Description

Technical Field

[0001] 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

[0002] The oven with steam function in the relevant solution is equipped with a retractable water tank assembly. How to ensure the smooth extension and retraction of the water tank assembly is a problem that urgently needs to be solved. Utility Model Content

[0003] The present invention aims to at least solve the problem of how to ensure that the water tank assembly of a steam cooking appliance can expand and contract smoothly in the prior art or related technologies.

[0004] The first objective of this invention is to provide a water tank device.

[0005] The second objective of this invention is to provide a steam cooking appliance.

[0006] An embodiment of the first aspect of this utility model provides a water tank device for a steam cooking appliance. The water tank device includes: a mounting shell including a mounting cavity, one end of which is provided with a mounting port, and one of a guide rib and a guide groove is provided on the inner wall of the mounting cavity; a water tank assembly, which can be installed into the mounting cavity through the mounting port, and the other of a guide rib and a guide groove is provided on the outer wall of the water tank assembly; the guide groove includes an inlet section and a guide section connected to each other, the width of the inlet section is greater than the width of the guide section, and when the water tank assembly is inserted into the mounting cavity through the mounting port, the inlet section can guide the guide rib into the guide section.

[0007] The water tank device provided according to the embodiments of this utility model can be specifically used in steam cooking appliances, such as ovens. The water tank device specifically includes a mounting shell and a water tank assembly. The water tank assembly can be pressed into or popped out of the mounting shell. When the water tank assembly enters or exits the mounting shell, guide ribs can move along guide grooves, thereby guiding the water tank assembly's entry and exit. This allows the water tank assembly to smoothly enter and exit the mounting shell, ensuring the water tank assembly moves smoothly to the designated position, guaranteeing the accuracy of the water tank assembly's installation position and preventing damage to the water tank assembly due to incorrect installation by the user. Furthermore, it allows the water tank assembly to smoothly enter and exit the mounting shell without jamming or significant shaking during installation, thus improving the product's texture and quality, and ultimately enhancing the user experience.

[0008] The guide channel comprises an interconnected inlet section and a guide section. The inlet section is wider than the guide section, meaning the inlet of the guide channel is wider, effectively widening at the inlet. This structure reduces the difficulty of aligning the guide ribs and guide channel during the insertion and installation of the water tank assembly. This allows the guide ribs and guide channel to be roughly aligned during insertion into the housing, rather than requiring strict alignment. Even if the initial angle of the water tank assembly is slightly off, it can still enter the inlet section and be corrected to the correct angle under its guidance. This significantly reduces the difficulty of installing the water tank assembly, making installation more convenient.

[0009] In any of the above embodiments, optionally, the slot width of the inlet section gradually decreases from the end furthest from the guide section to the end closest to the guide section.

[0010] In this embodiment, the width of the inlet section gradually decreases from the outside to the inside, so that the inner sidewall of the inlet section can form an inclined guiding structure. After the guide rib is inserted into the inlet section of the guide groove, the inlet section can guide and correct the position of the guide rib, so that the guide rib can be aligned with the guide section. This allows the guide rib to smoothly transition from the inlet section to the guide section, thereby ensuring the smoothness of the water tank assembly during installation.

[0011] In any of the above embodiments, the inlet section may optionally be conical or horn-shaped.

[0012] In this embodiment, the inlet section can be designed in either a conical or flared shape when it is expanded outwards. Conical and flared shapes are relatively common and therefore easier to manufacture, thus reducing the manufacturing difficulty of the product.

[0013] In any of the above embodiments, optionally, the mounting housing includes a guide groove, and the mounting housing includes: a bottom shell; and a top cover, which is mounted on the bottom shell and forms a mounting cavity with the bottom shell; wherein the guide groove is disposed at the connection between the bottom shell and the top cover.

[0014] In this embodiment, the mounting housing consists of a bottom shell and a top cover, which facilitates the processing of the mounting housing and also makes it easy to open the mounting housing for installing other parts or cleaning the interior. A guide groove is provided on the mounting housing and is located at the connection between the bottom shell and the top cover, further facilitating the processing of the guide groove.

[0015] In any of the above embodiments, optionally, a portion of the guide groove is disposed on the bottom shell, and another portion of the guide groove is disposed on the top cover.

[0016] In this embodiment, part of the guide groove is machined on the bottom shell and part is machined on the top cover, so that after the bottom shell and the top cover are assembled, the guide groove can be formed at the connection between the two.

[0017] In any of the above embodiments, optionally, a guide protrusion is provided on the inner wall of the mounting housing, and a guide groove is provided on the guide protrusion.

[0018] In this embodiment, the guide protrusion allows a gap to be formed between the outer wall of the water tank assembly and the inner wall of the mounting cavity, thereby reducing the contact area between the water tank assembly and the mounting housing during installation. This reduces friction between the mounting housing and the water tank assembly, making the installation of the water tank assembly smoother.

[0019] In any of the above embodiments, optionally, a first protrusion is provided on the inner wall of the bottom shell, a second protrusion is provided on the inner wall of the top cover, and the guide groove is formed by the first protrusion and the second protrusion.

[0020] In this embodiment, the guide groove is formed by a first protrusion and a second protrusion. During processing, it is only necessary to process the first and second protrusions on the bottom shell and the top cover. This design makes the processing of the housing more convenient.

[0021] In any of the above embodiments, optionally, the water tank assembly includes a first end face and a second end face disposed opposite to each other. When the water tank assembly is inserted into the mounting cavity through the mounting port, the first end face enters the mounting cavity first. The guide ribs or guide grooves provided on the inner wall of the mounting cavity extend from the mounting port into the mounting cavity, and / or the guide ribs or guide grooves provided on the water tank assembly extend to the first end face.

[0022] In this embodiment, the guide groove or guide rib on the inner wall of the mounting cavity starts from the mounting opening, and the guide groove or guide rib on the water tank assembly extends all the way to the first end face. This makes the guide groove or guide rib more visible during water tank assembly installation, facilitating alignment and improving the ease of installation. Furthermore, this design allows the guide groove and guide rib to engage immediately upon contact between the water tank assembly and the mounting housing, resulting in a more stable installation of the water tank assembly.

[0023] Of course, in other designs, the guide groove and guide rib may not extend to the end.

[0024] The first end face of the water tank assembly can be the bottom face, and the second end face can be the top face.

[0025] In any of the above embodiments, optionally, a guide rib is provided on the water tank assembly, and an inclined guide surface is provided on one end of the guide rib near the first end face. The inclined guide surface extends outward along the radial direction of the water tank assembly from the first end face to the second end face.

[0026] In this embodiment, guide ribs are provided on the water tank assembly, and guide grooves are provided on the mounting housing. This reduces the wall thickness of the water tank assembly housing. By providing inclined guide surfaces on the guide ribs, the thickness of the guide ribs at the first end face is reduced, making it easier for the guide ribs to be guided into the guide grooves and avoiding interference between the guide ribs and other parts of the cooking cabinet.

[0027] In addition, setting an inclined guide surface can ensure a smooth transition between the guide ribs and the outer shell of the water tank, making the overall appearance of the water tank assembly smoother and thus improving the aesthetics of the water tank assembly.

[0028] Optionally, the inclined guide surface is a chamfered surface or a rounded corner surface.

[0029] In this embodiment, when processing the water tank assembly, the guide ribs can be chamfered or rounded to form a chamfered or rounded surface, thereby enabling the rapid and convenient processing of the required inclined flow guide surface.

[0030] In any of the above embodiments, optionally, the end of the guide rib away from the first end face is provided with a chamfer.

