooking chamber. The heating device is installed inside the cooking chamber and is capable of heating the food. The water collection box is used to store water and is located close to at least one heating device, so that the water in the water collection box can be heated into steam by the heating device to humidify and replenish the food in the cooking chamber. With this structure, the water collection box can be heated using the existing heating device inside the housing body, eliminating the need for an additional complex steam generator, thus simplifying the product structure and reducing product costs. Furthermore, this structure allows water to be added to the water collection box via the water tank assembly, eliminating the need for the user to manually add water to the water collection box, thereby improving the user experience.

[0021] Meanwhile, the first installation port and the food inlet / outlet are located on the same side, allowing the water tank assembly to be inserted and installed into the cabinet from the side with the door. This enables users to install and remove the water tank assembly from the front of the product, making its operation more convenient. Furthermore, the water tank assembly is placed front-to-back on the cabinet, meaning it is installed horizontally, not vertically. This reduces the space occupied by the water tank assembly, preventing the entire product from being too tall, and allows the water tank assembly to be installed at the top of the cooking cavity, thus providing conditions for the water tank assembly to be lowered by gravity.

[0022] An embodiment of the sixth aspect of this application provides a steam cooking appliance, including: a housing, the housing including a cooking cavity; a water collection box installed inside the cooking cavity and disposed near the top of the cooking cavity; and a heating device installed inside the cooking cavity and located at the top of the cooking cavity for heating the water collection box to heat the water in the water collection box into steam.

[0023] The steam cooking appliance provided according to the embodiments of this application can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly, a heating device, and a water collection box. The housing assembly includes a housing body and a door, and the housing body has a cooking cavity for placing and heating food. The heating device is installed on the top of the cooking cavity and can heat the water collection box, which stores water. The water in the water collection box can be heated into steam by the heating device to humidify and replenish the food in the cooking cavity.

[0024] In this application, the water collection box is positioned at or near the top of the cooking cavity, thus placing it relatively high. When using a steam cooking appliance, food is typically placed in the lower middle part of the cooking cavity, leaving the top empty. This application, by placing the water collection box near the top of the cooking cavity, fully utilizes the space at the top, improving the space utilization rate of the cooking cavity, and ensuring that the placement of the water collection box does not affect the actual usable volume of the cooking cavity.

Detailed Implementation

[0051] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0053] The water tank device 100 and steam cooking appliance 200 provided in the embodiments of this application will be described below with reference to Figures 1 to 22.

[0054] As shown in Figures 1, 2 and 3, an embodiment of this application provides a water tank device 100, including: a mounting shell 1, including a mounting cavity 12, one end of which is provided with a first mounting port 14; and a water tank assembly 3, which can slide into a first position in the mounting cavity 12 or slide out of the mounting cavity 12 through the first mounting port 14.

[0055] For example, as shown in Figures 1, 2, and 3, the water tank device 100 further includes: a first limiting member 2, installed on the mounting housing 1. The water tank assembly 3 includes a second limiting member 32; an elastic member 4, installed between the water tank assembly 3 and the mounting housing 1. When the water tank assembly 3 is in the first position within the mounting cavity 12, the first limiting member 2 and the second limiting member 32 are engaged to lock the water tank assembly 3, and the elastic member 4 is in a compressed state. When the water tank assembly 3 is in the first position, pressing the water tank assembly 3 into the mounting cavity 12 can release the limiting between the first limiting member 2 and the second limiting member 32, thereby unlocking the water tank assembly 3 and causing the elastic member 4 to extend. The extension of the elastic member 4 can push the water tank assembly 3 to a second position, in which a portion of the water tank assembly 3 extends out of the first mounting opening 14.

[0056] The water tank device 100 provided according to the embodiments of this application can be specifically used in a steam cooking appliance 200, such as an oven. The water tank device 100 specifically includes a mounting housing 1 and a water tank assembly 3. The water tank assembly 3 can be pressed into or ejected from the mounting housing 1. The water tank assembly 3 and the mounting housing 1 can be locked and unlocked by a first limiting member 2 and a second limiting member 32. After the water tank assembly 3 is unlocked, it can be removed from the mounting housing 1 for adding water, cleaning, or repair / replacement. When the water tank assembly 3 is locked, the fit between the water tank assembly 3 and the mounting housing 1 is good, preventing the water tank assembly 3 from easily shaking and thus preventing it from slipping out of the mounting housing 1.

[0057] In this structure, when installing the water tank assembly 3, it is only necessary to push the water tank assembly 3 into the mounting housing 1. When it is necessary to remove the water tank assembly 3, pressing the water tank assembly 3 will release the constraint on the water tank assembly 3 under the rebound action of the elastic member 4, thus allowing the water tank assembly 3 to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or pop-out device for disassembly of the water tank assembly 3, simplifying the structure of the water tank device 100 and reducing its cost. Furthermore, this structure includes a second limiting member 32 on the water tank assembly 3 itself, allowing the elastic member 4 to directly act on the water tank assembly 3, thereby directly limiting the water tank assembly 3 through the first limiting member 2. This makes the limiting of the water tank assembly 3 more reliable and also makes the installation of the water tank assembly 3 within the mounting housing 1 more stable, preventing the water tank assembly 3 from loosening.

[0058] Furthermore, this design integrates the structure that drives the water tank assembly 3 to rebound directly into the water tank assembly 3 and the mounting housing 1, simplifying the overall structure of the water tank device 100 and thus reducing product costs. In this structure, the water tank assembly 3 itself acts as the rebound component, making the pressing and ejection of the water tank assembly 3 more reliable.

[0059] In any of the above embodiments, for example, the water tank assembly 3 includes a water tank housing 30, and a second limiting member 32 is disposed on the water tank housing 30.

[0060] In these embodiments, the water tank assembly 3 includes a water tank housing 30 for holding water. A second limiting member 32 is used to limit the position of the water tank assembly 3 within the mounting housing 1.

[0061] In any of the above embodiments, for example, the second limiting member 32 and the water tank shell 30 are an integral structure.

[0062] In these embodiments, the second limiting member 32 can be a protruding structure or a recessed structure on the water tank outer shell 30. The second limiting member 32 and the water tank outer shell 30 are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member 32 and the water tank outer shell 30 can be separately provided, and then the second limiting member 32 can be detachably installed on the water tank outer shell 30.

[0063] In any of the above embodiments, exemplarily, as shown in FIG3, the second limiting member 32 includes a guide slide 320, the guide slide 320 including a limiting groove 327; the first limiting member 2 includes a movable member 22, the movable member 22 is mounted on the mounting housing 1, and a portion of the movable member 22 is located within the guide slide 320; when the water tank assembly 3 is installed in the first position within the mounting cavity 12, at least a portion of the movable member 22 can move from the first end of the guide slide 320 to the limiting groove 327 and be limited within the limiting groove 327; when the water tank assembly 3 is in the first position, pressing the water tank assembly 3 into the mounting cavity 12 allows the movable member 22 to move along the guide slide 320 to separate from the limiting groove 327, thereby unlocking the water tank assembly 3 and causing the elastic member 4 to extend.

[0064] In these embodiments, the first limiting member 2 includes a movable member 22. When the water tank assembly 3 is installed inside the mounting housing 1 or removed from the mounting housing 1, the movable member 22 can move relative to the water tank assembly 3. A limiting groove 327 is provided in the guide slide 320, which restricts the movable member 22 to ensure that the water tank assembly 3 can be locked in the first position. Subsequently, when it is necessary to remove the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 to move inward. This allows the movable member 22 to move again to a position separated from the limiting groove 327, thus limiting the water tank assembly 3 and placing it in an unlocked state. After the water tank assembly 3 is unlocked, the elastic member 4 can rebound, pushing the water tank assembly 3 a distance outward from the mounting housing 1, thereby automatically ejecting the water tank. This facilitates subsequent disassembly of the water tank assembly 3 for cleaning, adding water, or maintenance.

[0065] In any of the above embodiments, for example, as shown in FIG3, when the water tank assembly 3 is in the first position, pressing the water tank assembly 3 into the mounting cavity 12 allows at least a portion of the movable member 22 to move toward the second end of the guide slide 320 until it separates from the limiting groove 327.

[0066] In these embodiments, when the water tank assembly 3 is pulled out of the mounting housing 1, the movable member 22 can continue to slide as before, instead of sliding back. This arrangement ensures that the movement path of the movable member 22 is inconsistent when the water tank assembly 3 is inserted into the mounting housing 1 and when it is pulled out of the mounting housing 1, thereby making the locking and unlocking engagement between the movable member 22 and the guide slide 320 more reliable.

[0067] Conversely, when the water tank assembly 3 is unlocked, at least a portion of the movable part 22 can also move back toward the first end of the guide slide 320 until the movable part 22 separates from the limiting groove 327.

[0068] In Figure 3, the arrows indicate the movement path of the moving part 22 during the installation and unlocking of the water tank assembly 3.

[0069] In any of the above embodiments, as exemplarily shown in Figures 1, 2 and 3, the movable member 22 includes a slider 24, which is capable of sliding along the guide slide 320 and is confined to the limiting groove 327 when the water tank assembly 3 is in the first position.

[0070] In these embodiments, the movable component 22 includes a sliding component 24. The sliding component 24 slides along the guide slide 320, allowing the water tank assembly 3 to be inserted and removed. Simultaneously, after the water tank assembly 3 is inserted and installed in its first position, the sliding component 24 is better engaged in the limiting groove 327, thus preventing the sliding component 24 from sliding and locking the water tank assembly 3. When it is necessary to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inward to retract the limiting groove 327, causing the sliding component 24 to slide out of the limiting groove 327 along the second guide surface 324. This releases the limiting engagement between the sliding component 24 and the limiting groove 327, freeing the water tank assembly 3 and facilitating its removal for heating, adding water, cleaning, or repair / replacement.

[0071] In any of the above embodiments, exemplarily, as shown in FIG3, the guide slide 320 includes: a first guide surface 322; a second guide surface 324, which is set at a first angle to the first guide surface 322, and a limiting groove 327 is formed by the first guide surface 322 and the second guide surface 324; a first slide 326, wherein the first guide surface 322 is disposed at the second end of the first slide 326, and the first slide 326 is used to guide the sliding member 24 from the first end of the first slide 326 during the process of the water tank assembly 3 sliding from the first mounting port 14 into the mounting cavity 12 to the third position. Move to the first guide surface 322; when the water tank assembly 3 is in the third position, release the water tank assembly 3, and the water tank assembly 3 moves to the first position outside the mounting cavity 12 under the action of the elastic member 4. The sliding member 24 slides along the first guide surface 322 to the connection between the first guide surface 322 and the second guide surface 324, and is limited to the connection between the first guide surface 322 and the second guide surface 324; when the water tank assembly 3 is in the first position, press the water tank assembly 3 into the mounting cavity 12, and the sliding member 24 can move along the second guide surface 324 to separate from the limiting groove 327.

[0072] In these embodiments, the first guide surface 322 and the second guide surface 324 can be connected to form a limiting groove 327. After the water tank assembly 3 is installed in place, the sliding member 24 is limited within the limiting groove 327 by the rebound force of the elastic member 4. Thus, through the interaction between the limiting groove 327 and the sliding member 24, the position of the water tank assembly 3 can be limited, preventing the water tank assembly 3 from falling out of the mounting cavity 12 without other external forces. In order to guide the sliding member 24 to enter the limiting groove 327 formed by the first guide surface 322 and the second guide surface 324 normally, a first slide rail 326 is provided. Through the first slide rail 326, the sliding member 24 can be guided to move along a preset trajectory. This ensures that after the water tank assembly 3 is installed in place, the sliding member 24 can just reach the bottom of the limiting groove 327, and the sliding member 24 will not be stuck in advance, which would prevent the water tank assembly 3 from being installed correctly.

[0073] When it is necessary to disassemble the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 so that the other end of the sliding member 24 can move along the second guide surface 324 to separate from the limiting groove 327, thereby releasing the locking of the mounting housing 1 to the water tank assembly 3, so that the water tank assembly 3 can be pulled out from the mounting housing 1, thereby realizing the disassembly of the water tank assembly 3 relative to the mounting housing 1.

[0074] In any of the above embodiments, as exemplarily shown in FIG3, the guide slide 320 further includes: a second slide 328, one end of the second slide 328 being connected to the end of the second guide surface 324 away from the first guide surface 322. When the water tank assembly 3 is in the first position, the water tank assembly 3 is pressed into the mounting cavity 12, and the sliding member 24 can move along the second guide surface 324 into the second slide 328; during the process of the water tank assembly 3 sliding out of the mounting cavity 12 from the first mounting port 14, the sliding member 24 can move along the second slide 328.

[0075] In these embodiments, the guide slide 320 further includes a second slide 328. When the water tank assembly 3 is pulled out from the mounting housing 1, the slider 24 can slide along the second slide 328, thereby limiting the position of the slider 24 and guiding the water tank assembly 3 to prevent the water tank assembly 3 from shifting and jamming with the mounting housing 1.

[0076] Furthermore, in this structure, when the water tank assembly 3 is inserted into the mounting housing 1 and when the water tank assembly 3 is pulled out of the mounting housing 1, the movement paths of the sliding member 24 are not consistent and form a loop, thereby making the locking and unlocking cooperation between the sliding member 24 and the guide slide 320 more reliable.

[0077] Conversely, the second slide rail 328 may not be provided, and the structure of the first slide rail 326 and the first guide surface 322 may be reasonably designed so that when the water tank assembly 3 is unlocked, the other end of the sliding member 24 can return to the first slide rail 326 along the first guide surface 322.

[0078] In any of the above embodiments, as exemplarily shown in FIG3, the guide slide 320 further includes: an expansion section 329 disposed at the first end of the first slide 326, and a fourth guide surface 3292 disposed on the two inner sidewalls of the expansion section 329. The fourth guide surface 3292 is used to guide the sliding member 24 to move into the first slide 326 during the process of the water tank assembly 3 sliding from the first mounting port 14 into the mounting cavity 12.

[0079] In these embodiments, since the slider 24 has a certain sliding range, its position is not fixed after the water tank assembly 3 is removed. After the water tank assembly 3 is correctly inserted into the mounting housing 1, the slider 24 can always fall within the range of the outward expansion section 329. When the water tank assembly 3 is inserted inward, the slider 24 can be guided into the first slide rail 326 by the fourth guide surface. This structure allows the slider 24 to slide into the first slide rail 326 regardless of its initial position, and then move along a fixed trajectory to the limiting part. Thus, before installing the water tank assembly 3, it is not necessary to reset the slider 24 or specifically determine its position, making the installation of the water tank assembly 3 more convenient.

[0080] Of course, in other solutions, the outer extension section 329 and the fourth guide surface 3292 may not be set. In this case, in order to ensure that the slider 24 can slide into the first slide rail 326, the position of the slider 24 needs to be fixed in advance.

[0081] In any of the above embodiments, as exemplarily shown in FIG1, a limiting hole 10 is provided on the mounting housing 1, and the sliding member 24 is slidably mounted on the limiting hole 10, thereby limiting the sliding range of the sliding member 24.

[0082] In these embodiments, to prevent the slider 24 from sliding excessively, a limiting hole 10 is provided on the mounting housing 1. The limiting hole 10 can limit the sliding range of the slider 24, so that the slider 24 can only move within a predetermined area. This can limit the position of the slider 24 and prevent the slider 24 from moving to other positions and failing to cooperate with the second limiting member 32 on the water tank assembly 3. This ensures that after the water tank assembly 3 is installed on the water tank housing 30, the slider 24 can always cooperate with the second limiting member 32 to lock the water tank assembly 3.

[0083] In any of the above embodiments, as exemplarily shown in FIG1, the movable member 22 includes: a rotating member 26, the first end of the rotating member 26 being rotatably mounted on the outside of the mounting housing 1, the mounting housing 1 being provided with a limiting hole 10, the second end of the rotating member 26 passing through the limiting hole 10 and inserted into the mounting cavity 12, and a sliding member 24 being disposed on the second end of the rotating member 26, the sliding member 24 and the rotating member 26 being an integral structure, or the sliding member 24 and the rotating member 26 being detachably connected.

[0084] In these embodiments, the movable member 22 includes a rotating member 26, and a sliding member 24 is disposed on the rotating member 26. The sliding member 24 can be slidable by rotating the rotating member 26. This structure allows for relatively convenient sliding installation of the sliding member 24.

[0085] The sliding member 24 and the rotating member 26 can be formed as a single part, for example, they can be integrally molded or processed separately and then connected to form a single structure. Alternatively, the sliding member 24 and the rotating member 26 can also be two completely independent parts.

[0086] In any of the above embodiments, as exemplarily shown in FIG1, the water tank device 100 further includes: a press-fitting member 5 disposed outside the mounting housing 1, and at least a portion of the rotating member 26 located between the press-fitting member 5 and the mounting housing 1.

[0087] In these embodiments, the press-fitting member 5 is used to press the rotating member 26 toward the water tank assembly 3. This can limit the position of the rotating member 26 so that the rotating member 26 can abut against the water tank assembly 3, and prevent the rotating member 26 from separating from the water tank assembly 3 during rotation.

[0088] In any of the above embodiments, the press-fitting member 5 is elastic, which allows it to press the rotating member 26 toward the water tank assembly 3.

[0089] In these embodiments, the press-fitting member 5 can be configured as an elastic structure, so that the elastic force of the press-fitting member 5 can press the rotating member 26, so that the other end of the rotating member 26 can always abut against the water tank assembly 3, avoiding the situation where the other end of the rotating member 26 separates from the water tank assembly 3 and the water tank assembly 3 cannot be locked.

[0090] In any of the above embodiments, as exemplarily shown in FIG1, the water tank device 100 further includes a support structure 18 disposed on the outer wall of the mounting housing 1 and supported on the side of the rotating member 26 near the mounting housing 1.

[0091] In this embodiment, in order to limit the height position of the rotating component 26, a support structure 18 is provided on the mounting housing 1 to support the rotating component 26. The support structure 18 can better limit the installation height of the rotating component 26. At the same time, the support structure 18 can also reduce the contact area between the rotating component 26 and the mounting housing 1, thereby reducing the friction between the rotating component 26 and the mounting housing 1.

