Description

Technical Field

[0001] The present invention relates to the technical field of cooking utensils. Background Art

[0002] Smart cooking appliances are currently available on the market, some of which feature rice storage and automatic rice and water addition. Others include vacuum cookers that improve rice cooking quality, or pure steam-heated cookers. To enhance user convenience, some cookers incorporate components such as storage and heating devices outside the cooker body to reduce weight and size. However, this approach requires multiple channels to connect to the cooker body for multifunctional cooking appliances, resulting in an excessive number of components, a complex structure, and increased costs.

[0003] To this end, the present invention provides a cooking appliance to at least partially solve the problems in the prior art. Summary of the Invention

[0004] The Summary of the Invention introduces a series of simplified concepts that will be further described in the Detailed Description of the Invention. The Summary of the Invention is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] In order to at least partially solve the above problems, the present invention provides a cooking appliance comprising:

[0006] The machine body includes a base, a storage bin and a vacuum pump;

[0007] a pot body, the pot body being removably mounted on the base, the pot body having a cooking space formed therein, the cooking space having an interface communicating with the outside world; and

[0008] A material delivery assembly, the material delivery assembly having a material delivery channel and a vacuum channel, the material delivery assembly being connected to the machine body, one end of the material delivery channel being in communication with the material storage bin, and one end of the vacuum channel being in communication with the vacuum pump;

[0009] In which, the feeding component can move between an initial position and a feeding position. When the feeding component moves to the feeding position, the other end of the feeding channel and the other end of the vacuum channel can be connected to the cooking space through the interface respectively, so as to input materials into the cooking space and / or make the pressure in the cooking space lower than a predetermined pressure.

[0010] The cooking appliance of the present invention integrates automatic material addition and vacuuming functions, thereby increasing the versatility of its cooking functions. The separate structure of the pot and the main body allows for the placement of non-essential components such as the material storage bin and vacuum pump on the main body, reducing the weight and volume of the pot and facilitating user convenience. Furthermore, the various channels for feeding materials into the pot and extracting air from the cooking space are integrated into the feed assembly, reducing the number of components and the overall size of the cooking appliance, making it easier to control and use, and thus lowering costs.

[0011] Optionally, the interface is provided with a first valve and a second valve, the vacuum channel being able to communicate with the cooking space via the first valve, and the material delivery channel being able to communicate with the cooking space via the second valve.

[0020] Optionally, the first valve includes a first drive rod. When the material feeding assembly moves to the material feeding position, the first drive rod can be pushed by the material feeding assembly to open the first valve. The second valve further includes a connecting rod. When the first drive rod moves to a predetermined position, the first drive rod can push the connecting rod to move, and the connecting rod can push the second drive rod to the second open position to open the second valve. The movement direction of the second drive rod is the same as or opposite to that of the first drive rod. In this way, the first and second valves can be opened in a coordinated manner.

[0021] Optionally, the first drive rod is movably disposed through the first valve chamber, and a seal is formed between the first drive rod and the opening of the first valve chamber. The end of the first drive rod facing the feed assembly includes an air extraction communication cavity, which has an opening communicating with the vacuum channel and a through hole communicating with the first valve chamber. This facilitates the feed assembly pressing and pushing the first drive rod to open the second valve, while also facilitating communication between the vacuum channel and the cooking space.

[0022] Optionally, the machine body further includes a steam generating device, the material feeding assembly includes a steam channel, one end of the steam channel is connected to the steam generating device, wherein when the material feeding assembly is moved to the material feeding position, the other end of the steam channel can be connected to the cooking space through the interface to input steam into the cooking space.

[0026] a third driving rod, the third driving rod having a sealing structure for sealing the steam inlet, the third driving rod being movable between a third open position for opening the third valve and a third closed position for closing the third valve, wherein when the material feeding assembly moves to the material feeding position, the third driving rod is pushed to the third open position; and

[0027] The third biasing member is configured to bias the third driving rod toward the third closed position. Thus, the third valve has a simple structure and can be automatically opened as the feeding assembly moves into position, making control easier.

[0028] Optionally, the pot body uses steam input through the steam channel as a primary heating source; or the base and / or the pot body are provided with a heating device, and steam input through the steam channel serves as an auxiliary heating source.

