[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] In the present invention, unless otherwise stated, directional words such as "upper, lower, top, bottom" are usually used to describe the relative position of components in the direction shown in the drawings or in the vertical, perpendicular or gravity direction. Directional words such as "inside" and "outside" usually refer to the inside and outside of a chamber.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides an induction cooker heating device, in which a main control chip module 10 is arranged in a furnace body 2 of the induction cooker heating device, the main control chip module is connected to a heating control circuit, and a circuit coupling interface A3 of the heating control circuit is arranged on the top of the furnace body.

[0036] It should be noted that the main control chip module 10 of the induction cooker is generally connected to a power supply circuit with a plug (not shown). At the same time, different from only monitoring the temperature of the heating surface of the induction cooker, the induction cooker heating device of the present invention is provided with a special heating control circuit, which monitors the temperature, pressure and other parameters of the components heated by the induction cooker (such as the pot body 2) through the circuit coupling interface A3.

[0037] The electromagnetic cooker heating device of the present invention also includes a pot body 2, a sensor module 40 is arranged in the pot body 2, and a circuit coupling interface B4 electrically connected to the sensor module 40 is arranged at the bottom of the pot body 2; when the bottom of the pot body 2 is supported on the top of the furnace body 1, the circuit coupling interface B4 is engaged with the circuit coupling interface A3, so that the main control chip module 10 can be electrically connected to the sensor module 40 to control heating. In this way, the electromagnetic cooker heating device of the present invention is provided with a heating control circuit and its circuit coupling interface A compared to the ordinary electromagnetic cooker, which can be engaged with the circuit coupling interface B of the pot body 2 of the electric pressure cooker, etc., so as to combine the electromagnetic cooker with the pot body 2, thereby realizing the use of the electromagnetic cooker alone or in combination, which is highly practical and has complete functions, and saves a separate placement space for the electromagnetic cooker in the limited kitchen space. It should be noted that the pot body 2 matched with the furnace body 1 in the electromagnetic cooker heating device of the present invention is not an ordinary pot body, such as a separate metal pot used for hot pot, but a pot body with a sensor and a circuit coupling interface B, such as the pot body of an electric pressure cooker or an electric rice cooker.

[0038] by Figure 1 , Figure 2Taking the IH electric pressure cooker as an example, it is assembled from the furnace body 1 of the induction cooker and the pot body 2 of the electric pressure cooker. The pot body 2 includes an inner pot, a pot body 21 and a pot cover 22. When used in combination, the bottom of the pot body 2 of the electric pressure cooker is placed on the induction cooker for heating, i.e., IH heating. When the pot body 2 is placed on the furnace body 1, the circuit coupling interface B4 is connected with the circuit coupling interface A3, and the heating control circuit between the main control chip module 10 and the sensor module 40 in the pot body 2 is turned on, as shown in FIG. Figure 3 The main control chip module 10 collects and monitors the temperature, pressure and other parameters in the electric pressure cooker in real time through the heating control circuit to control the heating, thus forming an IH electric pressure cooker with complete functions.

[0039] In this way, through the physical connection relationship between the coupling interfaces, the present invention realizes the combined use of the induction cooker and the pot body in the induction cooker heating device. Of course, the induction cooker can also be used alone, that is, the pot body 2 of the electric pressure cooker is separated from the furnace body 1. As described below, at this time, the circuit coupling interface A3 is disconnected to achieve short-circuit protection to prevent damage to the main control chip. At this time, the induction cooker can be used alone, for example, for heating hot pot. The induction cooker can be used alone and can be assembled to form an IH electric pressure cooker in multiple ways, which greatly increases the frequency of use of the induction cooker. When it is assembled in the electric pressure cooker, there is no need to reserve a separate space for the induction cooker, which makes the remaining space in the kitchen larger.

[0040] The sensor module 40 disposed in the pot body 2 at least includes a temperature sensor 41 and a pressure sensor 42, and the temperature sensor 41 and the pressure sensor 42 are connected in parallel to the circuit coupling interface B4. Figure 3 That is, when the IH electric pressure cooker is heating, at least the temperature and pressure of the pot body 2 should be monitored in real time to adjust the heating amount of the induction cooker.

