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, the pressure-limiting pressure of the pressure cooking appliance capable of multi-level pressure regulation is adjustable, so that different pressure-limiting pressures can be selected when cooking different foods, thereby achieving better cooking effects.

[0003] In order to transmit the status signal of the pressure limiting valve to the control board to realize intelligent cooking, a connecting rod can be set on the driving structure of the pressure limiting valve and a signal sensing component can be set at the far end of the connecting rod. The connecting rod will swing with the rotation of the driving structure, thereby causing the position of the signal sensing component to change, and the signal received by the control board will also change. The status of the pressure limiting valve can be judged based on the changed signal.

[0004] However, this signal transmission method is only applicable to a cover body with a circular cross-section and a pressure-limiting valve set in the middle position. When the pressure-limiting valve is set at a position deviated from the center of the cover body or the cross-section of the cover body is a non-circular structure, the distal end of the connecting rod will swing out of the range of the cover body during rotation. Utility Model Content

[0005] 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 of limited usage scenarios of the signal transmission method in the related art.

[0007] By applying the technical solution of the utility model, when the driving member rotates to drive the pressure-limiting valve to switch the exhaust position, the telescopic rod assembly will also swing along with the driving member, thereby causing the position of the first sensing member located at the second end of the telescopic rod assembly to change, thereby causing the sensing signal of the second sensing member to change, thereby realizing the detection of the exhaust position of the pressure-limiting valve. Among them, the telescopic rod assembly can be telescoped so that the overall length of the telescopic rod assembly can be changed.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0042] like Figure 1 , Figure 2 , Fig.11 and Fig.12 As shown, the present application provides a cover assembly, and the embodiment of the cover assembly of the present application includes: an outer cover 10, an exhaust rod 20, a driving member 40, a telescopic rod assembly 50 and a sensing assembly 60. Among them, the exhaust rod 20 is arranged through the outer cover 10; the pressure limiting valve 30 is movably arranged at the upper end of the exhaust rod 20 along the vertical direction and has multiple exhaust positions; the driving member 40 is rotatably arranged on the outer cover 10, and when the driving member 40 rotates, it can drive the pressure limiting valve 30 to switch between multiple exhaust positions; the first end of the telescopic rod assembly 50 is connected to the driving member 40 and can rotate synchronously with the driving member 40; the sensing assembly 60 includes a first sensing member 61 and a second sensing member 62 for induction matching, the first sensing member 61 is arranged at the second end of the telescopic rod assembly 50, and the second sensing member 62 is arranged on the outer cover 10 or the pot body 1.

[0043] By applying the technical solution of this embodiment, when the driving member 40 rotates to drive the pressure limiting valve 30 to switch the exhaust position, the telescopic rod assembly 50 will also swing along with the driving member 40, thereby causing the position of the first sensing member 61 located at the second end of the telescopic rod assembly 50 to change, thereby causing the sensing signal of the second sensing member 62 to change, thereby realizing the detection of the exhaust position of the pressure limiting valve 30. Among them, the telescopic rod assembly 50 can be telescoped so that the overall length of the telescopic rod assembly 50 can be changed. When the pressure limiting valve 30 and the driving member 40 are installed at a non-central position of the outer cover 10 or the cross-section of the outer cover 10 is a non-circular structure, the telescopic rod assembly 50 can change its length to adapt to the distance from the driving member 40 to the edge position of the outer cover 10, thereby preventing the second end of the telescopic rod assembly 50 from rotating out of the range of the outer cover 10, thereby realizing the signal transmission function. Therefore, the technical solution of this embodiment can effectively solve the problem of limited use scenarios of the signal transmission method in the related art.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the telescopic rod assembly 50 includes a first rod body 51, a second rod body 52 and a sliding matching structure 53. The first rod body 51 is connected to the driving member 40, the first sensing member 61 is arranged on the second rod body 52, and the sliding matching structure 53 includes a sliding groove 531 and a sliding block 532 slidably arranged in the sliding groove 531. One of the sliding groove 531 and the sliding block 532 is arranged on the first rod body 51, and the other of the sliding groove 531 and the sliding block 532 is arranged on the second rod body 52. ​​The second rod body 52 and the first rod body 51 can move relative to each other along the extension direction of the sliding groove 531. The sliding matching structure 53 enables the first rod body 51 and the second rod body 52 to move relative to each other along the extension direction of the sliding groove 531, thereby realizing the adjustment of the overall length of the telescopic rod assembly 50, which has the advantages of simple structure and easy processing.

