Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a top cover assembly and a cooking utensil. Background Technology

[0002] In cooking appliances such as rice cookers, the cooking cavity and the food inside are heated by placing a heating element at the bottom of the cooking cavity. However, during the heating process, due to the large temperature difference between the top and bottom of the cooking cavity, steam will condense into condensate on the inner surface of the lid of the cooking appliance. The condensate drips into the rice and other food, which will affect the taste and cooking effect. Utility Model Content

[0003] The main purpose of this invention is to provide a top cover assembly and cooking appliance that prevents steam from condensing into water and flowing back to the food, thereby improving the cooking effect.

[0004] To achieve the above objectives, this utility model proposes a top cover assembly, comprising:

[0005] A lid having an inner surface disposed opposite to the cooking cavity of the cooking appliance; and

[0006] An air extraction assembly includes a fan and an air extraction pipe. The fan is located on the cover. At least one end of the air extraction pipe is connected to the fan. The air extraction pipe is located on the inner surface of the cover and is arranged around at least a portion of the cover. The air extraction pipe has several air extraction ports.

[0007] In one embodiment of this application, both ends of the extraction pipe are connected to the fan;

[0008] Alternatively, the air extraction assembly may be provided with at least two air extraction pipes, wherein at least two air extraction pipes are connected to the fan.

[0009] In one embodiment of this application, a groove is formed on the inner surface of the cover, and the air extraction pipe is disposed in the groove and is arranged around the edge of the bottom wall of the groove;

[0010] And / or, the inner surface of the cover is provided with a sealing area, the sealing area being disposed opposite to the cooking cavity of the cooking appliance to seal the cooking cavity, and at least a portion of the exhaust pipe is disposed at the edge of the sealing area and is disposed around at least a portion of the sealing area circumferentially.

[0011] In one embodiment of this application, the cover is provided with an exhaust channel, and the inner surface of the cover is provided with an airflow inlet for the exhaust channel.

[0012] In one embodiment of this application, an installation cavity is formed in the cover, an air inlet communicating with the installation cavity is opened on the inner surface of the cover, a communication port communicating with the installation cavity is opened on the side wall of the exhaust channel, a fan is disposed in the installation cavity, and the exhaust pipe is connected to the air inlet.

[0013] In one embodiment of this application, the air inlet is located in the sealing area, and the air extraction pipe includes a connected extension section and an air extraction section. The extension section extends from the air inlet to the edge of the cover, and the air extraction section is arranged circumferentially around at least a portion of the cover.

[0014] And / or, the air inlet is provided with a pipe joint, and the air extraction pipe is fitted with the pipe joint.

[0015] In one embodiment of this application, the upper cover assembly further includes a fixing structure disposed on the cover body to fix the air extraction pipe.

[0016] In one embodiment of this application, the fixing structure includes a plurality of fixing ribs, which are arranged at intervals along the extension direction of the suction pipe. The two ends of the fixing ribs are connected to the cover to form a through-pipe channel with the cover, and the suction pipe passes through the through-pipe channel.

[0017] In one embodiment of this application, the extraction tube is a flexible tube;

[0018] And / or, the material of the extraction tube is a flexible polymer material;

[0020] This application also proposes a cooking appliance that includes a cover assembly as described in any of the foregoing embodiments.

[0021] The technical solution of this utility model involves setting an extraction component in the upper cover assembly of a cooking appliance. The extraction pipe of the extraction component is arranged around the inner surface edge of the cover body opposite to the cooking cavity, and several extraction ports are opened on the extraction pipe. During the cooking process, since the edge temperature of the inner surface of the cover body is lower, the extraction component removes the steam flowing towards the cold edge area. The surrounding extraction pipe and the several extraction ports on the extraction pipe can quickly remove the steam flowing around the perimeter, thereby effectively preventing the steam from condensing into water at the edge of the cover body and flowing back into the cooking cavity, thus improving the cooking effect of the food. Compared with the method of setting a high-voltage heating component in the upper cover, the method of setting an extraction component in this application is safer. Attached Figure Description

[0038] This utility model proposes a lid assembly 100 for use in a cooking appliance 1, designed to allow steam to escape during cooking and prevent steam condensation from flowing back into the food. It is understood that the cooking appliance 1 is not limited to a specific type of appliance, such as a rice cooker, soup pot, or health pot. For ease of understanding, the following description uses a rice cooker as an example of the cooking appliance 1.

