Description

Technical Field

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

[0002] The oven with steam function in the relevant solution has a water collection box inside the cooking cavity, and water is added to the water collection box through a water tank. However, the placement of the water collection box inside the cooking cavity is unreasonable, resulting in low space utilization of the cooking cavity. Utility Model Content

[0003] The present invention aims to at least solve the problem that the water collection box of the steam oven is not placed in an unreasonable position in the prior art or related art, resulting in low space utilization of the cooking cavity.

[0004] Therefore, the first objective of this invention is to provide a steam cooking appliance.

[0005] To achieve the above objectives, an embodiment of the first aspect of this utility model provides a steam cooking appliance, comprising: a housing, the housing including a cooking cavity; a water receiving box installed inside the cooking cavity and disposed near the top of the cooking cavity; and a heating device installed inside the cooking cavity and located at the top of the cooking cavity for heating the water receiving box to heat the water in the water receiving box into steam.

[0006] The steam cooking appliance provided according to the embodiments of this utility model can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly, a heating device, and a water collection box. The housing assembly includes a housing body and a door, and the housing body has a cooking cavity for placing and heating food. The heating device is installed on the top of the cooking cavity and can heat the water collection box, which stores water. The water in the water collection box can be heated into steam by the heating device to humidify and replenish the food in the cooking cavity.

[0007] In this application, the water collection box is positioned at or near the top of the cooking cavity, thus placing it relatively high. When using a steam cooking appliance, food is typically placed in the lower middle part of the cooking cavity, leaving the top empty. This application, by placing the water collection box near the top of the cooking cavity, fully utilizes the space at the top, improving the space utilization rate of the cooking cavity, and ensuring that the placement of the water collection box does not affect the actual usable volume of the cooking cavity.

[0008] In any of the above embodiments, optionally, the water receiving box is detachably installed inside the cooking cavity. Removing the water receiving box facilitates its disassembly and cleaning.

[0009] In any of the above embodiments, optionally, the water collection box is located near the top edge of the cooking cavity. This arrangement makes the water collection box less likely to affect the volume utilization of the cooking cavity, thereby further making full use of the space at the top of the cooking cavity and improving the space utilization rate of the cooking cavity.

[0010] In any of the above embodiments, the steam cooking appliance may optionally include: a first bracket installed inside the cooking cavity, and a water collection box detachably installed on the first bracket.

[0011] In this embodiment, a first bracket is installed inside the cabinet, on the inner wall of the cabinet. For example, the first bracket can be installed on the cabinet using screws or clips. A water collection box is installed on the first bracket, which facilitates easier installation and removal of the water collection box. Furthermore, the first bracket's installation on the inner wall of the cabinet allows the water collection box to be installed at the top edge of the cooking cavity, making it less likely to affect the volume of the cooking cavity and thus further maximizing the use of the space at the top of the cooking cavity, improving its space utilization rate.

[0012] In any of the above embodiments, optionally, the steam cooking appliance further includes: two second supports, respectively disposed on two inner side walls of the housing that are opposite to each other along the width direction, for supporting the food carrier; wherein, the first support is installed on the top of one of the second supports, the second support is provided with multiple support parts, the multiple support parts are spaced apart along the height direction of the housing, and the second support can install the food carrier at multiple positions along the height direction through the multiple support parts.

[0013] In this embodiment, the second bracket can be used to support and install food carriers such as baking trays, and to adjust the installation height of the food carriers such as baking trays. The first bracket is installed on top of the second bracket; that is, in this structure, the water collection box and the first bracket are directly installed on the support bracket of the food carrier such as the baking tray. This allows the installation of the water collection box to be achieved using the existing brackets inside the box, thereby simplifying the overall product structure and reducing the overall product cost.

[0014] The first and second supports are integral structures, for example, the first and second supports can be integrally processed and formed, in which case the first and second supports are combined into one support, or the first and second supports are separate structures, which can be detached or integrally connected.

[0015] Alternatively, the first bracket can be installed on only one of the second brackets. In this case, the first and second brackets can be separate units, and then either detachably or integrally connected. In other solutions, the first bracket can be installed on both second brackets, in which case the brackets on both sides of the cooking cavity are aligned.

[0016] The structure and shape of the first and second supports can be the same or slightly different.

[0017] In any of the above embodiments, optionally, a flange is provided around the circumference of the water receiving box, and the flange extends from the inside to the outside of the water receiving box; the first bracket includes a support strip, and the water receiving box is installed on the support strip through the flange.

[0018] In this embodiment, the flange allows for the positioning and installation of the water receiving box. To ensure the installation of the first bracket with the water receiving box, a support strip is provided on the first bracket. The support strip rests on the bottom of the flange, thus supporting the water receiving box. To ensure the installation stability of the water receiving box, the shape of the support strip can be adapted to the outer wall of the water receiving box, and the length of the support strip can be set with reference to the outer perimeter of the water receiving box.

[0019] For example, when the water receiving box is long and narrow, the support strip can cover three sides of the water receiving box to ensure the stability of the support strip. When the water receiving box is circular or near-circular, the support strip can cover more than three-quarters of the circumference of the water receiving box.

[0020] In any of the above embodiments, optionally, the water receiving box has a long strip structure and is arranged along the front-to-back direction of the cabinet. The long strip structure of the water receiving box can reduce the width occupied by the water receiving box, thereby improving the space utilization of the cooking cavity.

[0021] Optionally, the water receiving box has a long, narrow structure, with support bars on three sides. This ensures the stability of the water receiving box during installation.

[0022] Optionally, the heating device includes a heating element mounted on the top of the enclosure.

[0023] In this embodiment, the heating device can be of various forms, such as infrared heating, thermal radiation heating, or electromagnetic heating. For example, a heating element can be installed on the top of the cooking cavity to heat the food. In this case, the water tank assembly can be installed on the outer top of the cabinet, and the water receiving box can be positioned close to the top of the cooking cavity, so that the heating element can heat the water in the water receiving box into steam.

[0024] In any of the above embodiments, optionally, the steam cooking appliance further includes: a water tank assembly installed outside the cooking cavity for supplying water to the water receiving box; the water tank assembly is located above the location of the water receiving box along the height direction of the appliance body.

[0025] In this embodiment, when it is necessary to add water to the ingredients, water can be added to the water tank assembly. The water in the water tank assembly can flow into the water receiving box. In this way, during the cooking process, the water in the water receiving box can be heated into steam to replenish the water to the ingredients.

[0026] The water tank assembly is detachably installed on the tank body. Disassembly of the water tank assembly facilitates water filling and cleaning.

[0027] In any of the above embodiments, optionally, the water tank assembly is located above the water receiving box along the height direction of the tank body.

[0028] In this embodiment, the water tank assembly is set relatively high, while the water receiving box is set relatively low. This allows the water in the water tank assembly to fall under the influence of gravity, making the drainage smoother. This reduces the reliance on water pumps and electrical controls, thereby simplifying the product structure and reducing product costs.

[0029] In any of the above embodiments, water in the water tank assembly can optionally flow into the water receiving box under the action of gravity.

[0030] In this embodiment, there is no power equipment between the water tank assembly and the water receiving box. The water in the water tank assembly flows into the water receiving box purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components, which makes the entire water circuit structure very simple.

[0031] This type of structure allows for the elimination of water tank components when it is not necessary to add water to the food.

[0032] In any of the above embodiments, optionally, the water receiving box includes a water receiving trough, and the steam cooking appliance further includes: a connector disposed in the housing, with the outlet end of the connector located above the water receiving trough along the height direction of the housing; and a connecting pipe for connecting the water tank assembly and the connector, so as to transport water in the water tank assembly to the water receiving trough through the connecting pipe and the connector. Further, the outlet end of the connector is located inside the cooking cavity and protrudes from the inner wall of the cooking cavity.

[0033] In this embodiment, the water receiving box is an open-topped water trough. A connector is installed on the box body, positioned above the water trough, allowing water in the connector to fall into the trough under gravity. Simultaneously, steam generated by heating in the water trough can be directly discharged from the trough opening. This structure simplifies the water receiving box, facilitating its manufacturing and cleaning.