[0045] It should be noted that the above-mentioned "the second rod 52 and the first rod 51 can move relative to each other along the extension direction of the sliding groove 531" means that the second rod 52 and the first rod 51 can only move relative to each other, and cannot rotate or perform other movements. Specifically, in this embodiment, the first sensing element 61 is a magnet, and the second sensing element 62 is a reed switch or a Hall switch.

[0046] Specifically, Figure 1 and Figure 3 As shown, in this embodiment, the pressure-limiting valve 30 includes an inner valve body 31 and an outer valve body 32 that are nested together. The inner valve body 31 includes a first valve body 311, a valve cover 312 arranged at the upper end of the first valve body 311, and a first flange 313 arranged on the outer surface of the first valve body 311. The outer edge of the valve cover 312 protrudes from the outer surface of the first valve body 311, and the outer edge of the valve cover 312 and the first flange 313 are arranged at intervals; the outer valve body 32 includes a second valve body 321, an outer flange 322 arranged at the upper end of the second valve body 321, and a second flange 323 arranged on the inner surface of the second valve body 321, and the second flange 323 is located between the outer edge of the valve cover 312 and the first flange 313. The outer valve body 32 can move in the axial direction relative to the inner valve body 31. When the second flange 323 abuts against the first flange 313, the inner valve body 31 and the outer valve body 32 are pressed on the exhaust rod 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 body 31 is pressed on the exhaust rod 20 to achieve low-pressure cooking; when the second flange 323 abuts against the outer edge of the valve cover 312, the outer valve body 32 lifts the inner valve body 31, so that neither the inner valve body 31 nor the outer valve body 32 is pressed on the exhaust rod 20, to achieve pressure-free cooking.

[0047] like Figure 4 As shown, the driving member 40 includes a turntable 41, a connecting column 42 arranged on the turntable 41 and extending downward, and a sliding column 43 arranged on the turntable 41 and extending outward. The turntable 41 is sleeved on the outer periphery of the pressure-limiting valve 30 and supported below the outer flange 322 of the outer valve body 32. The outer cover 10 is provided with a guide bevel extending along the circumferential direction of the pressure-limiting valve 30. The sliding column 43 on the turntable 41 is inserted into the guide bevel. The guide bevel has a plurality of locking sections. When the user rotates the turntable 41, the sliding column 43 moves along the guide bevel, so that the turntable 41 moves in the vertical direction. When the turntable 41 moves in the vertical direction, it can drive the outer valve body 32 to move synchronously, thereby realizing the switching of the exhaust position of the pressure-limiting valve 30.

[0048] Of course, in an embodiment not shown in the figure, the driving member can also be set to a structure that can only rotate and cannot move in the vertical direction, and the sliding column is set on the outer valve body. When the driving member rotates, the outer valve body is driven to rotate synchronously. During the rotation of the outer valve body, the sliding column moves in the guide groove, thereby causing the outer valve body to move in the vertical direction.

[0049] like Figure 5 As shown, a first connecting hole 511 is provided on the first rod body 51, and the first rod body 51 is fixedly connected to the rotating disk 41 through a fastener penetrating the first connecting hole 511 and the connecting column 42. Of course, in an embodiment not shown in the figure, the first connecting hole can also be set as a through hole with a larger diameter, and a plurality of elastic buckles are set at the end of the second connecting column, and the connection between the first rod body and the rotating disk is realized by the snap-fitting between the elastic buckle and the first connecting hole.