[0031] In this embodiment, by setting a chamfer at the other end of the guide rib, the interference between the guide rib and the mounting shell can be reduced, ensuring a smooth transition between the guide rib and the water tank shell, making the overall appearance of the water tank assembly smoother, thereby improving the aesthetics of the water tank assembly.

[0032] In any of the above embodiments, optionally, when the water tank assembly is installed in the mounting cavity, it can move between a first position and a second position relative to the mounting shell. When the water tank assembly is in the first position, the water tank assembly is located inside the mounting cavity, and when the water tank assembly is in the second position, a portion of the water tank assembly is located outside the mounting cavity.

[0033] In this embodiment, the water tank assembly can extend and retract relative to the mounting housing. When extended, the water tank assembly is in a second position; when retracted, it is in a first position. When water needs to be added, the water tank assembly can be locked in the first position to ensure water flow between the assembly and the steam cooking appliance. Conversely, when the water tank assembly needs to be removed, it can be moved to the second position for easy removal by the user for cleaning or adding water.

[0034] Optionally, in any of the above embodiments, it further includes: a second limiting member installed on the water tank assembly; a first limiting member installed on the mounting housing; and an elastic member installed 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 mutually limit 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 causes the first limiting member and the second limiting member to move relative to each other to unlock the water tank assembly. After the water tank assembly is unlocked, the elastic member can push the water tank assembly to the second position.

[0035] In this embodiment, the water tank assembly and the mounting housing can be locked and unlocked via a first limiting structure 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, preventing the water tank assembly from easily shaking and thus preventing it from slipping out of the mounting housing.

[0036] 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, combined with the first limiting structure, ensures reliable positioning and a more secure installation, preventing the water tank from shifting.

[0037] 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.

[0038] In any of the above embodiments, optionally, the water tank assembly includes a water tank shell, and a second limiting member is disposed on the water tank shell. The second limiting member and the water tank shell are an integral structure.

[0039] In this embodiment, the water tank assembly includes a water tank shell for holding water. A second limiting member is used to define the position of the water tank assembly within the shell. Further, the second limiting member can be a protrusion on the water tank shell or a recess on the water tank shell. The second limiting member and the water tank shell are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member and the water tank shell can be separately configured, and the second limiting member can be detachably installed on the water tank shell.

[0040] In any of the above embodiments, optionally, the second limiting member includes a guide slide, the guide slide including a limiting groove; the first limiting member includes a movable member, the movable member is mounted on the mounting housing, and a portion of the movable member is located within the guide slide; when the water tank assembly is installed in the first position within the mounting cavity, at least a portion of the movable member can move from the first end of the guide slide to the limiting groove and be limited within the limiting groove; when the water tank assembly is in the first position, pressing the water tank assembly into the mounting cavity allows at least a portion of the movable member to move towards the second end of the guide slide to separate from the limiting groove, thereby unlocking the water tank assembly.

[0041] In these embodiments, the first limiting member includes a movable member, which may specifically be a rotating member or a sliding member. When the water tank assembly is installed into or removed from the mounting housing, the movable member can move relative to the guide slide. A limiting groove is provided in the guide slide to restrict the movable member, ensuring that the water tank assembly can be locked in the first position. Subsequently, when it is necessary to remove the water tank assembly, it can be pressed into the mounting housing to move inward. This allows the movable member to move again to the position separating from the limiting groove, thus limiting the water tank assembly and placing it in an unlocked state. After the water tank assembly is unlocked, the elastic member rebounds, pushing the water tank assembly a distance outward from the mounting housing, thereby automatically ejecting the water tank for subsequent disassembly, cleaning, adding water, or maintenance.

[0042] Furthermore, when the water tank assembly is pulled out of the mounting housing, the moving part can continue to slide as before, instead of sliding back. This design ensures that the movement path of the moving part is inconsistent when the water tank assembly is inserted into and removed from the mounting housing, thereby making the locking and unlocking engagement between the moving part and the guide rail more reliable.

[0043] In any of the above embodiments, optionally, the movable element includes a slider that can slide along a guide rail and is confined to a limiting groove when the water tank assembly is located in the mounting cavity.

[0044] In these embodiments, the movable component includes a sliding component. The water tank assembly can be inserted and removed by sliding the sliding component along the guide rail. Simultaneously, after the water tank assembly is inserted and installed in the first position, the sliding component is better engaged in the limiting groove, thus preventing further sliding and locking the water tank assembly. When it is necessary to remove the water tank assembly again, the assembly 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 engagement between the sliding component and the limiting groove, freeing the water tank assembly and facilitating its removal for adding water, cleaning, or repair / replacement.

[0045] In any of the above embodiments, optionally, the guide slide includes: a first guide surface; a second guide surface, set at a first angle to the first guide surface, and a limiting groove formed by the first guide surface and the second guide surface; a first slide, the first guide surface being disposed at the second end of the first slide, the first slide being used to guide the sliding member from the first end of the first slide to the first guide surface during the process of the water tank assembly moving from the mounting port into the mounting cavity to the third position; when the water tank assembly is in the third position, the water tank assembly is released, and the water tank assembly moves to the outside of the mounting cavity to the first position under the action of the elastic member, and the sliding member moves along the first guide surface to the connection between the first guide surface and the second guide surface, and is limited to the connection between the first guide surface and the second guide surface; a second slide, one end of the second slide being connected to the end of the second guide surface away from the first guide surface, when the water tank assembly is in the first position, the water tank assembly is pressed into the mounting cavity, and the sliding member can move along the second guide surface into the second slide; during the process of the water tank assembly moving from the mounting port to the outside of the mounting cavity, the sliding member can move along the second slide.

[0046] In these embodiments, the first guide surface and the second guide surface can be connected to form a limiting groove. After the water tank assembly is installed in place, the sliding member is confined within the limiting groove by the rebound force of the elastic member. Thus, through the interaction between the limiting groove and the sliding member, the position of the water tank assembly can be limited, preventing the water tank assembly from falling out of the mounting cavity without other external forces. In order to guide the sliding member to enter the limiting groove formed by the first guide surface and the second guide surface normally, a first slide rail is provided. Through the first slide rail, the sliding member can be guided to move along a preset trajectory. This ensures that after the water tank assembly is installed in place, the sliding member can reach the bottom of the limiting groove exactly, preventing the sliding member from being jammed prematurely and causing the water tank assembly to fail to install correctly.

[0047] When it is necessary to disassemble the water tank assembly, the water tank assembly can be pressed into the mounting housing so that the other end of the sliding member can move along the second guide surface to separate from the limiting groove, thereby releasing the locking of the mounting housing to the water tank assembly, so that the water tank assembly can be pulled out from the mounting housing, thus realizing the disassembly of the water tank assembly relative to the mounting housing.

[0048] The guide slide also includes a second slide. When the water tank assembly is pulled out of the mounting housing, the sliding member can slide along the second slide, which can limit the position of the sliding member and guide the water tank assembly to prevent the water tank assembly from shifting and jamming with the mounting housing.

[0049] Furthermore, in this structure, the movement paths of the sliding components are inconsistent when the water tank assembly is inserted into the mounting housing and when the water tank assembly is pulled out of the mounting housing, forming a loop. This makes the locking and unlocking engagement between the sliding components and the guide rail more reliable.

[0050] Conversely, the second slide can be omitted, and the structure of the first slide and the first guide surface can be reasonably designed so that when the water tank assembly is unlocked, the other end of the sliding member can return to the first slide along the first guide surface.

