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, a pressure cooking appliance with a multi-speed pressure regulating function has multiple pressure limiting pressures. Users can select a suitable pressure limiting pressure according to the type of food to be cooked. For example, the cooking pressure required for tendon and meat is different from that required for ingredients such as lotus root, sweet potato and potato, which makes the cooked food taste better.

[0003] Generally, such cooking appliances require users to manually select the pressure; cooking control is achieved through a built-in control program, and users can select a cooking program through a control panel on the cooking appliance before cooking. However, when users operate, the selected pressure and the selected cooking program may not match, which will result in poor cooking results and even overflow, seriously affecting the user 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 the selected pressure and the selected cooking program may not match when the user operates.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a cover assembly is provided, which is arranged on a pot body, wherein the cover assembly includes: a cover body; an exhaust pipe, which is passed through the cover body; a pressure limiting valve, which is movably arranged above the exhaust pipe in the vertical direction and has a plurality of working positions; a driving structure, which is rotatably arranged on the cover body and cooperates with the driving of the pressure limiting valve; a switching structure, including a guide surface and a guide block cooperating with the guide surface, one of the guide surface and the guide block is arranged on the driving structure, and the other of the guide surface and the guide block is arranged on the cover body, when the driving structure rotates, the guide block moves along the guide surface and drives the driving structure to move in the vertical direction, thereby driving the pressure limiting valve to switch between a plurality of working positions; an induction structure, including a first induction member and a second induction member that cooperate with each other, the first induction member is arranged on the cover body or the pot body, and the second induction member is arranged on the driving structure.

[0006] By applying the technical solution of the utility model, the driving structure will drive the pressure limiting valve to move in the vertical direction during the rotation process, and then drive the pressure limiting valve to switch the working position, so as to realize multi-stage pressure limiting. The cover assembly also includes a sensing structure, which includes a first sensing member arranged on the cover or the pot body and a second sensing member arranged on the driving structure. When the driving structure rotates, the second sensing member will move with the driving structure, while the position of the first sensing member at this time remains unchanged, and then the sensing signal received by the first sensing member will be different. According to the different sensing signals, it can be determined which working position the pressure limiting valve is in at this time, and the sensing signal is transmitted to the control panel. Through the control program, the user is restricted to only select the cooking program corresponding to the working position, or a warning signal is issued when the user selects a cooking program that is not compatible with the working position, so that the user can make adjustments in time, so that the subsequent cooking process can proceed smoothly. Therefore, the technical solution of the present application can effectively solve the problem of incompatibility between the selected pressure and the selected cooking program when the user operates in the related technology.

[0007] Furthermore, the second sensing member includes a magnetic member, and the first sensing member includes a plurality of magnetic switches. When the driving structure drives the pressure limiting valve to different working positions, the magnetic member corresponds to different magnetic switches. The working position of the pressure limiting valve is detected by the cooperation between the magnetic member and the magnetic switch, which has the advantage of a simple structure.

[0008] Furthermore, the driving structure includes a turntable and a connecting rod, the first end of the connecting rod is connected to the turntable, the magnetic member is arranged at the second end of the connecting rod, and a plurality of magnetic switches are arranged at intervals in the circumferential direction of the cover body. The turning stroke of the turntable is amplified by arranging the connecting rod, so that even if the turntable rotates only a small angle, the second sensing member arranged at the second end of the connecting rod can move a large distance, thereby reducing the requirement for the sensing sensitivity of the first sensing member.

[0009] Furthermore, the guide surface includes a plurality of working surfaces and at least one inclined connection surface arranged in sequence in the circumferential direction and the axial direction of the pressure limiting valve, and each two adjacent working surfaces are connected by an inclined connection surface. When the driving structure rotates, the guide block can cooperate with different working surfaces to place the pressure limiting valve in different working positions. The cooperation between the guide block and the guide surface realizes multi-speed pressure regulation to adapt to the pressure required by different foods, which has the advantages of good cooking effect, simple structure and easy operation.

[0010] Furthermore, the multiple working surfaces include a high-pressure surface, a low-pressure surface, and a non-pressure surface arranged in sequence from low to high, and the multiple magnetic switches include a first switch and a second switch. When the guide block cooperates with the low-pressure surface, the magnetic member cooperates with the first switch inductively, and when the guide block cooperates with the non-pressure surface, the magnetic member cooperates with the second switch inductively. By setting two magnetic switches to detect the three working positions of the pressure-limiting valve, the number of magnetic switches is reduced, thereby reducing the cost of the cover assembly.

[0011] Furthermore, the cover assembly further includes an indication structure, which includes a plurality of status marks and an indication member, wherein the plurality of status marks are arranged on one of the cover and the drive structure, and the indication member is arranged on the other of the cover and the drive structure, and when the pressure limiting valve is in different working positions, the indication member is aligned with different status marks. During use, the user can judge the working position of the pressure limiting valve by the alignment relationship between the indication member and the status mark, and can also operate the drive structure according to the alignment relationship between the indication member and the status mark, which is convenient for the user.

