Description

TECHNICAL FIELD

[0001] The present application relates to the field of small household appliances, in particular to a cooking appliance. BACKGROUND

[0002] At present, the pressure cooking appliance uses the principle that the increase of air pressure increases the boiling point of liquid to make the water in the cooking cavity reach a higher temperature without boiling, so as to speed up the cooking efficiency of food.

[0003] In order to ensure that the cooking appliance can be normally pressed, the related technology generally sets a cover tooth on the cover body and sets a pot tooth on the appliance body, the cover body has a locking position, when the cover body is located at the locking position, the pot tooth and the cover tooth can be completely locked, at this time, the amount of the teeth of the pot tooth and the cover tooth reaches the maximum, so as to ensure that when the air pressure in the cooking appliance increases, the cover body will not be separated from the cooking appliance.

[0004] However, when the cooking appliance is locked by using the above-mentioned method, the user cannot judge whether the cover body has been accurately rotated to the locking position, if the user does not rotate the cover body to the position, the amount of the teeth of the pot tooth and the cover tooth will be small, when the air pressure in the cooking appliance increases, the pressure cooker will have the risk of explosion, which leads to poor safety of the cooking appliance. SUMMARY

[0005] The main purpose of the present application is to provide a cooking appliance to solve the problem of poor safety of the cooking appliance in the related technology.

[0006] In order to achieve the above-mentioned purpose, the present application provides a cooking appliance, comprising: an appliance body having a cooking cavity; a cover body covered on the appliance body, the cover body comprising a locking position locked on the appliance body and a non-locking position not locked on the appliance body, the cover body being provided with an exhaust passage communicated with the cooking cavity; a handle provided on the cover body, the handle driving the cover body to rotate between the locking position and the non-locking position; a pressure limiting valve blocking the exhaust port of the exhaust passage when the cover body is located at the locking position; a driving structure driving the pressure limiting valve away from the exhaust port when the cover body is located at the non-locking position.

[0007] When the cover body is located at the non-locked position, the driving structure can drive the pressure-limiting valve to be away from the exhaust port of the exhaust passage, at this time, the cooking cavity in the cooking utensil is communicated with the outside atmosphere through the exhaust passage, even if the cooking utensil is in the heating state, the hot gas generated in the cooking cavity can be discharged through the exhaust passage, thereby avoiding the phenomenon of the cooking utensil exploding, and the safety of the cooking utensil is improved. When the cover body is rotated to the locked position, the driving structure can be away from the pressure-limiting valve, at this time, the pressure-limiting valve blocks the exhaust passage, so that the cooking utensil can be normally pressurized. Since the cover body is located at the locked position, the cover tooth on the cover body and the pot tooth on the utensil body can be completely locked, and the amount of the buckle tooth between the cover tooth and the pot tooth reaches the maximum, so that the increase of the pressure in the cooking utensil will not be dangerous. The above structure can avoid the phenomenon of the cooking utensil exploding due to the cover body and the utensil body not being locked in place, thereby improving the safety of the cooking utensil.

[0008] Further, the driving structure comprises a lever and a pushing structure matched with each other, the lever is pivotally arranged on the cover body, the first end of the lever is located below the pressure-limiting valve, the pushing structure is arranged on the utensil body, in the case that the cover body is located at the locked position, the pushing structure is matched with the second end of the lever, the second end of the lever is lifted, the first end of the lever is sunk and away from the pressure-limiting valve, and the pressure-limiting valve is blocked at the exhaust port, in the case that the cover body is located at the non-locked position, the pushing structure is dislocated with the second end of the lever, and the lever pushes the pressure-limiting valve away from the exhaust port. In the above structure, when the cover body is located at the non-locked position, the first end of the lever can push the pressure-limiting valve, so that the cooking cavity is communicated with the outside atmosphere, thereby ensuring that the cooking utensil will not be pressurized when the cover body is located at the non-locked position, thereby avoiding the danger of the cooking utensil exploding. When the cover body is located at the locked position, the pushing structure pushes the second end of the lever upward, so that the first end of the lever is away from the pressure-limiting valve, at this time, the pressure-limiting valve can block the exhaust port of the exhaust passage, thereby enabling the cooking utensil to be normally pressurized, and meeting the pressure cooking demand of the user.

