Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a top cover assembly and a cooking appliance having the same. Background Technology

[0002] An electric pressure cooker is a common cooking appliance. It utilizes the principle that water's boiling point increases under high pressure to cook food under pressure. By heating the sealed cooking chamber, the internal pressure rises, resulting in higher temperatures for cooking and faster cooking. After cooking, the high-pressure steam must be released from the pot before safely opening the lid.

[0003] However, when the cooking cavity contains liquid ingredients, such as when cooking porridge, if the steam is released too quickly during the venting process, the liquid will be carried outside the pot, resulting in overflow. Utility Model Content

[0004] This utility model provides a top cover assembly and a cooking appliance having the same, to solve the problem of overflowing liquid in cooking appliances in the related art.

[0005] According to one aspect of the present invention, a cover assembly is provided for covering a pot body. The cover assembly includes: a cover body; an exhaust assembly including an exhaust seat disposed on the cover body, the exhaust seat having an exhaust channel, an air inlet and multiple air outlets, the air inlet and multiple air outlets being connected to the exhaust channel, the air inlet being connected to the cooking cavity of the pot body; and an inflation component disposed on the cover body, the inflation component having an inflation inlet and an inflation outlet, the inflation outlet being connected to the cooking cavity.

[0006] Applying the technical solution of this utility model, the upper cover assembly includes a cover body, an exhaust component, and an inflator. Gas in the cooking cavity of the pot enters the exhaust channel through the air inlet of the exhaust seat and is discharged through multiple air outlets. During the exhaust process, the inflator, located on the cover body, inflates the cooking cavity. The injected cold air lowers the pressure of the air inside the pot and the surface temperature of the food, controlling foam formation and reducing foam in the cooking cavity. Furthermore, the injected gas disperses the foam, reducing the occurrence of overflow.

[0007] Furthermore, the ratio between the sum of the flow areas of the multiple air outlets and the flow area of ​​the inflation outlet is between 1 and 1.2. By adopting this ratio range, a certain exhaust speed can be maintained while controlling foam generation and reducing the occurrence of overflow.

[0008] Furthermore, the distance between the centerline of the air outlet and the centerline of the air inlet is between 40mm and 80mm. Using this size range allows the cold air entering the cooking cavity to be directed towards the food, preventing it from directly entering the exhaust port from the air inlet and being expelled.

[0009] Furthermore, the exhaust assembly also includes a drive component and a sealing component. The sealing component is movably mounted on the cover, and the drive component can move the sealing component to open multiple vents. By using the drive component to move the sealing component, multiple vents can be opened, thereby enabling the cooking appliance to exhaust gas.

[0010] Furthermore, the driving component includes a solenoid valve and a return spring. The valve stem of the solenoid valve can abut against the sealing component to open multiple air outlets, and the return spring can provide a restoring force to the sealing component to block multiple air outlets. Driving the sealing component to move via the solenoid valve to open multiple air outlets and using the return spring to block them has the advantages of simple structure and ease of operation.

[0011] Furthermore, the exhaust assembly also includes a steam box mounted on the cover, with an exhaust seat inserted inside the steam box. Multiple exhaust ports are located within the steam box, and a sealing element is laterally movably mounted within it. The steam box has clearance holes with sealing portions at these holes. The sealing element and the valve stem of the solenoid valve are located on opposite sides of the sealing portion, and the valve stem can abut against the sealing portion to move the sealing element. By placing multiple exhaust ports within the steam box, the exhaust gas can be collected, preventing gas from entering the cover and damaging the components inside.

[0012] Furthermore, the driving component also includes a push rod, and a push rod seat is provided on the cover. The push rod is movably mounted on the push rod seat in a lateral direction. The valve stem of the solenoid valve can abut against the push rod, and the push rod can abut against the sealing component. By setting the push rod as a transmission component, the movement of the sealing component can be facilitated.

[0013] Furthermore, the exhaust assembly also includes an exhaust pipe and a pressure relief valve. The upper end of the exhaust seat has a mounting hole through which the exhaust pipe is installed on the exhaust seat. The pressure relief valve is closable and positioned at the upper end of the exhaust pipe. By sealing the exhaust pipe with the pressure relief valve, pressure cooking of the cooking appliance can be achieved.

[0014] Furthermore, the cover includes a liner and a pressure-bearing cover, and the inflation component includes an air pump, a first inflation pipe connected to the inlet of the air pump, and a second inflation pipe connected to the outlet of the air pump. The inflation inlet is located on the first inflation pipe, the inflation outlet is located on the second inflation pipe, the air pump is mounted on the liner, and the second inflation pipe is connected to the pressure-bearing cover. Using the above-described cover allows the air pump to be installed using the liner, offering advantages such as simple structure and ease of installation.