[0034] Meanwhile, to ensure water flow between the water tank assembly and the receiving box, a connector is installed on the receiving box or the tank body, and a connecting pipe is installed on the tank body. Water in the water tank assembly can be transported to the receiving box through the connecting pipe and connector. This structure, by directly transporting water to the receiving box through the connecting pipe, guides the water and prevents it from flowing to other places. It also prevents water from falling directly from a height, thereby reducing water flow noise.

[0035] The outlet end of the connector is located inside the cooking cavity and protrudes from the inner wall of the cooking cavity. This guides the water flowing out of the outlet end, preventing it from flowing along the inner wall of the cooking cavity. As a result, the water flowing out of the outlet end can flow into the water collection box. This prevents water from flowing to other parts of the cooking cavity and affecting the cooking of the product when water is supplied to the water collection box. This also ensures that there is no obvious turbulence at the outlet end of the connector, thus ensuring the cleanliness of other parts of the cooking cavity and preventing them from getting wet.

[0036] In any of the above embodiments, the water tank assembly may optionally include a water outlet channel. The steam cooking appliance further includes: a mounting housing including a water storage tank and a drain outlet that are interconnected, the water storage tank being disposed corresponding to the water outlet channel for receiving water from the water outlet channel; the drain outlet being connected to a water receiving box, allowing water in the water storage tank to be discharged from the drain outlet into the water receiving box.

[0037] In this embodiment, a water storage tank is provided on the mounting housing. After the water tank assembly is installed, the water outlet channel of the water tank assembly corresponds to the water storage tank. Water discharged from the water outlet channel can first enter the water storage tank, and then be discharged from the water storage tank into the water receiving box. This design, with the water storage tank on the water tank assembly, creates a large buffer area at the water outlet. When the water flow in the water tank assembly is large or rapid, the water can be stored in the storage chamber to buffer the impact of the falling water, allowing the water to enter the cooking chamber at a relatively stable flow rate. This avoids water splashing when the water flow is large and enters the water receiving box. Furthermore, the buffering effect of the water storage tank prevents water from overflowing into other parts of the product, or even overflowing from the front of the water tank assembly, if the water flow is obstructed.

[0038] For example, when adding water directly to the water tank assembly without removing it, the water flow rate is very high. This water flow has a strong impact force, which can easily cause instability in the water flow output from the water tank assembly, leading to splashing. Furthermore, it can also cause water to overflow due to insufficient drainage. This application effectively solves the problems of unstable water flow leading to splashing and overflow by adding an additional water storage tank at the water outlet channel.

[0039] Furthermore, this structure, due to the installation housing, allows the housing to be connected to the water collection box, etc., during use. The water tank assembly does not need to be directly connected to the water collection box, etc. This eliminates the need for any pipe connections during the installation and removal of the water tank assembly, making it very convenient to disassemble and assemble the water tank assembly. This makes it easier to remove the water tank assembly for cleaning or adding water.

[0040] In any of the above embodiments, optionally, the inner bottom wall of the water storage tank gradually decreases from a position away from the drain outlet to a position close to the drain outlet.

[0041] In this embodiment, after water is added to the water tank assembly, the water in the water tank assembly can enter the water storage tank through the water outlet channel. The inner bottom wall of the water storage tank gradually decreases from other positions to the drain outlet. This allows water to accumulate at the outlet of the water storage tank when there is little water in it, making it easier to drain the water completely and preventing water residue in the water storage tank, thereby reducing the amount of residual water in the water storage tank.

[0042] In any of the above embodiments, optionally, the mounting housing includes a mounting cavity, one end of which is provided with a first mounting port. The water tank assembly is detachably mounted on the mounting housing, and the water tank assembly can move relative to the mounting housing between a locked position and an unlocked position. In the locked position, the water tank assembly is located inside the mounting cavity, and in the unlocked position, a portion of the water tank assembly is located outside the mounting cavity, while the other portion is located inside the mounting cavity. When the water tank assembly is in the locked position, along the height direction of the tank body, the outlet of the water outlet channel is located above the water storage tank, so that the water in the water tank assembly can flow into the water storage tank under the action of gravity.

[0043] In these embodiments, the mounting housing is used to support the water tank assembly. During installation, the mounting housing can be fixed to the body of the steam cooking appliance, and then the water tank assembly can be detachably installed inside the mounting housing. This allows the water tank assembly to be removed separately, making it convenient to remove the water tank assembly from the product for cleaning and water filling.

[0044] Simultaneously, when the water tank assembly is installed on the mounting housing, it can move relative to the housing between an unlocked position and a locked position, meaning the water tank assembly has two states on the mounting housing. The first is the unlocked state, where the water tank assembly can be removed from the mounting housing for operations such as adding water and cleaning. The second is the locked state, where the water tank assembly is locked and completely contained within the mounting cavity, preventing removal from the mounting housing. This ensures the stability of the water tank assembly on the mounting housing during product operation.

[0045] When the water tank assembly is in the unlocked position, at least a portion of the water tank assembly is outside the mounting cavity, which makes it easier for users to remove the water tank assembly and improves the ease of disassembly and assembly of the water tank assembly.

[0046] Meanwhile, when the water tank assembly is in the locked position, the outlet of the water tank assembly is directly above the water storage tank, so that there is no obstruction at the outlet of the water tank assembly. This ensures that the water in the water tank assembly can enter the water storage tank as quickly as possible under the action of gravity.

[0047] Furthermore, with this structure, during installation, the water tank assembly only needs to be placed inside the mounting housing, and during disassembly, the water tank assembly can be directly removed. In other words, no additional piping is required when installing or removing the water tank assembly, thus ensuring the ease of installation and removal of the water tank assembly.

[0048] In this design, along the height of the steam cooking appliance, the water outlet is located above the water storage tank, which in turn is located above the water collection box. This arrangement causes the water outlet, drain, and collection box to gradually decrease in height, allowing water to flow sequentially from the outlet into the water storage tank under gravity, and then from the drain into the collection box. This ensures that water in the tank flows into the collection box purely by gravity. In this structure, there is no power source between the tank and the collection box; water flows purely by gravity. This allows for water filling solely through mechanical means, eliminating the need for a water pump or any electronic controls. This reduces the tank's reliance on pumps and electrical systems, simplifying the product structure and lowering costs.

[0049] In any of the above embodiments, optionally, the mounting cavity includes a first inner wall surface and a second inner wall surface, the first inner wall surface being adapted to the shape of the water tank assembly, and the second inner wall surface being recessed in the direction of the outer side of the mounting cavity to form a water storage tank.

[0050] In these embodiments, the water tank assembly is installed inside the mounting housing, and the shape and size of a portion of the inner wall of the mounting cavity are consistent with the housing of the water tank assembly. This allows the water tank assembly to be installed precisely inside the mounting housing, ensuring the compatibility between the water tank assembly and the mounting housing. This enables better positioning and installation of the water tank assembly through the mounting housing.

[0051] Simultaneously, the lower inner wall of the rear part of the mounting cavity can be recessed downwards to form the required water storage tank, thereby facilitating the buffering of water output from the water tank assembly. In this structure, the installation area of ​​the water tank assembly and the water storage tank are located together, allowing direct communication between the outlet of the water tank assembly and the water storage tank. This ensures precise alignment between the water tank assembly and the water storage tank, resulting in smoother water flow and preventing misalignment between the water tank assembly and the water storage tank due to improper installation.

[0052] In any of the above embodiments, optionally, the mounting housing includes a bottom shell and a top cover, the bottom shell and the top cover forming a mounting cavity, and a portion of the bottom shell is bent away from the top cover to form a water storage tank.

[0053] In these embodiments, the mounting housing is formed by a bottom shell and a top cover. A portion of the bottom shell is bent to form a water reservoir; that is, a portion of the bottom shell is sunken to create the water reservoir. This method of forming the water reservoir is relatively simple, making the mounting housing easier to manufacture and thus reducing its manufacturing cost.

