[0001] This application claims priority to Chinese patent application CN202512007423.7, filed on December 26, 2025, entitled "Cooking Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of kitchen appliance technology, specifically providing a cooking device. Background Technology

[0003] With the diversification of kitchen appliances, cooking devices with steaming functions, such as steam ovens and steam-grill combos, have emerged on the market. The cooking principle of steaming is to provide high-temperature steam to the inner pot where the food is to be cooked. In an environment where steam permeates the inner pot, the food is cooked by adjusting parameters such as steam temperature, steam volume, and cooking time.

[0004] Taking a steam oven as an example, a typical steam oven structure includes a clean water tank and a waste water tank (located at the top of the steam oven between the main body and the inner liner). Both the clean water tank and the waste water tank can be removed from the steam oven in a removable manner, such as by pulling them out. For example, the clean water tank can be removed from the steam oven, water can be added to the outside of the steam oven, and then it can be reinstalled. Based on this, water is supplied to the steam generator through the clean water tank, the steam generator heats the water and converts it into high-temperature steam, and the steam is then directed to the inner liner, thus completing the supply of steam as a cooking medium.

[0005] However, since the clean water tank and wastewater tank are usually structurally and / or functionally independent structures, and their capacities are relatively fixed, there is still room for improvement in optimizing the integration of cooking equipment. Summary of the Invention

[0006] This application aims to solve, at least to some extent, the aforementioned technical problems and / or solve at least a portion of the aforementioned technical problems.

[0007] In view of this, this application provides a cooking device, comprising: a cooking body; a steam generator; a water transfer module, which is communicative with the steam generator and includes a module body, the module body forming a first water transfer zone and a second water transfer zone; and a pipeline assembly, comprising: a water inlet pipe, through which water from outside the cooking device can reach the first water transfer zone; and a drain pipe, through which water from the second water transfer zone can reach the outside of the cooking device; wherein the water transfer module is disposed on the back of the cooking device; wherein the module body includes a pressure relief port, which is integrated with the pressure relief ports corresponding to the first water transfer zone and the second water transfer zone.

[0008] This configuration enables the application of a water transfer module with integrated dual water transfer zones in cooking equipment, improving the overall integration of the equipment. Furthermore, the integrated pressure relief port simplifies the piping configuration of the cooking equipment while ensuring its sustainable operation.

[0009] Regarding the water inlet pipe, the water source outside the cooking equipment can be from a water purification device, a water pipe equipped with a water purification device, a fixed water source, etc. The exterior of the cooking equipment can also be a sewer, a wastewater collection container, or any scenario capable of absorbing wastewater (such as a ground-level site). Based on this, with the improvement of the dual water zones in the water transfer module, in this application, because the two water transfer zones within the module body can more flexibly switch between connected states with the outside, there is no need to reserve a large volume adapted to the usage. For example, the reliability of the cooking equipment can be ensured through multiple fixed water inlets and outlets, or by adding or removing water as needed based on parameters. This significantly reduces the space required for water-related aspects of the cooking equipment. On this basis, it is expected that the cooking equipment can be miniaturized, or that a larger volume can be reserved for the inner tank under the same conditions.

[0010] It is understood that those skilled in the art can determine the structural form of the main body of the module and the number of its components, the structural form / size / proportion / number of the first / second underwater transfer zones, and their relative positions, etc., according to actual needs. For example, the main body of the module can be a shell structure consisting of two parts that are fastened together (top and bottom / front and back), or a structure in which multiple parts are recombined between fastenings, etc., and the first / second underwater transfer zones can be arranged adjacently or spaced apart. For example, the first and second underwater transfer zones are roughly two interlocking horizontal U-shaped structures.

[0011] It is understood that those skilled in the art can determine the connection position / method between any pipeline and the water transfer module, the relative positions between multiple pipelines, and whether the pipelines are relatively independent or integrated, according to actual needs. For example, the connection position between the pipeline and the water transfer module can be set at any reasonable location, such as the top or side. Furthermore, it can be directly set on the original structure of the module body, or a structure (such as a recess or protrusion) can be machined into the module body, and the corresponding connection port or other connection structure can be set in that structure.