[0051] In any of the above embodiments, optionally, the guide slide further includes: an expansion section disposed at the first end of the first slide, and a fourth guide surface disposed on the two inner sidewalls of the expansion section. The fourth guide surface is used to guide the sliding member to move into the first slide during the process of the water tank assembly moving from the mounting port into the mounting cavity.

[0052] In this embodiment, because the sliding member has a certain sliding range, its position is not fixed after the water tank assembly is removed. After the water tank assembly is correctly inserted into the mounting housing, the sliding member can always fall within the range of the outward expansion section. When the water tank assembly is inserted inward, the fourth guide surface guides the sliding member into the first slide rail. This structure ensures that the sliding member can slide into the first slide rail regardless of its initial position, and then move along a fixed trajectory to the limiting part. Therefore, before installing the water tank assembly, it is not necessary to reset the sliding member or specifically determine its position, making the installation of the water tank assembly more convenient.

[0053] Of course, in other solutions, the outer extension section and the fourth guide surface may not be set. In this case, in order to ensure that the slider can slide into the first slide, the position of the slider needs to be fixed in advance.

[0054] In any of the above embodiments, optionally, a limiting hole is provided on the mounting housing, and the slider is slidably mounted on the limiting hole, thereby limiting the sliding range of the slider.

[0055] In these embodiments, to prevent the slider from sliding excessively, a limiting hole is provided on the mounting housing. This limiting hole can limit the sliding range of the slider, so that the slider can only move within a predetermined area. This can limit the position of the slider and prevent the slider from moving to other positions and failing to cooperate with the second limiting member on the water tank assembly. This ensures that after the water tank assembly is installed on the water tank housing, the slider can always cooperate with the second limiting member to lock the water tank assembly.

[0056] In any of the above embodiments, optionally, the movable component includes: a rotating component, the first end of which is rotatably mounted outside the mounting housing, the mounting housing having a limiting hole, the second end of which passes through the limiting hole and is inserted into the mounting cavity, and a sliding component disposed on the second end of the rotating component, wherein the sliding component and the rotating component are an integral structure, or the sliding component and the rotating component are detachably connected.

[0057] In these embodiments, the movable component includes a rotating component, and a sliding component is disposed on the rotating component. The sliding component can be moved by the rotation of the rotating component. This structure allows for relatively convenient sliding installation of the sliding component.

[0058] In this design, the sliding component and the rotating component can form a single part, for example, they can be integrally molded or processed separately and then joined together to form a single structure. Alternatively, the sliding component and the rotating component can also be two completely independent parts.

[0059] In any of the above embodiments, the water tank device may optionally include: a press-fitting component disposed outside the mounting housing, wherein at least a portion of the rotating component is located between the press-fitting component and the mounting housing.

[0060] In this embodiment, the press-fitting component is used to press the rotating component toward the water tank assembly. This allows the press-fitting component to limit the position of the rotating component, so that the rotating component can abut against the water tank assembly, thus preventing the rotating component from separating from the water tank assembly during rotation.

[0061] Optionally, the press-fit component is elastic, and can press the rotating component against the water tank assembly through its elasticity. By setting the press-fit component as an elastic structure, the elastic force of the press-fit component can press the rotating component, so that the other end of the rotating component can always be in contact with the water tank assembly, avoiding the situation where the other end of the rotating component separates from the water tank assembly, which would prevent the water tank assembly from being unable to lock.

[0062] In any of the above embodiments, optionally, the water tank device further includes: a support structure disposed on the outer wall of the mounting housing and supported on the side of the rotating member near the mounting housing.

[0063] In this embodiment, to limit the height of the rotating component, a support structure is provided on the mounting housing to support the rotating component. This support structure allows for better control of the mounting height of the rotating component. Simultaneously, the support structure also reduces the contact area between the rotating component and the mounting housing, thereby reducing friction between them.

[0064] In any of the above embodiments, optionally, the water tank assembly includes: a water tank housing, the water tank housing including a water outlet channel; a valve assembly installed at the water outlet channel for opening or closing the water outlet channel; a push rod provided on the housing, the push rod being able to be inserted into the water outlet channel when the water tank assembly is installed in the first position, and push the valve assembly from the fourth position to the fifth position to open the water outlet channel; an elastic member located in the water outlet channel, one end of the elastic member being connected to the valve assembly, and the other end of the elastic member being connected to the inner wall of the water outlet channel, the elastic member also being used to push the water tank assembly from the fifth position back to the fourth position after the water tank assembly is unlocked, so as to close the water outlet channel.

[0065] A valve assembly is installed inside the water outlet channel, and a push rod is provided on the mounting housing. The water outlet channel can be opened and closed by the valve assembly, the push rod, and the elastic element. Specifically, when the water tank assembly is installed on the cooking appliance body and steam is required, the water tank assembly can be locked by the first and second limiting members. At this time, the push rod can be inserted into the water outlet channel, thereby pushing the valve assembly to move from the fourth position to the fifth position along the water outlet channel, thus opening the water outlet channel.

[0066] When the water tank assembly needs to be removed from the cooking appliance for water addition, press the water tank assembly first to unlock it. After unlocking, the external force exerted on the valve assembly by the push rod disappears, and the valve assembly returns to the fourth position under the action of the elastic element. This closes the water outlet channel of the water tank assembly, preventing water from flowing out. Simultaneously, the water tank assembly is pushed out under the action of the elastic element.

[0067] In this structure, the elastic element can push the water tank assembly out and also close the water outlet channel of the valve assembly. In other words, in this structure, the elastic element used for the telescopic installation of the water tank assembly and the elastic element required for the valve assembly are the same part. That is, the push-out structure of the water tank assembly and the opening and closing structure of the water outlet of the water tank assembly share a single elastic element, thereby simplifying the product structure.

[0068] Of course, in other solutions, the elastic components for the telescopic installation of the water tank assembly and the elastic components required for the valve assembly can also be two separate parts.

[0069] In any of the above embodiments, optionally, the valve assembly includes: a valve stem slidably mounted in the water outlet channel; and a seal mounted on the valve stem and capable of moving with the valve stem to open or seal the water outlet channel.

[0070] In this embodiment, the valve assembly specifically includes a valve stem and a seal. The valve stem is slidably mounted within the water outlet channel, and the seal is mounted on one end of the valve stem and can move with the valve stem, thereby opening or closing the water outlet channel by moving the seal.

[0071] The elastic element is typically a spring. It is installed between the valve stem and the water tank housing. Under normal conditions, the elastic element is compressed, and its rebound force compresses the sealing element, allowing it to close the water outlet channel. When the valve stem is pushed along the water outlet channel, it moves the sealing element and opens the water outlet channel, allowing water to flow out of the tank assembly. Simultaneously, the elastic element is compressed during this process. Therefore, after the external force on the valve stem disappears, the elastic element can return the valve stem to its initial position, causing the sealing element to close the water outlet channel again.

[0072] In any of the above embodiments, optionally, the water outlet channel includes an outlet and an inlet. When the valve stem is in the fourth position, the seal blocks the outlet. When the valve stem is in the fifth position, the seal opens the outlet, so that the inlet and outlet are connected.

