Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] Existing cooking utensils, such as electric rice cookers and pressure cookers, generally include a pot body and a pot cover. The pot body is provided with an inner pot and a heating device for heating the inner pot. The inner pot is generally made of metal. When the heating device is powered on, it can transfer heat to the inner pot to cook the rice in the inner pot. However, such cooking utensils may stick to the pot during the cooking process, making it difficult to clean the inner pot after the meal, which deteriorates the user experience.

[0003] In order to solve this technical problem, the applicant has previously applied for a moist film 0 coating technology, which sets a cooling fan on the pot body. The cooling fan operates to form a flowing airflow to cool the inner pot, so that the high-temperature steam inside the inner pot condenses and liquidizes into condensed water when it comes into contact with the inner pot, so as to form a layer of water film between the food and the inner wall of the inner pot, preventing the food from sticking to the inner wall of the inner pot and achieving a non-stick effect.

[0004] Most models will set the cooling fan on the side of the pot body. The cold air from the cooling fan is guided by the air guide and blows obliquely from one side of the inner pot to the bottom of the inner pot. However, the cold air reaching the bottom tends to flow directly from the side to the exhaust port between the flange of the inner pot and the edge of the pot body and out from there. The airflow reaching the other side of the bottom of the inner pot is relatively small, and the cooling effect at the bottom of the inner pot is relatively insufficient. In addition, the overall air cooling area is small, which is prone to uneven cooling. The heating device is mostly located at the bottom of the inner pot. The temperature at the bottom of the inner pot is higher, and the air cooling demand is also higher. Therefore, its non-stick effect can be further improved. Utility Model Content

[0005] The utility model provides a cooking utensil to solve the problem that the cold air flow of the existing cooking utensil blowing toward the inner pot is easy to flow directly to the exhaust port from the side, the cooling effect on the bottom of the inner pot is poor, and the non-stick effect can be further improved.

[0006] The technical solution adopted by the utility model is:

[0007] A cooking utensil comprises a pot body and an inner pot placed in the pot body, the pot body is provided with a cooling fan, the pot body comprises a heat preservation ring surrounding the outer periphery of the inner pot, a partition is provided between the heat preservation ring and the inner pot, the partition divides the space between the heat preservation ring and the inner pot into a first cooling cavity located below the partition, and a second cooling cavity located above the partition, the second cooling cavity surrounds at least a part of the outer periphery of the inner pot, the cooling fan is connected with the first cooling cavity, and the partition is also provided with a connecting port connecting the first cooling cavity and the second cooling cavity.

[0008] The cooking utensil of the present invention also has the following additional technical features:

[0009] The separator is arranged on the inner wall of the heat preservation ring and protrudes toward the inner container, and the separator extends along the circumference of the inner container.

[0010] The partition extends along the circumference of the inner tank, and has a raised section that bends and extends upward, the raised section encloses an air inlet space, and the insulation ring is provided with an air inlet connected to the cooling fan corresponding to the air inlet space, and the air inlet is located below the partition.

[0011] The air inlet space has an opening facing the first cooling cavity, and an edge of the opening is provided with an air guiding transition surface for guiding the airflow in the air inlet space to diffuse into the first cooling cavity.

[0012] The width of the air inlet space is greater than the width of the air inlet.

[0013] The heat preservation ring is provided with an air outlet communicating with the second cooling cavity and the outside of the heat preservation ring, and a wind-blocking convex rib is arranged between the communicating port and the air outlet.

[0014] The air outlet is located above the connecting port, the wind shielding rib is located between the connecting port and the air outlet, and the wind shielding rib has flow passages at both ends along the circumferential direction of the insulation ring.

[0015] The region of the inner liner and / or the heat-insulating ring corresponding to the second cooling cavity has a curved portion which is concave in a direction away from the second cooling cavity.

[0016] There are two cooling fans which are arranged on both sides of the insulation ring in a radial direction of the pot body, and the connecting port is staggered with the cooling fans; or, the insulation ring has an air inlet side and a connecting side which are arranged oppositely, there is at least one cooling fan which is placed on the air inlet side, and the connecting port is located on the connecting side.

