Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, in particular to a cover assembly and a cooking utensil having the same. Background Art

[0002] In the related art, multifunctional cooking appliances integrate multiple cooking functions and are increasingly popular among consumers. Since different cooking functions require different pressures, it is necessary to make the cooking appliances have different pressure modes.

[0003] For example, in the related art, there is a cooking appliance capable of multi-speed pressure regulation, in which a driving member moves along a predetermined trajectory to drive a pressure limiting valve to switch states. However, when a user operates the driving member by himself, it is easy to be misaligned, causing the driving member to move to a position adjacent to the preset pressure level, affecting the user's experience. Utility Model Content

[0004] The main purpose of the utility model is to provide a cover assembly and a cooking utensil having the same, so as to solve the problem in the related art that misalignment easily occurs when a user operates a driving member by himself.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a cover body assembly is provided, including: a cover body; an exhaust pipe, which is inserted into the cover body and has an exhaust passage; a pressure limiting valve, which is sleeved on the upper end of the exhaust pipe, and the pressure limiting valve is movably arranged on the cover body along the vertical direction and has a plurality of working positions; a driving member, which is movably arranged on the cover body and has a plurality of driving positions, and the driving member can drive the pressure limiting valve to different working positions when it is in different driving positions; a positioning structure, including a first magnetic member arranged on the driving member and a second magnetic member arranged on the cover body, and the first magnetic member and the second magnetic member can cooperate with each other by magnetic attraction so that the driving member remains in one of the driving positions.

[0006] By applying the technical solution of the utility model, the pressure limiting valve is arranged above the exhaust pipe, and the pressure in the cooking cavity needs to be large enough to overcome the gravity of the pressure limiting valve to open the pressure limiting valve to exhaust the air, thereby realizing the limitation of the maximum pressure in the cooking cavity. The pressure limiting valve has multiple working positions. When the pressure limiting valve is in different working positions, the pressure of the pressure limiting valve on the exhaust pipe is different, and the pressure required to open the pressure limiting valve is also different, thereby realizing multi-level pressure regulation. The driving member is movably arranged on the cover body, and the user can drive the pressure limiting valve to switch the working state by operating the driving member. The cover body assembly also includes a positioning structure, which includes a first magnetic member and a second magnetic member that are magnetically matched. When the user operates the driving member to the vicinity of the corresponding position, the first magnetic member enters the magnetic force range of the second magnetic member. Since the second magnetic member will absorb the first magnetic member, the first magnetic member drives the driving member to move to a suitable position, thereby realizing the automatic and accurate positioning of the driving member when it reaches the vicinity of the target driving position. Therefore, the technical solution of the present application can effectively solve the problem in the related art that misalignment easily occurs when users operate the driving member by themselves.

[0007] Furthermore, the driving member includes a turntable sleeved on the outer periphery of the pressure limiting valve and an extension rod connected to the turntable, and the first magnetic member is arranged at an end of the extension rod away from the turntable.

[0008] Furthermore, the cover body is provided with a through hole, and the pressure-limiting valve and the turntable are upwardly extended out of the through hole, wherein the extension rod is located below the cover body, and the second magnetic attraction member is arranged on the surface of the cover body facing the extension rod; and / or, the cover body assembly further comprises an indication structure, the indication structure comprises an indication part and a plurality of identification parts, the indication part is arranged on one of the cover body and the turntable, and the plurality of identification parts are arranged on the other of the cover body and the turntable, and when the pressure-limiting valve is located at different working positions, the indication part is arranged corresponding to different identification parts. The pressure-limiting valve and the turntable are upwardly extended out of the through hole, which is convenient for exhaust and for the user to adjust the working position of the pressure-limiting valve through the turntable. The arrangement of the identification part and the indication part makes it convenient for the user to observe the position of the turntable and facilitates the user's use.

[0009] Furthermore, a first guide groove is provided on the cover body, and the extension rod includes a first rod segment and a second rod segment extending in the same direction, the first end of the first rod segment is connected to the turntable, the first end of the second rod segment is slidably connected to the second end of the first rod segment, and the second end of the second rod segment is provided with a first slider that can cooperate with the first guide groove. The outer contour of the cover assembly is a non-circular structure and the pressure limiting valve is not arranged in the middle of the cover assembly. The extension rod is arranged as a split structure that cooperates with the sliding, so that the path of the second end of the extension rod can be as close to the edge of the cover body as possible so that the total length of the extension rod is as long as possible.

