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 proposed steam oven has a water collection trough inside the oven and a water tank assembly outside. A connecting pipe is also installed on the oven to transport water from the water tank assembly to the water collection trough. However, in this proposed design, water exiting from the outlet of the connecting pipe tends to flow along the inner wall of the cooking cavity to other locations, especially when the water flow is low.

[0003] Therefore, designing a steam oven in which water from the outlet of the connecting pipe can flow stably into the water receiving tank and is less likely to flow along the inner wall to other locations has become an urgent problem to be solved. Utility Model Content

[0004] The present invention aims to at least solve the problem in the prior art or related technologies that water output from a steam oven via a connecting pipe can easily flow along the inner wall of the cooking cavity to other locations.

[0005] The first objective of this invention is to provide a water tank device.

[0006] Therefore, the first objective of this invention is to provide a steam cooking appliance.

[0007] To achieve the above objectives, an embodiment of the first aspect of this utility model provides a water tank device for a steam cooking appliance. The steam cooking appliance includes a housing, which includes a cooking cavity. The water tank device includes: a water receiving trough installed inside the cooking cavity; a water tank assembly located outside the cooking cavity; and a connector installed on the water receiving trough or the housing and communicating with the water tank assembly. The outlet end of the connector is provided corresponding to the water receiving trough, and water in the water tank assembly can be transported to the water receiving trough through the connector. The outlet end of the connector is located inside the cooking cavity and protrudes from the inner wall of the cooking cavity.

[0008] In this embodiment, the water tank device can be specifically used in steam cooking appliances such as steam ovens. This water tank device supplies water to the steam cooking appliance, enabling it to generate steam for humidifying the food. The steam cooking appliance includes a housing with a cooking chamber inside, where the food to be cooked can be placed for heating. The water tank device specifically includes a water receiving tank, a water tank assembly, and a connector. The water tank assembly stores water, and the water in the assembly flows into the water receiving tank for timely replenishment. The water in the receiving tank is heated into steam in the cooking chamber to hydrate the food inside. The connector is located on the water receiving tank; water from the water tank assembly first enters the connector and then flows into the receiving tank. With this structure, when water needs to be added to the food, water can be added to the receiving tank through the water tank assembly without opening the cooking chamber.

[0009] Meanwhile, 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 of the connector, preventing it from flowing along the inner wall of the cooking cavity. As a result, the water flowing out of the outlet end of the connector can flow into the water receiving tank. 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 receiving tank. This also ensures that there is no obvious turbulence at the outlet of the connector, thus ensuring the cleanliness of other parts of the cooking cavity and preventing them from getting wet.

[0010] In any of the above embodiments, the water tank device may optionally include a connecting pipe for connecting the water tank assembly and the connector, so as to transport the water in the water tank assembly to the water receiving tank through the connecting pipe and the connector.

[0011] In this embodiment, a connecting pipe can be installed between the connector and the water tank assembly to ensure that water in the water tank assembly can flow to the connector. Through the connecting pipe, water in the water tank assembly can be promptly transported to the receiving tank. This structure, with the connecting pipe, allows for more flexible installation of the water tank assembly, thus facilitating the overall layout of the product. Of course, in other solutions, the connecting pipe can be omitted, and the outlet of the water tank assembly can be directly connected to the connector.

[0012] In addition, by connecting water directly to the water tank through a connecting pipe, 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.

[0013] The connecting pipe can be a separate pipe structure or a channel structure enclosed by the shell structure of the box.

[0014] In any of the above embodiments, optionally, the housing includes a side wall and a top of the bladder that are connected to each other, and a connector is disposed at the connection between the side wall and the top of the bladder.

[0015] In this embodiment, the connector is placed at the connection between the side wall and the top of the inner pot, so that the position of the connector is relatively close to the corner of the box, which can reduce the area occupied by the connector and improve the space utilization rate inside the cooking cavity.

[0016] In any of the above embodiments, optionally, an installation plane is provided at the connection between the side wall and the top of the gallbladder, the installation plane is inclined relative to the height direction of the casing, and the connector is provided on the installation plane.

[0017] In this embodiment, in order to ensure the installation stability of the connector, or to facilitate the processing of the connector, an installation plane can be set at the connection between the side wall and the top of the tank. Then, the required connector can be processed or installed at the installation plane position. This can improve the stability of the connector installation and the stability of the connector when connected to the water tank assembly or connecting pipe.

[0018] In any of the above embodiments, optionally, the box body includes an inner liner that forms a cooking cavity, and the connector includes a water guiding protrusion disposed on the inner wall of the inner liner and a connecting channel that penetrates the inner liner and the water guiding protrusion. The inlet end of the connecting channel is connected to the water tank assembly, and the outlet end of the connecting channel is disposed in a corresponding water receiving tank, so that water at the outlet end of the connecting channel can flow into the water receiving tank.