[0017] The pot body also includes an electromagnetic wire coil arranged below the inner pot, the inner pot includes a bottom wall, a side wall and a transition section between the bottom wall and the side wall, the first cooling chamber includes a first gap between the transition section and the electromagnetic wire coil, and a second gap between the bottom wall and the electromagnetic wire coil, and the first gap is smaller than the second gap.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, by setting a partition between the heat preservation ring and the inner liner, the space between the heat preservation ring and the inner liner is divided into two cavities, the upper and lower cavities, and the cooling fan is connected to the first cooling cavity below, so that the airflow blown by the cooling fan will first enter the first cooling cavity below, and under the action of the partition, the bottom of the inner liner is cooled by air first, and then flows upward along the outer wall of the inner liner, enters the second cooling cavity above through the connecting port on the partition, and flows horizontally in the second cooling cavity to surround at least part of the inner liner, forming a spiral airflow to cool the side of the inner liner. In this way, the priority of air cooling and cooling in the bottom area of ​​the inner liner is improved, the heat concentration area at the bottom of the inner liner is cooled first, the formation of the water-moistening film at the bottom of the inner liner is accelerated, and the non-stick effect of the bottom of the inner liner is improved, and a spiral airflow can be formed on the side of the inner liner, extending the contact area between the air-cooling airflow and the inner liner, improving the cooling effect on the inner liner, increasing the overall air-cooling area of ​​the inner liner, making the overall cooling effect of the inner liner more uniform, and improving the user experience.

[0020] 2. As a preferred embodiment of the utility model, the partition extends along the circumference of the inner liner, and the partition has a raised section that bends and extends upward, and the raised section encloses an air inlet space. The insulation ring is provided with an air inlet connected to the cooling fan corresponding to the air inlet space, and the air inlet is located below the partition. The raised section of the partition that bends upward encloses the air inlet space, and the air inlet is arranged in the air inlet space. On the one hand, on the basis of ensuring that the air inlet is located below the partition and the air-cooled airflow enters the first cooling cavity below first, the cooling fan is arranged at a higher position, thereby avoiding the crowded structure below the insulation ring and the interference with the cooling fan, and improving the space utilization rate; on the other hand, the air inlet space can also converge and guide the airflow at the air inlet, so that the airflow at the air inlet flows downward into the first cooling cavity. In addition, the air inlet space also increases the space between the cooling fan and the inner liner, which helps to reduce the wind resistance of the airflow when entering from the air inlet, and improves the effect of the cooling fan conveying the airflow to the first cooling cavity and the final air cooling effect.

[0021] 3. As a preferred embodiment of the utility model, the insulation ring is provided with an air outlet connecting the second cooling cavity and the outside of the insulation ring, and a wind shield rib is provided between the connecting port and the air outlet. After the airflow in the first cooling cavity enters the second cooling cavity through the connecting port, it cannot flow directly to the air outlet due to the obstruction of the wind shield rib, but can only flow along the extension direction of the wind shield rib, which helps to flow horizontally in the second cooling cavity to form a spiral airflow surrounding the inner liner, prolonging the time of the airflow in the second cooling cavity and the contact time with the inner liner, thereby improving the air cooling effect.

[0022] 4. As a preferred embodiment of the utility model, the area of ​​the inner liner and / or the insulation ring corresponding to the second cooling cavity has a curved portion that is concave in the direction away from the second cooling cavity. The setting of the curved portion can widen the width of the second cooling cavity, reduce the flow resistance of the airflow in the second cooling cavity, enable the airflow to flow more smoothly in the second cooling cavity, and enable the airflow to have better and more complete contact with the inner liner in the second cooling cavity, thereby improving the air cooling effect.

[0023] 5. As a preferred embodiment of the utility model, the pot body also includes an electromagnetic wire coil arranged below the inner pot, the inner pot includes a bottom wall, a side wall and a transition section between the bottom wall and the side wall, the first cooling chamber includes a first gap between the transition section and the electromagnetic wire coil, and a second gap between the bottom wall and the electromagnetic wire coil, the first gap is smaller than the second gap. After the air-cooled airflow enters the first cooling chamber, it flows downward along the inner pot and passes through the first gap and the second gap in sequence. The first gap has a smaller flow diameter than the second gap, and the flow speed of the airflow in the first gap is faster, thereby accelerating the airflow and allowing the air-cooled airflow to enter the second gap at a faster speed. The flow diameter of the second gap is larger, and after the airflow enters at a faster flow rate, it will quickly diffuse in the second gap and flow horizontally under the guidance of the bottom of the inner pot, thereby causing a part of the airflow to flow from the bottom of the inner pot, fully contact the bottom of the inner pot, and take away the heat of the bottom of the inner pot, while a part of the airflow flows along the circumference of the inner pot, thereby forming a cooling ring at the bottom of the inner pot, and rapidly cooling the bottom of the inner pot.

