Description

Technical Field

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

[0002] In the related art, the cover body assembly of a pressure cooking appliance generally includes an exhaust structure. The exhaust structure includes an exhaust pipe and a pressure limiting valve arranged above the exhaust pipe. A push - top structure such as a lever cooperating with the pressure limiting valve can lift or lower the pressure limiting valve, thereby realizing the control of the pressure in the cooking cavity or rapid exhaust and pressure reduction after the heating is completed.

[0003] Since the inner cover of the cover body assembly will float upward during the upward pressing process, in order to ensure the relative position relationship between the push - top structure and the pressure limiting valve, the push - top structure is generally arranged on the inner cover. Since the inner cover is a metal cover structure, the push - top structure is generally fixed above the inner cover by welding. Specifically, a fixing seat is connected and fixed above the inner cover, and then the push - top structure is installed on the fixing seat.

[0004] In order to avoid leaving welding marks on the lower surface of the inner cover during the process of welding the fixing seat, a relatively small welding current is generally used for welding operations. However, a small welding current cannot ensure the firmness of welding. In addition, the welding connection method cannot ensure the position accuracy of the fixing seat, thereby causing the push - top structure installed on the fixing seat to be stuck or not pushed in place. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a cover body assembly and a cooking appliance having the same, so as to solve the problem of poor installation position accuracy of the push - top structure in the related art.

[0006] To achieve the above object, according to one aspect of the utility model, a cover body assembly is provided, including: an upper cover; an inner cover arranged below the upper cover; an exhaust structure including an exhaust pipe passing through the inner cover and a valve body arranged above the exhaust pipe. The upper end of the exhaust pipe has an exhaust port. The valve body has a blocking state for blocking the exhaust port and an exhaust state for avoiding the exhaust port; a driving member arranged on the upper cover; a transmission member arranged between the driving member and the exhaust structure. The first end of the transmission member cooperates with the driving member, and the second end of the transmission member cooperates with the valve body. The driving member can cooperate with the first end of the transmission member to drive the transmission member to move, so that the second end of the transmission member drives the valve body to switch from the blocking state to the exhaust state; a mounting seat arranged between the upper cover and the inner cover. The exhaust pipe passes through the mounting seat and fixes the mounting seat on the inner cover. The valve body is located above the mounting seat, and the transmission member is arranged on the mounting seat.

[0007] Applying the technical solution of the present utility model, when exhaust is required, the driving member can drive the transmission member. The transmission member can move under the driving action of the driving member, thereby realizing the pushing of the valve body, so that the valve body switches from the blocking state to the exhaust state to achieve exhaust. The transmission member is installed on the mounting seat, and the mounting seat is installed on the inner cover through the exhaust pipe, which can avoid the position error caused by welding, ensure the relative position relationship between the mounting seat, the exhaust pipe and the valve body, and further ensure the relative position relationship between the transmission member and the valve body, so that the transmission member can smoothly push the valve body and avoid jamming. Therefore, the technical solution of this application can effectively solve the problem of poor installation position accuracy of the pushing structure in the related art.

[0008] Further, the mounting seat has a connecting cylinder, the exhaust pipe passes through the connecting cylinder, and the inner cover supports below the connecting cylinder. By supporting the connecting cylinder with the inner cover, when the inner cover floats up and down, the exhaust structure, the mounting seat and the transmission member arranged on the mounting seat will float up and down together with the inner cover, thereby ensuring the relative position relationship between the transmission member and the valve body.

[0009] Further, the connecting cylinder includes a first cylinder body and a second cylinder body arranged at intervals, the exhaust pipe includes a first pipe body and a second pipe body, the first pipe body passes through the first cylinder body, and the second pipe body passes through the second cylinder body. Such a setting facilitates the positioning between the mounting seat and the inner cover.

[0010] Further, a pressing plate is arranged on the first pipe body, and an end plate is arranged at the lower end of the first cylinder body. The end plate is clamped between the pressing plate and the inner cover. The positioning between the mounting seat and the inner cover is realized by clamping the end plate between the pressing plates, which has the advantages of simple structure and convenient assembly operation.

[0011] Further, the transmission member is a lever structure. The lever structure includes a main body rod, a rotating shaft arranged in the middle of the main body rod, a pushing plate arranged at the first end of the main body rod, and a jack arranged at the second end of the main body rod. The driving member can push the pushing plate to drive the lever structure to swing, and the jack is located below the valve body. Driving the valve body to lift under the drive of the driving member is realized through the swing of the lever structure, which has the advantages of simple structure and easy control.