[0092] In any of the above embodiments, exemplarily as shown in Figures 4, 5, 7, and 8, the water tank assembly 3 includes: a water tank housing 30, the water tank housing 30 including a water outlet channel 34; a valve assembly 36, installed at the water outlet channel 34, for opening or closing the water outlet channel 34; a push rod 16 is provided on the mounting housing 1, the push rod 16 is used to insert into the water outlet channel when the water tank assembly 3 is installed in the first position, and push the valve assembly 36 to move to open the water outlet channel 34. After the water tank assembly 3 slides out of the mounting cavity 12, the valve assembly 36 returns to the position of closing the water outlet channel 34, so that the water outlet channel 34 is closed.

[0093] In these embodiments, the water tank assembly 3 includes a water tank shell 30, which includes a water outlet channel 34 through which water can be discharged from the water tank assembly 3. A valve assembly 36 is provided within the water outlet channel 34, allowing the water outlet channel 34 to be opened and closed. For example, when the water tank assembly 3 is detached from the cooking appliance and water is added, the water outlet channel 34 can be closed via the valve assembly 36 to facilitate adding water to the water tank assembly 3. When the water tank assembly 3 is installed on the cooking appliance and steam is required, the water outlet channel 34 can be opened to facilitate the output of water from the water tank assembly 3.

[0094] In any of the above embodiments, exemplarily as shown in Figures 4 and 5, the valve assembly 36 includes: a valve stem 38 slidably mounted within the water outlet channel 34, the valve stem 38 being able to move between a fourth position and a fifth position under the action of the push rod 16; an elastic member 4 located within the water outlet channel 34, one end of the elastic member 4 being connected to the valve stem 38, and the other end of the elastic member 4 being connected to the inner wall of the water outlet channel 34; and a sealing member 39 mounted on the valve stem 38, capable of following the movement of the valve stem 38 to open or seal the water outlet channel 34.

[0095] In this embodiment, the valve assembly 36 specifically includes a valve stem 38, an elastic element 4, and a seal 39. The valve stem 38 is slidably mounted within the water outlet channel 34. The seal 39 is mounted on one end of the valve stem 38 and can move with the valve stem 38, thereby opening or closing the water outlet channel 34 by moving the seal 39. The elastic element 4 is generally a spring. The elastic element 4 is abutted between the valve stem 38 and the water tank housing 30. Under normal conditions, the elastic element 4 is in a compressed state. The rebound force of the elastic element 4 can compress the seal 39, so that the seal 39 can close the water outlet channel 34. When the valve stem 38 is pushed along the water outlet channel 34, the valve stem 38 can drive the seal 39 to move and open the water outlet channel 34, so that water in the water tank assembly 3 can flow out. Meanwhile, during this process, the elastic element 4 is compressed. Therefore, after the external force on the valve stem 38 disappears, the elastic element 4 can drive the valve stem 38 to return to its initial position, thereby causing the seal 39 to close the water outlet channel 34 again.

[0096] Specifically, a push rod 16 can be installed on the cooking cabinet at the position corresponding to the water outlet channel 34. After the water tank assembly 3 is installed on the cooking cabinet, the push rod 16 can be inserted into the water outlet channel 34, thereby pushing the valve rod 38 to move along the water outlet channel 34, thus opening the water outlet channel 34. After the water tank assembly 3 is removed, the external force exerted by the push rod 16 on the valve rod 38 disappears, and the valve rod 38 and the seal 39 are reset under the action of the elastic force of the elastic member 4, thereby closing the water outlet channel 34 of the water tank assembly 3, so that water cannot flow from the water outlet channel 34 of the water tank assembly 3.

[0097] In this embodiment, the elastic element used for the telescopic installation of the water tank assembly 3 and the elastic element required for the valve assembly 36 are the same part. That is, the pop-up structure of the water tank assembly and the opening and closing structure of the water outlet of the water tank assembly share the same elastic element, which simplifies the structure of the product.

[0098] Of course, in other solutions, the elastic element for the telescopic installation of the water tank assembly 3 and the elastic element required for the valve assembly 36 can also be two separate parts.

[0099] For example, one end of the valve stem 38 passes through the inlet of the water outlet channel 34 and enters the water-containing chamber. The seal 39 is sealed and installed at the inlet of the water outlet channel 34. Pushing the valve stem 38 along the water outlet channel 34 causes the seal 39 to move away from the outlet of the water outlet channel 34, thereby opening the inlet of the water outlet channel 34. In this configuration, the seal 39 is located at the inlet of the water outlet channel 34, allowing the entire water outlet channel 34 to be opened and closed by opening or closing the inlet of the water outlet channel 34.

[0100] In any of the above embodiments, as exemplarily shown in Figures 4, 5 and 6, the water outlet channel 34 includes an outlet 342 and an inlet 344. When the valve stem 38 is in the fourth position, the seal 39 blocks the outlet 342. When the valve stem 38 is in the fifth position, the seal 39 opens the outlet 342, so that the inlet 344 and the outlet 342 are connected.

[0101] In these embodiments, the seal 39 is disposed within the water outlet channel 34 and near the water outlet 342. When the water tank assembly 3 is not installed into the mounting housing 1, the valve stem 38 is in the fourth position, and the seal 39 blocks the water outlet 342, preventing water in the water tank housing 30 from leaking out through the water outlet channel 34. When the water tank assembly 3 is installed into the mounting housing 1, the push rod 16 is inserted into the water outlet channel 34 and pushes up the valve stem 38, placing it in the fifth position. At this time, the elastic element 4 is compressed, and the seal 39 and the valve stem 38 move together to the other side of the water inlet 344, connecting the water outlet 342 and the water inlet 344. This allows water in the water tank housing 30 to be discharged through the water outlet channel 34, facilitating water supply to the steam cooking appliance 200. When it is necessary to remove the water tank assembly 3, the limiting position between the water tank assembly 3 and the housing assembly is released, the valve stem 38 rebounds under the action of the elastic element 4, and the entire water tank assembly 3 is ejected. With this structure, when the water tank assembly 3 is ejected, the seal 39 can move along the outlet of the water outlet channel 34. In this way, the seal 39 can squeeze out the remaining water in the water outlet channel 34, avoiding the presence of too much water in the water outlet channel 34. This prevents the water tank assembly 3 from leaking when it is removed, thus avoiding any impact on the user experience.

[0102] Conversely, as shown in Figures 7 and 8, the seal 39 can be positioned at the inlet 344. When the water tank assembly 3 is not installed in the mounting housing, the seal 39 seals the inlet 344. When the water tank assembly 3 is installed in the mounting housing 1, the push rod 16 pushes the valve rod 38 forward, causing the seal 39 to extend out of the outlet channel 34, thereby opening the inlet of the outlet channel 34 and allowing water to drain from the water tank assembly 3. However, with this configuration, since the outlet channel 34 has a certain length and is generally placed horizontally, some residual water will remain in the outlet channel 34 after the water tank assembly 3 is unlocked. During the removal of the water tank assembly 3, this water will fall out, thus reducing the user experience.

[0103] For example, the water outlet channel 34 can be tilted slightly downward from the inlet to the outlet, which can also reduce the residual water in the water outlet channel 34.

[0104] In any of the above embodiments, as exemplarily shown in Figures 5 and 7, the elastic element 4 includes a spring capable of stretching or shortening.

[0105] In these embodiments, the use of a spring that can extend or shorten provides better elasticity to eject the water tank assembly 3 when it needs to be removed from the steam cooking appliance 200. Simultaneously, the spring also allows the valve body assembly to return to its initial installation position to block the water outlet passage 34, thereby preventing leakage of the water tank assembly 3 after it has been removed from the steam cooking appliance 200.

[0106] Of course, the elastic element 4 can also be other structures with a certain degree of elasticity and hardness, such as metal springs or rubber parts.

[0107] As shown in Figure 9, an embodiment of this application provides a steam cooking appliance 200, including the water tank device 100 provided in any of the above embodiments.

[0108] The steam cooking appliance 200 provided according to the embodiments of this application includes the water tank device 100 provided in any of the above embodiments. Therefore, the steam cooking appliance 200 has all the beneficial effects of the water tank device 100 provided in any of the above embodiments, which will not be repeated here.

[0109] In any of the above embodiments, exemplarily as shown in Figures 9 and 10, the steam cooking appliance 200 includes a housing 6 and a door 7. The housing 6 includes a cooking cavity 62, and a food inlet / outlet 64 is provided at a first end along a first direction, communicating with the cooking cavity 62. The door 7 is installed at the first end to open or close the food inlet / outlet 64. A water tank shell 30 is installed on the housing 6 and is arranged along the first direction, with a first mounting opening 14 located at the first end of the housing 6 along the first direction.

[0110] The steam cooking appliance 200 provided according to an embodiment of this application includes a cooking chamber and a water tank assembly 3. The cooking chamber generates steam and performs cooking functions. The water tank assembly 3 is detachably installed on the cooking chamber to supply water to the cooking chamber. The cooking chamber includes a body 6 and a door 7. A cooking cavity 62 is provided inside the body 6, and the cooking cavity 62 communicates with a food inlet / outlet 64. The door 7 is installed on the body 6 and is used to open and close the food inlet / outlet 64. The water tank assembly 3 is installed on the side of the body 6 where the door 7 is provided, for example, on the front side of the body 6. The water tank assembly 3 can also be installed on the body 6 along the front side, and it can be pulled out in the front-back direction to achieve disassembly and assembly. Furthermore, the water tank assembly 3 is also placed front-back on the body 6, that is, it is installed horizontally on the body 6, not vertically.

[0111] For example, as shown in Figures 1 to 10, the water tank assembly 3 can be pulled and installed onto the tank body 6 through the first mounting port 14 along a first direction. The water tank assembly 3 includes: a water tank shell 30, which includes a water-containing cavity and a second inlet / outlet 307 communicating with the water-containing cavity, the second inlet / outlet 307 being disposed at one end of the water tank shell 30 along the first direction; a cover 302, which is detachably installed on the water tank shell 30 to open or close the second inlet / outlet 307; and a sealing ring, which is disposed between the water tank shell 30 and the cover 302 to seal the gap between the water tank shell 30 and the cover 302.

[0112] In this embodiment, the water tank assembly 3 specifically includes a water tank shell 30 and a cover 302. The water tank shell 30 is provided with a second inlet / outlet 307, and the cover 302 is detachably mounted on the second inlet / outlet 307 of the water tank shell 30. Meanwhile, to ensure a seal between the water tank shell 30 and the cover 302, a sealing ring is also provided between them. This sealing ring allows for a sealed connection between the two, thereby preventing water leakage from the water tank assembly 3.

[0113] In other oven designs, the water tank assembly typically has a water inlet directly on the side wall of the water tank shell without a removable cover. This makes it difficult to open the water tank and thus inconvenient for cleaning. In this application, a removable cover 302 is provided. This allows for easy cleaning of the water tank assembly 3 by opening the cover 302, improving the convenience of cleaning and ensuring cleanliness. Furthermore, this design allows users to easily inspect the interior of the water tank assembly 3 for dirt and grime, making it easier to detect and clean the assembly promptly. This provides users with greater peace of mind when using the water tank assembly 3.

[0114] The first direction can specifically refer to the front-to-back direction of the cooking cabinet. For example, the water tank assembly 3 can be disassembled and installed from the front of the cooking cabinet. The cover 302 and the outer shell 30 of the water tank assembly 3 are also assembled along the front-to-back direction, which means that the water tank assembly 3 is installed horizontally on the cooking cabinet, rather than vertically.

[0115] As shown in Figures 9 and 10, the water tank assembly 3 is positioned along the height direction of the steam cooking appliance 200, close to the top of the steam cooking appliance 200.

[0116] For example, steam cooking appliance 200 includes an oven. Of course, steam cooking appliance 200 can also be other devices that require a water tank.

[0117] In any of the above embodiments, as exemplarily shown in Figures 9 and 10, the steam cooking appliance 200 further includes: a heating device installed on the housing 6 for heating the food in the cooking cavity 62; a water receiving tank 94 installed in the cooking cavity 62 and capable of being heated by the heating device; and a connecting pipe 8 for connecting the water tank device 100 and the water receiving tank 94 to transport water in the water tank device 100 to the water receiving tank 94.

[0118] For example, water in the water tank device 100 can flow through the connecting pipe 8 into the water receiving tank 94 under the action of gravity.

[0119] In the above embodiments, as exemplarily shown in FIG2, the water tank shell 30 includes a first arc-shaped surface arranged along the circumferential direction of the water tank shell 30. The two ends of the first arc-shaped surface arranged along the circumferential direction of the water tank shell 30 are connected by a first outer wall surface. The first outer wall surface includes a first plane 304 and a second arc-shaped surface. An indicator structure 306 is provided on the first plane 304 to indicate the installation direction of the water tank assembly 3. The second arc-shaped surface is located on the side of the first plane 304 near the second inlet / outlet 307 of the water tank shell 30.

[0120] In this embodiment, the water tank outer shell 30 is generally cylindrical, with most of its outer wall surface being curved, such as an arcuate surface. However, at least a portion of the outer wall surface of the water tank outer shell 30 is a first plane 304. The first plane 304 facilitates the installation of the indicator structure 306, the first limiting structure of the water tank assembly 3, etc. For example, during processing, a cylindrical water tank can be machined first, and then a portion of the outer wall surface of the cylindrical water tank can be flattened to form the first plane 304.

[0121] In addition, by setting the first plane 304, it is also convenient for users to distinguish the front and back of the water tank shell 30, thereby avoiding incorrect installation of the water tank assembly 3.

[0122] For example, the first outer wall surface also includes a second arc-shaped surface. The second arc-shaped surface is located on the side of the first plane 304 near the second inlet / outlet 307 of the water tank shell 30. That is, the part of the first outer wall surface near the second inlet / outlet 307 is arc-shaped and not flat. This makes the outer wall surface around the entire second inlet / outlet 307 circular, so that the cover 302 can also be set to be circular. This makes the appearance of the entire water tank assembly 3 more beautiful. Especially when the water tank assembly 3 is used in ovens, it can make the shape of the water tank assembly 3 consistent with the knobs and other parts on the oven, thereby improving the overall aesthetics of the oven.

[0123] In the above embodiments, for example, as shown in FIG2, the water tank outer shell 30 includes two second outer side walls arranged opposite to each other. Each second outer side wall is provided with one of a guide rib 308 and a guide groove. The guide rib 308 or the guide groove is arranged along a first direction. The water tank assembly 3 can be slidably mounted on the mounting shell 1 by the guidance of the guide rib 308 and the guide groove.

[0124] In this embodiment, guide structures, such as guide ribs 308 or guide grooves, are provided on the outer walls of the opposite sides of the water tank shell 30. Simultaneously, another compatible guide structure can be provided on the cooking cabinet. The cooperation of these two guide structures allows the water tank assembly 3 to be smoothly installed on the cooking cabinet, thus facilitating its assembly and disassembly. Furthermore, the guide ribs 308 or guide grooves are arranged along a first direction, enabling the water tank assembly 3 to be slidably installed onto the cooking cabinet along this first direction.

[0125] The water tank device and steam cooking appliance in this application will be further described below using an oven as an example.

[0126] Among the relevant solutions, the retractable water tank design for ovens mainly falls into two categories: The first type uses a motor to control the retraction of the water tank, but this method is complex, requires electricity, has low reliability, and is costly. The second type uses a spring-loaded mechanism, requiring manual pressing to retract the water tank, but this method is also complex, has low reliability, and is costly.

[0127] This embodiment proposes a telescopic water box solution, which incorporates a limiting module and a spring. The "extension" and "retraction" of the water box are controlled by the combined action of the limiting module and the spring. Thus, pressing the water box allows for both "pop-out" and "push-in" states. Furthermore, in this embodiment, the rebound device is integrated into the water box / shell system, resulting in a simpler system, higher reliability, and lower cost.

[0128] The water tank device 100 and steam cooking appliance 200 provided in the embodiments of this application will be described below with reference to Figures 1 to 10.

[0129] As shown in Figures 4 and 5, an embodiment of this application provides a water tank device 100 for a steam cooking appliance 200. The water tank device 100 includes a water tank assembly 3, which includes a water-containing chamber 300, a water outlet channel 34, and a valve assembly 36. The water outlet channel 34 is connected to the water-containing chamber 300, and the valve assembly 36 is movably installed on the water outlet channel 34 and can move between a first position and a second position. The water outlet channel 34 includes a water outlet 342, and the valve assembly 36 includes a sealing element 39. When the valve assembly 36 is in the first position, the sealing element 39 blocks the water outlet 342, and when the valve assembly 36 is in the second position, the sealing element 39 opens the water outlet 342.

[0130] The water tank device 100 provided according to the embodiments of this application can be specifically used in a steam cooking appliance 200, which may be an oven or similar product. The water tank device 100 specifically includes a water tank assembly 3. The water tank assembly 3 includes a water outlet channel 34 through which water in the water tank assembly 3 can be discharged. A valve assembly 36 is provided within the water outlet channel 34, which can be used to open and close the water outlet channel 34.

[0131] In this application, the sealing element 39 is disposed within the water outlet channel 34, near the water outlet 342. When the water tank assembly 3 is not installed on the product, the valve assembly 36 is in the first position, and the sealing element 39 blocks the water outlet 342, preventing water in the water tank assembly 3 from being discharged through the water outlet channel 34. After the water tank assembly 3 is installed, the valve assembly 36 is in the second position. At this time, the sealing element 39 is positioned away from the water outlet 342, opening the water outlet 342 and connecting it with the water inlet 344. This allows water in the water tank assembly 3 to be discharged through the water outlet channel 34, facilitating the supply of water to the steam cooking appliance 200. In this structure, the seal 39 is installed inside the water outlet channel 34. When the valve assembly 36 closes the water outlet channel 34, the seal 39 can move along the outlet of the water outlet channel 34. In this way, the seal 39 can squeeze out the remaining water in the water outlet channel 34, avoiding the presence of too much water in the water outlet channel 34. This prevents the water tank assembly 3 from leaking when it is removed, thus avoiding any impact on the user experience.

[0132] For example, the water outlet channel 34 can be tilted slightly downward from the inlet to the outlet, which can also reduce the residual water in the water outlet channel 34.

[0133] In any of the above embodiments, as exemplarily shown in Figures 4, 5 and 6, at least a portion of the water outlet channel 34 is located within the water-containing cavity 300. The water outlet channel 34 includes a water inlet 344, which communicates with the water-containing cavity 300 through the water inlet 344. The water inlet 344 is disposed on the side wall of the portion of the water outlet channel 34 located within the water-containing cavity 300.

