[0002] The control structures of cooking appliances disclosed in the related prior art, such as rice cookers, electric pressure cookers, etc., are mainly divided into three categories: touch type, button type and knob type. Among them, the knob type structure is widely used in cooking appliances due to its simple structure, convenient operation and easy maintenance.

[0003] The motor timer knob is used in the cooking appliance with a knob structure. There is an indicator icon on the motor timer knob, and the time pattern corresponding to the function is silk-screened on the panel. When the user rotates the knob so that the indicator icon points to the time pattern on the panel, it indicates the currently selected function time.

[0004] The position of the knob is indicated only by the indicator icon on the motor timer knob. For elderly users with poor eyesight, selecting the rotation position of the knob requires careful observation of the desired position by the panel, which makes it inconvenient to observe and confirm the product status during cooking. This panel display is not intuitive, and elderly users need to control the food they are cooking by themselves. It is easy for them to undercook the food or overcook the food due to improper operation. Utility Model Content

[0034] like Figure 1 and Figure 2 and Figure 4As shown, the present application provides a panel assembly of a cooking utensil, and the first embodiment of the panel assembly of the cooking utensil includes: a circuit board 10, a panel 20, a knob 30 and a transparent sticker 40. An encoder 11 and a plurality of first indicator lights 12 are provided on the circuit board 10. The panel 20 is located on the side of the circuit board 10 where the first indicator lights 12 are provided, and a plurality of first avoidance holes 21 corresponding to the plurality of first indicator lights 12 are provided on the panel 20. The knob 30 is located on the side of the panel 20 away from the circuit board 10, and a part of the knob 30 passes through the panel 20 and is connected to the encoder 11. When the knob 30 is rotated to different working positions, the first indicator lights 12 at the corresponding position light up. The transparent sticker 40 is arranged on a side of the panel 20 away from the circuit board 10 and covers all the first avoidance holes 21. The transparent sticker 40 is provided with a second avoidance hole 22 for the knob 30 to pass through. Different first time marks 41 are arranged on the transparent sticker 40. The different first time marks 41 are surrounded by the knob 30, and the different first time marks 41 correspond one by one to the multiple first indicator lights 12.

[0035] By applying the technical solution of the first embodiment, when the knob 30 is rotated to any working position, the first indicator light 12 corresponding to the current working position is turned on, and the current first indicator light 12 illuminates the current first time mark 41 on the transparent sticker 40 through the corresponding first avoidance hole 21, which can intuitively display the current first time mark 41, making it convenient for the user to observe and confirm the rotation position of the knob 30. Therefore, the technical solution of the first embodiment effectively solves the problem of non-intuitive panel display in the related art. The transparent sticker corresponds to all the first avoidance holes 21 and is not transparent in other areas.

[0036] When the knob 30 is rotated to a different working position, the first indicator light 12 at the corresponding position lights up, indicating that the first indicator light corresponds to a different cooking function or cooking mode, which directly reflects the improvement of the human-computer interaction user experience. The different first time marks 41 increase in length clockwise, which is also a point of improving the experience, and also imitates a mechanical panel, so there is no need to look closely to confirm the selected gear or function.

[0037] Moreover, on the one hand, setting the above-mentioned different first time marks 41 on the transparent sticker 40 is simpler, more convenient and lower in cost. On the other hand, the transparent sticker 40 covers the setting of all the first avoidance holes 21, blocks all the first avoidance holes 21 on the panel 20, prevents water or debris outside the cooking utensil from entering the first avoidance holes 21, and can also cover defects such as flow marks generated during the molding process of the panel 20, thereby improving the overall appearance of the panel assembly.

[0038] It should be noted that the circuit board 10 is preferably a PCB. In this embodiment, a cooking appliance with a pressure switch is used. The cooking appliance does not have a top temperature measurement and cannot realize different pressure controls for different functions. That is, the cooking appliance of this embodiment realizes cooking functions such as cooking rice, cooking porridge, and stewing soup. The pressure holding time corresponding to each cooking function is different. The pressure holding time is not fixed and has the ability to judge the amount, and can be automatically adjusted according to the amount of food in the pot.