[0012] Furthermore, the switching structure also includes a guide groove, the upper and lower walls of the guide groove form two guide surfaces, and the guide block is inserted in the guide groove. The lower guide surface can support the guide block, and the upper guide surface stops the guide block and thus limits the driving structure from upwardly separating from the cover assembly.

[0013] According to another aspect of the utility model, a cooking utensil is provided, comprising a pot body and a cover assembly arranged on the pot body, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem in the related art that the selected pressure and the selected cooking program may not match when the user operates, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

[0014] Furthermore, the cooking appliance further comprises a control panel disposed in the pot body, and the first induction element is electrically connected to the control panel to transmit an induction signal to the control panel. The control panel can receive the induction signal transmitted by the first induction element, and through a control program, restrict the user to only be able to select a cooking program corresponding to the working position, or issue a warning signal when the user selects a cooking program that is not suitable for the working position, so as to facilitate the user to make adjustments in time, so that the subsequent cooking process can proceed smoothly.

[0015] Furthermore, the pot body includes a shell and a middle plate arranged on the top of the shell, and the first induction element is arranged on the middle plate. This arrangement facilitates the electrical connection between the first induction element and the control board, and also enables the first induction element to be arranged as close as possible to the second induction element to achieve induction coordination between the two.

[0039] like Figures 1 to 7 , Fig.10 and Fig.11 As shown, the present application provides a cover assembly. 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 structure 40, a switching structure 50 and a sensing structure 60. Among them, the exhaust pipe 20 is penetrated through the cover body 10; the pressure limiting valve 30 is movably arranged above the exhaust pipe 20 in the vertical direction and has multiple working positions; the driving structure 40 is rotatably arranged on the cover body 10 and cooperates with the driving of the pressure limiting valve 30; the switching structure 50 includes a guide surface 51 and a guide block 52 cooperating with the guide surface 51, one of the guide surface 51 and the guide block 52 is arranged on the driving structure 40, and the other of the guide surface 51 and the guide block 52 is arranged on the cover body 10. When the driving structure 40 rotates, the guide block 52 moves along the guide surface 51 and drives the driving structure 40 to move in the vertical direction and then drives the pressure limiting valve 30 to switch between multiple working positions; the sensing structure 60 includes a first sensing member 61 and a second sensing member 62 that cooperate with each other, the first sensing member 61 is arranged on the cover body 10 or the pot body 1, and the second sensing member 62 is arranged on the driving structure 40.

[0040] By applying the technical solution of this embodiment, the driving structure 40 will drive the pressure limiting valve 30 to move in the vertical direction during the rotation process, thereby driving the pressure limiting valve 30 to switch the working position, and realizing multi-level pressure limiting. The cover assembly also includes a sensing structure 60, which includes a first sensing member 61 arranged on the cover body 10 or the pot body 1 and a second sensing member 62 arranged on the driving structure 40. When the driving structure 40 rotates, the second sensing member 62 will move with the driving structure 40, while the position of the first sensing member 61 at this time remains unchanged, and then the sensing signal received by the first sensing member 61 will be different. According to the different sensing signals, it can be determined which working position the pressure limiting valve 30 is in at this time, and the sensing signal is transmitted to the control panel. Through the control program, the user is restricted to only select the cooking program corresponding to the working position, or when the user selects a cooking program that is not compatible with the working position, a warning signal is issued, so that the user can make adjustments in time, so that the subsequent cooking process can proceed smoothly. Therefore, the technical solution of this embodiment can effectively solve the problem that the selected pressure and the selected cooking program may not match when the user operates in the related art.

[0041] Specifically, the above-mentioned “the pressure-limiting valve 30 has a plurality of working positions” means that the pressure-limiting valve 30 has two or more working positions.

[0042] like Fig.10 and Fig.11 As shown, the second sensing member 62 includes a magnetic member, and the first sensing member 61 includes a plurality of magnetic switches. When the driving structure 40 drives the pressure limiting valve 30 to reach different working positions, the magnetic member corresponds to different magnetic switches. The working position of the pressure limiting valve 30 is detected by the cooperation between the magnetic member and the magnetic switch, which has the advantage of a simple structure.

[0043] Specifically, in this embodiment, the second induction element 62 is a magnet, and the first induction element 61 is a reed switch or a Hall switch that can be turned on and off according to whether there is a magnetic field around it.