[0039] Please refer to Figures 1 to 7 In some embodiments of this application, the cover assembly 100 includes a cover body 10 and an exhaust assembly 30. The cover body 10 has an inner surface that is disposed opposite to the cooking cavity 210 of the cooking appliance 1. The exhaust assembly 30 includes a fan 31 and an exhaust pipe 33. The fan 31 is disposed on the cover body 10. At least one end of the exhaust pipe 33 is connected to the fan 31. The exhaust pipe 33 is disposed on the inner surface of the cover body 10 and is arranged around at least a portion of the cover body 10 in a circumferential manner. The exhaust pipe 33 has a plurality of exhaust ports 331.

[0040] In this embodiment, the top cover assembly 100 is used in a cooking appliance 1. The main body 200 of the cooking appliance 1 forms a cooking cavity 210 with an open top. The top cover assembly 100 is closable and covers the top opening of the cooking cavity 210, thereby closing or opening the cooking cavity 210. The top cover assembly 100 includes a cover body 10 as the main structure. The cover body 10 can be a one-piece structure, for example, suitable for cooking appliances 1 such as health pots and soup pots; while in cooking appliances 1 such as rice cookers, the cover body 10 can also be a component, for example, the cover body 10 can be composed of a top cover, an inner cover, and a movable cover plate. The cover body 10 is defined to have an inner surface. When the top cover assembly 100 covers the top opening of the cooking cavity 210, the inner surface of the cover body 10 is positioned opposite to the cooking cavity 210.

[0041] An air extraction assembly 30 is disposed on the cover 10. The air extraction assembly 30 includes a fan 31 and an air extraction pipe 33, etc. The air extraction pipe 33 is disposed on the inner surface of the cover 10, and at least a portion of the air extraction pipe 33 is arranged to surround at least a portion of the cover 10 in a circumferential manner. A plurality of air extraction ports 331 are provided on the side wall of the air extraction pipe 33. At least one end of the air extraction pipe 33 is connected to the fan 31. The fan 31 is disposed on the cover 10, and can be disposed inside the cover 10 or on the side of the cover 10 away from the inner surface. The fan 31 can provide driving force to draw steam and other gases from the cooking chamber 210 through the exhaust pipe 33 and discharge the steam to the outside through the fan 31; wherein, the air outlet of the fan 31 can be exposed to the outside for exhaust; or the air outlet of the fan 31 can be connected to an exhaust pipe, so that the exhaust pipe extends to the outside for exhaust; or in the following embodiment, the air outlet of the fan 31 can be connected to an exhaust channel 13 opened on the cover 10, so as to exhaust the gas to the outside through the exhaust channel 13.

[0042] When the cover assembly 100 is used in the cooking appliance 1, the inner surface of the cover 10 faces the cooking cavity 210. Since the edge of the cover 10 is close to the external structure and environment, the temperature of the edge area of ​​the cover 10 is relatively lower than the temperature of the middle of the inner surface of the cover 10. The exhaust pipe 33 is arranged around the edge of the cover 10, so that there are exhaust ports 331 at each edge of the cover 10 to draw away the steam flowing to the edge area of ​​the inner surface of the cover 10, thereby effectively preventing the steam from condensing in the edge area of ​​the inner surface of the cover 10 and causing the condensate to flow back into the cooking cavity 210.

