[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] This embodiment provides an oven that can improve the convenience of the oven and enhance the ease of use and user experience.

[0054] like Figures 1 to 3 As shown, the oven provided in this embodiment includes a baking tray 1, a first base 2, a power control module, and a second base 3. The baking tray 1 has an internal heating element, a first electrical connector 14 on the lower side of its first end, and an oil drain channel 171 extending vertically through its second end. The first electrical connector 14 is electrically connected to the heating element. The power control module is mounted on the first base 2 and has a second electrical connector 4 extending above the first base 2. The second electrical connector 4 is detachably electrically connected to the first electrical connector 14. The second base 3 is separate from the first base 2 and has an oil collection chamber 51 inside. When the oven is assembled, the two ends of the baking tray 1 are supported by the first base 2 and the second base 3, respectively. The first electrical connector 14 and the second electrical connector 4 are electrically connected, and the oil drain channel 171 communicates with the oil collection chamber 51.

[0055] The oven provided in this embodiment, by setting up a separate first base 2, a second base 3, and a baking tray 1, allows the baking tray 1 to be supported on the upper sides of the first base 2 and the second base 3 respectively when the oven is assembled and in normal use. The first electrical connector 14, the second electrical connector 4, and the heating element are sequentially connected to heat the baking tray 1. At the same time, the oil produced during cooking can be discharged into the oil collection chamber 51 through the oil drain channel 171, meeting the normal use requirements of the oven. Since the first base 2 and the second base 3 are set up separately, the overall size and weight of the base structure formed by the combination of the first base 2 and the second base 3 are small. The first base 2 and the second base 3 can be transported and stored separately, thereby effectively reducing the overall weight of the oven and improving its portability and ease of use. Furthermore, by setting the power control module and the oil collection chamber 51 on the first base 2 and the second base 3 respectively, it is possible to avoid damage to the power control module by the oil produced during cooking, reduce the possibility of structural interference, and improve the rationality of the structural layout.

[0056] To improve the stability of the oven, the lower end of the first base 2 is provided with a first support leg 221, and at least three first support legs 221 are spaced apart. The lower end of the second base 3 is provided with a second support leg 321, and at least three second support legs 321 are spaced apart. Thus, the first support leg 221 provides support for the first base 2 on the bearing surface, and the second support leg 321 provides support for the second base 3 on the bearing surface.

[0057] To improve the stability of the baking tray 1, in one embodiment, the upper side of the first base 2 is recessed downwards to form a first receiving groove 211, and the upper side of the second base 3 is recessed downwards to form a second receiving groove 3111. The first receiving groove 211 and the second receiving groove 3111 have opposing side openings. When the oven is in the assembled state, the lower sides of both ends of the baking tray 1 are respectively received in the first receiving groove 211 and the second receiving groove 3111, thereby improving the stability of the baking tray 1 on the first base 2 and the second base 3, and also preventing the baking tray 1 from protruding too much from the first base 2 and the second base 3, which would affect the use and handling of the oven. The second electrical connector 4 is installed at the bottom of the receiving groove.

[0058] In one embodiment, the two ends of the baking pan 1 along its length are arc-shaped structures with openings facing each other, in order to increase the upper surface area of ​​the baking pan 1 while avoiding the overall size of the baking pan 1 being too large. The shapes of the first receiving groove 211 and the second receiving groove 3111 are respectively adapted to the shapes of the two ends of the baking pan 1. In other embodiments, the baking pan 1 may also adopt a rectangular disc structure.

[0059] Furthermore, the outer contours of the first base 2 and the second base 3 projected onto the horizontal projection plane are both D-shaped contours, so that the overall shape of the first base 2 and the second base 3 matches the shape of both ends of the baking tray 1, which facilitates the setting of the first receiving groove 211 and the second receiving groove 3111, while making the overall structure of the oven more compact.

