However, since the gear position indicator icon is provided on the housing and outside the knob, the space required for the printing area is relatively large. For increasingly miniaturized cooking utensils, there may not be a corresponding space for setting, which is not conducive to the miniaturization of the product.
[0045] In order to solve the above problems, Figures 1 to 11 As shown, the present application provides a cooking utensil which can avoid occupying a large printing space on the outer shell so as to realize product miniaturization.
[0046] like Figure 1 to Figure 2 As shown, specifically, the cooking appliance includes an outer shell 10, a switch assembly 20 and a knob assembly 30, wherein: an assembly hole 11 is provided on the outer shell 10; the switch assembly 20 includes a switch body 21 and a rotating shaft 22 rotatably connected relative to the switch body 21, the switch body 21 is arranged on the inner side of the outer shell 10, and the rotating shaft 22 passes through the assembly hole 11; the knob assembly 30 includes a knob 31 and a decorative member 32, the knob 31 is arranged on the outer side of the outer shell 10 and is connected to the rotating shaft 22, an avoidance hole 3121 is provided on the end surface of the knob 31, the decorative member 32 covers the end surface of the knob 31 and the decorative member 32 passes through the avoidance hole 3121 and is connected to the outer shell 10, the knob 31 is rotatably arranged relative to the decorative member 32, a pointer 311 is provided on one of the end surface of the knob 31 and the decorative member 32, and an indication mark 321 is correspondingly provided on the other.
[0047] The cooking utensil can be an electric hot pot, a cooking pot, an electric rice cooker, etc. When the cooking utensil is an electric hot pot or other pot mounted on a base, the outer shell 10 is the outer shell of the base; when the cooking utensil is an electric rice cooker or other pot with an inner pot placed inside the outer shell, the outer shell 10 is the outer shell of the entire cooking utensil.
[0048] In the cooking device provided by the embodiment of the utility model, the user can control the knob 31 to rotate relative to the outer shell 10, the knob 31 drives the rotating shaft 22 to rotate relative to the switch body 21, and the switch body 21 adjusts the gear of the cooking temperature, firepower, power and other parameters of the cooking device according to the rotation angle of the rotating shaft 22; because the decorative member 32 is fixed to the outer shell 10, the decorative member 32 is always fixed relative to the outer shell 10 when the knob 31 is rotated, and there is a printing space on the decorative member 32, the indication mark 321 or the pointer 311 can be set on the decorative member 32, so that there is no need to reserve a large printing space on the outer shell 10, so as to realize the miniaturization of the product;
[0049] The decorative part 32 may be printed with an indicator mark 321 or a pointer 311, and correspondingly, the other may be provided on the end face of the knob 31. Thus, when adjusting the gear, the user may refer to the position of the pointer 311 on the knob 31 relative to the indicator mark 321 on the decorative part 32. When the pointer 311 indicates the indicator mark 321 corresponding to the desired gear, the adjustment is completed, and the operation is simple and convenient.
[0050] The specific structure inside the switch body 21 and the connection method between the switch body 21 and the rotating shaft 22 are similar to the switch structure in the existing cooking utensils, and will not be described in detail here.
[0051] like Figure 1 to Figure 2 As shown, in the illustrated embodiment, the switch body 21 is further provided with an external thread 211, and the switch assembly 20 further includes a fixing member 23 with an internal thread, and the portion of the switch body 21 with the external thread 211 passes through the assembly hole 11 and is threadedly connected with the fixing member 23. The fixing member 23 cooperates with the external thread 211 of the switch body 21, and the outer shell 10 is clamped between the fixing member 23 and the portion of the switch body 21 that does not pass through the assembly hole 11, so that the switch body 21 is fixed to the outer shell 10. This installation method does not require additional assembly holes or processing of assembly parts on the outer shell 10, and is simple and convenient to operate, which is convenient for repairing or replacing the switch assembly 20, and can also ensure the stability and reliability of the connection between the switch body 21 and the outer shell 10. Of course, in other embodiments, the switch body 21 can also be fixedly connected to the outer shell 10 by other means such as screws and buckles.