[0134] In this embodiment, the inlet 344 is located within the water-containing cavity 300 and is situated on the side wall of the outlet channel 34, allowing water in the water tank assembly 3 to flow out through the side wall of the outlet channel 34. In related solutions, the inlet 344 is typically located at the end of the outlet channel 34, thus placing it far from the outlet 342 and avoiding the need to open it. This application places the inlet 344 on the side wall of the outlet channel 34, bringing it closer to the outlet 342. This shortens the movement distance of the seal 39, making it easier for the seal 39 to open the outlet 342 and connect the outlet 342 and inlet 344.

[0135] In any of the above embodiments, as exemplarily shown in Figures 4 and 5, the water tank device 100 further includes: an elastic member 4, installed in the water outlet channel 34, one end of the elastic member 4 being connected to or abutting against the valve assembly 36, and the other end of the elastic member 4 being connected to or abutting against the inner wall of the water outlet channel 34. The elastic member 4 is used to drive the valve assembly 36 to move so that the valve assembly 36 moves from the second position back to the first position.

[0136] In this embodiment, the elastic element 4 is generally a spring. The elastic element 4 is installed between the valve assembly 36 and the inner wall of the water outlet channel 34. Under normal conditions, the elastic element 4 is in a compressed state, and its rebound force can press the seal 39 to close the water outlet 342. When the valve assembly 36 is pushed along the water outlet channel 34, the valve assembly 36 can move the seal 39 and open the water outlet channel 34, allowing water to flow out of the water tank assembly 3. Simultaneously, the elastic element 4 is compressed during this process. Therefore, after the external force on the valve assembly 36 disappears, the elastic element 4 can drive the valve assembly 36 back to its initial position, causing the seal 39 to close the water outlet 342 again. This arrangement, by using the elastic element 4, enables the automatic reset of the valve assembly 36.

[0137] In any of the above embodiments, as exemplarily shown in Figures 4 and 5, the valve assembly 36 further includes: a valve stem 38 slidably mounted on the water outlet channel 34; and a seal 39 mounted on the valve stem 38 and in sealing contact with the inner wall of the water outlet channel 34, wherein the seal 39 can move with the valve stem 38 to open or close the water outlet channel 34.

[0138] In this embodiment, the valve assembly 36 specifically includes a valve stem 38 and a seal 39. The valve stem 38 is slidably mounted within the water outlet channel 34, and the seal 39 is mounted on one end of the valve stem 38 and can move with the valve stem 38. Thus, the water outlet channel 34 can be opened or closed by moving the seal 39. In this structure, the valve stem 38 can drive the seal 39 to move.

[0139] As exemplarily shown in Figures 4 and 5, the elastic element 4 and / or the sealing element 39 are sleeved and mounted on the valve stem 38.

[0140] In this embodiment, the elastic element 4 and the sealing element 39 can be positioned and installed by the valve stem 38, and the elastic element 4 and the sealing element 39 can be guided by the valve stem 38, so as to avoid deformation of the elastic element 4 and the sealing element 39 during movement.

[0141] In any of the above embodiments, as exemplarily shown in Figures 4 and 5, the water outlet channel 34 includes a water outlet 342, and the elastic member 4 is disposed on the side of the sealing member 39 away from the water outlet 342.

[0142] In this embodiment, the seal 39 is positioned close to the outlet 342. To prevent the elastic element 4 from interfering with the operation of the seal 39, the elastic element 4 can be positioned on the side of the seal 39 away from the outlet 342, thereby making the product structure more reasonable.

[0143] In any of the above embodiments, as exemplarily shown in Figures 4 and 5, two first positioning structures 382 are provided on the valve stem 38, the two first positioning structures 382 are spaced apart along the axial direction of the valve stem 38, and the seal 39 is installed between the two first positioning structures 382.

[0144] In this embodiment, the installation position of the seal 39 can be defined by the two first positioning structures 382 to prevent the seal 39 from moving, thereby enabling the seal 39 to reliably seal the outlet 342.

[0145] In any of the above embodiments, as shown in Figures 4 and 5, a second positioning structure 346 is provided on the inner sidewall of the water outlet channel 34, a third positioning structure 384 is provided on the valve stem 38, and the elastic member 4 is abutted and installed between the second positioning structure 346 and the third positioning structure 384.

[0146] In this embodiment, the elastic element 4 is abutted between the valve stem 38 and the water outlet channel 34, so that the position of the elastic element 4 can be accurately defined by the second positioning structure 346 and the third positioning structure 384, thus preventing the elastic element 4 from deforming.

[0147] In any of the above embodiments, as exemplarily shown in Figures 4 and 5, one end of the water outlet channel 34 is provided with a water outlet 342, and the other end of the water outlet channel 34 is provided with a second flange 348. Along the radial direction of the water outlet channel 34, the second flange 348 extends inward from the inner sidewall of the water outlet channel 34, and the second flange 348 forms a through hole 349. The valve stem 38 includes a first rod portion 386 and a second rod portion 388 arranged in a stepped manner. The first rod portion 386 can extend out from the through hole 349, and the diameter of the first rod portion 386 is smaller than the diameter of the second rod portion 388. The elastic member 4 and the sealing member 39 are installed on the second rod portion 388.

[0148] In this application, by providing a through hole 349, the valve stem 38 can extend beyond the water outlet channel 34 during movement, thereby shortening the length of the water outlet channel 34 and avoiding excessive length of the water outlet channel 34, which would waste the internal space of the water tank assembly 3. At the same time, the end of the valve stem 38 near the through hole 349 can be made thinner, so that the valve stem 38 forms a stepped structure, which facilitates the front end of the valve stem 38 extending out of the through hole 349.

[0149] In any of the above embodiments, as exemplarily shown in Figures 1, 4 and 5, the water tank device 100 further includes: a mounting housing 1, including a mounting cavity 12, one end of which is provided with a first mounting port 14, and a push rod 16 is provided on the mounting housing 1; a slot 389 is provided on the valve assembly 36, and the water tank assembly 3 can be inserted into the mounting cavity 12 through the first mounting port 14. When the water tank assembly 3 is located in the mounting cavity 12, a portion of the push rod 16 is inserted into the slot 389 and pushes the valve assembly 36 from the first position to the second position to open the water outlet channel 34.

[0150] In this embodiment, the mounting housing 1 is directly mounted onto the product, and the water tank assembly 3 is detachably mounted on the mounting housing 1. This allows the water tank assembly 3 to be removed separately from the housing 6, facilitating cleaning of the water tank assembly 3. Simultaneously, a push rod 16 can be provided on the mounting housing 1. After the water tank assembly 3 is mounted onto the mounting housing 1, the push rod 16 can be inserted into the water outlet channel 34, thereby pushing the valve assembly 36 to move along the water outlet channel 34, thus opening the water outlet channel 34. After the water tank assembly 3 is removed, the external force exerted by the push rod 16 on the valve assembly 36 disappears, and the valve assembly 36 resets under the rebound force of the elastic element 4, thereby closing the water outlet channel 34 of the water tank assembly 3, preventing water from flowing out of the water outlet channel 34.

[0151] To ensure that the valve assembly 36 and the push rod 16 do not slip, a slot 389 can be provided on the valve assembly 36 so that one end of the push rod 16 can be inserted into the slot 389 to ensure the stability of the valve assembly 36 and the push rod 16 when they are engaged.

[0152] In any of the above embodiments, exemplarily, the water tank assembly 3 has a locked state and an unlocked state within the mounting cavity 12. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can push a portion of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34. When the water tank assembly 3 is in the locked state, the elastic member 4 is in a compressed state. After the water tank assembly 3 is unlocked, the elastic member 4 can extend to push a portion of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34.

[0153] In this embodiment, the water tank assembly 3 can be pressed into or pushed out of the mounting housing 1. After installation, the water tank assembly 3 can be locked inside the mounting housing 1. With the water tank assembly 3 locked, the fit between the water tank assembly 3 and the mounting housing 1 is good, preventing the water tank assembly 3 from easily shaking and thus preventing it from slipping out of the mounting housing 1. When the water tank assembly 3 needs to be added, cleaned, or repaired, it can be unlocked, placing it in the unlocked state. After unlocking, the water tank assembly 3 can be removed from the mounting housing 1.

[0154] When it is necessary to remove the water tank assembly 3 from the cooking unit 6 to add water, the water tank assembly 3 can be unlocked first. After the water tank assembly 3 is unlocked, the external force exerted by the push rod 16 on the valve assembly 36 disappears, and the valve assembly 36 returns to the first position under the action of the elastic member 4. This closes the water outlet channel 34 of the water tank assembly 3, preventing water from flowing out of the water outlet channel 34. At the same time, the water tank assembly 3 is pushed out under the action of the elastic member 4.

[0155] In this structure, the elastic element 4 can push out the water tank assembly 3 and also close the water outlet channel 34 of the valve assembly 36. In other words, in this structure, the elastic element 4 used for the telescopic installation of the water tank assembly 3 and the elastic element 4 required for the valve assembly 36 are the same part. That is, the push-out structure of the water tank assembly 3 and the opening and closing structure of the water outlet 342 of the water tank assembly 3 share a single elastic element 4, thereby simplifying the structure of the product.

[0156] Of course, in other solutions, the elastic element 4 for the telescopic installation of the water tank assembly 3 and the elastic element 4 required for the valve assembly 36 can also be two separate parts.

[0157] In any of the above embodiments, exemplarily, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. After the water tank assembly 3 is unlocked, the elastic member 4 can extend to push a part of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34.

[0158] In these embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can extend to push the water tank assembly 3 out of the mounting housing 1. At the same time, after the water tank assembly 3 extends out of the mounting housing 1, the push rod 16 separates from the water outlet channel 34, and the valve assembly 36 returns to the second position under the action of the elastic member 4, thereby closing the water outlet channel 34.

[0159] Of course, in other solutions, when the water tank assembly 3 is in the locked state, the elastic element 4 can also be set to the extended state.

[0160] In any of the above embodiments, the elastic element 4, by way of example, includes a spring capable of stretching or shortening.

[0161] In these embodiments, the use of a spring that can extend or shorten provides better elasticity to push the water tank assembly 3 out when it needs to be removed from the steam cooking appliance 200. Simultaneously, the spring also allows the valve body assembly to return to its initial installation position to block the water outlet passage 34, thereby preventing leakage of the water tank assembly 3 after it has been removed from the steam cooking appliance 200.

[0162] Of course, the elastic element 4 can also be other structures with a certain degree of elasticity and hardness, such as metal springs or rubber parts.

[0163] In any of the above embodiments, exemplarily, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. After the water tank assembly 3 is unlocked, the elastic member 4 can extend to push a part of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34.

[0164] In these embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can extend to push the water tank assembly 3 out of the mounting housing 1. At the same time, after the water tank assembly 3 extends out of the mounting housing 1, the push rod 16 separates from the water outlet channel 34, and the valve assembly 36 returns to the second position under the action of the elastic member 4, thereby closing the water outlet channel 34.

[0165] Of course, in other solutions, when the water tank assembly 3 is in the locked state, the elastic element 4 can also be set to the extended state.

[0166] In any of the above embodiments, as exemplarily shown in Figures 5 and 9, the elastic element 4 includes a spring capable of stretching or shortening.

[0167] In these embodiments, the use of a spring that can extend or shorten provides better elasticity to push the water tank assembly 3 out when it needs to be removed from the steam cooking appliance 200. Simultaneously, the spring also allows the valve body assembly to return to its initial installation position to block the water outlet passage 34, thereby preventing leakage of the water tank assembly 3 after it has been removed from the steam cooking appliance 200.

[0168] Of course, the elastic element 4 can also be other structures with a certain degree of elasticity and hardness, such as metal springs or rubber parts.

[0169] In any of the above embodiments, as exemplarily shown in Figures 1, 2 and 3, the water tank device 100 further includes: a first limiting member 2, installed on the mounting housing 1; and a second limiting member 32, disposed on the water tank assembly 3. When the water tank assembly 3 is located in the mounting cavity 12, the first limiting member 2 and the second limiting member 32 mutually limit each other to lock the water tank assembly 3. When the water tank assembly 3 is located in the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 can release the limitation between the first limiting member 2 and the second limiting member 32 to unlock the water tank assembly 3.

[0170] In these embodiments, the water tank assembly 3 and the mounting housing 1 can be locked and unlocked by the first limiting member 2 and the second limiting member 32. After the water tank assembly 3 is unlocked, it can be removed from the mounting housing 1 for adding water, cleaning, or repairing / replacing. When the water tank assembly 3 is locked, the fit between the water tank assembly 3 and the mounting housing 1 is good, and the water tank assembly 3 is not easy to shake, thus preventing it from slipping out of the mounting housing 1.

[0171] In this structure, when installing the water tank assembly 3, it is only necessary to push the water tank assembly 3 into the mounting housing 1. When it is necessary to remove the water tank assembly 3, pressing the water tank assembly 3 will release the constraint on the water tank assembly 3 under the rebound action of the elastic member 4, thus allowing the water tank assembly 3 to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or other power equipment for disassembly of the water tank assembly 3, thereby simplifying the structure of the water tank device 100 and reducing its cost. Furthermore, this structure includes a second limiting member 32 on the water tank assembly 3 itself, allowing the elastic member 4 to directly act on the water tank assembly 3, thereby directly limiting the water tank assembly 3 through the first limiting member 2. This makes the limiting of the water tank assembly 3 more reliable and also makes the installation of the water tank assembly 3 within the mounting housing 1 more stable, preventing the water tank assembly 3 from loosening.

[0172] Furthermore, this design integrates the structure that drives the water tank assembly 3 to rebound directly into the water tank assembly 3 and the mounting housing 1, simplifying the overall structure of the water tank device 100 and thus reducing product costs. In this structure, the water tank assembly 3 itself acts as the rebound component, making the pressing and pushing of the water tank assembly 3 more reliable.

[0173] In any of the above embodiments, as exemplarily shown in FIG2 and FIG3, the water tank assembly 3 includes a water tank housing 30, and the second limiting member 32 includes a limiting structure disposed on the water tank housing 30.

[0174] In these embodiments, the water tank assembly 3 includes a water tank housing 30 for holding water. A second limiting member 32 is used to limit the installation position of the water tank assembly 3 within the mounting housing 1. Specifically, the second limiting member 32 can be a limiting structure directly disposed on the water tank housing 30; that is, the second limiting member 32 is part of the water tank assembly 3.

[0175] In any of the above embodiments, for example, the second limiting member 32 and the water tank shell 30 are an integral structure.

[0176] In these embodiments, the second limiting member 32 can be a protruding structure or a recessed structure on the water tank outer shell 30. The second limiting member 32 and the water tank outer shell 30 are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member 32 and the water tank outer shell 30 can be separately provided, and then the second limiting member 32 can be detachably installed on the water tank outer shell 30.

[0177] In any of the above embodiments, exemplarily, as shown in FIG3, the second limiting member 32 includes a guide slide 320, the guide slide 320 including a limiting groove 327; the first limiting member 2 includes a movable member 22, the movable member 22 is mounted on the mounting housing 1, and a portion of the movable member 22 is located within the guide slide 320; when the water tank assembly 3 is installed into the mounting cavity 12, at least a portion of the movable member 22 can move from the first end of the guide slide 320 to the limiting groove 327 and be limited in the limiting groove 327; when the water tank assembly 3 is located in the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 allows at least a portion of the movable member 22 to move towards the second end of the guide slide 320 to separate from the limiting groove 327, thereby unlocking the water tank assembly 3.

[0178] In these embodiments, the first limiting member 2 includes a movable member 22, which may specifically be a rotating member 26 or a sliding member 24. When the water tank assembly 3 is installed in the mounting housing 1 or removed from the mounting housing 1, the movable member 22 can move relative to the guide slide 320. A limiting groove 327 is provided in the guide slide 320, which restricts the movable member 22 to ensure that the water tank assembly 3 can be locked in the third position. Subsequently, when it is necessary to remove the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 to move it inward. This allows the movable member 22 to move again to the position separated from the limiting groove 327, thereby limiting the water tank assembly 3 and placing it in an unlocked state. After the water tank assembly 3 is unlocked, the elastic element 4 can rebound, thereby pushing the water tank assembly 3 to move a certain distance out of the mounting housing 1, so as to realize the automatic ejection of the water tank, making it convenient for the user to disassemble the water tank assembly 3 for cleaning, adding water or maintenance.

[0179] In this configuration, when the water tank assembly 3 is pulled out of the mounting housing 1, the movable part 22 can continue to slide as before, instead of sliding back. This design ensures that the movement path of the movable part 22 is inconsistent when the water tank assembly 3 is inserted into the mounting housing 1 and when it is pulled out of the mounting housing 1, thereby making the locking and unlocking engagement between the movable part 22 and the guide slide 320 more reliable.

[0180] Conversely, when the water tank assembly 3 is unlocked, at least a portion of the movable part 22 can also move back toward the first end of the guide slide 320 until the movable part 22 separates from the limiting groove 327.

[0181] The arrows in Figure 3 illustrate the movement path of the movable part 22.

[0182] In any of the above embodiments, as exemplarily shown in Figures 1, 2 and 3, the movable member 22 includes a slider 24, which is capable of sliding along the guide slide 320 and is confined in the limiting groove 327 when the water tank assembly 3 is located in the mounting cavity 12.

[0183] In these embodiments, the water tank assembly 3 can be inserted and removed by sliding the slider 24 along the guide slide 320. Simultaneously, after the water tank assembly 3 is inserted and installed in place, i.e., when the water tank assembly 3 is installed into the mounting cavity 12, the slider 24 can be better engaged in the limiting groove 327, thereby preventing the slider 24 from sliding and locking the water tank assembly 3. When it is necessary to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inward to retract the limiting groove 327, and the slider 24 slides out of the limiting groove 327 along the second guide surface 324. This releases the limiting engagement between the slider 24 and the limiting groove 327, freeing the water tank assembly 3 and facilitating its removal for heating, adding water, cleaning, or repair / replacement.