[0054] In any of the above embodiments, optionally, the steam cooking appliance further includes: a first limiting member installed on the mounting housing; a second limiting member disposed on the water tank assembly; when the water tank assembly is in the locked position within the mounting cavity, the first limiting member and the second limiting member mutually limit each other to lock the water tank assembly; when the water tank assembly is in the locked position within the mounting cavity, pressing the water tank assembly into the mounting cavity can release the limiting between the first limiting member and the second limiting member to unlock the water tank assembly; and an elastic member installed between the water tank assembly and the mounting housing, used to move the water tank assembly to the unlocked position after the water tank assembly is unlocked.

[0055] In these embodiments, 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. Furthermore, with this structure, installing the water tank assembly only requires pushing it into the mounting housing; removing it involves pressing it, and the elastic member releases the restriction, allowing the water tank assembly to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or ejector device for disassembly, simplifying the water tank assembly's structure and reducing its cost. In addition, this structure has a second limiting member on the water tank assembly itself, which allows the elastic member to act directly on the water tank assembly itself. This allows the water tank assembly to be directly limited by the first limiting structure, making the limiting of the water tank assembly more reliable and making the water tank assembly more securely installed in the housing, so that the water tank assembly is less likely to loosen.

[0056] Furthermore, this design integrates the mechanism that drives the water tank assembly to rebound directly into the water tank assembly and the mounting housing, simplifying the overall structure of the water tank assembly 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.

[0057] In these embodiments, the water tank assembly includes a water tank housing for holding water. A second limiting member is used to define the position of the water tank assembly within the housing.

[0058] In any of the above embodiments, optionally, the second limiting member and the water tank shell are an integral structure.

[0059] In these embodiments, the second limiting member can be a protruding structure or a recessed structure 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. Alternatively, 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.

[0060] In any of the above embodiments, optionally, when the water tank assembly is in the locked state, the elastic element is in the compressed state. After the water tank assembly is unlocked, the elastic element can extend to push a portion of the water tank assembly out of the mounting housing and move the valve assembly from the second position to the first position to close the water outlet channel.

[0061] In these embodiments, when the water tank assembly is in the locked state, the elastic element is in a compressed state. When the water tank assembly is in the unlocked state, the elastic element can extend to push the water tank assembly out of the mounting housing. Simultaneously, after the water tank assembly extends out of the mounting housing, the push rod separates from the water outlet channel, and the valve assembly returns to the second position under the action of the elastic element, thereby closing the water outlet channel.

[0062] In any of the above embodiments, optionally, the water tank assembly further includes: a valve assembly installed at the water outlet channel of the water tank assembly, capable of operating between a first position and a second position; a push rod is provided on the mounting housing, when the water tank assembly is in the locked position, the push rod is inserted into the water outlet channel and the valve assembly is in the first position to open the water outlet channel, and when the water tank assembly is in the unlocked position or the water tank assembly is separated from the mounting housing, the valve assembly moves from the first position to the second position under the action of the elastic element to close the water outlet channel.

[0063] In this embodiment, after the water tank assembly is correctly installed on the mounting housing, the valve assembly can be pushed up by the push rod, thereby opening the water outlet channel. After the water tank assembly is unlocked or removed, the valve assembly can automatically return to the second position under the action of the elastic element to close the water outlet channel. This makes opening and closing the water tank assembly very convenient. This structure can achieve the opening and closing of the water tank assembly purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly more durable. At the same time, 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 pop-up 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.

[0064] Optionally, the valve assembly includes: a valve stem slidably mounted within the outlet passage; and a seal mounted on the valve stem and capable of moving with the valve stem to open or seal the outlet passage.

[0065] Optionally, the water outlet channel includes a water outlet, and when the valve assembly is in the first position, the seal blocks the water outlet, and when the valve assembly is in the second position, the seal opens the water outlet.

[0066] In this embodiment, the seal is disposed within the water outlet channel, near the water outlet. When the water tank assembly is not installed on the product, the valve assembly is in the first position, and the seal blocks the water outlet, preventing water in the water tank assembly from draining through the water outlet channel. After the water tank assembly is installed, the valve assembly is in the second position. At this time, the seal is positioned away from the water outlet and opens the water outlet, connecting the water outlet and the water inlet. This allows water in the water tank assembly to drain through the water outlet channel, facilitating water supply to steam cooking appliances. With this structure, the seal, installed within the water outlet channel, can move along the outlet of the water outlet channel when the valve assembly closes it. This allows residual water in the water outlet channel to be squeezed out, preventing excessive water residue and thus avoiding leakage when the water tank assembly is removed, which would negatively impact the user experience.

[0067] In any of the above embodiments, optionally, at least a portion of the water outlet channel is located within the water-receiving cavity. The water outlet channel includes an inlet, and the water outlet channel communicates with the water-receiving cavity through the inlet. The inlet is disposed on the side wall of the portion of the water outlet channel located within the water-receiving cavity. This arrangement allows the inlet to be closer to the outlet, thereby shortening the movement distance of the seal and making it easier for the seal to open the outlet and connect the outlet and inlet.

[0068] In any of the above embodiments, optionally, the steam cooking appliance includes a door, a cooking inlet and a second mounting port are provided at a first end of the housing along a first direction, the door is installed at the first end of the housing to open or close the cooking inlet, and the water tank assembly can be pulled and installed onto the housing through the second mounting port along the first direction. Further, the water tank assembly includes: a water tank shell, the water tank shell including a water-containing cavity and a water inlet communicating with the water-containing cavity, the water inlet being provided at one end of the water tank shell along the first direction; a cover, detachably installed on the water tank shell to open or close the water inlet; and a sealing ring, provided between the water tank shell and the cover to seal the gap between the water tank shell and the cover.

[0069] In this embodiment, the second mounting port and the cooking inlet are located on the same side, meaning the water tank assembly is installed on the side of the housing with the door, such as the front side of the housing. The water tank assembly can also be installed onto the housing along the front side, and it can be pulled out in the front-to-back direction for easy assembly and disassembly. Furthermore, the water tank assembly is placed horizontally on the housing, not vertically. This reduces the space occupied by the water tank assembly, preventing the entire product from being too tall, allowing it to be installed at the top of the cooking cavity, thus providing the possibility for gravity-fed water flow.

[0070] The water tank assembly specifically includes a water tank shell and a cover. The water tank shell has a water inlet, and the cover is detachably installed over the water inlet of the water tank shell. Furthermore, to ensure a tight seal between the water tank shell and the cover, a sealing ring is installed between them. This sealing ring ensures a secure connection between the two, thereby preventing water leakage from the water tank assembly.

[0071] 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.

[0072] Specifically, the first direction can be the front-to-back direction of the tank body. In this case, the water tank assembly can be disassembled and installed from the front side of the tank body. The cover and outer shell of the water tank assembly are also assembled along the front-to-back direction, which means the water tank assembly is installed horizontally on the tank body, rather than vertically. This reduces the space occupied by the height of the water tank assembly, preventing the entire product from becoming too tall.

[0073] In any of the above embodiments, optionally, the cabinet includes an inner liner that forms a cooking cavity, and a water tank assembly is installed above the inner liner (i.e., on top of the inner liner).

[0074] In this embodiment, the water tank assembly is installed relatively high to facilitate water discharge using gravity. Furthermore, this design allows for efficient use of the product's height, reducing its width and footprint, thus making it easier to store.

[0075] Optionally, the tank also includes an outer shell with a front opening on its front side, and the inner liner is installed inside the outer shell. A second mounting port is provided on the front side of the outer shell, through which the water tank assembly can be inserted and installed between the top of the inner liner and the outer shell.

[0076] Optionally, the tank includes a first part and a second part, with a door installed on the first part. Along the height direction of the tank, the second part is located above the first part, and the water tank assembly is installed on the second part.

[0077] In this embodiment, the door and water tank assembly are installed in different areas of the tank, so that the water tank assembly can be exposed outside the door, so that water can be added without opening the door, thus making it convenient to add water during the cooking process.

[0078] The sealing element is a sealing ring, and one or more sealing ribs are provided on the outer wall of the sealing ring. The one or more sealing ribs are in sealing contact with the inner wall of the water outlet channel.