[0012] Further, the lever structure is arranged below the mounting seat. Among them, an avoidance opening is arranged on the mounting seat, and the jack and at least part of the main body rod are correspondingly arranged with the avoidance opening; and / or, a rotating shaft seat is arranged at the lower part of the mounting seat, a rotating shaft hole is arranged on the rotating shaft seat, and the rotating shaft is rotatably arranged in the rotating shaft hole. The setting of the avoidance opening can avoid the jack and the main body rod, so that the jack can smoothly pass through the mounting seat to abut against the valve body. The cooperation between the rotating shaft and the rotating shaft hole realizes the swingable connection of the transmission member on the mounting seat, which has the advantages of simple structure and reliable connection.

[0013] Further, a first rotating shaft seat and a second rotating shaft seat are spaced apart from each other at the lower part of the mounting seat. A first rotating shaft hole is provided on the first rotating shaft seat, and a second rotating shaft hole is provided on the second rotating shaft seat. The rotating shaft includes a first shaft body and a second shaft body disposed on both sides of the main body rod. The main body rod is located between the first rotating shaft seat and the second rotating shaft seat. The first shaft body is rotatably inserted into the first rotating shaft hole, and the second shaft body is rotatably inserted into the second rotating shaft hole. Wherein, in the up-down direction, the distance between the first rotating shaft seat and the second rotating shaft seat gradually increases; and / or, in the down-up direction, the end face of the first shaft body is inclined towards the second shaft body. Through the above settings, during the process of installing the transmission member onto the mounting seat, it is convenient to perform the alignment operation of the transmission member, and at the same time, the first shaft body and the second shaft body can be guided.

[0014] Further, the mounting seat includes a sealing sheet and a seat body connected below the sealing sheet. The transmission member is disposed below the seat body. The exhaust pipe penetrates through the sealing sheet. The sealing sheet is in sealing cooperation with both the exhaust pipe and the upper cover. The second end of the transmission member can push up at least part of the sealing sheet to drive the valve body to switch from the blocking state to the exhaust state. When the exhaust structure exhausts, the discharged steam, condensed water, etc. are directly discharged to the outside of the cover assembly or remain in the mounting seat, and will not enter between the upper cover and the inner cover.

[0015] Further, the sealing sheet includes a sheet main body, a connecting ring disposed on the outer periphery of the sheet main body, and a corrugated structure connecting the sheet main body and the connecting ring. By providing a corrugated structure between the sheet main body and the connecting ring, the sheet main body can move relative to the connecting ring, that is, when the seat body rotates, the sheet main body moves while the connecting ring remains stationary, taking into account both the lateral rotation ability of the seat body and the sealing ability of the sealing sheet.

[0016] Further, the upper cover includes a face cover, and a steam port is provided on the face cover. The mounting seat further includes an annular pressing plate disposed at the steam port and below the face cover. The edge of the sealing sheet is clamped between the face cover and the annular pressing plate; and / or, the sealing sheet includes a sheet main body, a connecting column disposed below the sheet main body, and a stopper disposed at the lower end of the connecting column. The connecting column penetrates through the seat body, and the stopper is in stop cooperation with the lower surface of the seat body. The annular pressing plate presses below the connecting ring of the sealing sheet, realizing the fixation of the sealing sheet on the face cover, thereby ensuring the installation firmness of the sealing sheet and the sealing performance between the sealing sheet and the face cover.

[0017] According to another aspect of the present invention, there is provided a cooking appliance, including a cover assembly, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem of poor installation position accuracy of the pushing structure in the related art, and the cooking appliance having the above-mentioned cover assembly also has the above-mentioned advantages.

[0038] As Figure 1 and Figure 2 shown, the present application provides a cover assembly. Embodiments of the cover assembly of the present application include: an upper cover 10, an inner cover 20, an exhaust structure 30, a driving member 40, a transmission member 50, and a mounting seat 60. Among them, the inner cover 20 is disposed below the upper cover 10; the exhaust structure 30 includes an exhaust pipe 31 passing through the inner cover 20 and a valve body 32 disposed above the exhaust pipe 31. The upper end of the exhaust pipe 31 has an exhaust port 301, and the valve body 32 has a blocking state for blocking the exhaust port 301 and an exhaust state for avoiding the exhaust port 301; the driving member 40 is disposed on the upper cover 10; the transmission member 50 is disposed between the driving member 40 and the exhaust structure 30. The first end of the transmission member 50 is engaged with the driving member 40, and the second end of the transmission member 50 is engaged with the valve body 32. The driving member 40 can cooperate with the first end of the transmission member 50 to drive the transmission member 50 to move, so that the second end of the transmission member 50 drives the valve body 32 to switch from the blocking state to the exhaust state; the mounting seat 60 is disposed between the upper cover 10 and the inner cover 20. The exhaust pipe 31 passes through the mounting seat 60 and fixes the mounting seat 60 on the inner cover 20. The valve body 32 is located above the mounting seat 60, and the transmission member 50 is disposed on the mounting seat 60.

