During the docking process between the plug-in piece 5' and the plug-in spring, the operator needs to operate both ends of the plug-in spring and the plug-in piece 5' with both hands.
[0003] However, this results in that the heating unit is often difficult to disassemble during the cleaning process of the electric heating cooking device, resulting in low cleaning efficiency and affecting the hygiene and service life of the electric heating cooking device. Summary of the Invention
[0004] In view of this, the present invention provides an electric heating cooking device to solve the problem in the related art that the heating unit of the electric heating cooking device is difficult to disassemble, which affects the hygiene and service life of the electric heating cooking device.
[0005] The present invention provides an electric heating cooking device, comprising:
[0006] The device body is provided with a plug slot, in which a conductive spring is fixedly provided, and the conductive spring is connected to the power supply circuit of the electric heating cooking device;
[0007] The heating module has a conductive pin at the end thereof, which is detachably plugged into the plug-in slot and can abut against the conductive spring when plugged into the plug-in slot, thereby conducting the heating module and the power supply circuit.
[0008] Beneficial effect: The heating module of the electric heating cooking device in the embodiment of the present invention is connected to the device body through a conductive needle instead of the cold end metal rod. The cold end metal rod can be abutted against the conductive spring sheet on the device body when plugged into the device body, thereby realizing power supply to the heating module.
[0009] Therefore, in the electric heating cooking device of the embodiment of the present application, the heating module is detachably arranged on the device body, which can facilitate the operator to remove the heating module from the device body and clean it separately, and the heating module is connected to the device body through a conductive needle, so that when the heating module is removed from the device body, the entire heating module can be directly cleaned with water, thereby improving the cleaning efficiency of the heating module, improving the hygiene of the electric heating cooking device, and helping to extend the service life of the electric heating cooking device.
[0010] In an optional embodiment, the heating module includes a module body, a connecting section, and a conductive pin, wherein the module body and the conductive pin are spaced apart along a first direction, the connecting section is connected between the module body and the conductive pin, and the plug-in slot includes:
[0011] a first plug-in section extending along a first direction and capable of allowing the connecting section and the conductive needle to pass through;
[0012] The second plug-in section is connected to the first plug-in section and is arranged at an angle. The conductive spring is arranged in the second plug-in section.
[0013] Beneficial effect: Through such a setting, during the assembly process, the operator can first place the connecting section and the conductive pin of the heating module into the first plug-in section along the extension direction of the first plug-in section, and then drive the heating module body to move along the extension direction of the second plug-in section to plug the heating module into the equipment body. The plug-in process is simple and convenient.
[0014] After the conductive needle is inserted into the second plug-in section, the angle structure between the first plug-in section and the second plug-in section can form a physical locking position, which can prevent the heating module from being dislodged due to vibration or accidental release, thereby improving the stability of the heating module.
[0015] Secondly, when the plug-in slot is configured to include a first plug-in section and a second plug-in section set at an angle, and the heating module is connected to the device body through a rigid conductive pin, the conductive pin can support the heating module by cooperating with the second plug-in section, thereby achieving the positioning of the heating module without the need for adding a fixed bracket.
[0016] In an optional embodiment, the module body is a heating plate, and the conductive needle includes a first conductive needle and a second conductive needle. The first conductive needle and the second conductive needle are arranged at intervals along the second direction, and the extension directions of the first conductive needle and the second conductive needle are parallel to each other, and the first direction is perpendicular to the second direction.
[0017] Beneficial effect: Through such an arrangement, the first conductive needle and the second conductive needle are arranged parallel to each other, which can ensure that the heating plate is in a horizontal state when the first conductive needle and the second conductive needle can be respectively connected to the corresponding second plug-in section, so as to avoid the module body from flipping or displacement.
[0018] In an optional embodiment, the first plug-in section extends in a vertical direction, and the second plug-in section extends in a horizontal direction.
[0019] Beneficial effect: Through such a setting, it can be ensured that when the heating module is plugged into the plug-in slot, the heating module itself is set horizontally, which can improve the supporting strength of the heating module and help the heating module to heat the food evenly, so that the heat released by the heating module can be directly transferred upward to the food, avoiding ineffective heat dissipation caused by tilted installation.