[0079] The heating device is located at the top of the cooking cavity and can heat the water tank as well as the food in the cooking cavity. In other words, this application uses the heat source on the existing product for heating, without the need to set up a separate heating structure for the water tank. This simplifies the product structure, reduces the cost of product upgrades, and makes it easier for the product to be promoted and updated.

[0080] In order to ensure the overall heating effect of the steam cooking appliance, other heating devices can also be installed. For example, additional heating devices can be installed at the bottom or sides of the cooking cavity to ensure the heating effect of the entire product on the food.

[0081] 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 into 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 in the limiting groove; when the water tank assembly is located in the mounting cavity, 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.

[0082] 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 third 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.

[0083] In this design, 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 arrangement results in different movement paths for the moving part when the water tank assembly is inserted into and removed from the mounting housing, thus making the locking and unlocking engagement between the moving part and the guide rail more reliable.

[0084] Conversely, when the water tank assembly is unlocked, at least a portion of the moving part can also move back toward the first end of the guide slide until the moving part separates from the limiting groove.

[0085] 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.

[0086] In these embodiments, the movable component includes a sliding component. The sliding component slides along the guide rail, allowing for the insertion and removal of the water tank assembly. Simultaneously, after the water tank assembly is inserted and installed in place, i.e., when the water tank assembly is installed into the mounting cavity, the sliding component can be better engaged in the limiting groove, thereby preventing the sliding component from sliding further and locking the water tank assembly. When it is necessary to remove the water tank assembly again, the water tank 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 heating, adding water, cleaning, or repair / replacement.

[0087] The tank body has a second mounting port at its first end along the first direction. The second mounting port is corresponding to the first mounting port and avoids the first mounting port. That is, the end of the mounting shell with the first mounting port is located at the second mounting port, so that the water tank assembly can be inserted into the mounting shell from the first mounting port on the front side of the tank body.

[0088] In any of the above embodiments, the steam cooking appliance may optionally include an oven and / or a steamer. Of course, the steam cooking appliance may also be other devices that require a water tank.

[0105] 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.

[0106] 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.

[0107] The following reference Figures 1 to 12 This application describes the steam cooking appliance provided in the embodiments of the present application.

[0108] like Figure 1 , Figure 2 and Figure 8 As shown, an embodiment of the first aspect of this utility model provides a steam cooking appliance, including: a housing 12, the housing 12 including a cooking cavity 16; a water collection box 3, installed inside the cooking cavity 16 and disposed near the top of the cooking cavity 16; and a heating device 2, installed inside the cooking cavity 16 and located at the top of the cooking cavity 16, for heating the water collection box 3 to heat the water in the water collection box 3 into steam.

[0109] The steam cooking appliance provided according to the embodiments of this utility model can specifically be a product such as an oven. The steam cooking appliance specifically includes a housing assembly 1, a heating device 2, and a water collection box 3. The housing assembly 1 includes a housing body 12 and a door 14. A cooking cavity 16 is provided inside the housing body 12, which is used to place and heat food ingredients. The heating device 2 is installed on the top of the cooking cavity 16 and can heat the water collection box 3. The water collection box 3 is used to store water, and the water in the water collection box 3 can be heated into steam by the heating device 2 to humidify and replenish the food ingredients in the cooking cavity 16.

[0110] In this design, the water collection box 3 is positioned at or near the top of the cooking cavity 16, thus placing it relatively high. When using a steam cooking appliance, food is typically placed in the lower middle part of the cooking cavity 16, leaving the top generally empty. This application's placement of the water collection box 3 near the top of the cooking cavity 16 fully utilizes the space at the top, improving the space utilization rate of the cooking cavity 16, and ensuring that the placement of the water collection box 3 does not affect the actual usable volume of the cooking cavity 16.

[0111] In any of the above embodiments, optionally, the water receiving box 3 is detachably installed inside the cooking cavity 16. Removing the water receiving box 3 facilitates its disassembly and cleaning.

[0112] In any of the above embodiments, optionally, as Figure 2 and Figure 8 As shown, the water collection box 3 is positioned near the top edge of the cooking cavity 16. This arrangement makes it less likely for the water collection box 3 to affect the volume utilization of the cooking cavity 16, thereby further maximizing the use of the space at the top of the cooking cavity 16 and improving the space utilization rate of the cooking cavity 16.

[0113] In any of the above embodiments, optionally, as Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the steam cooking appliance also includes: a first bracket 5, installed inside the cooking cavity 16, and a water collection box 3 detachably installed on the first bracket 5.

[0114] In this embodiment, a first bracket 5 is installed inside the housing 12. The first bracket 5 is mounted on the inner wall of the housing 12. For example, the first bracket 5 can be installed on the housing 12 by means of screws or clips. The water collection box 3 is mounted on the first bracket 5, which makes the installation and removal of the water collection box 3 more convenient. At the same time, the first bracket 5 is mounted on the inner wall of the housing 12, so that the water collection box 3 can be installed on the top edge of the cooking cavity 16. This makes it less likely that the water collection box 3 will affect the volume of the cooking cavity 16, thereby further making full use of the space at the top of the cooking cavity 16 and improving the space utilization rate of the cooking cavity 16.

[0115] In any of the above embodiments, optionally, as Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the steam cooking appliance also includes: two second supports 6, which are respectively disposed on two inner side walls of the housing 12 that are opposite each other in the width direction, for supporting the food carrier 10; wherein, the first support 5 is installed on the top of one of the second supports 6, and the second support 6 is provided with multiple support parts 62, which are spaced apart along the height direction of the housing 12, and the two second supports 6 can install the food carrier 10 at multiple positions along the height direction through the multiple support parts 62.

[0116] In this embodiment, the second bracket 6 can be used to support and install the food carrier 10, such as the baking pan 102, and adjust the installation height of the food carrier 10, such as the baking pan 102. The first bracket 5 is installed on top of the second bracket 6. In this structure, the water receiving box 3 and the first bracket 5 are directly installed on the support bracket of the food carrier 10, such as the baking pan 102. This allows the installation of the water receiving box 3 to be achieved using the existing brackets within the housing 12, thereby simplifying the overall product structure and reducing the overall product cost.

[0117] Among them, the first bracket 5 and the second bracket 6 are integral structures. For example, the first bracket 5 and the second bracket 6 can be integrally processed and formed. In this case, the first bracket 5 and the second bracket 6 are combined into one bracket. Alternatively, the first bracket 5 and the second bracket 6 are separate structures, which can be detached or integrally connected.

[0118] Alternatively, the first bracket 5 can be installed on only one of the second brackets 6. In this case, the first bracket 5 and the second bracket 6 can be set separately, and then the first bracket 5 and the second bracket 6 can be detachably connected or connected as a single unit. In other solutions, the first bracket 5 can be installed on both second brackets 6. In this case, the brackets on both sides of the cooking cavity 16 are consistent.

[0119] The structure and shape of the first support 5 and the second support 6 can be the same or slightly different.

[0120] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, a flange 32 is provided around the water receiving box 3, and the flange 32 extends from the inside to the outside of the water receiving box 3; the first bracket 5 includes a support bar 52, and the water receiving box 3 is installed on the support bar 52 through the flange 32.

[0121] In this embodiment, the flange 32 enables the positioning and installation of the water receiving box 3. To ensure the installation of the first bracket 5 with the water receiving box 3, a support bar 52 is provided on the first bracket 5. The support bar 52 can be supported at the bottom of the flange 32 to support the water receiving box 3. To ensure the installation stability of the water receiving box 3, the shape of the support bar 52 can be adapted to the outer wall of the water receiving box 3, and the length of the support bar 52 can be set with reference to the outer periphery of the water receiving box 3.

[0122] For example, when the water receiving box 3 is elongated, the support strip 52 can cover three sides of the water receiving box 3 to ensure the stability of the support strip 52 in supporting the water receiving box 3. When the water receiving box 3 is circular or near-circular, the support strip 52 can cover more than three-quarters of the circumference of the water receiving box 3.