[0060] The maximum length of the baking tray 1 in the longitudinal direction is L. When the oven is in the assembled state, the distance between the first base 2 and the second base 3 is d, where 0.2L ≤ d ≤ 0.6L. This arrangement, while ensuring the stability of the baking tray 1, reduces the size of the first base 2 and the second base 3, thereby reducing the overall weight of the oven and lowering its cost. Further, 0.35L ≤ d ≤ 0.55L.

[0061] like Figures 2 to 5 As shown, to further improve the installation stability of the baking tray 1 on the first base 2 and the second base 3, both the first base 2 and the second base 3 are recessed downwards to form installation grooves, and the bottom of the baking tray 1 is provided with a downward-protruding installation boss 121, which corresponds one-to-one with the installation groove. When the oven is in the assembled state, the installation boss 121 is inserted and engaged with the corresponding installation groove, thereby further realizing the installation positioning of the baking tray 1, the first base 2 and the second base 3.

[0062] For ease of subsequent description, the mounting groove on the first base 2 is defined as the first mounting groove 212, and the mounting groove on the second base 3 is defined as the second mounting groove 3112. The bottom of the first receiving groove 211 is recessed downward to form the first mounting groove 212, and the bottom of the second receiving groove 3111 is recessed downward to form the second mounting groove 3112.

[0063] The first base 2 and the second base 3 are each provided with two mounting grooves. The bottom of the baking tray 1 is provided with four mounting bosses 121. The four mounting bosses 121 are arranged in a rectangular pattern, which can improve the reliability of installation and positioning, and enhance the stability and reliability of the baking tray 1.

[0064] Furthermore, two first mounting grooves 212 are provided near the side openings of the first receiving groove 211 and are respectively provided on opposite sides of the first receiving groove 211 along the width direction of the baking tray 1, so as to increase the spacing between the two first mounting grooves 212; two second mounting grooves 3112 are provided near the side openings of the second receiving groove 3111 and are respectively provided on opposite sides of the second receiving groove 3111 along the width direction of the baking tray 1.

[0065] Both the first electrical connector 14 and the oil drain channel 171 are located outside the area enclosed by the four mounting bosses 121. In the width direction of the baking tray 1, the first electrical connector 14 is located between two mounting bosses 121. This avoids interference between the first electrical connector 14 and the mounting bosses 121, while also increasing the spacing between the two mounting bosses 121 spaced apart in the width direction of the baking tray 1, thereby improving the installation stability and reliability of the baking tray 1 on the first base 2 and the second base 3.

[0066] The mounting boss 121 is preferably a tapered boss that is larger at the top and smaller at the bottom, and the mounting groove is a tapered groove. This makes the mounting boss 121 fit more tightly when inserted into the mounting groove, improving the ease of taking out and putting in the baking tray 1 and the stability after installation.

[0067] In one embodiment, the upper side of the first base 2 has a first protruding ring 213 arranged around the mounting groove, and the upper end of the second base 31 has a second protruding ring 3114 arranged around the mounting groove. When the oven is in the assembled state, the first protruding ring 213 and the second protruding ring 3114 both abut against the bottom surface of the baking tray 1. By setting the first protruding ring 213 and the second protruding ring 3114, it is possible to control the distance between the bottom surface of the baking tray 1 and the bottom of the corresponding first receiving groove 211 and second receiving groove 3111 by controlling the protrusion height of the first protruding ring 213 and the second protruding ring 3114. This avoids the problem of the first electrical connector 14 and the second electrical connector 4 becoming more difficult to cooperate due to direct contact between the bottom of the first receiving groove 211 and the second receiving groove 3111. At the same time, this setting is conducive to ensuring that the first protruding ring 213 and the second protruding ring 3114 are set at the same height by processing and controlling the protrusion height of the first protruding ring 213 and the second protruding ring 3114, thereby ensuring the stability and reliability of the baking tray 1 on the first base 2 and the second base 3, and also reducing the overall structural requirements of the first base 2 and the second base 3.