[0052] like Figures 7 and 8As shown, the knob 31 includes a support body 312 and a hollow cylinder 313 sleeved outside the support body 312. The support body 312 is provided with an avoidance hole 3121, and the pointer 311 is provided at the edge of the support body 312 or the end of the cylinder 313. The user can hold the cylinder 313 to control the rotation of the knob 31 relative to the outer shell 10. Figure 3 and Figure 6 As shown, the decorative piece 32 includes a decorative sheet 322 and a fixing portion 324 disposed on the decorative sheet 322. The fixing portion 324 passes through the avoidance hole 3121 and is fixed to the outer shell 10. The indicator mark 321 is disposed on the decorative sheet 322. When the knob 31 rotates relative to the outer shell 10, the fixing portion 324 can slide relative to the knob 31 in the avoidance hole 3121. The avoidance hole 3121 can prevent the fixing portion 324 from interfering with the normal rotation of the knob 31, and can also limit the rotation range of the knob 31 relative to the outer shell 10 and the decorative piece 32. The decorative sheet 322 can cover the avoidance hole 3121 to prevent the avoidance hole 3121 from being exposed and affecting the aesthetics of the knob assembly 30, thereby ensuring that the knob assembly 30 has a regular appearance.
[0053] like Figure 2 and Figure 8 As shown, the knob 31 also has a mounting groove 314, and the decorative sheet 322 is at least partially located in the mounting groove 314. The support body 312 is sleeved on the side wall of the cylinder 313 and connected to the cylinder 313 in one piece or in a separate piece, so as to form the mounting groove 314 between the end surface of the support body 312 and the side wall of the cylinder 313. The support body 312 is connected to the inner side wall of the cylinder 313 away from the outer shell 10, that is, from Figure 7 When the knob 31 is viewed from the angle shown, both the support body 312 and the barrel 313 can be seen. At this time, the ends of the support body 312 and the barrel 313 form a mounting groove 314, the decorative sheet 322 is at least partially located in the mounting groove 314, and the pointer 311 is arranged at the end of the barrel 313. The mounting groove 314 is used to accommodate the decorative sheet 322, so as to prevent the decorative sheet 322 from protruding excessively from the knob 31 and increasing the overall volume of the knob assembly 30, and at the same time, it is convenient to align the pointer 311 on the knob 31 with the indicator mark 321 on the decorative sheet 322. In addition, the mounting groove 314 can also limit the relative position of the knob 31 and the decorative sheet 322, so as to ensure the stability of the knob 31 when it rotates relative to the outer shell 10 and the decorative member 32.
[0054] Alternatively, the support body 312 is sleeved on the end of the side wall of the cylinder, and the assembly groove 314 is provided on the side of the support body 312 away from the cylinder 313, that is, the support body 312 is connected to the end surface of the cylinder 313 away from the outer shell 10, that is, from Figure 7 When the knob 31 is viewed from the angle shown, only the support body 312 can be seen. At this time, the end of the support body 312 is provided with a mounting groove 314, and the pointer 311 is arranged at the edge of the support body 312.
[0055] When the decorative sheet 322 is partially located in the assembly groove 314, the end surface of the decorative sheet 322 away from the outer shell 10 protrudes from the end surface of the cylinder 313; when the decorative sheet 322 is completely located in the assembly groove 314, the end surface of the decorative sheet 322 away from the outer shell 10 is preferably flush with the end surface of the cylinder 313 to improve the aesthetics of the knob assembly 30, or the end surface of the decorative sheet 322 away from the outer shell 10 may also be recessed relative to the end surface of the cylinder 313. Of course, the knob 31 may also be provided without the assembly groove 314, and the decorative sheet 322 may be completely protruded from the end surface of the cylinder 313.