[0123] In any of the above embodiments, optionally, as Figure 5 , Figure 6 and Figure 8 As shown, the water receiving box 3 has a long and narrow structure and is arranged along the front and rear direction of the cabinet 12. The long and narrow structure of the water receiving box 3 can reduce the width occupied by the water receiving box 3, thereby improving the space utilization of the cooking cavity 16.

[0124] Optionally, the water receiving box 3 has a long strip structure, with support bars 52 supporting it on three sides. This ensures the installation stability of the water receiving box 3.

[0125] Optionally, such as Figure 2 and Figure 8 As shown, the heating device 2 includes a heating element 22, which is installed on the top of the housing 12.

[0126] In this embodiment, the heating device 2 can be a variety of heating methods, such as infrared heating, thermal radiation heating, or electromagnetic heating. For example, a heating element 22 can be installed on the top of the cooking cavity 16 to heat the food. At this time, the water tank assembly 4 can be installed on the outer top of the housing 12, and the water receiving box 3 can be positioned close to the top of the cooking cavity 16, so that the heating element 22 can be used to heat the water in the water receiving box 3 into steam.

[0127] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 8As shown, the steam cooking appliance also includes: a water tank assembly 4, which is installed outside the cooking chamber 16 and is used to supply water to the water receiving box 3; along the height direction of the body 12, the water tank assembly 4 is located above the location of the water receiving box 3.

[0128] In this embodiment, when it is necessary to add water to the food, water can be added to the water tank assembly 4. The water in the water tank assembly 4 can flow into the water receiving box 3. In this way, during the cooking process, the water in the water receiving box 3 can be heated into steam to replenish the water to the food.

[0129] The water tank assembly 4 is detachably installed on the tank body 12. The detachment of the water tank assembly 4 facilitates the addition of water and cleaning of the water tank assembly 4.

[0130] In any of the above embodiments, optionally, the water tank assembly 4 is located above the water receiving box 3 along the height direction of the tank body 12.

[0131] In this embodiment, the water tank assembly 4 is set relatively high, while the water receiving box 3 is set relatively low. This allows the water in the water tank assembly 4 to fall under the influence of gravity, making the water flow more smoothly. This reduces the reliance on water pumps and electrical controls, thereby simplifying the product structure and reducing product costs.

[0132] In any of the above embodiments, water in the water tank assembly 4 can optionally flow into the water receiving box 3 under the action of gravity.

[0133] In this embodiment, there is no power equipment between the water tank assembly 4 and the water receiving box 3. The water in the water tank assembly 4 flows into the water receiving box 3 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components, which makes the entire water circuit structure very simple.

[0134] In this type of structure, water does not need to be filled in the water tank assembly 4 when it is not necessary to add water to the food.

[0135] In any of the above embodiments, optionally, as Figure 2 , Figure 4 and Figure 5 As shown, the water receiving box 3 includes a water receiving trough 34. The steam cooking appliance also includes: a connector 7, disposed on the housing 12, with its outlet end located above the water receiving trough 34 along the height direction of the housing 12; and a connecting pipe 8, used to connect the water tank assembly 4 and the connector 7, so as to transport water in the water tank assembly 4 to the water receiving trough 34 through the connecting pipe 8 and the connector 7. Further, the outlet end of the connector 7 is located inside the cooking cavity 16 and protrudes from the inner wall of the cooking cavity 16.

[0136] In this embodiment, the water receiving box 3 is a water receiving trough 34 with an open top. A connector 7 is installed on the housing 12, corresponding to the top of the water receiving trough 34, allowing water in the connector 7 to fall into the water receiving trough 34 under gravity. Simultaneously, steam generated by heating in the water receiving trough 34 can be directly discharged from the opening. This structure simplifies the design of the water receiving box 3, facilitating its processing and cleaning.

[0137] Meanwhile, to ensure water flow between the water tank assembly 4 and the water receiving box 3, a connector 7 is provided on the water receiving box 3 or the tank body 12, and a connecting pipe 8 is installed on the tank body 12. Water in the water tank assembly 4 can be transported to the water receiving box 3 through the connecting pipe 8 and the connector 7. This structure, by directly transporting water to the water receiving box 3 through the connecting pipe 8, can guide the water and prevent it from flowing to other places. At the same time, it can also prevent water from falling directly from a height, thereby reducing water flow noise.

[0138] The outlet end of connector 7 is located inside the cooking cavity 16 and protrudes from the inner wall of the cooking cavity 16. This guides the water flowing out of the outlet end of connector 7 away from the inner wall of the cooking cavity 16, preventing it from flowing along the inner wall. This allows the water flowing out of the outlet end of connector 7 to flow into the water collection box 3. This prevents water from flowing to other parts of the cooking cavity 16 and affecting the cooking of the product when water is supplied to the water collection box 3. This also ensures that there is no obvious turbulence at the outlet of connector 7, thus ensuring the cleanliness of other parts of the cooking cavity 16 and preventing other parts of the cooking cavity 16 from getting wet.

[0139] In any of the above embodiments, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the water tank assembly 4 includes a water outlet channel 44, and the steam cooking appliance also includes: a mounting housing 9, which includes a water storage tank 94 and a drain outlet 90 that are connected to each other. The water storage tank 94 is set corresponding to the water outlet channel 44 and is used to receive water from the water outlet channel 44. The drain outlet 90 is connected to the water receiving box 3, and the water in the water storage tank 94 can be discharged into the water receiving box 3 through the drain outlet 90.

[0140] In this embodiment, a water storage tank 94 is provided on the housing 9. After the water tank assembly 4 is installed, the water outlet channel 44 of the water tank assembly 4 is positioned corresponding to the water storage tank 94. Water discharged from the water outlet channel 44 can first enter the water storage tank 94, and then be discharged from the water storage tank 94 into the water receiving box 3. This design, with the water storage tank 94 provided for the water tank assembly 4, creates a large buffer area at the water outlet of the water tank assembly 4. When the water flow in the water tank assembly 4 is large or rapid, the water can be stored in the storage chamber to buffer the impact of the falling water, allowing the water to enter the cooking chamber 16 at a relatively stable flow rate. This avoids water splashing when the water flow is large and enters the water receiving box 3. Furthermore, the buffering effect of the water flow by the water storage tank 94 also prevents water from overflowing from the water tank assembly 4 and spilling onto other parts of the product, or even overflowing from the front end of the water tank assembly 4, when the water flow is obstructed.

[0141] For example, when water is added directly to the water tank assembly 4 without removing it, the water flow rate is very high. This water flow has a strong impact force, which can easily cause instability in the water flow output from the water tank assembly 4, leading to splashing. Furthermore, it can also cause water to overflow due to insufficient drainage. This application effectively solves the problems of unstable water flow, splashing, and overflow caused by adding a water storage tank 94 at the water outlet channel 44.

[0142] Furthermore, this structure, with its mounting housing 9, allows the housing to be connected to the water receiving box 3 during use, eliminating the need for the water tank assembly 4 to be directly connected to the water receiving box 3. This eliminates the need for any pipe connections during installation and removal of the water tank assembly 4, making it very convenient to disassemble and reassemble the water tank assembly 4. This also makes it easier to remove the water tank assembly 4 for cleaning or adding water.

[0143] In any of the above embodiments, optionally, as Figure 3 As shown, the inner bottom wall of the water storage tank 94 gradually decreases from a position far from the drain outlet 90 to a position close to the drain outlet 90.

[0144] In this embodiment, after water is added to the water tank assembly 4, the water in the water tank assembly 4 can enter the water storage tank 94 through the water outlet 44. The inner bottom wall of the water storage tank 94 gradually decreases from other positions to the drain outlet 90. In this way, when there is less water in the water storage tank 94, the water can gather at the water outlet of the water storage tank 94, making it easier to drain the water in the water storage tank 94. This can prevent water from remaining in the water storage tank 94 and reduce the amount of residual water in the water storage tank 94.