[0050] like Figure 5 and Figure 6 As shown, the first rod body 51, the second rod body 52 and the sliding groove 531 extend in the same direction, and the sliding block 532 is locked in rotation with the sliding groove 531. By locking the sliding block 532 and the sliding groove 531, the first rod body 51 and the second rod body 52 can only move relative to each other, which has the advantages of simple structure and reliable guidance.

[0051] Of course, in embodiments not shown in the figures, other methods may be used to achieve that the first rod body and the second rod body can only move relative to each other, for example, two parallel sliding grooves and two sliding blocks respectively inserted into the two sliding grooves are provided, or a guide structure is provided between the first rod body and the second rod body.

[0052] like Figure 6 , Fig.11 and Fig.12As shown, the sliding block 532 is a strip-shaped structure extending in the same direction as the sliding groove 531. The strip-shaped sliding block 532 realizes the anti-rotation fit with the sliding groove 531, which has the advantages of simple structure and reliable guidance. Of course, the anti-rotation fit with the sliding groove can also be realized by setting the cross section of the sliding block to a square or other shapes.

[0053] like Figure 6 , Fig.11 and Fig.12 As shown, the sliding block 532 includes a strip plate 5321 extending in the same direction as the sliding groove 531 and matching columns 5322 arranged at both ends of the strip plate 5321, the outer contour of the matching columns 5322 is a curved surface, and the matching columns 5322 protrude from the strip plate 5321 on both sides of the strip plate 5321. The matching columns 5322 are respectively arranged at both ends of the strip plate 5321 so that the sliding block 532 forms a long strip structure, ensuring the reliability of the guide; in addition, the outer contour of the matching columns 5322 is a curved surface and the matching columns 5322 protrude from the strip plate 5321 on both sides of the strip plate 5321, so that the contact area between the sliding block 532 and the sliding groove 531 is small when the sliding block 532 and the sliding groove 531 are matched, reducing the friction between the sliding groove 531 and the sliding block 532, so that the relative movement between the first rod body 51 and the second rod body 52 is smoother.

[0054] like Figure 1 , Figure 2 , Figure 8 , Fig.11 and Fig.12 As shown, the cover assembly further includes a strip guide groove 11 provided on the outer cover 10, and the second end of the telescopic rod assembly 50 is guided and matched with the strip guide groove 11. By providing the strip guide groove 11 and allowing the second end of the telescopic rod assembly 50 to guide and match with the strip guide groove 11, the position of the second end of the telescopic rod assembly 50 is limited, and in conjunction with the setting of the sliding matching structure 53, when the pressure limiting valve 30 is in different exhaust positions, the second end of the telescopic rod assembly 50 has a corresponding position, thereby facilitating the arrangement of the second sensor 62.

[0055] like Figure 1 , Figure 2 , Figure 8 , Fig.11 and Fig.12 As shown, the outer cover 10 includes a cover body 12 and a strip guide seat 13 disposed on the cover body 12, and the strip guide groove 11 is formed on the strip guide seat 13. By additionally providing the strip guide seat 13 and allowing the strip guide groove 11 to be disposed thereon, the processing of the strip guide groove 11 is facilitated.

[0056] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the cover assembly further includes a mounting seat 70 disposed at the second end of the telescopic rod assembly 50, the first sensing member 61 is disposed in the mounting seat 70, and the mounting seat 70 is inserted into the strip guide groove 11 and is guided and matched with the strip guide groove 11. By providing the mounting seat 70, the installation of the first sensing member 61 and the guiding and matching between the second end of the telescopic rod assembly 50 and the strip guide groove 11 are simultaneously achieved, thereby simplifying the structure of the cover assembly.