[0043] In some embodiments, the operating state of the vacuum component 30 can be adjusted according to the cooking stage of the cooking appliance 1. Taking rice cooking as an example, the cooking stages of rice cooking can be roughly divided into the heating stage, the boiling stage, and the simmering stage. During the heating and boiling stages, there is still a lot of water in the cooking chamber 210. After entering the simmering stage, the amount of water in the cooking chamber 210 decreases, so it is necessary to avoid condensation dripping into the rice and affecting its taste and aroma. The vacuum component 30 can be activated after the cooking appliance 1 is determined to have entered the simmering stage to extract steam and prevent steam from condensing into water and dripping back into the rice. In the simmering stage, it is also necessary to maintain a relatively high cooking temperature in the early stage, which can be 3-5 minutes before the end of simmering, so that the ingredients can be fully cooked. During this process, the vacuum component 30 can be used to assist in exhausting the steam at a slower speed to prevent the temperature of the cooking chamber 210 from dropping too quickly due to rapid steam exhaust, thus maintaining a higher temperature in the cooking chamber 210. When the rice is almost done cooking, the ingredients are already cooked through. At this point, the suction component can be controlled to increase the suction speed and quickly release the air.

[0044] In addition, in this embodiment, the exhaust pipe 33 may not completely surround the cover 10, that is, a certain gap is left. This arrangement provides a certain amount of redundant space when installing the exhaust pipe 33, and avoids the exhaust pipe 33 being unable to be stably installed on the cover 10 when the length of the exhaust pipe 33 is too long and does not match the circumference of the cover 10.

[0045] Therefore, it is understandable that the technical solution of this application provides an extraction component 30 in the upper cover assembly 100 of the cooking appliance 1, such that the extraction pipe 33 of the extraction component 30 is arranged around the inner surface edge of the cover 10 opposite to the cooking cavity 210, and a plurality of extraction ports 331 are opened on the extraction pipe 33. During the cooking process, since the edge temperature of the inner surface of the cover 10 is low, the steam flowing to the edge cold area is extracted by the extraction component 30, and the surrounding extraction pipe 33 and the plurality of extraction ports 331 opened on the extraction pipe 33 can quickly extract the steam flowing to all directions, thereby better preventing the steam from condensing into water at the edge of the cover 10 and flowing back to the cooking cavity 210, thereby improving the cooking effect of the food. Moreover, compared with the method of setting a high-voltage heating component in the upper cover, the method of setting the extraction component 30 in this application is safer.

[0046] Please refer to Figure 4 and Figure 5 In some embodiments of this application, both ends of the exhaust pipe 33 are connected to the fan 31, or the exhaust assembly 30 is provided with at least two exhaust pipes 33, wherein at least two exhaust pipes 33 are connected to the fan 31.

[0047] In this embodiment, two air inlets 151 can be provided on the fan 31, or in the following embodiment, the mounting cavity 15 of the fan 31 can be provided with two air inlets 151. The suction pipe 33 can be arranged around the inner surface of the cover 10 and have two spaced ends, so that the two ends of the suction pipe 33 are respectively connected to the two air inlets 151. With this arrangement, the fan 31 can simultaneously draw air from both ends of the suction pipe 33, so that the suction ports 331 at all points of the suction pipe 33 have appropriate suction force, thereby improving the steam absorption efficiency. This avoids the situation where only one end of the suction pipe 33 is connected to the fan 31, and the suction force of the suction port 331 at the other end of the suction pipe 33 is too small to draw steam well, thus affecting the steam absorption efficiency at that point.

[0048] In some embodiments, at least two suction pipes 33 may be provided, each suction pipe 33 being disposed on a portion of the inner surface of the cover 10, wherein at least one end of each suction pipe 33 is connected to a fan 31 or a mounting cavity 15 for mounting the fan 31. With this configuration, the fan 31 draws air, generating suction force in each suction pipe 33. Since at least two suction pipes 33 are provided, the length of a single suction pipe 33 is shortened, thereby avoiding the problem that the suction force at the suction port 331 far from the fan 31 is too small due to the excessive length of the suction pipe 33, which may result in poor steam absorption. This ensures that the suction pipes 33 at each edge of the inner surface of the cover 10 maintain a high steam absorption efficiency, thereby effectively preventing steam from condensing at the edge of the inner surface of the cover 10.

[0049] Please refer to Figure 4 and Figure 5 In some embodiments of this application, the two ends of the extraction pipe 33 or two extraction pipes 33 are connected to the opposite sides of the fan 31. This arrangement provides a larger operating space when connecting the end of the extraction pipe 33 to the fan 31 or the mounting cavity 15 of the fan 31, avoids interference with other vent pipes or the other end of vent pipes, and improves installation convenience.