[0019] In this embodiment, the housing includes an inner liner that forms the cooking cavity. To create a flow-guiding structure on the inner wall of the cooking cavity and prevent water from flowing along it, a water-guiding protrusion is provided on the inner side of the inner liner. A connecting channel is then machined into the inner liner, penetrating the inner liner and the water-guiding protrusion. This forms a connector structure. Because the water-guiding protrusion is directly formed on the inner liner, its connection to the inner liner is more reliable, and its position is more stable, thus preventing the water outlet from wobbling.

[0020] In any of the above embodiments, optionally, the connector is a pipe installed on the box body, and the pipe is detachably connected to the box body or integrally connected; the box body includes an inner liner, the inner liner surrounds the cooking cavity, and the outlet end of the pipe is located inside the cooking cavity and protrudes from the inner wall of the inner liner.

[0021] In this embodiment, the connector is an additionally installed pipe fitting, thus eliminating the need to machine a water-guiding protrusion on the inner liner. This simplifies the structure of the inner liner and reduces its processing cost. Simultaneously, to ensure that the water discharged from the pipe fitting does not flow along the inner wall of the cooking cavity, the outlet end of the pipe fitting can be positioned on the inner wall of the cooking cavity and extend a certain length relative to the inner wall. This allows the water to be accurately guided into the water receiving tank through the pipe fitting, preventing water from flowing along the cooking cavity to other locations.

[0022] In any of the above embodiments, the pipe fitting may optionally be a metal component.

[0023] In this embodiment, using a metal fitting can improve its high-temperature resistance. Since the fitting is partially inserted into the cooking cavity, where the temperature is high, using a metal fitting allows it to withstand the high temperatures in the cooking cavity for a long time without deformation. This can extend the service life of the fitting and also prevent it from melting and deforming, thus avoiding the release of toxic substances.

[0024] In any of the above embodiments, the connector may optionally be a straight connector or a curved connector.

[0025] In this embodiment, the shape of the connector can be reasonably set according to the location of the connector and the water receiving tank. For example, the connector can be set as a straight line, which can make the water flow more smoothly and minimize the material consumption of the connector. Of course, when the distance between the connector and the water receiving tank is far, a bending structure can also be set on the connector to form a curved connector, depending on the actual situation.

[0026] In any of the above embodiments, optionally, the connecting pipe includes a flexible hose, at least a portion of which is mounted on the housing; or the connecting pipe includes a channel structure formed on the housing.

[0027] In this embodiment, the connecting pipe is a flexible hose, making its installation more flexible. Of course, the connecting pipe can also be a channel structure formed by the housing of the box; in this case, there is no need to install additional pipes, thereby reducing the number of parts in the product.

[0028] In any of the above embodiments, the water receiving tank may optionally be detachably installed inside the tank.

[0029] In this embodiment, when it is not necessary to add water to the food, the water tank and water collection trough assembly can be removed from the body to prevent the water tank from drying out. Alternatively, the water tank can be made non-removable; in this case, the water in the water tank assembly can be emptied when it is not necessary to add water to the food.

[0030] In any of the above embodiments, the steam cooking appliance may optionally include: a first bracket installed inside the cooking cavity, and a water tank installed on the first bracket.

[0031] In this embodiment, a first bracket is installed inside the box, and the first bracket is mounted on the inner wall of the box. For example, the first bracket can be installed on the box by means of screws or clips. The water receiving tank is installed on the first bracket, which makes the installation and removal of the water receiving tank more convenient.

[0032] 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 disposed opposite to each other in the width direction, for supporting the food carrier; wherein, the first support is installed on the top of one of the second supports.

[0033] In this embodiment, the second bracket can be used to support and install food carriers such as baking pans. The first bracket is installed on top of the second bracket; that is, in this structure, the water tank and the first bracket are directly installed on the support bracket of the food carrier such as the baking pan. This allows the installation of the water tank to be achieved using the existing brackets inside the box, thereby simplifying the overall product structure and reducing the overall product cost.

[0034] Furthermore, the second bracket is provided with multiple support parts, which are spaced apart along the height direction of the container. The second bracket can install the food carrier at multiple height positions through these support parts. This arrangement allows the installation height of the food carrier to be adjusted, and also allows the two second brackets to support and install multiple food carriers simultaneously.

[0035] In any of the above embodiments, optionally, a flange is provided at the opening of the water receiving tank, and the flange extends from the inside to the outside of the opening; the first bracket includes a support bar, and the water receiving tank is installed on the support bar through the flange.