[0073] In these embodiments, the seal is disposed within the water outlet channel and positioned near the water outlet. When the water tank assembly is not installed into the mounting housing, the valve stem is in the fourth position, and the seal blocks the water outlet, preventing water from leaking out of the water tank housing through the water outlet channel. When the water tank assembly is installed into the mounting housing, the push rod is inserted into the water outlet channel and pushes up the valve stem, placing it in the fifth position. At this point, the elastic element is compressed, and the seal and valve stem move together to the other side of the water inlet, connecting the water outlet and the water inlet. This allows water inside the water tank housing to be discharged through the water outlet channel, facilitating water supply to the steam cooking appliance. When it is necessary to remove the water tank assembly, the limiting mechanism between the water tank assembly and the housing assembly is released, the valve stem rebounds under the action of the elastic element, and the entire water tank assembly is ejected. With this structure, when the water tank assembly is ejected, the seal can move along the outlet of the water outlet channel. This allows the seal to squeeze out any remaining water in the water outlet channel, preventing excessive water residue. This also prevents the water tank assembly from leaking when it is removed, thus avoiding any impact on the user experience.

[0074] Furthermore, it is advisable to slightly tilt the water outlet channel downwards from the inlet to the outlet, which can also reduce the residual water in the outlet channel.

[0075] Optionally, the elastic element includes a spring capable of stretching or shortening.

[0076] In the above embodiments, optionally, the water tank device includes a water outlet channel; the mounting housing includes a water storage tank and a drain outlet that are interconnected, the water storage tank being provided corresponding to the water outlet channel for receiving water from the water outlet channel; the steam cooking appliance includes a water receiving tank that is connected to the drain outlet, and water in the water storage tank can be discharged from the drain outlet into the water receiving tank.

[0077] In this embodiment, when the water flow in the water tank assembly is large or rapid, the water can be stored in the water reservoir to buffer the impact of the falling water, allowing the water to enter the cooking cavity at a more stable flow rate. This avoids water splashing when the water flows into the receiving tank due to a large flow. Furthermore, the water reservoir's buffering effect prevents water from overflowing from the water tank assembly and spilling onto other parts of the product, or even overflowing from the front of the water tank assembly, if the water flow is obstructed.

[0078] In the above embodiments, optionally, the inner bottom wall of the water storage tank gradually moves away from the center of the mounting housing from a position away from the drain outlet to a position closer to the drain outlet. This allows water to accumulate at the outlet of the water storage tank when there is little water, making it easier to drain the water completely and preventing water residue from remaining in the tank, thus reducing residual water in the tank.

[0079] Optionally, along the height direction of the steam cooking appliance, the water outlet is located above the location of the water storage tank, and the water storage tank is located above the location of the water receiving tank.

[0080] A second aspect of this utility model provides a steam cooking appliance, including the water tank device provided in any one embodiment of the first aspect.

[0081] Since this type of steam cooking appliance has the water tank device provided in any embodiment of the first aspect, it has all the beneficial effects of the water tank device provided in any embodiment of the first aspect, which will not be repeated here.

[0082] In any of the above embodiments, optionally, the steam cooking appliance further includes: a housing, the housing including a cooking cavity and a food inlet / outlet, the food inlet / outlet communicating with the cooking cavity, a mounting shell installed on the housing, and a water tank assembly detachably installed on the housing; a door installed on the housing to open or close the food inlet / outlet; a heating device installed on the housing for heating the food in the cooking cavity; and a water tank installed inside the housing and communicating with the water tank assembly, wherein the water in the water tank can be heated into steam by the heating device.

[0083] In this embodiment, the steam cooking appliance includes a housing and a door. The housing contains a cooking chamber that communicates with a food inlet / outlet. The door is mounted on the housing and is used to open and close the food inlet / outlet. The water collection trough is specifically designed to store water, which can be heated into steam by a heating device to humidify the food inside the cooking chamber. With this design, the water collection trough can be heated directly using the product's existing heating device, eliminating the need for a separate heating structure and simplifying the product's structure. However, considering actual heating needs, a separate heating structure can be provided for the water collection trough.

[0084] In any of the above embodiments, optionally, the cabinet includes an inner liner that encloses a cooking cavity, and a water tank device is installed above the inner liner. This arrangement allows the water tank device to be installed 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.

[0085] Optionally, the cabinet includes a first part and a second part, with a door installed on the first part. Along the height direction of the cabinet, the second part is located above the first part, and the water tank assembly is installed on the second part. This allows the water tank assembly to be exposed through the door, so that water can be added without opening the door, making it convenient to add water during cooking.

[0086] In any of the above embodiments, optionally, the box body is provided with a first clearance opening to avoid the installation port, the installation port is located at a first end of the box body along a first direction, the first end of the box body along the first direction is provided with a food inlet and outlet, the door body is installed at the first end of the box body, and the water tank assembly can be installed onto the mounting shell along the first direction from the installation port; the water tank assembly includes: a water tank shell, the water tank shell includes a water-containing cavity and an inlet and outlet communicating with the water-containing cavity, the inlet and outlet are provided at one end of the water tank shell along the first direction; a cover body, which is detachably installed on the water tank shell to open or close the inlet and outlet; and a sealing ring, which is provided between the water tank shell and the cover body to seal the gap between the water tank shell and the cover body.

[0087] In this embodiment, a first clearance opening allows the water tank assembly to extend out of the tank body. The water tank assembly is installed on the side of the tank body where the door is located, for example, on the front side of the tank body. Simultaneously, the water tank assembly can also be installed onto the tank body along the front side, and it can be pulled out in a front-back direction for easy assembly and disassembly. Furthermore, the water tank assembly is placed front-back on the tank body, meaning it is installed horizontally rather than vertically, thus reducing the space occupied by the water tank assembly and preventing the overall product from becoming too tall.

[0088] Furthermore, the water tank assembly specifically includes a water tank shell and a cover. The water tank shell is provided with inlet and outlet ports, and the cover is detachably installed on the inlet and outlet ports of the water tank shell. At the same time, in order to ensure a seal between the water tank shell and the cover, a sealing ring is also provided between the two. This sealing ring can make the two seal together, thereby preventing water leakage from the water tank assembly.

[0089] In other oven designs, the water tank assembly typically features a water inlet directly on the side wall of the tank's outer shell without a removable cover. This makes it difficult to open the tank and clean its interior. In contrast, this application incorporates a removable cover, allowing for easy cleaning of the tank's interior. This significantly improves cleaning convenience and ensures the tank remains clean. Furthermore, the user can easily inspect the interior by opening the cover, allowing for quicker detection and cleaning of any dirt or debris. This provides users with greater peace of mind when using the water tank assembly.

[0090] The first direction can specifically refer to the front-to-back direction of the cooking unit. For example, the water tank assembly can be detached and installed from the front of the cooking unit. The water tank assembly's cover and outer shell are also assembled along the front-to-back direction, meaning the water tank assembly is installed horizontally on the cooking unit, rather than vertically. This reduces the space occupied by the water tank assembly, preventing the entire product from being too tall, allowing the water tank assembly to be installed on top of the inner tank, thus providing the condition for the water tank assembly to be lowered by gravity.

[0091] Optionally, steam cooking appliances include ovens and / or steamers. Of course, steam cooking appliances can also be other devices that require a water tank.

Detailed Implementation

[0110] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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.

[0111] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0112] The following reference Figures 1 to 14 The water tank device 100 and steam cooking appliance 200 provided in the embodiments of this application are described below.

[0113] like Figures 1 to 4As shown, an embodiment of the first aspect of this utility model provides a water tank device 100 for a steam cooking appliance. The water tank device 100 includes: a mounting shell 1, including a mounting cavity 12, one end of which is provided with a mounting port 14, and one of a guide rib 308 and a guide groove 15 is provided on the inner wall of the mounting cavity 12; a water tank assembly 3, which can be installed into the mounting cavity 12 through the mounting port 14, and the other of the guide rib 308 and the guide groove 15 is provided on the outer wall of the water tank assembly 3; the guide groove 15 includes an inlet section 152 and a guide section 154 connected to each other, the width of the inlet section 152 is greater than the width of the guide section 154, and when the water tank assembly 3 is inserted into the mounting cavity 12 through the mounting port 14, the inlet section 152 can guide the guide rib 308 into the guide section 154.