[0039] Of course, in an embodiment not shown in the figure, the cooking appliance has a top temperature measurement, which can realize different pressure controls for different functions, that is, high-pressure cooking and low-pressure cooking.

[0040] In this embodiment, the cooking utensil can cook food with the lid closed or open. When the cooking utensil is closed to cook food, the time for maintaining pressure and heating the food is between 1 and 35 minutes. It should be further clarified that food can be cooked with the lid half open or open, and the heating time can be unlimited.

[0041] The above cooking modes include a keep warm mode, an open lid mode, and a pressure cooking mode. Among them, the pressure cooking mode includes multiple cooking functions, and the multiple cooking functions correspond to different pressure holding time gears. In a certain pressure holding time gear, the cooking appliance can adjust the pressure holding time within a certain range according to the detected amount of food. The food amount is detected by a known method, for example, by using a pot bottom temperature detection element to record the temperature rise rate during a certain period of the temperature rise stage to make a judgment.

[0042] In the related art, the motor timer knob of the mechanical electric pressure cooker uses an electric motor timer, which controls the cooking time of the mechanical electric pressure cooker. When the mechanical electric pressure cooker is needed to cook food, the electric motor timer is rotated, the cooking time of the food is selected, and the electric pressure cooker is powered on to start heating. When a certain pressure or temperature is reached in the electric pressure cooker, the electric motor timer starts to work. When the electric motor timer is working, it will inevitably make buzzing and clicking sounds due to the operation, working mechanism or electromagnetic interference of the electric motor timer itself. This noise will cause damage to the human auditory system, causing ear pain, tinnitus, hearing loss, and even anxiety and depression in severe cases.

[0043] In order to solve the above problems, in the first embodiment, the encoder 11 provided on the circuit board 10 has a cumulative counting function, which can realize accurate time intervals, and can also realize accurate measurement of a period of time to control the operation of the electric pressure cooker. It can also realize the functions of intelligent power-off and intelligent reminder of the electric pressure cooker through accurate time measurement of the timing counter. It can perfectly replace the electric motor timer and effectively eliminate the harmful noise generated during the operation of the electric motor timer. When the cooking appliance realizes the cooking function, unlike the mechanical knob, the duration is not strictly determined, and the relative duration can be automatically adjusted according to the amount of food. For example, if it is set to 35 minutes, it may also slightly exceed the 35-minute pressure holding time.

[0044] like Figure 1 and Figure 2 As shown, different function marks 42 are also provided on the transparent sticker 40, and the different function marks 42 are arranged around the knob 30. The different function marks 42 are used to help the user select different functions, so that the user can operate the cooking appliance more conveniently and ensure that the food can be accurately heated and cooked, thereby achieving different cooking effects.

[0045] like Figure 1 and Figure 2 As shown, different function identifiers 42 correspond to multiple first indicator lights 12. When the knob 30 is rotated to any working position, the first indicator light 12 corresponding to the current working position lights up, and the current first indicator light 12 illuminates the current function identifier 42 on the transparent sticker 40 through the corresponding first avoidance hole 21, which can intuitively display the current function identifier 42, making it convenient for the user to observe and confirm the rotation position of the knob 30.

[0046] Specifically, different first time marks 41 are arranged in a clockwise direction from small to large numbers, such as "0" ("off"), "5", "10", "15", "20", "25", "30", "35". In this way, the method of rotating the knob to make a selection simplifies the user's selection, and the arrangement of different function marks 42 is that the function options of the more difficult to cook food are placed at the end, which is convenient for the user to control the rotation angle of the knob or the position of the indicator light according to the type of food to be cooked.

