Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a slow cooker that can efficiently stir food. Background Technology

[0002] A slow cooker is a common cooking utensil that cooks food at a low temperature. It is simple and convenient. When using a slow cooker, you should try to avoid opening the lid to check, as this can cause the temperature inside the pot to drop and increase the cooking time. Also, because the degree to which the ingredients are submerged in the broth and the heating temperature are different, the taste and texture of the ingredients on the surface and those at the bottom will differ significantly. During the low-temperature slow cooking process, people will occasionally open the lid and stir the ingredients to prevent them from sticking to the bottom of the pot and to promote even heating.

[0003] While existing slow cookers with stirring functions can stir food without opening the lid, most of them simply rotate the stirring element, making it difficult to quickly flip food from the bottom to the top. This only prevents food from sticking to the bottom and burning, but it cannot effectively promote even heating, resulting in no improvement in the taste and texture of the cooked food. Furthermore, the stirring element in existing slow cookers cannot retract, so when opening the lid, the user must lift the lid vertically upwards to remove the stirring element from the pot, rather than tilting the lid as usual. When lifting the lid vertically upwards, the steam inside the pot can easily burn the user's arms, posing a certain safety hazard. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to invent a slow cooker that can efficiently stir food to solve the technical problems of existing slow cookers with stirring function that make it inconvenient to quickly turn the food from the bottom layer to the top layer, and that the stirring component can easily affect the normal removal of the lid, causing the steam inside the pot to easily burn the user's arms, which poses certain safety hazards.

[0005] The present invention adopts the following technical solution:

[0006] A slow cooker that can efficiently stir food includes: a heating shell, an inner pot, and a lid. The inner pot is located inside the heating shell and has a cavity. The lid is placed on the inner pot.

[0008] The drive assembly includes a motor and a transmission mechanism. The motor is mounted on the pot lid, and the transmission mechanism is adapted to transmit the rotational motion of the motor to the swing limit frame. The motor drives the swing limit frame and the stirring spoon to rotate through the transmission mechanism.

[0009] The oscillating assembly includes: a telescopic mechanism, which drives the oscillating limit frame and the stirring assembly to oscillate; the telescopic mechanism includes an electric push rod, which is hinged to the oscillating limit frame, and the telescopic rod of the electric push rod is hinged to the transmission mechanism.

[0010] Preferably, the transmission mechanism includes: a push frame, a slide rail frame, a support frame, and a guide rod; the push frame is fixedly mounted on the motor output shaft; the slide rail frame is located inside the pot lid and has a guide groove; the support frame is slidably mounted on the push frame; and the guide rod is rotatably mounted at one end of the support frame and is slidably connected to the guide groove on the slide rail frame.

[0011] Preferably, the oscillating assembly further includes: a bracket, a curved groove frame, and a slide rod. The bracket is mounted on a support frame, the curved groove frame is mounted on the bracket, the curved groove frame has a curved groove, and the slide rod is mounted at one end of the stirring spoon and is slidably connected to the curved groove on the curved groove frame.

[0012] Preferably, the distance between the upper end of the curved groove on the curved groove frame and the swing fulcrum of the swing limit frame is less than the distance between the lower end of the curved groove on the curved groove frame and the swing fulcrum of the swing limit frame.

[0013] Preferably, the inner liner has an elliptical cavity, and the guide groove on the slide rail is elliptical.

[0014] Preferably, the telescopic mechanism further includes: a first connecting seat and a second connecting seat, the first connecting seat being mounted on the support frame, the second connecting seat being mounted on the swing limit frame, the electric push rod being hinged to the second connecting seat, and the first connecting seat being hinged to the telescopic rod of the electric push rod.

[0015] Preferably, the slow cooker that can efficiently stir food also includes a protective component, which includes a support rail and a protective soft shell. The support rail is set on the lid, and the protective soft shell is rotatably set on the support rail. A swing limit bracket passes through and is fixed relative to the protective soft shell in the circumferential direction. The protective soft shell is made of a flexible material. The lid, the support rail and the protective soft shell together form a receiving cavity.