[0012] It is understood that those skilled in the art can determine the structural form of the pressure relief port and its location on the module body according to actual needs. For example, the pressure relief port can be located on the top or side of the module body. The pressure relief port can be a single integrated structure or a structure comprising multiple parts. For example, the pressure relief port includes a main channel and two branch channels extending from the main channel (integrated configuration), the two branch channels being connected to the first water transfer zone and the second water transfer zone, respectively.

[0013] In one possible implementation of the above-mentioned cooking equipment, the first water transfer zone and the second water transfer zone are connected to each other, and the pressure relief port is combined into one unit.

[0014] This configuration provides a possible implementation method for the integrated setting of pressure relief ports corresponding to the first and second water transfer zones.

[0015] It is understood that those skilled in the art can determine the manner in which the first water transfer zone and the second water transfer zone are connected to each other according to actual needs. For example, they can be connected to each other at a position higher than the highest permissible inlet water level of the first water transfer zone by means of a connecting structure such as a connecting hole. For example, a channel communicating with the second water transfer zone is provided above the first water transfer zone, and a connecting hole is provided at the top of the first water transfer zone.

[0016] In one possible implementation of the cooking device described above, the water transfer module is provided with an overflow structure, and the first water transfer zone and the second water transfer zone can be connected via the overflow structure.

[0017] This design ensures the reliability of the cooking equipment. For example, the overflow structure, while facilitating the combined pressure relief of the first and second water transfer zones, also prevents excessively high water levels in the first water transfer zone.

[0018] In one possible implementation of the above-mentioned cooking equipment, the overflow structure includes a climbing channel, the lower end of which is connected to the second water transfer zone, and the upper end of which is provided with an overflow port connected to the first water transfer zone.

[0019] This configuration provides a possible structural form for the overflow structure.

[0020] In this way, when it is necessary to depressurize the gas in the second water transfer zone, considering that the cleanliness of the water in the second water transfer zone cannot be guaranteed, the gas may contain certain impurities and odors. As the gas rises in the climbing channel, the impurities in the gas will adhere to the wall of the climbing channel as much as possible, and the degree of odor will be reduced to a certain extent. Therefore, it effectively prevents the second water transfer zone from affecting the first water transfer zone due to the integration of the depressurization function.

[0021] In one possible implementation of the above-mentioned cooking device, the pressure relief port is located at the upper end of the module body corresponding to the climbing channel; or it is located above the module body corresponding to the first water transfer zone.

[0022] This configuration provides a possible structural form for the pressure relief port.

[0023] In one possible implementation of the above-mentioned cooking device, the pressure relief port includes an integrated first pressure relief part and a second pressure relief part. The first pressure relief part is connected to the first water transfer zone, and the second pressure relief part is connected to the second water transfer zone. The first pressure relief part and the second pressure relief part are either connected to each other or independent of each other.

[0024] This configuration presents another possible implementation method for integrating the pressure relief ports corresponding to the first and second water transfer zones. Specifically, pressure relief for the water transfer module is achieved by physically integrating the first and second pressure relief components.

[0025] It is understood that those skilled in the art can determine the structural form, formation method, and integration / connection method of the first / second pressure relief section according to actual needs. For example, the first pressure relief section may be an interface (pipe segment), and the inlet side of the second pressure relief section may be axially fitted inside the interface, while the outlet side may radially protrude from the wall of the interface. Alternatively, the downstream side of the first pressure relief section may be directly connected to the external environment, while the downstream side of the second pressure relief section may be connected to the first pressure relief section.

[0026] In one possible implementation of the above-mentioned cooking device, the pressure relief port is provided with a partition structure, which divides the pressure relief port into a first pressure relief portion and a second pressure relief portion that are independent of each other.

[0027] This configuration provides possible ways to form the first / second pressure relief section, such as the partition structure being any reasonable structural form, such as a plate structure, a cylindrical structure, or a corrugated structure.