[0041] exist Figure 1 , Figure 2 In the figure, the circuit coupling interface A3 is specifically a concave joint that is recessed from the top surface of the furnace body 1, and the circuit coupling interface B4 is a convex joint that extends downward from the bottom surface of the pot body 2. This concave and convex joint can not only realize electrical connection with each other through physical pairing of the joints when the pot body 2 is seated on the furnace body 1, but also the concave and convex joint can be used as an assembly positioning so that the pot body 2 can be accurately placed in the central heating area of ​​the furnace body 1, thereby improving the heating efficiency and being more conducive to the accurate judgment of the main control chip module 10. Of course, the circuit coupling interface A3 can also be a convex joint, and the circuit coupling interface B4 is a concave joint. The design of the convex and concave joints in the illustrated embodiment is made only according to the usage habits and the favorable factors of preventing the convex joint from obstructing other pot bodies from being placed on the induction cooker. Moreover, the circuit coupling interface is not limited to the concave and convex joint method shown in the figure, but can also be other methods such as lead plug and socket methods.

[0042] exist Figure 2In the assembled IH electric pressure cooker shown, it is necessary to prevent water overflowing from the pot body 2 from entering the notched circuit coupling interface A3, causing a short circuit or even burning the main control chip module 10. To this end, Figure 2 The convex joint-shaped circuit coupling interface B4 shown is provided with an elastic sealing sleeve, such as a high temperature resistant rubber sealing sleeve, etc., which is elastically pressed against the top surface of the furnace body 1 by the gravity of the pot body 2, and can effectively prevent water from the top surface from invading the concave hole interface. In addition, for further waterproofing, a waterproof rubber sleeve can be embedded in the concave circuit coupling interface A3, and the top peripheral edge of the waterproof rubber sleeve protrudes from the top surface of the furnace body 1 to form a waterproof wall. Alternatively, a circumferential waterproof wall surrounding the circuit coupling interface A3 can be directly provided on the top surface of the furnace body 1.

[0043] To further facilitate the placement of the pot body 2 and make it firmly connected, Figure 1 , Figure 2 In the embodiment shown, the top surface of the furnace body 1 is preferably formed as a step surface, which includes a relatively high high-water level surface, a relatively low low-water level surface, and a vertical step surface connecting the high-water level surface and the low-water level surface. The vertical step surface in the figure is in the shape of an inclined surface to correspond to the peripheral inclined surface supporting the bottom end of the pot body 2. As can be seen in the figure, the circuit coupling interface A3 is arranged on the low-water level surface, and the pot body 2 is supported on the low-water level surface and positioned against the vertical step surface. On the basis of the auxiliary positioning of the above-mentioned concave and convex joints, the pot body 2 can be placed on the furnace body 1 in precise alignment through step positioning, and the furnace body 1 and the pot body 2 are firmly combined, and the pot body 2 is not easy to move. Therefore, when the induction cooker and the pot body 2 are assembled, the coupling interface and the step portion on the surface of the induction cooker can be positioned and matched, so that the user can accurately place the pot body 2 on the induction cooker and form a circuit connection to form a complete IH electric pressure cooker.

[0044] The induction cooker of the present invention also includes an operation display panel 7 and a wire reel 9. The high-water level surface in the above-mentioned step surface serves as an operation display interface 8. An operation display panel 7 is embedded below the operation display interface 8. The main control chip module 10 can feed back sensor detection signals such as temperature and pressure to the operation display panel 7, and display them to the user in real time through the operation display interface 8 for user operation.

[0045] The low-water surface in the above-mentioned step surface includes a central heating area and an edge installation area. A wire drum 9 is provided directly below the central heating area, and the circuit coupling interface A3 is arranged in the edge installation area away from the wire drum 9, so as to reserve a larger space for the central heating area and avoid heating of the circuit rubber wire, rubber sleeve, etc.

[0046] When the induction cooker is used alone, since there is an exposed circuit coupling interface A3, in order to prevent safety hazards such as interface short circuit and electric shock, the induction cooker heating device of the present invention also particularly includes a switch circuit module 20, such as Figure 3As shown, the switch circuit module 20 is arranged on the heating control circuit between the main control chip module 10 and the circuit coupling interface A3, and is connected in series with the interface circuit module 30. The switch circuit module 20 may include a plurality of switches and switch control ports, and the main control chip module 10 communicates with the switch control port to control each switch to cut off or conduct the circuit.