[0015] According to another aspect of this utility model, a cooking appliance is provided, comprising a pot body and a lid assembly, the lid assembly being disposed on the pot body, and the lid assembly being the aforementioned lid assembly. Gas in the cooking chamber of the pot body enters the exhaust channel through the air inlet of the exhaust seat and is discharged through multiple air outlets. During the exhaust process, an air inflator installed on the lid body can inflate the cooking chamber, thereby using the injected cold air to lower the pressure air inside the pot and the surface temperature of the food, controlling foam formation and reducing foam in the cooking chamber. Furthermore, the injected gas can disperse the foam, reducing the occurrence of overflow. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1 to 7 As shown, this utility model embodiment provides a top cover assembly for covering a pot body. The top cover assembly includes a cover body 10, an exhaust assembly 20, and an inflation component 30. The exhaust assembly 20 includes an exhaust seat 21, which is disposed on the cover body 10. The exhaust seat 21 has an exhaust channel 211, an air inlet, and multiple air outlets 213. The air inlet and multiple air outlets 213 are all connected to the exhaust channel 211. The air inlet is connected to the cooking cavity of the pot body. The inflation component 30 is disposed on the cover body 10. The inflation component 30 has an inflation inlet and an inflation outlet. The inflation inlet is connected to the outside of the cover body 10, and the inflation outlet is connected to the cooking cavity.

[0030] Applying the technical solution of this utility model, the upper cover assembly includes a cover body 10, an exhaust assembly 20, and an inflator 30. Gas in the cooking cavity of the pot enters the exhaust channel 211 through the air inlet of the exhaust seat 21 and is discharged through multiple air outlets 213. During the exhaust process, the inflator 30 installed on the cover body 10 can inflate the cooking cavity, thereby using the injected cold air to reduce the pressure air and surface temperature of the food in the pot, controlling the formation of foam, reducing foam in the cooking cavity, and using the injected gas to disperse the foam, reducing the occurrence of overflow.

[0031] In this embodiment, the ratio between the sum of the flow areas of the multiple air outlets 213 and the flow area of ​​the inflation outlet is between 1 and 1.2. By using the above ratio range, a certain exhaust speed can be maintained, foam generation can be controlled, and the occurrence of overflow can be reduced.

[0032] The ratio between the sum of the flow areas of the multiple air outlets 213 and the flow area of ​​the inflation outlet can be 1, 1.1, 1.2, or any value greater than or equal to 1 and less than or equal to 1.2.

[0033] Specifically, the distance between the centerline of the air outlet and the centerline of the air inlet is between 40mm and 80mm. Using this size range allows the cold air filled into the cooking cavity to be blown towards the food, preventing it from being directly discharged into the exhaust seat 21 from the air inlet.

[0034] The distance between the centerline of the inflation outlet and the centerline of the inflation inlet can be any value of 40mm, 50mm, 60mm, 70mm, 80mm, or greater than or equal to 40mm and less than or equal to 80mm.

[0035] like Figure 1 and Figure 2 As shown, the exhaust assembly 20 also includes a drive member 22 and a sealing member 23. The sealing member 23 is movably disposed on the cover 10. The drive member 22 can drive the sealing member 23 to move, thereby opening multiple air vents 213. By using the drive member 22 to move the sealing member 23, multiple air vents 213 can be opened, thereby realizing the exhaust of the cooking appliance.

[0036] In other embodiments, a manual operating component can be provided to move the sealing component 23 to open multiple air outlets 213.

[0037] Among them, the multiple air outlets 213 include at least two first air outlets, and the at least two first air outlets are all disposed on the exhaust seat 21. The sealing member 23 can open or block at least two first air outlets.

[0038] like Figure 1 and Figure 2 As shown, the driving component 22 includes a solenoid valve 221 and a return spring 222. The valve stem of the solenoid valve 221 can abut against the sealing component 23 to open multiple air outlets 213. The return spring 222 can provide a restoring force to the sealing component 23, so that the sealing component 23 blocks the multiple air outlets 213. By driving the sealing component 23 to move through the solenoid valve 221 to open multiple air outlets 213, and using the return spring 222 to drive the sealing component 23 to block the multiple air outlets 213, it has the advantages of simple structure and easy operation.

