[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0050] This embodiment provides a cooking device with a steam cooking function, which can condense and dissipate heat from the hot steam in the cooking chamber during or after cooking, thereby reducing the steam emission temperature and steam emission volume and improving the user experience of the cooking device.

[0051] like Figs. 1 to 4 As shown, the cooking equipment includes a body, a steam module, and a control module. The body includes an inner pot assembly 200, a casing surrounding the inner pot assembly 200, and a base 300 mounted on the bottom of the inner pot assembly 200. The inner pot assembly 200 has a cooking cavity with an open front side. The steam module is installed between the inner pot assembly 200 and the casing to provide hot steam to the inside of the cooking cavity to meet the needs of steaming and cooking food. The control module is communicatively connected to the steam module to control its operation.

[0052] To achieve steam condensation and cooling, in this embodiment, the cooking equipment further includes a steam condensation device 100, which includes a fan cover 1, a duct base plate 4, a fan assembly 3, and a condensation assembly 2. The fan cover 1 is installed on the duct base plate 4 and forms an inner cavity with the duct base plate 4. The fan cover 1 has an air inlet 1111 and an air outlet 114 that are in fluid communication with the inner cavity. The fan assembly 3 includes a drive motor 31 installed on the fan cover 1 and an impeller 32 installed in the inner cavity. The impeller 32 guides the external cooling airflow to flow sequentially through the air inlet 1111, the inner cavity, and the air outlet 114. The condensation assembly 2 is installed at the air outlet 114 and has a condensation channel inside, which is used to introduce steam.

[0053] When steam needs to be released, the steam in the cooking chamber enters the condensation channel, and at the same time, the impeller 32 starts to run, so that the cooling airflow is blown sequentially through the air inlet 1111, the inner cavity and the air outlet 114 to the condensation component 2, cooling the condensation component 2, thereby cooling the hot steam in the condensation channel.

[0054] The fan cover 1 includes a housing 11, which has an inner cavity for rotatably accommodating the impeller 32 and an air inlet 1111 and an air outlet 114 in fluid communication with the inner cavity. The housing 11 includes an end plate 111 and a side plate 112. The side plate 112 is arranged around the end plate 111 to define the inner cavity. The housing 11 has an installation opening on the opposite side of the end plate 111 for assembling the fan cover 1 onto a cooking device. The air inlet 1111 is opened on the end plate 111. The side plate 112 has a first end and a second end arranged at intervals in the circumferential direction, and the air outlet 114 is formed between the first end and the second end. A first positioning structure is provided at the end of the end plate 111 near the air outlet 114, and the first positioning structure positions the condenser assembly 2.

[0055] The open end face of the installation is fitted to the bottom plate 4 of the air duct so that the fan cover 1 and the bottom plate 4 of the air duct are enclosed to form an inner cavity. The condenser assembly 2 is provided with a second positioning structure, which is positioned and cooperates with the first positioning structure.

[0056] The fan cover 1 provided by this utility model forms an inner cavity and an air outlet 114 by means of an end plate 111 and a side plate 112, which simplifies the structure of the fan cover 1 and reduces its cost. By setting an air inlet 1111 on the end plate 111 and forming an air outlet 114 between the two ends of the side plate 112, the air inlet direction and the air outlet direction are approximately perpendicular, forming the impeller 32 to discharge air laterally, which is conducive to guiding the airflow. By setting a first positioning structure at the end of the end plate 111 near the air outlet 114, it is convenient to realize the installation and positioning of the fan cover 1 and the condenser assembly 2, better ensuring the assembly accuracy of the two, thereby guiding the airflow to the condenser assembly 2, improving the condensation and heat dissipation effect of the condenser assembly 2, and improving the utilization effect of the cooling airflow.

[0057] The steam condensing device 100 provided by this utility model, by adopting the aforementioned fan cover 1 and setting the condensing component 2 at the air outlet 114, can better promote the flow of cooling air guided by the impeller 32 to the condensing component 2; at the same time, the condensing component 2 and the fan cover 1 are installed and positioned by the first positioning structure and the second positioning structure, which can further ensure the relative positional accuracy of the fan cover 1 and the condensing component 2, ensure the accurate and reliable installation of the condensing component 2 at the air outlet 114, and improve assembly efficiency; furthermore, the condensing component 2 is set on one side of the fan cover 1, which can improve the overall structural compactness of the steam condensing device 100 and reduce the footprint of the steam condensing device 100.

[0058] The cooking equipment provided by this utility model, by adopting the above-mentioned steam condensation device 100, can improve the effect of steam condensation and improve the structural compactness of the cooking equipment.