[0044] like Figure 2 , Figure 7 , Fig.10 and Fig.11As shown, the driving structure 40 includes a rotating disk 41 and a connecting rod 42, the first end of the connecting rod 42 is connected to the rotating disk 41, the magnetic member is arranged at the second end of the connecting rod 42, and a plurality of magnetic switches are arranged at intervals in the circumferential direction of the cover body 10. Since the actual rotation amplitude of the driving structure 40 is small when the driving structure 40 rotates, if the sensing structure is arranged at a position close to the center of the driving structure 40, the position change of the second sensing member 62 is small when the pressure limiting valve 30 is in different working positions, which requires a higher sensing sensitivity of the first sensing member 61. By setting the connecting rod 42, the rotation stroke of the rotating disk 41 is amplified, so that even if the rotating disk 41 only rotates a small angle, the second sensing member 62 arranged at the second end of the connecting rod 42 can move a large distance, reducing the requirements for the sensing sensitivity of the first sensing member 61.

[0045] like Figure 2 , Figure 7 , Fig.10 and Fig.11 As shown, the connecting rod 42 includes a first rod body 421 and a second rod body 422 extending in the same direction and capable of sliding fit, so that the total length of the connecting rod 42 can be changed, so that the connecting rod 42 can adapt to the situation where the pressure limiting valve 30 is set away from the center of the cover assembly or the outer contour of the cover assembly is a non-circular structure. Among them, the first rod body 421 is connected to the rotating disk 41, and the second sensor 62 is arranged at an end of the second rod body 422 away from the pressure limiting valve 30. Specifically, in this embodiment, a guide groove is arranged on the first rod body 421, and a guide slider is arranged on the second rod body 422. The guide slider is inserted in the guide groove and can move along the guide groove, thereby realizing the sliding fit of the first rod body 421 and the second rod body 422.

[0046] like Figure 5 and Figure 7 As shown, a connecting rod is provided below the turntable 41, a connecting hole is provided on the first rod body 421, and the first rod body 421 is fixedly connected to the turntable 41 through a fastener penetrating the connecting hole and the connecting rod. Of course, in an embodiment not shown in the figure, the connecting hole can also be set as a hole with a larger diameter, and a multi-petal buckle structure is provided below the connecting column, and the connecting rod is installed on the turntable through the buckle structure and the connecting hole.

[0047] like Figure 1 , Figure 4 and Figure 5As shown, the guide surface 51 includes a plurality of working surfaces 511 and at least one inclined connection surface 512 which are sequentially arranged in the circumferential direction and the axial direction of the pressure limiting valve 30. Each two adjacent working surfaces 511 are connected by an inclined connection surface 512. When the driving structure 40 rotates, the guide block 52 can cooperate with different working surfaces 511 to make the pressure limiting valve 30 in different working positions. When in use, the user can operate the driving structure 40 to rotate so that the guide block 52 moves along the guide surface 51. When the guide block 52 moves along the guide surface 51, it will drive the driving structure 40 to move in the vertical direction, and then drive the pressure limiting valve 30 to move in the vertical direction to switch the working position. Through the cooperation between the guide block 52 and the guide surface 51, multi-speed pressure regulation is achieved to adapt to the pressure required by different foods, which has the advantages of good cooking effect, simple structure and easy operation.

[0048] Specifically, in this embodiment, the pressure limiting valve 30 has three working positions, such as Figure 2 , Figure 3 and Figure 6 As shown, the pressure-limiting valve 30 includes an inner valve 31 and an outer valve 32 sleeved outside the inner valve 31, the inner valve 31 includes a first valve body 311, a valve cover 312 arranged above the first valve body 311 and a first flange 313 arranged on the outer periphery of the first valve body 311, the valve cover 312 protrudes outward from the first valve body 311, and a vertical adjustment space is formed between the outer edge of the valve cover 312 and the first flange 313; the outer valve 32 includes a cylindrical second valve body 321, an outward turning flange 322 arranged above the second valve body 321 and a second flange 323 arranged on the inner surface of the second valve body 321, the second flange 323 is located in the vertical adjustment space and the height of the vertical adjustment space is greater than the height of the second flange 323. The outer valve 32 can move in the vertical direction relative to the inner valve 31. When the second flange 323 abuts against the first flange 313, the inner valve 31 and the outer valve 32 are pressed on the exhaust pipe 20 together to achieve high-pressure cooking; when the second flange 323 is separated from the first flange 313 and the outer edge of the valve cover 312, only the inner valve 31 is pressed on the exhaust pipe 20 to achieve low-pressure cooking; when the second flange 323 abuts against the outer edge of the valve cover 312, the outer valve 32 lifts the inner valve 31, so that neither the inner valve 31 nor the outer valve 32 is pressed on the exhaust pipe 20, to achieve pressure-free cooking.

[0049] like Figure 2 and Figure 3 As shown, the turntable 41 is supported below the outward turning edge 322. When the turntable 41 moves in the vertical direction, it will drive the outer valve 32 to move in the vertical direction, thereby switching the pressure limiting valve 30 between the high-pressure cooking position, the low-pressure cooking position and the no-pressure cooking position.