[0039] Applying the technical solution of this embodiment, when exhaust is required, the driving member 40 can be used to drive the transmission member 50. The transmission member 50 can move under the driving action of the driving member 40, thereby pushing the valve body 32, causing the valve body 32 to switch from the blocking state to the exhaust state and realizing exhaust. The transmission member 50 is installed on the mounting seat 60, and the mounting seat 60 is installed on the inner cover 20 through the exhaust pipe 31, which can avoid the position error caused by welding, ensure the relative position relationship between the mounting seat 60, the exhaust pipe 31 and the valve body 32, and further ensure the relative position relationship between the transmission member 50 and the valve body 32, so that the transmission member 50 can smoothly push the valve body 32 and avoid jamming. Therefore, the technical solution of this embodiment can effectively solve the problem of poor installation position accuracy of the pushing structure in the related art.

[0040] As Figure 1 , Figure 2 and Figure 8 shown, the mounting seat 60 has a connecting cylinder 622, the exhaust pipe 31 passes through the connecting cylinder 622, and the inner cover 20 is supported below the connecting cylinder 622. By supporting the connecting cylinder 622 through the inner cover 20, that is, by supporting the mounting seat 60 through the inner cover 20, when the inner cover 20 floats up and down as the pressure in the cooking cavity rises or falls, the exhaust structure 30, the mounting seat 60 (specifically the seat body 62) and the transmission member 50 provided on the mounting seat 60 will float up and down together with the inner cover 20, thereby ensuring the relative position relationship between the transmission member 50 and the valve body 32.

[0041] As Figure 1 , Figure 2 and Figure 8 shown, the connecting cylinder 622 includes a first cylinder body 6221 and a second cylinder body 6222 arranged at intervals, the exhaust pipe 31 includes a first pipe body 311 and a second pipe body 312, the first pipe body 311 passes through the first cylinder body 6221, and the second pipe body 312 passes through the second cylinder body 6222. That is, in this embodiment, the cover assembly has a double exhaust valve, the first pipe body 311 passes through the inner cover 20 and the first cylinder body 6221, and the second pipe body 312 passes through the inner cover 20 and the second cylinder body 6222, thereby realizing the positioning between the mounting seat 60 and the inner cover 20.

[0042] To further realize the positioning between the inner cover 20 and the mounting seat 60, as Figure 1 , Figure 2 and Figure 8As shown, a pressing plate 313 is provided on the first pipe body 311, and an end plate 6223 is provided at the lower end of the first cylinder body 6221. The end plate 6223 is clamped between the pressing plate 313 and the inner cover 20. Specifically, mounting holes are provided on the end plate 6223, and the size of the mounting holes is adapted to the size of the first pipe body 311. The pressing plate 313 is arranged on the outer side of the first pipe body 311. During installation, the first pipe body 311 passes through the first cylinder body 6221 and the inner cover 20 from top to bottom. The end plate 6223 is clamped between the inner cover 20 and the pressing plate 313 on the first pipe body 311. A connecting nut is provided at the lower end of the first pipe body 311, and the upper surface of the connecting nut abuts against the lower surface of the inner cover 20, thereby realizing the fixation between the mounting seat 60 (specifically the seat body 62) and the inner cover 20. Of course, an end plate is also provided at the lower end of the second cylinder body 6222, and a pressing plate is also provided on the upper part of the second pipe body 312. The connection method between the second cylinder body 6222 and the inner cover 20 is similar to the connection method between the first cylinder body 6221 and the inner cover 20, and will not be elaborated here.

