Detailed Description
The following further description of the present invention, in order to facilitate understanding of those skilled in the art, is provided in conjunction with the accompanying drawings and is not intended to limit the scope of the present invention.
In order to achieve the above object, the present invention provides a pot body recognition device 1, as shown in fig. 1 and 2, comprising: and a main control chip 11.
The main control chip 11 is used for identifying the type of the pot body according to the height of the pot body; wherein, the type of the pan body is corresponding to the height of the pan body. The height of the pan body refers to the height of the pan body above the pan body heating system.
In the embodiment of the invention, for the multifunctional cooking device, in order to facilitate the use of different functions by a user, the pot body placed in the cooking device can be automatically identified, so that the identified pot body can remind the user of which function should be adopted. To achieve this, a main control chip 11 may be added to the cooking device, and the main control chip 11 may identify the type of the pot body through the height of the pot body placed in the cooking device. Specifically, the main control chip 11 identifies the type of the pan body according to the corresponding relationship between the type of the pan body stored in the chip and the height of the pan body. It should be noted that, in the embodiment of the present invention, the one-to-one correspondence relationship between the type of the pot body and the height of the pot body needs to be preset and stored in the main control chip 11. In addition, the main control chip 11 may adopt any programmable control chip, for example, a digital signal processing DSP, a field programmable gate array FPGA, or the like, and is not limited to a specific model. The specific implementation form of the main control chip 11 may be an existing integrated control chip, control unit or control device in the cooking device, or may be an additionally added integrated control chip, control unit or control device, and the like, and the specific implementation form of the main control chip 11 is not limited herein, and any control chip, control unit or control device capable of implementing the pan body identification scheme of the embodiment of the present invention is within the protection scope of the embodiment of the present invention.
In the embodiment of the invention, before the main control chip 11 identifies the type of the pan body according to the height of the pan body, the height of the pan body needs to be identified, and the method can be specifically realized by the following two schemes.
Scheme one, detect pot body height through predetermined pot body position detection device
Optionally, the pot body identification device further comprises: a pot body position detection device 12. As shown in fig. 3 and 4.
And the pot body position detection device 12 is used for detecting the height of the pot body.
In the embodiment of the present invention, the pot position detection device 12 may be arranged on the cooking device 3 in advance, and the specific arrangement position is not limited, and the arrangement position may be defined according to the specific type of the pot position detection device 12 and different application scenarios.
Alternatively, the pot position detecting device 12 may include: reed switches 121, micro switches 122 or infrared pair transistors 123.
Reed switch 121, micro switch 122 or infrared pair tube 123 are installed at the handle, bottom or side of the inner side of the casing of cooking device 3 (or the inner wall of cavity 32 for accommodating pot 31); wherein, when the pot body position detection device 12 comprises the reed pipe 121, the pot body 31 further comprises a magnetic device 121-1.
In the embodiment of the present invention, the pot position detecting device 12 may include: a reed switch 121. The reed switch (reed switch) is also called reed switch or magnetic reed switch, is a special magnetic-sensitive switch, and is the main part of reed relay and proximity switch. The dry reed tube usually has two metal reed contacts made of soft magnetic material and disconnected when there is no magnetism, and some have a third reed as a normally closed contact. These reed contacts are enclosed in a glass tube filled with an inert gas (e.g., nitrogen, helium, etc.) or vacuum, and the parallel enclosed reed ends in the glass tube overlap and are either gapped or in contact with each other to form normally open or normally closed contacts of the switch. The reed switch has simple operation principle, two pieces of magnetizable reeds overlapped with each other at the end points are sealed in a glass tube, the distance between the two reeds is only about a few microns, the glass tube is filled with high-purity inert gas, when the reed switch is not operated, the two reeds are not contacted, an external magnetic field enables the positions near the end points of the two reeds to generate different polarities, and as a result, the two reeds with different polarities attract each other and are closed. The technology can be used for manufacturing a switching assembly with very small size and volume, and has very high switching speed and very excellent reliability. The orientation and direction of the permanent magnet determines when and how many times the switch is turned on and off.