[0039] like Figure 2As shown, the exhaust assembly 20 also includes a steam box 24 disposed on the cover 10. An exhaust seat 21 passes through the steam box 24, and multiple exhaust ports 213 are disposed within the steam box 24. A sealing member 23 is movably disposed laterally within the steam box 24. The steam box 24 has a clearance hole with a sealing portion. The sealing member 23 and the valve stem of the solenoid valve 221 are located on opposite sides of the sealing portion, and the valve stem can abut against the sealing portion to move the sealing member 23. By disposing of multiple exhaust ports 213 within the steam box 24, the exhaust gas can be collected using the steam box 24, preventing gas from entering the cover 10 and damaging the components inside the cover 10.

[0040] In this embodiment, the exhaust seat 21 is vertically inserted into the steam box 24, the return spring 222 is sleeved on the sealing member 23, the solenoid valve 221 is disposed outside the steam box 24, and the sealing part is a sealing gasket disposed at the clearance hole.

[0041] like Figure 2 As shown, the driving component 22 also includes a push rod 223. A push rod seat 11 is provided on the cover 10. The push rod 223 is movably mounted on the push rod seat 11 in a lateral direction. The valve stem of the solenoid valve 221 can abut against the push rod 223, and the push rod 223 can abut against the sealing component 23. By setting the push rod 223 as a transmission component, the movement of the sealing component 23 can be facilitated.

[0042] In this process, the valve stem of the solenoid valve 221 drives the push rod 223 to move, and the push rod 223 can then drive the sealing component 23 to move, so as to open multiple air outlets 213.

[0043] Specifically, the size of the push rod 223 is smaller than the size of the valve stem of the solenoid valve 221, which is beneficial for the push rod 223 to cooperate with the sealing component 23.

[0044] like Figure 2 As shown, the exhaust assembly 20 also includes an exhaust pipe 25 and a pressure relief valve 26. An installation hole is provided at the upper end of the exhaust seat 21, through which the exhaust pipe 25 is installed on the exhaust seat 21. The pressure relief valve 26 is closable at the upper end of the exhaust pipe 25. By sealing the exhaust pipe 25 with the pressure relief valve 26, pressure cooking of the cooking appliance can be achieved.

[0045] The multiple vents 213 also include a second vent located at the upper end of the exhaust pipe 25. When venting after pressure cooking, the first and second vents can be opened simultaneously to increase the venting speed.

[0046] In other embodiments, the exhaust seat 21 and the exhaust pipe 25 can be separately disposed on the cover 10.

[0047] Furthermore, the sum of the flow areas of at least two first air outlets is greater than the flow area of ​​the second air outlet. By simply opening at least two first air outlets with the sealing member 23, pressureless cooking of the cooking appliance can be achieved.

[0048] like Figure 1 , Figure 6 as well as Figure 7 As shown, the cover 10 includes a liner 12 and a pressure-bearing cover 13. The inflation component 30 includes an air pump 31, a first inflation pipe connected to the inlet of the air pump 31, and a second inflation pipe connected to the outlet of the air pump 31. The inflation inlet is located on the first inflation pipe, and the inflation outlet is located on the second inflation pipe. The air pump 31 is mounted on the liner 12, and the second inflation pipe is connected to the pressure-bearing cover 13. Using the above-described cover 10, the air pump 31 can be installed using the liner 12, offering advantages such as simple structure and ease of installation.

[0049] The pressure cover 13 is provided with an overflow port so that the second inflation tube can be connected to the cooking cavity.

[0050] In this embodiment, a fixing post is provided on the cover 12, and a fixing hole is provided on the air pump 31. The fixing post passes through the fixing hole to fix the air pump 31 on the cover 12.

[0051] Specifically, the exhaust seat 21 is fixed to the pressure cover 13.

[0052] Another embodiment of this utility model provides a cooking appliance, which includes a pot body and a lid assembly. The lid assembly is placed on the pot body and is the lid assembly provided above. Gas in the cooking cavity of the pot body enters the exhaust channel 211 through the air inlet of the exhaust seat 21 and is discharged through multiple air outlets 213. During the exhaust process, the air inflator 30 provided on the lid 10 can inflate the cooking cavity, thereby using the injected cold air to reduce the temperature of the compressed air and food surface in the pot, controlling the formation of foam, reducing foam in the cooking cavity, and using the injected gas to disperse the foam, reducing the occurrence of overflow.

[0053] The cooking appliances include electric pressure cookers and multi-functional cookers with pressure cooking functions.