[0042] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with embodiments of the present invention.

[0043] In order to fully understand the embodiments of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0044] The present invention provides a cooking appliance. The cooking appliance according to the present invention may be an electric rice cooker, an electric pressure cooker, or other cooking appliance. Besides cooking rice, the cooking appliance according to the present invention may also have various functions, such as cooking porridge, making soup, and stir-frying. Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, the cooking utensil 1 according to the present invention comprises a body 10 and a pot body 20. The body 10 is used to form the main frame structure of the cooking utensil 1, and is provided with a base 11. The pot body 20 can be placed on the base 11 (see FIG. Figure 2 ) and can be removed from the base 11 (see Figure 1 ). That is, the pot body 20 and the body 10 are arranged in a detachable manner to facilitate the movement of the pot body 20. Therefore, the cooking utensil according to the present invention is configured as a split-type cooking utensil.

[0046] In addition, the body 10 is also provided with a storage bin 12. The storage bin 12 may include a solid material storage bin, which can be used to store solid ingredients such as rice and beans required for cooking. Furthermore, the storage bin 12 may also include a liquid material storage bin for storing liquids such as water. In this embodiment, the water tank 13 can serve as an example of a liquid material storage bin.

[0047] The pot body 20 includes a pot base 21, a pot lid 22, and an inner pot 23 disposed within the pot base 21. The pot base 21 is detachably mounted on the base 11 of the appliance body 10. The inner pot 23 is removably placed within the pot base 21. When the pot lid 22 is closed onto the pot base 21, a cooking space 24 is formed between the pot lid 22 and the inner pot 23.

[0048] Furthermore, the cooking appliance 1 includes a feeding assembly 30. The feeding assembly 30 is used to transport food and / or water from the storage bin 12 to the cooking space 24 of the pot body 20. For example, the feeding assembly 30 can automatically add a predetermined amount of food and / or water to the cooking space 24 in response to user instructions, thereby automating the entire cooking process.

[0049] like Figure 1 、 Figure 2 and Figure 4 As shown, in one embodiment, the feed assembly 30 can be configured in the form of a feed arm having a feed channel 39 extending along the length of the feed arm. It will be understood that the feed channel 39 can include a solid material feed channel 34 for conveying solid food materials and a liquid material feed channel 35 for conveying liquid food materials. The feed arm is connected to the body 10, and one end of the solid material feed channel 34 is connected to the solid material storage bin, and one end of the liquid material feed channel 35 is connected to the liquid material storage bin (i.e., the water tank 13).

[0050] In addition, according to the present invention, the feeding assembly 30 is configured to be movable between an initial position and a feeding position. The initial position can be defined as a position where the feeding assembly 30 is away from the pot body 20. Thus, the feeding assembly 30 will not interfere with the removal and placement of the pot body 20 from the base 11, which is convenient for user operation. The feeding position can be a position where the feeding assembly 30 docks with the pot body 20 to deliver materials and / or water to the cooking utensil. Accordingly, an interface 25 communicating with the cooking space 24 is provided on the pot body 20. When the feeding assembly 30 moves to the feeding position, both the solid material feeding channel 34 and the liquid material feeding channel 35 can be connected to the cooking space 24 of the pot body 20 through the interface 25, so as to facilitate the delivery of food materials and / or water as needed.

[0051] In addition, if Figure 2As shown, the body 10 of the cooking appliance 1 according to the present invention may also include a vacuum pump. Accordingly, a vacuum channel 36 is provided on the feed assembly 30. One end of the vacuum channel 36 can be connected to the vacuum pump, and the other end can be connected to the cooking space 24 via the interface 25 when the feed assembly 30 is in the feed position. Thus, the vacuum pump can be activated to extract air from the cooking space 24, reducing the pressure within the cooking space 24 to below a predetermined pressure. It will be appreciated that the body 20 is provided with a pressure sensing element (not shown) to sense the pressure within the cooking space 24.