[0016] Preferably, one end of the stirring spoon is the stirring end, which is inclined relative to the horizontal plane.

[0017] Preferably, the lid and the inner pot are secured together by a snap fastener.

[0018] The beneficial effects of this utility model are as follows:

[0019] A slow cooker for efficiently stirring food includes: a heating shell, an inner pot, and a lid. The inner pot is located inside the heating shell and has a cavity. The lid is placed on the inner pot. A stirring assembly, suitable for stirring the contents of the inner pot, includes a stirring spoon and a swing limiter. A drive assembly, suitable for rotating the stirring assembly to stir the contents of the inner pot, includes: a motor and a transmission mechanism. The motor is mounted on the lid, and its output shaft passes through the lid and is fixedly connected to the transmission mechanism. The swing limiter is rotatably connected to the transmission mechanism via a horizontal shaft. The stirring spoon is movably mounted on the swing limiter. The motor is suitable for driving the transmission mechanism and the stirring assembly to rotate. A swing assembly, suitable for raising or lowering the stirring spoon, and the swing assembly, stirring assembly, and drive assembly together stir the lower layer of contents in the inner pot. When the stirring spoon stirs the ingredients in the inner pot, the stirring spoon swings back and forth, and the stirring end of the stirring spoon swings up and down. This makes it easy to turn the ingredients from the bottom layer to the top layer, so as to fully stir the ingredients, thereby promoting even heating of the ingredients and improving the taste and texture of the cooked food.

[0020] When the extension rod of the electric push rod extends and drives the swing limit frame, the swing limit frame, the stirring assembly and the slide rod to swing back and reset, the slide rod slides back and resets along the curved groove on the curved groove frame. The slide rod drives the stirring spoon to move back and reset, so that the stirring end on the stirring spoon is closer to the center of the inner pot, which makes it easier to retract the stirring spoon and reduces the possibility of the stirring spoon hitting the inner pot when opening the pot lid, thus making it easier to open the pot lid.

Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a slow cooker that can efficiently stir food includes: a heating shell 10, an inner pot 20, a lid 30, and a handle 31. The inner pot 20 is located inside the heating shell 10 and has a cavity. The cavity is elliptical. The lid 30 is placed on the inner pot 20 and is fixed to the inner pot 20 by a snap fastener to prevent the lid 30 from rotating during stirring. The handle 31 is provided on the lid 30.

[0036] The stirring assembly 40 is suitable for stirring the contents contained in the inner liner 20. The stirring assembly 40 includes a stirring spoon 41 and a swing limit frame 42. One end of the stirring spoon 41 is a stirring end 411. The stirring end 411 is inclined relative to the horizontal plane and has a recess. The stirring spoon 41 is slidably connected to the swing limit frame 42.

[0037] The drive assembly 50 is mounted on the pot lid 30 and is used to rotate the stirring assembly 40 to stir the contents in the inner pot 20. The drive assembly 50 includes a motor 51 and a transmission mechanism 52. The motor 51 is mounted on the pot lid 30 and the transmission mechanism is used to transmit the rotational motion of the motor to the swing limit frame. The motor drives the swing limit frame and the stirring spoon to rotate through the transmission mechanism.

[0038] The oscillating component 60, mounted on the drive component 50, is used to raise or lower the stirring spoon 41. The oscillating component 60, the stirring component 40, and the drive component 50 are used together to stir the lower contents contained in the inner liner 20. The oscillating component 60 includes a telescopic mechanism 61, which is used to drive the oscillating limit frame 42 and the stirring component 40 to oscillate. The telescopic mechanism 61 includes a first connecting seat 611, a second connecting seat 612, and an electric push rod 613. The first connecting seat 611 is mounted on the support frame 523, the second connecting seat 612 is mounted on the oscillating limit frame 42, and the electric push rod 613 is hinged to the second connecting seat 612. The first connecting seat 611 is hinged to the telescopic rod of the electric push rod 613. The electric push rod 613 is a miniature DC electric push rod with a rated thrust of about 30N and a length of about 6 cm.