[0010] Furthermore, the driving member includes a rotating disk sleeved on the outer periphery of the pressure limiting valve, and the first magnetic member is arranged on the rotating disk. In this way, there is no need to arrange an additional extension rod, which simplifies the arrangement of the first magnetic member and the second magnetic member.

[0011] Furthermore, the cover assembly also includes a guide structure, which includes a second guide groove and a second slider, one of which is arranged on the cover body, and the other of which is arranged on the driving member; the second guide groove has a plurality of support sections and at least one inclined section, and the plurality of support sections are arranged at intervals in the axial direction and the circumferential direction of the pressure limiting valve, and each two adjacent support sections are connected by an inclined section, and when the driving member rotates, the second slider slides in the second guide groove so that the driving member moves in the vertical direction, and when the second slider is located in different support sections, the driving member is located in different driving positions. The user drives the driving member to rotate and move up or down at the same time by turning the turntable, thereby driving the pressure limiting valve to switch the position state, which has the advantages of simple structure and no need to set up a complex electrical control structure.

[0012] Furthermore, the plurality of support sections include a high-pressure support section, a low-pressure support section and a pressure-free support section which are sequentially arranged along the circumferential direction of the pressure-limiting valve, and the heights of the high-pressure support section, the low-pressure support section and the pressure-free support section gradually increase, and the first magnetic member and the second magnetic member can keep the driving member in a position that cooperates with the low-pressure support section when magnetically engaged. The alignment structure is only arranged at the low-pressure support section which is easily misaligned by the user, thereby reducing the number of alignment structures and reducing the manufacturing cost of the cover assembly.

[0038] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the present application provides a cover assembly, and an embodiment of the cover assembly of the present application includes: a cover 10, an exhaust pipe 20, a pressure limiting valve 30, a driving member 40 and a positioning structure 50. Among them, the exhaust pipe 20 is arranged in the cover 10 and has an exhaust channel 21; the pressure limiting valve 30 is sleeved on the upper end of the exhaust pipe 20, and the pressure limiting valve 30 is movably arranged on the cover 10 along the vertical direction and has a plurality of working positions; the driving member 40 is movably arranged on the cover 10 and has a plurality of driving positions, and the driving member 40 can drive the pressure limiting valve 30 to different working positions when it is in different driving positions; the positioning structure 50 includes a first magnetic member 51 arranged on the driving member 40 and a second magnetic member 52 arranged on the cover 10, and the first magnetic member 51 and the second magnetic member 52 can cooperate with each other by magnetic attraction so that the driving member 40 is kept in one of the driving positions.

[0039] By applying the technical solution of this embodiment, the pressure limiting valve 30 is arranged above the exhaust pipe 20. The pressure in the cooking cavity needs to be large enough to overcome the gravity of the pressure limiting valve 30 so that the pressure limiting valve 30 can be pushed open to exhaust the gas, thereby limiting the maximum pressure in the cooking cavity. The pressure limiting valve 30 has multiple working positions. When the pressure limiting valve 30 is in different working positions, the pressure of the pressure limiting valve 30 on the exhaust pipe 20 is different, and the pressure required to push the pressure limiting valve 30 open is also different, thereby achieving multi-level pressure regulation. The driving member 40 is movably arranged on the cover body, and the user can drive the pressure limiting valve 30 to switch the working state by operating the driving member 40. The cover assembly also includes a positioning structure 50, which includes a first magnetic member 51 and a second magnetic member 52 that are magnetically matched. When the user operates the driving member to the vicinity of the corresponding position, the first magnetic member 51 enters the magnetic force range of the second magnetic member 52. Since the second magnetic member 52 will absorb the first magnetic member 51, the first magnetic member 51 drives the driving member 40 to move to a suitable position, thereby achieving automatic and accurate positioning of the driving member 40 when it reaches the vicinity of the target driving position. Therefore, the technical solution of this embodiment can effectively solve the problem of inaccurate positioning when the user operates the driving member by himself in the related art.