[0184] For example, as shown in FIG3, when the water tank assembly 3 is in the locked state, the water tank assembly 3 is located in the third position within the mounting cavity 12; when the water tank assembly 3 is in the unlocked state, the water tank assembly 3 is located in the fourth position within the mounting cavity 12. The guide slide 320 includes: a first guide surface 322; a second guide surface 324, which is set at a first angle to the first guide surface 322; a limiting groove 327 is formed by the first guide surface 322 and the second guide surface 324; and a first slide 326, with the first guide surface 322 disposed at the second end of the first slide 326. The first slide 326 is used to guide the sliding member 24 from the first end of the first slide 326 to the first guide surface 322 during the process of the water tank assembly 3 sliding from the first mounting port 14 into the mounting cavity 12 to the fifth position. When in position five, the water tank assembly 3 is released, and under the action of the elastic member 4, the water tank assembly 3 moves to the outside of the mounting cavity 12 to the third position. The sliding member 24 slides along the first guide surface 322 to the connection between the first guide surface 322 and the second guide surface 324, and is limited to the connection between the first guide surface 322 and the second guide surface 324. The second slide 328, one end of which is connected to the end of the second guide surface 324 away from the first guide surface 322, when the water tank assembly 3 is in the third position in the mounting cavity 12, the water tank assembly 3 is pressed into the mounting cavity 12, and the sliding member 24 can move along the second guide surface 324 into the second slide 328. During the process of the water tank assembly 3 sliding out of the mounting cavity 12 from the first mounting port 14, the sliding member 24 can move along the second slide 328.

[0185] In these embodiments, the first guide surface 322 and the second guide surface 324 can be connected to form a limiting groove 327. After the water tank assembly 3 is installed in place, the sliding member 24 is limited within the limiting groove 327 by the rebound force of the elastic member 4. Thus, through the interaction between the limiting groove 327 and the sliding member 24, the position of the water tank assembly 3 can be limited, preventing the water tank assembly 3 from falling out of the mounting cavity 12 without other external forces. In order to guide the sliding member 24 to enter the limiting groove 327 formed by the first guide surface 322 and the second guide surface 324 normally, a first slide rail 326 is provided. Through the first slide rail 326, the sliding member 24 can be guided to move along a preset trajectory. This ensures that after the water tank assembly 3 is installed in place, the sliding member 24 can just reach the bottom of the limiting groove 327, and the sliding member 24 will not be stuck in advance, which would prevent the water tank assembly 3 from being installed correctly.

[0186] When it is necessary to disassemble the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 so that the other end of the sliding member 24 can move along the second guide surface 324 to separate from the limiting groove 327, thereby releasing the locking of the mounting housing 1 to the water tank assembly 3, so that the water tank assembly 3 can be pulled out from the mounting housing 1, thereby realizing the disassembly of the water tank assembly 3 relative to the mounting housing 1.

[0187] As shown in Figure 3, the guide slide 320 also includes a second slide 328. When the water tank assembly 3 is pulled out from the mounting housing 1, the sliding member 24 can slide along the second slide 328, which can limit the position of the sliding member 24 and guide the water tank assembly 3 to prevent the water tank assembly 3 from shifting and jamming with the mounting housing 1.

[0188] Furthermore, in this structure, when the water tank assembly 3 is inserted into the mounting housing 1 and when the water tank assembly 3 is pulled out of the mounting housing 1, the movement paths of the sliding member 24 are not consistent and form a loop, thereby making the locking and unlocking cooperation between the sliding member 24 and the guide slide 320 more reliable.

[0189] Conversely, the second slide rail 328 may not be provided, and the structure of the first slide rail 326 and the first guide surface 322 may be reasonably designed so that when the water tank assembly 3 is unlocked, the other end of the sliding member 24 can return to the first slide rail 326 along the first guide surface 322.

[0190] In any of the above embodiments, as exemplarily shown in FIG3, the guide slide 320 further includes: an expansion section 329 disposed at the first end of the first slide 326, and a fourth guide surface 3292 disposed on the two inner sidewalls of the expansion section 329. The fourth guide surface 3292 is used to guide the sliding member 24 to move into the first slide 326 during the process of the water tank assembly 3 sliding from the first mounting port 14 into the mounting cavity 12.

[0191] In these embodiments, since the slider 24 has a certain sliding range, its position is not fixed after the water tank assembly 3 is removed. After the water tank assembly 3 is correctly inserted into the mounting housing 1, the slider 24 can always fall within the range of the outward expansion section 329. When the water tank assembly 3 is inserted inward, the slider 24 can be guided into the first slide rail 326 by the fourth guide surface. This structure allows the slider 24 to slide into the first slide rail 326 regardless of its initial position, and then move along a fixed trajectory to the limiting part. Thus, before installing the water tank assembly 3, it is not necessary to reset the slider 24 or specifically determine its position, making the installation of the water tank assembly 3 more convenient.

[0192] Of course, in other solutions, the outer extension section 329 and the fourth guide surface 3292 may not be set. In this case, in order to ensure that the slider 24 can slide into the first slide rail 326, the position of the slider 24 needs to be fixed in advance.

[0193] In any of the above embodiments, as exemplarily shown in FIG1, a limiting hole 10 is provided on the mounting housing 1, and the sliding member 24 is slidably mounted on the limiting hole 10, thereby limiting the sliding range of the sliding member 24.

[0194] In these embodiments, to prevent the slider 24 from sliding excessively, a limiting hole 10 is provided on the mounting housing 1. The limiting hole 10 can limit the sliding range of the slider 24, so that the slider 24 can only move within a predetermined area. This can limit the position of the slider 24 and prevent the slider 24 from moving to other positions and failing to cooperate with the second limiting member 32 on the water tank assembly 3. This ensures that after the water tank assembly 3 is installed on the water tank housing 30, the slider 24 can always cooperate with the second limiting member 32 to lock the water tank assembly 3.

[0195] In any of the above embodiments, as exemplarily shown in FIG1, the movable member 22 includes: a rotating member 26, the first end of the rotating member 26 being rotatably mounted on the outside of the mounting housing 1, the mounting housing 1 being provided with a limiting hole 10, the second end of the rotating member 26 passing through the limiting hole 10 and inserted into the mounting cavity 12, and a sliding member 24 being disposed on the second end of the rotating member 26, the sliding member 24 and the rotating member 26 being an integral structure, or the sliding member 24 and the rotating member 26 being detachably connected.

[0196] In these embodiments, the movable member 22 includes a rotating member 26, and a sliding member 24 is disposed on the rotating member 26. The sliding member 24 can be slidable by rotating the rotating member 26. This structure allows for relatively convenient sliding installation of the sliding member 24.

[0197] The sliding member 24 and the rotating member 26 can be formed as a single part, for example, they can be integrally molded or processed separately and then connected to form a single structure. Alternatively, the sliding member 24 and the rotating member 26 can also be two completely independent parts.

[0198] In any of the above embodiments, as exemplarily shown in FIG1, the water tank device 100 further includes: a press-fitting member 5 disposed outside the mounting housing 1, and at least a portion of the rotating member 26 located between the press-fitting member 5 and the mounting housing 1.

[0199] In these embodiments, the press-fitting member 5 is used to press the rotating member 26 toward the water tank assembly 3. This can limit the position of the rotating member 26 so that the rotating member 26 can abut against the water tank assembly 3, and prevent the rotating member 26 from separating from the water tank assembly 3 during rotation.

[0200] In any of the above embodiments, the press-fitting member 5 is elastic, which allows it to press the rotating member 26 toward the water tank assembly 3.

[0201] In these embodiments, the press-fitting member 5 can be configured as an elastic structure, so that the elastic force of the press-fitting member 5 can press the rotating member 26, so that the other end of the rotating member 26 can always abut against the water tank assembly 3, avoiding the situation where the other end of the rotating member 26 separates from the water tank assembly 3 and the water tank assembly 3 cannot be locked.

[0202] In any of the above embodiments, as exemplarily shown in FIG1, the water tank device 100 further includes a support structure 18 disposed on the outer wall of the mounting housing 1 and supported on the side of the rotating member 26 near the mounting housing 1.

[0203] In this embodiment, in order to limit the height position of the rotating component 26, a support structure 18 is provided on the mounting housing 1 to support the rotating component 26. The support structure 18 can better limit the installation height of the rotating component 26. At the same time, the support structure 18 can also reduce the contact area between the rotating component 26 and the mounting housing 1, thereby reducing the friction between the rotating component 26 and the mounting housing 1.

[0204] As shown in Figure 9, an embodiment of this application provides a steam cooking appliance 200, including the water tank device 100 provided in any of the above embodiments.

[0205] The steam cooking appliance 200 provided according to the embodiments of this application includes the water tank device 100 provided in any of the above embodiments. Therefore, the steam cooking appliance 200 has all the beneficial effects of the water tank device 100 provided in any of the above embodiments, which will not be repeated here.

[0206] In any of the above embodiments, for example, as shown in Figures 9 and 10, the steam cooking appliance 200 includes a housing 6 and a door 7. The housing 6 is provided with a food inlet / outlet 64 at a first end along a first direction. The door 7 is installed at the first end to open or close the food inlet / outlet 64. The water tank shell 30 is installed on the housing 6 and is provided along the first direction. The first installation port 14 is located at the first end of the housing 6 along the first direction.

[0207] The steam cooking appliance 200 provided according to an embodiment of this application includes a cooking chamber and a water tank assembly 3. The cooking chamber generates steam and performs cooking functions. The water tank assembly 3 is detachably installed on the cooking chamber to supply water to the cooking chamber. The cooking chamber includes a body 6 and a door 7. A cooking cavity 62 is provided inside the body 6, and the cooking cavity 62 communicates with a food inlet / outlet 64. The door 7 is installed on the body 6 and is used to open and close the food inlet / outlet 64. The water tank assembly 3 is installed on the side of the body 6 where the door 7 is provided, for example, on the front side of the body 6. The water tank assembly 3 can also be installed on the body 6 along the front side, and it can be pulled out in the front-back direction to achieve disassembly and assembly. Furthermore, the water tank assembly 3 is also placed front-back on the body 6, that is, it is installed horizontally on the body 6, not vertically.

[0208] For example, as shown in Figures 1 to 10, the water tank assembly 3 can be pulled and installed onto the tank body 6 through the first mounting port 14 along a first direction. The water tank assembly 3 includes: a water tank shell 30, which includes a water-containing cavity 300 and a second inlet / outlet 307 communicating with the water-containing cavity 300, the second inlet / outlet 307 being disposed at one end of the water tank shell 30 along the first direction; a cover 302, which is detachably mounted on the water tank shell 30 to open or close the second inlet / outlet 307; and a sealing ring disposed between the water tank shell 30 and the cover 302 to seal the gap between the water tank shell 30 and the cover 302.

[0209] In this embodiment, the water tank assembly 3 specifically includes a water tank shell 30 and a cover 302. The water tank shell 30 is provided with a second inlet / outlet 307, and the cover 302 is detachably mounted on the second inlet / outlet 307 of the water tank shell 30. Meanwhile, to ensure a seal between the water tank shell 30 and the cover 302, a sealing ring is also provided between them. This sealing ring allows for a sealed connection between the two, thereby preventing water leakage from the water tank assembly 3.

[0210] In other oven designs, the water tank assembly typically has a water inlet directly on the side wall of the water tank shell without a removable cover. This makes it difficult to open the water tank and thus inconvenient for cleaning. In this application, a removable cover 302 is provided. This allows for easy cleaning of the water tank assembly 3 by opening the cover 302, improving the convenience of cleaning and ensuring cleanliness. Furthermore, this design allows users to easily inspect the interior of the water tank assembly 3 for dirt and grime, making it easier to detect and clean the assembly promptly. This provides users with greater peace of mind when using the water tank assembly 3.

[0211] The first direction can specifically refer to the front-to-back direction of the cooking cabinet. For example, the water tank assembly 3 can be disassembled and installed from the front side of the cooking cabinet. The cover 302 and the outer shell 30 of the water tank assembly 3 are also assembled along the front-to-back direction. This means that the water tank assembly 3 is installed horizontally on the cooking cabinet, rather than vertically. This reduces the height of the water tank assembly 3 and avoids the entire product being too tall. As a result, the water tank assembly 3 can be installed on the top of the cabinet 6, thus providing conditions for the water tank assembly 3 to be lowered by gravity.

[0212] For example, steam cooking appliance 200 includes an oven. Of course, steam cooking appliance 200 can also be other devices that require a water tank.

[0213] Among them, the sealing element 39 is a sealing ring, and one or more sealing ribs are provided on the outer wall of the sealing ring, and one or more sealing ribs are in sealing contact with the inner wall of the water outlet channel 34.

[0214] In any of the above embodiments, as exemplarily shown in Figures 9 and 10, the steam cooking appliance 200 further includes: a heating device installed on the housing 6 for heating the food in the cooking cavity 62; a water receiving tank 94 installed in the cooking cavity 62 and capable of being heated by the heating device; and a connecting pipe 8 for connecting the water tank device 100 and the water receiving tank 94 to transport water in the water tank device 100 to the water receiving tank 94.

[0215] For example, water in the water tank device 100 can flow through the connecting pipe 8 into the water receiving tank 94 under the action of gravity.

[0216] In the above embodiments, as exemplarily shown in FIG2, the water tank shell 30 includes a first arc-shaped surface arranged along the circumferential direction of the water tank shell 30. The two ends of the first arc-shaped surface arranged along the circumferential direction of the water tank shell 30 are connected by a first outer wall surface. The first outer wall surface includes a first plane 304 and a second arc-shaped surface. An indicator structure 306 is provided on the first plane 304 to indicate the installation direction of the water tank assembly 3. The second arc-shaped surface is located on the side of the first plane 304 near the second inlet / outlet 307 of the water tank shell 30.

[0217] In this embodiment, the water tank outer shell 30 is generally cylindrical, with most of its outer wall surface being curved, such as an arcuate surface. However, at least a portion of the outer wall surface of the water tank outer shell 30 is a first plane 304. The first plane 304 facilitates the installation of the indicator structure 306, the first limiting member of the water tank assembly 3, etc. For example, during processing, a cylindrical water tank can be machined first, and then a portion of the outer wall surface of the cylindrical water tank can be flattened to form the first plane 304.

[0218] In addition, by setting the first plane 304, it is also convenient for users to distinguish the front and back of the water tank shell 30, thereby avoiding incorrect installation of the water tank assembly 3.

[0219] For example, the first outer wall surface also includes a second arc-shaped surface. The second arc-shaped surface is located on the side of the first plane 304 near the second inlet / outlet 307 of the water tank shell 30. That is, the part of the first outer wall surface near the second inlet / outlet 307 is arc-shaped and not flat. This makes the outer wall surface around the entire second inlet / outlet 307 circular, so that the cover 302 can also be set to be circular. This makes the appearance of the entire water tank assembly 3 more beautiful. Especially when the water tank assembly 3 is used in ovens, it can make the shape of the water tank assembly 3 consistent with the knobs and other parts on the oven, thereby improving the overall aesthetics of the oven.

[0220] In the above embodiments, for example, as shown in FIG2, the water tank outer shell 30 includes two second outer side walls arranged opposite to each other. Each second outer side wall is provided with one of a guide rib 308 and a guide groove. The guide rib 308 or the guide groove is arranged along a first direction. The water tank assembly 3 can be slidably mounted on the mounting shell 1 by the guidance of the guide rib 308 and the guide groove.

[0221] In this embodiment, guide structures, such as guide ribs 308 or guide grooves, are provided on the outer walls of the opposite sides of the water tank shell 30. Simultaneously, another compatible guide structure can be provided on the cooking cabinet. The cooperation of these two guide structures allows the water tank assembly 3 to be smoothly installed on the cooking cabinet, thus facilitating its assembly and disassembly. Furthermore, the guide ribs 308 or guide grooves are arranged along a first direction, enabling the water tank assembly 3 to be slidably installed onto the cooking cabinet along this first direction.

[0222] The water tank device 100 is located at the top of the cooking cavity 62 along the height direction of the box body 6, so that the water tank device 100 is installed at a high position, thereby providing conditions for the water tank device 100 to be lowered by gravity.

[0223] In any of the above embodiments, exemplarily, the housing 6 includes an inner liner 60 that forms a cooking cavity 62, and a water tank device 100 is mounted above the inner liner 60. This arrangement allows the water tank device 100 to be mounted relatively high, thereby facilitating the drainage of the water tank assembly using gravity. Furthermore, this arrangement allows for efficient use of the product's height, thereby reducing the product's width and floor space, making it easier to store.

[0224] For example, the housing 6 includes a first part and a second part, with a door 7 installed on the first part along the height direction of the housing 6. The second part is located above the first part, and the water tank assembly 100 is installed on the second part. This allows the water tank assembly to be exposed through the door 7, so that water can be added without opening the door 7, thus facilitating water addition during cooking.

[0225] The water tank device and steam cooking appliance in this application will be further described below using an oven as an example.

[0226] In the relevant solutions, the steam oven includes a water tank. The water tank opening and closing mechanism mainly utilizes the elasticity of the rubber seal and uses a non-elastic structure to deform it and open the water tank. Water is prone to remain in the water tank and cannot be completely drained, and the reliability is low.

[0227] This solution uses a guide rail and inlet / outlet ports on the water tank, and utilizes the different positions of a limiting pin and a sealing ring within the guide rail to control the opening and closing of the water tank. This allows the water tank to be opened and closed by pressing, thus solving the problem of water not being completely drained from the tank.

[0228] In addition, this solution places the inlet and outlet at the lowest point of the water box, so that water can be completely drained when the water box is in the open position.

[0229] The steam cooking appliance provided by the embodiments of this application will now be described with reference to Figures 11 to 22.

[0230] As shown in Figures 11, 12, 18, and 20, an embodiment of this application provides a steam cooking appliance comprising: a housing 6, including a cooking cavity 62, wherein a food inlet / outlet 64 and a first mounting port 14 are provided at a first end along a first direction, the food inlet / outlet 64 being in communication with the cooking cavity 62; a door 7, installed at the first end of the housing 6 to open or close the food inlet / outlet 64; at least one heating device 800, installed on the housing 6 for heating the food inside the cooking cavity 62; and a water collection box 9, installed on the cooking cavity 62. Inside cavity 62, near at least one heating device 800, water in water receiving box 9 can be heated into steam; water tank assembly 3, water tank assembly 3 can be inserted and installed onto box body 6 through first mounting port 14 along first direction, and when water tank assembly 3 is installed on box body 6, water tank assembly 3 is located outside cooking cavity 62, the length direction of water tank assembly 3 is arranged along first direction (i.e. the length extension direction of water tank assembly 3 is consistent with first direction), water tank assembly 3 includes water outlet channel 34, water outlet channel 34 communicates with water receiving box 9.