[0047] like Figure 1 and Figure 2 As shown, in order to facilitate the user to observe and confirm that the knob 30 is rotated to the initial position, one of the first time marks 41 is an initial mark, and the initial mark is "start" or "cancel" or "start / cancel" or "off" or "0". In order to facilitate the user to observe and confirm the rotational position of the knob 30, multiple first time marks 41 are digital marks.

[0048] like Figure 1 and Figure 2 As shown, one of the first time marks 41 is a graphic mark. When the knob 30 is rotated to the open cover gear, the first indicator light 12 corresponding to the open cover gear is lit, and the cooking appliance executes the open cover mode. At this time, the cooking appliance can be completely covered (the cover teeth are locked) without heating, or half-closed (only covered, the cover teeth are not locked) or open to cook food. When the cooking appliance opens the cover to cook food, it continues to heat and boil, and the length of time for heating food is not limited by time. The graphic mark can be round, square or diamond.

[0049] like Figure 1 and Figure 2 As shown, in order to inform the user that the knob 30 can be turned counterclockwise, a counterclockwise indicating arrow mark is also provided on the transparent sticker 40.

[0050] In order to avoid the situation that the electric pressure cooker starts heating even without any operation after being plugged in, which brings great safety risks and confusion to the user. If there is no separate power switch on the pot body, the power cord needs to be unplugged to stop heating. In the first embodiment, when the knob 30 is rotated counterclockwise to the working position of "start" or "cancel" or "start / cancel" or "off" or "0", the cooking appliance can shut down or cancel the current heating work, and the cooking appliance will not start heating, reducing safety risks and confusion.

[0051] like Figure 1 and Figure 2 As shown, the circuit board 10 is also provided with a second indicator light 13, the panel 20 is also provided with a third avoidance hole 23 for avoiding the second indicator light 13, the translucent sticker 40 covers the third avoidance hole 23, and the translucent sticker 40 is also provided with a keep-warm mark 43. The circuit board 10 is provided with a keep-warm switch 14 at a position corresponding to the keep-warm mark 43, and the panel 20 is provided with a keep-warm button 24 at a portion between the keep-warm mark 43 and the keep-warm switch 14. When the keep-warm button 24 is operated, the keep-warm switch 14 is driven to control the second indicator light 13 to light up, and the cooking appliance executes the keep-warm mode. In this process, the second indicator light 13 lights up and can illuminate the translucent sticker 40 through the third avoidance hole 23, so that the second indicator light 13 can be directly noticed and observed, which is convenient for the user to observe and confirm the rotation position of the knob 30.

[0052] The transparent sticker 40 covers the third avoidance hole 23, blocks the third avoidance hole 23 on the panel 20, and prevents water or debris outside the cooking utensil from entering the third avoidance hole 23. The transparent sticker 40 is commonly made of PC or PET, and the second most preferred material is PVC, which corresponds to polycarbonate, polyethylene terephthalate, and polyvinyl chloride in Chinese. The transparent sticker corresponds to all third avoidance holes 23 being transparent, and other areas are not transparent.

[0053] In the keep warm mode, the cooking appliance is generally kept warm for a long time, maintaining the temperature in the pot at 70 degrees Celsius, and the power is low-power intermittent heating.

[0054] In other embodiments, the cooking appliance does not have a keep warm button, but a keep warm gear is set in the encoder. When the knob 30 is rotated to the keep warm gear, the second indicator light 13 corresponding to the keep warm gear is turned on, and the cooking appliance executes the keep warm mode. This solution without an additional keep warm button or a small light panel highlights the minimalist design concept, and the usage method is similar to that of a mechanical electric pressure cooker, and the human-computer interaction is more friendly.