[0009] Further, the pushing structure is an upward protruding protrusion; in the structure, when the cover rotates from the non-locking position to the locking position, the protrusion can push the second end of the lever upward, so that the first end of the lever falls away from the pressure limiting valve. The pressure limiting valve can block the exhaust port of the exhaust passage, and the cooking appliance can normally pressurize. The structure is simple, and it is not necessary to set a driving component, and the lifting and falling of the pressure limiting valve can be realized by opening and closing the cover, thereby reducing the production cost. In addition, the structure is convenient for processing the pushing structure. Alternatively, the second end of the lever is provided with a first magnetic block, and the pushing structure includes a second magnetic block, and the magnetic pole of the first magnetic block close to the second magnetic block is the same as the magnetic pole of the second magnetic block close to the first magnetic block. In the structure, the first magnetic block can move upward under the repulsion of the second magnetic block, thereby driving the second end of the lever to move upward, so that the first end of the lever falls away from the pressure limiting valve. The pressure limiting valve can block the exhaust port of the exhaust passage, and the cooking appliance can normally pressurize. The structure can also achieve the effect of pushing the lever.

[0010] Further, the pushing structure is an upward protruding protrusion, and the cover is provided with a movable top column, the top column is located below the second end of the lever, and the protrusion drives the lever to rotate through the top column. In the structure, the pushing structure drives the second end of the lever to move upward by pushing the top column, reduces the length of the lever from the pivot shaft to the second end of the lever, and reduces the required movement space of the lever, thereby facilitating the miniaturization design of the cooking appliance.

[0011] Further, the lower surface of the top column matched with the protrusion includes an inclined surface, and / or the upper surface of the protrusion matched with the top column includes an inclined surface, and the inclined surface gradually inclines upward in the locking direction n of the cover. In the structure, the inclined surface can make the cover smoothly transition during the rotation to the locking position, thereby improving the user experience.

[0012] Further, the cover is provided with a fixing seat, and the top column is movably arranged on the fixing seat. In the structure, the fixing seat can fix the top column, thereby facilitating the pushing of the lever by the top column.

[0013] Further, the cover includes a cover body and a connecting arm arranged on the cover body, the cover body is provided with a mounting gap at the position corresponding to the connecting arm at the bottom edge of the cover body, and the fixing seat is arranged at the mounting gap and extends into the connecting arm. In the structure, the fixing seat extends outward from the mounting gap, i.e. horizontally mounted. The structure fully utilizes the space of the cover in the radial direction, thereby reducing the thickness of the cover and realizing the miniaturization design of the cooking appliance.

[0014] Further, the fixing base comprises a bottom wall, a part of the top column below the bottom wall is matched with the protrusion, the bottom of the connecting arm is provided with a first avoiding recess, the first avoiding recess is located at the front side of the top column in the locking direction n of the cover body, and the upper surface of the first avoiding recess is flush with the lower surface of the bottom wall of the fixing base. In the above structure, when the cover body rotates towards the locking direction n, the first avoiding recess can avoid the pushing structure, and with the continuous rotation of the cover body, the pushing structure can abut against the inclined surface of the top column to push the top column upward. The upper surface of the first avoiding recess is flush with the lower surface of the bottom wall of the fixing base, so that the step surface can be reduced, and cleaning is facilitated.

[0015] Further, the first elastic structure or the first magnetic structure is arranged between the cover body and the upper surface of the second end of the lever, and the lever drives the pressure limiting valve to move away from the exhaust port under the elastic force of the first elastic structure or the repulsive force of the first magnetic structure. In the above structure, the first elastic structure enables the lever to maintain the pushing state of the pressure limiting valve when the cover body is in the non-locking position. In addition, when the cover body moves from the locking position to the non-locking position, the first elastic structure also enables the top column to automatically return to the sunken position, thereby facilitating the use experience of the user. Alternatively, the second elastic structure or the second magnetic structure is arranged between the cover body and the lower surface of the first end of the lever, and the lever drives the pressure limiting valve to move away from the exhaust port under the elastic force of the second elastic structure or the repulsive force of the second magnetic structure. The above structure also has the effect of maintaining the lever in the pushing state of the pressure limiting valve. Alternatively, the gravity moment of the second end of the lever is greater than the sum of the gravity moment of the first end of the lever and the moment generated by the pressure limiting valve at the first end of the lever.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 7 As shown, the cooking appliance of this application includes: an appliance body 10, a lid 20, a handle, a pressure relief valve 30, and a drive structure 40. The appliance body 10 has a cooking cavity 1; the lid 20 is placed on the appliance body 10, and the lid 20 includes a locked position that is locked onto the appliance body 10 and a unlocked position that is not locked onto the appliance body 10. The lid 20 is provided with an exhaust channel 2 communicating with the cooking cavity 1; the handle is provided on the lid 20, and the handle drives the lid 20 to rotate between the locked position and the unlocked position; the pressure relief valve 30 blocks the exhaust port of the exhaust channel 2 when the lid 20 is in the locked position; the drive structure 40 drives the pressure relief valve 30 away from the exhaust port when the lid 20 is in the unlocked position.