[0059] For ease of description, the direction perpendicular to the end plate 111 is defined as the first direction, that is, the rotation axis of the impeller 32 is set along the first direction, the first end and the second end are spaced apart in the second direction, the second direction is perpendicular to the first direction, and the direction perpendicular to both the first and second directions is defined as the third direction.

[0060] In this embodiment, the first direction is the front-to-back direction, the second direction is the up-and-down direction, and the third direction is the left-to-right direction. That is, steam condensation is directed to the rear side of the inner liner assembly 200, resulting in a highly compact overall structure for the cooking device and reducing its size in the left-to-right direction. In other embodiments, the first direction may also be the left-to-right direction.

[0061] To improve the ease of installation of the steam condenser 100 on the inner liner assembly 200, the inner liner assembly 200 includes an inner liner body 201 and an inner liner outer cover 202 disposed on one side of the inner liner body 201. The inner liner body 201 has a cooking cavity open on one side, and the steam condenser 100 is installed on the side of the inner liner outer cover 202 away from the inner liner body 201. Both the inner liner body 201 and the inner liner outer cover 202 have steam holes that communicate with each other, allowing steam inside the inner liner body 201 to enter the condensation channel through the steam holes.

[0062] For example, the duct bottom plate 4 includes a bottom plate portion 41 and a surrounding edge portion 42 surrounding the bottom plate portion 41. The edge of the surrounding edge portion 42 is folded outward to form a fixed edge portion 43. The fixed edge portion 43 is attached to and detachably connected to the inner liner outer cover 202. The duct bottom plate 4 and the inner liner outer cover 202 are spaced apart to form a cavity between them. The cavity is used to reduce the conduction of heat in the cooking cavity to the fan assembly 3 and the condenser assembly 2, thereby improving the condensation and cooling effect of steam.

[0063] It is worth noting that the specific structure of the inner liner assembly 200 and the specific mating structure between the air duct base plate 4 and the inner liner assembly 200 can be set with reference to the existing technology. This is not the focus of this utility model and will not be elaborated here.

[0064] In this embodiment, the cross-sectional area of ​​the inner cavity gradually decreases along the direction away from the air outlet 114. This allows for maintaining the size of the air outlet 114 in the second direction while reducing the size of the end of the housing 11 away from the air outlet 114, thus reducing the footprint of the fan shroud 1. Simultaneously, this arrangement reduces the airflow velocity towards the air outlet 114, thereby increasing the heat exchange effect between the cooling airflow and the condenser assembly 2 at the air outlet 114, improving the condensation effect. Furthermore, this arrangement increases the airflow volume of the cooling airflow when the impeller 32 rotates. Specifically, the width of the inner cavity in the second direction gradually increases along the direction away from the air outlet 114, that is, the width of the end plate 111 gradually decreases along the direction away from the air outlet 114.

[0065] The edge of the end plate 111 includes two opposing and spaced-apart side edges, an arc edge connecting one corresponding end of the two side edges, and an air outlet edge connecting the other end of the two side edges. The arc opening of the arc edge faces the air outlet edge, and the arc edge is smoothly connected to the side edges. Side plates 112 are connected between the arc edge and the two side edges, and the air outlet edge forms the edge of the air outlet 114. This arrangement facilitates the placement of the side plates 112 and the formation of the air outlet 114; simultaneously, the arc edge helps guide airflow towards the air outlet 114 and reduces the overall size of the fan cover 1.

[0066] Furthermore, the center of the arc edge is located on the rotation axis of the impeller 32, which makes the distance between the arc edge and the air outlet 114 equal everywhere, which helps to improve the structural compactness and reduce the overall footprint of the fan cover 1.

[0067] In this embodiment, the distance between the two side edges gradually increases in the direction towards the air outlet edge, so that the fan cover 1 is flared in the direction towards the air outlet 114. Furthermore, the included angle between the two side edges is greater than 0° and less than 45°.

[0068] To improve the ease of installation of the fan cover 1 on the duct base plate 4, the fan cover 1 also includes a connecting edge 113 connected to the end of the side plate 112 away from the end plate 111. The connecting edge 113 fits and connects to the duct base plate 4. The connecting edge 113 is preferably located on the outer side of the inner cavity and is detachably connected to the duct base plate 4 to improve the ease of assembly and disassembly of the fan cover 1.