[0047] In addition, the induction cooker heating device of the present invention may further include a pot body assembly detection module 50 for detecting whether the pot body 2 supported on the furnace body 1 is placed in place, and the main control chip module 10 is configured to receive the detection signal of the pot body assembly detection module 50 and switch the switch circuit module 20 according to the detection signal. In the actual operation process, the detection signal of whether the pot body 2 is placed in place detected by the pot body assembly detection module 50 can be fed back to the operation display interface 8 to remind the user to pay attention to whether the pot body 2 is in a separated state or an assembled state, and even as mentioned below, combined with the switch circuit module 20 for further anti-short circuit safety locking.

[0048] exist Figure 2 , Figure 3 In the embodiment, the pot body assembly detection module 50 includes a reed switch 5 and a permanent magnet 6. The reed switch 5 is installed on the top surface of the furnace body 1 and is electrically connected to the main control chip module 10. The permanent magnet 6 is installed on the bottom of the pot body 2 opposite to the reed switch 5. When the pot body 2 is placed in place on the furnace body 1, the permanent magnet 6 acts on the reed switch 5, turns on the reed switch circuit, and feeds back the detection signal to the main control chip module 10. After obtaining the above detection signal, the main control chip module 10 confirms that the pot body is assembled in place, and can control the switch circuit module 20 to turn on, completely turn on the heating control circuit, and control the heating of the pot body 2.

[0049] When the induction cooker is used independently, the reed switch circuit is in a disconnected state, and the main control chip module 10 can confirm that the pot body is separated, thereby not only feeding back the pot body separation information to the operation display interface 8, but also disconnecting the electrical connection between the main control chip module 10 and the circuit coupling interface A3 to achieve short circuit protection, prevent short circuits caused by interface short circuits or accidental touches, and possible failures such as damage to the main control chip. In other words, when the induction cooker is used alone, it can ensure that the circuit coupling interface A3 is completely inoperative, completely eliminating any potential safety hazards it may bring.

[0050] In summary, the electromagnetic cooker heating device of the present invention can be used as an electromagnetic heating pot, and can also be used alone as an electromagnetic cooker, with complete functions, strong practicality, exquisite assembly structure, and high equipment safety and reliability. The pot body 2 can be various products such as an electric pressure cooker or an electric rice cooker (which constitutes an IH electric rice cooker after assembly), and has a wide range of applications.

[0051] The above describes the electromagnetic cooker heating device of the present invention from the perspective of structure and function. Figure 3The control device of the electromagnetic oven heating device of the present invention is specifically described. The pot body 2 of the electromagnetic oven heating device can be detachably supported on the furnace body 1. The control device includes:

[0052] The sensor module 40 is disposed in the pot body 2 and is used for collecting signals such as temperature and pressure in the pot body 2;

[0053] The main control chip module 10 is responsible for signal reception, transmission control and heating control of the induction cooker. The main control chip module 10 is connected to the sensor module 40 through a heating control circuit to control heating; and

[0054] The interface circuit module 30 is arranged in the heating control circuit. The interface circuit module 30 is configured to turn on the heating control circuit when the pot body 2 is supported on the furnace body 1, and to turn off the heating control circuit when the pot body 2 is separated from the furnace body 1.

[0055] Through the interface circuit module 30 of the control device, different operation controls of turning on or off the heating control circuit can be realized when the pot body 2 is separated or assembled from the furnace body 1. When the interface circuit module 30 turns on the heating control circuit, the main control chip module 10 communicates with the sensor module 40 to control the heating of the pot body 2 by the induction cooker, for example, to control the heating power, surface heating temperature, heating duration and other parameters of the induction cooker.