[0028] In one possible implementation of the above-mentioned cooking device, the top of the module body forms a stepped surface, and the pressure relief port is located on the high side of the stepped surface; and / or the cooking device includes a water level detection component, which is located in the first water transfer zone at a position corresponding to the low side of the stepped surface.

[0029] This design allows for an increase in the integration of cooking equipment.

[0030] The water level detection component (such as an electronic float) is mainly used to detect the water level in the first water transfer zone. The overflow outlet prevents overflow by closing the inlet in case the first water level detection component malfunctions. Furthermore, a flow-limiting component (not shown) can be installed at a location corresponding to the inlet valve or at a suitable location on the inlet pipe to determine whether to stop the water intake based on the water flow, thus ensuring the reliability of the steam oven. If there is no overflow outlet, a water level detection component such as a mechanical float can be added as a safety measure.

[0031] In one possible implementation of the above-mentioned cooking equipment, the piping assembly includes a pressure relief pipe, the pressure relief port being connected to the heat dissipation duct of the cooking equipment via the pressure relief pipe; and / or the second water transfer zone includes a first portion and a second portion arranged in a horizontal direction, at least a portion of the second portion protruding out of the first water transfer zone in a direction.

[0032] This configuration provides a possible structural form for the second water transfer zone.

[0033] Specifically, while reserving sufficient space for the first water transfer zone, the second section allows for an appropriate increase in the volume of the second water transfer zone. Furthermore, it provides more installation space in the corresponding location for structures such as water level sensors and inner tank residual water recovery pipes. Moreover, since it is located only at the bottom, it does not interfere with the installation of structures related to the first water transfer zone, such as inlet valves.

[0034] It is understood that those skilled in the art can determine the structural form and connection method of the first and second parts according to actual needs. For example, the connection area between the two parts can be maximized to achieve complete connection, the connection position can be reduced in diameter (e.g., a partition can be provided with a connecting hole or other connection structure), or a filtering / guiding structure can be provided between the two parts (e.g., the bottom of the second part is a slope).

[0035] In one possible implementation of the above-mentioned cooking device, the main body of the module is provided with a first guide structure at the bottom position corresponding to the first water transfer zone; and / or the main body of the module is provided with a second guide structure at the top position corresponding to the first part; and / or the main body of the module is provided with a third guide structure at the bottom position corresponding to the second water transfer zone.

[0036] The first guiding structure prevents impurities from lingering in the first water transfer zone, which requires high cleanliness and is difficult to clean. The first guiding structure can be a slope, an arc, or other structure that creates a height difference at the starting end. For example, at the lower end of the first guiding structure, a first steam generator pipe is configured to connect to the inlet of a steam generator. The second guiding structure allows gas requiring depressurization to rise more smoothly to the aforementioned depressurization port. The third guiding structure allows water in the second transfer zone to accumulate better. The second / third guiding structures can have the same or different structural forms from the first guiding structure, and the second and first guiding structures can be independently configured or at least integrated to some extent. For example, the first guiding structure is a slope formed on the upper support plate, and the second guiding structure is an arc formed on the lower support plate, with connecting ribs between the two support plates.

[0059] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment is described in conjunction with a steam oven / grill combo and an external water purifier connected to the water inlet pipe, it is clear that those skilled in the art can flexibly adjust the type of cooking equipment, the water source connected to the water inlet pipe, etc. For instance, the cooking equipment could also be any device containing a steaming function, such as a steam oven, a steam oven / grill combo, or any other device.

[0060] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0062] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can still be implemented without certain specific details. In some examples, the structure and principles of steam ovens well-known to those skilled in the art are not described in detail, in order to highlight the main points of this application.

[0063] The following will refer to Figures 1 to 6 This application is to be described in at least a portion thereof.

