[0030] like Figures 1 to 3As shown, the present application provides an aging-friendly smart electric pressure cooker, and an embodiment of the aging-friendly smart electric pressure cooker includes: a pot body 50, a light board 10, an MCU controller, a panel 20, a knob 30 and a light-transmitting sticker 40. The light board 10 is arranged on the outside of the pot body 50, and an encoder 11 and a plurality of first indicator lights 12 are arranged on the light board 10, and no display screen is arranged on the light board. The MCU controller is arranged on the pot body 50, and the MCU controller is connected to the light board 10. The panel 20 is located on the side of the light board 10 where the first indicator light 12 is arranged. The knob 30 is located on the side of the panel 20 away from the light 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 gears, the MCU controller can control the corresponding first indicator light 12 to light up. When the knob 30 is rotated to different working gears, the first indicator light 12 at the corresponding position lights up, indicating that the first indicator light corresponds to different cooking functions or cooking modes, which directly reflects the improvement of the human-computer interaction experience of the elderly. The different first time marks 41 increase in length clockwise, which is also a point of improving the experience and also imitates the mechanical panel, so there is no need to look closely to confirm the selected gear or function.

[0031] The outer diameter of the knob is in the range of 26.5 mm to 52.6 mm. The light-transmitting sticker 40 is arranged on the side of the panel 20 away from the light board 10, and the light-transmitting sticker 40 is provided with a first avoidance hole 22 for the knob 30 to pass through. Different first time marks 41 are arranged on the light-transmitting sticker 40, and the different first time marks 41 are arranged outside the knob 30, and the different first time marks 41 correspond to the multiple first indicator lights 12 one by one.

[0032] By applying the technical solution of this embodiment, a display screen is not provided on the light board 10, and a plurality of first indicator lights 12 are also arranged outside the knob 30, replacing the prompt function of the display screen. Moreover, the space occupied by the plurality of first indicator lights 12 on the panel 20 is smaller than that of the display screen, and a larger outer ring diameter of the knob can be designed on the panel 20, such as in the range of 26.5 mm to 52.6 mm. In this way, the larger the diameter of the outer ring of the knob 30, the greater the force arm, and the more labor-saving it is, which is convenient for the elderly to hold and operate, and improves the hand feel. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that only a smaller-sized knob can be provided because the display screen occupies a large space on the panel.

[0033] It should also be emphasized that the technical solution of this application aims to break through the inherent ideas of product design in the industry and design intelligent small household appliances specifically for the elderly.

[0034] In this embodiment, the outer diameter of the knob is preferably 26.5 mm, 40 mm, 48.5 mm or 52.6 mm.

[0035] 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 selection of the elderly, 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 elderly to grasp the rotation angle of the knob or the position of the indicator light according to the type of food to be cooked.

[0036] In this embodiment, the aging-friendly smart electric pressure cooker can cook food with the lid closed or open. When the aging-friendly smart electric pressure cooker closes the lid to cook food, the time for maintaining pressure and heating 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 at this time.

[0037] In order to avoid the situation that after the electric pressure cooker is plugged in, the aging-friendly smart electric pressure cooker will start heating even if no operation is performed, which brings great safety hazards and doubts to the elderly. If there is no separate power switch on the pot body, the power cord needs to be unplugged to stop heating. 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 aging-friendly smart electric pressure cooker can execute the shutdown or cancel the current heating work, and the aging-friendly smart electric pressure cooker will not start heating, reducing safety hazards and doubts.

[0038] like Figure 2 and Figure 3 As shown, in order to simulate a mechanical electric pressure cooker and adapt to the habit of the elderly using mechanical electric pressure cookers, the light-transmitting sticker 40 includes an annular area 47, which is located outside the first avoidance hole 22, and different first time marks 41 are all set on the annular area 47.

[0039] like Figure 2 and Figure 3 As shown, in order to meet the ease of use requirements of the elderly, 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. In this way, the outer ring of the knob 30 is larger, which is convenient for the elderly to find the knob 30, and the operation of the knob 30 is more friendly to the aging finger joints of the elderly than the operation of the buttons in the related art.

[0040] like Figure 2 and Figure 3As shown, the light-transmitting sticker 40 includes a rectangular area 46 surrounding the outer side of the annular area 47, and different function labels 42 are also provided on the light-transmitting sticker 40, and the different function labels 42 are all provided on the rectangular area 46. Different function labels 42 are used to help the elderly select different functions, so that the elderly can more conveniently operate the aging-friendly smart electric pressure cooker, and ensure that the food can be accurately heated and cooked, thereby achieving different cooking effects.

[0041] The four corners of the rectangular area 46 include right angles and / or rounded corners.

[0042] like Figure 2 and Figure 3 As shown, in order to meet the ease of use requirements of the elderly, 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. In this way, the outer ring of the knob 30 is larger, which is convenient for the elderly to find the knob 30.