[0020] In an optional embodiment, the heating module further includes:
[0021] The sealing ring is sleeved on the outer periphery of the connecting section. When the conductive pin is inserted into the conductive spring sheet, the outer periphery of the sealing ring can be interference-fitted with the inner periphery of the second plug-in section.
[0022] Beneficial effect: Through such a setting, the sealing ring can not only seal the gap between the conductive pin and the second plug-in section, thereby preventing the cooking device from leaking electricity during operation, or moisture from entering the device body and contacting electronic components such as the power supply circuit in the device body.
[0023] In an optional embodiment, the device body further includes: a detection module capable of detecting the conductive needle;
[0024] The control module is in communication with the detection module and the power supply circuit of the electric heating cooking device, and can control the power supply circuit to supply power to the detection module when the detection module detects that the conductive pin is plugged in place.
[0025] Beneficial effect: Through such a configuration, the control module can ensure that the power supply circuit does not supply power to the heating module when the heating module is not installed in place, thereby improving the safety of the electric heating cooking device.
[0026] When the control module is installed in place, the detection module can timely monitor the conductive needles, so that the control module can timely control the power supply circuit to supply power to the heating module, thereby performing the cooking function normally.
[0027] In an optional embodiment, the detection module includes:
[0028] Micro switch, the push rod of the micro switch extends into the plug-in slot, and when the conductive needle and the conductive spring touch each other, the sealing ring can touch the push rod.
[0029] Beneficial effect: Through such an arrangement, the sealing ring can not only be used to improve the sealing performance of the electric heating cooking device, but also can be used to trigger the ejector rod so that the detection module can monitor the conductive needle in a timely manner.
[0030] In an optional embodiment, the module body includes:
[0031] Heating element housing;
[0032] The heating wire is arranged in the outer shell of the heating element and connected to the conductive needle;
[0033] The insulating sleeve is wrapped around the portion where the conductive needle passes through the outer shell of the heating element, and a high-temperature resistant rubber layer is filled between the insulating sleeve and the outer shell of the heating element.
[0034] Beneficial effect: Through such an arrangement, the overall waterproof performance of the heating module can be improved, ensuring that the entire heating module can be directly flushed with water.
[0035] In an optional embodiment, a guide section is formed at the notch of the second plug-in section, and the inner circumference of the guide section is configured to be reduced in diameter along the direction in which the conductive needle is plugged into the second plug-in section.
[0036] Advantageous effect: Through such an arrangement, the notch of the second plug-in section can guide the conductive needle, thereby facilitating the conductive needle to be inserted into the second plug-in section.
[0037] In an optional embodiment, the conductive spring includes:
[0038] The installation portion is arranged at the bottom of the plug-in slot;
[0039] The clamping pieces are arranged in pairs and are respectively connected to the two sides of the mounting portion. Each clamping piece is provided with a clamping protrusion protruding toward the other clamping piece, and the conductive needle can be clamped between the two clamping protrusions.
[0040] Beneficial effect: Through such a setting, the conductive spring can be fixedly set in the plug-in slot to ensure that the operator only needs to insert the conductive needle into the plug-in slot to complete the connection between the conductive needle and the device body, which is convenient for disassembly and cleaning of the heating module, and the conductive needle can be clamped between the two snap-fit protrusions, so that the conductive needle can be positioned between the heating module and the device body through two sets of sealing rings and two sets of snap-fit pieces, forming a total of four positioning points to ensure reliable limitation of the heating module and prevent the heating module from reversing or displacing without the need for additional fixed brackets.
[0041] On this basis, the snap-fit protrusion can form a guiding slope on the side of the conductive spring sheet facing the guide needle. Along the direction of insertion of the conductive needle and the conductive spring sheet, the guiding slopes of the two snap-fit protrusions are inclined in a direction approaching each other, thereby guiding the conductive needle and ensuring that the heating module can be inserted smoothly even when there is a deviation in the placement angle.
[0042] In an optional embodiment, the plug-in end of the conductive pin is formed with a rounded corner.
[0043] Advantageous effect: This arrangement facilitates the insertion of the conductive needle between the two engaging protrusions and prevents the end of the conductive needle from scratching the conductive spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0061] In related technologies, such as Figure 1 As shown, the device body 1' and the heating module 2', the end of the heating module 2' is provided with a cold end metal rod 3', the end of the cold end metal rod 3' is welded with an insert 5', and the device body is provided with a plug spring connected to a wire. During the docking process of the insert 5' and the plug spring, the user needs to manually lock and unlock the plug spring to achieve the docking and separation of the plug spring and the insert 5'. Therefore, the operator needs to use both hands to operate at both ends of the plug spring and the insert 5', which is inconvenient for the installation and disassembly of the heating module 2'.