In the embodiment of the present invention, when the reed pipe 121 is used as the pot position detecting device 12, a plurality of reed pipes 121 may be disposed from top to bottom on the inner wall of the cavity 32 of the cooking device 3 for accommodating the pot body 31, and a magnetic device 121-1 (e.g., a magnet) may be mounted on the outer wall of the pot body 31, for example, on the lower portion of the outer wall, as shown in fig. 5. When the magnetic device 121-1 is located at the position of the reed switch 121, the main control chip 11 determines the position of the reed switch 121 as the height of the pot 31. In another embodiment, a plurality of reed pipes 121 can be further disposed on the outer wall of the pot 31 of the cooking device 3 from top to bottom, and a magnetic device 121-1 can be disposed on the inner wall (e.g. at the handle or at the middle upper part) of the cavity 32 for accommodating the pot 31, as shown in fig. 6. In the process that the pot body 31 is placed in the cavity 32 containing the pot body 31 from top to bottom, the magnetic device 121-1 sequentially passes through the reed pipes 121 arranged from top to bottom, and the height corresponding to the last reed pipe 121 passing through can be determined as the height of the pot body 31. The above descriptions are only two specific embodiments of the present invention, and other installation manners may be adopted in other embodiments, and the specific installation form and the installation number are not limited herein.
In the embodiment of the present invention, the pot position detecting device 12 may further include: a microswitch 122. The micro switch is a contact mechanism having a minute contact interval and a snap action mechanism and performing a switching operation with a predetermined stroke and a predetermined force. The outside of the switch is provided with a driving rod, and the distance between the contacts of the switch is smaller, so the microswitch is called a sensitive switch. The external mechanical force acts on the action reed through a transmission element (a press pin, a button, a lever, a roller and the like), and when the action reed is displaced to a critical point, instantaneous action is generated, so that a movable contact at the tail end of the action reed is quickly connected with or disconnected from a fixed contact. When the acting force on the transmission element is removed, the action reed generates reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is instantly finished. The micro switch has the advantages of small contact distance, short action stroke, small pressing power and quick on-off.
In the embodiment of the present invention, when the pot position detecting device 12 employs the micro switch 122, one or more micro switches 122 may be disposed on the inner wall of the cavity 32 of the cooking device 3 for accommodating the pot 31 from top to bottom, as shown in fig. 7. In the process that pot body 31 is placed into cavity 32 containing pot body 31 from top to bottom, pot body 31 will touch one or more action reeds of micro-switches 122 on the inner wall of cavity 32, and the height corresponding to the last micro-switch 122 touched can be determined as the height of pot body 31. Similarly, a plurality of micro switches 122 may be disposed on the outer wall of the pot body 31 of the cooking device 3 from top to bottom, and in the process that the pot body 31 is placed in the cavity 32 accommodating the pot body 31 from top to bottom, the inner wall of the cavity 32 accommodating the pot body 31 may touch one or more action reeds of the micro switches 122 on the outer wall of the pot body 31, and the height corresponding to the touched last micro switch 122 may be determined as the height of the pot body 31.
In the embodiment of the present invention, the pot position detecting device 12 may further include: and an infrared pair of transistors 123. The infrared pair tube comprises an infrared transmitting tube and a photosensitive receiving tube. The infrared emission tube is a luminous body consisting of infrared light emitting diode matrix, a PN junction is made of a material (common gallium arsenide) with high infrared radiation efficiency, current is injected to the PN junction by forward bias to excite infrared light, and the spectral power distribution of the infrared emission tube is 830-950 nm of central wavelength. The LED (Light Emitting Diode) shows a positive temperature coefficient, the temperature is higher when the current is larger, the current is higher when the temperature is higher, the power of the LED infrared lamp is related to the current magnitude, but when the forward current exceeds the maximum rated value, the emission power of the infrared lamp is reduced conversely. The photosensitive receiving tube is a PN junction with photosensitive characteristics, belongs to a photosensitive diode, and has unidirectional conductivity, so that reverse voltage needs to be applied during working. In the absence of light, there is very little saturated reverse leakage current (dark current). The photosensitive tube is not conducted at this time. When the light is irradiated, the saturated reverse leakage current is increased immediately to form a photocurrent, which is increased along with the change of the incident light intensity within a certain range.
In the embodiment of the present invention, when the pan body position detecting device 12 employs the pair of infrared tubes 123, one or more pair of infrared tubes 123 may be disposed on the inner wall of the cavity 32 of the cooking device 3 for accommodating the pan body 31 from top to bottom, and the infrared transmitting tube 123-1 and the photosensitive receiving tube 123-2 of the pair of infrared tubes 123 need to be installed at opposite positions on the same horizontal plane on the inner wall of the cavity 32, so that the photosensitive receiving tube 123-2 can directly receive the infrared light emitted from the infrared transmitting tube 123-1 when there is no object shielding, as shown in fig. 8. In the process that the pot body 31 is placed into the cavity 32 containing the pot body 31 from top to bottom, the pot body 31 forms a shielding body between the infrared transmitting tube 123-1 and the photosensitive receiving tube 123-2, so that the photosensitive receiving tube 123-2 is prevented from receiving infrared light emitted by the infrared transmitting tube 123-1, and the photosensitive receiving tube 123-2 is not conducted. The main control chip 11 can detect which infrared pair tube 123 the pan body reaches through the conduction and non-conduction of the photosensitive receiving tube 123-2, and the height corresponding to the last infrared pair tube 123 shielded by the pan body 31 can be determined as the height of the pan body 31.