[0043] Specifically, when processing the inner cover 20, a first through hole for installing the first pipe body 311 and a second through hole for installing the second pipe body 312 are formed on the inner cover 20 by die stamping, ensuring the accuracy of the position degree of the first through hole and the second through hole, and further ensuring the accuracy of the position degree of the first pipe body 311 and the second pipe body 312; a third through hole is provided on the end plate 6223 of the first cylinder body 6221, and a fourth through hole is provided on the end plate of the second cylinder body 6222. The third through hole corresponds to the first through hole, and the fourth through hole corresponds to the second through hole. The first pipe body 311 passes through the first through hole and the third through hole, and the second pipe body 312 passes through the second through hole and the fourth through hole.

[0044] In this embodiment, the mounting seat 60 (specifically the seat body 62) is fixed and positioned on the inner cover 20 through the first pipe body 311 and the second pipe body 312. The transmission member 50 is assembled on the mounting seat 60, realizing direct positioning. There is no need to weld a fixing seat on the inner cover 20 as in the related art, making the positions of the mounting seat 60 and the transmission member 50 more reliable. During the automatic exhaust process, the height at which the transmission member 50 is lifted by the driving member 40 is stable and will not be stuck.

[0045] Correspondingly, the valve body 32 includes a first valve body 321 provided above the first pipe body 311 and a second valve body 322 provided above the second pipe body 312; the ejector rod 54 includes a first ejector rod 541 located below the first valve body 321 and a second ejector rod 542 located below the second valve body 322. Both the first ejector rod 541 and the second ejector rod 542 are connected to the main body rod 51 and can synchronously abut against the first valve body 321 and the second valve body 322. Of course, in an embodiment not shown in the figure, the first ejector rod and the second ejector rod can also be controlled separately, thereby realizing separate control of the first valve body and the second valve body.

[0046] As Figures 3 to 5 and Figure 9 shown, the transmission member 50 is a lever structure, which includes a main body rod 51, a rotating shaft 52 disposed in the middle of the main body rod 51, a push plate 53 disposed at the first end of the main body rod 51, and a push rod 54 disposed at the second end of the main body rod 51. The driving member 40 can push the push plate 53 to drive the lever structure to swing, and the push rod 54 is located below the valve body 32. By the swing of the lever structure, the valve body 32 is driven to lift under the drive of the driving member 40, which has the advantages of simple structure and easy control.

[0047] Specifically, in this embodiment, the driving member 40 is a solenoid valve structure, which includes a solenoid valve 41 and a push rod 42. The solenoid valve 41 can drive the push rod 42 to move horizontally. When the push rod 42 moves horizontally, it pushes the push plate 53, so that the lever structure swings around the rotating shaft 52. When the lever structure swings, the push rod 54 moves upward to push the valve body 32 to achieve exhaust.

[0048] Of course, in the embodiments not shown in the figure, the transmission member is not limited to the lever structure, and it can be a translation structure or other structures; the driving member is not limited to the solenoid valve, and it can be an operation button or other structures.

[0049] Specifically, as Figure 3 shown, when the transmission member 50 is in the natural state (that is, the transmission member 50 does not push the valve body 32), the push plate 53 is in the vertical state or close to the vertical state, and the push plate 53 has a certain height. When the transmission member 50 floats up and down with the inner cover 20, the pushing end of the push rod 42 of the driving member 40 always has an overlapping part with the push plate 53 in the height direction.

[0050] As Figures 4 to 8 shown, the lever structure is disposed below the mounting seat 60. Among them, an avoidance opening 601 is provided on the mounting seat 60, and the push rod 54 and at least part of the main body rod 51 are correspondingly disposed with the avoidance opening 601; the setting of the avoidance opening 601 can avoid the push rod 54 and the main body rod 51, so that the push rod 54 can smoothly pass through the mounting seat 60 to abut against the valve body 32.

[0051] As Figures 4 to 6 and Figures 8 to 9 shown, a rotating shaft seat 63 is provided at the lower part of the mounting seat 60, and a rotating shaft hole 602 is provided on the rotating shaft seat 63. The rotating shaft 52 is rotatably inserted into the rotating shaft hole 602. Through the cooperation between the rotating shaft 52 and the rotating shaft hole 602, the transmission member 50 is swingably connected to the mounting seat 60, which has the advantages of simple structure and reliable connection.