[0040] It should be noted that, in this embodiment, the first magnetic component 51 and the second magnetic component 52 are both magnets, and the two can attract each other; of course, in other feasible implementations, the first magnetic component 51 and the second magnetic component 52 can be one magnet and the other made of magnetic material (such as iron, cobalt, nickel, etc.).

[0041] like Figure 3 , Figure 4 and Figure 6 As shown, the driving member 40 includes a turntable 41 sleeved on the outer periphery of the pressure limiting valve 30 and an extension rod 42 connected to the turntable 41, and the first magnetic member 51 is arranged at one end of the extension rod 42 away from the turntable 41. In this embodiment, by arranging the extension rod 42 and arranging the first magnetic member 51 at the far end of the extension rod 42, the smaller rotation stroke of the turntable 41 corresponds to the larger swing stroke of the first magnetic member 51, and thus the position accuracy requirements for the arrangement of the first magnetic member 51 and the second magnetic member 52 are relatively low; in addition, the arrangement of the extension rod 42 increases the force arm of the first magnetic member 51 and the second magnetic member 52 for driving the turntable 41 to rotate, so that only a smaller magnetic attraction force is needed to realize automatic and accurate alignment of the turntable 41.

[0042] Specifically, in this embodiment, a connecting hole is provided at the first end of the extension rod 42, a connecting column is provided on the turntable 41, and the extension rod 42 is fixedly connected to the turntable 41 via a fastener passing through the connecting hole and the connecting column.

[0043] like Figures 3 to 6As shown, a through hole 11 is provided on the cover body 10, and the pressure limiting valve 30 and the turntable 41 pass upward through the through hole 11, wherein the extension rod 42 is located below the cover body 10, and the second magnetic member 52 is arranged on the surface of the cover body 10 facing the extension rod 42. The pressure limiting valve 30 and the turntable 41 pass upward through the through hole 11, which is convenient for exhaust and the user to adjust the working position of the pressure limiting valve 30 through the turntable 41. The extension rod 42 is located below the cover body 10, and the cover body 10 can cover the extension rod 42, thereby ensuring the simplicity and beauty of the appearance of the cover assembly. Specifically, in the present embodiment, the cover body 10 includes an outer cover 14, and the outer cover 14 includes a face cover 142 and a liner 143, and the second magnetic member 52 is arranged at the edge of the lower surface of the face cover 142. Of course, in an embodiment not shown in the figure, the second magnetic member can also be arranged on the liner.

[0044] like Figure 1 and Figure 2 As shown, the cover body assembly also includes an indication structure, which includes an indication portion 411 and multiple identification portions 12. The indication portion 411 is arranged on one of the cover body 10 and the turntable 41, and the multiple identification portions 12 are arranged on the other of the cover body 10 and the turntable 41. When the pressure limiting valve 30 is located at different working positions, the indication portion 411 is arranged corresponding to different identification portions 12. Specifically, in the present embodiment, the identification portion 12 is located on the upper surface of the face cover 142, and the indication portion 411 is a raised structure arranged on the outer surface of the turntable 41. The arrangement of the identification portion 12 and the indication portion 411 facilitates the user to observe the position of the turntable 41 and facilitates the user's use.

[0045] like Figure 3 and Figure 4 As shown, a first guide groove 13 is provided on the cover body 10, and the extension rod 42 includes a first rod segment 421 and a second rod segment 422 extending in the same direction, the first end of the first rod segment 421 is connected to the turntable 41, the first end of the second rod segment 422 is slidably connected to the second end of the first rod segment 421, and the second end of the second rod segment 422 is provided with a first sliding block that can cooperate with the first guide groove 13 for guidance. In this embodiment, the outer contour of the cover body assembly is a non-circular structure and the pressure-limiting valve 30 is not arranged in the middle of the cover body assembly. In order to make the path of the second end of the extension rod 42 as close as possible to the edge of the cover body 10 so that the total length of the extension rod 42 is as long as possible, the extension rod 42 is arranged to be a first rod segment 421 and a second rod segment 422 that are separated and can slide together, and a first guide groove 13 is arranged near the edge of the cover body 10, so that the second rod segment 422 can be retracted or moved outward relative to the first rod segment 421 so that the second end of the second rod segment 422 (that is, the second end of the extension rod 42) can always cooperate with the first guide groove 13.