[0064] Example 1

[0065] Reference Figures 1 to 3In one possible implementation, the steam oven mainly includes a cooking body, which comprises a cabinet 1 and an inner liner 2 disposed within the cabinet. The inner liner forms a cooking chamber capable of holding the food to be cooked. For example, the inner liner may have a shelf, on which the food to be cooked can be placed directly or placed on a dish (such as a plate) placed on the shelf. The structures related to the steaming function of the steam oven mainly include a steam generator 3, a water transfer module 4, and a piping assembly 5. The steam generator is mainly used to generate steam as a cooking medium and send the steam into the cooking chamber. The water transfer module 4 includes a module body 41, which forms a first water transfer zone 411 and a second water transfer zone 412. The first water transfer zone is mainly used to collect clean water and distribute it to the steam generator; therefore, the first water transfer zone can be called the clean water zone. The second water transfer zone is mainly used to collect wastewater and discharge it in a timely manner; therefore, the second water transfer zone can be called the wastewater zone. In this application, the water transfer module 4 is located on the back of the inner tank, connecting the clean water area and the water purification equipment, as well as the wastewater area and the outside (such as the drain pipe). This ensures the continuous and reliable operation of the steam oven without the need for manual water addition or pouring.

[0066] In this example, steam generator 3 is a steam generator installed at the top of the inner liner. Obviously, the structure, type, and location of the steam generator can be flexibly adjusted according to actual needs. For example, the steam generator can also be an evaporation plate, multiple steam generators can be included, and the steam generator can be installed at the top / back / bottom of the inner liner.

[0067] In this example, the main body 41 of the module is roughly a box structure, and the second water transfer zone 412 is located below the first water transfer zone 411. The height of the first water transfer zone is greater than that of the second water transfer zone, and therefore its volume is also significantly larger. For example, the height of the first water transfer zone is 3-5 times that of the second water transfer zone. This allows the larger first water transfer zone to hold more clean water, thus reducing the frequency of water intake, while the smaller second water transfer zone, which cannot store large amounts of wastewater, allows wastewater to be discharged promptly.

[0068] In one possible implementation, the second water transfer zone 412 includes a first portion 4121 on the left and a second portion 4122 on the right, wherein the second portion extends horizontally (relative to the right side of the module body), thereby appropriately increasing the volume of the second water transfer zone and reserving more installation space at the location corresponding to the second portion to configure the corresponding structure.

[0069] In one possible implementation, the interior of the module body 41 is divided into the aforementioned first water transfer zone and second transfer zone via a first partition structure 413. In this example, the first partition structure is a partition plate, and the structure corresponding to the first partition structure is the first part of the second transfer zone. Obviously, those skilled in the art can flexibly select the structural form of the first partition structure according to actual needs, and flexibly adjust the coverage of the first partition structure according to the specific configuration of the second transfer zone. For example, the first partition structure can also be a combination of multiple structures, and the first partition structure can also cover a part of the second part.

[0070] In one possible implementation, a first guide structure 4141 is provided at the top of the first partition structure 413. The first guide structure 4142 is mainly used to guide impurities in the water to the position near the left side where water is supplied to the steam generator, so as to avoid impurities from remaining at the bottom of the first water transfer zone, which has high cleanliness requirements and is difficult to clean, for a long time. A second guide structure is provided at the bottom of the first partition structure to allow gas to flow more smoothly to the climbing channel connected to the pressure relief port. In this example, the first / second guide structures are located on the slopes on both sides of the partition plate.

[0071] In one possible implementation, a third guide structure 4143 is provided inside the box at the position corresponding to the bottom of the second water transfer zone. The third guide structure is mainly used to converge water in the relatively narrow wastewater zone to the left side. In this example, the bottom of the first part and the second part is roughly a convergence structure composed of three planes, with the two sides concave towards the middle and the right side sloping downwards to the left. The top height of the second part is greater than that of the first part. The first part and the second part are completely connected (the connected area is the full area of ​​the right side of the first part). The extension length of the second part is less than the width of the box (e.g., 1 / 3 to 1 / 2 of the width of the box).

[0072] Clearly, the structural form of the third guiding structure can be flexibly adjusted according to actual needs, such as a plane or curved surface sloping downwards from right to left. Furthermore, those skilled in the art can determine the structural form, size, and connection method between the first and second parts according to actual needs. For example, a stepped surface can be formed between the bottom of the second part and the bottom of the first part.