[0231] The steam cooking appliance provided according to the embodiments of this application can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly, a heating device 800, and a water collection box 9. The housing assembly includes a housing 6 and a door 7. A cooking cavity 62 is provided inside the housing 6 for placing and heating food. The door 7 is used to open and close the cooking cavity 62. The heating device 800 is installed inside the cooking cavity 62 and is capable of heating the food. The water collection box 9 is used to store water and is positioned close to at least one heating device 800, so that the water in the water collection box 9 can be heated into steam by the heating device 800 to humidify and replenish the food in the cooking cavity 62. With this structure, the water collection box 9 can be heated using the existing heating device inside the housing 6, eliminating the need for an additional complex steam generator, thus simplifying the product structure and reducing costs. Furthermore, this structure allows water to be added to the water collection box 9 via the water tank assembly 3, eliminating the need for manual water addition by the user, thereby improving the user experience.

[0232] Meanwhile, the first installation port 14 and the food inlet / outlet 64 are located on the same side, allowing the water tank assembly 3 to be inserted into the housing 6 from the side with the door 7. This enables users to install and remove the water tank assembly 3 from the front of the product, making the operation of the water tank assembly more convenient. Furthermore, the water tank assembly 3 is placed front-to-back on the housing 6, meaning it is installed horizontally, not vertically. This reduces the space occupied by the water tank assembly 3, preventing the entire product from being too tall, and allows the water tank assembly 3 to be installed at the top of the cooking cavity 62, thus providing conditions for the water tank assembly 3 to be lowered by gravity.

[0233] For example, along the height direction of the cabinet 6, the water tank assembly 3 is located above the water receiving box 9 along the height direction of the cooking cabinet 6, so that the water tank assembly 3 is set relatively high and the water receiving box 94 is set relatively low. This allows the water in the water tank assembly 3 to fall under the action of gravity, so that the water can be drained by gravity, making the drainage smoother. This reduces the dependence on water pumps and electrical controls, thereby simplifying the product structure and reducing the product cost.

[0234] In any of the above embodiments, exemplarily, the water in the water tank assembly 3 can fall into the water receiving box 9 under the action of gravity.

[0235] In this embodiment, there is no power equipment between the water tank assembly 3 and the water receiving box 9. The water in the water tank assembly 3 flows into the water receiving box 9 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components, which makes the entire water circuit structure very simple.

[0236] In any of the above embodiments, exemplarily as shown in Figures 11, 13 and 14, the steam cooking appliance further includes: a mounting housing 1, including a mounting cavity 12, one end of which is provided with a first mounting port 14, a water tank assembly 3 being detachably mounted to the mounting housing 1, and the water tank assembly 3 being movable relative to the mounting housing 1 between a locked position and an unlocked position. In the locked position, the water tank assembly 3 is located inside the mounting cavity 12, and in the unlocked position, a portion of the water tank assembly 3 is located outside the mounting cavity 12, and the other portion of the water tank assembly 3 is located inside the mounting cavity 12.

[0237] In these embodiments, the mounting housing 1 is used to support the mounting water tank assembly 3. During installation, the mounting housing 1 can be fixed to the housing 6 of a steam cooking appliance, and then the water tank assembly 3 can be detachably installed inside the mounting housing 1. This allows the water tank assembly 3 to be removed separately, making it convenient to remove the water tank assembly 3 from the product for cleaning and adding water.

[0238] Meanwhile, when the water tank assembly 3 is installed on the mounting housing 1, the water tank assembly 3 can move between an unlocked position and a locked position relative to the mounting housing 1. That is, the water tank assembly 3 has two states on the mounting housing 1. The first is the unlocked state, where the water tank assembly 3 can be removed from the mounting housing 1 for operations such as adding water and cleaning. The second is the locked state, where the water tank assembly 3 is locked and completely contained within the mounting cavity 12, making it impossible to remove from the mounting housing 1. This ensures the stability of the water tank assembly 3 on the mounting housing 1 during product operation.

[0239] When the water tank assembly 3 is in the unlocked position, at least a portion of it is outside the mounting cavity 12, making it easier for the user to remove the water tank assembly 3 and improving the ease of disassembly and assembly. Simultaneously, when the water tank assembly 3 is in the locked position, its outlet is directly above the water storage tank 13, ensuring unobstructed access and allowing water in the water tank assembly 3 to quickly enter the water storage tank 13 under gravity.

[0240] Furthermore, with this structure, during installation, the water tank assembly 3 only needs to be placed inside the mounting housing 1, and during disassembly, the water tank assembly 3 can be directly removed. In other words, no additional pipe connection is required when installing and disassembling the water tank assembly 3, thus ensuring the ease of installation and disassembly of the water tank assembly 3.

[0241] In this design, along the height of the steam cooking appliance, the water outlet 34 is located above the water storage tank 13, which in turn is located above the water collection box 9. This arrangement causes the water outlet 34, drain outlet 11, and water collection box 9 to gradually decrease in height. This allows water to flow sequentially from the water outlet 34 into the water storage tank 13 under gravity, and then from the drain outlet 11 of the water storage tank 13 into the water collection box 9. Thus, the water in the water tank assembly 3 can flow into the water collection box 9 purely by gravity. With this structure, water in the water tank assembly 3 can flow into the water collection box 9 under gravity. That is, there is no power equipment between the water tank assembly 3 and the water receiving box 9. The water in the water tank assembly 3 flows into the water receiving box 9 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components. This reduces the dependence of the water tank assembly 3 on water pumps and electronic control, thereby simplifying the product structure and reducing the product cost.

[0242] In any of the above embodiments, as exemplarily shown in Figures 11, 13 and 14, the mounting cavity 12 includes a first inner wall surface 122 and a second inner wall surface 124. The first inner wall surface 122 is adapted to the shape of the water tank assembly 3, and the second inner wall surface 124 is recessed towards the outside of the mounting cavity 12 to form a water storage tank 13.

[0243] In these embodiments, the water tank assembly 3 is installed inside the mounting housing 1, and the shape and size of a portion of the inner wall of the mounting cavity 12 are consistent with the housing of the water tank assembly 3. This allows the water tank assembly 3 to be installed precisely inside the mounting housing 1, ensuring the compatibility between the water tank assembly 3 and the mounting housing 1. This enables better positioning and installation of the water tank assembly 3 through the mounting housing 1.

[0244] Simultaneously, the lower inner wall of the rear part of the mounting cavity 12 can be recessed downwards to form the required water storage tank 13, thereby facilitating the buffering of the water output from the water tank assembly 3. In this structure, the mounting area of ​​the water tank assembly 3 and the water storage tank 13 are set together, so that the outlet of the water tank assembly 3 and the water storage tank 13 are directly connected. This ensures the fitting accuracy between the water tank assembly 3 and the water storage tank 13, making the water path smoother and preventing the water tank assembly 3 from being misaligned due to improper installation.

[0245] In any of the above embodiments, by way of example, the mounting housing 1 includes a bottom shell and a top cover, the bottom shell and the top cover forming a mounting cavity 12, and a portion of the bottom shell is bent away from the top cover to form a water storage tank 13.

[0246] In these embodiments, the mounting housing 1 is formed by a bottom shell and a top cover. A portion of the bottom shell is bent to form a water storage tank 13; that is, a portion of the bottom shell is sunken to form the water storage tank 13. This method of forming the water storage tank 13 is relatively simple, making the mounting housing 1 easier to manufacture, thereby reducing the manufacturing cost of the mounting housing 1.

[0247] As exemplarily shown in Figures 11, 12 and 18, the water collection box 9 is positioned near the top of the cooking cavity 62.

[0248] In this embodiment, the water collection box 9 is located at or near the top of the cooking cavity 62, thus positioning it relatively high. When using a steam cooking appliance, ingredients are typically placed in the lower middle part of the cooking cavity 62, leaving the top of the cavity generally empty. This application, by placing the water collection box 9 near the top of the cooking cavity 62, fully utilizes the space at the top of the cavity, improving its space utilization rate, and ensuring that the placement of the water collection box 9 does not affect the actual usable volume of the cooking cavity 62.

[0249] In any of the above embodiments, the water receiving box 9 is detachably installed within the cooking cavity 62. The detachment of the water receiving box 9 facilitates its disassembly and cleaning.

[0250] For example, the water collection box 9 is positioned near the top edge of the cooking cavity 62. This arrangement makes the water collection box 9 less likely to affect the volume utilization of the cooking cavity 62, thereby further making full use of the space at the top of the cooking cavity 62 and improving the space utilization rate of the cooking cavity 62.

[0251] In any of the above embodiments, as exemplarily shown in Figures 12, 16, 17 and 18, the steam cooking appliance further includes: a first support 500 installed inside the cooking cavity 62, and a water collection box 9 detachably installed on the first support 500.

[0252] In this embodiment, a first bracket 500 is installed inside the housing 6. The first bracket 500 is mounted on the inner wall of the housing 6. For example, the first bracket 500 can be installed on the housing 6 by means of screws or clips. The water collection box 9 is mounted on the first bracket 500, which makes the installation and removal of the water collection box 9 more convenient. At the same time, the first bracket 500 is mounted on the inner wall of the housing 6, so that the water collection box 9 can be installed on the top edge of the cooking cavity 62. This makes it less likely that the water collection box 9 will affect the volume of the cooking cavity 62, thereby further making full use of the space at the top of the cooking cavity 62 and improving the space utilization rate of the cooking cavity 62.

[0253] In any of the above embodiments, as exemplarily shown in Figures 12, 16, 17, and 18, the steam cooking appliance further includes: two second supports 600, respectively disposed on two inner sidewalls of the housing 6 that are opposite each other along the width direction, for supporting the food carrier 400; wherein, a first support 500 is installed on the top of one of the second supports 600, and the second support 600 is provided with a plurality of support parts 610, which are spaced apart along the height direction of the housing 6, and the two second supports 600 can install the food carrier 400 at multiple positions in the height direction through the plurality of support parts 610.

[0254] In this embodiment, the second bracket 600 can be used to support and install the food carrier 400, such as the baking tray 410, and adjust the installation height of the food carrier 400. The first bracket 500 is installed on top of the second bracket 600. In this structure, the water receiving box 9 and the first bracket 500 are directly installed on the support bracket of the food carrier 400, such as the baking tray 410. This allows the installation of the water receiving box 9 to be achieved using the existing brackets within the housing 6, thereby simplifying the overall product structure and reducing the overall product cost.

[0255] The first support 500 and the second support 600 are integral structures. For example, the first support 500 and the second support 600 can be integrally processed and formed. In this case, the first support 500 and the second support 600 are combined into one support. Alternatively, the first support 500 and the second support 600 are separate structures that can be detached or integrally connected.

[0256] Alternatively, the first bracket 500 can be installed on only one of the second brackets 600. In this case, the first bracket 500 and the second bracket 600 can be set separately, and then the first bracket 500 and the second bracket 600 can be detachably connected or connected as a whole. In other solutions, the first bracket 500 can be installed on both second brackets 600. In this case, the brackets on both sides of the cooking cavity 62 are consistent.

[0257] The structure and shape of the first support 500 and the second support 600 can be the same or slightly different.

[0258] In any of the above embodiments, as exemplarily shown in Figures 15 and 16, a first flange 92 is provided around the water receiving box 9 in the circumferential direction, and the first flange 92 extends from the inner side of the water receiving box 9 to the outer side; the first bracket 500 includes a support bar 510, and the water receiving box 9 is mounted on the support bar 510 through the first flange 92.

[0259] In this embodiment, the first flange 92 enables the positioning and installation of the water receiving box 9. To ensure the installation of the first bracket 500 with the water receiving box 9, a support strip 510 is provided on the first bracket 500. The support strip 510 can be supported at the bottom of the first flange 92 to support the water receiving box 9. To ensure the installation stability of the water receiving box 9, the shape of the support strip 510 can be adapted to the outer wall of the water receiving box 9, and the length of the support strip 510 can be set with reference to the outer periphery of the water receiving box 9.

[0260] For example, when the water receiving box 9 is elongated, the support strip 510 can cover three sides of the water receiving box 9 to ensure the stability of the support strip 510 in supporting the water receiving box 9. When the water receiving box 9 is circular or near-circular, the support strip 510 can cover more than three-quarters of the circumference of the water receiving box 9.

[0261] As exemplarily shown in Figures 15, 16, and 18, the water receiving box 9 has a long, narrow structure and is arranged along the front-to-back direction of the housing 6. The long, narrow structure of the water receiving box 9 reduces the width it occupies, thereby improving the space utilization of the cooking cavity 62.

[0262] For example, the water receiving box 9 has a long strip structure, and the support strip 510 supports three sides of the water receiving box 9. This ensures the installation stability of the water receiving box 9.

[0263] As exemplarily shown in Figures 12 and 18, the heating device 800 includes a heating element 810 mounted on the top of the housing 6.

[0264] In this embodiment, the heating device 800 can be of various heating forms, such as infrared heating, thermal radiation heating, or electromagnetic heating. For example, a heating element 810 can be installed on the top of the cooking cavity 62 to heat the food. At this time, the water tank assembly 3 can be installed on the outer top of the housing 6, and the water receiving box 9 can be positioned close to the top of the cooking cavity 62, so that the heating element 810 can be used to heat the water in the water receiving box 9 into steam.

[0265] In any of the above embodiments, exemplarily as shown in Figures 12 and 15, the water receiving box 9 includes a water receiving trough 94, and the steam cooking appliance further includes: a connector 700 disposed in the housing 6, with the outlet end of the connector 700 located above the water receiving trough 94 along the height direction of the housing 6, and the water receiving trough 94 capable of receiving water from the connector 700; and a connecting pipe 8 for connecting the water tank assembly 3 and the connector 700, wherein the outlet end of the connector 700 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62.

[0266] In any of the above embodiments, exemplarily, the water receiving box 9 includes a water receiving trough 94, and the steam cooking appliance further includes: a connector 700 disposed in the housing 6, with the outlet end of the connector 700 located above the water receiving trough 94 along the height direction of the housing 6; and a connecting pipe 8 for connecting the water tank assembly 3 and the connector 700, so as to transport water in the water tank assembly 3 to the water receiving trough 94 through the connecting pipe 8 and the connector 700. Exemplarily, the outlet end of the connector 700 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62.

[0267] In this embodiment, the water receiving box 9 is an open-topped water receiving trough 94. A connector 700 is installed on the housing 6, positioned above the water receiving trough 94, allowing water in the connector 700 to fall into the water receiving trough 94 under gravity. Simultaneously, steam generated by heating in the water receiving trough 94 can be directly discharged from the opening. This structure simplifies the design of the water receiving box 9, facilitating its processing and cleaning.

[0268] Meanwhile, to ensure water flow between the water tank assembly 3 and the water receiving box 9, a connector 700 is provided on the water receiving box 9 or the tank body 6, and a connecting pipe 8 is installed on the tank body 6. Water in the water tank assembly 3 can be transported to the water receiving box 9 through the connecting pipe 8 and the connector 700. This structure, by directly transporting water to the water receiving box 9 through the connecting pipe 8, guides the water and prevents it from flowing to other places. It also prevents water from falling directly from a height, thereby reducing water flow noise.

[0269] The outlet end of connector 700 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62. This guides the water flowing out of the outlet end of connector 700 away from the inner wall of the cooking cavity 62, preventing it from flowing along the inner wall. This allows the water flowing out of the outlet end of connector 700 to flow into the water collection box 9. This prevents water from flowing to other parts of the cooking cavity 62 and affecting the cooking of the product when water is supplied to the water collection box 9. This also ensures that there is no obvious turbulence at the outlet of connector 700, thus ensuring the cleanliness of other parts of the cooking cavity 62 and preventing them from getting wet.

[0270] For example, the water tank assembly 3 includes a cylindrical water tank.

[0271] In this embodiment, at least the outer wall surface of the water tank shell 30 is an arc-shaped surface, and the top cover is cylindrical. That is, the water tank shell 30 is not square, but roughly cylindrical.

[0272] In any of the above embodiments, for example, as shown in FIG12, the first mounting port 14 is a circular hole, and / or as shown in FIG19 and FIG20, at least a portion of the water tank assembly 3 is cylindrical.

[0273] In this embodiment, when the water tank assembly 3 is installed on the housing 6, the end of the water tank assembly 3 near the first mounting opening 14 is flush with the outer surface of the housing 6. This ensures the overall appearance of the product and prevents the water tank assembly 3 from protruding from the housing 6. Simultaneously, the first mounting opening 14 is circular, and the water tank assembly 3 is cylindrical overall. In specific design, a portion of the water tank assembly 3 can be cylindrical, while another portion can be machined with positioning surfaces, etc., to form an overall cylindrical structure. Of course, in other solutions, the entire water tank assembly 3 can also be cylindrical, with additional guide structures, etc., added to the cylindrical structure. Making the entire water tank assembly 3 cylindrical, especially with the end near the first mounting opening 14 being circular, makes the overall appearance of the water tank assembly 3 more aesthetically pleasing. Especially when the water tank assembly 3 is used in ovens, it allows the shape of the water tank assembly 3 to match the knobs and other knobs on the oven, thus improving the overall aesthetics of the oven.

[0274] In any of the above embodiments, for example, when the water tank assembly 3 is installed on the tank body 6, one end of the water tank assembly 3 near the first mounting port 14 is flush with the outer surface of the tank body 6, or is located outside the tank body 6.

[0275] In this embodiment, after the water tank assembly 3 is installed on the tank body 6, the outer end of the water tank assembly 3, that is, the end near the first mounting port 14, is flush with or exposed on the outer surface of the tank body 6. This can avoid forming obvious holes in the tank body 6, thereby making the tank body 6 more aesthetically pleasing.

[0276] In any of the above embodiments, as exemplarily shown in Figures 12 and 20, a portion of the water tank assembly 3 is cylindrical, a portion of the outer wall surface of another portion of the water tank assembly 3 is an arc surface, and a portion of the outer wall surface of another portion of the water tank assembly 3 is a first plane 304.

[0277] In this embodiment, the water tank outer shell 30 is generally cylindrical, with most of its outer wall surface being curved, such as an arc surface. This makes the water tank assembly 3 appear circular overall, ensuring that the shape of the circular knob on the water tank assembly 3 and the tank body 6 is consistent, thus making the overall appearance of the product more harmonious and aesthetically pleasing. Simultaneously, at least a portion of the outer wall surface of the water tank outer shell 30 is a first plane 304. The first plane 304 facilitates the installation of indicator structures, first limiting members 2, etc. For example, during processing, a cylindrical water tank can be machined first, and then a portion of the outer wall surface of the cylindrical water tank can be flattened to form the first plane 304.