[0056] like Figure 2 and Figure 8 As shown, the knob 31 also includes a boss 315 formed by protruding from the support body 312, and the rotating shaft 22 is fixed to the boss 315. The boss 315 can be fitted with the rotating shaft 22 by interference fit to increase the contact area between the knob 31 and the rotating shaft 22 and improve the reliability of the connection between the two. Alternatively, the boss 315 can also be fixedly connected to the rotating shaft 22 by other means such as clamping, screws, etc.
[0057] like Figures 6 to 8 As shown, in the illustrated embodiment, the cross section of the rotating shaft 22 is circular and has a flat portion, and the boss 315 has a through hole 3151 of the same shape as the rotating shaft 22, so as to ensure that the rotating shaft 22 can be driven to rotate synchronously when the knob 31 is rotated, and to avoid slipping of the two. Of course, in other embodiments, the cross section of the rotating shaft 22 can also be set to a non-rotating structure of regular or irregular shapes such as a triangle, a square, an ellipse, etc., and the boss 315 has a through hole 3151 of the same shape as the rotating shaft 22. At the same time, one of the outer wall of the rotating shaft 22 and the inner wall of the through hole 3151 also has a groove, and the other has a protrusion that matches the groove, so as to improve the reliability of the connection between the rotating shaft 22 and the boss 315.
[0058] like Figure 6 As shown, a second reinforcing rib 316 is further provided on the side of the support body 312 away from the decorative sheet 322. The second reinforcing rib 316 is used to increase the strength of the support body 312, to prevent the friction between the support body 312 and the decorative sheet 322 during the rotation process, and the collision between the fixing portion 324 and the support body 312, which may cause the support body 312 to deform or break, thereby extending the service life of the knob 31.
[0059] Furthermore, the support body 312, the cylinder 313, the boss 315 and the second reinforcing rib 316 can be integrally formed to ensure the stability and reliability of the connection between the parts and facilitate the processing of the knob 31. The pointer 311 can be a protrusion integrally provided on the support body 312 or the cylinder 313, a groove provided on the support body 312 or the cylinder 313, or a pattern processed on the surface of the support body 312 or the cylinder 313.
[0060] like Fig. 9 As shown, in the illustrated embodiment, four indicator marks 321 are provided on the decorative sheet 322, and the four indicator marks 321 are arranged at intervals along the circumference of the decorative sheet 322, respectively representing four different gears of the cooking device. For example, "off gear", "gear 1", "gear 2", and "gear 3". The range of the four indicator marks 321 arranged along the circumference of the decorative sheet 322 needs to be smaller than the maximum angle at which the knob 31 can rotate relative to the decorative member 32, so as to ensure that the pointer 311 on the knob 31 can indicate the indicator mark 321 corresponding to the required gear. Of course, in other embodiments, the indicator marks 321 on the decorative sheet 322 can also be set to two, three, five or more as needed, and multiple indicator marks 321 are arranged at intervals along the circumference of the decorative sheet 322, as long as the pointer 311 on the knob 31 can indicate all the indicator marks 321 during the rotation process.
[0061] like Figure 6 As shown, in the illustrated embodiment, there are two fixing parts 324, and the two fixing parts 324 are arranged on both sides of the decorative sheet 322. The avoidance holes 3121 are arranged one-to-one with the fixing parts 324 and are set as arc-shaped holes. At this time, the maximum angle at which the knob 31 can rotate is less than 180°, and the range of the circumferential arrangement of the multiple indicator marks 321 along the decorative sheet 322 is also within 180°. The two fixing parts 324 can ensure the stability and reliability of the connection between the decorative part 32 and the outer shell 10, and the relative arrangement of the two fixing parts 324 makes the corresponding central angle of the arc-shaped hole as large as possible, so that the angle of rotation of the knob 31 is also as large as possible, so as to facilitate user adjustment.