[0043] like Figure 2 and Figure 3 As shown, one of the first time marks 41 is an initial mark, which is "start" or "cancel" or "start / cancel" or "off" or "0"; wherein a plurality of first time marks 41 are digital marks. In order to facilitate the elderly to observe and confirm the rotational position of the knob 30, a plurality of first time marks 41 are digital marks.

[0044] like Figure 2 and Figure 3 As shown, one of the first time marks 41 is a graphic mark, and the graphic mark corresponds to the open cover gear. When the knob 30 is rotated to the open cover gear, the first indicator light 12 corresponding to the open cover gear is turned on, and the aging-friendly smart electric pressure cooker executes the open cover mode. At this time, the aging-friendly smart electric pressure cooker 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 aging-friendly smart electric pressure cooker opens the lid 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.

[0045] like Figure 2 and Figure 3 As shown, in order to inform the elderly that they can turn the knob 30 counterclockwise, a counterclockwise arrow mark is also provided on the light-transmitting sticker 40.

[0046] like Figure 2 and Figure 3As shown, the panel 20 is provided with a plurality of second avoidance holes 21 corresponding to the plurality of 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 is turned on, and the current first indicator light 12 illuminates the current first time mark 41 on the light-transmitting sticker 40 through the corresponding second avoidance holes 21, which can intuitively display the current first time mark 41, making it easier for the elderly to observe and confirm the rotation position of the knob 30. The light-transmitting sticker is light-transmitting corresponding to all the second avoidance holes 21, and other areas are not light-transmitting.

[0047] Moreover, on the one hand, setting the above-mentioned different first time marks 41 on the light-transmitting sticker 40 is simpler, more convenient and lower in cost. On the other hand, the light-transmitting sticker 40 covers the setting of all the second avoidance holes 21, blocks all the second avoidance holes 21 on the panel 20, prevents water or debris from the outside of the aging-friendly smart electric pressure cooker from entering the second avoidance holes 21, and can also block defects such as flow marks generated during the molding process of the panel 20, thereby improving the overall appearance of the panel assembly.

[0048] It should be noted that the light board 10 is preferably a PCB. In this embodiment, an aging-friendly smart electric pressure cooker with a pressure switch is used. The aging-friendly smart electric pressure cooker does not have a top temperature measurement and cannot achieve different pressure controls for different functions. That is, the aging-friendly smart electric pressure cooker of this embodiment realizes cooking functions such as cooking rice, cooking porridge, and stewing soup, and each cooking function corresponds to a different pressure holding time. 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.

[0049] Of course, in an embodiment not shown in the figure, the aging-friendly smart electric pressure cooker has top temperature measurement, which can realize different pressure controls for different functions, that is, high-pressure cooking and low-pressure cooking.

[0050] The above-mentioned cooking modes include keep warm mode, open lid mode, and pressure cooking mode. Among them, in the keep warm mode, the insulation of the aging-friendly smart electric pressure cooker is generally long-term insulation, maintaining the temperature in the pot at 70 degrees Celsius, and the power is low-power intermittent heating. The pressure cooking mode includes multiple cooking functions, and multiple cooking functions correspond to different pressure-holding time gears. In a certain pressure-holding time gear, the aging-friendly smart electric pressure cooker can adjust the pressure-holding time within a certain range according to the detected amount of food. The food amount is detected using a known method, for example, by using the temperature detection element at the bottom of the pot to record the heating rate during a certain period of the heating stage to make a judgment.

[0051] 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.

[0052] In order to solve the above problems, in this embodiment, the encoder 11 provided on the light 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 aging-friendly smart electric pressure cooker 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.

[0053] like Figure 2 and Figure 3 As shown, the light 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, and the light-transmitting sticker 40 is also provided with a heat preservation mark 43. The light board 10 is provided with a heat preservation switch 14 at the position corresponding to the heat preservation mark 43, and the panel 20 is provided with a heat preservation button 24 at the portion between the heat preservation mark 43 and the heat preservation switch 14. In this process, the second indicator light 13 is lit up and can illuminate the light-transmitting 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 elderly to observe and confirm the rotation position of the knob 30. And the light-transmitting sticker 40 covers the setting of the third avoidance hole 23, blocks the third avoidance hole 23 on the panel 20, and prevents water or debris outside the aging-friendly smart electric pressure cooker from entering the third avoidance hole 23. The common material of the light-transmitting sticker 40 is PC or PET, and the second preferred is PVC, and the corresponding Chinese is polycarbonate, polyethylene terephthalate, and polyvinyl chloride. The light-transmitting sticker is light-transmitting in all the third avoidance holes 23, and is light-impermeable in other areas.

[0054] like Figure 2 and Figure 3As shown, the different function marks 42 located on both sides of the knob 30 are arranged at intervals along the length direction of the rectangular area 46. In order to facilitate the elderly to directly observe the current function mark 42 when observing the current first time mark 41 when operating the knob, a plurality of indicator lines 461 are also provided on the rectangular area 46, and each first time mark 41 corresponds to each function mark 42 through the indicator line 461. In order to facilitate processing and positioning, a ring line 48 is provided on the rectangular area 46, and the ring area 47 is located within the ring line 48.