[0036] In this embodiment, the flange allows for the positioning and installation of the connecting water tank. To ensure the installation of the first bracket with the water tank, a support bar is provided on the first bracket. The support bar can be supported at the bottom of the flange to support the connecting water tank. To ensure the installation stability of the water tank, the shape of the support bar can be adapted to the outer wall of the water tank, and the length of the support bar can be set with reference to the outer perimeter of the water tank.

[0037] For example, when the water receiving trough is long and narrow, the support strip can cover three sides of the trough to ensure its stability. When the water receiving trough is circular or near-circular, the support strip can cover more than a quarter of its circumference.

[0038] In any of the above embodiments, optionally, the water receiving trough is a long strip structure, and the water receiving trough is arranged along the front-rear direction of the cabinet. The long strip structure of the water receiving trough can reduce the width occupied by the water receiving trough, thereby improving the space utilization of the cooking cavity.

[0039] Optionally, the water receiving trough has a long, narrow structure, with support bars on three sides. This ensures the stability of the water receiving trough during installation.

[0040] In any of the above embodiments, optionally, the water tank assembly is mounted on the tank body. By mounting the water tank assembly on the tank body, the water tank assembly and the tank body can form a single unit, thereby facilitating pipe connection operations between the water tank assembly and the connectors. This also makes the overall unit more compact. Of course, in other solutions, the water tank can also be set up independently of the tank body.

[0041] Furthermore, the water tank assembly is installed on top of the tank body, thereby setting the water tank assembly higher to facilitate gravity-based water release.

[0042] In any of the above embodiments, optionally, along the height direction of the tank body, the water tank assembly is located above the location of the water receiving trough, and the water in the water tank assembly can flow into the water receiving trough through the connector under the action of gravity.

[0043] In this embodiment, the water tank assembly is set relatively high, while the water receiving trough 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.

[0044] In this system, water in the water tank flows into the receiving tank under gravity. There is no power source between the water tank and the receiving tank; the water flows into the receiving tank purely by gravity. This allows for water filling via a purely mechanical structure, eliminating the need for a water pump or any electronic components, resulting in a very simple water circuit structure.

[0045] This type of structure allows for the elimination of water tank components when it is not necessary to add water to the food.

[0046] In any of the above embodiments, optionally, the water tank assembly includes a water-containing cavity, a water outlet channel communicating with the water-containing cavity, and a water inlet. Along the height direction of the tank body, the inner bottom wall of the water-containing cavity gradually decreases from the water inlet to the water outlet channel.

[0047] In this embodiment, water can be added to the water tank assembly through the inlet, and the water in the water tank assembly can be discharged through the outlet channel. The inner bottom wall of the water-containing cavity gradually decreases from the inlet to the outlet channel. This allows water to accumulate at the outlet of the water tank assembly when there is little water in it, making it easier for the water to flow out and preventing water from remaining in the water tank assembly, thereby reducing the amount of residual water in the water tank assembly.

[0048] In any of the above embodiments, optionally, the steam cooking appliance further includes: a mounting shell, mounted on a housing, the mounting shell being provided with a placement groove for placing a water tank assembly; the mounting shell is also provided with a water storage tank, the bottom wall of the water storage tank being lower than the bottom wall of the placement groove along the height direction of the housing; when the water tank assembly is installed in the placement groove, the water tank assembly is connected to the water storage tank, and water in the water tank assembly can flow into the water storage tank; a connector is connected to the water storage tank.

[0049] In this embodiment, the mounting housing supports the water tank assembly. The mounting housing comprises two parts: one part forms a placement groove for supporting the water tank assembly, and the other part forms a water storage tank for collecting water discharged from the water tank assembly. Water in the storage tank flows into a receiving tank via a connecting pipe. Because of the mounting housing, the water tank assembly does not need to be connected to connecting pipes, eliminating the need for any pipework during installation and removal. This makes the assembly and disassembly of the water tank assembly very convenient, facilitating cleaning or adding water.

[0050] In any of the above embodiments, optionally, the water tank assembly further includes: a water outlet channel; 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 to open or close the water outlet channel; and a push rod provided on the mounting housing, the push rod being used to position the valve assembly in the first position to open the water outlet channel when the water tank assembly is installed in the placement slot, and the valve assembly in the second position to close the water outlet channel after the water tank assembly is removed from the placement slot.

[0051] 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 removed, the valve assembly can automatically return to the second position to close the water outlet channel. This makes opening and closing the water tank assembly very convenient. This structure allows the water tank assembly to be opened and closed purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly more durable.

[0052] 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.

[0053] 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.