[0050] Please refer to Figure 1 In some embodiments of this application, a groove 19 is formed on the inner surface of the cover 10, and the air extraction pipe 33 is disposed in the groove 19 and is arranged around the edge of the bottom wall of the groove 19.

[0051] In this embodiment, a groove 19 is recessed on the inner surface of the cover 10. The suction pipe 33 is placed in the groove 19 and extends along the edge of the bottom wall of the groove 19, adjacent to the side wall of the groove 19. This allows the groove 19 to limit the suction pipe 33, preventing it from shifting. Furthermore, when the cover assembly 100 is applied to the cooking appliance 1 and closed onto the appliance body 200 to seal the cooking cavity 210, the surface of the cover 10 located outside the groove 19 abuts against the appliance body 200. This arrangement avoids displacement of the suction pipe 33 and eliminates the risk of the suction pipe 33 being trapped between the cover 10 and the appliance body 200, ensuring the structural stability of the suction pipe 33 and the unobstructed flow of its internal pipes, thus enabling more stable steam extraction.

[0052] In some embodiments of this application, the inner surface of the cover 10 is provided with a sealing area 11, which is arranged opposite to the cooking cavity 210 of the cooking appliance 1 to seal the cooking cavity 210. At least a portion of the exhaust pipe 33 is provided at the edge of the sealing area 11 and is arranged around at least a portion of the sealing area 11 in a circumferential manner.

[0053] In this embodiment, when the upper cover assembly 100 is closed over the opening of the cooking cavity 210, the edge of the sealing area 11 can be made to fit tightly against the edge of the opening of the cooking cavity 210. Alternatively, a sealing ring can be provided on the inner surface of the cover body 10, and the sealing ring can be arranged around the cover body 10, thereby improving the sealing ability of the cover body 10 in sealing the cooking cavity 210. At this time, at least part of the exhaust pipe 33 is provided at the edge of the sealing area 11 to extract the steam flowing towards the edge of the sealing area 11. The setting of the sealing area 11 can prevent the entry of low-temperature outside gas into the cooking cavity 210 during the cooking process, which would cause the temperature of the upper cover assembly 100 to drop, resulting in a large amount of steam condensing and flowing back into the cooking cavity 210, thus affecting the cooking effect.

[0054] In some embodiments, a groove 19 may be recessed in the sealing area 11 to limit the suction pipe 33 and prevent the suction pipe 33 from moving or deviating.

[0055] Please refer to Figure 1 In some embodiments of this application, the cover 10 is provided with an exhaust channel 13, and the inner surface of the cover 10 is provided with an airflow inlet 131 for the exhaust channel 13. This configuration allows the exhaust channel 13 to discharge steam flowing towards the center of the cover 10, thereby improving the efficiency of steam discharge and reducing the amount of steam flowing towards the inner surface edge of the cover 10. This enables the extraction assembly 30 to promptly and sufficiently remove steam flowing towards the inner surface edge of the cover 10, preventing condensation on the inner surface of the cover 10 due to delayed steam removal. Furthermore, it eliminates the need to increase the power of the fan 31 to quickly remove steam, thus reducing noise.

[0056] Please refer to Figure 1 In some embodiments of this application, the cover 10 has an installation cavity 15, the inner surface of the cover 10 has an air inlet 151 communicating with the installation cavity 15, the side wall of the exhaust channel 13 has a communication port 133 communicating with the installation cavity 15, the fan 31 is disposed in the installation cavity 15, and the exhaust pipe 33 is communicating with the air inlet 151.

[0057] In this embodiment, a mounting cavity 15 is formed inside the cover 10. The mounting cavity 15 is adjacent to the exhaust channel 13 of the cover 10, and the mounting cavity 15 and the exhaust channel 13 are connected through a connecting port 133. The air inlet 151 of the mounting cavity 15 is opened on the inner surface of the cover 10, and the exhaust pipe 33 is connected to the air inlet 151. The fan 31 is installed in the mounting cavity 15. This arrangement can protect the fan 31 by preventing the fan 31 from directly contacting the high-temperature steam in the cooking cavity 210, thereby improving safety.