[0114] The water tank device 100 provided according to the embodiments of this utility model 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. When the water tank assembly 3 enters or exits the mounting housing 1, the guide rib 308 can move along the guide groove 15, thereby guiding the entry and exit of the water tank assembly 3. This allows the water tank assembly 3 to smoothly enter and exit the mounting housing 1, ensuring the water tank assembly 3 moves smoothly to the designated position, guaranteeing the accuracy of the installation position and preventing damage to the water tank assembly 3 due to incorrect installation by the user. Furthermore, it allows the water tank assembly 3 to smoothly enter and exit the mounting housing 1 without jamming or significant shaking during installation, thus improving the product's texture and quality, and enhancing the user experience.

[0115] Among them, such as Figure 3 and Figure 4 As shown, the guide groove 15 includes an inlet section 152 and a guide section 154 connected to each other. The width of the inlet section 152 is greater than the width of the guide section 154, meaning that the inlet of the guide groove 15 is wider, which is equivalent to the guide groove 15 having an outward expansion design at the inlet. With this structure, when inserting and installing the water tank assembly 3, the wider inlet section 152 reduces the difficulty of aligning the guide rib 308 and the guide groove 15. This allows the guide rib 308 and the guide groove 15 to be roughly aligned during the insertion and installation of the water tank assembly 3 into the mounting housing 1, without the need for strict alignment. In other words, even if the initial angle of the water tank assembly 3 is slightly off, it can still enter the inlet section 152 and be corrected to the correct angle under the guidance of the inlet section 152. This reduces the installation difficulty of the water tank assembly 3, making its installation more convenient.

[0116] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, the width of the slot in the inlet section 152 gradually decreases from the end furthest from the guide section 154 to the end closest to the guide section 154.

[0117] In this embodiment, the groove width of the inlet section 152 gradually decreases from the outside to the inside, thereby forming an inclined guide structure on the inner sidewall of the inlet section 152. After the guide rib 308 is inserted into the inlet section 152 of the guide groove 15, the inlet section 152 can guide and correct the position of the guide rib 308, so that the guide rib 308 can be aligned with the guide section 154. This allows the guide rib 308 to smoothly transition from the inlet section 152 to the guide section, thereby ensuring the smoothness of the water tank assembly 3 during installation.

[0118] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, the inlet section 152 is conical or trumpet-shaped.

[0119] In this embodiment, the inlet section 152 can be designed in either a conical or flared shape when it is expanded outwards. Conical and flared shapes are relatively common and therefore easier to manufacture, thus reducing the manufacturing difficulty of the product.

[0120] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, the mounting housing 1 includes a guide groove 15. The mounting housing 1 includes: a bottom shell 192; and a top cover 194, which is mounted on the bottom shell 192 and forms a mounting cavity 12 with the bottom shell 192. The guide groove 15 is provided at the connection between the bottom shell 192 and the top cover 194.

[0121] In this embodiment, the mounting housing 1 is composed of a bottom shell 192 and a top cover 194, which facilitates the processing of the mounting housing 1 and also facilitates opening the mounting housing 1 to install other parts or clean the interior of the mounting housing 1. A guide groove 15 is provided on the mounting housing 1, and the guide groove 15 is located at the connection between the bottom shell 192 and the top cover 194, which further facilitates the processing of the guide groove 15.

[0122] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, a portion of the guide groove 15 is disposed on the bottom shell 192, and another portion of the guide groove 15 is disposed on the top cover 194.

[0123] In this embodiment, part of the guide groove 15 is machined on the bottom shell 192 and part is machined on the top cover 194, so that after the bottom shell 192 and the top cover 194 are assembled, the guide groove 15 can be formed at the connection between the two.

[0124] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, a guide protrusion is provided on the inner wall of the mounting housing 1, and a guide groove 15 is provided on the guide protrusion. The guide protrusion includes a first protrusion 1922 and a second protrusion 1942.

[0125] In this embodiment, the guide protrusion allows a gap to be formed between the outer wall of the water tank assembly 3 and the inner wall of the mounting cavity 12, thereby reducing the contact area between the water tank assembly 3 and the mounting housing 1 during installation. This reduces the friction between the mounting housing 1 and the water tank assembly 3, making the installation of the water tank assembly 3 smoother.

[0126] In any of the above embodiments, optionally, as Figure 3 and Figure 4 As shown, a first protrusion 1922 is provided on the inner wall of the bottom shell 192, and a second protrusion 1942 is provided on the inner wall of the top cover 194. The guide groove 15 is formed by the first protrusion 1922 and the second protrusion 1942.

[0127] In this embodiment, the guide groove 15 is formed by the first protrusion 1922 and the second protrusion 1942. During processing, it is only necessary to process the first protrusion 1922 and the second protrusion 1942 separately on the bottom shell 192 and the top cover 194. This arrangement makes the processing of the mounting shell 1 more convenient.

[0128] In any of the above embodiments, optionally, as Figure 2 , Figure 3 and Figure 4 As shown, the water tank assembly 3 includes a first end face and a second end face that are arranged opposite to each other. When the water tank assembly 3 is inserted into the mounting cavity 12 through the mounting port 14, the first end face enters the mounting cavity 12 first. The guide rib 308 or guide groove 15 provided on the inner wall of the mounting cavity 12 extends from the mounting port 14 into the mounting cavity 12, and / or the guide rib 308 or guide groove 15 provided on the water tank assembly 3 extends to the first end face.

[0129] In this embodiment, the guide groove 15 or guide rib 308 on the inner wall of the mounting cavity 12 starts from the mounting port 14, and the guide groove 15 or guide rib 308 on the water tank assembly 3 extends all the way to the first end face. This makes the guide groove 15 or guide rib 308 easier to see during installation of the water tank assembly 3, making alignment easier and improving the ease of installation. Furthermore, this design allows the guide groove 15 and guide rib 308 to engage immediately upon contact between the water tank assembly 3 and the mounting housing 1, resulting in a more stable installation of the water tank assembly 3.

[0130] Of course, in other designs, the guide groove 15 and guide rib 308 may not extend to the ends.

[0131] The first end face of the water tank assembly 3 can be the bottom face, and the second end face can be the top face.

[0132] In any of the above embodiments, optionally, as Figure 2 As shown, the water tank assembly 3 is provided with a guide rib 308, and an inclined guide surface 3082 is provided on one end of the guide rib 308 near the first end face. The inclined guide surface 3082 extends outward along the radial direction of the water tank assembly 3 from the first end face to the second end face.

[0133] In this embodiment, guide ribs 308 are disposed on the water tank assembly 3, and guide grooves 15 are disposed on the mounting housing 1. This reduces the wall thickness of the water tank assembly 3. By providing inclined guide surfaces 3082 on the guide ribs 308, the thickness of the guide ribs 308 at the first end face is reduced, making it easier for the guide ribs 308 to be guided into the guide grooves 15 and avoiding interference between the guide ribs 308 and other parts of the cooking cabinet 6.

[0134] In addition, the inclined guide surface 3082 can ensure a smooth transition between the guide rib 308 and the water tank shell 30, making the overall appearance of the water tank assembly 3 smoother and thus improving the aesthetics of the water tank assembly 3.