[0054] In any of the above embodiments, optionally, the steam cooking appliance includes a housing, the housing including a cooking chamber, and a cooking chamber inlet and an installation port provided at a first end of the housing along a first direction, the cooking chamber inlet communicating with the cooking chamber. The steam cooking appliance also includes a door installed at the first end of the housing to open or close the cooking chamber inlet, and a water tank assembly that can be pulled and installed onto the housing along the first direction from the installation port; the water tank assembly includes: a water tank shell, the water tank shell including a water-containing chamber and a water inlet communicating with the water-containing chamber, 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.

[0055] In this embodiment, the steam cooking appliance includes a housing and a door. A cooking chamber is provided inside the housing, and the cooking chamber inlet is connected to the housing. The door is installed on the housing and is used to open and close the cooking chamber inlet. The water tank assembly is installed on the side of the housing where the door is located, for example, on 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 a front-back direction for easy assembly and disassembly. Furthermore, the water tank assembly is placed horizontally on the housing, not vertically.

[0056] The cabinet and door together form the outer shell of the entire product, creating a cooking cabinet.

[0057] The water tank assembly specifically includes a water tank shell and a cover. The water tank shell has a water inlet, and the cover can be 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.

[0058] 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.

[0059] The first direction can specifically refer to the front-to-back direction of the tank. For example, the water tank assembly can be disassembled and installed from the front of the tank. The cover and outer shell of the water tank assembly are also assembled along the front-to-back direction, which means that the water tank assembly is installed horizontally on the tank, rather than vertically.

[0060] In any of the above embodiments, optionally, the steam cooking appliance further includes: a heating device installed on the housing for heating the food inside the cooking cavity; the water in the water tank can be heated into steam by the heating device.

[0061] In this embodiment, the water receiving tank is used to store water, and the water in the tank can be heated into steam by the heating device to humidify and replenish the food in the cooking cavity. With this configuration, the water receiving tank can be heated directly using the product's existing heating device, 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 receiving tank.

[0062] Optionally, the heating device includes a heating element mounted on the top of the enclosure.

[0063] 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 tray can be positioned close to the top of the cooking cavity, so that the heating element can heat the water in the water receiving tray into steam.

[0064] In any of the above embodiments, the steam cooking appliance may optionally include an oven. Of course, the steam cooking appliance may also be other devices that require a water tank.

[0065] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0079] 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.

[0080] 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.

[0081] The following reference Figures 1 to 10 The present application describes the water tank device and steam cooking appliance provided in the embodiments.

[0082] like Figure 1 , Figure 4 and Figure 8 As shown, an embodiment of the first aspect of this utility model provides a water tank device for a steam cooking appliance. The steam cooking appliance includes a housing 12, which includes a cooking cavity 16. The water tank device includes: a water receiving trough 3, installed inside the cooking cavity 16; a water tank assembly 4, located outside the cooking cavity 16; and a connector 7, installed on the water receiving trough 3 or the housing 12 and communicating with the water tank assembly 4. The outlet end of the connector 7 is provided corresponding to the water receiving trough 3, and water in the water tank assembly 4 can be transported to the water receiving trough 3 through the connector 7. 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.

[0083] In this embodiment, the water tank device can be specifically used in steam cooking appliances such as steam ovens. This water tank device supplies water to the steam cooking appliance, enabling it to generate steam for humidifying the food. The steam cooking appliance includes a housing 12, within which a cooking chamber 16 is provided. The food to be cooked can be placed in the cooking chamber 16 for heating. The water tank device specifically includes a water receiving tank 3, a water tank assembly 4, and a connector 7. The water tank assembly 4 stores water, and the water in the water tank assembly 4 flows into the water receiving tank 3 to replenish it. The water in the water receiving tank 3 can be heated into steam in the cooking chamber 16 to humidify the food inside. The connector 7 is located on the water receiving tank 3, and the water in the water tank assembly 4 first enters the connector 7 and then flows from the connector 7 into the water receiving tank 3. With this structure, when water needs to be added to the ingredients, water can be added to the water tank 3 through the water tank assembly 4, so that water can be added to the water tank 3 without opening the cooking cavity 16.

[0084] At the same time, such as Figure 8 As shown, the outlet end of connector 7 is located inside the cooking cavity 16 and protrudes from the inner wall of the cooking cavity 16. In this way, the water flowing out of the outlet end of connector 7 can be guided away from the inner wall of the cooking cavity 16 and will not flow along the inner wall of the cooking cavity 16. This allows the water flowing out of the outlet end of connector 7 to flow into the water receiving tank 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 receiving tank 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.

[0085] In any of the above embodiments, optionally, as Figure 1 and Figure 4 As shown, the water tank device also includes a connecting pipe 8 for connecting the water tank assembly 4 and the connector 7, so as to transport the water in the water tank assembly 4 to the water receiving tank 3 through the connecting pipe 8 and the connector 7.