[0068] The baking pan 1 includes a pan body 11 and a heat insulation cover 12. The upper side of the pan body 11 has a food-bearing surface. The heat insulation cover 12 is installed on the lower side of the pan body 11 and forms a sealed mounting cavity around the pan body 11. An electric heating element is installed within this mounting cavity. A first electrical connector 14 is installed at the bottom of the pan body 11 and extends through the heat insulation cover 12, so that the first electrical connector 14 is exposed at the bottom of the baking pan 1 for connection with a second electrical connector 4. Furthermore, a mounting boss 121 protrudes downwards from the bottom of the heat insulation cover 12.

[0069] By setting a heat insulation cover 12 at the bottom of the pan body 11, and the heat insulation cover 12 and the pan body 11 forming a sealed installation cavity, the heating element is set in the installation cavity, which prevents water, oil or other impurities from acting on the heating element, thereby protecting the heating element, improving the reliability of the heating element, and facilitating the cleaning and maintenance of the baking pan 1. Furthermore, the setting of the heat insulation cover 12 can also provide better support for the pan body 11, improve the overall structural strength and rigidity of the baking pan 1, reduce the probability of the baking pan 1 deforming due to heat, and at the same time reduce the conduction of heat generated by the heating element to the base, avoiding the risk of heat accumulation at the base that could burn the user, and improving the convenience for the user to take the baking pan 1 out.

[0070] The heating element includes a thick-film circuit 13, which has multiple heating devices dispersed at the bottom of the pan 11. Each heating device can generate heat after being energized, and the heat generated by each heating device radiates upwards and covers part of the food-bearing surface. This ensures that the heat radiation area formed by all the heating devices in the thick-film circuit 13 can roughly cover the entire food-bearing area, improving the heating uniformity of the food-bearing surface. By setting the heating element as a thick-film circuit 13, it is advantageous to set multiple discrete heating devices to improve the heating uniformity of the food-bearing surface. At the same time, using a thick-film circuit 13 as the heating element can reduce the footprint of the heating element, improve the overall structural compactness of the baking pan 1, and reduce the size and weight of the baking pan 1. In other embodiments, the heating element can be a heating wire laid at the bottom of the pan 11, a heating tube installed at the bottom of the pan 11, or other types of heating elements.

[0071] It is worth noting that the way the thick film circuit 13 is set on the disk body 11 can be referred to the existing technology. This is not the focus of this utility model and will not be described in detail here.

[0072] like Figure 3 , Figures 6 to 10 As shown, in one embodiment, the first electrical connector 14 includes a first connector 142, which is electrically connected to the heating element. The second electrical connector 4 includes a second connector 41. The first connector 142 and the second connector 41 are plugged in and out, meaning one of the first connector 142 and the second connector 41 is a female connector, and the other is a male connector. The male and female connectors are plugged in and out to improve the ease of assembly and disassembly and the stability of the connection, thereby ensuring the stability and reliability of information transmission. In other embodiments, the first electrical connector 14 and the second connector may also be electrically connected.

[0073] The first electrical connector 14 also includes a mounting base 141. An installation opening is provided on the heat insulation cover 12. The mounting base 141 covers the installation opening and is connected to both the heat insulation cover 12 and the disc 11. The first connector 142 is connected to the mounting base 141 and passes through the installation opening to extend into the mounting cavity. Further, the first connector 142 includes a first socket 1421 and a pin assembly. The pin assembly includes two conductive pins 1422. The first socket 1421 is connected to the mounting base 141 and has a lower open insertion groove. The conductive pins 1422 are installed at the bottom of the insertion groove and extend above the first pin. The two conductive pins 1422 are electrically connected to the two ends of the corresponding heating element. The second connector 41 includes a second socket 411 and a conductive contact 412. The second socket 411 is installed on the first base 2 and has an upper open socket. The socket, conductive contact 412, and conductive pin 1422 are arranged in a one-to-one correspondence. The conductive contact 412 is installed inside the socket. When the oven is in the assembled state, the conductive pin 1422 is inserted into the socket and makes electrical contact with the conductive contact 412.

