Description

Technical Field

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

[0002] Steam ovens and other cooking equipment can heat or assist in heating food by heating water to generate high-temperature steam, thus preserving the food's moisture and nutrients. As a result, they are very popular among consumers. However, a large amount of steam is generated during this process, so an exhaust system needs to be installed to remove the steam.

[0003] To address this, Chinese Patent Application No. 201822273963.5 discloses a steam oven with a front-mounted exhaust structure, comprising an oven body and an oven door. The oven body includes a front panel, a control panel assembly, a steaming / baking cavity, and a steam generator. The oven door and the control panel assembly are mounted on the front panel. It also includes an exhaust structure on the oven body, comprising an exhaust connector on the front panel, a rivet on the steaming / baking cavity, and an exhaust conduit connecting the exhaust connector and the rivet. The exhaust connector is movably mounted to the front panel via a first connection structure, and the rivet is riveted to the exhaust port of the steaming / baking cavity. While this design allows the generated steam to be discharged forward, it also presents several drawbacks: 1) High-temperature steam cools rapidly on the inner wall of the exhaust pipe, forming condensate droplets that drip down, posing a risk of food contamination; 2) The exhaust pipe and cavity interface often rely on flange pressing or adhesive bonding, which can easily lead to sealing aging or even steam leakage under long-term high-temperature conditions.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the structure of existing cooking equipment is unreasonable, and condensation easily occurs at the steam outlet, which affects the user experience.

[0006] To solve the above problems, this utility model provides a cooking device, including a cavity and a gas guide hood, with a heat dissipation air duct formed between the gas guide hood and the cavity. The cooking device also includes a gas distribution component and an exhaust connector. The gas distribution component has a duckbill-shaped structure and is located inside the heat dissipation air duct. One end of the exhaust connector is connected to the cavity, and the other end of the exhaust connector is inserted into the gas distribution component, for mixing the steam from the cavity through the gas distribution component before discharging it into the heat dissipation air duct.

[0007] This application utilizes a gas distribution component to ensure uniform mixing of the steam discharged from the cavity. The steam is then discharged into a heat dissipation duct for further mixing. Since the gas in the heat dissipation duct is the gas after cooling the components at the top of the cavity, its temperature is higher than that of the outside air, thus preventing the discharged steam from directly contacting the cold outside air and ensuring that no water droplets are generated at the outlet. The steam and hot air generated in the cavity are guided into the duct through an exhaust connector, resulting in a short exhaust distance and eliminating the need for additional exhaust pipes or other structures, effectively reducing costs.

[0008] Preferably, the air distribution assembly includes a first air distribution plate and a second air distribution plate arranged at an upper and lower position and disposed opposite to each other. The outlet end of the first air distribution plate is provided with a plurality of recesses at intervals. The recesses abut against the second air distribution plate. The spacing between the plurality of recesses gradually decreases from one end near the exhaust connector to the other end. An exhaust section is formed between adjacent recesses. The exhaust section includes a plurality of exhaust holes.

[0009] This configuration allows multiple exhaust holes of different sizes to be formed near the gas distribution assembly, gradually increasing in size from one end near the exhaust connector to the other. Since the steam pressure is higher on the side near the exhaust connector and lower on the other side, this configuration can balance the steam pressure at the near and far ends of the exhaust connector, thereby ensuring uniform distribution and discharge of steam.

[0010] Preferably, the second air distributor has a protrusion at a position corresponding to the recessed portion, the recessed portion and the protrusion abut against each other, and the protrusion and the recessed portion cooperate to form the exhaust portion. This arrangement can further balance the steam pressure within the air distributor assembly, thereby ensuring uniform steam discharge.

[0011] Preferably, the second air distributor is inclined and located below the first air distributor. The second air distributor has a mounting hole for installing an exhaust connector. The second air distributor gradually tilts upward from the mounting hole toward the protrusion.

[0012] This design places the second gas distributor in an oblique triangular shape with the mounting hole at the lowest position. Multiple exhaust sections are at the same height and higher than the mounting hole, forming an overall funnel-shaped structure. This ensures that the condensate generated inside the gas distributor continuously flows back to the mounting hole and is blown outward by the high-temperature airflow inside the gas distributor, thus giving the gas distributor a certain water retention function. When the amount of steam discharged from the cavity decreases in the later stages of cooking, the high-temperature airflow inside the gas distributor slowly dries it, ensuring that no water droplets are discharged from the vent throughout the entire process.