[0062] Of course, in other embodiments, under the condition that the decorative piece 32 is reliably connected to the outer shell 10, the number of the fixing part 324 can also be one, and the avoidance hole 3121 can also be set to one. Alternatively, the number of the fixing parts 324 can also be three, four or more, and the multiple fixing parts 324 are arranged at intervals along the circumference of the decorative piece 322, and the avoidance holes 3121 can be arranged one-to-one with the fixing parts 324, or two or more fixing parts 324 can correspond to one avoidance hole 3121. As long as it is ensured that each fixing part 324 can slide a certain distance in the avoidance hole 3121, so that the knob 31 can rotate a certain angle relative to the decorative piece 32 to achieve the gear adjustment of the cooking appliance, the embodiment of the utility model does not make specific restrictions here.
[0063] like Figure 3 , Figure 4 and Fig.10 As shown, the fixing portion 324 is a claw, and a slot 121 is provided on the outer shell 10, and the claw is clamped in the slot 121. The clamping fit between the claw and the slot 121 can ensure the reliability of the connection between the decorative element 32 and the outer shell 10, and facilitate the installation and removal of the decorative element 32. In addition, the slot 121 can also limit the position of the decorative element 32 to prevent the decorative element 32 from sliding along the axial direction of the knob assembly 30.
[0064] like Figures 4 to 5 As shown, in the illustrated embodiment, the outer shell 10 is further provided with a ring rib 12 located outside the assembly hole 11, and the clamping groove 121 is provided on the ring rib 12. The ring rib 12 can limit the position of the decorative element 32, prevent the decorative element 32 from sliding radially along the knob assembly 30 and affecting the normal rotation of the knob 31, and can also further facilitate the user to install the decorative element 32.
[0065] Furthermore, the annular rib 12 is provided with a first reinforcing rib 13, and the first reinforcing rib 13 and the wall of the annular rib 12 are combined to form a guide groove 14 connected to the clamping groove 121. The first reinforcing rib 13 can improve the strength of the annular rib 12, and prevent the annular rib 12 from being deformed or broken after long-term use, thereby ensuring the stability of the knob assembly 30 and extending the service life of the outer shell 10 and the knob assembly 30. At the same time, the first reinforcing rib 13 can also limit the position of the decorative part 32, and prevent the decorative part 32 from rotating with the knob 31 relative to the annular rib 12, and the guide groove 14 can also guide the claw, further facilitating the user to align and install the decorative part 32.
[0066] In another embodiment, the card slot 121 may also be directly provided on the outer shell 10. Alternatively, in other embodiments, the fixing portion 324 and the outer shell 10 may also be fixedly connected by screws, plugging, or other methods, as long as the reliability of the connection between the decorative member 32 and the outer shell 10 can be ensured and the normal rotation of the knob 31 will not be affected, and the embodiment of the utility model does not make any specific restrictions here.
[0067] like Figure 6 and Fig.11 As shown, a convex rib 323 is provided on one side of the decorative sheet 322 facing the assembly groove 314, and the convex rib 323 is arranged at intervals along the circumference of the decorative sheet 322. The convex rib 323 can reduce the contact area between the decorative sheet 322 and the support body 312, reduce the friction force of the knob 31 during the rotation process, make the user more labor-saving when adjusting the knob 31, and also can reduce the wear of the knob 31 and the decorative member 32, and extend the service life of the knob assembly 30.
[0068] Among them, the rib 323 can be in a hemispherical, strip-shaped, wavy shape, etc., and the cross-section of the strip-shaped protrusion can be a regular or irregular shape such as a triangle or a square, so as to replace the surface contact between the decorative sheet 322 and the support body 312 with point contact or line contact, effectively reducing the friction between the knob 31 and the decorative part 32.
[0069] Furthermore, the decorative sheet 322, the rib 323 and the fixing portion 324 can be integrally formed to ensure the stability and reliability of the connection between the parts and facilitate the processing of the decorative piece 32. The indicator mark 321 can be a protrusion integrally convexly provided on the decorative sheet 322, a groove provided on the decorative sheet 322, or a pattern processed on the surface of the decorative sheet 322.
[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0071] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