[0062] Secondly, in the related art, the wire connected to the plug spring is a flexible structure, which cannot provide effective positioning for the plug spring and the heating module 2'. Therefore, a fixing bracket 4' needs to be added to implement positioning, which increases the number of parts in the electric heating cooking device.
[0063] The following combination Figures 2 to 10 , describing embodiments of the present invention.
[0064] According to an embodiment of the present invention, on the one hand, an electric heating cooking device is provided, including a device body 1 and a heating module 2.
[0065] The device body 1 is provided with a socket 101, in which a conductive spring 102 is fixedly mounted. The conductive spring 102 is connected to the power supply circuit of the electric heating cooking device. The heating module 2 is provided with a conductive pin 203 at the end. The conductive pin 203 is removably inserted into the socket 101 and, when inserted into the socket 101, abuts against the conductive spring 102, thereby connecting the heating module 2 to the power supply circuit.
[0066] The heating module 2 of the electric heating cooking device in an embodiment of the present invention is connected to the device body 1 through a conductive pin 203 instead of a cold end metal rod. The conductive pin 203 can be abutted against the conductive spring 102 on the device body 1 when plugged into the device body 1, thereby realizing power supply to the heating module 2.
[0067] Therefore, in the electric heating cooking device of the embodiment of the present application, the heating module 2 is detachably arranged on the device body 1, which can facilitate the operator to remove the heating module 2 from the device body 1 and clean it separately, and the heating module 2 is connected to the device body 1 through the conductive needle 203, so that when the heating module 2 is removed from the device body 1, the entire heating module 2 can be directly cleaned with water, thereby improving the cleaning efficiency of the heating module 2, improving the hygiene of the electric heating cooking device, and helping to extend the service life of the electric heating cooking device.
[0068] In one embodiment, the module body 201 of the conductive module includes a heating wire, which is preferably but not limited to being connected to the conductive needle 203 by welding or crimping to ensure a low resistance path.
[0069] For example, in an optional embodiment, the heating wire is a nickel-chromium wire, and is connected to the conductive needle 203 by argon arc welding, with a contact resistance of less than 1 mΩ.
[0070] In one embodiment, the module body 201 of the heating module 2 includes: a heating wire, a heating body shell and an insulating sleeve. The heating wire is arranged in the heating body shell, and the insulating sleeve is wrapped around the part of the conductive needle 203 passing through the heating body shell to provide electrical insulation and mechanical protection.
[0071] The gap between the insulating sleeve and the metal shell is filled with high-temperature resistant glue to prevent the intrusion of water vapor or pollutants.
[0072] The insulating sleeve is preferably, but not limited to, a ceramic insulating sleeve.
[0073] By such an arrangement, the overall waterproof performance of the heating module 2 can be improved, ensuring that the entire heating module 2 can be directly flushed with water.
[0074] In one embodiment, the heating module 2 includes a module body 201 , a connecting section 202 and a conductive needle 203 . The module body 201 and the conductive needle 203 are spaced apart along a first direction, and the connecting section 202 is connected between the module body 201 and the conductive needle 203 .
[0075] The plug-in slot 101 includes a first plug-in section 1012 and a second plug-in section 1013 .
[0076] The first plug section 1012 extends along the first direction, allowing the connection section 202 and the conductive pin 203 to pass through. The second plug section 1013 is connected to the first plug section 1012 and is arranged at an angle. The plug slot 101 is provided in the second plug section 1013.
[0077] Through such a setting, during the assembly process, the operator can first place the connecting section 202 and the conductive needle 203 of the heating module 2 into the first plug-in section 1012 along the extension direction of the first plug-in section 1012, and then drive the module body 201 to move along the extension direction of the second plug-in section 1013 to plug the heating module 2 into the device body 1. The plug-in process is simple and convenient.
[0078] After the conductive needle 203 is inserted into the second plug-in section 1013 , the angle structure between the first plug-in section 1012 and the second plug-in section 1013 can form a physical locking position, which can prevent the heating module 2 from vibrating or accidentally falling out, thereby improving the stability of the heating module 2 .