[0057] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig. 9 As shown, the mounting seat 70 includes a connecting column 71 and a mounting portion 72, the first sensing member 61 is arranged on the mounting portion 72, the connecting column 71 is connected between the mounting portion 72 and the telescopic rod assembly 50, the connecting column 71 is arranged in the strip guide groove 11, the telescopic rod assembly 50 and the mounting portion 72 are respectively located on both sides of the strip guide seat 13 and cooperate with the stopper of the strip guide seat 13. The mounting seat 70 is fixedly connected to the telescopic rod assembly 50, the telescopic rod assembly 50 and the mounting portion 72 are respectively located on both sides of the strip guide seat 13 and cooperate with the stopper of the strip guide seat 13, so that the second rod body 52 is limited in the vertical direction by the strip guide seat 13, thereby making the movement of the second rod body 52 more stable. Specifically, the diameter of the connecting column 71 is smaller than the groove width of the strip guide groove 11, and the length of the connecting column 71 is greater than the thickness of the strip guide seat 13. When the turntable 41 rotates back and forth, the connecting column 71 can move back and forth in the strip guide groove 11.

[0058] like Figure 6 As shown, a second connecting hole 521 is provided on the second rod body 52 , and the mounting seat 70 is fixedly connected to the second rod body 52 via a fastener penetrating through the second connecting hole 521 and the connecting column 71 .

[0059] Specifically, when the turntable 41 rotates, the first rod 51 and the second rod 52 swing and drive the mounting seat 70 to move in the strip guide groove 11. The mounting seat 70 moves back and forth in the strip guide groove 11 under the restriction of the strip guide groove 11. The track of the strip guide groove 11 is determined according to the shape of the whole machine, so the distance between the point on the track and the center of the turntable 41 is variable.

[0060] like Figure 1 , Figure 2 , Fig. 9 , Fig.11 and Fig.12As shown, the cover body 12 includes a cover 121 and a liner 122 disposed in the cover 121, the strip guide seat 13 is disposed on the liner 122 and spaced from the liner 122, the telescopic rod assembly 50 is located above the strip guide seat 13, and the mounting portion 72 is located between the liner 122 and the strip guide seat 13. The strip guide seat 13 is mounted on the liner 122 to facilitate the installation of the strip guide seat 13. The mounting portion 72 is arranged close to the liner 122, and when the second sensing member 62 is arranged on the pot body 1, the distance between the first sensing member 61 and the second sensing member 62 disposed on the mounting portion 72 is small, thereby ensuring the stability of the sensing signal. Specifically, in this embodiment, two third connecting holes 1221 are provided on the bushing 122, the strip guide seat 13 includes a seat body 132 and two connecting columns 133 arranged at both ends of the seat body 132, and the strip guide seat 13 is fixed to the upper surface of the bushing 122 by fasteners passing through the two pairs of connecting columns 133 and the third connecting holes 1221.

[0061] Specifically, in this embodiment, the cover assembly is a detachable cover structure, and a control board for controlling the cooking process is arranged in the pot body. The second sensor 62 is installed on the middle plate of the pot body 1 and is electrically connected to the control board to transmit the status signal of the pressure limiting valve 30 to the control board.

[0062] like Figures 10 to 12 As shown, the present application also provides a cooking utensil, and the embodiment of the cooking utensil of the present application includes a pot body 1 and a cover assembly disposed on the pot body 1, wherein the cover assembly is the above-mentioned cover assembly. The above-mentioned cover assembly can effectively solve the problem of limited use scenarios of the signal transmission method in the related art, and the cooking utensil with the above-mentioned cover assembly also has the above-mentioned advantages.

[0063] Specifically, in this embodiment, the cooking utensil is a pressure cooking utensil with a pressure regulating function. Of course, in embodiments not shown in the figure, the cooking utensil can also be a rice cooker, a low-pressure rice cooker, a soybean milk maker, a food processor, a cooking machine, an electric stew pot, a multi-function pot and other products.

[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.
