Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to an electric heating cooking device. Background Art

[0002] Taking an air fryer or an oven as an example, an electric heating cooking device includes a device main body 1' and a heating module 2' (see Figure 1 ). A cold-end metal rod 3' is provided at the end of the heating module. A terminal of the cold-end metal rod 3' is welded with a tab. A socket with a wire connected thereto is provided on the device main body. During the docking process of the tab 5' and the socket, the operator needs to operate with both hands at both ends of the socket and the tab 5'.

[0003] However, this results in that during the cleaning process of the electric heating cooking device, the heating unit is often difficult to disassemble, causing 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, affecting the hygiene and service life of the electric heating cooking device.

[0005] The present invention provides an electric heating cooking device, including: A device main body, on which a plug-in slot is provided, and a conductive elastic sheet is fixedly arranged in the plug-in slot. The conductive elastic sheet is connected to the power supply circuit of the electric heating cooking device; A heating module, at the end of which a conductive pin is provided. The conductive pin is detachably plugged into the plug-in slot and can be in contact with the conductive elastic sheet when plugged into the plug-in slot, so as to conduct the heating module and the power supply circuit.

[0006] Advantageous Effects: In the electric heating cooking device according to the embodiment of the present invention, the heating module is connected to the device main body by a conductive pin instead of a cold-end metal rod. The cold-end metal rod can be in contact with the conductive elastic sheet on the device main body when plugged into the device main body, thereby realizing the power supply of the heating module.

[0007] Therefore, in the electric heating cooking device according to the embodiment of the present application, the heating module is detachably arranged on the device main body, which is convenient for the operator to remove the heating module from the device main body and clean it separately. Moreover, the heating module is connected to the device main body by a conductive pin, so that when the heating module is removed from the device main body, the entire heating module can be directly washed 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.

[0008] In an alternative embodiment, the heating module includes a module body, a connecting section, and conductive pins. The module body and the conductive pins are spaced apart along a first direction. The connecting section is connected between the module body and the conductive pins. The insertion slot includes: A first insertion section extending along the first direction and capable of allowing the connecting section and the conductive pins to pass through; A second insertion section connected to the first insertion section and arranged at an angle. A conductive elastic piece is disposed in the second insertion section.

[0009] Beneficial effects: With such an arrangement, during the assembly process, the operator can first place the connecting section and the conductive pins of the heating module into the first insertion section along the extension direction of the first insertion section, and then drive the heating module body to move along the extension direction of the second insertion section to insert the heating module onto the device body. The insertion process is simple and convenient.

[0010] Moreover, after the conductive pins are inserted into the second insertion section, the angular structure between the first insertion section and the second insertion section can form a physical position-locking, which can prevent the heating module from being disengaged due to vibration or accident, thereby improving the stability of the heating module.

[0011] Secondly, when the insertion slot is arranged to include a first insertion section and a second insertion section arranged at an angle, and the heating module is connected to the device body through rigid conductive pins, the conductive pins can support the heating module through cooperation with the second insertion section, thereby achieving the positioning of the heating module without adding a fixing bracket.

[0012] In an alternative embodiment, the module body is a heating plate. The conductive pins include a first conductive pin and a second conductive pin. The first conductive pin and the second conductive pin are spaced apart along a second direction, and the extension directions of the first conductive pin and the second conductive pin are parallel to each other. The first direction is perpendicular to the second direction.

[0013] Beneficial effects: With such an arrangement, the first conductive pin and the second conductive pin are arranged in parallel, which can ensure that the heating plate is in a horizontal state when the first conductive pin and the second conductive pin are respectively connected to the corresponding second insertion sections, so as to prevent the module body from flipping or displacing.

[0014] In an alternative embodiment, the first insertion section extends in the vertical direction, and the second insertion section extends in the horizontal direction.

[0015] Beneficial effects: With such an arrangement, when the heating module is inserted into the insertion slot, the heating module itself is in a horizontal state, which can improve the support strength of the heating module and help the heating module heat food evenly, so that the heat released by the heating module can be directly transmitted upward to the food, avoiding ineffective heat dissipation caused by inclined installation.