[0145] In any of the above embodiments, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the mounting housing 9 includes a mounting cavity 92, one end of which is provided with a first mounting port 99. The water tank assembly 4 is detachably mounted on the mounting housing 9, and the water tank assembly 4 can move relative to the mounting housing 9 between a locked position and an unlocked position. In the locked position, the water tank assembly 4 is located inside the mounting cavity 92. In the unlocked position, a part of the water tank assembly 4 is located outside the mounting cavity 92, and the other part of the water tank assembly 4 is located inside the mounting cavity 92. When the water tank assembly 4 is in the locked position, along the height direction of the housing 12, the outlet of the water outlet channel 44 is located above the water storage tank 94, so that the water in the water tank assembly 4 can flow into the water storage tank 94 under the action of gravity.

[0146] In these embodiments, the mounting housing 9 is used to support the mounting water tank assembly 4. During installation, the mounting housing 9 can be fixed to the housing 12 or the like of a steam cooking appliance, and then the water tank assembly 4 can be detachably installed inside the mounting housing 9. This allows the water tank assembly 4 to be removed separately, making it convenient to remove the water tank assembly 4 from the product for cleaning and adding water.

[0147] Meanwhile, when the water tank assembly 4 is installed on the mounting housing 9, it can move between an unlocked position and a locked position relative to the mounting housing 9. That is, the water tank assembly 4 has two states on the mounting housing 9. The first is the unlocked state, where the water tank assembly 4 can be removed from the mounting housing 9 for operations such as adding water and cleaning. The second is the locked state, where the water tank assembly 4 is locked and completely contained within the mounting cavity 92, preventing it from being removed from the mounting housing 9. This ensures the stability of the water tank assembly 4 on the mounting housing 9 during product operation.

[0148] When the water tank assembly 4 is in the unlocked position, at least a portion of the water tank assembly 4 is outside the mounting cavity 92, which makes it easier for the user to remove the water tank assembly 4 and improves the ease of disassembly and assembly of the water tank assembly 4.

[0149] Meanwhile, when the water tank assembly 4 is in the locked position, the outlet of the water tank assembly 4 is directly located above the water storage tank 94, so that there is no obstruction at the outlet of the water tank assembly 4. This ensures that the water in the water tank assembly 4 can enter the water storage tank 94 as quickly as possible under the action of gravity.

[0150] Furthermore, with this structure, during installation, the water tank assembly 4 only needs to be placed inside the mounting housing 9, and during disassembly, the water tank assembly 4 can be directly removed. In other words, no additional pipe connection is required when installing and disassembling the water tank assembly 4, thus ensuring the ease of installation and disassembly of the water tank assembly 4.

[0151] In this design, along the height of the steam cooking appliance, the water outlet 44 is located above the water storage tank 94, which in turn is located above the water receiving box 3. This arrangement causes the water outlet 44, drain outlet 90, and water receiving box 3 to gradually decrease in height. This allows water to flow sequentially from the water outlet 44 into the water storage tank 94 under the influence of gravity, and then from the drain outlet 90 of the water storage tank 94 into the water receiving box 3. Thus, the water in the water tank assembly 4 can flow into the water receiving box 3 purely by gravity. With this structure, water in the water tank assembly 4 can flow into the water receiving box 3 under the influence of gravity. That is, there is no power equipment between the water tank assembly 4 and the water receiving box 3. The water in the water tank assembly 4 flows into the water receiving box 3 purely by gravity. In this way, the water filling operation can be achieved simply through the mechanical structure. There is no need to set up a water pump or rely on any electronic control components. This reduces the dependence of the water tank assembly on water pumps and electronic control, thereby simplifying the product structure and reducing the product cost.

[0152] In any of the above embodiments, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the mounting cavity 92 includes a first inner wall surface 922 and a second inner wall surface 924. The first inner wall surface 922 is adapted to the shape of the water tank assembly 4, and the second inner wall surface 924 is recessed towards the outside of the mounting cavity 92 to form a water storage tank 94.

[0153] In these embodiments, the water tank assembly 4 is installed inside the mounting housing 9, and the shape and size of a portion of the inner wall of the mounting cavity 92 are consistent with the housing of the water tank assembly 4. This allows the water tank assembly 4 to be installed precisely inside the mounting housing 9, ensuring the compatibility between the water tank assembly 4 and the mounting housing 9. This enables better positioning and installation of the water tank assembly 4 through the mounting housing 9.

[0154] Simultaneously, the lower inner wall of the rear part of the mounting cavity 92 can be recessed downwards to form the required water storage tank 94, thereby facilitating the buffering of water output from the water tank assembly 4. In this structure, the mounting area of ​​the water tank assembly 4 and the water storage tank 94 are set together, allowing the outlet of the water tank assembly 4 and the water storage tank 94 to be directly connected. This ensures the fitting accuracy between the water tank assembly 4 and the water storage tank 94, making the water flow smoother and preventing the water tank assembly 4 from being misaligned due to improper installation.

[0155] In any of the above embodiments, optionally, the mounting housing 9 includes a bottom shell and a top cover, the bottom shell and the top cover forming a mounting cavity 92, and a portion of the bottom shell is bent away from the top cover to form a water storage tank 94.

[0156] In these embodiments, the mounting housing 9 is formed by a bottom shell and a top cover. A portion of the bottom shell is bent to form a water storage tank 94; that is, a portion of the bottom shell is sunken to form the water storage tank 94. This method of forming the water storage tank 94 is relatively simple, making the mounting housing 9 easier to manufacture, thereby reducing the manufacturing cost of the mounting housing 9.

[0157] Of course, in other solutions, ribs can be formed inside the mounting housing 9 to form a water storage tank 94, or the mounting housing 9 can be made thicker overall, and then a portion of the wall thickness can be removed to form the water storage tank 94.

[0158] In any of the above embodiments, optionally, as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the steam cooking appliance also includes: a first limiting member 98, installed on the mounting housing 9; a second limiting member 402, disposed on the water tank assembly 4; when the water tank assembly 4 is in the locked position within the mounting cavity 92, the first limiting member 98 and the second limiting member 402 mutually limit each other to lock the water tank assembly 4; when the water tank assembly 4 is in the locked position within the mounting cavity 92, pressing the water tank assembly 4 into the mounting cavity 92 can release the limitation between the first limiting member 98 and the second limiting member 402 to unlock the water tank assembly 4; and an elastic member 49, installed between the water tank assembly 4 and the mounting housing 9, for moving the water tank assembly 4 to the unlocked position after the water tank assembly 4 is unlocked.

[0159] In these embodiments, the water tank assembly 4 and the mounting housing 9 can be locked and unlocked via a first limiting structure and a second limiting member 402. After the water tank assembly 4 is unlocked, it can be removed from the mounting housing 9 for adding water, cleaning, or repair / replacement. When the water tank assembly 4 is locked, the fit between it and the mounting housing 9 is good, preventing the water tank assembly 4 from easily shaking and slipping out of the mounting housing 9. Furthermore, with this structure, installing the water tank assembly 4 only requires pushing it into the mounting housing 9, and removing it involves pressing it. The elastic member 49 then releases the water tank assembly 4, allowing it to be detached from the product for adding water or cleaning. This structure eliminates the need for a motor or ejector device for disassembly, simplifying the structure and reducing the cost of the water tank assembly 4. In addition, in this structure, the water tank assembly 4 itself is provided with a second limiting member 402, so that the elastic member 49 can directly act on the water tank assembly 4 itself, thereby limiting the water tank assembly 4 directly through the first limiting structure, making the limiting of the water tank assembly 4 more reliable, and also making the water tank assembly 4 more securely installed in the mounting shell 9, so that the water tank assembly 4 is not easy to loosen.

[0160] Furthermore, this design integrates the mechanism for driving the water tank assembly 4 to rebound directly into the water tank assembly 4 and the mounting housing 9, simplifying the overall structure of the water tank assembly 4 and thus reducing product costs. In this structure, the water tank assembly 4 itself acts as the rebound component, making the pressing and ejection of the water tank assembly 4 more reliable.

[0161] In these embodiments, such as Figure 9 and Figure 11 As shown, the second limiting member 402 is used to limit the position of the water tank assembly 4 within the mounting housing 9.

[0162] Optionally, the second limiting member 402 and the water tank shell 40 are an integral structure.