[0086] In this embodiment, to ensure that the water in the water tank assembly 4 can flow to the connector 7, a connecting pipe 8 can be installed between the connector 7 and the water tank assembly 4. Through the connecting pipe 8, the water in the water tank assembly 4 can be promptly transported to the water receiving tank 3. This structure, by including the connecting pipe 8, allows for more flexible installation of the water tank assembly 4, thus facilitating the overall layout of the product. Of course, in other solutions, the connecting pipe 8 can be omitted, and the outlet of the water tank assembly 4 can be directly connected to the connector 7.

[0087] In addition, by directly conveying water to the water receiving tank 3 through the connecting pipe 8, 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.

[0088] The connecting pipe 8 can be a separate pipe structure or a channel structure enclosed by the shell structure of the box 12.

[0089] In any of the above embodiments, optionally, as Figure 2 and Figure 10 As shown, the housing 12 includes a side wall 1262 and a top 1264 of the bladder that are connected to each other, and the connector 7 is disposed at the connection between the side wall 1262 and the top 1264 of the bladder.

[0090] In this embodiment, the connector 7 is located at the connection between the side wall 1262 and the top 1264 of the inner pot, so that the position of the connector 7 is relatively close to the corner of the box 12. This reduces the area occupied by the connector 7 and improves the space utilization rate inside the cooking cavity 16.

[0091] In any of the above embodiments, optionally, as Figure 10 As shown, a mounting plane 1266 is provided at the connection between the side wall 1262 and the top 1264 of the bladder. The mounting plane 1266 is inclined relative to the height direction of the housing 12, and the connector 7 is provided on the mounting plane 1266.

[0092] In this embodiment, in order to ensure the installation stability of the connector 7, or to facilitate the processing of the connector 7, an installation plane 1266 can be provided at the connection between the side wall 1262 and the top 1264 of the tank. Then, the required connector 7 can be processed or installed at the installation plane 1266. This can improve the stability of the connector 7 and also improve the stability of the connector 7 when connected to the water tank assembly 4 or the connecting pipe 8.

[0093] In any of the above embodiments, optionally, as Figure 10 As shown, the cabinet 12 includes an inner liner 126, which forms a cooking cavity 16. The connector 7 includes a water-guiding protrusion 72 disposed on the inner wall of the inner liner 126 and a connecting channel 74 passing through the inner liner 126 and the water-guiding protrusion 72. The inlet end of the connecting channel 74 is connected to the water tank assembly 4, and the outlet end of the connecting channel 74 is disposed corresponding to the water receiving tank 3. Water from the outlet end of the connecting channel 74 can flow into the water receiving tank 3.

[0094] In this embodiment, the housing 12 includes an inner liner 126, which forms the cooking cavity 16. To create a flow-guiding structure on the inner wall of the cooking cavity 16 and prevent water from flowing along it, a water-guiding protrusion 72 is provided on the inner side of the inner liner 126. A connecting channel 74 is then machined into the inner liner 126, penetrating the inner liner 126 and the water-guiding protrusion 72. This forms a connector 7 structure. Because the water-guiding protrusion 72 is directly formed on the inner liner 126, its connection to the inner liner 126 is more reliable, and its position is more stable, thus preventing the water outlet from shaking.

[0095] In any of the above embodiments, optionally, as Figure 4 and Figure 8 As shown, connector 7 is a pipe fitting 76 installed on the box body 12. The pipe fitting 76 is detachably connected to the box body 12 or integrally connected. The box body 12 includes an inner liner 126, which forms a cooking cavity 16. The outlet end of the pipe fitting 76 is located inside the cooking cavity 16 and protrudes from the inner wall of the inner liner 126.

[0096] In this embodiment, the connector 7 is an additionally installed pipe 76, thus eliminating the need to machine a water-guiding protrusion 72 on the inner liner 126. This simplifies the structure of the inner liner 126 and reduces its processing cost. Simultaneously, to ensure that the water discharged from the pipe 76 does not flow along the inner wall of the cooking cavity 16, the outlet end of the pipe 76 can be positioned on the inner wall of the cooking cavity 16 and extend a certain length relative to the inner wall. This allows the water to be accurately guided into the water receiving tank 3 through the pipe 76, preventing water from flowing along the cooking cavity 16 to other locations.

[0097] In any of the above embodiments, the fitting 76 may optionally be a metal component.

[0098] In this embodiment, the fitting 76 is made of metal, which can improve the high temperature resistance of the fitting 76. Since the fitting 76 is partially inserted into the cooking cavity 16, and the temperature in the cooking cavity 16 is high, making the fitting 76 of metal allows the fitting 76 to withstand the high temperature in the cooking cavity 16 for a long time without deformation. This can improve the service life of the fitting 76 and also prevent the fitting 76 from melting and deforming and releasing toxic substances.