[0016] In an alternative embodiment, the heating module further includes: A sealing ring sleeved on the outer periphery of the connecting section. When the conductive pin abuts against the conductive elastic sheet, the outer periphery of the sealing ring can be in interference fit with the inner periphery of the second plugging section.

[0017] Beneficial effects: By setting it like this, the sealing ring can not only seal the gap between the conductive pin and the second plugging section, thereby preventing the cooking device from leaking electricity during operation or moisture from entering the device main body and contacting electronic components such as the power supply circuit inside the device main body.

[0018] In an alternative embodiment, the device main body further includes: a detection module capable of detecting the conductive pin; A control module communicatively connected to the detection module and the power supply circuit of the electro-heating cooking device, and capable of controlling the power supply circuit to supply power to the detection module when the detection module detects that the conductive pin is plugged in place.

[0019] Beneficial effects: By setting it like this, 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, so as to improve the safety of the electro-heating cooking device.

[0020] When the control module is installed in place, the detection module can timely monitor the conductive pin, so that the control module can timely control the power supply circuit to supply power to the heating module, thereby normally executing the cooking function.

[0021] In an alternative embodiment, the detection module includes: A microswitch, the ejector rod of the microswitch extends into the plugging groove, and when the conductive pin abuts against the conductive elastic sheet, the sealing ring can touch the ejector rod.

[0022] Beneficial effects: By setting it like this, the sealing ring can not only be used to improve the sealing performance of the electro-heating cooking device, but also be used to touch the ejector rod, so that the detection module can timely monitor the conductive pin.

[0023] In an alternative embodiment, the module main body includes: A heating element housing; A heating wire disposed inside the heating element housing and connected to the conductive pin; An insulating sleeve wrapping the part of the conductive pin passing through the heating element housing, and a high-temperature resistant adhesive layer is filled between the insulating sleeve and the heating element housing.

[0024] Beneficial effects: By setting it like this, the waterproof performance of the whole heating module can be improved, ensuring that the whole heating module can be directly rinsed with water.

[0025] In an alternative embodiment, a guiding section is formed at the notch of the second plugging section, and the inner circumference of the guiding section is arranged with a reduced diameter along the direction in which the conductive pin is plugged into the second plugging section.

[0026] Beneficial effects: By setting like this, the notch of the second plugging section can guide the conductive pin, thus facilitating the insertion of the conductive pin into the second plugging section.

[0027] In an alternative embodiment, the conductive elastic piece includes: A mounting portion, arranged at the bottom of the plugging slot; Clamping pieces, arranged in pairs and respectively connected to both sides of the mounting portion. Each clamping piece is provided with a clamping convex portion protruding towards the other clamping piece, and the conductive pin can be clamped between the two clamping convex portions.

[0028] Beneficial effects: By setting like this, the conductive elastic piece can be fixedly arranged in the plugging slot to ensure that the operator only needs to insert the conductive pin into the plugging slot to complete the plugging between the conductive pin and the device main body, which is convenient for the disassembly and cleaning of the heating module. Moreover, the conductive pin can be clamped between the two clamping convex portions, so that the heating module and the device main body can position the conductive pin through two sets of sealing rings and two sets of clamping pieces, forming a total of four positioning points to ensure reliable limiting of the heating module and prevent the heating module from reversing or displacing without adding a fixing bracket.

[0029] On this basis, the clamping convex portion can form a guiding inclined surface on the side of the conductive elastic piece facing the guiding pin. Along the direction in which the conductive pin is plugged into the conductive elastic piece, the guiding inclined surfaces of the two clamping convex portions are inclined in the direction of approaching each other, thereby being able to play a guiding role for the conductive pin and ensuring that it can be smoothly inserted even when the placement angle of the heating module is deviated.

[0030] In an alternative embodiment, a chamfered corner is formed at the plugging end of the conductive pin.