[0069] To improve the ease of installation of the drive motor 31 on the fan cover 1, the fan cover 1 also includes a motor mounting part 12 located at the air inlet 1111. The motor mounting part 12 has a mounting through hole 123 that communicates directly with the air inlet 1111, and a ventilation opening communicating with the air inlet 1111 is provided on the outside of the mounting through hole 123. The motor housing of the drive motor 31 passes through the mounting through hole 123. This arrangement facilitates the installation of the drive motor 31 on the fan cover 1, and the ventilation opening prevents the installation of the drive motor 31 from affecting the air intake of the inner cavity.

[0070] Furthermore, the motor mounting part 12 includes a mounting ring 121, which is spaced apart on the side of the end plate 111 away from the side plate 112 and coaxially arranged with the air inlet 1111. The mounting ring 121 is connected to the end plate 111 via connecting arms 122. Multiple connecting arms 122 are spaced apart along the circumference of the mounting ring 121, and a ventilation opening is formed between two adjacent connecting arms 122. The inner hole of the mounting ring 121 forms a mounting through hole 123. By spaced apart between the mounting ring 121 and the end plate 111, the depth of the motor housing extending into the inner cavity can be reduced, thereby reducing the space occupied by the drive motor 31 in the inner cavity. This allows for the installation of the impeller 32 while reducing the axial dimension of the fan cover 1 on the output shaft. At the same time, this arrangement also facilitates the heat dissipation of the drive motor 31.

[0071] Furthermore, the connecting arm 122 includes a first arm and a second arm that are vertically connected. The first arm extends radially along the mounting ring 121, and the second arm extends axially along the mounting ring 121 and is connected to the end plate 111. The motor mounting part 12 is preferably integrally formed with the end plate 111, but it can also be welded together.

[0072] In this embodiment, a mounting ear extends radially outward from the end of the motor housing away from the impeller 32. Multiple mounting ears are spaced circumferentially along the motor housing. The mounting ears are detachably connected to the fan cover 1, thereby facilitating the installation of the drive motor 31. Specifically, the mounting ear is connected to the mounting ring 121 or to the connection between the mounting ring 121 and the first arm.

[0073] The condenser assembly 2 includes a radiator 21 and a condenser tube 22. The radiator 21 includes a first mounting plate 211 and a second mounting plate 212 arranged opposite to each other and spaced apart. Multiple heat dissipation fins 213 are spaced apart between the first mounting plate 211 and the second mounting plate 212, and a ventilation channel is formed between two adjacent heat dissipation fins 213. The ventilation channel is directly connected to the air outlet 114. A second positioning structure is provided on the first mounting plate 211, and the second mounting plate 212 is connected to the air duct base plate 4. The condenser tube 22 includes multiple condensation sections connected in sequence by bends. Each condensation section passes through all the heat dissipation fins 213, and a condensation channel is formed in the inner cavity of the condenser tube 22. This type of condenser assembly 2 has a simple structure and good heat dissipation effect, and it is also conducive to the cooperation between the condenser assembly 2 and the fan cover 1. At the same time, the arrangement of this type of condenser assembly 2 helps to reduce the footprint of the steam condensation device 100 in the first direction and improves the structural compactness.

[0074] The first positioning structure includes a positioning groove 1112 recessed towards the inner cavity to improve the positioning effect and reduce the processing difficulty of the first positioning structure. The positioning groove 1112 is formed by stamping the end plate 111. The first mounting plate 211 has a positioning edge 2112 extending from the heat dissipation fins 213 towards the fan cover 1. The positioning edge 2112 is accommodated in the bottom of the positioning groove 1112, thereby enabling the radiator 21 to be installed and positioned on the fan cover 1 through the cooperation of the positioning edge 2112 and the positioning groove 1112. At the same time, this arrangement also avoids the first mounting plate 211 protruding from the surface of the end plate 111, thereby improving the overall aesthetics of the steam condensing device 100.

[0075] In other embodiments, one of the first positioning structure and the second positioning structure may have a protruding positioning protrusion, and the other may have a positioning hole, with the positioning protrusion inserted into the positioning hole.

[0076] The first mounting plate 211 has a main board portion 2111 disposed opposite to the heat sink fins 213, and a positioning edge portion 2112 disposed on one side of the main board portion 2111, wherein the length of the positioning edge portion 2112 is less than the length of the main board portion 2111. This facilitates the engagement of the positioning edge portion 2112 with the positioning groove 1112 while increasing the length of the main board portion 2111, making the length of the main board portion 2111 more compatible with the length of the air outlet 114.

[0077] The positioning edge 2112 has a trapezoidal structure with the short side of the trapezoidal structure facing the fan cover 1, that is, the long side of the trapezoidal structure is connected to the main board part 2111, so as to facilitate the insertion of the positioning edge 2112 in the positioning groove 1112 and avoid interference between the positioning edge 2112 and the fan cover 1.