[0073] In the case where clean water enters the first water transfer zone 411 and wastewater / residual water enters the second water transfer zone 412, the internal pressure of the first / second water transfer zone may increase, potentially hindering the corresponding water circulation. Therefore, a pressure relief port 421 is provided on the module body 41 to balance the air pressure inside the module body, thereby ensuring the operational reliability of the steam oven. In this application, the pressure relief ports corresponding to the first and second water transfer zones are centrally located. For example, in this example, the pressure relief port is located at the top near the right side. Obviously, the location of the pressure relief port can be flexibly adjusted according to actual needs. For example, if the overflow port is on the left, the pressure relief port can also be located on the left side.

[0074] Main reference Figure 3 In one possible implementation, the casing also includes an overflow structure 422, through which the first water transfer zone can communicate with the second water transfer zone. This allows excess water in the first water transfer zone to overflow into the second water transfer zone in a timely manner, ensuring the reliability of the steam oven. Furthermore, due to the overflow structure, gas from the second water transfer zone can reach the first water transfer zone through the overflow structure, thus enabling the pressure relief ports of both water transfer zones to be shared.

[0075] In this example, the overflow structure 422 includes an overflow port 4221. In this application, the overflow structure also includes a climbing channel 4222 extending generally vertically (e.g., it can be inclined, arc-shaped, spiral, or otherwise upward-trending). If the channel is narrow (with a small cross-sectional size, such as no more than 1 / 4 of the cross-sectional size of the first water transfer zone, exemplarily 1 / 10-1 / 5), the overflow port is located near the top of the climbing channel 4222. In this way, when a pressure relief port is needed to depressurize the gas in the second water transfer zone, considering that the cleanliness of the water in the second water transfer zone cannot be guaranteed, the gas may contain certain impurities and odors. As the gas rises within the climbing channel, the impurities will adhere to the wall of the climbing channel as much as possible, and the odor will be reduced to some extent. Therefore, the influence of the second water transfer zone on the first water transfer zone due to the integration of the pressure relief function is effectively prevented. In this example, the inner wall of the climbing channel 4222 and the upper first baffle form the overflow port. Furthermore, a second baffle parallel to the climbing channel is provided on the inner side of the overflow outlet to prevent odors from the second water transfer zone from entering the first water transfer zone as much as possible. Obviously, those skilled in the art can use any reasonable structural form to create the overflow outlet.

[0076] In this example, the overflow port 4221 is located on the right side of the water transfer module, and the pressure relief port 421 is located on the right side and above the climbing channel 4222. Therefore, when pressure relief is needed in the first water transfer zone, the gas pressure relief path is: first water transfer zone - overflow port - pressure relief port. When pressure relief is needed in the second water transfer zone, the gas pressure relief path is: second water transfer zone - climbing channel - pressure relief port.

[0077] In one possible implementation, the piping assembly 5 mainly includes a first piping assembly connecting the water transfer module 4 to the steam generator 3 and a second piping assembly connecting the water transfer module 4 to the outside. The first piping assembly includes a first steam generator pipe 51 and a second steam generator pipe 52. The first water transfer zone can be connected to the inlet of the steam generator (the inlet pipe of the steam generator) via the first steam generator pipe, and the outlet of the steam generator can be connected to the second water transfer zone (the waste water recovery pipe of the steam generator) via the second steam generator pipe. The second piping assembly mainly includes an inlet pipe 53 and a drain pipe 54. Water from an external water purification device of the steam oven can reach the first water transfer zone via the inlet pipe; water in the second water transfer zone can reach the external drain pipe of the steam oven via the drain pipe.