[0074] In one embodiment, the disc body 11 has two heating areas arranged side by side, each heating area is provided with an electric heating element, and there are two sets of pins. All conductive pins 1422 are arranged side by side and spaced apart along the width direction of the first base 2. In other embodiments, there can be one, three or more heating areas, and the number of sets of conductive pins 1422 corresponds to the number of heating areas.

[0075] The first connector 142 also includes a spring group, which includes three conductive springs 1423. The spring groups are arranged one-to-one with the pin groups, and the first ends of the two conductive springs 1423 in each spring group are respectively connected to the two conductive pins 1422 in the pin group, and the second ends of the two conductive springs 1423 respectively abut against the two ends of the thick film circuit 13 to ensure the stability and reliability of the electrical connection. All conductive springs 1423 are spaced apart along the length of the first base 2 to improve the regularity of the arrangement and the compactness of the structure.

[0076] In one embodiment, the first socket 1421 and the mounting base 141 are integrally formed to reduce assembly difficulty. In other embodiments, the first socket 1421 is detachably mounted on the first base 21.

[0077] In one embodiment, the mounting base 141 includes a main base portion 1411, which is an elongated strip structure extending along the width direction of the first base 2. Fixing ears 1412 extend outward from both ends of the main base portion 1411. A mounting post portion 1413 protrudes from the upper side of the main base portion 1411. The fixing ears 1412 are mounted on the outside of the heat insulation cover 12 and fastened to the heat insulation cover 12 using a first fastener 18. The mounting post portion 1413 extends into the mounting cavity through a mounting opening and is fastened to the disc body 11 using a second fastener 19. This ensures the stability and reliability of the mounting base 141.

[0078] To reduce the probability of heat leakage from the mounting cavity through the mounting port, in one embodiment, the baking tray 1 further includes a sealing ring 15. The sealing ring 15 is arranged around the mounting port and sandwiched between the mounting base 141 and the heat insulation cover 12 to seal the assembly gap between the mounting base 141 and the heat insulation cover 12, thereby preventing heat leakage and also preventing moisture, oil, etc. from entering the mounting cavity and affecting the reliable use of the first electrical connector 14.

[0079] In one embodiment, the baking tray 1 further includes a support ring 16. The support ring 16 is arranged around the mounting opening and sandwiched between the heat insulation cover 12 and the tray body 11. The support ring 16 prevents the heat insulation cover 12 from being recessed in the direction towards the tray body 11, ensuring the structural strength and rigidity of the baking tray 1 at the mounting position of the first electrical connector 14, thereby ensuring the stability and reliability of the first electrical connector 14 and improving the connection reliability of the first electrical connector 14 and the second electrical connector 4. The support ring 16 is preferably made of ceramic or other heat-insulating materials to reduce the heat transferred from the thick film circuit 13 to the heat insulation cover 12 and improve the safety of the baking tray 1 in use.

[0080] In one embodiment, the support ring 16 has limiting grooves at both ends, and two first fasteners 18 are inserted into the limiting grooves to restrict the movement of the support ring 16 along the width direction of the first base 21. This ensures the stability of the support ring 16 while also avoiding the need to use other fasteners to fasten the support ring 16.

[0081] To detect cooking temperature, in one embodiment, the oven also includes a thermocouple mounted on the back of the pan 11 and electrically connected to the first electrical connector 14. Specifically, a probe connection assembly is mounted on the first base 21, with each probe connection assembly corresponding to a thermocouple. Each probe connection assembly includes two probe pins 143, and the two terminals of the thermocouple are connected to the two probe pins 143 to connect the thermocouple to the detection circuit. By integrating the first connector 142 and the probe pins 143 onto the mounting base 141, the integration of the first electrical connector 14 is improved, its size is reduced, and its footprint is minimized.