[0278] In addition, by setting the first plane 304, it is also convenient for users to distinguish the front and back of the water tank shell 30, thereby avoiding incorrect installation of the water tank assembly 3.

[0279] In any of the above embodiments, exemplarily, the cylindrical water tank includes a first inlet and outlet water outlet, which are disposed on the side wall of the cylindrical water tank.

[0280] In this embodiment, water can be added to the cylindrical water tank through the first inlet and outlet. When the water tank assembly 3 is installed on the tank body 6, the first inlet and outlet are located on the upper side wall of the cylindrical water tank. By placing the first inlet and outlet on the upper side wall of the cylindrical water tank, water will not leak from the water tank assembly 3 after installation.

[0281] In any of the above embodiments, as exemplarily shown in Figures 11, 13 and 14, the water tank assembly 3 further includes a water outlet channel 34, and the mounting housing 1 further includes a water storage tank 13 and a drain outlet 11 that are interconnected. The water storage tank 13 is provided corresponding to the water outlet channel 34 and is used to receive water from the water outlet channel 34. The drain outlet 11 is connected to the water receiving box 9, and the water in the water storage tank 13 can be discharged into the water receiving box 9 through the drain outlet 11.

[0282] In this embodiment, a water storage tank 13 is provided on the housing 1. After the water tank assembly 3 is installed, the water outlet channel 34 of the water tank assembly 3 is positioned corresponding to the water storage tank 13. Water discharged from the water outlet channel 34 can first enter the water storage tank 13 and then be discharged from the water storage tank 13 into the water receiving box 9. This design, with the water storage tank 13 provided for the water tank assembly 3, creates a large buffer area at the water outlet of the water tank assembly 3. When the water flow in the water tank assembly 3 is large or rapid, the water can be stored in the storage chamber to buffer the impact of the falling water, allowing the water to enter the cooking chamber 62 at a relatively stable flow rate. This avoids water splashing when the water flow is large and enters the water receiving box 9. Furthermore, the buffering effect of the water flow by the water storage tank 13 also prevents water from overflowing into other parts of the product, or even overflowing from the front end of the water tank assembly 3, when the water flow is obstructed.

[0283] For example, when water is added directly to the water tank assembly 3 without removing it, the water flow rate is very high. This water flow has a strong impact force, which can easily cause instability in the water flow output from the water tank assembly 3, leading to splashing. Furthermore, it can also cause water to overflow because it cannot drain quickly enough. This application effectively solves the problems of unstable water flow from the water tank assembly 3 causing splashing and overflow by additionally setting a water storage tank 13 at the water outlet channel 34.

[0284] Furthermore, this structure, due to the installation housing 1, allows the installation housing 1 to be connected to the water receiving box 9, etc., during use. The water tank assembly 3 does not need to be directly connected to the water receiving box 9, etc. This means that no pipe connection is required when installing and disassembling the water tank assembly 3, making it very convenient to disassemble and assemble the water tank assembly 3, and thus making it easier to remove the water tank assembly 3 for cleaning or adding water.

[0285] In any of the above embodiments, for example, as shown in FIG13, the inner bottom wall of the water storage tank 13 gradually decreases from a position away from the drain outlet 11 to a position close to the drain outlet 11.

[0286] In this embodiment, after water is added to the water tank assembly 3, the water in the water tank assembly 3 can enter the water storage tank 13 through the water outlet 34. The inner bottom wall of the water storage tank 13 gradually decreases from other positions to the drain outlet 11. In this way, when there is less water in the water storage tank 13, the water can gather at the water outlet of the water storage tank 13, making it easier to drain the water in the water storage tank 13. This can prevent water from remaining in the water storage tank 13 and reduce the amount of residual water in the water storage tank 13.

[0287] In any of the above embodiments, as exemplarily shown in Figures 19, 20, 21, and 22, the steam cooking appliance further includes: a first limiting member 2, installed on the mounting housing 1; a second limiting member 32, disposed on the water tank assembly 3; when the water tank assembly 3 is in the locked position within the mounting cavity 12, the first limiting member 2 and the second limiting member 32 mutually limit each other to lock the water tank assembly 3; when the water tank assembly 3 is in the locked position within the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 can release the limitation between the first limiting member 2 and the second limiting member 32 to unlock the water tank assembly 3; and an elastic member 4, installed between the water tank assembly 3 and the mounting housing 1, for moving the water tank assembly 3 to the unlocked position after the water tank assembly 3 is unlocked.

[0288] In these embodiments, the water tank assembly 3 and the mounting housing 1 can be locked and unlocked by the first limiting member 2 and the second limiting member 32. After the water tank assembly 3 is unlocked, it can be removed from the mounting housing 1 for adding water, cleaning, or repair / replacement. When the water tank assembly 3 is locked, the fit between it and the mounting housing 1 is good, preventing the water tank assembly 3 from shaking and thus preventing it from slipping out of the mounting housing 1. Furthermore, with this structure, when installing the water tank assembly 3, it is only necessary to push it into the mounting housing 1. When it needs to be removed, pressing the water tank assembly 3 releases the constraint under the rebound of the elastic member 4, allowing the water tank assembly 3 to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or ejection device for disassembly of the water tank assembly 3, simplifying its structure and reducing its cost. In addition, in this structure, the water tank assembly 3 itself is provided with a second limiting member 32, so that the elastic member 4 can directly act on the water tank assembly 3 itself, thereby limiting the water tank assembly 3 directly through the first limiting member 2, making the limiting of the water tank assembly 3 more reliable, and also making the water tank assembly 3 more securely installed in the mounting shell 1, so that the water tank assembly 3 is not easy to loosen.

[0289] Furthermore, this design integrates the structure that drives the water tank assembly 3 to rebound directly into the water tank assembly 3 and the mounting housing 1, simplifying the overall structure of the water tank assembly 3 and thus reducing product costs. In addition, this structure uses the water tank assembly 3 itself as the rebound component, making the pressing and ejection of the water tank assembly 3 more reliable.

[0290] In these embodiments, the water tank assembly 3 includes a water tank housing 30 for holding water. A second limiting member 32 is used to limit the position of the water tank assembly 3 within the mounting housing 1.

[0291] For example, as shown in Figures 19 and 21, the second limiting member 32 and the water tank shell 30 are an integral structure.

[0292] In these embodiments, the second limiting member 32 can be a protruding structure or a recessed structure on the water tank outer shell 30. The second limiting member 32 and the water tank outer shell 30 are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member 32 and the water tank outer shell 30 can be separately provided, and then the second limiting member 32 can be detachably installed on the water tank outer shell 30.

[0293] In any of the above embodiments, exemplarily, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. After the water tank assembly 3 is unlocked, the elastic member 4 can extend to push a part of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34.

[0294] In these embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can extend to push the water tank assembly 3 out of the mounting housing 1. At the same time, after the water tank assembly 3 extends out of the mounting housing 1, the push rod 16 separates from the water outlet channel 34, and the valve assembly 36 returns to the second position under the action of the elastic member 4, thereby closing the water outlet channel 34.

[0295] In any of the above embodiments, as exemplarily shown in Figures 13 and 19, the water tank assembly 3 further includes: a valve assembly 36, installed at the water outlet channel 34 of the water tank assembly 3, capable of operating between a first position and a second position; a push rod 16 is provided on the mounting housing 1. When the water tank assembly 3 is in the locked position, the push rod 16 is inserted into the water outlet channel 34 and the valve assembly 36 is in the first position to open the water outlet channel 34. When the water tank assembly 3 is in the unlocked position or after the water tank assembly 3 is separated from the mounting housing 1, the valve assembly 36 moves from the first position to the second position under the action of the elastic member 4 to close the water outlet channel 34.

[0296] In this embodiment, after the water tank assembly 3 is correctly installed on the mounting housing 1, the valve assembly 36 can be lifted by the push rod 16, thereby opening the water outlet channel 34. After the water tank assembly 3 is unlocked or removed, the valve assembly 36 can automatically return to the second position under the action of the elastic element 4 to close the water outlet channel 34. This makes the opening and closing of the water tank assembly 3 very convenient. This structure can achieve the opening and closing of the water tank assembly 3 purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly 3 more durable. At the same time, in this structure, the elastic element 4 used for the telescopic installation of the water tank assembly 3 and the elastic element 4 required for the valve assembly 36 are the same part, that is, the pop-out structure of the water tank assembly 3 and the opening and closing structure of the water outlet of the water tank assembly 3 share a single elastic element 4, thereby simplifying the product structure.

[0297] As exemplarily shown in Figures 13 and 19, the valve assembly 36 includes: a valve stem 38 slidably mounted within the outlet channel 34; and a seal 39 mounted on the valve stem 38 and capable of moving with the valve stem 38 to open or seal the outlet channel 34.

[0298] For example, as shown in FIG13, the water outlet channel 34 includes a water outlet. When the valve assembly 36 is in the first position, the seal 39 blocks the water outlet. When the valve assembly 36 is in the second position, the seal 39 opens the water outlet.

[0299] In this embodiment, the seal 39 is disposed within the water outlet channel 34, near the water outlet. When the water tank assembly 3 is not installed on the product, the valve assembly 36 is in the first position, and the seal 39 blocks the water outlet, preventing water in the water tank assembly 3 from draining through the water outlet channel 34. After the water tank assembly 3 is installed, the valve assembly 36 is in the second position. At this time, the seal 39 is positioned away from the water outlet and opens the water outlet, connecting the water outlet and the water inlet. This allows water in the water tank assembly 3 to drain through the water outlet channel 34, facilitating water supply to the steam cooking appliance. With this structure, the seal 39, installed within the water outlet channel 34, can move along the outlet of the water outlet channel 34 when the valve assembly 36 closes the water outlet channel 34. This allows the seal 39 to squeeze out any remaining water in the water outlet channel 34, preventing excessive water residue. This also prevents leakage when the water tank assembly 3 is removed, thus avoiding any impact on the user experience.

[0300] Of course, in other solutions, as shown in Figure 19, the seal 39 can also be provided at the water inlet to open or block the water inlet.

[0301] In any of the above embodiments, exemplarily as shown in FIG13, at least a portion of the water outlet channel 34 is located within the water receiving cavity 300. The water outlet channel 34 includes a water inlet, and the water outlet channel 34 communicates with the water receiving cavity 300 through the water inlet. The water inlet is disposed on the side wall of the portion of the water outlet channel 34 located within the water receiving cavity 300. This arrangement allows the water inlet to be closer to the water outlet, thereby shortening the movement distance of the seal 39 and making it easier for the seal 39 to open the water outlet and connect the water outlet and the water inlet.

[0302] In any of the above embodiments, exemplarily as shown in Figures 13 and 19, the water tank assembly 3 includes: a water tank shell 30, the water tank shell 30 including a water-containing cavity 300 and a second inlet / outlet 307 communicating with the water-containing cavity 300, the second inlet / outlet 307 being disposed at one end of the water tank shell 30 along a first direction; a cover 302, detachably mounted on the water tank shell 30 to open or close the second inlet / outlet 307; and a sealing ring 309 disposed between the water tank shell 30 and the cover 302 to seal the gap between the water tank shell 30 and the cover 302.

[0303] The water tank assembly 3 specifically includes a water tank shell 30 and a cover 302. The water tank shell 30 is provided with a second inlet / outlet 307, and the cover 302 is detachably mounted on the second inlet / outlet 307 of the water tank shell 30. To ensure a seal between the water tank shell 30 and the cover 302, a sealing ring 309 is provided between them. This sealing ring 309 ensures a sealed connection between the two, thereby preventing water leakage from the water tank assembly 3.

[0304] In other oven designs, the water tank assembly typically has a water inlet directly on the side wall of the water tank shell without a removable cover. This makes it difficult to open the water tank and thus inconvenient for cleaning. In this application, a removable cover 302 is provided. This allows for easy cleaning of the water tank assembly 3 by opening the cover 302, improving the convenience of cleaning and ensuring cleanliness. Furthermore, this design allows users to easily inspect the interior of the water tank assembly 3 for dirt and grime, making it easier to detect and clean the assembly promptly. This provides users with greater peace of mind when using the water tank assembly 3.

[0305] Specifically, the first direction can be the front-to-back direction of the tank body 6. In this case, the water tank assembly 3 can be disassembled and assembled from the front side of the tank body 6. The cover 302 and the outer shell 30 of the water tank assembly 3 are also assembled along the front-to-back direction. This means that the water tank assembly 3 is installed horizontally on the tank body 6, rather than vertically. This reduces the space occupied by the height of the water tank assembly 3, preventing the entire product from becoming too tall.

[0306] In any of the above embodiments, as exemplarily shown in FIG12, the housing 6 includes an inner liner 60, which forms a cooking cavity 62, and a water tank assembly 3 is installed above the inner liner 60.

[0307] In this embodiment, the water tank assembly 3 is installed relatively high to facilitate water discharge using gravity. Furthermore, this design allows for efficient use of the product's height, thereby reducing its width and footprint, and making it easier to store.

[0308] In any of the above embodiments, for example, as shown in FIG12, the housing 6 includes a first part and a second part, the door 7 is installed on the first part, the second part is located above the first part along the height direction of the housing 6, the first mounting port 14 is provided on the second part, and the water tank assembly 3 is detachably installed on the second part.

[0309] In this embodiment, the water tank assembly 3 and the door 7 are installed in different areas of the box 6, so that the door 7 and the water tank assembly 3 are installed in different areas of the box 6, and the water tank assembly 3 can be exposed on the door 7. Therefore, when adding water, the door 7 does not need to be opened, which makes it convenient to add water during the cooking process.

[0310] Among them, the sealing element 39 is a sealing ring 309, and one or more sealing ribs are provided on the outer side wall of the sealing ring 309, and one or more sealing ribs are in sealing contact with the inner side wall of the water outlet channel 34.

[0311] The heating device 800 is located on the top of the cooking cavity 62. It can heat the water tank 9 and also heat the food in the cooking cavity 62. In other words, this application uses the heat source on the existing product for heating, without the need to set up a separate heating structure for the water tank. This simplifies the product structure, reduces the cost of product upgrades, and makes it easier for the product to be promoted and updated.

[0312] In order to ensure the overall heating effect of the steam cooking appliance, other heating devices 800 can also be set. For example, additional heating devices 800 can be set at the bottom or sides of the cooking cavity 62 to ensure the heating effect of the entire product on the food.

[0313] In any of the above embodiments, exemplarily as shown in Figures 19, 21, and 22, the second limiting member 32 includes a guide slide 320, which includes a limiting groove; the first limiting member 2 includes a movable member 22, which is mounted on the mounting housing 1, and a portion of the movable member 22 is located within the guide slide 320; when the water tank assembly 3 is installed into the mounting cavity 12, at least a portion of the movable member 22 can move from the first end of the guide slide 320 to the limiting groove and be limited within the limiting groove; when the water tank assembly 3 is located within the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 allows at least a portion of the movable member 22 to move towards the second end of the guide slide 320 until it separates from the limiting groove, thereby unlocking the water tank assembly 3.

[0314] In these embodiments, the first limiting member 2 includes a movable member 22, which can be a rotating member or a sliding member. When the water tank assembly 3 is installed inside the mounting housing 1 or removed from the mounting housing 1, the movable member 22 can move relative to the guide slide 320. A limiting groove is provided in the guide slide 320, which restricts the movable member 22 to ensure that the water tank assembly 3 can be locked in the third position. Subsequently, when it is necessary to remove the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 to move inward. This allows the movable member 22 to move again to the position separated from the limiting groove, thus limiting the water tank assembly 3 and placing it in an unlocked state. After the water tank assembly 3 is unlocked, the elastic member 4 can rebound, pushing the water tank assembly 3 a distance outward from the mounting housing 1, thereby automatically ejecting the water tank. This facilitates subsequent disassembly of the water tank assembly 3 for cleaning, adding water, or maintenance.

[0315] In this configuration, when the water tank assembly 3 is pulled out of the mounting housing 1, the movable part 22 can continue to slide as before, instead of sliding back. This design ensures that the movement path of the movable part 22 is inconsistent when the water tank assembly 3 is inserted into the mounting housing 1 and when it is pulled out of the mounting housing 1, thereby making the locking and unlocking engagement between the movable part 22 and the guide slide 320 more reliable.

[0316] Conversely, when the water tank assembly 3 is unlocked, at least a portion of the movable part 22 can also move back toward the first end of the guide slide 320 until the movable part 22 separates from the limiting groove.

[0317] In any of the above embodiments, as exemplarily shown in FIG20, the movable member 22 includes a slider that can slide along the guide slide 320 and be confined in the limiting groove when the water tank assembly 3 is located in the mounting cavity 12.

[0318] In these embodiments, the movable component 22 includes a sliding component. The sliding component slides along the guide rail 320, allowing the water tank assembly 3 to be inserted and removed. Simultaneously, after the water tank assembly 3 is inserted and installed in place, i.e., when the water tank assembly 3 is installed into the mounting cavity 12, the sliding component can be better engaged in the limiting groove, thus preventing the sliding component from sliding and locking the water tank assembly 3. When it is necessary to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inward to retract the limiting groove, allowing the sliding component to slide out of the limiting groove along the second guide surface. This releases the limiting fit between the sliding component and the limiting groove, freeing the water tank assembly 3 and facilitating its removal for heating, adding water, cleaning, or repair / replacement.

[0319] As shown in Figure 11, the first end of the tank body 6 along the first direction is provided with a second mounting port 66. The second mounting port 66 is provided in correspondence with the first mounting port 14 and avoids the first mounting port 14 so that the water tank assembly 3 can be inserted into the mounting shell 1 from the front side of the tank body 6.

[0320] As shown in Figure 14, the water tank assembly 3, the mounting housing 1, the connecting pipe 8, the connector 700, and the water receiving trough 94 constitute the water circuit assembly of this application.

[0321] In any of the above embodiments, the steam cooking appliance, exemplarily, includes an oven and / or a steamer. Of course, the steam cooking appliance can also be other devices that require a water tank.

[0322] In Figure 22, the arrows indicate the movement trajectory of the movable part 22 within the guide slide 320.

[0323] The steam cooking appliance provided by the embodiments of this application will now be described with reference to Figures 11 to 22.