[0058] When the fan 31 is started, the exhaust pipe 33 draws steam from the inner surface edge area of ​​the cover 10 and enters the mounting cavity 15 through the air inlet 151. Other airflows, including steam, enter the exhaust channel 13 through the connecting port 133 under the action of the fan 31, and mix with the gas that directly enters the exhaust channel 13 from the airflow inlet 131 before being discharged outward. With this configuration, it is not necessary to provide too many exhaust channels 13 on the cover 10, simplifying the structure of the cover 10.

[0059] In this embodiment, the air inlet 151 of the mounting cavity 15 can be opened at the edge of the inner surface of the cover 10 so that the suction pipe 33 can be directly connected to the air inlet 151, and the suction pipe 33 can be arranged around the inner surface of the cover 10 starting from the air inlet 151; Alternatively, in the following embodiment, both the fan 31 and the air inlet 151 are arranged near the middle of the inner surface of the cover 10, and part of the suction pipe 33 extends from the air inlet 151 to the edge area of ​​the inner surface of the cover 10. In both cases, the suction pipe 33 can be arranged at the edge of the inner surface of the cover 10 and connected to the fan 31.

[0060] Please refer to Figures 2 to 5 In some embodiments of this application, the exhaust pipe 33 includes a connected extension section 333 and an exhaust section 335, the extension section 333 extending from the air inlet 151 toward the edge of the inner surface of the cover, and the exhaust section 335 being arranged circumferentially around at least a portion of the cover 10.

[0061] In this embodiment, the mounting cavity 15 is positioned near the center of the cover 10, so that both the air inlet 151 and the fan 31 are near the center of the inner surface of the cover 10. At this time, one end of the exhaust pipe 33 extends from the air inlet 151 to the edge of the inner surface of the cover 10 as an extension section 333. Then, the exhaust section 335 of the exhaust pipe 33 is arranged around the edge of the inner surface of the cover 10. By positioning the fan 31 near the center of the cover 10, the center of gravity of the upper cover assembly 100 is positioned near the center, preventing the center of gravity of the cover 10 from shifting to the side where the fan 31 is located due to the fan 31 being located at the edge of the inner surface of the cover 10. This avoids the problem of the upper cover assembly 100 tipping over and falling when opening and closing the upper cover assembly 100, thus improving the safety when opening and closing the upper cover assembly 100.

[0062] It should be noted that in this embodiment, a number of air extraction ports 331 may be opened only on the air extraction section 335 of the air extraction pipe 33, or air extraction ports 331 may be opened on both the air extraction section 335 and the extension section 333, so that a portion of the steam located in the middle of the inner surface of the cover 10 can be extracted at the same time, thereby improving the steam extraction and discharge efficiency.

[0063] Please refer to Figure 1 In some embodiments of this application, the air inlet 151 is provided with a pipe connector 17, and the suction pipe 33 is fitted onto the pipe connector 17. The suction pipe 33 can be fitted onto the outside of the pipe connector 17, or it can be inserted into the pipe connector 17, increasing the connection area between the suction pipe 33 and the cover 10, improving the connection strength between the suction pipe 33 and the air inlet 151, and making the suction pipe 33 easier to install and remove.

[0064] Please refer to Figure 1 , Figure 3 as well as Figure 5 In some embodiments of this application, the inner surface of the cover 10 is provided with a fixing structure 50, and the air extraction pipe 33 is fixed to the fixing structure 50.

[0065] In this embodiment, the fixing structure 50 can be a component such as an adhesive, binding, or snap-fit, allowing the fixing tube to be adhered, bound, or snapped onto the cover 10; alternatively, a limiting groove can be formed on the inner surface of the cover 10 as the fixing structure 50, allowing the suction tube 33 to be embedded in the limiting groove. The fixing structure 50 improves the connection strength between the suction tube 33 and the cover 10, enhances the positional stability of the suction tube 33, and prevents the suction tube 33 from shifting or falling off, thereby improving the structural stability of the cover assembly 100 and the performance stability of the suction assembly 30.