[0031] Beneficial effects: By setting like this, it is convenient for the conductive pin to be inserted between the two clamping convex portions and avoid scratching the conductive elastic piece with the end of the conductive pin. Description of the Drawings

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] In the related art, as Figure 1As 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 a plug 5', and the device body is provided with a plug spring connected with a wire. During the docking process of the plug 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 plug 5'. Therefore, the operator needs to use both hands to operate at both ends of the plug spring and the plug 5', which is not convenient for the installation and disassembly of the heating module 2'.

[0037] 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', so it is necessary to add a fixed bracket 4' to implement positioning, which increases the number of parts in the electric heating cooking device.

[0038] Combine the following Figures 2 to 10 , describing an embodiment of the present invention.

[0039] According to an embodiment of the present invention, on the one hand, an electric heating cooking device is provided, comprising a device body 1 and a heating module 2.

[0040] The device body 1 is provided with a plug-in slot 101, in which a conductive spring 102 is fixedly arranged, and the conductive spring 102 is connected to the power supply circuit of the electric heating cooking device. The end of the heating module 2 is provided with a conductive pin 203, which is detachably plugged into the plug-in slot 101 and can abut against the conductive spring 102 when plugged into the plug-in slot 101, thereby conducting the heating module 2 and the power supply circuit.

[0041] The heating module 2 of the electric heating cooking device of the embodiment of the present invention is connected to the device body 1 via a conductive pin 203 instead of a cold end metal rod. The conductive pin 203 can abut against the conductive spring sheet 102 on the device body 1 when plugged into the device body 1, thereby realizing power supply of the heating module 2.

[0042] 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, can improve the hygiene of the electric heating cooking device, and help to extend the service life of the electric heating cooking device.

[0043] 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.

[0044] Exemplarily, in an alternative embodiment, the heating wire is a nickel-chromium wire and is welded to the conductive pin 203 by argon arc welding, with a contact resistance < 1 mΩ.

[0045] In one embodiment, the module body 201 of the heating module 2 includes: a heating wire, a heating element housing, and an insulating sleeve. The heating wire is disposed inside the heating element housing, and the insulating sleeve wraps around the portion of the conductive pin 203 that passes through the heating element housing to provide electrical insulation and mechanical protection.

[0046] The gap between the insulating sleeve and the metal housing is filled with a high-temperature resistant adhesive to prevent moisture or contaminants from entering.

[0047] Among them, the insulating sleeve is preferably but not limited to a ceramic insulating sleeve.

[0048] By setting it in this way, the overall waterproof performance of the heating module 2 can be improved, ensuring that the entire heating module 2 can be directly rinsed with water.

[0049] In one embodiment, the heating module 2 includes a module body 201, a connecting section 202, and a conductive pin 203. The module body 201 and the conductive pin 203 are spaced apart along a first direction, and the connecting section 202 is connected between the module body 201 and the conductive pin 203.

[0050] The insertion slot 101 includes a first insertion section 1012 and a second insertion section 1013.

[0051] Among them, the first insertion section 1012 extends along the first direction and can allow the connecting section 202 and the conductive pin 203 to pass through. The second insertion section 1013 is connected to the first insertion section 1012 and is disposed at an angle. The insertion slot 101 is disposed within the second insertion section 1013.

[0052] By setting it in this way, during the assembly process, the operator can first place the connecting section 202 and the conductive pin 203 of the heating module 2 into the first insertion section 1012 along the extension direction of the first insertion section 1012, and then drive the module body 201 to move along the extension direction of the second insertion section 1013 to insert the heating module 2 onto the device body 1. The insertion process is simple and convenient.

[0053] Moreover, after the conductive pin 203 is inserted into the second insertion section 1013, the angular structure between the first insertion section 1012 and the second insertion section 1013 can form a physical locking position, which can prevent the heating module 2 from being disengaged due to vibration or accident, thereby improving the stability of the heating module 2.

[0054] Secondly, when the insertion slot 101 is set to include a first insertion section 1012 and a second insertion section 1013 arranged at an angle, and the heating module 2 is connected to the device main body 1 through rigid conductive pins 203, the conductive pins 203 can support the heating module 2 by cooperating with the second insertion section 1013, thereby realizing the positioning of the heating module 2 without adding a fixing bracket.