[0056] The interface circuit module 30 may be a wireless communication module, using a wireless interface, etc. However, from the perspective of user convenience and safety and reliability, the interface circuit module 30 of the present invention is preferably a wired interface module, including a circuit coupling interface A3 and a circuit coupling interface B4. The circuit coupling interface A3 is arranged at the top of the furnace body 1 and is electrically connected to the main control chip module 10, and the circuit coupling interface B4 is arranged at the bottom of the pot body 2; wherein, when the bottom of the pot body 2 is supported on the top of the furnace body 1, the circuit coupling interface B4 engages the circuit coupling interface A3 to conduct the heating control circuit.

[0057] The control device may also include a pot body assembly detection module 50 for detecting whether the pot body 2 supported on the furnace body 1 is placed in place. The main control chip module 10 communicates with the pot body assembly detection module 50 to receive a detection signal from the pot body assembly detection module 50. The detection signal can be fed back to the operation display panel 7 below the operation display interface 8 and intuitively reflected to the user through the operation display interface 8 on the top surface of the furnace body 1.

[0058] exist Figure 2 , Figure 3As a preferred specific implementation, the pot assembly detection module 50 includes a reed switch 5 and a permanent magnet 6. The reed switch 5 is installed on the top surface of the furnace body 1 and is electrically connected to the main control chip module 10. The permanent magnet 6 is installed at the bottom of the pot body 2 opposite to the reed switch 5. Of course, the pot assembly detection module 50 can also be other structural forms, for example, it includes a photoelectric emitting component and a photoelectric receiving component, and the photoelectric emitting component and the photoelectric receiving component are respectively arranged on the top surface of the furnace body 1 and the bottom of the pot body 2 at the corresponding position.

[0059] exist Figure 3 In the embodiment, the control device further preferably includes a switch circuit module 20, which is arranged on the heating control circuit between the main control chip module 10 and the circuit coupling interface A3. The switch circuit module 20 can be controlled manually or electrically. In this embodiment, the switch circuit module 20 is automatically controlled by electric control to achieve short circuit protection of the circuit coupling interface A.

[0060] At this time, the main control chip module 10 is configured to switch and control the switch circuit module 20 according to the detection signal of the pot body assembly detection module 50; when the pot body assembly detection module 50 detects that the pot body 2 is seated on the furnace body 1, it sends a pot body assembly signal, and the main control chip module 10 sends a switch closing signal to the switch circuit module 20 according to the pot body assembly signal to conduct the heating control circuit between the main control chip module 10 and the circuit coupling interface A3;

[0061] Alternatively, the pot body assembly detection module 50 sends a pot body separation signal when it detects that the pot body 2 is separated from the furnace body 1, and the main control chip module 10 sends a switch disconnect signal to the switch circuit module 20 according to the pot body separation signal to disconnect the heating control circuit between the main control chip module 10 and the circuit coupling interface A3.

[0062] Specifically, after the induction cooker is powered on, the main control chip module 10 first detects whether the reed switch 5 is turned on. If the reed switch 5 is turned on, the interface circuit module 30 is also turned on, and it is determined that the matching pot body 2 is heated and used as an IH electric pressure cooker. Then the control switch circuit module 20 is closed, and the heating control circuit between the main control chip module 10 and the circuit coupling interface A3 is normally turned on;

[0063] If some reed switches 5 are disconnected, it is determined that the pot body 2 is not matched for heating, the induction cooker is used alone or the pot body 2 is not placed properly, and the main control chip module 10 controls the switch circuit module 20 to disconnect, that is, the heating control circuit between the main control chip module 10 and the circuit coupling interface A3 is disconnected. At this time, even if the circuit coupling interface A3 is short-circuited due to other conductors or any other reasons, the main control chip module 10 will not be damaged.

[0064] In summary, Figure 3The control principle of the control device of the induction cooker heating device of the present invention is simple and the control elements are few. Combined with the assembly process of the pot body 2 and the furnace body 1 in the induction cooker heating device of the present invention, the interface conduction of the heating control circuit is realized, which not only conforms to the user's operating habits, but also maintains high safety and reliability through the hardware interface connection method. In particular, the specially added control switch circuit module 20 and the pot body assembly detection module 50 can further prevent the short circuit of the interface and protect the entire control device from damage.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention, such as the pot assembly detection module 50 can also be other circuit forms including proximity switches, and such changes should be included in the protection scope of the present invention.

[0066] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0067] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