[0099] In any of the above embodiments, the connector 7 may optionally be a straight connector or a curved connector.

[0100] In this embodiment, the shape of the connector 7 can be reasonably set according to the position of the connector 7 and the position of the water receiving tank 3. For example, the connector 7 can be set as a straight line, so that the water flow can be smoother and the material consumption of the connector 7 can be minimized. Of course, when the distance between the connector 7 and the water receiving tank 3 is far, a bending structure can also be set on the connector 7 to form a curved connector 7, depending on the actual situation.

[0101] In any of the above embodiments, optionally, as Figure 4 and Figure 8 As shown, the connecting pipe 8 includes a flexible hose 82, at least a portion of which is mounted on the housing 12; or the connecting pipe 8 includes a channel structure formed on the housing 12.

[0102] In this embodiment, the connecting pipe 8 is a flexible hose 82, which makes the installation of the connecting pipe 8 more flexible. Of course, the connecting pipe 8 can also be a channel structure formed by the shell of the housing 12. In this case, there is no need to set up an additional pipe separately, thereby reducing the number of parts in the product.

[0103] In any of the above embodiments, optionally, the water receiving tank 3 can be detachably installed inside the housing 12.

[0104] In this embodiment, when it is not necessary to add water to the food, the water receiving tank 3 and the water tank assembly 4 can be removed from the housing 12 to prevent the water receiving tank 3 from drying out. The water receiving tank 3 can also be made non-removable, in which case the water in the water tank assembly 4 can be poured out when it is not necessary to add water to the food.

[0105] 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 support 5, installed inside the cooking cavity 16, and a water tank 3 installed on the first support 5.

[0106] 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 receiving tank 3 is mounted on the first bracket 5, which makes the installation and removal of the water receiving tank 3 more convenient.

[0107] 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 the 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.

[0108] In this embodiment, the second bracket 6 can be used to support and install food carriers 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 tank 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 tank 3 to be achieved using the existing brackets within the housing 12, thereby simplifying the overall product structure and reducing the overall product cost.

[0109] Furthermore, the second bracket 6 is provided with multiple support parts 62, which are spaced apart along the height direction of the box 12. The two second brackets 6 can install the food carrier 10 at multiple height positions through the multiple support parts 62. This arrangement makes the installation height of the food carrier 10 adjustable, and also allows the two second brackets 6 to support and install multiple food carriers 10 at the same time.

[0110] In any of the above embodiments, optionally, as Figure 5 and Figure 6 As shown, a flange 32 is provided at the opening of the water receiving tank 3, and the flange 32 extends from the inside to the outside of the opening; the first bracket 5 includes a support bar 52, and the water receiving tank 3 is installed on the support bar 52 through the flange 32.

[0111] In this embodiment, the flange 32 enables the positioning and installation of the connecting water tank 3. To ensure the installation of the first bracket 5 with the connecting water tank 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 connecting water tank 3. To ensure the installation stability of the connecting water tank 3, the shape of the support bar 52 can be adapted to the outer wall of the connecting water tank 3, and the length of the support bar 52 can be set with reference to the outer periphery of the connecting water tank 3.

[0112] For example, when the water receiving trough 3 is elongated, the support strip 52 can cover three sides of the water receiving trough 3 to ensure the support stability of the support strip 52 for the water receiving trough 3. When the water receiving trough 3 is circular or near-circular, the support strip 52 can cover more than a quarter of the circumference of the water receiving trough 3.

[0113] In any of the above embodiments, optionally, as Figure 5 , Figure 6 and Figure 8 As shown, the water receiving trough 3 has a long and narrow structure, and it is arranged along the front and back direction of the housing 12. The long and narrow structure of the water receiving trough 3 can reduce the width occupied by the water receiving trough 3, thereby improving the space utilization of the cooking cavity 16.

[0114] Optionally, the water receiving trough 3 has a long strip structure, with support bars 52 supporting it on three surfaces. This ensures the installation stability of the water receiving trough 3.

[0115] In any of the above embodiments, optionally, the water tank assembly 4 is mounted on the housing 12. By mounting the water tank assembly 4 on the housing 12, the water tank assembly 4 and the housing 12 can form a whole, thereby facilitating the connection operation between the water tank assembly 4 and the connector 7. It also makes the entire unit more compact. Of course, in other solutions, the water tank can also be set independently of the housing 12.

[0116] Furthermore, such as Figure 1 As shown, the water tank assembly 4 is installed on the top of the tank body 12, so that the water tank assembly 4 is set higher, making it easier to use gravity to lower the water.