[0046] Specifically, in this embodiment, a guide seat 144 is provided on the liner ring 143 of the outer cover 14 , and the first guide groove 13 is formed on the guide seat 144 .

[0047] like Figures 6 to 8 As shown, the cover body assembly also includes a guide structure 60, which includes a second guide groove 61 and a second slider 62. One of the second guide groove 61 and the second slider 62 is arranged on the cover body 10, and the other of the second guide groove 61 and the second slider 62 is arranged on the driving member 40; the second guide groove 61 has a plurality of support segments 611 and at least one inclined segment 612, and the plurality of support segments 611 are arranged at intervals in the axial direction and the circumferential direction of the pressure limiting valve 30, and each two adjacent support segments 611 are connected by an inclined segment 612. When the driving member 40 rotates, the second slider 62 slides in the second guide groove 61 to make the driving member 40 move in the vertical direction. When the second slider 62 is located at different support segments 611, the driving member 40 is located at different driving positions. Specifically, the second guide groove 61 is an obliquely extended slide groove structure connected in sequence by a support section 611 and an inclined section 612. When the second slider 62 moves to the support section 611, it can stop at this position and make the driving member 40 in a corresponding driving position. In this way, the user can drive the driving member 40 to rotate and move up or down at the same time by rotating the turntable 41, thereby driving the pressure limiting valve 30 to switch the position state. It has the advantages of simple structure and no need to set up a complex electrical control structure.

[0048] Specifically, in this embodiment, the second guide groove 61 is disposed on the cover body 10 , and the second sliding block 62 is disposed on the driving member 40 .

[0049] like Figures 6 to 8As shown, the multiple support segments 611 include a high-pressure support segment 6111, a low-pressure support segment 6112 and a no-pressure support segment 6113 which are sequentially arranged along the circumferential direction of the pressure-limiting valve 30. The heights of the high-pressure support segment 6111, the low-pressure support segment 6112 and the no-pressure support segment 6113 gradually increase. When the first magnetic member 51 and the second magnetic member 52 are magnetically engaged, the driving member 40 can be maintained in a position engaged with the low-pressure support segment 6112. In this embodiment, the second guide groove 61 includes three support sections 611, and correspondingly, the pressure limiting valve 30 also has three working positions. Since the end of the high-pressure support section 6111 away from the low-pressure support section 6112 and the end of the pressure-free support section 6113 away from the low-pressure support section 6112 are both stopped by the end groove wall of the second guide groove 61, when the user needs to rotate the turntable 41 to drive the second slider 62 to move to the high-pressure support section 6111 or the pressure-free support section 6113, it can be determined whether it is rotated to the right position by cooperating with the stopper of the end groove wall. However, when the user needs to rotate the turntable 41 to drive the second slider 62 to move to the low-pressure support section 6112, since the two ends of the low-pressure support section 6112 are respectively connected to an inclined section 612, it is difficult for the user to perceive whether it is rotated to the right position. At this time, the alignment structure 50 helps the user to automatically reach the right position, which is convenient for the user to use. In this embodiment, the alignment structure 50 is provided only in the low-pressure support section 6112 which is easily displaced by the user, thereby reducing the number of the alignment structures 50 and lowering the manufacturing cost of the cover assembly.

[0050] Specifically, in this embodiment, the position of the second magnetic member 52 on the surface cover 142 is determined according to the position of the first magnetic member 51 on the extension rod 42 when the second slider 62 on the driving member 40 rotates to the low-pressure support section 6112.

[0051] Of course, in an embodiment not shown in the figures, a set of alignment structures may also be provided corresponding to each supporting segment.