[0324] As shown in Figures 11, 12 and 18, an embodiment of this application provides a steam cooking appliance, including: a housing 6, the housing 6 including a cooking cavity 62; a water collection box 9, installed inside the cooking cavity 62 and disposed near the top of the cooking cavity 62; and a heating device 800, installed inside the cooking cavity 62 and located at the top of the cooking cavity 62, for heating the water collection box 9 to heat the water in the water collection box 9 into steam.

[0325] The steam cooking appliance provided according to the embodiments of this application can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly, a heating device 800, and a water collection box 9. The housing assembly includes a housing body 6 and a door 7. A cooking cavity 62 is provided inside the housing body 6, which is used to place and heat food ingredients. The heating device 800 is installed on the top of the cooking cavity 62 and can heat the water collection box 9. The water collection box 9 is used to store water, and the water in the water collection box 9 can be heated into steam by the heating device 800 to humidify and replenish the food ingredients in the cooking cavity 62.

[0326] In this design, the water collection box 9 is positioned at or near the top of the cooking cavity 62, thus placing it relatively high. When using a steam cooking appliance, food is typically placed in the lower middle part of the cooking cavity 62, leaving the top generally empty. This application's placement of the water collection box 9 near the top of the cooking cavity 62 fully utilizes the space at the top, improving the space utilization rate of the cooking cavity 62, and ensuring that the placement of the water collection box 9 does not affect the actual usable volume of the cooking cavity 62.

[0327] In any of the above embodiments, the water receiving box 9 is detachably installed within the cooking cavity 62. The detachment of the water receiving box 9 facilitates its disassembly and cleaning.

[0328] In any of the above embodiments, as exemplarily shown in Figures 12 and 18, the water collection box 9 is positioned near the top edge of the cooking cavity 62. This arrangement makes the water collection box 9 less likely to affect the volume utilization of the cooking cavity 62, thereby further making full use of the space at the top of the cooking cavity 62 and improving the space utilization rate of the cooking cavity 62.

[0329] In any of the above embodiments, as exemplarily shown in Figures 12, 16, 17 and 18, the steam cooking appliance further includes: a first support 500 installed inside the cooking cavity 62, and a water collection box 9 detachably installed on the first support 500.

[0330] In this embodiment, a first bracket 500 is installed inside the housing 6. The first bracket 500 is mounted on the inner wall of the housing 6. For example, the first bracket 500 can be installed on the housing 6 by means of screws or clips. The water collection box 9 is mounted on the first bracket 500, which makes the installation and removal of the water collection box 9 more convenient. At the same time, the first bracket 500 is mounted on the inner wall of the housing 6, so that the water collection box 9 can be installed on the top edge of the cooking cavity 62. This makes it less likely that the water collection box 9 will affect the volume of the cooking cavity 62, thereby further making full use of the space at the top of the cooking cavity 62 and improving the space utilization rate of the cooking cavity 62.

[0331] In any of the above embodiments, as exemplarily shown in Figures 12, 16, 17, and 18, the steam cooking appliance further includes: two second supports 600, respectively disposed on two inner sidewalls of the housing 6 that are opposite each other along the width direction, for supporting the food carrier 400; wherein, a first support 500 is installed on the top of one of the second supports 600, and the second support 600 is provided with a plurality of support parts 610, which are spaced apart along the height direction of the housing 6, and the two second supports 600 can install the food carrier 400 at multiple positions along the height direction through the plurality of support parts 610.

[0332] In this embodiment, the second bracket 600 can be used to support and install the food carrier 400, such as the baking tray 410, and adjust the installation height of the food carrier 400. The first bracket 500 is installed on top of the second bracket 600. In this structure, the water receiving box 9 and the first bracket 500 are directly installed on the support bracket of the food carrier 400, such as the baking tray 410. This allows the installation of the water receiving box 9 to be achieved using the existing brackets within the housing 6, thereby simplifying the overall product structure and reducing the overall product cost.

[0333] The first support 500 and the second support 600 are integral structures. For example, the first support 500 and the second support 600 can be integrally processed and formed. In this case, the first support 500 and the second support 600 are combined into one support. Alternatively, the first support 500 and the second support 600 are separate structures that can be detached or integrally connected.

[0334] Alternatively, the first bracket 500 can be installed on only one of the second brackets 600. In this case, the first bracket 500 and the second bracket 600 can be set separately, and then the first bracket 500 and the second bracket 600 can be detachably connected or connected as a whole. In other solutions, the first bracket 500 can be installed on both second brackets 600. In this case, the brackets on both sides of the cooking cavity 62 are consistent.

[0335] The structure and shape of the first support 500 and the second support 600 can be the same or slightly different.

[0336] In any of the above embodiments, as exemplarily shown in Figures 15 and 16, a first flange 92 is provided around the water receiving box 9 in the circumferential direction, and the first flange 92 extends from the inner side of the water receiving box 9 to the outer side; the first bracket 500 includes a support bar 510, and the water receiving box 9 is mounted on the support bar 510 through the first flange 92.

[0337] In this embodiment, the first flange 92 enables the positioning and installation of the water receiving box 9. To ensure the installation of the first bracket 500 with the water receiving box 9, a support strip 510 is provided on the first bracket 500. The support strip 510 can be supported at the bottom of the first flange 92 to support the water receiving box 9. To ensure the installation stability of the water receiving box 9, the shape of the support strip 510 can be adapted to the outer wall of the water receiving box 9, and the length of the support strip 510 can be set with reference to the outer periphery of the water receiving box 9.

[0338] For example, when the water receiving box 9 is elongated, the support strip 510 can cover three sides of the water receiving box 9 to ensure the stability of the support strip 510 in supporting the water receiving box 9. When the water receiving box 9 is circular or near-circular, the support strip 510 can cover more than three-quarters of the circumference of the water receiving box 9.

[0339] In any of the above embodiments, as exemplarily shown in Figures 15, 16, and 18, the water receiving box 9 has an elongated structure and is arranged along the front-rear direction of the housing 6. The elongated structure of the water receiving box 9 reduces the width it occupies, thereby improving the space utilization of the cooking cavity 62.

[0340] For example, the water receiving box 9 has a long strip structure, and the support strip 510 supports three sides of the water receiving box 9. This ensures the installation stability of the water receiving box 9.

[0341] As exemplarily shown in Figures 12 and 18, the heating device 800 includes a heating element 810 mounted on the top of the housing 6.

[0342] In this embodiment, the heating device 800 can be of various heating forms, such as infrared heating, thermal radiation heating, or electromagnetic heating. For example, a heating element 810 can be installed on the top of the cooking cavity 62 to heat the food. At this time, the water tank assembly 3 can be installed on the outer top of the housing 6, and the water receiving box 9 can be positioned close to the top of the cooking cavity 62, so that the heating element 810 can be used to heat the water in the water receiving box 9 into steam.

[0343] In any of the above embodiments, as exemplarily shown in Figures 11, 12 and 18, the steam cooking appliance further includes: a water tank assembly 3, installed outside the cooking cavity 62, for supplying water to the water receiving box 9; the water tank assembly 3 is located above the location of the water receiving box 9 along the height direction of the body 6.

[0344] In this embodiment, when it is necessary to add water to the ingredients, water can be added to the water tank assembly 3. The water in the water tank assembly 3 can flow into the water receiving box 9. In this way, during the cooking process, the water in the water receiving box 9 can be heated into steam to replenish the ingredients.

[0345] The water tank assembly 3 is detachably installed on the tank body 6. Disassembly of the water tank assembly 3 facilitates the addition of water and cleaning of the water tank assembly 3.

[0346] In any of the above embodiments, exemplarily, along the height direction of the tank 6, the water tank assembly 3 is located above the location of the water receiving box 9.

[0347] In this embodiment, the water tank assembly 3 is set relatively high, while the water receiving box 9 is set relatively low. This allows the water in the water tank assembly 3 to fall under the influence of gravity, making the water flow more smoothly. This reduces the reliance on water pumps and electrical controls, thereby simplifying the product structure and reducing product costs.

[0348] In any of the above embodiments, water in the water tank assembly 3 can flow into the water receiving box 9 under the action of gravity.

[0349] In this embodiment, there is no power equipment between the water tank assembly 3 and the water receiving box 9. The water in the water tank assembly 3 flows into the water receiving box 9 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components, which makes the entire water circuit structure very simple.

[0350] This structure allows for the elimination of water in the water tank assembly 3 when no additional water is needed for the food.

[0351] In any of the above embodiments, exemplarily as shown in Figures 12, 14, and 15, the water receiving box 9 includes a water receiving trough 94, and the steam cooking appliance further includes: a connector 700 disposed in the housing 6, with the outlet end of the connector 700 located above the water receiving trough 94 along the height direction of the housing 6; and a connecting pipe 8 for connecting the water tank assembly 3 and the connector 700, so as to transport water in the water tank assembly 3 to the water receiving trough 94 through the connecting pipe 8 and the connector 700. Exemplarily, the outlet end of the connector 700 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62.

[0352] In this embodiment, the water receiving box 9 is an open-topped water receiving trough 94. A connector 700 is installed on the housing 6, positioned above the water receiving trough 94, allowing water in the connector 700 to fall into the water receiving trough 94 under gravity. Simultaneously, steam generated by heating in the water receiving trough 94 can be directly discharged from the opening. This structure simplifies the design of the water receiving box 9, facilitating its processing and cleaning.

[0353] Meanwhile, to ensure water flow between the water tank assembly 3 and the water receiving box 9, a connector 700 is provided on the water receiving box 9 or the tank body 6, and a connecting pipe 8 is installed on the tank body 6. Water in the water tank assembly 3 can be transported to the water receiving box 9 through the connecting pipe 8 and the connector 700. This structure, by directly transporting water to the water receiving box 9 through the connecting pipe 8, guides the water and prevents it from flowing to other places. It also prevents water from falling directly from a height, thereby reducing water flow noise.

[0354] The outlet end of connector 700 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62. This guides the water flowing out of the outlet end of connector 700 away from the inner wall of the cooking cavity 62, preventing it from flowing along the inner wall. This allows the water flowing out of the outlet end of connector 700 to flow into the water collection box 9. This prevents water from flowing to other parts of the cooking cavity 62 and affecting the cooking of the product when water is supplied to the water collection box 9. This also ensures that there is no obvious turbulence at the outlet of connector 700, thus ensuring the cleanliness of other parts of the cooking cavity 62 and preventing them from getting wet.

[0355] In any of the above embodiments, exemplarily as shown in Figures 11, 13 and 14, the water tank assembly 3 includes a water outlet channel 34, and the steam cooking appliance further includes: a mounting housing 1, including a water storage tank 13 and a drain outlet 11 that are interconnected. The water storage tank 13 is provided corresponding to the water outlet channel 34 and is used to receive water from the water outlet channel 34; the drain outlet 11 is connected to the water receiving box 9, and the water in the water storage tank 13 can be discharged into the water receiving box 9 through the drain outlet 11.

[0356] In this embodiment, a water storage tank 13 is provided on the housing 1. After the water tank assembly 3 is installed, the water outlet channel 34 of the water tank assembly 3 is positioned corresponding to the water storage tank 13. Water discharged from the water outlet channel 34 can first enter the water storage tank 13 and then be discharged from the water storage tank 13 into the water receiving box 9. This design, with the water storage tank 13 provided for the water tank assembly 3, creates a large buffer area at the water outlet of the water tank assembly 3. When the water flow in the water tank assembly 3 is large or rapid, the water can be stored in the storage chamber to buffer the impact of the falling water, allowing the water to enter the cooking chamber 62 at a relatively stable flow rate. This avoids water splashing when the water flow is large and enters the water receiving box 9. Furthermore, the buffering effect of the water flow by the water storage tank 13 also prevents water from overflowing into other parts of the product, or even overflowing from the front end of the water tank assembly 3, when the water flow is obstructed.

[0357] For example, when water is added directly to the water tank assembly 3 without removing it, the water flow rate is very high. This water flow has a strong impact force, which can easily cause instability in the water flow output from the water tank assembly 3, leading to splashing. Furthermore, it can also cause water to overflow because it cannot drain quickly enough. This application effectively solves the problems of unstable water flow from the water tank assembly 3 causing splashing and overflow by additionally setting a water storage tank 13 at the water outlet channel 34.

[0358] Furthermore, this structure, due to the installation housing 1, allows the installation housing 1 to be connected to the water receiving box 9, etc., during use. The water tank assembly 3 does not need to be directly connected to the water receiving box 9, etc. This means that no pipe connection is required when installing and disassembling the water tank assembly 3, making it very convenient to disassemble and assemble the water tank assembly 3, and thus making it easier to remove the water tank assembly 3 for cleaning or adding water.

[0359] In any of the above embodiments, for example, as shown in FIG13, the inner bottom wall of the water storage tank 13 gradually decreases from a position away from the drain outlet 11 to a position close to the drain outlet 11.

[0360] In this embodiment, after water is added to the water tank assembly 3, the water in the water tank assembly 3 can enter the water storage tank 13 through the water outlet 34. The inner bottom wall of the water storage tank 13 gradually decreases from other positions to the drain outlet 11. In this way, when there is less water in the water storage tank 13, the water can gather at the water outlet of the water storage tank 13, making it easier to drain the water in the water storage tank 13. This can prevent water from remaining in the water storage tank 13 and reduce the amount of residual water in the water storage tank 13.

[0361] In any of the above embodiments, as exemplarily shown in Figures 11, 13, and 14, the mounting housing 1 includes a mounting cavity 12, one end of which is provided with a first mounting port 14. The water tank assembly 3 is detachably mounted on the mounting housing 1, and the water tank assembly 3 can move relative to the mounting housing 1 between a locked position and an unlocked position. In the locked position, the water tank assembly 3 is located inside the mounting cavity 12. In the unlocked position, a portion of the water tank assembly 3 is located outside the mounting cavity 12, and the other portion of the water tank assembly 3 is located inside the mounting cavity 12. When the water tank assembly 3 is in the locked position, along the height direction of the tank body 6, the outlet of the water outlet channel 34 is located above the water storage tank 13, so that the water in the water tank assembly 3 can flow into the water storage tank 13 under the action of gravity.

[0362] In these embodiments, the mounting housing 1 is used to support the mounting water tank assembly 3. During installation, the mounting housing 1 can be fixed to the housing 6 of a steam cooking appliance, and then the water tank assembly 3 can be detachably installed inside the mounting housing 1. This allows the water tank assembly 3 to be removed separately, making it convenient to remove the water tank assembly 3 from the product for cleaning and adding water.

[0363] Meanwhile, when the water tank assembly 3 is installed on the mounting housing 1, the water tank assembly 3 can move between an unlocked position and a locked position relative to the mounting housing 1. That is, the water tank assembly 3 has two states on the mounting housing 1. The first is the unlocked state, where the water tank assembly 3 can be removed from the mounting housing 1 for operations such as adding water and cleaning. The second is the locked state, where the water tank assembly 3 is locked and completely contained within the mounting cavity 12, making it impossible to remove from the mounting housing 1. This ensures the stability of the water tank assembly 3 on the mounting housing 1 during product operation.

[0364] When the water tank assembly 3 is in the unlocked position, at least a portion of the water tank assembly 3 is located outside the mounting cavity 12, which makes it easier for the user to remove the water tank assembly 3 and improves the ease of disassembly and assembly of the water tank assembly 3.

[0365] Meanwhile, when the water tank assembly 3 is in the locked position, the outlet of the water tank assembly 3 is directly located above the water storage tank 13, so that there is no obstruction at the outlet of the water tank assembly 3. This ensures that the water in the water tank assembly 3 can enter the water storage tank 13 as quickly as possible under the action of gravity.

[0366] Furthermore, with this structure, during installation, the water tank assembly 3 only needs to be placed inside the mounting housing 1, and during disassembly, the water tank assembly 3 can be directly removed. In other words, no additional pipe connection is required when installing and disassembling the water tank assembly 3, thus ensuring the ease of installation and disassembly of the water tank assembly 3.

[0367] In this design, along the height of the steam cooking appliance, the water outlet 34 is located above the water storage tank 13, which in turn is located above the water collection box 9. This arrangement causes the water outlet 34, drain outlet 11, and water collection box 9 to gradually decrease in height. This allows water to flow sequentially from the water outlet 34 into the water storage tank 13 under gravity, and then from the drain outlet 11 of the water storage tank 13 into the water collection box 9. Thus, the water in the water tank assembly 3 can flow into the water collection box 9 purely by gravity. With this structure, water in the water tank assembly 3 can flow into the water collection box 9 under gravity. That is, there is no power equipment between the water tank assembly 3 and the water receiving box 9. The water in the water tank assembly 3 flows into the water receiving box 9 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components. This reduces the dependence of the water tank assembly on water pumps and electronic control, thereby simplifying the product structure and reducing the product cost.

[0368] In any of the above embodiments, as exemplarily shown in Figures 11, 13 and 14, the mounting cavity 12 includes a first inner wall surface 122 and a second inner wall surface 124. The first inner wall surface 122 is adapted to the shape of the water tank assembly 3, and the second inner wall surface 124 is recessed towards the outside of the mounting cavity 12 to form a water storage tank 13.

[0369] In these embodiments, the water tank assembly 3 is installed inside the mounting housing 1, and the shape and size of a portion of the inner wall of the mounting cavity 12 are consistent with the housing of the water tank assembly 3. This allows the water tank assembly 3 to be installed precisely inside the mounting housing 1, ensuring the compatibility between the water tank assembly 3 and the mounting housing 1. This enables better positioning and installation of the water tank assembly 3 through the mounting housing 1.

[0370] Simultaneously, the lower inner wall of the rear part of the mounting cavity 12 can be recessed downwards to form the required water storage tank 13, thereby facilitating the buffering of the water output from the water tank assembly 3. In this structure, the mounting area of ​​the water tank assembly 3 and the water storage tank 13 are set together, so that the outlet of the water tank assembly 3 and the water storage tank 13 are directly connected. This ensures the fitting accuracy between the water tank assembly 3 and the water storage tank 13, making the water path smoother and preventing the water tank assembly 3 from being misaligned due to improper installation.

[0371] In any of the above embodiments, by way of example, the mounting housing 1 includes a bottom shell and a top cover, the bottom shell and the top cover forming a mounting cavity 12, and a portion of the bottom shell is bent away from the top cover to form a water storage tank 13.

[0372] In these embodiments, the mounting housing 1 is formed by a bottom shell and a top cover. A portion of the bottom shell is bent to form a water storage tank 13; that is, a portion of the bottom shell is sunken to form the water storage tank 13. This method of forming the water storage tank 13 is relatively simple, making the mounting housing 1 easier to manufacture, thereby reducing the manufacturing cost of the mounting housing 1.