[0044] like Figure 1 , Figure 2 , Figure 4 As shown, a cooking utensil comprises a pot body 1 and an inner pot 2 placed in the pot body 1, the pot body 1 is provided with a cooling fan 3, the pot body 1 comprises a heat preservation ring 4 surrounding the outer periphery of the inner pot 2, a partition 5 is provided between the heat preservation ring 4 and the inner pot 2, the partition 5 divides the space between the heat preservation ring 4 and the inner pot 2 into a first cooling cavity 11 located below the partition 5, and a second cooling cavity 12 located above the partition 5, the second cooling cavity 12 surrounds at least a part of the outer periphery of the inner pot 2, the cooling fan 3 is connected with the first cooling cavity 11, and the partition 5 is further provided with a connecting port 51 connecting the first cooling cavity 11 and the second cooling cavity 12.

[0045] It can be understood that the first cooling chamber 11 corresponds to the bottom of the inner liner 2, or corresponds to a part of the bottom and side of the inner liner 2, and the second cooling chamber 12 corresponds to the side of the inner liner 2, or corresponds to the middle and upper part of the side of the inner liner 2. The first cooling chamber 11 and the second cooling chamber 12 constitute an air duct for the flow of air-cooling air, and the air-cooling air flows in the first cooling chamber 11 and the second cooling chamber 12 in turn, contacts various parts of the inner liner 2, and cools the inner liner 2.

[0046] In the utility model, a partition 5 is provided between the insulation ring 4 and the inner liner 2 to divide the space between the insulation ring 4 and the inner liner 2 into two upper and lower cavities, and the cooling fan 3 is connected to the first cooling cavity 11 below, so that the airflow blown by the cooling fan 3 will first enter the first cooling cavity 11 below, and under the action of the partition 5, the bottom of the inner liner 2 is preferentially cooled by air, and then flows upward along the outer wall of the inner liner 2, enters the second cooling cavity 12 above through the connecting port 51 on the partition 5, and flows horizontally in the second cooling cavity 12 to surround at least a part of the area of ​​the inner liner 2, forming a spiral airflow to cool the side of the inner liner 2. This not only increases the priority of air cooling in the bottom area of ​​the inner liner 2, gives priority to cooling the heat concentrated area at the bottom of the inner liner 2, accelerates the formation of a moist film at the bottom of the inner liner 2, and improves the non-stick effect of the bottom of the inner liner 2, but also forms a spiral airflow on the side of the inner liner 2, extends the contact area between the air-cooled airflow and the inner liner 2, improves the cooling effect on the inner liner 2, increases the overall air cooling area of ​​the inner liner 2, makes the overall cooling effect of the inner liner 2 more uniform, and improves the user experience.

[0047] It should be noted that the present invention does not limit the assembly method of the separator 5, which can be one of the following embodiments:

[0048] Implementation method 1: In this implementation method, Figure 3 , Figure 4 As shown, the separator 5 is arranged on the inner wall of the insulation ring 4 and protrudes toward the inner pot 2, and the separator 5 extends along the circumference of the inner pot 2. Specifically, the separator 5 is a convex rib integrally formed with the insulation ring 4 to save the subsequent assembly step of the separator 5. The separator 5 extends along the circumference of the inner pot 2, and a part of the area has a notch to form a connecting port 51. Of course, the separator 5 can also be set separately from the insulation ring 4 and assembled to the inner wall of the insulation ring 4 later. In addition, this embodiment also avoids processing the inner pot 2, thereby improving the versatility of the inner pot 2.