[0163] In these embodiments, the second limiting member 402 can be a protruding structure or a recessed structure on the water tank outer shell 40. The second limiting member 402 and the water tank outer shell 40 are an integral structure, resulting in higher connection strength and better reliability. Of course, in other solutions, the second limiting member 402 and the water tank outer shell 40 can be separately provided, and then the second limiting member 402 can be detachably installed on the water tank outer shell 40.

[0164] In any of the above embodiments, optionally, when the water tank assembly 4 is in the locked state, the elastic member 49 is in the compressed state. After the water tank assembly 4 is unlocked, the elastic member 49 can extend to push a part of the water tank assembly 4 out of the mounting housing 9 and move the valve assembly 48 from the second position to the first position to close the water outlet channel 44.

[0165] In these embodiments, when the water tank assembly 4 is in the locked state, the elastic member 49 is in the compressed state. When the water tank assembly 4 is in the unlocked state, the elastic member 49 can extend to push the water tank assembly 4 out of the mounting housing 9. At the same time, after the water tank assembly 4 extends out of the mounting housing 9, the push rod 96 separates from the water outlet channel 44, and the valve assembly 48 returns to the second position under the action of the elastic member 49, thereby closing the water outlet channel 44.

[0166] Of course, in other solutions, when the water tank assembly 4 is in the locked state, the elastic element 49 can also be set to the extended state.

[0167] In any of the above embodiments, optionally, as Figure 3 and Figure 9 As shown, the water tank assembly 4 also includes: a valve assembly 48, which is installed at the water outlet channel 44 of the water tank assembly 4 and can move between a first position and a second position; a push rod 96 is provided on the mounting housing 9. When the water tank assembly 4 is in the locked position, the push rod 96 is inserted into the water outlet channel 44 and puts the valve assembly 48 in the first position to open the water outlet channel 44. When the water tank assembly 4 is in the unlocked position or after the water tank assembly 4 is separated from the mounting housing 9, the valve assembly 48 moves from the first position to the second position under the action of the elastic member 49 to close the water outlet channel 44.

[0168] In this embodiment, after the water tank assembly 4 is correctly installed on the mounting housing 9, the valve assembly 48 can be lifted by the push rod 96, thereby opening the water outlet channel 44. After the water tank assembly 4 is unlocked or removed, the valve assembly 48 can automatically return to the second position under the action of the elastic element 49 to close the water outlet channel 44. This makes opening and closing the water tank assembly 4 very convenient. This structure can achieve the opening and closing of the water tank assembly 4 purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly 4 more durable. At the same time, in this structure, the elastic element 49 used for the telescopic installation of the water tank assembly 4 and the elastic element 49 required for the valve assembly 48 are the same part, that is, the pop-out structure of the water tank assembly 4 and the opening and closing structure of the water outlet of the water tank assembly 4 share a single elastic element 49, thereby simplifying the product structure.

[0169] Optionally, such as Figure 3 and Figure 9As shown, the valve assembly 48 includes: a valve stem 482, which is slidably mounted in the water outlet channel 44; and a seal 484, which is mounted on the valve stem 482 and can move with the valve stem 482 to open or seal the water outlet channel 44.

[0170] Optionally, such as Figure 3 As shown, the water outlet channel 44 includes a water outlet. When the valve assembly 48 is in the first position, the seal 484 blocks the water outlet. When the valve assembly 48 is in the second position, the seal 484 opens the water outlet.

[0171] In this embodiment, the seal 484 is disposed within the water outlet channel 44, near the water outlet. When the water tank assembly 4 is not installed on the product, the valve assembly 48 is in the first position, and the seal 484 blocks the water outlet, preventing water in the water tank assembly 4 from draining through the water outlet channel 44. After the water tank assembly 4 is installed, the valve assembly 48 is in the second position. At this time, the seal 484 is positioned away from the water outlet and opens the water outlet, connecting the water outlet and the water inlet. This allows water in the water tank assembly 4 to drain through the water outlet channel 44, facilitating water supply to the steam cooking appliance. With this structure, the seal 484, installed within the water outlet channel 44, can move along the outlet of the water outlet channel 44 when the valve assembly 48 closes the water outlet channel 44. This allows the seal 484 to squeeze out any remaining water in the water outlet channel 44, preventing excessive water residue. This also prevents leakage when the water tank assembly 4 is removed, thus avoiding any impact on the user experience.

[0172] Of course, in other solutions, such as Figure 9 As shown, the seal 484 can also be installed at the water inlet to open or block the water inlet.

[0173] In any of the above embodiments, optionally, as Figure 3 As shown, at least a portion of the water outlet channel 44 is located within the water-receiving cavity 42. The water outlet channel 44 includes an inlet, and the water outlet channel 44 communicates with the water-receiving cavity 42 through the inlet. The inlet is located on the side wall of the portion of the water outlet channel 44 located within the water-receiving cavity 42. This arrangement allows the inlet to be closer to the outlet, thereby shortening the movement distance of the seal 484 and making it easier for the seal 484 to open the outlet and connect the outlet and inlet.

[0174] In any of the above embodiments, optionally, as Figure 1 , Figure 2 and Figure 8As shown, the steam cooking appliance includes a door 14. A cooking inlet 122 and a first mounting opening 99 are provided at a first end along a first direction. The door 14 is installed at the first end of the housing 12 to open or close the cooking inlet 122. The water tank assembly 4 can be pulled and installed onto the housing 12 along the first direction via the first mounting opening 99. Further, as... Figure 3 and Figure 9 As shown, the water tank assembly 4 includes: a water tank shell 40, which includes a water-containing cavity 42 and a water inlet 46 communicating with the water-containing cavity 42, the water inlet 46 being disposed at one end of the water tank shell 40 along a first direction; a cover 47, which is detachably mounted on the water tank shell 40 to open or close the water inlet 46; and a sealing ring 41, which is disposed between the water tank shell 40 and the cover 47 to seal the gap between the water tank shell 40 and the cover 47.

[0175] In this embodiment, the first mounting port 99 and the cooking inlet 122 are located on the same side, that is, the water tank assembly 4 is installed on the side of the housing 12 where the door 14 is located, for example, the water tank assembly 4 is located on the front side of the housing 12. Simultaneously, the water tank assembly 4 can also be installed onto the housing 12 along the front side, and the water tank assembly 4 can be pulled out in the front-back direction to achieve the assembly and disassembly of the water tank assembly 4. Furthermore, the water tank assembly 4 is also placed front-back on the housing 12, that is, the water tank assembly 4 is installed horizontally on the housing 12, not vertically. This reduces the space occupied by the height of the water tank assembly 4, preventing the entire product from being too tall, thus allowing the water tank assembly 4 to be installed on the top of the cooking cavity 16, thereby providing conditions for the water tank assembly 4 to use gravity for water release.

[0176] The water tank assembly 4 specifically includes a water tank shell 40 and a cover 47. The water tank shell 40 is provided with a water inlet 46, and the cover 47 is detachably installed on the water inlet 46 of the water tank shell 40. At the same time, in order to ensure a seal between the water tank shell 40 and the cover 47, a sealing ring 41 is also provided between the two. The sealing ring 41 can make the two seal together, thereby preventing water leakage from the water tank assembly 4.

[0177] In other related solutions, the water tank assembly 4 on the oven has a water inlet directly installed on the side wall of the water tank outer shell 40 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 47 is specifically designed. This allows for easy cleaning of the water tank assembly 4 by opening the cover 47, ensuring the cleanliness of the water tank assembly 4. Furthermore, this design allows users to easily inspect the inside of the water tank assembly 4 for dirt and grime, making it easier to detect dirt and grime and clean the water tank assembly 4 promptly. This gives users greater peace of mind when using the water tank assembly 4.

[0178] Specifically, the first direction can be the front-to-back direction of the tank body 12. In this case, the water tank assembly 4 can be disassembled and assembled from the front side of the tank body 12. The cover 47 and the outer shell 40 of the water tank assembly 4 are also assembled along the front-to-back direction. This means that the water tank assembly 4 is installed horizontally on the tank body 12, rather than vertically. This reduces the space occupied by the height of the water tank assembly 4, preventing the entire product from becoming too tall.