[0078] In one possible implementation, the piping assembly further includes a third piping assembly related to descaling. This third piping assembly mainly includes a descaling medium extraction pipeline 55, a descaling medium dispensing pipeline, and a descaling residual liquid recovery pipeline. In this example, the descaling medium is citric acid. The steam oven has a designated location for adding citric acid (e.g., near the front top). After preparing the citric acid, the user can add it to the steam oven through this location. Under the action of the descaling pump 64, the citric acid is extracted into the clean water transfer zone. In this example, after citric acid enters the clean water zone, the descaling medium dispensing pipeline is shared with the aforementioned first steam generator pipeline, and the descaling residual liquid recovery pipeline is shared with the aforementioned second steam generator pipeline. In this way, under the action of the water pump 63, the mixed liquid (containing clean water and descaling medium) in the first water transfer zone is dispensed to the steam generator through the first steam generator pipeline. After descaling is completed (e.g., after heating to a certain temperature (e.g., 80°C) and soaking for a certain time (e.g., 45 min)), under the action of the drain pump 62, the generated waste liquid is recovered to the wastewater transfer zone through the second steam generator pipeline or discharged to the outside of the steam oven.

[0079] In one possible implementation, the piping assembly further includes a pressure relief pipe 56 associated with the pressure relief of the water transfer module. For example, a heat dissipation assembly is typically installed on the top of a steam oven, which mainly includes a cooling fan and a cooling duct. Under the action of the cooling fan, gas flows through the cooling duct and is discharged to the outside of the steam oven, thus dissipating heat from the top area. The pressure relief pipe is connected to the cooling duct.

[0080] In one possible implementation, the piping assembly also includes an inner pot wastewater recovery pipe 57 related to liquid recovery within the cooking chamber. One end of the inner pot wastewater recovery pipe is connected to or near the bottom of the inner pot, and the other end is connected to a wastewater area. This allows for timely recovery of liquid from the bottom of the inner pot during cooking. If the inner pot has a self-cleaning function, it can also be used to form a self-cleaning circulation loop (bottom of inner pot - inner pot wastewater recovery pipe - wastewater area - cleaning assembly - bottom of inner pot).

[0081] Corresponding to the piping assembly, the steam oven also includes a pump assembly to ensure that the liquid within the piping can flow under power guidance. In one possible implementation, the pump assembly includes an inlet pump 61 for delivering clean water from an external water purification device to the first water transfer zone, a drain pump 62 for discharging water from the wastewater zone, a supply pump 63 for delivering clean water from the clean water zone to the steam generator, and a descaling pump 64 for extracting descaling media. In this example, the inlet pump 61 is positioned approximately horizontally on the right side of the module body, the drain pump 62 is positioned approximately horizontally at the bottom left side of the housing (in this example, the first part of the housing extends a certain length along the left side to facilitate the installation of the drain pump), the supply pump 63 is positioned approximately vertically on the left side of the module body, and the descaling pump 64 is positioned approximately horizontally at the top of the housing. In this example, the right side of the top of the housing is higher than the left side, thus forming a stepped surface, and the descaling pump is installed on the left side. Obviously, where reasonably feasible, those skilled in the art can flexibly adjust the type and position of each pump in the pump assembly according to actual needs.

[0082] In one possible implementation, a water level detection component 7, such as an electronic float, is provided inside the housing on the left side corresponding to the aforementioned stepped surface. Furthermore, a water level detection component, such as a water level sensor, is also provided at a location corresponding to the second water transfer zone; exemplarily, the water level sensor is located near the right side of the second section. In this way, by creating the stepped surface, a mounting position for the descaling pump is constructed on the outside of the housing, while a low position required for the water level detection component is constructed on the inside of the housing, thereby improving the compactness of the module body.

[0083] In this example, the cooking device is a steam oven, therefore it also includes structures related to the baking function. The baking function works by providing circulating hot airflow to the cooking chamber containing the food, thus cooking it using hot air baking. Cooking can be done solely with hot airflow, but steam can also be introduced (e.g., in the tender baking mode). Correspondingly, the structures of the steam oven for the baking function typically include a temperature-regulating fan (which guides the airflow to form a hot air stream), hot air heating components (such as heating coils, primarily used to heat the air near the temperature-regulating fan), and a fan shroud assembly (forming a hot air chamber that houses the fan and heating coils, and has air inlets and outlets that connect to the cooking chamber to form a circulating airflow). Clearly, the specific structural forms of these components and how they constitute the steam oven can be flexibly adjusted according to actual needs.