[0055] like Figure 3 As shown, in the second embodiment of the panel assembly of the cooking utensil, in order to facilitate the cooking utensil to realize the reservation function, the difference from the first embodiment of the panel assembly of the cooking utensil is that the circuit board 10 is also provided with a reservation switch 15 and a plurality of third indicator lights 16. The panel 20 is also provided with a plurality of fourth avoidance holes 25 for avoiding the plurality of third indicator lights 16, and the transparent sticker 40 covers all the fourth avoidance holes 25. The transparent sticker 40 is also provided with a reservation mark 44 and different second time marks 45, and the different second time marks 45 correspond to the plurality of third indicator lights 16 one by one. The reservation mark 44 corresponds to the reservation switch 15. The portion of the panel 20 located between the reservation mark 44 and the reservation switch 15 is provided with a reservation button 26. When the reservation button 26 is operated, the reservation switch 15 is driven to control the different third indicator lights 16 to light up, and the cooking utensil can execute different reservation times. In this process, the third indicator lights 16 light up and can illuminate the transparent sticker 40 through the fourth avoidance holes 25, so that the third indicator lights 16 can be directly noticed and observed, which is convenient for the user to observe and confirm the rotation position of the knob 30. In addition, the transparent sticker 40 covers all the fourth avoidance holes 25 , blocks all the fourth avoidance holes 25 on the panel 20 , and prevents water or debris outside the cooking utensil from entering the fourth avoidance holes 25 .

[0056] It should be noted that the one-to-one correspondence between different second time identifiers 45 and multiple third indicator lights 16 means that the third indicator lights 16 are behind or below the second time identifier 45, that is, in the first mode, the third indicator lights 16 can illuminate the corresponding second time identifier through the fourth avoidance hole; in the second mode, the third indicator lights 16 do not illuminate the corresponding second time identifier, and on the panel, multiple third indicator lights 16 are distributed at the scales below different second time identifiers. The second mode is specifically adopted in this embodiment.

[0057] like Figure 3As shown, in the second embodiment, different second time marks 45 are arranged around the side of the reservation mark 44 away from the knob 30. In this way, the user can notice and observe the second time marks 45 around the reservation mark 44 when operating the reservation button 26. Specifically, the different second time marks 45 are arranged in a clockwise direction from small to large numbers, such as "2", "4", "6", "9", "12", and "24".

[0058] like Figure 1 and Figure 2 As shown, the panel assembly of the cooking appliance further includes a buzzer connected to the circuit board 10. When the knob 30 is rotated to any working gear, the buzzer emits a sound. When the knob 30 is rotated to any working gear, the first indicator light 12 corresponding to the current working gear is lit, and the buzzer emits a sound to remind the user, so that the user knows that the cooking appliance executes the cooking mode corresponding to the current working gear.

[0059] like Figure 1 and Figure 2 As shown, in order to facilitate processing and reduce production costs, the side of the knob 30 is an operating surface 31, and the end surface of the knob 30 is a non-marking surface 32. A silver-white metal brushed texture decorative plate is provided on the non-marking surface 32.

[0060] like Figure 1 and Figure 2 As shown, in order to simulate the mechanical electric pressure cooker for the user and adapt to the user's habit of using the mechanical electric pressure cooker, the transparent sticker 40 includes a rectangular area 46 and an annular area 47 located in the rectangular area 46, the annular area 47 is located outside the second avoidance hole 22, and the different first time marks 41 are all set on the annular area 47. The four corners of the rectangular area 46 include right angles and / or rounded corners.

[0061] like Figure 1 and Figure 2 As shown, in order to meet the user's ease of use requirements, the ratio of the outer diameter of the annular area 47 to the outer diameter of the knob 30 is in the range of 1.37 to 1.89, and the ratio of the width of the rectangular area 46 to the outer diameter of the knob 30 is in the range of 2.1 to 3.64. The outer diameter of the knob is in the range of 26.5mm to 52.6mm, preferably 26.5mm, 40mm, 48.5mm or 52.6mm. In this way, the larger the diameter of the outer ring of the knob 30, the more conducive it is to increase the force arm, and the more labor-saving it is, so that it is easier for users to find the knob 30 and operate it. Compared with the buttons in the related operation technology, operating the knob 30 is more friendly to the aging finger joints of the elderly.