[0117] In any of the above embodiments, optionally, along the height direction of the tank 12, the water tank assembly 4 is located above the location of the water receiving trough 3, and the water in the water tank assembly 4 can flow into the water receiving trough 3 through the connector 7 under the action of gravity.

[0118] In this embodiment, the water tank assembly 4 is set relatively high, while the water receiving trough 3 is set relatively low. This allows the water in the water tank assembly 4 to fall under the action of gravity, thus making the water flow more smoothly. This reduces the dependence on water pumps and electrical control, thereby simplifying the product structure and reducing the product cost.

[0119] In this system, the water in the water tank assembly 4 flows into the water receiving tank 3 under the influence of gravity. That is, there is no power equipment between the water tank assembly 4 and the water receiving tank 3. The water in the water tank assembly 4 flows into the water receiving tank 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.

[0120] 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.

[0121] In any of the above embodiments, optionally, the water tank assembly 4 includes a water-containing cavity 42, a water outlet channel 44 communicating with the water-containing cavity 42, and a water inlet 46. Along the height direction of the tank body 12, the inner bottom wall of the water-containing cavity 42 gradually decreases from the water inlet 46 to the water outlet channel 44.

[0122] In this embodiment, water can be added to the water tank assembly 4 through the inlet 46, and the water in the water tank assembly 4 can be discharged through the outlet 44. The inner bottom wall of the water-containing cavity 42 gradually decreases from the inlet 46 to the outlet 44. This allows water to accumulate at the outlet of the water tank assembly 4 when there is little water in it, making it easier for the water in the water tank assembly 4 to flow out. This prevents water from remaining in the water tank assembly 4 and reduces the amount of residual water in the water tank assembly 4.

[0123] In any of the above embodiments, optionally, as Figure 1 , Figure 3 and Figure 4 As shown, the steam cooking appliance also includes: a mounting shell 9, which is mounted on the housing 12, and the mounting shell 9 is provided with a placement groove 92 for placing the water tank assembly 4; the mounting shell 9 is also provided with a water storage tank 94, and along the height direction of the housing 12, the bottom wall of the water storage tank 94 is lower than the bottom wall of the placement groove 92; when the water tank assembly 4 is installed in the placement groove 92, the water tank assembly 4 is connected to the water storage tank 94, and the water in the water tank assembly 4 can flow into the water storage tank 94; a connecting pipe 8 is installed on the mounting shell 9 and is connected to the water storage tank 94.

[0124] In this embodiment, the mounting housing 9 supports the water tank assembly 4. The mounting housing 9 comprises two parts: one part forms a placement groove 92 for supporting the water tank assembly 4, and the other part forms a water storage tank 94 for collecting water discharged from the water tank assembly 4. Water in the water storage tank 94 flows into the receiving tank 3 through the connecting pipe 8. With this structure, due to the mounting housing 9, the water tank assembly 4 does not need to be connected to the connecting pipe 8, etc. Therefore, no pipe connection is required during installation and disassembly of the water tank assembly 4, making it very convenient to remove the water tank assembly 4 for cleaning or adding water.

[0125] In any of the above embodiments, optionally, as Figure 3 and Figure 9 As shown, the water tank assembly 4 also includes: a water outlet channel 44; a valve assembly 48, installed at the water outlet channel 44 of the water tank assembly 4, capable of operating between a first position and a second position to open or close the water outlet channel 44; and a push rod 96 provided on the mounting housing 9, which is used to position the valve assembly 48 in the first position to open the water outlet channel 44 when the water tank assembly 4 is installed in the placement slot 92, and to position the valve assembly 48 in the second position and close the water outlet channel 44 after the water tank assembly 4 is removed from the placement slot 92.

[0126] 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 removed, the valve assembly 48 can automatically return to the second position to close the water outlet channel 44. This makes opening and closing the water tank assembly 4 very convenient. This structure allows the water tank assembly 4 to be opened and closed purely mechanically, without the need for electrical control, thus making the opening and closing structure of the water tank assembly 4 more durable.

[0127] like Figures 1 to 10As shown, an embodiment of the second aspect of this utility model provides a steam cooking appliance, including the water tank device provided in any embodiment of the first aspect.

[0128] 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.

[0129] In any of the above embodiments, optionally, as Figure 1 , Figure 8 and Figure 9 As shown, the steam cooking appliance includes a housing 12, which includes a cooking chamber 16. A cooking chamber inlet 122 and a mounting port 124 are provided at a first end of the housing 12 along a first direction, with the cooking chamber inlet 122 communicating with the cooking chamber 16. The steam cooking appliance also includes a door 14, installed at the first end of the housing 12 to open or close the cooking chamber inlet 122. A water tank assembly 4 can be pulled and installed onto the housing 12 via the mounting port 124 along the first direction. 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, with the water inlet 46 located at one end of the water tank shell 40 along the first direction; a cover 47, detachably installed on the water tank shell 40 to open or close the water inlet 46; and a sealing ring 49, located between the water tank shell 40 and the cover 47 to seal the gap between them.