[0055] As a transformable embodiment, in an embodiment not shown in a drawing, the insertion slot 101 is only provided with one insertion section and extends in the vertical direction.

[0056] In one embodiment, the module main body 201 is a heating plate, and the conductive pins 203 include a first conductive pin 2031 and a second conductive pin 2032. The first conductive pin 2031 and the second conductive pin 2032 are arranged at intervals in the second direction, and the extending directions of the first conductive pin 2031 and the second conductive pin 2032 are parallel to each other. The first direction is perpendicular to the second direction.

[0057] By setting like this, the first conductive pin 2031 and the second conductive pin 2032 are arranged parallel to each other, and when the first conductive pin 2031 and the second conductive pin 2032 can be respectively connected to the corresponding second insertion section 1013, it can ensure that the heating plate is in a horizontal state to prevent the module main body 201 from flipping or displacing.

[0058] As a transformable embodiment, in an embodiment not shown in a drawing, the module main body 201 can also be selected as other shapes, such as a branch pipe shape, a fin shape, a flat plate shape, a spiral shape, a mesh shape, a grid shape or a special-shaped curved surface shape, etc.

[0059] In one embodiment, the first insertion section 1012 extends in the vertical direction, and the second insertion section 1013 extends in the horizontal direction.

[0060] By setting like this, when the heating module 2 is inserted into the insertion slot 101, the heating module 2 itself is horizontally arranged, which can improve the support strength of the heating module 2 and help the heating module 2 to heat food evenly, so that the heat released by the heating module 2 can be directly transmitted upward to the food, avoiding ineffective heat dissipation caused by inclined installation.

[0061] 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 abuts against the conductive elastic sheet 102, the outer periphery of the sealing ring 204 can be in interference fit with the inner periphery of the insertion slot 101.

[0062] By setting it like this, the sealing ring 204 can not only seal the gap between the conductive pin 203 and the second insertion section 1013, thereby preventing electric leakage when the cooking device is working or moisture from entering the device main body 1 and contacting electronic components such as the power supply circuit in the device main body 1.

[0063] In one embodiment, the sealing ring 204 is preferably but not limited to being made of an elastic material such as rubber or silica gel.

[0064] In one embodiment, along the insertion direction of the conductive pin 203 and the second insertion section 1013, the sealing ring 204 includes an abutting section and an insertion section arranged in sequence. The insertion section can be inserted into the second insertion section 1013 of the slot and is in interference fit with the inner circumference of the second insertion section 1013 to achieve sealing.

[0065] The outer diameter of the abutting section is greater than the outer diameter of the insertion section, and it can abut against the device main body 1 on the outer circumference of the second insertion section 1013 when the conductive pin 203 is inserted in place, thereby preventing the insertion depth of the conductive pin 203 from being too deep and causing damage to the conductive pin 203 or the conductive elastic piece 102, and helping to improve the sealing performance of the sealing ring 204.

[0066] In one embodiment, the device main body 1 further includes a detection module and a control module.

[0067] Among them, the detection module can detect the conductive pin 203. The control module is communicatively connected to the detection module and the power supply circuit of the electrothermal 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 inserted in place.

[0068] By setting it like this, the control module can ensure that the electrothermal cooking device does not supply power to the heating module 2 when the heating module 2 is not installed in place, so as to improve the safety of the electrothermal cooking device.

[0069] When the control module is installed in place, the detection module can timely monitor the conductive pin 203, so that the control module can timely control the power supply circuit to supply power to the heating module, so as to normally execute the cooking function.

[0070] The control module may include programmable logic control components (such as PLC or CPU), a memory, and electronic components connected to the programmable logic control components, etc., which are well known to those skilled in the art and will not be elaborated here.

[0071] In one embodiment, the detection module includes a microswitch 3. The ejector rod 301 of the microswitch 3 extends into the insertion slot 101, and when the conductive pin 203 abuts against the conductive elastic piece 102, the sealing ring 204 can touch the ejector rod 301.