[0052] As Figure 8 and Figure 9As shown, the lower part of the mounting seat 60 is provided with a first rotating shaft seat 631 and a second rotating shaft seat 632 at intervals. A first rotating shaft hole 6021 is provided on the first rotating shaft seat 631, and a second rotating shaft hole 6022 is provided on the second rotating shaft seat 632. The rotating shaft 52 includes a first shaft body 521 and a second shaft body disposed on both sides of the main body rod 51. The main body rod 51 is located between the first rotating shaft seat 631 and the second rotating shaft seat 632. The first shaft body 521 is rotatably inserted into the first rotating shaft hole 6021, and the second shaft body is rotatably inserted into the second rotating shaft hole 6022. Among them, in the direction from top to bottom, the distance between the first rotating shaft seat 631 and the second rotating shaft seat 632 gradually increases; when installing the transmission member 50, align the first shaft body 521 and the second shaft body of the transmission member 50 below the first rotating shaft seat 631 and the second rotating shaft seat 632, and then move the transmission member 50 from bottom to top until the first shaft body 521 is snapped into the first rotating shaft hole 6021 and the second shaft body is snapped into the second rotating shaft hole 6022, making the distance between the lower ends of the first rotating shaft seat 631 and the second rotating shaft seat 632 larger, which is convenient for aligning the transmission member 50 and simplifies the installation operation. Specifically, in this embodiment, guiding inclined surfaces are provided on the relatively arranged surfaces of the first rotating shaft seat 631 and the second rotating shaft seat 632 to guide the first shaft body 521 and the second shaft body.

[0053] The first rotating shaft seat 631 and the second rotating shaft seat 632 are relatively arranged to form a snap structure, and the transmission member 50 is snapped into the snap structure through the first shaft body 521 and the second shaft body.

[0054] As Figure 8 and Figure 9 shown, in the direction from bottom to top, the end face of the first shaft body 521 is inclined towards the second shaft body. That is, a guiding inclined surface is also provided on the end face of the first shaft body 521, which can facilitate the alignment between the first shaft body 521 and the first rotating shaft seat 631 and guide the first shaft body 521. Preferably, a guiding inclined surface is also provided on the end face of the second shaft body.

[0055] Specifically, when describing the present application, the "upper" and "lower" used both refer to the "upper" and "lower" in the state where the cover body assembly is assembled and covered above the pot body assembly. When specifically assembling the cover body assembly, it is not limited to installing the transmission member 50 on the mounting seat 60 in the direction from bottom to top. The two components can also be inverted and then the transmission member 50 can be installed on the mounting seat 60 in the direction from top to bottom.

[0056] As Figures 1 to 7As shown, the mounting base 60 includes a sealing piece 61 and a base body 62 connected below the sealing piece 61. The transmission member 50 is disposed below the base body 62. The exhaust pipe 31 passes through the sealing piece 61. The sealing piece 61 is in sealing fit with both the exhaust pipe 31 and the upper cover 10. The second end of the transmission member 50 can push up at least part of the sealing piece 61 to drive the valve body 32 to switch from the blocking state to the exhaust state. In this embodiment, the exhaust pipe 31 passes through the base body 62 and the sealing piece 61. The sealing piece 61 is in sealing fit with both the upper cover 10 and the exhaust pipe 31. When the exhaust structure 30 exhausts, the discharged steam, condensed water, etc. are directly discharged to the outside of the cover assembly or remain in the mounting base 60, and will not enter between the upper cover 10 and the inner cover 20. Specifically, the sealing piece 61 is a flexible structure for achieving the sealing fit with the exhaust pipe 31 and the upper cover 10, and the base body 62 is a rigid structure for mounting the transmission member 50. Such a setting has the advantage of simple structure.

[0057] As Figure 2 , Figure 4 and Figure 6 shown, the sealing piece 61 includes a piece main body 611, a connecting ring 612 disposed on the outer periphery of the piece main body 611, and a folding structure 613 connecting the piece main body 611 and the connecting ring 612. Among them, the exhaust pipe 31 passes through the piece main body 611, and the connecting ring 612 is connected to the upper cover 10. In this embodiment, due to the setting of the double exhaust valves, there will be a situation where one of the exhaust valves is disposed off the center of the cover assembly or both exhaust valves are disposed off the center of the cover assembly. When the inner cover 20 and the exhaust structure 30 rotate, they will drive the base body 62 to move and perform eccentric rotation or rotation with the rotation center outside the base body 62. By providing the folding structure 613 between the piece main body 611 and the connecting ring 612, the piece main body 611 can move relative to the connecting ring 612, that is, when the base body 62 rotates, the piece main body 611 moves while the connecting ring 612 remains stationary, taking into account both the lateral rotation ability of the base body 62 and the sealing ability of the sealing piece 61.

[0058] In this embodiment, the avoidance opening 601 and the rotating shaft seat 63 are both provided on the base body 62. The ejector rod 54 is located below the sealing piece 61.