[0079] Secondly, when the plug-in slot 101 is configured to include a first plug-in section 1012 and a second plug-in section 1013 set at an angle, and the heating module 2 is connected to the device body 1 through a rigid conductive pin 203, the conductive pin 203 can support the heating module 2 by cooperating with the second plug-in section 1013, thereby realizing the positioning of the heating module 2 without the need for adding a fixed bracket.
[0080] As a changeable implementation, in an embodiment not shown in the drawings, the plug-in slot 101 is provided with only one plug-in section, and extends in a vertical direction.
[0081] In one embodiment, the module body 201 is a heating plate, and the conductive needle 203 includes a first conductive needle 2031 and a second conductive needle 2032. The first conductive needle 2031 and the second conductive needle 2032 are arranged at intervals along the second direction, and the extension directions of the first conductive needle 2031 and the second conductive needle 2032 are parallel to each other, and the first direction is perpendicular to the second direction.
[0082] By such an arrangement, the first conductive needle 2031 and the second conductive needle 2032 are arranged parallel to each other, which can ensure that the heating plate is in a horizontal state when the first conductive needle 2031 and the second conductive needle 2032 can be respectively connected to the corresponding second plug-in section 1013, so as to avoid the module body 201 from flipping or displacement.
[0083] As a convertible implementation, in an embodiment not shown in the drawings, the module body 201 can also be selected into other shapes, such as branch tube shape, fin shape, flat plate shape, spiral shape, mesh shape, grid shape or special curved surface shape.
[0084] In one embodiment, the first plug-in section 1012 extends in a vertical direction, and the second plug-in section 1013 extends in a horizontal direction.
[0085] By such a setting, it can be ensured that when the heating module 2 is plugged into the plug-in slot 101, the heating module 2 itself is set horizontally, which can improve the supporting strength of the heating module 2 and help the heating module 2 to heat the food evenly, so that the heat released by the heating module 2 can be directly transferred upward to the food, avoiding ineffective heat dissipation caused by tilted installation.
[0086] In one embodiment, the heating module 2 further includes a sealing ring 204 . The sealing ring 204 is sleeved on the outer periphery of the connecting section 202 . When the conductive pin 203 is inserted into and abuts against the conductive elastic sheet 102 , the outer periphery of the sealing ring 204 can be interference-fitted with the inner periphery of the insertion slot 101 .
[0087] Through such a setting, the sealing ring 204 can not only seal the gap between the conductive needle 203 and the second plug section 1013, thereby preventing the cooking device from leaking electricity during operation, or moisture from entering the device body 1 and contacting electronic components such as the power supply circuit in the device body 1.
[0088] In one embodiment, the sealing ring 204 is preferably but not limited to being made of elastic materials such as rubber or silicone.
[0089] In one embodiment, along the direction of the plugging of the conductive needle 203 and the second plug-in section 1013, the sealing ring 204 includes an abutment section and a plug-in section arranged in sequence. The plug-in section can be inserted into the second plug-in section 1013 of the slot and interference fit with the inner periphery of the second plug-in section 1013 to achieve sealing.
[0090] The outer diameter of the abutment section is larger than the outer diameter of the insertion section, and when the conductive pin 203 is inserted into place, the outer periphery of the second insertion section 1013 can abut against the device body 1, thereby preventing the conductive pin 203 from being inserted too deep, causing damage to the conductive pin 203 or the conductive spring 102, and helping to improve the sealing performance of the sealing ring 204.
[0091] In one embodiment, the device body 1 further includes a detection module and a control module.
[0092] The detection module can detect the conductive pin 203. The control module is in communication with the detection module and the power supply circuit of the electric heating cooking device, and can control the power supply circuit to supply power to the detection module when the detection module detects that the conductive pin 203 is plugged in.
[0093] By such a configuration, the control module can ensure that the electric cooking device does not supply power to the heating module 2 when the heating module 2 is not installed in place, thereby improving the safety of the electric cooking device.
[0094] When the control module is installed in place, the detection module can timely monitor the conductive needle 203, so that the control module can timely control the power supply circuit to supply power to the heating module, thereby performing the cooking function normally.
[0095] The control module may include a programmable logic control component (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well known to those skilled in the art and will not be described in detail here.