[0135] Optionally, the inclined guide surface 3082 is a chamfered surface or a rounded corner surface.

[0136] In this embodiment, when processing the water tank assembly 3, the guide rib 308 can be chamfered or rounded to form a chamfered or rounded surface, thereby enabling the required inclined guide surface to be processed quickly and conveniently.

[0137] In any of the above embodiments, optionally, as Figure 2 As shown, the end of the guide rib 308 away from the first end face has a chamfer.

[0138] In this embodiment, by setting a chamfer at the other end of the guide rib 308, the interference between the guide rib 308 and the mounting housing 1 can be reduced, ensuring a smooth transition between the guide rib 308 and the water tank housing 30, making the overall appearance of the water tank assembly 3 smoother, thereby improving the aesthetics of the water tank assembly 3.

[0139] In any of the above embodiments, optionally, when the water tank assembly 3 is installed in the mounting cavity 12, it can move between a first position and a second position relative to the mounting housing 1. When the water tank assembly 3 is in the first position, the water tank assembly 3 is located inside the mounting cavity 12. When the water tank assembly 3 is in the second position, a portion of the water tank assembly 3 is located outside the mounting cavity 12.

[0140] In this embodiment, the water tank assembly 3 can extend and retract relative to the mounting housing 1. When the water tank assembly 3 is extended relative to the mounting housing 1, it is in a second position; when it is retracted relative to the mounting housing 1, it is in a first position. When water needs to be added to the water tank assembly 3, it can be locked in the first position to ensure that the water tank assembly 3 is connected to the water passage on the steam cooking appliance 200. Conversely, when it is necessary to remove the water tank assembly 3, it can be moved to the second position to facilitate the user to remove the water tank assembly 3 for cleaning or adding water.

[0141] In any of the above embodiments, optionally, as Figure 2 , Figure 5 and Figure 6 As shown, the water tank device 100 further includes: a second limiting member 32, installed on the water tank assembly 3; a first limiting member 2, installed on the mounting housing 1; and 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 mutually limit each other 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 causes the first limiting member 2 and the second limiting member 32 to move relative to each other to unlock the water tank assembly 3. After the water tank assembly 3 is unlocked, the elastic member 4 can push the water tank assembly 3 to the second position.

[0142] In this embodiment, the water tank assembly 3 and the mounting housing 1 can be locked and unlocked via a first limiting structure 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 it and the mounting housing 1 is good, preventing the water tank assembly 3 from easily shaking and thus making it less likely to slip out of the mounting housing 1.

[0143] 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 structure. 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.

[0144] 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.

[0145] In any of the above embodiments, optionally, as Figure 2 , Figure 5 and Figure 6 As shown, the water tank assembly 3 includes a water tank shell 30, and a second limiting member 32 is disposed on the water tank shell 30. The second limiting member 32 and the water tank shell 30 are an integral structure.

[0146] In this embodiment, the water tank assembly 3 includes a water tank shell 30 for holding water. A second limiting member 32 is used to limit the position of the water tank assembly 3 within the mounting shell 1. Further, the second limiting member 32 can be a protrusion on the water tank shell 30 or a recess on the water tank shell 30. The second limiting member 32 and the water tank 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 shell 30 can be separately provided, and then the second limiting member 32 can be detachably installed on the water tank shell 30.

[0147] In any of the above embodiments, optionally, as Figure 5 , Figure 6 and Figure 7As shown, the second limiting member 32 includes a guide slide 320, which includes a limiting groove 327; 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 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 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 327, thereby unlocking the water tank assembly 3.

[0148] 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 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 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 that the water tank can be automatically popped out, making it convenient for the user to disassemble the water tank assembly 3 for cleaning, adding water or maintenance.

[0149] Furthermore, 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 arrangement 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.

[0150] in, Figure 6 The arrows in the diagram indicate the path of the sliding component 22 relative to the guide rail 320.

[0151] In any of the above embodiments, optionally, as Figure 1 , Figure 5 and Figure 6 As shown, the movable part 22 includes a sliding part 24, which can slide along the guide slide 320 and is limited to the limiting groove 327 when the water tank assembly 3 is located in the mounting cavity 12.

[0152] 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 adding water, cleaning, or repair / replacement.

[0153] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, 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 moving from the mounting port 14 into the mounting cavity 12 to the third position. When the water tank assembly 3 is in the third position, the water tank assembly 3 is released, and the water tank assembly 3 moves into the mounting cavity 12 under the action of the elastic member 4. When the water tank assembly 3 is in the first position, the sliding member 24 moves 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 the second slide 328 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 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 moving from the mounting port 14 to the outside of the mounting cavity 12, the sliding member 24 can move along the second slide 328.

[0154] 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.

[0155] 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.

[0156] like Figure 5 and Figure 6 As shown, 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 avoid the water tank assembly 3 from shifting and getting stuck with the mounting housing 1.

[0157] 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.

[0158] 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.

[0159] In any of the above embodiments, optionally, as Figure 5 and Figure 6As shown, the guide slide 320 further includes: an expansion section 329, which is disposed at the first end of the first slide 326. The two inner sidewalls of the expansion section 329 are provided with a fourth guide surface 3292. 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 moving from the mounting port 14 into the mounting cavity 12.

[0160] In this embodiment, 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.

[0161] 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.

[0162] In any of the above embodiments, optionally, as Figure 1 and Figure 7 As shown, the mounting housing 1 is provided with a limiting hole 10, and the sliding member 24 is slidably mounted on the limiting hole 10. The sliding range of the sliding member 24 can be limited by the limiting hole 10.

[0163] 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.

[0164] In any of the above embodiments, optionally, as Figure 1 and Figure 7As shown, the movable component 22 includes: a rotating component 26, the first end of which is rotatably mounted on the outside of the mounting housing 1, the mounting housing 1 having a limiting hole 10, the second end of which passes through the limiting hole 10 and is inserted into the mounting cavity 12, and a sliding component 24 disposed on the second end of the rotating component 26. The sliding component 24 and the rotating component 26 are an integral structure, or the sliding component 24 and the rotating component 26 are detachably connected.

[0165] In these embodiments, 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.

[0166] 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.

[0167] In any of the above embodiments, optionally, as Figure 1 and Figure 7 As shown, 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.

[0168] In this embodiment, the pressing 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 by the pressing member 5 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.

[0169] Optionally, the press-fitting component 5 is elastic, and the press-fitting component 5 can press the rotating component 26 towards the water tank assembly 3 through elasticity. By setting the press-fitting component 5 as an elastic structure, the elastic force of the press-fitting component 5 can press the rotating component 26, so that the other end of the rotating component 26 can always abut against the water tank assembly 3, avoiding the situation where the other end of the rotating component 26 separates from the water tank assembly 3, which would cause the water tank assembly 3 to fail to lock.

[0170] In any of the above embodiments, optionally, as Figure 1 and Figure 3 As shown, the water tank device 100 also includes a support structure 18, which is 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.

[0171] 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.

[0172] In any of the above embodiments, optionally, as Figure 7 and Figure 8 As shown, the water tank assembly 3 includes: a water tank housing 30, which includes 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 housing 1, which can be inserted into the water outlet channel 34 when the water tank assembly 3 is installed in the first position, and push the valve assembly 36 from the fourth position to the fifth position to open the water outlet channel 34; an elastic member 4 is located in the water outlet channel 34, one end of the elastic member 4 is connected to the valve assembly 36, and the other end of the elastic member 4 is connected to the inner wall of the water outlet channel 34. The elastic member 4 is also used to push the water tank assembly 3 from the fifth position back to the fourth position after the water tank assembly 3 is unlocked, so as to close the water outlet channel 34.