[0050] Specifically, Figure 4 and Figure 5 As shown, the multiple working surfaces 511 include a high-pressure surface 5111, a low-pressure surface 5112, and a non-pressure surface 5113 arranged in order from low to high, and the multiple magnetic switches include a first switch 611 and a second switch 612. When the guide block 52 cooperates with the low-pressure surface 5112, the magnetic member cooperates with the first switch 611 inductively, and when the guide block 52 cooperates with the non-pressure surface 5113, the magnetic member cooperates with the second switch 612 inductively. When the guide block 52 cooperates with the high-pressure surface 5111, the pressure limiting valve 30 is in the high-pressure cooking position; when the guide block 52 cooperates with the low-pressure surface 5112, the pressure limiting valve 30 is in the low-pressure cooking position; when the guide block 52 cooperates with the non-pressure surface 5113, the pressure limiting valve 30 is in the non-pressure cooking position. In this embodiment, only two magnetic switches are provided for the three working positions of the pressure limiting valve 30. When the control panel receives the sensing signal of the first switch 611, it indicates that the pressure limiting valve 30 is in the low-pressure cooking position; when the control panel receives the sensing signal of the second switch 612, it indicates that the pressure limiting valve 30 is in the non-pressure cooking position; when the control panel receives neither the sensing signal of the first switch 611 nor the sensing signal of the second switch 612, it indicates that the pressure limiting valve 30 is in the high-pressure cooking position. By providing two magnetic switches to detect the three working positions of the pressure limiting valve 30, the number of magnetic switches is reduced, thereby reducing the cost of the cover assembly.

[0051] In this embodiment, the guide surface 51 has three working surfaces 511 and two inclined connecting surfaces 512 .

[0052] like Figure 1 , Figure 5 and Figure 8 As shown, the cover assembly also includes an indication structure, which includes a plurality of status marks 11 and an indication member 43, wherein the plurality of status marks 11 are arranged on one of the cover 10 and the drive structure 40, and the indication member 43 is arranged on the other of the cover 10 and the drive structure 40, and when the pressure limiting valve 30 is in different working positions, the indication member 43 is aligned with different status marks 11. During use, the user can judge the working position of the pressure limiting valve 30 by the alignment relationship between the indication member 43 and the status mark 11, and can also operate the drive structure 40 according to the alignment relationship between the indication member 43 and the status mark 11, which is convenient for the user.

[0053] Specifically, in the present embodiment, a plurality of status marks 11 are disposed on the upper surface of the cover body 10 , and the indicator 43 is disposed on the outer surface of the turntable 41 .

[0054] like Figure 1 , Figure 4 and Figure 5 As shown, after the cover is closed, the user can turn the turntable 41 from Figure 1The function gear position in the upper right middle position is turned to the function gear position in the middle. At this time, the guide block 52 slides from the lowest position in the guide groove 53 to the middle position, and the turntable 41 moves up. The turntable 41 lifts the outer valve 32, so that the outer valve 32 and the inner valve 31 are separated. At this time, only the gravity of the inner valve 31 presses on the exhaust pipe 20, which is a light valve cooking state; in the process of rotating the turntable 41, the turntable 41 will drive the connecting rod 42 to rotate, and the second sensor 62 on the connecting rod 42 will also move to the position of the first switch 611. The signal of the first switch 611 being turned on is transmitted to the control panel, and the user can choose light valve cooking at this time. function for cooking; the second switch 612 corresponds to the pressure-free cooking state. When the second sensor 62 on the connecting rod 42 rotates to the position of the second switch 612, the signal of the second switch 612 being turned on is transmitted to the control board. At this time, the user can select the pressure-free cooking function for cooking; the third function gear is the heavy valve cooking state, which corresponds to the turntable 41 driving the second sensor 62 to move to a position outside the first switch 611 and the second switch 612. At this time, the control board in the pot body 1 does not receive any signal, and the wireless temperature measurement module detects the lid is in place signal, which means that the cooking appliance is in the heavy valve cooking state.

[0055] like Figure 4 As shown, the switching structure 50 also includes a guide groove 53, and the upper and lower walls of the guide groove 53 form two guide surfaces 51, and the guide block 52 is inserted into the guide groove 53. The guide groove 53 guides the guide block 52, and the guide surface 51 located at the bottom can support the guide block 52, and the guide surface 51 located at the top stops the guide block 52, thereby limiting the driving structure 40 from upwardly separating from the cover assembly.

[0056] like Figure 4 As shown, the guide groove 53 is arranged on the valve seat 12 , the pressure limiting valve 30 is arranged in the valve seat 12 , and the valve seat 12 is fixedly connected to the cover body 10 .

[0064] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0065] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