[0066] Please refer to Figure 3 and Figure 5In some embodiments of this application, the fixing structure 50 includes a plurality of fixing ribs 51, which are arranged at intervals along the extension direction of the exhaust pipe 33. The two ends of the fixing ribs 51 are connected to the cover 10 to form a through-pipe channel 53 with the cover 10, and the exhaust pipe 33 passes through the through-pipe channel 53.

[0067] In this embodiment, the fixing structure 50 includes a plurality of fixing ribs 51 spaced apart. Each fixing rib 51 is sequentially fixed at different positions along the extension path of the extraction pipe 33, with both ends of the fixing ribs 51 connected to the surface of the cover 10, thereby forming a through-pipe channel 53 between the fixing ribs 51 and the cover 10. The spaced-apart arrangement of adjacent fixing ribs 51 creates an air inlet gap between them, allowing steam to be drawn away by the extraction pipe 33. If both ends of the fixing ribs 51 are fixed on the same plane, the middle of the fixing ribs 51 can be arched. (Refer to...) Figure 1 In some embodiments, the inner surface of the cover 10 is provided with a groove 19. In this case, the two ends of the fixing rib 51 can be connected to the bottom wall and the side wall of the groove 19 respectively, so that the suction pipe 33 is limited to the edge of the bottom wall of the groove 19.

[0068] The suction pipe 33 is sequentially inserted into the through-tube channel 53 formed by each fixed rib 51, thereby limiting and fixing the suction pipe 33 to prevent it from shifting or falling off; and in this way, the suction pipe 33 can also be pulled out from the through-tube channel 53 to facilitate cleaning, maintenance or replacement of the suction pipe 33.

[0069] In some embodiments of this application, the extraction tube 33 is a flexible tube; and / or, the material of the extraction tube 33 is a flexible polymer material.

[0070] In this embodiment, the extraction pipe 33 is a flexible hose, which can be made of flexible polymer materials such as rubber, PVC (polyvinyl chloride), or polyurethane. Alternatively, the extraction pipe 33 can be made of metal. This design allows the extraction pipe 33 to be bent arbitrarily, facilitating its arrangement, installation, and disassembly. For example, in the above embodiment, it is convenient to insert the extraction pipe 33 into or pull it out of the pipe channel 53, allowing for easy cleaning and replacement as needed, resulting in better cleaning performance.

[0071] Please refer to Figures 2 to 5 In some embodiments of this application, the cover assembly 100 further includes a thermostat 70, which is disposed on the inner surface of the cover 10.

[0072] In this embodiment, a thermostat 70 is provided on the upper cover assembly 100 so that when the upper cover assembly 100 is applied to the cooking appliance 1, it can be used to detect the temperature of the cooking cavity 210 during the cooking process. This can be used to determine the cooking progress, and the operating status of the heating components or other devices in the cooking appliance 1 can be controlled based on the temperature of the cooking cavity 210, thereby improving the control accuracy of the cooking process.

[0073] In some embodiments, the operating state of the vacuum assembly 30 needs to be controlled according to the cooking stage to control the vacuuming speed. For example, when it is necessary to maintain the temperature in the cooking chamber 210 so that the food can be fully cooked, the vacuuming speed of the vacuum assembly 30 needs to be lower, so as to avoid steam condensation and avoid the large amount of steam being discharged, which would cause the temperature of the cooking chamber 210 to drop too quickly. At this time, the temperature of the cooking chamber 210 can be monitored by the thermostat 70 to control the speed of the fan 31 in the vacuum assembly 30, so as to avoid the fan 31 speed being too high.

[0074] Please refer to Figure 1 This application also proposes a cooking appliance 1, which includes a lid assembly 100 as described in any of the foregoing embodiments. The cooking appliance 1 is not limited to a specific type of appliance, such as a rice cooker, soup pot, or health pot. The cooking appliance 1 includes a main body 200 and a lid assembly 100. The specific structure of the lid assembly 100 is as described in any of the foregoing embodiments. A cooking cavity 210 with an open top is formed in the main body 200. The lid assembly 100 is closable and covers the top opening of the cooking cavity 210, thereby closing or opening the cooking cavity 210.

[0075] Since the cooking appliance 1 proposed in this application applies all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought by all the foregoing technical solutions, which will not be elaborated here.

[0076] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