[0052] like Fig. 9 and Fig.10As shown, the pressure-limiting valve 30 includes an inner valve body 31 and an outer valve body 32 sleeved on the outer periphery of the inner valve body 31, an adjusting groove 311 is provided on the outer surface of the inner valve body 31, and an adjusting protrusion 321 extending into the adjusting groove 311 is provided on the inner surface of the outer valve body 32, the height of the adjusting groove 311 is greater than the height of the adjusting protrusion 321, and the multiple working positions include a high-pressure position, a low-pressure position and a no-pressure position. When the adjusting protrusion 321 is pressed against the lower surface of the adjusting groove 311, the pressure-limiting valve 30 is in the high-pressure position, when the adjusting protrusion 321 is separated from the upper and lower surfaces of the adjusting groove 311, the pressure-limiting valve 30 is in the low-pressure position, and when the adjusting protrusion 321 is pressed against the upper surface of the adjusting groove 311, the pressure-limiting valve 30 is in the no-pressure position, and the driving member 40 drives and cooperates with the outer valve body 32 to switch the pressure-limiting valve 30 between the high-pressure position, the low-pressure position and the no-pressure position. When the adjusting protrusion 321 is pressed against the lower surface of the adjusting groove 311, the weight of the inner valve body 31 and the outer valve body 32 are both pressed on the exhaust pipe 20, and the pressure limiting valve 30 can be pushed open only when the pressure in the cooking chamber is relatively high, thereby realizing high-pressure cooking; when the adjusting protrusion 321 is separated from the upper and lower surfaces of the adjusting groove 311, the outer valve body 32 is supported by the driving member 40, and only the weight of the inner valve body 31 is pressed on the exhaust pipe 20, and the pressure limiting valve 30 can be pushed open only when the pressure in the cooking chamber is relatively low, thereby realizing low-pressure cooking; when the adjusting protrusion 321 is pressed against the upper surface of the adjusting groove 311, the weight of the inner valve body 31 is pressed on the outer valve body 32, and the driving member 40 is supported under the outer valve body 32 and lifts both the inner valve body 31 and the outer valve body 32 so that the upper end of the exhaust pipe 20 is connected to the outside, thereby realizing pressure-free cooking. The above-mentioned pressure regulation is achieved by providing an adjustment groove 311 on the outer surface of the inner valve body 31 and an adjustment protrusion 321 extending into the adjustment groove 311 on the inner surface of the outer valve body 32, which has the advantages of simple structure and easy control.

[0053] It should be noted that the pressure-free cooking in this embodiment is achieved by lifting the pressure-limiting valve 30 vertically as a whole, which is different from using a lever to lift the bottom of one side of the pressure-limiting valve 30. When the pressure-limiting valve 30 is in the above-mentioned pressure-free position, the gas discharged from the exhaust pipe 20 encounters smaller and more balanced resistance, thereby minimizing the pressure difference inside and outside the cooking chamber during pressure-free cooking, which is closer to true pressure-free cooking.

[0054] The number of the marking parts 12 corresponds to the number of the working positions of the pressure limiting valve 30. In this embodiment, there are three marking parts 12, and the markings of "heavy", "light" and "no" are arranged in sequence to correspond to the high pressure position, low pressure position and no pressure position of the pressure limiting valve 30, respectively, so that the user can understand the working position of the pressure limiting valve 30. When the user rotates the dial 41 clockwise so that the indicator part 411 changes from Figure 2When the lowest gear position in the turntable moves upward, when the indicator part 411 rotates to the vicinity of the middle gear position (that is, the identification part 12 marked with the word "light"), the second magnetic attraction part 52 on the cover body 10 and the first magnetic attraction part 51 on the extension rod 42 enter into their respective magnetic force ranges, and the two magnetic attractions attract each other, driving the indicator part 411 on the turntable 41 to align with the middle gear position.

[0055] Specifically, in the present embodiment, the inner valve body 31 comprises a valve body 312 which is separately arranged and a valve cover 313 which is arranged above the valve body 312, the outer edge of the valve cover 313 protrudes outward from the valve body 312, a flange 314 is arranged on the valve body 312, and an adjustment groove 311 is formed between the valve cover 313 and the flange 314; the outer valve body 32 comprises a sleeve 322 and a flange 323 which is arranged above the sleeve 322, the adjustment protrusion 321 is arranged on the sleeve 322, the flange 323 protrudes outward from the sleeve 322, and the turntable 41 is supported below the flange 323 to drive the outer valve body 32 to move in the vertical direction.