[0013] Preferably, the air distribution assembly is provided with a positioning structure, the positioning structure including a plug-in piece and a plug-in groove, the plug-in piece is located on one of the first air distribution piece and the second air distribution piece, the plug-in groove is located on the other of the first air distribution piece and the second air distribution piece, the plug-in piece can be positioned and assembled into the plug-in groove, and the plug-in groove is a U-shaped opening.

[0014] This design enables rapid assembly of the first and second gas distribution plates, with a simple structure that facilitates production and processing. It allows for fine-tuning of the connectors in different directions within the connector slots, improving assembly tolerance. The rounded corners of the I-shaped holes prevent stress concentration, and under high-temperature steam alternating loads, the crack propagation resistance of the gas distribution assembly connections is significantly improved.

[0015] Preferably, the cooking device further includes a sealing element for sealing the gas distribution assembly and the exhaust connector. The gas distribution assembly has a mounting hole, and the sealing element passes through the mounting hole and is partially higher than the sealing element. The inner wall of the sealing element has multiple vertically arranged spiral ribs for interference fit with the exhaust connector. This design can seal the outside of the exhaust connector, thereby strictly preventing steam from entering the gas distribution assembly through the exhaust connector, resulting in stable and reliable product quality.

[0016] Preferably, an annular edge is provided on the outer periphery of the mounting hole, with the free end of the annular edge extending upward. One end of the seal is provided with an annular groove for limiting and assembling with the annular edge, and the other end of the seal abuts against the gas distribution assembly. This design locks the installation position of the seal through the limiting structures on both sides, preventing abnormal situations such as seal displacement or even detachment during the installation of the exhaust connector, resulting in high installation efficiency.

[0017] Preferably, the cooking device includes a heat insulation plate, with heat insulation cotton disposed between the heat insulation plate and the cavity. The air guide hood is fixedly mounted on the heat insulation plate, and the air guide hood has an adhesive groove on its side near the heat insulation plate to accommodate adhesive and achieve a seal with the heat insulation plate. This arrangement ensures no steam leakage between the air guide hood and the heat insulation plate, and ensures the safe and stable operation of the components at the top of the cavity.

[0018] Preferably, the cooking device includes a door assembly, the cavity has an opening, the door assembly is capable of opening or blocking the opening, a control panel is disposed above the door assembly, an exhaust port is formed on the front side of the air guide cover, and the exhaust port is located between the door assembly and the control panel.

[0019] This design places the exhaust vent in the space between the door assembly and the control panel, eliminating the need for an external independent exhaust pipe, making it suitable for compact kitchen layouts. The exhaust vent is concealed by the edges of the door assembly and control panel, leaving only a narrow air outlet, resulting in a clean appearance and no visual conflict with the control panel.

[0020] Preferably, the cavity includes a top cover plate with an air vent. One end of the exhaust connector has a hexagonal head larger than the air vent, and the other end of the exhaust connector passes through the air vent and is threaded into a fastener. This design allows for quick and easy fixing of the exhaust connector to the air vent of the cavity, resulting in a simple structure and good sealing performance.

[0021] Compared with the prior art, the cooking device described in this utility model embodiment has the following beneficial effects: 1) The steam discharged from the cavity can be evenly mixed by the gas distribution component, and then discharged into the heat dissipation duct for further mixing. Since the gas in the heat dissipation duct is the gas after heat dissipation from the top gas component of the cavity, its temperature is higher than that of the outside air, thus avoiding direct contact between the discharged steam and the outside cold air, ensuring that no water droplets are generated at the outlet; 2) The steam and hot steam generated in the cavity are introduced into the duct by the exhaust connector. The exhaust distance is short, and there is no need to add exhaust pipes or other structures, effectively reducing costs; 3) The second gas distribution plate is funnel-shaped, ensuring that the condensate in the gas distribution component continuously flows back to the mounting hole, giving it a certain water storage function; and when the amount of steam decreases in the later stage of cooking, the generated high-temperature airflow slowly dries it, thus ensuring that no condensate is discharged from the exhaust hole throughout the entire process.

[0037] like Figure 1-9 As shown, a cooking device includes a cavity 1, with an exhaust structure 2 at the top of the cavity 1. The exhaust structure 2 includes a vent 21, which is located above the top of the cavity 1 and forms a heat dissipation duct with the cavity 1. The vent 21 has an exhaust port 211 near the front of the cavity 1. The exhaust structure 2 also includes a duckbill-shaped air distribution component 23, which is located inside the heat dissipation duct and has its outlet facing the exhaust port 211, for discharging steam from the cavity 1 into the heat dissipation duct.