[0179] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the cabinet 12 includes an inner liner 120, which forms a cooking cavity 16, and a water tank assembly 4 is installed above the inner liner 120.

[0180] In this embodiment, the water tank assembly 4 is installed relatively high to facilitate water discharge using gravity. Furthermore, this design allows for efficient use of the product's height, thereby reducing its width and footprint, and making it easier to store.

[0181] In any of the above embodiments, optionally, as Figure 2 As shown, the housing 12 includes a first part and a second part. The door 14 is installed on the first part. Along the height direction of the housing 12, the second part is located above the first part, and the water tank assembly 4 is installed on the second part.

[0182] In this embodiment, the door 14 and the water tank assembly 4 are installed in different areas of the housing 12, so that the water tank assembly 4 can be exposed outside the door 14, so that the door 14 can be added without opening it, thus making it convenient to add water during the cooking process.

[0183] Among them, the sealing element 484 is a sealing ring 41, and one or more sealing ribs are provided on the outer side wall of the sealing ring 41, and one or more sealing ribs are in sealing contact with the inner side wall of the water outlet channel 44.

[0184] The heating device 2 is located at the top of the cooking cavity 16. It can heat the water tank 3 and also heat the food in the cooking cavity 16. In other words, this application uses the heat source on the existing product for heating, without the need to set up a separate heating structure for the water tank. This simplifies the product structure, reduces the cost of product upgrades, and makes it easier for the product to be promoted and updated.

[0185] To ensure the overall heating effect of the steam cooking appliance, additional heating devices 2 can be installed. For example, additional heating devices 2 can be installed at the bottom or sides of the cooking cavity 16 to ensure the overall heating effect of the product on the food.

[0186] In any of the above embodiments, optionally, as Figure 9 , Figure 11 and Figure 12 As shown, the second limiting member 402 includes a guide slide 4022, and the guide slide 4022 includes a limiting groove. Figure 10 As shown, the first limiting member 98 includes a movable member 982, which is mounted on the mounting housing 9, and a portion of the movable member 982 is located within the guide slide 4022. When the water tank assembly 4 is installed into the mounting cavity 92, at least a portion of the movable member 982 can move from the first end of the guide slide 4022 to the limiting groove and be limited in the limiting groove. When the water tank assembly 4 is located in the mounting cavity 92, pressing the water tank assembly 4 into the mounting cavity 92 allows at least a portion of the movable member 982 to move towards the second end of the guide slide 4022 until it separates from the limiting groove, thereby unlocking the water tank assembly 4.

[0187] In these embodiments, the first limiting member 98 includes a movable member 982, which may be a rotating member or a sliding member. When the water tank assembly 4 is installed in the mounting housing 9 or removed from the mounting housing 9, the movable member 982 can move relative to the guide slide 4022. A limiting groove is provided in the guide slide 4022, which restricts the movable member 982 to ensure that the water tank assembly 4 can be locked in the third position. Subsequently, when it is necessary to remove the water tank assembly 4, the water tank assembly 4 can be pressed into the mounting housing 9 to move it inward. This allows the movable member 982 to move again to the position separated from the limiting groove, thereby limiting the water tank assembly 4 and placing it in an unlocked state. After the water tank assembly 4 is unlocked, the elastic element 49 can rebound, thereby pushing the water tank assembly 4 to move a certain distance out of the mounting housing 9, so as to realize the automatic ejection of the water tank, making it convenient for the user to disassemble the water tank assembly 4 for cleaning, adding water or maintenance.

[0188] In this configuration, when the water tank assembly 4 is pulled out of the mounting housing 9, the movable part 982 can continue to slide as before, instead of sliding back. This design ensures that the movement paths of the movable part 982 are not the same when the water tank assembly 4 is inserted into the mounting housing 9 and when it is pulled out of the mounting housing 9, thereby making the locking and unlocking engagement between the movable part 982 and the guide slide 4022 more reliable.

[0189] Conversely, when the water tank assembly 4 is unlocked, at least a portion of the movable part 982 can also move back toward the first end of the guide slide 4022 until the movable part 982 separates from the limiting groove.

[0190] In any of the above embodiments, optionally, as Figure 10 As shown, the movable part 982 includes a slider that can slide along the guide slide 4022 and is limited to the limiting groove when the water tank assembly 4 is located in the mounting cavity 92.

[0191] In these embodiments, the movable component 982 includes a sliding component. The sliding component slides along the guide slide 4022, allowing the water tank assembly 4 to be inserted and removed. Simultaneously, after the water tank assembly 4 is inserted and installed in place, i.e., when the water tank assembly 4 is installed into the mounting cavity 92, the sliding component can be better engaged in the limiting groove, thus preventing the sliding component from sliding and locking the water tank assembly 4. When it is necessary to remove the water tank assembly 4 again, the water tank assembly 4 can be pressed inward to retract the limiting groove, allowing the sliding component to slide out of the limiting groove along the second guide surface. This releases the limiting fit between the sliding component and the limiting groove, freeing the water tank assembly 4 and facilitating its removal for heating, adding water, cleaning, or repair / replacement.

[0192] Among them, such as Figure 1 As shown, the first end of the housing 12 along the first direction is provided with a second mounting port 124. The second mounting port 124 is provided correspondingly to the first mounting port 99 and avoids the first mounting port 99. For example, the end of the mounting shell 9 with the first mounting port 99 can be provided in the second mounting port 124 so that the water tank assembly 4 can be inserted into the mounting shell 9 from the front side of the housing 12.

[0193] In any of the above embodiments, the steam cooking appliance may optionally include an oven and / or a steamer. Of course, the steam cooking appliance may also be other devices that require a water tank.

[0194] in, Figure 12 The arrows in the diagram indicate the movement trajectory of the moving part 982 within the guide slide 4022.

[0195] The following example of a steam oven will be used to further illustrate the steam cooking appliance in this application.

[0196] In related solutions, steam ovens with humidification functions typically have an external water tank, along with an external steam generator, which actively generates steam by heating the water.

[0197] This embodiment proposes a steam oven with a built-in water tank and humidification function. In this oven, the water tank is built into the cavity, and passive heating is achieved using heat generated by a heating element within the cavity. The water tank is essentially a water basin, allowing for easy placement and retrieval by the user, facilitating water addition and maintenance. It is placed on top of a shelf without affecting the overall volume of the cavity.

[0198] In this structure, the water tank is combined with the internal shelves of the cavity to store water, and the heat from the heating element inside the cavity is used for passive heating to generate water vapor.

[0199] Meanwhile, this structure features a detachable water tank that is easy to assemble and disassemble, compact in size, and convenient for placement and water filling. It utilizes the existing heating source of existing models for passive heating to generate steam, effectively achieving the product's simple steaming function. Furthermore, the integrated opening design of the water tank facilitates cleaning and maintenance. Positioned on top of the shelf, close to the heating element at the top of the cavity, it enhances heat acquisition and achieves the automatic simple steaming effect. Additionally, the top of the shelf has mounting slots to support and accommodate the water tank, ensuring its load-bearing and secure function.

[0200] In one specific embodiment, the water tank can be placed on the left or right shelves, and the specific location is not limited;

[0201] In one specific embodiment, the shelf can be integrated with the sink, and the shelf can be disassembled for unified assembly and disassembly. Of course, the shelf and the sink can also be installed separately, and each can be assembled and disassembled independently.

[0202] In one specific embodiment, the water tank can be fixed to the heating element at the top of the cavity, eliminating the need for assembly with the shelf.

[0203] In one specific embodiment, a soft-plug valve can be installed at the bottom of the water tank, which can empty the residual water in the water tank without disassembly, eliminating the need for daily maintenance.

[0204] The enclosure includes an inner liner and a shell. The inner liner is installed inside the shell, and a space is provided between the outer wall of the inner liner and the inner wall of the shell to accommodate the outer shell and water tank assembly. The front of the shell has a front opening, through which the inner liner forms a cooking cavity. A second mounting port is also provided on the front of the shell for inserting the water tank assembly. The water tank assembly is inserted through this second mounting port between the inner liner and the shell.