[0052] Furthermore, although not shown in the accompanying drawings, the body 10 of the cooking appliance 1 according to the present invention may also include a steam generator. Accordingly, a steam channel 38 is provided on the feed assembly 30. One end of the steam channel 38 can be connected to the steam generator, and the other end can be connected to the cooking space 24 via the interface 25 when the feed assembly 30 is in the feed position, thereby supplying steam into the cooking space 24. The steam supplied through the steam channel 38 can serve as the primary heating source for cooking, meaning that the cooking process is completed entirely by the heat provided by the steam. Alternatively, the steam supplied through the steam channel 38 can serve as an auxiliary heating source, assisting in cooking. In this case, a heating plate or coil plate, etc., can be provided on the base 11 of the body 10, and / or heating wires, etc., can be provided on the sides or top of the pot body 20 as the primary heating source.

[0053] According to the present invention, various channels for conveying materials, water and / or steam into the pot body and for extracting air from the cooking space are integrated on the material conveying assembly, which can reduce the number of parts and the overall volume of the cooking utensil, facilitate use, and help reduce costs.

[0054] Continue to refer Figure 2 、 Figures 5 and 6 The specific structure of the feeding assembly 30 configured as a feeding arm may include an upper shell 31, a lower shell 32 and an intermediate body 33. The upper shell 31 and the lower shell 32 are buckled together to form the overall structure of the feeding assembly 30. The intermediate body 33 is arranged between the upper shell 31 and the lower shell 32. Specifically, the intermediate body 33 is provided with a special rib position so that a solid material feeding channel 34 is formed between the intermediate body 33 and the lower shell 32. In addition, as Figure 6 As shown, three conduits are further disposed between the upper shell 31 and the lower shell 32. A first conduit 301 communicates with the water tank 13 to form a liquid material delivery channel 35. A second conduit 302 communicates with the vacuum pump to form a vacuum channel 36. A third conduit 303 communicates with the steam generator to form a steam channel 38.

[0055] Furthermore, cylindrical and outwardly protruding pivot portions 37 are provided on both sides of the feed arm. Thus, the feed arm can be arranged on the body 10 in a pivotable manner around an axis through the pivot portion 37. Preferably, at least one pivot portion 37 may have a cavity connected to the solid material feed channel 34. When connected to the body 10, the cavity connects the storage bin 12 with the solid material feed channel 34. Further preferably, the body 10 may also include a transmission component (not shown) for conveying materials such as solid food materials in the storage bin 12 to the solid material feed channel 34. In one embodiment, the transmission component may include a transmission screw and a drive member for driving the transmission screw to rotate. Wherein, the transmission screw may preferably be arranged in the cavity of the pivot portion 37.

[0056] like Figure 2 As shown, when the pot body 20 is placed on the base 11, at least the solid material storage bin of the storage bin 12 is located above the pot body 20. When the feeding assembly 30 is in the feeding position, the solid material feeding channel 34 is connected to the storage bin 12 and the cooking space 24 in a roughly inclined posture. In this way, the solid material can be automatically transported by gravity. In addition, the feeding assembly 30 is configured to move between the initial position and the feeding position in a manner that swings approximately in the up and down direction around an axis extending horizontally. Therefore, preferably, the interface 25 of the cooking space 24 is provided at the top of the pot body 20 to facilitate docking with the channel of the feeding assembly 30. In other words, the interface 25 is preferably provided on the pot body cover 22.

[0057] Furthermore, if Figure 3 As shown, the interface 25 is provided with a first valve 26 and a second valve 27. The first valve 26 is used to connect with the vacuum channel 36 of the feed assembly 30 to extract air from the cooking space 24. Therefore, the first valve 26 can also be called a vacuum valve. The second valve 27 is used to connect with the feed channels 39 of the feed assembly 30 (i.e., the solid material feed channel 34 and the liquid material feed channel 35) to input materials and / or water into the cooking space 24. Therefore, the second valve 27 can also be called a mixed input valve. The provision of the first valve 26 and the second valve 27 facilitates control of the connection between the various channels of the feed assembly 30 and the cooking space 24, and helps keep the cooking space 24 sealed when the feed assembly 30 is not connected to the pot body 20. Furthermore, a single interface 25 is required to connect different channels to the cooking space 24, simplifying the structure.

[0058] Continue to refer Figure 3The first valve 26 is a one-way valve having an air extraction hole 203 in communication with the cooking chamber 24 and a seal 204. The seal 204 is located on the side of the air extraction hole 203 facing away from the cooking chamber 24 and can only be opened outward. This ensures that when the vacuum passage 36 of the feed assembly 30 is connected to the cooking chamber 24 via the first valve 26, gas can only be discharged from the cooking chamber 24 through the air extraction hole 203 and cannot enter the cooking chamber 24 through the air extraction hole 203.