[0038] This application utilizes the gas distribution component 23 to ensure uniform mixing of the steam discharged from the cavity 1. The steam is then discharged into the heat dissipation duct for further mixing. Since the gas in the heat dissipation duct is the gas after cooling the components at the top of the cavity 1, its temperature is higher than that of the outside air, thus preventing the discharged steam from directly contacting the cold outside air and ensuring no water droplets are generated at the outlet. The structure is simple and the production cost is low. The duckbill-shaped structure refers to a structure where the inner cavity is larger on the inlet side and gradually narrows on the outlet side.

[0039] Preferably, the gas distribution component 23 is located in the middle of the heat dissipation duct. This arrangement enables secondary mixing of the exhaust steam, ensuring that the exhaust from the cooking equipment is uniform and gentle, with a low temperature rise to prevent scalding of the user.

[0040] Preferably, the exhaust structure 2 further includes an exhaust connector 27, the cavity 1 includes an upper cover plate 11, the upper cover plate 11 is provided with an exhaust hole 111, one end of the exhaust connector 27 is connected to the exhaust hole 111, and the other end of the exhaust connector 27 is inserted into the gas distribution assembly 23. This arrangement can guide the steam and hot steam generated in the cavity 1 into the air duct, with a short exhaust distance, eliminating the need for additional exhaust pipes and other structures, effectively reducing costs.

[0041] As an example of this utility model, the exhaust structure 2 further includes a fastener 26. One end of the exhaust connector 27 is provided with a hexagonal head, the size of which is larger than the vent hole 111. The other end of the exhaust connector 27 passes through the vent hole 111 and is threadedly connected to the fastener 26. This arrangement allows the exhaust connector 27 to be quickly fixed at the vent hole 111 of the cavity 1, and the structure is simple with good sealing effect.

[0042] As an example of this utility model, the air distribution assembly 23 includes a first air distribution plate 231 and a second air distribution plate 232 connected to each other. The outlet end of the first air distribution plate 231 is provided with a plurality of recesses 2312 at intervals. The recesses 2312 abut against the second air distribution plate 232. The spacing between the plurality of recesses 2312 gradually decreases from one end near the exhaust connector 27 to the other end. An exhaust section 233 is formed between adjacent recesses 2312. The exhaust section 233 includes a plurality of exhaust holes.

[0043] This configuration allows multiple exhaust holes of different sizes to be formed near the gas distribution assembly 23, gradually increasing in size from one end near the exhaust connector 27 to the other. Since the steam pressure is higher on the side near the exhaust connector 27 and lower on the other side, this configuration can balance the steam pressure at the near end and far end of the exhaust connector 27, thereby ensuring that the steam is evenly distributed and discharged.

[0044] Preferably, the second air distribution plate 232 has a protrusion 2325 at a position corresponding to the recess 2312. The recess 2312 and the protrusion 2325 abut against each other, and the protrusion 2312 and the recess 2325 cooperate to form the exhaust section 233. This arrangement can further balance the steam pressure in the air distribution assembly 23, thereby ensuring uniform steam discharge.

[0045] As an example of this utility model, the air distribution assembly 23 is provided with a positioning structure, which includes a plug-in piece 2311 and a plug-in groove 2321. The plug-in piece 2311 is located on one of the first air distribution piece 231 and the second air distribution piece 232, and the plug-in groove 2321 is located on the other of the first air distribution piece 231 and the second air distribution piece 232. The plug-in piece 2311 can be positioned and fitted into the plug-in groove 2321. This arrangement enables rapid assembly of the first air distribution piece 231 and the second air distribution piece 232, has a simple structure, and is easy to manufacture.

[0046] As an example of the present invention, the second gas distributor 232 includes a main body 2323, one side of which is provided with a folded edge 2324. The folded edge 2324 is provided with a plug-in groove 2321, which has an 8-shaped opening. This configuration allows the plug-in piece 2311 to be finely adjusted in different directions within the plug-in groove 2321, improving the assembly error tolerance; the rounded corners of the 8-shaped opening avoid stress concentration, and under high-temperature steam alternating loads, the crack propagation resistance at the connection of the gas distributor assembly 23 is significantly improved.

[0047] Preferably, the second air distributor 232 is inclined and located below the first air distributor 231. The second air distributor 232 is provided with a mounting hole 2326 for mounting an exhaust connector 27. The second air distributor 232 gradually tilts upward from the mounting hole 2326 toward the protrusion 2325.