[0049] Embodiment 2: In this embodiment, the separator 5 is disposed on the outer wall of the inner liner 2 and protrudes toward the heat preservation ring 4. The separator 5 can be integrally formed with the inner liner 2, or can be fixed to the outer wall of the inner liner 2 by subsequent assembly.

[0050] Embodiment 3: In this embodiment, the separator 5 is a component independent of the heat preservation ring 4 and the inner pot 2 , which is fixed to the pot body 1 and located between the heat preservation ring 4 and the inner pot 2 .

[0051] Preferably, if Figure 3 As shown, the partition 5 extends along the circumference of the inner tank 2, and the partition 5 has a raised section 52 that bends and extends upward, and the raised section 52 encloses an air inlet space 53. The insulation ring 4 is provided with an air inlet 44 connected to the cooling fan 3 corresponding to the air inlet space 53, and the air inlet 44 is located below the partition 5.

[0052] The upwardly bent raised section 52 of the partition 5 encloses an air inlet space 53, and the air inlet 44 is arranged in the air inlet space 53. On the one hand, the air inlet 44 is located below the partition 5, so that the air-cooled airflow preferentially enters the first cooling cavity 11 below, and the cooling fan 3 is arranged at a higher position, thereby avoiding the crowded structure below the insulation ring 4 and interfering with the cooling fan 3, thereby improving the space utilization. On the other hand, the air inlet space 53 can also converge and guide the airflow at the air inlet 44, so that the airflow at the air inlet 44 flows downward into the first cooling cavity 11. In addition, the air inlet space 53 also increases the space between the cooling fan 3 and the inner liner 2, which helps to reduce the wind resistance encountered by the airflow when entering from the air inlet 44, and improves the effect of the cooling fan in conveying the airflow to the first cooling cavity and the final air cooling effect.

[0053] Specifically, Figure 3 , Figure 4 As shown, the raised section 52 has a vertical extension section 521 and a transverse extension section 522. The vertical extension section 521 constitutes the two side walls 23 of the air inlet space 53 and is located on the left and right sides of the air inlet 44. The transverse extension section 522 constitutes the top wall of the air inlet space 53 and is located on the upper side of the air inlet 44. The airflow entering from the air inlet 44 can only flow downward into the first cooling chamber 11 due to the obstruction of the vertical extension section 521 and the transverse extension section 522.

[0054] Furthermore, if Figure 3 , Figure 6 As shown, the air inlet space 53 has an opening 531 facing the first cooling cavity 11 , and an edge of the opening 531 is provided with an air guiding transition surface 532 for guiding the airflow in the air inlet space 53 to disperse and enter the first cooling cavity 11 .

[0055] Since the airflow in the air inlet space 53 is blocked by the partition 5 on the upper side and the left and right sides, it can only flow downward from the lower opening 531 into the first cooling chamber 11. An air guide transition surface 532 is provided at the edge of the opening 531, so that the opening 531 is an open structure, and the airflow in the air inlet space 53 is guided by the air guide transition surface 532 and diffused into the first cooling chamber 11, thereby increasing the contact area between the airflow and the bottom of the inner liner 2.

[0056] The wind guide transition surface 532 can be Figure 6 The arc surface shown in the figure may also be an inclined surface or an irregular curved surface, etc., as long as it can guide the airflow to diffuse and flow, and is not limited here.

[0057] Preferably, if Figure 6As shown, the width of the air inlet space 53 is greater than the width of the air inlet 44, thereby increasing the space at the air inlet 44, helping to reduce the wind resistance encountered by the air flow when entering from the air inlet 44, increasing the air flow speed, and improving the air cooling effect.

[0058] Preferably, if Figure 6 As shown, the width dimension A of the raised section 52 is greater than 6 mm. Thus, the wind flow can be effectively blocked. Furthermore, the utility model does not limit the positional relationship between the raised section 52 and the inner liner 2. In one embodiment, the raised section 52 abuts against the inner liner 2, thereby positioning the placement of the inner liner 2, and at the same time blocking the gap between the raised section 52 and the inner liner 2 to prevent the wind flow entering at the air inlet 44 from directly flowing up from the gap into the second cooling chamber 12. In another embodiment, there is a small gap between the raised section 52 and the outer surface of the inner liner 2. Due to the width of the raised section 52 itself, the gap is relatively narrow and long, and it is also difficult for the air flow to flow from the gap into the second cooling chamber 12. At the same time, it can also avoid interference between the raised section 52 and the inner liner 2, or scratches on the surface of the inner liner 2.