[0072] By setting it this way, the sealing ring 204 can not only be used to improve the sealing performance of the electro-heating cooking device, but also be used to trigger the ejector rod 301 so that the detection module can monitor the conductive pin 203 in a timely manner.

[0073] As a transformable embodiment, in an embodiment not shown in one of the drawings, the detection module can also be alternatively an optoelectronic sensor or a proximity switch, etc.

[0074] In one embodiment, the conductive elastic piece 102 includes a mounting portion 1023 and a clamping piece 1021.

[0075] Among them, the mounting portion 1023 is arranged at the bottom of the insertion slot 101. The clamping pieces 1021 are arranged in pairs and are respectively connected to both sides of the mounting portion 1023. Each clamping piece 1021 is provided with a clamping convex portion 1022 protruding towards the other clamping piece 1021, and the conductive pin 203 can be clamped between the two clamping convex portions 1022.

[0076] By setting it this way, the conductive elastic piece 102 can be fixedly arranged in the insertion slot 101 to ensure that the operator only needs to insert the conductive pin 203 into the insertion slot 101 to complete the insertion of the conductive pin 203 and the device main body 1, which is convenient for the disassembly and cleaning of the heating module 2. Moreover, the conductive pin 203 can be clamped between the two clamping convex portions 1022, so that the heating module 2 and the device main body 1 can position the conductive pin 203 through two sets of sealing rings 204 and two sets of clamping pieces 1021, forming a total of four positioning points to ensure reliable limiting of the heating module 2 and prevent the heating module 2 from reversing or displacing without adding a fixing bracket.

[0077] On this basis, the clamping convex portion 1022 can form a guiding inclined surface on the side of the conductive elastic piece 102 facing the guiding pin. Along the direction of insertion of the conductive pin 203 and the conductive elastic piece 102, the guiding inclined surfaces of the two clamping convex portions 1022 are inclined in the direction of approaching each other, thereby being able to play a guiding role for the conductive pin 203 and ensuring that it can be smoothly inserted even when the placement angle of the heating module 2 is deviated.

[0078] In one embodiment, a chamfered corner 2033 is formed at the insertion end of the conductive pin 203.

[0079] By setting it this way, it is convenient for the conductive pin 203 to be inserted between the two clamping convex portions 1022 and prevent the end of the conductive pin 203 from scratching the conductive elastic piece 102.

[0080] In one embodiment, a guiding section 1011 is formed at the notch of the second insertion section 1013. Along the direction of insertion of the conductive pin 203 and the second insertion section 1013, the inner circumference of the guiding section 1011 is set with a reduced diameter.

[0081] By setting it in this way, the notch of the second insertion section 1013 can guide the conductive pin 203, thus facilitating the insertion of the conductive pin 203 into the second insertion section 1013.

[0082] Next, the disassembly process of the electric heating cooking device according to the embodiment of the present invention will be described: First, turn off the power of the electric heating cooking device and wait for the device to cool down.

[0083] Next, first pull the heating module 2 along the extension direction of the second insertion section 1013, so that the conductive pin 203 disengages from between the two clamping pieces 1021 (see Figure 4 ), and then pull the heating module 2 along the first direction to separate it from the device main body 1; Finally, take out the heating module 2 for cleaning or maintenance.

[0084] Next, the installation process of the electric heating cooking device according to the embodiment of the present invention will be described: First, put the cleaned heating module 2 into the first insertion section 1012 along the first direction, and then move the heating module 2 along the extension direction of the second insertion section 1013, so that the conductive pin 203 is clamped between the two clamping pieces 1021 until the sealing ring 204 touches the ejector rod 301 of the micro switch 3, and then turn on the power, and the electric heating cooking device can operate normally.

[0085] In one embodiment, the electric heating cooking device is preferably but not limited to an oven or an air fryer, etc.

[0086] In summary, the heating module 2 of the electric heating cooking device according to the embodiment of the present invention can be detached from the device main body 1 and directly washed 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.