[0062] like Figure 1 and Figure 2As shown, in order to effectively distinguish the first time mark 41 and the function mark 42 and avoid confusion between the position of the first time mark 41 and the position of the function mark 42, the transparent sticker 40 includes a rectangular area 46 and an annular area 47 located in the rectangular area 46, the annular area 47 is located outside the second avoidance hole 22, different first time marks 41 are all set on the annular area 47, and different function marks 42 are all set on the rectangular area 46. Different first time marks 41 are arranged according to the circumference for better memory.

[0063] like Figure 1 and Figure 2 As shown, in order to facilitate the user to directly observe the current function identifier 42 when observing the current first time identifier 41 when operating the knob, a plurality of indicator lines 461 are also provided on the rectangular area 46 , and each first time identifier 41 corresponds to each function identifier 42 through an indicator line 461 .

[0064] The present application also provides a cooking utensil, such as Figure 1 , Figure 2 and Figure 4 As shown, the cooking appliance includes a pot body 50, a cover body and a panel assembly arranged on the pot body 50. The panel assembly is the panel assembly of the above-mentioned cooking appliance. Since the panel assembly of the above-mentioned cooking appliance can solve the problem of non-intuitive panel display in the related art, the cooking appliance including the panel assembly can solve the same technical problem. The cooking appliance is an electric pressure cooker, a steamer, an oven or a multi-function cooker.

[0065] Of course, in other embodiments, the panel assembly is disposed on the cover body.

[0066] like Figure 1 , Figure 2 and Figure 4 As shown, in order to solve the problem of user safety, the cooking appliance further includes a power board 52 and a lid opening and closing position detection device, the power board 52 is arranged in the pot body 50, and the lid opening and closing position detection device includes a lid opening trigger and a sensing member 51 that can sense and cooperate with the lid opening trigger. The sensing member 51 is connected to the power board 52, the lid opening trigger is arranged on the cover body, and the sensing member 51 is arranged on the pot body 50. When the cover body is closed on the pot body 50, the lid opening trigger and the sensing member 51 sense and cooperate, and when the cover body is opened from the pot body 50, the lid opening trigger and the sensing member 51 are disconnected.

[0067] The induction element 51 is an electronic reed switch, which solves the problem of installing a micro switch on the middle plate of the cooking utensil and provides a through hole, and avoids providing a protrusion, so that the middle plate of the cooking utensil is flat and the processing cost can be reduced. The corresponding lid opening trigger element is a magnetic element.

[0068] Of course, in other embodiments, the sensing element 51 is a micro switch, and the corresponding cover opening trigger element is a trigger rod.

[0069] The panel assembly is arranged on the outer shell of the pot body 50, and the MCU controller is arranged on the power board 52. The circuit board 10 is connected to the power board 52 and powered by the power board 52. A temperature sensing cup and a heating element 53 are arranged in the pot body 50, and both the temperature sensing cup and the heating element 53 are connected to the power board 52. The heating element 53 is preferably a heating plate or a heating wire. By rotating the knob, the digital signals of multiple working gears are transmitted to the MCU controller. The MCU controller receives the signal and drives multiple first indicator lights to light up, so that the user can intuitively feedback the current operation. The MCU controller needs to be programmed, that is, by writing and burning multiple digital signals input by the encoder to set different cooking times corresponding to different first time identifiers 41, which can be customized and meet the use requirements of the elderly or other groups in a targeted manner. Specifically, the MCU controller can judge the amount of rice water or food according to the heating temperature rise slope, and then adjust the pressure holding time of the electric pressure cooker. Thus, it provides users with a product that is intelligent and easy to operate. This solves the limitation that the mechanical electric pressure cooker in the related art cannot be expanded because it is a pure circuit control structure and is not equipped with the MCU controller of the present application.

[0070] In other embodiments, the sensing member 51 is disposed on the cover, and the lid-opening trigger member is disposed on the pot body 50 . When the cover is closed on the pot body 50 , the lid-opening trigger member and the sensing member 51 cooperate with each other by induction.