[0130] In this embodiment, the steam cooking appliance includes a housing 12 and a door 14. A cooking chamber 16 is provided inside the housing 12, and the cooking chamber 16 communicates with a cooking chamber inlet 122. The door 14 is installed on the housing 12 and is used to open and close the cooking chamber inlet 122. A water tank assembly 4 is installed on the side of the housing 12 where the door 14 is located, for example, on the front side of the housing 12. The water tank assembly 4 can also be installed onto the housing 12 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 4 is also placed front-back on the housing 12, meaning it is installed horizontally on the housing 12, not vertically.

[0131] The box body 12 and the door body 14 constitute the outer shell structure of the entire product, forming a cooking box 1.

[0132] 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 the seal between the water tank shell 40 and the cover 47, a sealing ring 49 is also provided between the two. The sealing ring 49 can make the two seal the connection, thereby preventing water leakage from the water tank assembly 4.

[0133] In other oven designs, the water tank assembly typically has a water inlet directly on the side wall of the water tank shell without a removable cover. This makes it difficult to open the water tank and thus inconvenient for cleaning. In this application, a removable cover 47 is provided. This allows for easy cleaning of the water tank assembly 40 by opening the cover 47, improving the convenience of cleaning and ensuring cleanliness. Furthermore, this design allows users to easily inspect the interior of the water tank assembly 40 by opening the cover 47, facilitating timely detection of dirt and grime. This makes it easier for users to clean the water tank assembly 4 promptly and with greater peace of mind.

[0134] Specifically, the first direction can be the front-to-back direction of the tank 12. For example, the water tank assembly 4 can be disassembled and assembled from the front side of the tank 12. The cover 47 and the outer shell 40 of the water tank assembly 4 are also assembled along the front-to-back direction, which means that the water tank assembly 4 is installed horizontally on the tank 12, rather than vertically on the tank 12.

[0135] In any of the above embodiments, optionally, as Figure 8 As shown, the steam cooking appliance also includes: a heating device 2, installed on the housing 12, for heating the food in the cooking cavity 16; the water in the water tank 3 can be heated into steam by the heating device 2.

[0136] In this embodiment, the water tank 3 is used to store water, and the water in the water tank 3 can be heated into steam by the heating device 2 to humidify and replenish the food in the cooking cavity 16. With this configuration, the water tank 3 can be heated directly using the existing heating device 2 of the product, without the need for a separate heating structure, which simplifies the product structure. Of course, considering actual heating needs, a separate heating structure can also be provided for the water tank 3.

[0137] Optionally, such as Figure 8 As shown, the heating device 2 includes a heating element 22, which is installed on the top of the housing 12.

[0138] 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 tank 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 tank 3 into steam.

[0139] In any of the above embodiments, the steam cooking appliance may optionally include an oven. Of course, the steam cooking appliance may also be other devices that require a water tank.

[0140] Currently, steam ovens / steamers are generally equipped with a water tank assembly to supply water to the machine. The connection between the water tank assembly and the inner cavity is usually a straight pipe fitting located on the vertical surface of the cavity, leading the water from the water tank assembly to the corresponding device in the cavity. Placing the straight pipe fitting on the main vertical surface of the cavity significantly affects the effective volume of the cavity and the overall appearance of the inner cavity.

[0141] In this embodiment, a water receiving trough is provided in the inner liner cavity, and a metal connector is provided between the water tank assembly and the water receiving trough. The connector is located on the inclined surface on one side of the inner liner cavity, without occupying too much cavity volume. The connector is a kind of straight pipe fitting, so that the water can flow out stably and smoothly on the inclined surface of the inner liner to the corresponding device in the cavity, ensuring the smoothness of the water path.

[0142] In this embodiment, a metal connector is designed and installed on the inclined surface of one side of the inner tank. The connector is connected to the water tank assembly via a flexible hose. To prevent turbulence on the inclined wall when the water flow is weak, a straight or irregularly shaped pipe can be used to protrude from the inclined surface, serving to guide, collect, and block the water flow.

[0143] In this embodiment, the water outlet connector can stably connect the water tank assembly to the inner liner, ensuring stable water flow in the machine. There is no significant turbulence at the connector outlet, maintaining the cleanliness of the cavity. Alternatively, the connector can be replaced with a protrusion on the inclined surface of the cavity.

[0144] In the description of this specification, the terms "connection," "installation," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0145] In the description of this specification, the terms "one embodiment," "some embodiments," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention.