[0039] When it is necessary to stir the food in the inner pot 20, the electronic control module controls the extension rod of the electric push rod 613 to retract. The retraction of the extension rod of the electric push rod 613 causes the swing limit frame 42, the stirring component 40, and the slide rod 64 to swing. The stirring end 411 of the stirring spoon 41 contacts the food in the inner pot 20. The electronic control module controls the output shaft of the motor 51 to rotate slowly. The output shaft of the motor 51 drives the transmission mechanism 52, the swing component 60, and the stirring component 40 to rotate slowly. The stirring spoon 41 rotates slowly to stir the food in the inner pot 20 to prevent the food from sticking to the bottom of the pot. Then, when stirring is not needed, the electronic control module controls the extension rod of the electric push rod 613 to extend. The swing limit frame 42, stirring component 40 and sliding rod 64 swing back to reset, and the stirring end 411 of the stirring spoon 41 separates from the food in the inner pot 20. Since the stirring end 411 of the stirring spoon 41 is tilted, the food can slide off the stirring end 411, thereby reducing the amount of food residue in the recess of the stirring end 411. Then, when the pot lid 30 is opened, the stirring component 40, driving component 50 and swing component 60 provided on the pot lid 30 will not affect the opening of the pot lid 30. The user can directly tilt the pot lid 30 and then remove the pot lid 30. When the pot lid 30 is tilted, it can block and guide the steam, reduce the contact between the steam and the user's arm, and improve safety.

[0040] When the stirring spoon 41 stirs the food in the inner pot 20, the telescopic rod of the electric push rod 613 reciprocates, causing the swing limit frame 42, the stirring spoon 41 and the slide rod 64 to rotate back and forth. When the stirring spoon 41 swings back and forth, the stirring end 411 of the stirring spoon 41 swings up and down, so that the stirring end 411 of the stirring spoon 41 rotates and swings up and down at the same time, which makes it easy to stir the food thoroughly and to turn the lower layer of food to the upper layer, thereby promoting the food to be heated evenly and thus improving the taste and texture of the cooked food.

[0041] Preferably, in order to further promote even heating of the food, in this embodiment, such as Figure 7 , Figure 8 and Figure 9 As shown, the transmission mechanism 52 includes: a push frame 521, a slide rail frame 522, a support frame 523, and a guide rod 524; the push frame 521 is fixedly mounted on the output shaft of the motor 51, and the push frame 521 is provided with a mounting groove; the slide rail frame 522 is located inside the pot lid 30, and the slide rail frame 522 is provided with a guide groove; the support frame 523 is slidably mounted on the mounting groove of the push frame 521; the guide rod 524 is rotatably mounted on one end of the support frame 523, and the guide rod 524 is slidably connected to the guide groove on the slide rail frame 522; the guide groove on the slide rail frame 522 is elliptical.

[0042] When the output shaft of motor 51 drives the transmission mechanism 52, the oscillating component 60 and the stirring component 40 to rotate slowly, the output shaft of motor 51 drives the guide rod 524 to rotate in the guide groove on the slide rail frame 522. The guide rod 524 slides along the mounting groove of the push frame 521, so that the guide rod 524, the support frame 523, the oscillating limit frame 42, the stirring component 40 and the oscillating component 60 rotate along the guide groove on the slide rail frame 522, so that the rotation trajectory of the stirring spoon 41 is elliptical. The rotation trajectory of the stirring spoon 41 matches the shape of the cavity of the inner pot 20. When the cavity shape of the inner pot 20 is circular or other shapes, the guide groove on the slide rail frame 522 can also be other matching shapes, so that the stirring spoon 41 can more fully stir the food in the inner pot 20 and further promote the food to be heated evenly.