[0048] This configuration makes the second gas distributor 232 obliquely triangular with the mounting hole 2326 at the lowest position. Multiple exhaust sections 233 are at the same height and higher than the mounting hole 2326, forming a funnel-shaped structure. This ensures that the condensate generated in the gas distributor 23 continuously flows back to the mounting hole 2326 and is blown out by the high-temperature airflow in the gas distributor 23, thus giving the gas distributor 23 a certain water retention function. When the amount of steam discharged from the cavity 1 decreases in the later stage of cooking, the high-temperature airflow in the gas distributor 23 is used to slowly dry it, ensuring that no water droplets are discharged from the vent 111 throughout the entire process.

[0049] Preferably, an annular edge 2322 is provided on the outer periphery of the mounting hole 2326, and the free end of the annular edge 2322 extends upward. The exhaust structure 2 also includes a sealing element 25, which is installed between the mounting hole 2326 and the exhaust connector 27. The end of the sealing element 25 away from the first air distribution plate 231 abuts against the second air distribution plate 232, and the other end of the sealing element 25 is fitted with the annular edge 2322 for limiting. This arrangement locks the installation position of the sealing element 25 through the limiting structures on both sides, avoiding abnormal situations such as the sealing element 25 shifting or even falling off when installing the exhaust connector 27, resulting in high installation efficiency.

[0050] Preferably, the sealing element 25 is a sealing ring, and the inner wall surface of the sealing ring is provided with toothed ribs for interference fit with the exhaust connector 27. The inlet of the sealing ring is funnel-shaped to facilitate the assembly of the exhaust connector 27. This configuration can seal the outside of the exhaust connector 27, thereby strictly restricting steam from entering the gas distribution assembly 23 through the exhaust connector 27, resulting in stable and reliable product quality.

[0051] As an example of this utility model, heat insulation cotton 7 and heat insulation plate 6 are arranged sequentially above the top of the upper cover plate 11. The exhaust connector 27 passes through the air outlet 111, heat insulation cotton 7 and heat insulation plate 6 in sequence and is inserted into the air distribution assembly 23. The upper end of the exhaust connector 27 is set higher than the sealing member 25.

[0052] Due to the risk of deformation of the heat insulation plate 6 and the thickness deviation of the heat insulation cotton 7, this arrangement ensures that the exhaust connector 27 is always surrounded by the seal 25, preventing air and water leakage. Preferably, the exhaust connector 27 is located at the top left front position of the cavity 1, which can prevent condensation from dripping onto the food during the cooking process and affecting the cooking effect.

[0053] As an example of this utility model, the air guide shroud 21 is fixedly mounted on the heat insulation plate 6. The air guide shroud 21 has an adhesive groove 215 on the side near the heat insulation plate 6 for dispensing adhesive to achieve a seal between it and the heat insulation plate 6. This arrangement ensures that there is no steam leakage between the air guide shroud 21 and the heat insulation plate 6, and ensures that the components at the top of the cavity 1 can operate safely and stably.

[0054] Preferably, the cooking device includes a door assembly 4, the cavity 1 has an opening, the door assembly 4 is capable of opening or blocking the opening, a control panel 3 is disposed above the door assembly 4, and the exhaust port 211 is located between the door assembly 4 and the control panel 3.

[0055] This arrangement places the exhaust vent 211 in the space between the door assembly 4 and the control panel 3, eliminating the need for an external independent exhaust pipe, making it suitable for compact kitchen layouts. The exhaust vent 211 is obscured by the edges of the door assembly 4 and the control panel 3, leaving only a narrow air outlet gap, resulting in a clean appearance and no visual conflict with the control panel 3.

[0056] As an example of this utility model, the cooking device also includes a decorative panel 22, which has a clearance opening 221 corresponding to the exhaust port 211. The decorative panel 22, control panel 3, and door assembly 4 together form the front appearance surface of the cooking device. This arrangement allows the decorative panel 22, for example, to use a composite process of brushed stainless steel and matte glass, to create a textural contrast with the touch screen of the control panel 3 and the coated glass of the door assembly 4, thus strengthening the brand's visual language.

[0057] As an example of this utility model, a connecting plate 212 is provided on one side of the air guide shroud 21, and a fixing post 213 is provided on the connecting plate 212 for assembling the electronic control board 5. This arrangement allows the air guide shroud 21 to form an assembly space for the electronic control board 5, eliminating the need for additional supports and improving assembly efficiency.

[0058] Preferably, the air guide shroud 21 forms an air inlet 214 on the side away from the exhaust port 211. This arrangement allows the existing fan of the cooking equipment to blow air into the air guide shroud 21, thereby achieving secondary mixing of steam and further preventing condensation at the exhaust port 211. The cooking equipment also includes a housing 8 and a heating element 9, which is located below the top of the cavity 1. The structure and assembly relationship of the housing 8 are prior art and will not be described in detail here.

[0059] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