[0096] In one embodiment, the detection module includes a micro switch 3. The top rod 301 of the micro switch 3 extends into the plug slot 101. When the conductive needle 203 abuts against the conductive elastic sheet 102, the sealing ring 204 can trigger the top rod 301.
[0097] By such arrangement, the sealing ring 204 can not only be used to improve the sealing performance of the electric heating cooking device, but also can be used to trigger the ejector pin 301 so that the detection module can monitor the conductive needle 203 in a timely manner.
[0098] As a convertible implementation, in an embodiment not shown in the drawings, the detection module can also be selected as a photoelectric sensor or a proximity switch.
[0099] In one embodiment, the conductive spring 102 includes a mounting portion 1023 and a clamping piece 1021 .
[0100] The mounting portion 1023 is located at the bottom of the insertion slot 101. The engaging pieces 1021 are arranged in pairs and connected to either side of the mounting portion 1023. Each engaging piece 1021 has a engaging protrusion 1022 protruding toward the other engaging piece 1021. The conductive pin 203 can be sandwiched between the two engaging protrusions 1022.
[0101] Through such a setting, the conductive spring piece 102 can be fixedly set in the plug-in slot 101 to ensure that the operator only needs to insert the conductive needle 203 into the plug-in slot 101 to complete the plug-in between the conductive needle 203 and the device body 1, which is convenient for the disassembly and cleaning of the heating module 2, and the conductive needle 203 can be clamped between the two snap-fit protrusions 1022, so that the conductive needle 203 can be positioned between the heating module 2 and the device body 1 through two sets of sealing rings 204 and two sets of snap-fit pieces 1021, forming a total of four positioning points to ensure reliable limitation of the heating module 2 and prevent the heating module 2 from reversing or displacing without the need for additional fixed brackets.
[0102] On this basis, the snap-fit protrusion 1022 can form a guiding slope on the side of the conductive spring sheet 102 facing the guide needle. Along the direction of the insertion of the conductive needle 203 and the conductive spring sheet 102, the guiding slopes of the two snap-fit protrusions 1022 are inclined in a direction approaching each other, thereby guiding the conductive needle 203 and ensuring that the heating module 2 can be smoothly inserted even when there is a deviation in the placement angle.
[0103] In one embodiment, the plug-in end of the conductive pin 203 is formed with a rounded corner 2033 .
[0104] With such a configuration, the conductive needle 203 can be easily inserted between the two engaging protrusions 1022 , and the end of the conductive needle 203 can be prevented from scratching the conductive spring 102 .
[0105] In one embodiment, a guide section 1011 is formed at the notch of the second plug-in section 1013 , and the inner circumference of the guide section 1011 is configured to be reduced in diameter along the direction in which the conductive needle 203 is plugged into the second plug-in section 1013 .
[0106] By such a configuration, the notch of the second plug-in section 1013 can guide the conductive needle 203 , thereby facilitating the conductive needle 203 to be inserted into the second plug-in section 1013 .
[0107] Next, the disassembly process of the electric heating cooking device according to the embodiment of the present invention is described:
[0108] First, turn off the power to your electric cooking equipment and wait for it to cool down.
[0109] Then, pull the heating module 2 along the extension direction of the second plug section 1013 so that the conductive needle 203 is removed from between the two clamping pieces 1021 (see Figure 4 ), then pull the heating module 2 along the first direction to separate it from the device body 1;
[0110] Finally, the heating module 2 is taken out for cleaning or maintenance.
[0111] Next, the installation process of the electric heating cooking device according to the embodiment of the present invention is described:
[0112] First, place the cleaned heating module 2 into the first plug-in section 1012 along the first direction, and then move the heating module 2 along the extension direction of the second plug-in section 1013 so that the conductive needle 203 is clamped between the two card plates 1021 until the sealing ring 204 touches the top rod 301 of the microswitch 3, and then turn on the power, and the electric heating cooking device can operate normally.
[0113] In one embodiment, the electric heating cooking device is preferably but not limited to an oven or an air fryer.
[0114] To sum up, the heating module 2 of the electric heating cooking device in the embodiment of the present invention can be removed from the device body 1 and directly cleaned with water, thereby improving the cleaning efficiency of the heating module 2, improving the hygiene of the electric heating cooking device, and helping to extend the service life of the electric heating cooking device.
[0115] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope of protection claimed by the present invention.