[0071] like Figure 1 , Figure 2 and Figure 4 As shown, in order to remind the user that the cooking appliance has the function of detecting whether the lid is opened or closed, a lid closing mark 48 and a lid opening mark 49 are also provided on the transparent sticker 40 of the panel assembly.

[0072] The inventors have found that the mechanical electric pressure cookers and electronic electric pressure cookers in the related art have the following problems:

[0073] The panel of a mechanical electric pressure cooker only has small menu text and prompt information about the cooking time, which is not easy to see clearly, and there is no lid opening and closing detection function.

[0074] There are many buttons on the panel of the electronic electric pressure cooker. For the elderly, it is not easy to find the required buttons, or they need to remember the location of commonly used buttons, which is inconvenient. Moreover, such buttons are not very friendly to the aging finger joints of the elderly. On another part of the electronic electric pressure cookers with knobs, the knobs and menu texts are arranged separately. When turning the knobs, they need to carefully check the dynamic menu texts, which is still inconvenient and the user experience is not good.

[0075] In order to solve the above problems and meet the goal of aging-friendly products, the panel assembly of the cooking appliance of the present application specifically meets the following requirements:

[0076] 1. To meet the safety goal of electric pressure cookers suitable for the elderly, in this embodiment, when the knob 30 is rotated counterclockwise to the working position of "start" or "cancel" or "start / cancel" or "off" or "0", the cooking appliance can execute the shutdown or cancel the current heating operation. The operation mode of turning on the heating set in this way conforms to the usage habits of users of mechanical electric pressure cookers. It is more convenient to cancel heating or change the cooking time (cooking function). The heating plate of the electric pressure cooker does not heat when it is plugged in, which has energy-saving effects. There is no need to plug and unplug the power cord, and the safety is better. In addition, a lid opening and closing detection device is set to detect whether the lid of the electric pressure cooker is in place and the lid is in place to prevent electric damage.

[0077] 2. To meet the functional objectives of the electric pressure cooker suitable for the elderly, in this embodiment, when the knob 30 is rotated to any working position, the first indicator light 12 corresponding to the current working position is lit, and the current first indicator light 12 illuminates the current first time mark 41 on the transparent sticker 40 through the corresponding first avoidance hole 21, and can intuitively display the current first time mark 41, which is convenient for the user to observe and confirm the rotation position of the knob 30, and meets the expected use requirements. When the knob 30 is rotated to any working position, the first indicator light 12 corresponding to the current working position is lit, and the buzzer sounds to remind the user, so that the user knows that the cooking appliance executes the cooking mode corresponding to the current working position, and the auditory ability partially replaces the visual ability.

[0078] 3. To meet the goal of ease of use of the electric pressure cooker suitable for the elderly, in this embodiment, the panel assembly has a simple structure and is easy to operate. Cooking operations can be completed with just one knob. It can rotate forward and reverse very smoothly, without the need for a gear feel, and is easy to use. The operation process feels comfortable, and it also avoids the problem that the buttons in the related technology are not very friendly to the aging finger joints of the elderly, thereby making the panel assembly lower in cost and more reliable.

[0079] 4. Meeting the compatibility goal of electric pressure cookers suitable for the elderly, the electric pressure cooker of this embodiment can not only meet the compatibility requirements of electric pressure cookers suitable for the elderly, but can also be used by other users.

[0080] Therefore, the setting of the electric pressure cooker of the present application takes into account the advantages of both mechanical electric pressure cookers and electronic electric pressure cookers. It not only takes into account the usage habits of the elderly, but also designs a simpler function menu than the electronic electric pressure cooker. That is, the internal structure of the electric pressure cooker of the present application improves the internal structure of the mechanical electric pressure cooker in the related technology, and the external structure of the electric pressure cooker of the present application improves the external structure of the electronic electric pressure cooker in the related technology.

[0081] 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.

[0082] 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.

[0083] 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.