[0059] Furthermore, in order to facilitate the communication between the vacuum channel 36 and the air extraction hole 203, the first valve 26 further includes a first valve body 201. The first valve body 201 has a first valve chamber 202. The air extraction hole 203 communicates with the first valve chamber 202 and the cooking space 24. A sealing member 204 is disposed in the first valve chamber 202. Furthermore, the first valve chamber 202 also has an opening communicating with the outside world. The opening can be configured to be compatible with the opening of the vacuum channel 36. Figure 7 As shown, when the material delivery assembly 30 moves to the material delivery position so that the vacuum channel 36 docks with the opening of the first valve chamber 202 , communication with the cooking space 24 can be achieved.

[0060] At this point, if the vacuum pump is activated, a sufficient pressure differential is generated across seal 204, overcoming the elastic force of seal 204 and causing it to deform. This connects cooking space 24 to first valve chamber 202 via extraction hole 203, enabling vacuuming. It will be appreciated that when the vacuum pump is deactivated, even if vacuum passage 36 remains connected to first valve chamber 202, the lack of a sufficient pressure differential across seal 204 effectively disconnects cooking space 24 from vacuum passage 36.

[0061] Then go to Figure 3 The second valve 27 has a feed port 217 and includes a second drive rod 213 and a second biasing member 214. The second drive rod 213 has a blocking structure 218 that is movably disposed between a second closed position in which the blocking structure 218 blocks the feed port 217 and a second open position in which the blocking structure 218 is moved away from the feed port 217. The second biasing member 214 biases the second drive rod 213 toward the second closed position.

[0062] The materials conveyed through the solid material delivery channel 34 are typically granular ingredients such as rice and beans. Therefore, the feed opening 217 is preferably configured in a funnel shape to facilitate the entry of the ingredients into the cooking space 24 and prevent residue. Accordingly, the blocking structure 218 is configured to conform to the shape of the feed opening 217. Furthermore, the second drive rod 213 is preferably configured to move upward to remove the blocking structure 218 from the feed opening 217, thereby preventing the granular ingredients from being blocked and causing residue.

[0063] Preferably, the second valve 27 can be configured to automatically open and close the second valve 27 by pushing the second drive rod 213 in response to the material delivery assembly 30 moving to the material delivery position. The second drive rod 213 can be driven directly by the material delivery assembly 30 or indirectly by other components. In this embodiment, the second drive rod 213 is preferably driven by the first drive rod 205 of the first valve 26.

[0064] Specifically, the second valve 27 further includes a connecting rod 215. The first drive rod 205 of the first valve 26 is movably arranged and can be pushed in response to the movement of the feed assembly 30 to the feed position. The connecting rod 215 is configured in a seesaw manner, with its ends positioned below the first drive rod 205 and the second drive rod 213, respectively. When the first drive rod 205 is pushed downward by the feed assembly 30 and abuts the connecting rod 215, as the feed assembly 30 moves further, the other end of the connecting rod 215 forms a lever structure, pushing the second drive rod 213 upward, thereby opening the second valve 27.

[0065] Furthermore, to ensure that the connection between the vacuum passage 36 and the cooking chamber 24 is not affected, the end of the first drive rod 205 facing the feed assembly 30 is preferably provided with an air extraction communication cavity 206. This cavity has an opening toward the feed assembly 30 and a through-hole 207 communicating with the first valve chamber 202. Furthermore, a seal 208 is provided between the first drive rod 205 and the first valve chamber 202. Thus, when the feed assembly 30 abuts against the first drive rod 205, the vacuum passage 36 can communicate with the cooking chamber 24 through the air extraction communication cavity 206. Simultaneously, the feed assembly 30 can also push the first drive rod 205 to move, thereby driving the second drive rod 213, thereby opening the second valve 27. Alternatively, the rod used to open the second valve 27 can be provided as a separate rod from the first valve 26.