[0034] Applying the technical solution of this embodiment, when the lid 20 is in the non-locked position, the drive structure 40 can drive the pressure relief valve 30 away from the exhaust port of the exhaust channel 2. At this time, the cooking chamber 1 inside the cooking appliance is connected to the outside atmosphere through the exhaust channel 2. Even if the cooking appliance is in a heating state, the hot air generated in the cooking chamber 1 can be discharged through the exhaust channel 2, thereby avoiding the phenomenon of the cooking appliance splattering and improving the safety of the cooking appliance. When the lid 20 is rotated to the locked position, the drive structure 40 can move away from the pressure relief valve 30. At this time, the pressure relief valve 30 blocks the exhaust channel 2, allowing the cooking appliance to pressurize normally. Since when the lid 20 is in the locked position, the lid teeth 232 on the lid 20 and the pot teeth 11 on the appliance body 10 can be fully locked, and the amount of interlocking teeth between the lid teeth 232 and the pot teeth 11 reaches its maximum, so even if the pressure inside the cooking appliance increases, no danger will occur. The above structure, by setting the drive structure 40, can avoid the phenomenon of frying caused by the lid 20 not locking properly with the utensil body 10, thereby improving the safety of the cooking utensil.

[0035] like Figure 4 and Figure 7As shown in the drawings, in the embodiment, the driving structure 40 comprises a lever 50 and a pushing structure 60, the lever 50 is pivotally arranged on the cover 20, a first end 51 of the lever 50 is below the pressure-limiting valve 30, the pushing structure 60 is arranged on the appliance body 10, when the cover 20 is in the locked position, the pushing structure 60 cooperates with a second end 52 of the lever 50, the second end 52 of the lever 50 is lifted, the first end 51 of the lever 50 is lowered and away from the pressure-limiting valve 30, the pressure-limiting valve is blocked at the exhaust port, when the cover 20 is in the unlocked position, the pushing structure 60 is misaligned with the second end 52 of the lever 50, the lever 50 pushes the pressure-limiting valve 30 away from the exhaust port. In the above structure, when the cover is in the unlocked position, the first end 51 of the lever 50 can push the pressure-limiting valve 30, so that the cooking cavity 1 is connected with the outside atmosphere, thereby ensuring that the cooking appliance does not overpressure when the cover 20 is in the unlocked position, thereby avoiding the risk of the cooking appliance exploding. When the cover is in the locked position, the pushing structure 60 pushes the second end 52 of the lever 50 upward, so that the first end 51 of the lever 50 is away from the pressure-limiting valve 30, at this time, the pressure-limiting valve 30 can block the exhaust port of the exhaust passage 2, so that the cooking appliance can normally overpressure, meeting the user's pressure cooking demand.

[0036] As shown in the drawings, Figure 1 , Figure 2 and Figure 7 , in the embodiment, the pushing structure 60 is a protruding convex. In the above structure, when the cover rotates from the unlocked position to the locked position, the convex can push the second end 52 of the lever 50 upward, so that the first end 51 of the lever 50 falls away from the pressure-limiting valve 30. The pressure-limiting valve 30 can block the exhaust port of the exhaust passage 2, so that the cooking appliance can normally overpressure. The above structure is simple, without the need to set driving components, the lifting and falling of the pressure-limiting valve 30 can be realized by opening and closing the cover, thereby reducing production cost. In addition, the above structure is convenient for processing the pushing structure 60.