[0082] The second electrical connector 4 includes a contact group, which is configured one-to-one with the probe connection group. The contact group includes two probe contacts 42, the upper ends of which extend out of the upper side of the second base 3. When the oven is in the assembled state, the two probe pins 143 of the probe connection group contact the two probe contacts 42 of the corresponding contact group to achieve electrical conduction.

[0083] In one embodiment, two heating zones and two thermocouples are provided, with each probe connection group corresponding to a thermocouple. The mounting base 141 has a long strip structure, with the first connector 142 located in the middle of the mounting base 141 along its length. The two probe connection groups are located at opposite ends of the first connector 142 along its length. This arrangement helps to reduce the overall size of the first electrical connector 14, improves the ease of installation of the first electrical connector 14 on the disc 11, and reduces the footprint. At the same time, placing the first connector 142 in the middle of its length facilitates force balance during insertion and removal. Placing the two probe connection groups on opposite sides of the first connector 142 facilitates the connection of the two electrical lines and the two thermocouples with the first electrical connector 14, reduces wiring interference, and improves wiring convenience.

[0084] To improve the connection reliability of the first electrical connector 14 and the second electrical connector 4, a positioning groove 215 is recessed downward on the upper side of the first base 2, and a positioning boss 1414 is protruding downward on the mounting body 141, surrounding the first connector 142. When the oven is in the assembled state, the positioning boss 1414 is inserted into the positioning groove 215 to further guide the insertion and removal of the first connector 142 and the second connector 41, thereby improving the connection reliability of the first electrical connector 14 and the second electrical connector 4.

[0085] In one embodiment, both the second connector 41 and the contact assembly are mounted on the first base 2, meaning that a portion of the structure of the first base 2 forms the seat structure of the first electrical connector 14. This reduces the number of oven components and further lightens the oven's weight. In other embodiments, the second electrical connector 4 includes a fixed seat mounted on the first base 2, with both the second connector 41 and the contact assembly mounted on the fixed seat.

[0086] Furthermore, the second base 31 has an upwardly raised insertion boss 214, which has a lowerly open receiving cavity and multiple insertion ports at its upper end. The second connector 41 is installed in the receiving cavity, with the socket and insertion port corresponding one-to-one. When the oven is in the assembled state, the insertion boss 214 is inserted into the insertion groove, and the conductive pin 1422 passes through the insertion port and is inserted into the socket.

[0087] like Figures 9 to 11As shown, the second electrical connector 4 also includes an adapter plate 43, which is installed inside the second base 3 and is arranged in a one-to-one correspondence with the contact group. The lower end of the probe contact 42 passes through the bottom of the first receiving groove 211 and is welded to the adapter plate 43. This improves the convenience of connecting the probe contact 42 to the power supply.

[0088] In one embodiment, a control panel 6 is provided at the upper end of the first base 2. The control panel 6 is disposed along the outer edge of the first base 2 and is electrically connected to the power control module. When the oven is in the assembled state, the control panel 6 is disposed around the outer side of the baking tray 1 so that the user can control the heating of the baking tray 1 through the control panel 6.

[0089] To improve the ease of disassembly and replacement of the internal structure of the first base 2, the first base 2 includes a first body 21 and a first bottom cover 22. The first body 21 has a mounting groove with an open bottom. The first bottom cover 22 is detachably installed at the lower end of the first body 21 and seals the opening of the mounting groove. This allows for the disassembly, repair, and replacement of the internal structure of the first base 21 by removing the first bottom cover 22 relative to the first body 21. The power control module and control panel 6 are both installed on the first body 21. The first bottom cover 22 is provided with a first support leg 221; specifically, the first bottom cover 22 is pressed downwards to form the first support leg 221.