[0055] like Figure 2 and Figure 3 As shown, the light board 10 is also provided with a reservation switch 15 and a plurality of third indicator lights 16, and the panel 20 is also provided with a plurality of fourth avoidance holes 25 for avoiding the plurality of third indicator lights 16. The light-transmitting 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, and the reservation mark 44 corresponds to the reservation switch 15. The portion of the panel 20 between the reservation mark 44 and the reservation switch 15 is provided with a reservation button 26. When the reservation button is operated, the reservation switch is driven to control different reservation indicator lights to light up, and the aging-friendly smart electric pressure cooker can execute different reservation times. In this process, the reservation indicator light can illuminate the light-transmitting sticker 40 through the fifth avoidance hole, and the reservation indicator light can be directly noticed and observed, which is convenient for the elderly to observe and confirm the rotation position of the knob 30. And the light-transmitting sticker 40 covers the setting of all the fifth avoidance holes, and blocks all the fifth avoidance holes on the panel 20 to prevent water or debris outside the aging-friendly smart electric pressure cooker from entering the fifth avoidance hole.

[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] In this 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 elderly 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] In order to facilitate processing and reduce production costs, the side surface 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.

[0059] like Figure 2 and Figure 3 As shown, the aging-friendly smart electric pressure cooker also includes a power board 52 arranged on the pot body 50, the power board 52 is connected to the light board 10, the MCU controller is connected to the power board 52, and the aging-friendly smart electric pressure cooker also includes a buzzer 17 connected to the light board 10. When the knob 30 is rotated to any working gear, the buzzer makes 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 makes a sound to remind the elderly, so that the elderly know that the aging-friendly smart electric pressure cooker executes the cooking mode corresponding to the current working gear.

[0060] like Figures 1 to 3 As shown, the aging-friendly smart electric pressure cooker also includes a cover body arranged on the pot body 50, and the aging-friendly smart electric pressure cooker also includes a cover opening and closing position detection device, which includes a cover opening trigger and a sensing member 51 that can sense and cooperate with the cover opening trigger, the sensing member 51 is connected to the power board 52, the cover 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 cover opening trigger and the sensing member 51 are sensed and cooperated, and when the cover body is opened from the pot body 50, the cover opening trigger and the sensing member 51 are disconnected.

[0061] In other embodiments, the sensor 51 is disposed on the lid, and the lid-opening trigger is disposed on the pot body 50 .

[0062] The induction part is an electronic reed switch, which solves the problem of installing a micro switch on the middle plate of the smart electric pressure cooker for the elderly and avoids the need for protrusions, making the middle plate of the smart electric pressure cooker for the elderly smooth and reducing processing costs. The corresponding lid opening trigger is a magnetic part.

[0063] Of course, in other embodiments, the sensing element is a micro switch, and the corresponding cover opening trigger element is a trigger rod.

[0064] The light 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 provided 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 elderly can be intuitively fed back 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. This provides the elderly with a product that is intelligent and easy to operate. This solves the limitation that the mechanical electric pressure cooker in the related art is a pure circuit control structure, and it is not equipped with the MCU controller of this application, and the function cannot be expanded.

[0065] The inventors have found that the mechanical electric pressure cookers and electronic electric pressure cookers in the related art have the following problems:

[0066] 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.

[0067] 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 elderly's aging finger joints. On another part of the electronic electric pressure cookers with knobs, the knobs and menu texts are arranged separately. When turning the knobs, you need to carefully check the dynamic menu texts, which is still inconvenient and the elderly have a poor experience.

[0068] In order to solve the above problems and meet the goal of aging-friendly products, the panel assembly of the aging-friendly smart electric pressure cooker of the present application specifically meets the following requirements, wherein at least a light-transmitting sticker 40, a knob 30, a panel 20, an MCU controller, and a light board 10 constitute the panel assembly:

[0069] 1. To meet the safety goals of the electric pressure cooker 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 smart electric pressure cooker suitable for the elderly can execute the shutdown or cancel the current heating work. The operation mode of turning on the heating set in this way conforms to the usage habits of the elderly of mechanical electric pressure cookers. It is more convenient to cancel the heating or change the cooking time. 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 injury.

[0070] 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 turned on, and the current first indicator light 12 illuminates the current first time mark 41 on the light-transmitting sticker 40 through the corresponding second avoidance hole 21, which can intuitively display the current first time mark 41, making it convenient for the elderly to observe and confirm the rotation position of the knob 30, and meeting 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 turned on, and the buzzer sounds to remind the elderly, so that the elderly know that the smart electric pressure cooker suitable for the elderly executes the cooking mode corresponding to the current working position, and the auditory ability partially replaces the visual ability.

[0071] 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. It is easy to use and feels comfortable during the operation. 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.

[0072] 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.

[0073] 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.

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.

[0075] 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.

[0076] 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.