[0078] Furthermore, the length of the motherboard portion 2111 along the second direction is approximately equal to the length of the heat sink fins 213 along the second direction. The width of the motherboard portion 2111 along the third direction is approximately equal to the width of the heat sink fins 213 along the third direction. The projections of the heat sink fins 213 onto the motherboard portion 2111 are all located inside the motherboard portion 2111.

[0079] In this embodiment, the main board 2111 abuts against the side of the fan cover 1 near the air outlet 114, which facilitates the heat sink 21 to cover the air outlet 114 in the first direction, ensuring that the airflow from the air outlet 114 can pass through the heat sink 21, thereby improving the cooling effect of the cooling airflow on the condenser assembly 2; at the same time, it also avoids the heat sink 21 being too large in the first direction, which would cause waste.

[0080] Furthermore, within the projection plane of the air outlet 114, the orthographic projections of all the heat dissipation fins 213 are located within the range of the orthographic projection of the fan shroud 1. This makes the size of the heat sink 21 more compatible with the size of the air outlet 114, ensuring the cooling effect of the cooling airflow on the condenser assembly 2 while reducing the footprint of the condenser assembly 2 and lowering its cost.

[0081] The bottom of the positioning groove 1112 is provided with a first fixing hole 1113, and the positioning edge 2112 is provided with a second fixing hole 2113. At least two second fixing holes 2113 are provided at intervals along the length of the positioning edge 2112. The first fixing holes 1113 and the second fixing holes 2113 are provided in a one-to-one correspondence. The fan cover 1 and the radiator 21 are connected by fasteners passing through the first fixing holes 1113 and the second fixing holes 2113 to improve the installation convenience and connection stability of the fan cover 1 and the radiator 21. The number of second fixing holes 2113 is preferably 2 to 4.

[0082] The second mounting plate 212 has a recessed protrusion along the direction towards the first mounting plate 211. The protrusion is directly opposite the heat dissipation fins 213. The second mounting plate 212 has two fixing plates located on opposite sides of the protrusion. The protrusion is spaced apart from the air duct base plate 4. The fixing plates are fitted to and detachably connected to the air duct base plate 4, and the condenser section passes through the protrusion. By providing the second mounting plate 212 with the protrusion and fixing plates, the connection between the second mounting plate 212 and the air duct base plate 4 can be made convenient, while creating space between the protrusion and the air duct base plate 4 to avoid the bend section, thereby avoiding interference between the condenser pipe 22 and the air duct base plate 4 and improving the rationality of the structural layout.

[0083] Furthermore, a first clearance hole 411 is provided on the air duct base plate 4, and all the bent pipe sections facing the side of the air duct base plate 4 are located in the first clearance hole 411, so as to further avoid structural interference between the condenser pipe 22 and the air duct base plate 4, and to prevent the radiator 21 from protruding too much from the air duct base plate 4 in the first direction.

[0084] To further improve the condensation effect of the condenser assembly 2, at least two condenser tubes 22 are arranged side by side along the width of the radiator 21. Both condenser tubes 22 are connected to the cooking cavity, thereby reducing the amount of steam in a single condenser tube 22 and improving the condensation effect of steam. The number of condenser tubes 22 can be 2, 3, or 4.

[0085] To collect condensate, a water collection box 5 is installed below the condenser assembly 2. The water collection box 5 contains a water collection chamber, and the lower end of the condensation channel is connected to the water collection chamber. Thus, the condensate formed in the condenser tube 22 flows along the condenser tube 22 to the water collection chamber under the action of gravity, realizing the recovery and cleaning of condensate.

[0086] Furthermore, the lower end of the condenser tube 22 is inserted into the water collection box 5 to ensure that the water in the condenser tube 22 can flow smoothly into the water collection box 5. The upper end of the water collection box 5 is provided with an overflow port, so that the gas in the condenser tube 22 can overflow outward through the overflow port after entering the water collection box 5, thus avoiding excessive gas pressure in the water collection box 5 and affecting the safety of use.

[0087] In this embodiment, the steam module includes a steam generator and a water tank 400. The water tank 400 is provided with a separate water supply chamber and a wastewater chamber. The water supply chamber is used to supply water to the steam generator. The water collection box 5 is connected to the wastewater chamber through a drain pipe, so as to collect and clean the condensate without disassembling the water collection box 5. The configuration of the water tank 400 and the steam generator can refer to the prior art, and will not be limited or described in detail here.