[0059] Preferably, if Figure 1 As shown, the distance B between the air outlet 43 and the inner liner 2 is greater than 5 mm, which ensures smooth flow of air and reduces wind resistance.

[0060] As a preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the insulation ring 4 is provided with an air outlet 43 communicating with the second cooling cavity 12 and the outside of the insulation ring 4 , and a wind shielding rib 41 is provided between the communication port 51 and the air outlet 43 .

[0061] After the airflow in the first cooling chamber 11 enters the second cooling chamber 12 through the connecting port 51, it cannot flow directly to the air outlet 43 due to the obstruction of the wind shielding ribs 41, and can only flow along the extension direction of the wind shielding ribs 41, which helps to flow horizontally in the second cooling chamber 12 to form a spiral airflow surrounding the inner liner 2, thereby extending the time of the airflow in the second cooling chamber 12 and the contact time with the inner liner 2, thereby improving the air cooling effect.

[0062] Furthermore, if Figure 4 As shown, the air outlet 43 is located above the connecting port 51 , the wind shielding rib 41 is located between the connecting port 51 and the air outlet 43 , and the wind shielding rib 41 has flow channels 411 at both ends along the circumferential direction of the insulation ring 4 .

[0063] The windshield rib 41 extends along the circumference of the insulation ring 4. The windflow in the first cooling chamber 11 flows upward from the connecting port 51 into the second cooling chamber 12, is blocked by the windshield rib 41, and then flows toward the two ends of the windshield rib 41 in the extension direction of the windshield rib 41, thereby surrounding the outer periphery of the inner liner 2, and finally flows upward over the end of the windshield rib 41, and further flows from the end of the windshield rib 41 to the middle under the guidance of the windshield rib 41, and finally flows out from the air outlet 43.

[0064] Optional, such as Figure 4 As shown, the partition 5 has a raised section 52 , and a flow passage 411 is formed between the end of the wind shielding rib 41 and the raised section 52 .

[0065] Preferably, the partition 5 has a connecting area along the circumferential direction, wherein one connecting port 51 may be provided in the connecting area, or multiple connecting ports 51 may be provided at intervals. The side wall 23 of the insulation ring 4 has an air outlet area, wherein one air outlet 43 may be provided in the air outlet area, or multiple air outlets 43 may be provided at intervals. The length of the wind shield rib 41 along the circumferential direction of the insulation ring 4 is greater than the connecting area and the air outlet area, so that the airflow entering the second cooling chamber 12 at the connecting port 51 first flows from the lower side of the wind shield rib 41 to the two ends of the wind shield rib 41, and then flows from the upper side of the wind shield rib 41 to the middle of the wind shield rib 41, thereby extending the flow path and improving the cooling effect.

[0066] In a preferred embodiment, Figure 2 , Figure 6 As shown, the region of the inner liner 2 and / or the insulation ring 4 corresponding to the second cooling chamber 12 has a curved portion 42 that is concave toward a direction away from the second cooling chamber 12 .

[0067] The setting of the curved portion 42 can widen the width of the second cooling chamber 12, reduce the flow resistance of the airflow in the second cooling chamber 12, enable the airflow to flow more smoothly in the second cooling chamber 12, and enable the airflow to have better and more complete contact with the inner liner 2 in the second cooling chamber 12, thereby improving the air cooling effect.

[0068] Preferably, if Figure 6 As shown, the curved portion 42 is provided on the heat preservation ring 4 and is recessed outward, which improves versatility and does not require structural modification of the inner liner 2. It can play a corresponding role when used with different types of inner liner 2. Of course, the curved portion 42 can also be provided on the side wall 23 of the inner liner 2, or both the inner liner 2 and the heat preservation ring 4 are provided with the curved portion 42, that is, the side wall 23 of the inner liner 2 is recessed inward, and the corresponding position of the heat preservation ring 4 is recessed outward, further increasing the flow diameter of the second cooling chamber 12.