[0090] like Figures 12 to 14 As shown, in one embodiment, the oven also includes an oil collection box 5, which is horizontally pullable inside the second base 3. The upper end of the second base 3 has an oil drain port 3113. When the oven is assembled, the oil drain channel 171 communicates with the oil collection chamber 51 through the oil drain port 3113. By providing a pull-out oil collection box 5, it is convenient to clean and place the oil collection box 5 by removing and placing it, thus improving the user experience of the oven. In other embodiments, the oil collection chamber 51 can also be directly provided on the second base 3.

[0091] The second seat 31 has an annular protrusion 3115 on its upper side surrounding the oil drain 3113. The annular protrusion 3115 abuts against the bottom surface of the baking pan 1 to better support the baking pan 1 and improve the stability of the baking pan 1.

[0092] In one embodiment, the baking pan 1 further includes an oil drain pipe 17. The upper end of the oil drain pipe 17 is open and extends through the bearing surface of the baking pan 1 to form an oil inlet. The lower end of the oil drain pipe 17 extends downwards out of the lower side of the baking pan 1. When the oven is in the assembled state, the lower end of the oil drain pipe 17 extends into the oil drain port 3113, thereby facilitating the guidance of oil into the oil collection chamber 51 and reducing the probability of oil flowing to other locations. Specifically, the upper end of the pan body 11 has a first hole, and the heat insulation cover 12 has a second hole. The first hole and the second hole are directly opposite each other. The upper end of the oil drain pipe 17 is inserted into the first hole and welded to the pan body 11. The oil drain pipe 17 passes through the second hole and is welded to the heat insulation cover 12 or has an interference fit with the second hole.

[0093] The second base 3 has a pull-out opening 3121 on the side away from the first base 2. The oil collection box 5 is pull-out mounted on the second base 3 through the pull-out opening 3121, thereby avoiding interference between the pull-out of the oil collection box 5 and the first base 2, and improving the convenience of taking out and putting in the oil collection box 5. In other embodiments, the pull-out opening 3121 may be provided on other sides of the second base 3.

[0094] To improve the ease of setting up the oil collection box 5, in one embodiment, the inner cavity of the second base 3 is divided into a limiting cavity 33, and the oil collection box 5 can be pulled out and set in the limiting cavity 33. The shape of the limiting cavity 33 is adapted to the shape of the oil collection box 5, so that when the oil collection box 5 is placed in the limiting cavity 33, the oil collection box 5 is limited in the limiting cavity 33, thereby improving the stability and reliability of setting up the oil collection box 5.

[0095] In one embodiment, the second base 3 includes a second seat body 31 and a second bottom cover 32. The second bottom cover 32 is detachably installed at the lower end of the second seat body 31 and forms a limiting cavity 33 with the second seat body 31. This type of second base 3 has a simple structure, is easy to process, and facilitates the realization of a hollow structure inside the second seat body 31 to reduce the weight of the second seat body 31. The second bottom cover 32 is provided with a second support leg 321. Specifically, the second bottom cover 32 is pressed downward to form the second support leg 321.

[0096] The second seat 31 includes a seat top 311 and a side edge 312 surrounding the periphery of the seat top 311. A connecting post 314 extends downward from the lower side of the seat top 311. The connecting post 314 is located near the side edge 312 and is spaced out in multiple positions along the circumference of the side edge 312. The second bottom cover 32 abuts against the lower end of the connecting post 314, and the second bottom cover 32 and the connecting post 314 are fastened together by fasteners passing through both. Further, the seat top 311 is recessed downward to form a second receiving groove 3111, and the bottom of the second receiving groove 3111 is punched downward to form a mounting groove.

[0097] A rib plate 313 protrudes from the lower side of the top of the seat 311. The outer contour of the second bottom cover 32 is adapted to the outer contour of the top of the seat 311. The lower end of the rib plate 313 abuts against the second bottom cover 32. The rib plate 313, the second bottom cover 32 and the top of the seat 311 form a limiting cavity 33.

[0098] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0099] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