[0066] Similar to the second valve 27, the third valve 28 can also be configured to automatically open and close in response to the material delivery assembly 30 moving to the material delivery position. Figure 4 As shown, the third valve 28 includes a third valve body 209, a third drive rod 219, and a third biasing member 223. The third valve body 209 defines a third valve chamber 210. The third valve chamber 210 includes first and second holes 212 disposed opposite each other. The third drive rod 219 is movably disposed through the first and second holes 212. A seal 222 seals the first end of the third drive rod 219 against the first hole of the third valve chamber 210.

[0067] Furthermore, the third drive rod 219 is provided with a steam communication chamber 220 at its first end, which has an opening communicating with the outside world and a through hole 221. The opening communicating with the outside world is used to connect with the steam passage 38 of the feed assembly 30. The through hole 221 is located within the third valve chamber 210 relative to the seal 222. Thus, the steam passage 38 can communicate with the cooking space 24 via the steam communication chamber 220, the third valve chamber 210, and the second hole 212. Therefore, it can be understood that the second hole 212 can also be referred to as the steam inlet 212.

[0068] Furthermore, the second end of the third driving rod 219 extends from the second hole 212 and, under the biasing action of the third biasing member 223, abuts against the third valve body 209 outside the third valve chamber 210. A sealing structure, such as a plug, may be provided at the second end to seal the second hole 212. Thus, the third driving rod 219 controls the opening and closing of the first valve 26 by controlling the opening and closing of the second hole 212.

[0069] refer to Figure 8 When the feed assembly 30 moves close to the feed delivery position, it presses against the third drive rod 219. As the feed assembly 30 moves further, the third drive rod 219, pushed by the feed assembly 30, overcomes the biasing force of the third biasing member 223 and moves downward, causing the second end to move away from the second hole 212. This allows the third valve chamber 210 to communicate with the cooking space 24 through the second hole 212. At this point, the steam passage 38 mates with the opening of the steam communication cavity 220. As a result, steam within the steam passage 38 can sequentially pass through the steam communication cavity 220, the through hole 221, the third valve chamber 210, and the second hole 212 into the cooking space 24.

[0070] After the material delivery assembly 30 moves away from the material delivery position, the third driving rod 219 moves upward under the biasing force of the third biasing member 223, causing the second end to again abut against the third valve body 209 and seal the second hole 212, thereby closing the third valve 28. The position where the second end seals the second hole 212 can be referred to as the third closed position, and the position where the second end moves away from the second hole 212 can be referred to as the third open position.

[0071] The above structure can enable the third valve 28 to automatically open and close in response to the movement of the material feeding assembly 30, thereby optimizing the control process.

[0072] Furthermore, it will be appreciated that steam input into the cooking space 24 is required during the cooking phase, after the addition of materials has already been completed. Therefore, it is desirable to keep the cooking space 24 airtight to prevent large amounts of steam from leaking out and affecting the cooking effect. Therefore, preferably, the cooking appliance 1 is configured such that when the third valve 28 opens in response to the feed assembly 30 moving to the feed position, the second valve 27 is closed. In other words, the distance the feed assembly 30 travels from its initial position to push the third drive rod 219 to open the third valve 28 is shorter than the distance the feed assembly 30 travels from its initial position to push the second drive rod 213 to open the second valve 27. Thus, when the second valve 27 is open, the third valve 28 is open. Since materials and / or water are being fed into the cooking space 24 during this phase, the open state of the third valve 28 has no effect on this delivery. Furthermore, when the third valve 28 is open, the second valve 27 can be closed, thereby preventing steam from leaking out of the feed inlet 217.

[0073] The above arrangement also applies to the first valve 26 and the second valve 27. That is, when the second valve 27 is open, the first valve 26 can remain open. However, when the first valve 26 is open to evacuate air, the second valve 27 needs to remain closed to seal the cooking space 24. Therefore, the vacuuming operation needs to be performed when the first driving rod 205 does not contact the connecting rod 215.

[0074] It is understood that, as an alternative embodiment, the first drive rod 205 of the first valve 26 can be omitted, and the third drive rod 219 of the third valve 28 can be used as the structure for driving the connecting rod 215. Furthermore, although the first drive rod 205 and the second drive rod 213 move in opposite directions in the above embodiment, they can also move in the same direction. In other words, the second drive rod 213 can also be configured to move downward to open the second valve 27.