[0037] In other embodiments not shown in the drawings, a first magnetic block can also be arranged on the second end 52 of the lever 50, the pushing structure 60 comprises a second magnetic block, the magnetic pole of the first magnetic block close to the second magnetic block is the same as the magnetic pole of the second magnetic block close to the first magnetic block. In the above structure, the first magnetic block can move upward under the repulsion of the second magnetic block, thereby driving the second end of the lever 50 to move upward, so that the first end 51 of the lever 50 falls away from the pressure-limiting valve 30. The pressure-limiting valve 30 can block the exhaust port of the exhaust passage 2, so that the cooking appliance can normally overpressure. The above structure can also achieve the effect of pushing the lever 50.

[0038] Directly pushing the lever 50 by the pushing structure 60 requires that the length of the lever 50 from the pivot shaft to the second end 52 of the lever 50 is long, so the pushing structure 60 needs to push the second end 52 of the lever 50 upward by a long distance, and the first end of the lever 50 can be smoothly separated from the pressure limiting valve 30. This way requires a large space for the lever 50 to move, which is not conducive to the miniaturization design of the cover. To solve the above problems, as shown in Figure 4 、 Figure 7 、 Figures 10 to 12 In the present embodiment, a movable top pillar 70 is arranged on the cover 20, the top pillar 70 is located below the second end 52 of the lever 50, and the convex is used to drive the lever 50 to rotate. In the above structure, the pushing structure 60 drives the second end of the lever 50 to move upward by pushing the top pillar 70, which reduces the length of the lever 50 from the pivot shaft to the second end 52 of the lever 50, and reduces the space required for the lever 50 to move, thereby facilitating the miniaturization design of the cooking appliance.

[0039] As shown in Figure 5 、 Figures 8 to 12 In the present embodiment, the lower surface of the top pillar 70 includes a slope that abuts against the convex, and the slope gradually inclines upward in the locking direction n of the cover 20. In the above structure, when the cover 20 rotates towards the locking direction n, the pushing structure 60 will abut against the slope of the top pillar 70, and the top pillar 70 will move upward under the action of the slope, thereby pushing the second end of the lever 50 upward. The above structure can make the cover 20 smoothly transition during the rotation to the locked position, thereby improving the user's experience.

[0040] It should be noted that in other embodiments not shown in the figure, the upper surface of the convex can be a slope that is adapted (same inclination angle) to the slope of the top pillar. The above structure can also achieve the purpose of smooth transition of the cover during rotation to the locked position. In addition, in another embodiment not shown in the figure, the lower surface of the top pillar that abuts against the convex and the upper surface of the convex that abuts against the top pillar can both be slopes. The above structure makes the cover more smooth when locked, improving the user's experience.

[0041] As shown in Figure 4 and Figure 7As shown, in the embodiment, the cover 20 is provided with a fixing seat 80, and the top column 70 is movably arranged on the fixing seat 80. In the above structure, the top column 70 has a floating position and a sinking position. When the cover 20 is in the non-locking position, the top column is in the sinking position, so that the first end 51 of the lever 50 is lifted upward, thereby driving the pressure limiting valve 30 to be lifted. When the cover 20 is in the locking position, the top pushing structure 60 pushes the top column 70 to the floating position, and the top column 70 drives the first end 51 of the lever 50 to be away from the pressure limiting valve 30, so that the pressure limiting valve 30 blocks the exhaust passage 2, and the cooking utensil can be normally pressurized. The above structure can fix the top column 70 through the fixing seat 80, thereby facilitating the top column 70 to push the lever 50.

[0042] It should be noted that, as shown in Figure 11 and Figure 12 , the top column 70 comprises a matching part 71 and a top pushing part 72 arranged above the matching part 71, the lower surface of the matching part 71 is formed as an inclined surface, and the top pushing part 72 directly contacts the lever 50 to push the lever 50. The matching part 71 is provided with a buckle 711 extending upward, the fixing seat 80 is provided with a buckle opening 82, the top column 70 is buckled in the buckle opening 82 of the fixing seat 80 through the buckle 711, and the buckle 711 can move in the buckle opening 82, so that the top column 70 can float in the fixing seat 80.

[0043] As shown in Figure 1 , Figures 8 to 10 , in the embodiment, the cover 20 comprises a cover body 24 and a connecting arm 90 arranged on the cover body 24, the cover body 24 is provided with a mounting gap 21 at the position corresponding to the connecting arm 90 at the bottom edge, and the fixing seat 80 is arranged at the mounting gap 21 and extends into the connecting arm 90. In the above structure, the fixing seat 80 extends outward from the mounting gap 21, that is, it is horizontally mounted. The above structure fully utilizes the space of the cover 20 in the radial direction, thereby reducing the thickness of the cover and realizing the miniaturization design of the cooking utensil.