[0043] Preferably, in order to more thoroughly agitate the food in the inner pot 20 and to easily open the lid 30, in this embodiment, as follows: Figure 7 , Figure 8 and Figure 9 As shown, the swing assembly 60 also includes: a bracket 62, a curved groove frame 63, and a slide rod 64. The bracket 62 is mounted on the support frame 523, the curved groove frame 63 is mounted on the bracket 62, and a curved groove is formed on the curved groove frame 63. The slide rod 64 is mounted on one end of the stirring spoon 41 and is slidably connected to the curved groove on the curved groove frame 63. The distance between the upper end of the curved groove on the curved groove frame 63 and the swing fulcrum of the swing limiting frame 42 is less than the distance between the lower end of the curved groove on the curved groove frame 63 and the swing fulcrum of the swing limiting frame 42.

[0044] When the telescopic rod of the electric push rod 613 retracts, it drives the swing limit frame 42, the stirring assembly 40, and the slide rod 64 to swing. The slide rod 64 slides along the curved groove on the curved groove frame 63, causing the stirring spoon 41 to move. Because the distance between the upper end of the curved groove on the curved groove frame 63 and the swing fulcrum of the swing limit frame 42 is less than the distance between the lower end of the curved groove on the curved groove frame 63 and the swing fulcrum of the swing limit frame 42, the stirring end 411 on the stirring spoon 41 fits more closely to the inner surface of the inner liner 20. This avoids the stirring end 411 on the stirring spoon 41 being too close to the center of the inner liner 20, thus preventing damage caused by the stirring end 411 being too close to the center of the inner liner 20. The stirring is not sufficient, which allows the stirring spoon 41 to stir the food in the inner pot 20 more thoroughly. When the extension rod of the electric push rod 613 extends and drives the swing limit frame 42, the stirring component 40 and the slide rod 64 to swing back to reset, the slide rod 64 slides back to reset along the curved groove on the curved groove frame 63. The slide rod 64 drives the stirring spoon 41 to move back to reset, so that the stirring end 411 on the stirring spoon 41 is closer to the center of the inner pot 20, which makes it easier to put the stirring spoon 41 away and reduces the possibility of the stirring spoon 41 touching the inner pot 20 when the pot lid 30 is opened, thus making it easier to open the pot lid 30.

[0045] Preferably, in order to protect the food inside the inner pot 20 from contamination and to reduce the difficulty of subsequent cleaning, in this embodiment, such as Figure 4 and Figure 5 As shown, it also includes a protective component 70, which is used to block moisture and stains. The protective component 70 includes a supporting circular rail 71 and a protective soft shell 72. The supporting circular rail 71 is set on the pot lid 30, and the protective soft shell 72 is rotatably set on the supporting circular rail 71. The swing limit frame 42 passes through and is fixed relative to the protective soft shell 72 in the circumferential direction. The protective soft shell 72 is made of flexible material. The protective soft shell 72 will not affect the swing of the swing limit frame 42, and the rotation of the swing limit frame 42 can drive the protective soft shell 72 to rotate on the supporting circular rail 71. The pot lid 30, the supporting circular rail 71 and the protective soft shell 72 together form a receiving cavity.

[0046] The protective soft shell 72 uses food-grade silicone as its flexible material. Food-grade silicone has a smooth surface, is not easy to adhere to stains, and can reduce the difficulty of cleaning.

[0047] When the output shaft of motor 51 drives the transmission mechanism 52, the swing assembly 60 and the stirring assembly 40 to rotate slowly, the swing limit frame 42 rotates horizontally, causing the protective soft shell 72 to rotate horizontally. When the swing limit frame 42 rotates up and down, it squeezes and deforms the protective soft shell 72. When the food in the inner pot 20 is heated and splashes, the protective soft shell 72 blocks the splashes. When the food in the inner pot 20 is heated and generates steam, the protective soft shell 72 blocks the steam. The protective soft shell 72 also blocks the liquid droplets attached to the lid 30 and the surface of the protective soft shell 72. In this way, the drive assembly 50, part of the swing limit frame 42, part of the stirring spoon 41 and the swing assembly 60 inside the protective soft shell 72 are protected. This can prevent some of the dirt inside the protective soft shell 72 from falling into the inner pot 20, thereby ensuring that the food in the inner pot 20 is not contaminated and reducing the difficulty of subsequent cleaning.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