[0069] It should be noted that the present invention does not limit the number and location of the cooling fans 3. In one embodiment, Figure 1 , Figure 7 As shown, there are two cooling fans 3 which are arranged on both sides of the heat preservation ring 4 in the radial direction of the pot body 1 , and the connecting port 51 and the cooling fans 3 are arranged in a staggered manner.

[0070] The cold air enters the first cooling chamber 11 from both sides, cools the bottom of the inner tank 2, flows to both sides and upwards, and enters the second cooling chamber 12 from the connecting openings 51 on both sides. Specifically, there are two connecting openings 51, and the connecting line of the two connecting openings 51 is perpendicular to the connecting line of the two fans.

[0071] Furthermore, in order to prevent the two cooling fans 3 from blowing air in opposite directions and causing the two air flows to collide and form turbulence, a partition can be provided below the inner tank 2 to divide the first cooling chamber 11 into a first chamber and a second chamber, and a portion of the air outlet of each cooling fan 3 is located in the first chamber and a portion of the air outlet is located in the second chamber. Alternatively, the air outlet of one cooling fan 3 is completely located in the first chamber, and the air outlet of the other cooling fan 3 is completely located in the second chamber, and this is not limited.

[0072] In another embodiment, there are more than two cooling fans 3 , which are evenly spaced apart along the circumference of the thermal insulation ring 4 , and the connecting port 51 is located between two adjacent cooling fans 3 .

[0073] In another embodiment, the insulation ring 4 has an air inlet side and a communication side that are arranged opposite to each other, there is at least one cooling fan 3 and it is disposed on the air inlet side, and the communication port 51 is located on the communication side.

[0074] When there is only one cooling fan 3, it can be arranged on the air inlet side of the insulation ring 4, and the connecting port 51 is set on the connecting side opposite to the air inlet side to extend the flow path of the airflow in the first cooling cavity 11 and increase the contact time of the bottom of the airflow domain inner liner 2.

[0075] When there are more than one cooling fan 3 , all cooling fans 3 may be arranged on the air inlet side, and a connecting port 51 is provided on the opposite connecting side. Preferably, when there is one connecting port 51 , it is located on the central axis of the fan group composed of the cooling fans 3 .

[0076] As a preferred embodiment of the present invention, Figure 1 As shown, the pot body 1 also includes an electromagnetic wire coil 6 arranged below the inner pot 2, the inner pot 2 includes a bottom wall 21, a side wall 23 and a transition section 22 located between the bottom wall 21 and the side wall 23, the first cooling chamber 11 includes a first gap 111 between the transition section 22 and the electromagnetic wire coil 6, and a second gap 112 between the bottom wall 21 and the electromagnetic wire coil 6, and the first gap 111 is smaller than the second gap 112.

[0077] After the air-cooling airflow enters the first cooling cavity 11, it flows downward along the interior of the inner liner 2 and passes through the first gap 111 and the second gap 112 in sequence. The flow diameter of the first gap 111 is smaller than that of the second gap 112, and the flow speed of the airflow in the first gap 111 is faster, thereby accelerating the airflow and allowing the air-cooling airflow to enter the second gap 112 at a faster speed. The flow diameter of the second gap 112 is larger, and after the airflow enters at a faster flow rate, it will quickly diffuse in the second gap 112 and flow horizontally under the guidance of the bottom of the inner liner 2, thereby causing part of the airflow to flow from the bottom of the inner liner 2, fully contacting the bottom of the inner liner 2, and taking away the heat from the bottom of the inner liner 2, while part of the airflow flows in the circumferential direction of the inner liner 2, thereby forming a cooling ring at the bottom of the inner liner 2, and rapidly cooling the bottom of the inner liner 2.

[0078] Of course, the utility model does not limit the type of heating device of the cooking utensil. The heating device can be not only the electromagnetic wire coil 6 mentioned above, but also a heating plate, so as to heat the inner pot 2 by heat transfer through contact with the inner pot 2. At this time, there is no gap between the bottom wall 21 of the inner pot 2 and the heating plate, and the air-cooled airflow entering the first cooling cavity 11 can also dissipate the heat from the heating plate, thereby reducing the heat transferred from the heating plate to the inner pot 2 and improving the cooling efficiency of the bottom of the inner pot 2.