[0044] As shown in Figures 8 to 10 , in the embodiment, the fixing seat 80 comprises a bottom wall 81, the part of the top column 70 below the bottom wall 81 is matched with the protrusion, the bottom of the connecting arm 90 is provided with a first avoiding recess 91, the first avoiding recess 91 is located in front of the top column 70 in the locking direction n of the cover 20, and the upper surface of the first avoiding recess 91 is flush with the lower surface of the bottom wall 81 of the fixing seat 80. In the above structure, when the cover 20 rotates towards the locking direction n, the first avoiding recess 91 can avoid the top pushing structure 60, and with the continuous rotation of the cover 20, the top pushing structure 60 can abut against the inclined surface of the top column 70 to push the top column 70 upward. The upper surface of the first avoiding recess 91 is flush with the lower surface of the bottom wall 81 of the fixing seat 80, which can reduce the step surface and facilitate cleaning.

[0045] It should be noted that the fixed seat 80 further comprises a limiting plate 83, which is located at the rear side of the top post 70 in the locking direction n of the cover body 20. When the cover body 20 is rotated to the locked position, if the cover body 20 is continuously rotated in the locking direction n, the pushing structure 60 on the appliance body 10 will form a stop to the limiting plate 83, so that the user cannot continue to rotate the cover body 20 in the locking direction n, thereby prompting the user that the cover body 20 has been rotated to the locked position.

[0046] As shown in FIGS. Figure 4 , Figure 7 , Figure 11 and Figure 12 , in the present embodiment, a first elastic structure 100 is arranged between the cover body 20 and the upper surface of the second end 52 of the lever 50, and the lever 50 drives the pressure limiting valve 30 to move away from the exhaust port under the elastic force of the first elastic structure 100. In the above structure, the cover body 20 is provided with a guide column 221, and the first elastic structure 100 is a spring which is sleeved on the circumferential outer side of the guide column 221, and the guide column 221 can make the spring move in the vertical direction. The first elastic structure 100 is located between the cover body 20 and the second end 52 of the lever 50, and the first elastic structure 100 pushes the second end 52 of the lever 50 downward by the elastic restoring force of itself, so that the first end 51 of the lever 50 remains in the pushing state to the pressure limiting valve 30. When the cover body 20 is in the locked position, the pushing structure 60 drives the top post 70 to push the second end 52 of the lever 50 upward, and at this time, the pushing force of the pushing structure 60 is greater than the elastic restoring force generated by the first elastic structure 100, so that the second end 52 of the lever 50 moves upward, drives the first end 51 of the lever 50 to move away from the pressure limiting valve 30, and the pressure limiting valve 30 can fall by its own gravity to block the exhaust port of the exhaust passage 2, so that the cooking appliance can normally press. When the cover body 20 is in the unlocked position, the lever 50 can remain in the pushing state to the pressure limiting valve 30. In addition, when the cover body 20 moves from the locked position to the unlocked position, the first elastic structure 100 can also make the top post 70 automatically return to the sunken position, thereby facilitating the user's experience. Of course, in other embodiments not shown in the figure, a first magnetic structure can also be arranged between the cover body 20 and the upper surface of the second end 52 of the lever 50, and the first magnetic structure repels the cover body and the second end 52 of the lever 50 to move away from each other, so that the first end 51 of the lever 50 remains in the pushing state to the pressure limiting valve 30. In other embodiments not shown in the figure, a second elastic structure or a second magnetic structure can be arranged between the cover body 20 and the lower surface of the first end 51 of the lever 50, and the lever 50 drives the pressure limiting valve 30 to move away from the exhaust port under the elastic force of the second elastic structure or the repulsion of the second magnetic structure. The above structure can also have the effect of keeping the lever 50 in the pushing state to the pressure limiting valve 30.

[0047] In other embodiments not shown in the drawings, the gravity moment of the second end 52 of the lever 50 can also be made greater than the sum of the gravity moment of the first end 51 of the lever 50 and the moment of force generated by the pressure-limiting valve 30 at the first end 51 of the lever 50. The above structure can rely on the self-gravity of the second end 52 of the lever 50 to keep the lever 50 in the state of pushing the pressure-limiting valve 30. The above structure is simple and facilitates production and processing.