[0373] Of course, in other solutions, ribs can be formed inside the mounting housing 1 to form a water storage tank 13, or the mounting housing 1 can be made thicker overall, and then a portion of the wall thickness can be removed to form the water storage tank 13.

[0374] In any of the above embodiments, as exemplarily shown in Figures 19, 20, 21, and 22, the steam cooking appliance further includes: a first limiting member 2, installed on the mounting housing 1; a second limiting member 32, disposed on the water tank assembly 3; when the water tank assembly 3 is in the locked position within the mounting cavity 12, the first limiting member 2 and the second limiting member 32 mutually limit each other to lock the water tank assembly 3; when the water tank assembly 3 is in the locked position within the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 can release the limitation between the first limiting member 2 and the second limiting member 32 to unlock the water tank assembly 3; and an elastic member 4, installed between the water tank assembly 3 and the mounting housing 1, for moving the water tank assembly 3 to the unlocked position after the water tank assembly 3 is unlocked.

[0375] In these embodiments, the water tank assembly 3 and the mounting housing 1 can be locked and unlocked by the first limiting member 2 and the second limiting member 32. After the water tank assembly 3 is unlocked, it can be removed from the mounting housing 1 for adding water, cleaning, or repair / replacement. When the water tank assembly 3 is locked, the fit between it and the mounting housing 1 is good, preventing the water tank assembly 3 from shaking and thus preventing it from slipping out of the mounting housing 1. Furthermore, with this structure, when installing the water tank assembly 3, it is only necessary to push it into the mounting housing 1. When it needs to be removed, pressing the water tank assembly 3 releases the constraint under the rebound of the elastic member 4, allowing the water tank assembly 3 to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or ejection device for disassembly of the water tank assembly 3, simplifying its structure and reducing its cost. In addition, in this structure, the water tank assembly 3 itself is provided with a second limiting member 32, so that the elastic member 4 can directly act on the water tank assembly 3 itself, thereby limiting the water tank assembly 3 directly through the first limiting member 2, making the limiting of the water tank assembly 3 more reliable, and also making the water tank assembly 3 more securely installed in the mounting shell 1, so that the water tank assembly 3 is not easy to loosen.

[0376] Furthermore, this design integrates the structure that drives the water tank assembly 3 to rebound directly into the water tank assembly 3 and the mounting housing 1, simplifying the overall structure of the water tank assembly 3 and thus reducing product costs. In addition, this structure uses the water tank assembly 3 itself as the rebound component, making the pressing and ejection of the water tank assembly 3 more reliable.

[0377] In these embodiments, as shown in Figures 19 and 21, the second limiting member 32 is used to define the position of the water tank assembly 3 within the mounting housing 1. Exemplarily, the second limiting member 32 and the water tank housing 30 are an integral structure.

[0378] In these embodiments, the second limiting member 32 can be a protruding structure or a recessed structure on the water tank outer shell 30. The second limiting member 32 and the water tank outer shell 30 are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member 32 and the water tank outer shell 30 can be separately provided, and then the second limiting member 32 can be detachably installed on the water tank outer shell 30.

[0379] In any of the above embodiments, exemplarily, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. After the water tank assembly 3 is unlocked, the elastic member 4 can extend to push a part of the water tank assembly 3 out of the mounting housing 1 and move the valve assembly 36 from the second position to the first position to close the water outlet channel 34.

[0380] In these embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can extend to push the water tank assembly 3 out of the mounting housing 1. At the same time, after the water tank assembly 3 extends out of the mounting housing 1, the push rod 16 separates from the water outlet channel 34, and the valve assembly 36 returns to the second position under the action of the elastic member 4, thereby closing the water outlet channel 34.

[0381] Of course, in other solutions, when the water tank assembly 3 is in the locked state, the elastic element 4 can also be set to the extended state.

[0382] In any of the above embodiments, as exemplarily shown in Figures 13 and 19, the water tank assembly 3 further includes: a valve assembly 36, installed at the water outlet channel 34 of the water tank assembly 3, capable of operating between a first position and a second position; a push rod 16 is provided on the mounting housing 1. When the water tank assembly 3 is in the locked position, the push rod 16 is inserted into the water outlet channel 34 and the valve assembly 36 is in the first position to open the water outlet channel 34. When the water tank assembly 3 is in the unlocked position or after the water tank assembly 3 is separated from the mounting housing 1, the valve assembly 36 moves from the first position to the second position under the action of the elastic member 4 to close the water outlet channel 34.

[0383] In this embodiment, after the water tank assembly 3 is correctly installed on the mounting housing 1, the valve assembly 36 can be lifted by the push rod 16, thereby opening the water outlet channel 34. After the water tank assembly 3 is unlocked or removed, the valve assembly 36 can automatically return to the second position under the action of the elastic element 4 to close the water outlet channel 34. This makes the opening and closing of the water tank assembly 3 very convenient. This structure can achieve the opening and closing of the water tank assembly 3 purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly 3 more durable. At the same time, in this structure, the elastic element 4 used for the telescopic installation of the water tank assembly 3 and the elastic element 4 required for the valve assembly 36 are the same part, that is, the pop-out structure of the water tank assembly 3 and the opening and closing structure of the water outlet of the water tank assembly 3 share a single elastic element 4, thereby simplifying the product structure.

[0384] As exemplarily shown in Figures 13 and 19, the valve assembly 36 includes: a valve stem 38 slidably mounted within the outlet channel 34; and a seal 39 mounted on the valve stem 38 and capable of moving with the valve stem 38 to open or seal the outlet channel 34.

[0385] For example, as shown in FIG13, the water outlet channel 34 includes a water outlet. When the valve assembly 36 is in the first position, the seal 39 blocks the water outlet. When the valve assembly 36 is in the second position, the seal 39 opens the water outlet.

[0386] In this embodiment, the seal 39 is disposed within the water outlet channel 34, near the water outlet. When the water tank assembly 3 is not installed on the product, the valve assembly 36 is in the first position, and the seal 39 blocks the water outlet, preventing water in the water tank assembly 3 from draining through the water outlet channel 34. After the water tank assembly 3 is installed, the valve assembly 36 is in the second position. At this time, the seal 39 is positioned away from the water outlet and opens the water outlet, connecting the water outlet and the water inlet. This allows water in the water tank assembly 3 to drain through the water outlet channel 34, facilitating water supply to the steam cooking appliance. With this structure, the seal 39, installed within the water outlet channel 34, can move along the outlet of the water outlet channel 34 when the valve assembly 36 closes the water outlet channel 34. This allows the seal 39 to squeeze out any remaining water in the water outlet channel 34, preventing excessive water residue. This also prevents leakage when the water tank assembly 3 is removed, thus avoiding any impact on the user experience.

[0387] Of course, in other solutions, as shown in Figure 19, the seal 39 can also be provided at the water inlet to open or block the water inlet.

[0388] In any of the above embodiments, exemplarily as shown in FIG13, at least a portion of the water outlet channel 34 is located within the water receiving cavity 300. The water outlet channel 34 includes a water inlet, and the water outlet channel 34 communicates with the water receiving cavity 300 through the water inlet. The water inlet is disposed on the side wall of the portion of the water outlet channel 34 located within the water receiving cavity 300. This arrangement allows the water inlet to be closer to the water outlet, thereby shortening the movement distance of the seal 39 and making it easier for the seal 39 to open the water outlet and connect the water outlet and the water inlet.

[0389] In any of the above embodiments, exemplarily as shown in Figures 11, 12, and 18, the steam cooking appliance includes a door 7. A food inlet / outlet 64 and a second mounting opening 66 are provided at a first end along a first direction of the housing 6. The door 7 is installed at the first end of the housing 6 to open or close the food inlet / outlet 64. The water tank assembly 3 can be pulled and installed onto the housing 6 via the second mounting opening 66 along the first direction. Exemplarily as shown in Figures 13 and 19, the water tank assembly 3 includes: a water tank shell 30, which includes a water-containing cavity 300 and a second inlet / outlet 307 communicating with the water-containing cavity 300. The second inlet / outlet 307 is located at one end of the water tank shell 30 along the first direction; a cover 302, detachably installed on the water tank shell 30 to open or close the second inlet / outlet 307; and a sealing ring 309, disposed between the water tank shell 30 and the cover 302 to seal the gap between them.

[0390] In this embodiment, the second mounting port 66 and the food inlet / outlet 64 are located on the same side, that is, the water tank assembly 3 is installed on the side of the housing 6 where the door 7 is located, for example, the water tank assembly 3 is located on the front side of the housing 6. Simultaneously, the water tank assembly 3 can also be installed onto the housing 6 along the front side of the housing 6, and the water tank assembly 3 can be pulled out in the front-back direction to achieve the assembly and disassembly of the water tank assembly 3. Furthermore, the water tank assembly 3 is also placed front-back on the housing 6, that is, the water tank assembly 3 is installed horizontally on the housing 6, not vertically. This reduces the space occupied by the height of the water tank assembly 3, preventing the entire product from being too tall, thus allowing the water tank assembly 3 to be installed on the top of the cooking cavity 62, thereby providing conditions for the water tank assembly 3 to use gravity for water release.

[0391] The water tank assembly 3 specifically includes a water tank shell 30 and a cover 302. The water tank shell 30 is provided with a second inlet / outlet 307, and the cover 302 is detachably mounted on the second inlet / outlet 307 of the water tank shell 30. To ensure a seal between the water tank shell 30 and the cover 302, a sealing ring 309 is provided between them. This sealing ring 309 ensures a sealed connection between the two, thereby preventing water leakage from the water tank assembly 3.

[0392] In the aforementioned oven designs, the water tank assembly 3 has a water inlet directly mounted on the side wall of the water tank outer shell 30 without a removable cover. This makes it impossible to open the interior of the water tank, hindering cleaning. In this application, a removable cover 302 is specifically designed. This allows for easy cleaning of the water tank assembly 3 by opening the cover 302, improving the convenience of cleaning and ensuring its cleanliness. Furthermore, this design allows users to easily inspect the interior of the water tank assembly 3 for dirt and grime, enabling them to detect dirt more quickly and clean it promptly. This provides users with greater peace of mind when using the water tank assembly 3.

[0393] Specifically, the first direction can be the front-to-back direction of the tank body 6. In this case, the water tank assembly 3 can be disassembled and assembled from the front side of the tank body 6. The cover 302 and the outer shell 30 of the water tank assembly 3 are also assembled along the front-to-back direction. This means that the water tank assembly 3 is installed horizontally on the tank body 6, rather than vertically. This reduces the space occupied by the height of the water tank assembly 3, preventing the entire product from becoming too tall.

[0394] In any of the above embodiments, as exemplarily shown in Figures 11 and 12, the housing 6 includes an inner liner 60, which forms a cooking cavity 62, and a water tank assembly 3 is installed above the inner liner 60.

[0395] In this embodiment, the water tank assembly 3 is installed relatively high to facilitate water discharge using gravity. Furthermore, this design allows for efficient use of the product's height, thereby reducing its width and footprint, and making it easier to store.

[0396] In any of the above embodiments, for example, as shown in FIG12, the housing 6 includes a first part and a second part, the door 7 is installed on the first part, the second part is located above the first part along the height direction of the housing 6, and the water tank assembly 3 is installed on the second part.

[0397] In this embodiment, the door 7 and the water tank assembly 3 are installed in different areas of the housing 6, so that the water tank assembly 3 can be exposed outside the door 7, so that the door 7 can be added without opening it, thus making it convenient to add water during the cooking process.

[0398] Among them, the sealing element 39 is a sealing ring 309, and one or more sealing ribs are provided on the outer side wall of the sealing ring 309, and one or more sealing ribs are in sealing contact with the inner side wall of the water outlet channel 34.

[0399] The heating device 800 is located on the top of the cooking cavity 62. It can heat the water tank 9 and also heat the food in the cooking cavity 62. In other words, this application uses the heat source on the existing product for heating, without the need to set up a separate heating structure for the water tank. This simplifies the product structure, reduces the cost of product upgrades, and makes it easier for the product to be promoted and updated.

[0400] To ensure the overall heating effect of the steam cooking appliance, additional heating devices 800 can be installed. For example, additional heating devices 800 can be installed at the bottom or sides of the cooking cavity 62 to ensure the overall heating effect of the product on the food.

[0401] In any of the above embodiments, exemplarily as shown in Figures 19, 21, and 22, the second limiting member 32 includes a guide slide 320, which includes a limiting groove. As shown in Figure 20, the first limiting member 2 includes a movable member 22, which is mounted on the mounting housing 1, and a portion of the movable member 22 is located within the guide slide 320. When the water tank assembly 3 is installed into the mounting cavity 12, at least a portion of the movable member 22 can move from the first end of the guide slide 320 to the limiting groove and be limited within the limiting groove. When the water tank assembly 3 is located within the mounting cavity 12, pressing the water tank assembly 3 into the mounting cavity 12 allows at least a portion of the movable member 22 to move towards the second end of the guide slide 320 until it separates from the limiting groove, thereby unlocking the water tank assembly 3.

[0402] In these embodiments, the first limiting member 2 includes a movable member 22, which can be a rotating member or a sliding member. When the water tank assembly 3 is installed inside the mounting housing 1 or removed from the mounting housing 1, the movable member 22 can move relative to the guide slide 320. A limiting groove is provided in the guide slide 320, which restricts the movable member 22 to ensure that the water tank assembly 3 can be locked in the third position. Subsequently, when it is necessary to remove the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 to move inward. This allows the movable member 22 to move again to the position separated from the limiting groove, thus limiting the water tank assembly 3 and placing it in an unlocked state. After the water tank assembly 3 is unlocked, the elastic member 4 can rebound, pushing the water tank assembly 3 a distance outward from the mounting housing 1, thereby automatically ejecting the water tank. This facilitates subsequent disassembly of the water tank assembly 3 for cleaning, adding water, or maintenance.

[0403] In this configuration, when the water tank assembly 3 is pulled out of the mounting housing 1, the movable part 22 can continue to slide as before, instead of sliding back. This design ensures that the movement path of the movable part 22 is inconsistent when the water tank assembly 3 is inserted into the mounting housing 1 and when it is pulled out of the mounting housing 1, thereby making the locking and unlocking engagement between the movable part 22 and the guide slide 320 more reliable.

[0404] Conversely, when the water tank assembly 3 is unlocked, at least a portion of the movable part 22 can also move back toward the first end of the guide slide 320 until the movable part 22 separates from the limiting groove.

[0405] In any of the above embodiments, as exemplarily shown in FIG20, the movable member 22 includes a slider that can slide along the guide slide 320 and be confined in the limiting groove when the water tank assembly 3 is located in the mounting cavity 12.

[0406] In these embodiments, the movable component 22 includes a sliding component. The sliding component slides along the guide rail 320, allowing the water tank assembly 3 to be inserted and removed. Simultaneously, after the water tank assembly 3 is inserted and installed in place, i.e., when the water tank assembly 3 is installed into the mounting cavity 12, the sliding component can be better engaged in the limiting groove, thus preventing the sliding component from sliding and locking the water tank assembly 3. When it is necessary to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inward to retract the limiting groove, allowing the sliding component to slide out of the limiting groove along the second guide surface. This releases the limiting fit between the sliding component and the limiting groove, freeing the water tank assembly 3 and facilitating its removal for heating, adding water, cleaning, or repair / replacement.

[0407] As shown in Figure 11, a second mounting port 66 is provided at the first end of the housing 6 along the first direction. The second mounting port 66 is provided correspondingly to the first mounting port 14 and avoids the first mounting port 14. For example, the end of the mounting shell 1 with the first mounting port 14 can be placed in the second mounting port 66 so that the water tank assembly 3 can be inserted into the mounting shell 1 from the front side of the housing 6.

[0408] In any of the above embodiments, the steam cooking appliance, exemplarily, includes an oven and / or a steamer. Of course, the steam cooking appliance can also be other devices that require a water tank.

[0409] In Figure 22, the arrows indicate the movement trajectory of the movable part 22 within the guide slide 320.

[0410] The following example of a steam oven will be used to further illustrate the steam cooking appliance in this application.

[0411] In related solutions, steam ovens with humidification functions typically have an external water tank, along with an external steam generator, which actively generates steam by heating the water.

[0412] This embodiment proposes a steam oven with a built-in water tank and humidification function. In this oven, the water tank is built into the cavity, and passive heating is achieved using heat generated by a heating element within the cavity. The water tank is essentially a water basin, allowing for easy placement and retrieval by the user, facilitating water addition and maintenance. It is placed on top of a shelf without affecting the overall volume of the cavity.

[0413] In this structure, the water tank is combined with the internal shelves of the cavity to store water, and the heat from the heating element inside the cavity is used for passive heating to generate water vapor.

[0414] Meanwhile, this structure features a detachable water tank that is easy to assemble and disassemble, compact in size, and convenient for placement and water filling. It utilizes the existing heating source of existing models for passive heating to generate steam, effectively achieving the product's simple steaming function. Furthermore, the integrated opening design of the water tank facilitates cleaning and maintenance. Positioned on top of the shelf, close to the heating element at the top of the cavity, it enhances heat acquisition and achieves the automatic simple steaming effect. Additionally, the top of the shelf has mounting slots to support and accommodate the water tank, ensuring its load-bearing and secure function.

[0415] In one specific embodiment, the water tank can be placed on the left or right shelves, and the specific location is not limited;

[0416] In one specific embodiment, the shelf can be integrated with the sink, and the shelf can be disassembled for unified assembly and disassembly. Of course, the shelf and the sink can also be installed separately, and each can be assembled and disassembled independently.

[0417] In one specific embodiment, the water tank can be fixed to the heating element at the top of the cavity, eliminating the need for assembly with the shelf.

[0418] In one specific embodiment, a soft-plug valve can be installed at the bottom of the water tank, which can empty the residual water in the water tank without disassembly, eliminating the need for daily maintenance.

[0419] The enclosure includes an inner liner and a shell. The inner liner is installed inside the shell, and a space is provided between the outer wall of the inner liner and the inner wall of the shell to accommodate the outer shell and water tank assembly. The front of the shell has a front opening, through which the inner liner forms a cooking cavity. A second mounting port is also provided on the front of the shell for inserting the water tank assembly. The water tank assembly is inserted through this second mounting port between the inner liner and the shell.

[0420] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