[0173] A valve assembly 36 is installed inside the water outlet channel 34, and a push rod 16 is provided on the mounting housing 1. The water outlet channel 34 can be opened and closed by the valve assembly 36, the push rod 16, and the elastic element 4. Specifically, when the water tank assembly 3 is installed on the cooking cabinet 6 and steam needs to be generated, the water tank assembly 3 can be locked by the first limiting element 2 and the second limiting element 32. At this time, the push rod 16 can be inserted into the water outlet channel 34, thereby pushing the valve assembly 36 to move from the fourth position to the fifth position along the water outlet channel 34, thus opening the water outlet channel 34.

[0174] When it is necessary to remove the water tank assembly 3 from the cooking unit 6 to add water, press the water tank assembly 3 first to unlock it. 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 fourth 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.

[0175] 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.

[0176] 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.

[0177] In any of the above embodiments, optionally, as Figure 7 and Figure 8 As shown, the valve assembly 36 includes: a valve stem 38, which is slidably mounted in the water outlet channel 34; and a seal 39, which is mounted on the valve stem 38 and can move with the valve stem 38 to open or seal the water outlet channel 34.

[0178] In this embodiment, the valve assembly 36 specifically includes a valve stem 38 and a seal 39. The valve stem 38 is slidably mounted in 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, so that the water outlet channel 34 can be opened or closed by moving the seal 39.

[0179] The elastic element 4 is typically a spring. It is installed between the valve stem 38 and the water tank housing 30. Under normal conditions, the elastic element 4 is compressed, and its rebound force compresses the sealing element 39, allowing it to close the water outlet channel 34. When the valve stem 38 is pushed along the water outlet channel 34, it moves the sealing element 39, opening the water outlet channel 34 and 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 stem 38 disappears, the elastic element 4 can move the valve stem 38 back to its initial position, causing the sealing element 39 to close the water outlet channel 34 again.

[0180] In any of the above embodiments, optionally, as Figure 7 , Figure 8 and Figure 9 As shown, 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.

[0181] 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.

[0182] Conversely, it can also be like Figure 11 As shown, the seal 39 is positioned at the water inlet 344. When the water tank assembly 3 is not installed in the mounting housing, the seal 39 seals the water 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 water outlet channel 34, thereby opening the inlet of the water outlet channel 34 and allowing water to drain from the water tank assembly 3. However, because the water outlet channel 34 has a certain length and is generally placed horizontally, some residual water will remain in the water outlet channel 34 after the water tank assembly 3 is unlocked. During the removal of the water tank assembly 3, this water will drip out, negatively impacting the user experience.

[0183] Furthermore, it is advisable to slightly tilt the water outlet channel 34 downwards from the inlet to the outlet, which can also reduce the residual water in the water outlet channel 34.

[0184] Optionally, the elastic element 4 includes a spring capable of extending or shortening.

[0185] In the above embodiments, optionally, as shown... Figure 7 and Figure 8As shown, the water tank device 100 includes a water outlet channel 34; the mounting housing 1 includes a water storage tank 122 and a drain outlet 17 that are interconnected. The water storage tank 122 is provided corresponding to the water outlet channel 34 and is used to receive water from the water outlet channel 34; the steam cooking appliance 200 includes a water receiving tank 9 that is connected to the drain outlet 17, and the water in the water storage tank 122 can be discharged from the drain outlet 17 into the water receiving tank 9.

[0186] In this embodiment, a water storage tank 122 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 set corresponding to the water storage tank 122. Water discharged from the water outlet channel 34 can first enter the water storage tank 122, and then be discharged from the water storage tank 122 into the water receiving tank 9 under the action of gravity. In this solution, the water storage tank 122 is provided for the water tank assembly 3, so that a large buffer area can be formed at the water outlet of the water tank assembly 3. When the water flow in the water tank assembly 3 is large or the water flow is rapid, the water can be stored in the water storage tank 122 first to buffer the impact of the water falling, so that the water flow can enter the cooking cavity 62 at a relatively stable flow rate. This can avoid the situation where water splashes after entering the water receiving tank 9 due to a large water flow. In addition, the water tank 122 buffers the water flow, which can prevent water from overflowing into other parts of the product or even overflowing from the front of the water tank assembly 3 when the water path is blocked.

[0187] In the above embodiments, optionally, as shown... Figure 7 and Figure 8 As shown, the inner bottom wall of the water storage tank 122 gradually moves away from the center of the mounting housing 1 from a position away from the drain outlet 17 to a position close to the drain outlet 17.

[0188] 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 122 through the water outlet 34. The inner bottom wall of the water storage tank 122 gradually decreases from other positions to the drain outlet 17. In this way, when there is less water in the water storage tank 122, the water can gather at the water outlet of the water storage tank 122, making it easier to drain the water in the water storage tank 122. This can prevent water from remaining in the water storage tank 122 and reduce the amount of residual water in the water storage tank 122.

[0189] Optionally, such as Figure 7 and Figure 8 As shown, along the height direction of the steam cooking appliance 200, the water outlet channel 34 is located above the location of the water storage tank 122, and the location of the water storage tank 122 is located above the location of the water receiving tank 9.

[0190] like Figures 1 to 14As shown, an embodiment of the second aspect of this utility model provides a steam cooking appliance 200, including the water tank device 100 provided in any embodiment of the first aspect.

[0191] Since the steam cooking appliance 200 has the water tank device 100 provided in any embodiment of the first aspect, the steam cooking appliance 200 has all the beneficial effects of the water tank device 100 provided in any embodiment of the first aspect, which will not be repeated here.

[0192] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the steam cooking appliance 200 also includes: a housing 6, which includes a cooking cavity 62 and a food inlet / outlet 64, the food inlet / outlet 64 being connected to the cooking cavity 62; a mounting shell 1 being mounted on the housing 6; and a water tank assembly 3 being detachably mounted on the housing 6; a door 7 being mounted on the housing 6 to open or close the food inlet / outlet 64; a heating device 68 being mounted on the housing 6 for heating the food inside the cooking cavity 62; and a water tank 9 being mounted inside the housing 6 and connected to the water tank assembly 3, the water in the water tank 9 being heated into steam by the heating device 68.

[0193] In this embodiment, the steam cooking appliance 200 includes a housing 6 and a door 7. The housing 6 contains a cooking chamber 62, which communicates with a food inlet / outlet 64. The door 7 is mounted on the housing 6 and is used to open and close the food inlet / outlet 64. A water tank 9 stores water, and the water in the water tank 9 can be heated into steam by a heating device 68 to humidify and replenish the food in the cooking chamber 62. With this configuration, the water tank 9 can be directly heated using the existing heating device 68, eliminating the need for a separate heating structure, thus simplifying the product's structure. Of course, considering actual heating needs, a separate heating structure can also be provided for the water tank 9.

[0194] The box body 6 and the door body 7 constitute the outer shell structure of the entire product, forming a cooking box body 6.

[0195] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the cabinet 6 includes an inner liner 66, which forms a cooking cavity 62, and a water tank device 100 is installed above the inner liner 66.

[0196] In this embodiment, the water tank device 100 is installed at a relatively high position to facilitate the drainage of the water tank assembly 3 using gravity. Furthermore, this arrangement allows for efficient use of the product's height, thereby reducing the product's width and floor space, and making it easier to store.