The above description is an embodiment of detecting the height of the pan body by using a preset pan body position detection device in the embodiments of the present invention, and it should be noted that the above description is only a plurality of specific embodiments of the present invention, and in other embodiments, other pan body position detection devices may be used to detect the height of the pan body.
Scheme two, the height of the pot body is detected through the heating power of the pot body heating system
Optionally, the cooking device 3 where the pot body recognition device 1 is located includes a pot body 31 and a pot body heating system 33, and the pot body heating system 33 adopts an electromagnetic heating mode for heating; the main control chip 11 is connected with the pot body heating system 33.
The main control chip 11 is further configured to determine a height of the pot body 31 above the pot body heating system 33 according to the heating power of the pot body heating system 33, and identify the type of the pot body according to the determined height.
In the embodiment of the present invention, in order to detect the height of the pan body by the heating power of the pan body heating system 33, the corresponding relationship between the heating power of the pan body heating system 33 and the height of the pan body 31 from the pan body heating system 33 may be predefined. For example, if pan body 31 is raised 1mm from pan body heating system 33, the heating power of the system will be reduced(preset constant), the cooking device 3 is matched with a plurality of sets of pot bodies 31 according to the functional requirements, and is designed in such a way that the distance from each set of pot body 31 to the pot body heating system 33 is different when in use, and the heating powers of the pot bodies placed at different heights are correspondingly different under the same voltage condition; the input voltage of the pan body heating system 33 is different, the heating power is different, and the pan body 31 is placed under the condition of the same height and can be set as the voltage variation(the specific value is set by comprehensively considering the accuracy of the system identification voltage and the judgment requirement, for example, the specific value can be obtained10V, i.e., one gear per 10V) and power variation(predetermined constant) correspondence, i.e. each change in voltageThe power changesIt is noted that forAndthe specific numerical value of (2) is not limited, and can be defined according to different application scenes.
It should be noted that, the embodiment of the present invention may be applied to a cooking device that performs heating by using an electromagnetic heating method, but is not limited thereto, and any cooking device or other devices that can implement the embodiment of the present invention are within the protection scope of the embodiment of the present invention.
In the embodiment of the present invention, based on the above principle, the main control chip 11 may collect the heating current and the power input voltage of the pot body heating system 33 in real time during the pot body heating system 33 heats the pot body 31, and calculate the heating power according to the collected heating current and the collected power input voltage.

Before calculating the heating power, at the initial power-on time of the cooking device 3 system, it is necessary to first determine whether the pot body has been placed on the cooking device 3. Here, the judgment of whether the pot body has been placed on the cooking device 3 may be judged by a preset pot body detection unit or a pot body detection device, and a pot body signal for indicating whether the pot body 31 has been placed above the pot body heating system 33 is generated as a judgment result and sent to the main control chip 11; or the detection signal preset by main control chip 11, that is, whether pan body 31 is already placed above pan body heating system 33 is judged according to different forms (for example, high level or low level) of the detection signal. If the main control chip 11 determines that the pot body 31 is already placed above the pot body heating system 33, the pot body recognition device 1 enters a pot body recognition state; if the main control chip 11 determines that the pot body 31 is not placed above the pot body heating system 33, the pot body recognition device 1 enters a waiting state.
In the embodiment of the present invention, after the main control chip 11 determines that the pan body 31 has been placed above the pan body heating system 33, and the pan body recognition device 1 enters the pan body recognition state, it is necessary to determine whether the current power input voltage is stable before collecting the heating current and the power input voltage to calculate the heating power, so as to avoid the unstable power input voltage from damaging the cooking device 3.

The alarm information may take any one or more of the following forms: voice, music, whistling, flashing, vibration, etc., and the specific form of the alarm information is not limited herein.
In the embodiment of the present invention, when the power input voltage is within the preset normal voltage range, the main control chip 11 controls to output the driving signal to turn on the electromagnetic heating switch device, so as to control the electromagnetic heating system 33 to start full power heating.