[0084] In addition, heating elements such as heating tubes are installed at the top, sides, and bottom of the inner pot so that the temperature of the cooking medium (hot air and / or steam) in the cooking chamber can be adjusted when needed.

[0085] As can be seen, in the preferred embodiment of this application, by integrating the dual-function water transfer zone into the water transfer module located on the back of the inner tank, the integration of the cooking equipment is significantly improved, thus freeing up space in the top clear water / waste water box. This can reduce the overall height of the machine or increase the volume of the inner tank while maintaining the same height. Furthermore, the integration is further improved by configuring the piping components, pump, and detection components on the main body of the module.

[0086] Example 2

[0087] Main reference Figure 4 In this embodiment, the overflow structure 422 also includes an overflow port 4211 and a climbing channel 4222. However, in this embodiment, the climbing channel 4222 is located on the left side of the water transfer module, and the pressure relief port 421 is located on the high side of the stepped surface near the left side. In this example, the downward protruding structure and the upward-opening recessed structure form the overflow port. Compared with Embodiment 1, the overflow port and the pressure relief port are located relatively far apart, and this structure can better prevent the taste from the second water transfer zone from entering the first water transfer zone.

[0088] Other structures are similar to those in Embodiment 1, and will not be described again here.

[0089] Example 3

[0090] Main reference Figure 5 and Figure 6In this embodiment, the pressure relief port 421 includes a first pressure relief portion 4211 and a second pressure relief portion 4222. In this example, the pressure relief port 421 is approximately an interface, within which a second partition structure 4213 is provided, thereby dividing the pressure relief port into the first pressure relief portion 4211 and the second pressure relief portion 4222. In this example, the second partition structure is approximately a plate-like structure arranged along the axial direction of the interface. Therefore, the cross-sections of the first pressure relief portion 4211 and the second pressure relief portion 4222 are combined to form a circle, and their cross-sectional ratio can be flexibly adjusted according to actual needs. The first pressure relief portion 4211 is connected to the first water transfer zone 411, and the second pressure relief portion 4222 is connected to the second water transfer zone 412.

[0091] In this embodiment, since the second pressure relief section 4212 can relieve pressure on the second water transfer zone, there is no need to provide an overflow port. However, to ensure the feasibility of the pressure relief path, the climbing channel 4222 in embodiment 1 is retained. As in this example, the climbing channel is located on the right side of the module body 41, and the pressure relief port is located on the top of the module body with a larger cross-sectional dimension than that in embodiment 1. Part of the cross-section falls into the position communicating with the first water transfer zone, and another part of the cross-section falls into the position communicating with the climbing channel.

[0092] In this embodiment, since there is no overflow outlet, a mechanical float, primarily used to prevent overflow (as a safety feature, with a small number activated), can be installed in the first water transfer zone. The detection position of the electronic float and the trigger position of the mechanical float have a height difference. Those skilled in the art can determine this height difference based on actual needs to ensure the reliability of the steam oven through the combination of the two detection components. Furthermore, a flow-limiting component (not shown) can be configured at a location corresponding to the water inlet valve or at a suitable location in the water inlet pipe. This flow-limiting component primarily reduces the probability of the mechanical float being triggered by limiting the flow rate. Compared to not having a flow-limiting component, the height difference between the detection position of the electronic float and the trigger position of the mechanical float can be reduced. This is because the flow-limiting component acts as an "ally" of the electronic float, ensuring the reliability of the water volume in the clear water zone through their cooperation, and also acts as a "gatekeeper" for the mechanical float, reducing the probability of it being triggered. Clearly, those skilled in the art can determine the structure and location of the water level detection component and the flow-limiting component based on actual needs.

[0093] Other structures are similar to those in Embodiment 1, and will not be described again here.

[0094] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