[0197] Optionally, such as Figure 12 and Figure 13 As shown, the box body 6 includes a first part and a second part. The door 7 is installed on the first part. Along the height direction of the box body 6, the second part is located above the first part, and the water tank device 100 is installed on the second part.

[0198] In this embodiment, the door 7 only covers the lower part of the box 6, and the top area of ​​the box 6 protrudes from the door 7. The water tank device 100 is installed on the top of the box 6, so that the water tank assembly 3 can be exposed outside 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.

[0199] In any of the above embodiments, optionally, as Figure 12 and Figure 13 As shown, the housing 6 is provided with a first clearance opening 60 that avoids the mounting opening 14. The mounting opening 14 is located at the first end of the housing 6 along the first direction. The first end of the housing 6 along the first direction is provided with a food inlet / outlet 64. The door 7 is installed at the first end of the housing 6. The water tank assembly 3 can be installed onto the housing 1 along the first direction through the mounting opening 14. The water tank assembly 3 includes: a water tank housing 30, which includes a water-containing cavity 302 and an inlet / outlet 342 communicating with the water-containing cavity 302. The inlet / outlet 342 is provided at one end of the water tank housing 30 along the first direction; a cover 31, which is detachably installed on the water tank housing 30 to open or close the inlet / outlet 342; and a sealing ring 33, which is provided between the water tank housing 30 and the cover 31 to seal the gap between the water tank housing 30 and the cover 31.

[0200] In this embodiment, a first clearance opening 60 is provided, allowing the water tank assembly 3 to extend out of the housing 6. The water tank assembly 3 is installed on the side of the housing 6 where the door 7 is located, for example, 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, and it can be pulled out in the front-back direction for easy assembly and disassembly. Furthermore, the water tank assembly 3 is placed front-back on the housing 6, meaning it is installed horizontally rather than vertically, thus reducing the space occupied by the water tank assembly 3 and preventing the overall product from becoming too tall.

[0201] Furthermore, such as Figure 2 and Figure 10 As shown, the water tank assembly 3 specifically includes a water tank shell 30 and a cover 31. The water tank shell 30 is provided with an inlet and outlet 342, and the cover 31 is detachably mounted on the inlet and outlet 342 of the water tank shell 30. Meanwhile, to ensure a seal between the water tank shell 30 and the cover 31, a sealing ring 33 is also provided between them. This sealing ring 33 ensures a sealed connection between the two, thereby preventing water leakage from the water tank assembly 3.

[0202] In other related solutions, the water tank assembly 3 on the oven has a water inlet directly installed on the side wall of the water tank outer shell 30 without a removable cover. This makes it impossible to open the inside of the water tank, making it very inconvenient to clean. In this application, however, a removable cover 31 is specifically designed. When cleaning the water tank assembly 3, the cover 31 can be opened to clean the inside of the water tank outer shell 30, thus improving the convenience of cleaning the water tank assembly 3 and ensuring its cleanliness. Furthermore, this design allows users to open the cover 31 and observe the internal condition of the water tank outer shell 30, facilitating timely inspection of any dirt or grime inside the water tank assembly 3. This allows users to more quickly identify and clean the water tank assembly 3, giving them greater peace of mind when using it.

[0203] Specifically, the first direction can be the front-to-back direction of the cooking cabinet 6. For example, the water tank assembly 3 can be disassembled and installed from the front of the cooking cabinet 6. The cover 31 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 6, rather than vertically. This reduces the height and space occupied by the water tank assembly 3, preventing the entire product from being too tall. This allows the water tank assembly 3 to be installed on top of the inner liner 66, thus providing the condition for the water tank assembly 3 to be lowered by gravity.

[0204] In any of the above embodiments, optionally, as Figure 14 As shown, the steam cooking appliance 200 also includes a pipe assembly for connecting the mounting housing 1 and the water receiving tank 9 to deliver water from the mounting housing 1 to the water receiving tank 9.

[0205] Furthermore, the water in the water tank device 100 can flow through the pipe assembly into the water receiving tank 9 under the action of gravity.

[0206] Optionally, the steam cooking appliance 200 includes an oven. Of course, the steam cooking appliance 200 can also be other devices that require a water tank, such as a steam oven.

[0207] In the above embodiments, optionally, as shown... Figure 2 and Figure 10As shown, the water tank outer shell 30 includes a first arc-shaped surface arranged along the circumferential direction of the water tank outer shell 30. The two ends of the first arc-shaped surface arranged along the circumferential direction of the water tank outer 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 water inlet / outlet 342 of the water tank outer shell 30.

[0208] 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 2 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.

[0209] 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.

[0210] Furthermore, 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 inlet / outlet 342 of the water tank shell 30. That is, the part of the first outer wall surface near the inlet / outlet 342 is arc-shaped, not flat. This makes the outer wall surface around the entire inlet / outlet 342 circular, which makes it convenient to set the cover 31 as circular as well. 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.

[0211] In any of the above embodiments, optionally, as Figure 13 and Figure 14 As shown, the steam cooking appliance 200 also includes: a connector 84, which is disposed in the housing 6, with the outlet end of the connector 84 corresponding to the water receiving tank 9; a connecting pipe 82, which is used to connect the drain outlet 17 and the connector 84, so that water in the water storage tank 122 can be transported to the water receiving tank 9 through the drain outlet 17, the connecting pipe 82 and the connector 84; wherein, the outlet end of the connector 84 is located inside the cooking cavity 62 and protrudes from the inner wall of the cooking cavity 62, and along the height direction of the housing 6, the outlet end of the connector 84 is located above the water receiving tank 9.

[0212] In this embodiment, the outlet end of the connector 84 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 the connector 84 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 the connector 84 to flow into the water receiving tank 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 receiving tank 9. This also ensures that there is no obvious turbulence at the outlet of the connector 84, thus ensuring the cleanliness of other parts of the cooking cavity 62 and preventing other parts of the cooking cavity 62 from getting wet.

[0213] Furthermore, to ensure that water in the water tank assembly 3 can flow to the connector 84, a connecting pipe 82 is installed between the connector 84 and the water tank assembly 3. Through the connecting pipe 82, water in the water tank assembly 3 can be promptly transported to the water receiving tank 9. This structure, with the connecting pipe 82, allows for more flexible installation of the water tank assembly 3, thus facilitating the overall layout of the product. Of course, in other solutions, the connecting pipe 82 can be omitted, and the outlet of the water tank assembly 3 can be directly connected to the connector 84.

[0214] In addition, by directly conveying water to the water receiving tank 9 through the connecting pipe 82, the water can be guided to prevent it from flowing into other places. At the same time, it can also prevent water from falling directly from a height, thereby reducing water flow noise.

[0215] The following section uses an oven as an example to further illustrate the water tank device and steam cooking appliance in this application.

[0216] Currently, steam ovens / steamers are generally equipped with water tanks for the machine to use. Conventional water tanks are rectangular, and the corresponding outer shell components are also rectangular, which can effectively fix and support the water tank. However, in this embodiment, the water tank is cylindrical, and the outer shell is also cylindrical, which cannot effectively fix the water tank. The structure of the outer shell components needs to be optimized to achieve smooth entry and exit of the water tank.

[0217] To address the aforementioned issues, in this embodiment, a limiting rib structure is provided on the outer shell assembly, and a guide rib is provided at the rear of the water tank. The combination of the limiting rib structure and the guide rib can restrict the water tank to the correct area inside the outer shell assembly, reducing the contact area between the two and lowering friction. The flared design of the opening of the outer shell assembly allows the user to push the water tank into the assembly more easily.
