Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of kitchen appliances, and particularly relates to a frying and baking machine. BACKGROUND

[0002] At present, frying and baking machines are widely used in people's life, and can heat food on both sides at the same time, and are commonly used for frying or baking food. When consumers choose frying and baking machines, frying and baking machines with detachable baking trays are more popular, because the detachable design of the baking tray can facilitate users to detach the baking tray for thorough cleaning.

[0003] In the cooking operation of the frying and baking machine, the temperature of the baking tray needs to be measured in real time to adjust the heating device in real time to achieve better cooking effect. However, for the frying and baking machine with a detachable baking tray, the temperature controller cannot be fixed with the baking tray, but is elastically connected to the base to realize the elastic movement of the temperature controller in the vertical direction. During use, the temperature controller is compressed downward along the vertical direction by the gravity of the baking tray after the baking tray is placed, and then contacts the baking tray and senses the temperature of the baking tray. In the prior art, in order to facilitate the detachment and placement of the baking tray, a sufficient gap is reserved between the baking tray and the base in the circumferential direction, but the existence of the gap allows the baking tray to shake in the circumferential direction of the base after the baking tray is placed on the base. During the shaking process, the temperature controller is also driven in the corresponding direction, and then the side of the temperature sensing surface of the temperature controller contacts the base. The temperature on the base is transmitted to the temperature controller through the side of the temperature sensing surface of the temperature controller, which affects the temperature sensing sensitivity of the temperature controller and then affects the temperature control accuracy. Moreover, when the temperature controller is deviated to the side under the driving of the baking tray, the elastic movement of the temperature controller in the vertical direction is affected by the friction or jamming with the base, and in severe cases, the temperature controller is stuck and cannot realize the elastic movement in the vertical direction, thereby affecting the temperature measurement. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a frying and baking machine to solve the technical problem that the temperature controller of the existing frying and baking machine with a detachable baking tray shakes under the driving of the baking tray during the installation of the baking tray, and the contact surface of the temperature controller deviates from the temperature sensing surface, thereby affecting the accuracy of temperature measurement and the smoothness of the elastic movement of the temperature controller.

[0005] The technical solution adopted by the present application is as follows:

[0006] The application discloses a kind of fryers, including base and grill plate detachably mounted to the base, the base is equipped with heating device for heating the grill plate, the base is equipped with mounting seat and jump temperature controller that can float in the mounting seat, the heating device is equipped with temperature measuring hole for the jump temperature controller to float up and down to be attached to the grill plate, the outer periphery of the jump temperature controller is equipped with limiting convex part, the limiting convex part extends along the radial direction of the temperature measuring hole, the heating device and / or the mounting seat are equipped with limiting rib, the limiting rib forms limiting sleeve extending along the axial direction of the temperature measuring hole, the limiting convex part is located in the limiting sleeve and slides against the inner wall of the limiting sleeve to limit the wobble of the jump temperature controller in the temperature measuring hole.

[0007] The outer periphery of the jump temperature controller in the application is equipped with limiting convex part extending along the radial direction of the temperature measuring hole, and limiting rib capable of limiting the limiting convex part is arranged on the heating device and / or the mounting seat, so that even if the assembly gap between the grill plate and the base is increased for the convenience of detachable grill plate, the jump temperature controller will not wobble greatly along the radial direction of the temperature measuring hole during the assembly of the grill plate, ensuring that the temperature sensing surface of the jump temperature controller can maintain surface-to-surface contact with the grill plate during temperature measurement, so that the jump temperature controller can better receive heat, improve the sensitivity of the action of the bimetallic strip in the jump temperature controller, thereby ensuring the timeliness and accuracy of temperature measurement, improving the response speed of the jump temperature controller, making the control of the control unit on the heating device more accurate, and thus ensuring the cooking effect. Moreover, by limiting the wobble of the jump temperature controller in the temperature measuring hole, the wear between the jump temperature controller and the grill plate can be reduced during the disassembly and assembly of the grill plate, thereby prolonging the service life of the jump temperature controller. In addition, the limiting convex part slides against the inner wall of the limiting sleeve, which can limit the displacement of the jump temperature controller in the radial direction, so that the friction with the inner wall of the temperature measuring hole can be reduced during the movement of the jump temperature controller in the axial direction of the temperature measuring hole, avoiding the jump temperature controller from being stuck, ensuring the elastic movement of the jump temperature controller in the axial direction of the temperature measuring hole, and thus ensuring the normal temperature measurement.

[0008] The heating device includes a fixed disc and a heating pipe arranged on the fixed disc, and the limiting rib is arranged on the side of the fixed disc away from the grill plate.

[0009] If the limiting rib is arranged on the side of the fixed disc facing the grill plate, a large gap will exist between the part of the fixed disc without the limiting rib and the grill plate, resulting in a decrease in heating efficiency. In the technical solution, the limiting rib is arranged on the side of the fixed disc away from the grill plate, which can reduce the gap size between the fixed disc and the grill plate and achieve contact heat transfer between the fixed disc and the grill plate as much as possible, thereby improving the heating efficiency.

[0010] The jump temperature controller is provided with a positive terminal, a negative terminal, a ground terminal and a temperature sensing surface capable of being attached to the baking tray, and the position height of the ground terminal on the jump temperature controller is between the position height of the positive terminal on the jump temperature controller and the position height of the temperature sensing surface on the jump temperature controller.

[0011] The grilling machine needs a large power to provide enough heat during work, so the operation of the grilling machine needs to use strong electricity to meet its power demand. The jump temperature controller is an overheat protection element of the grilling machine, which can quickly cut off the power supply when the measured temperature exceeds the set value, so as to prevent the grilling machine from overheating and affecting its service life. The jump temperature controller in the technical solution can be contacted with the outside through the temperature measuring hole, and the residual water after the baking tray is disassembled and cleaned and the water stains and dirt of the outside during use may contact the jump temperature controller through the temperature measuring hole. Therefore, the jump temperature controller in the technical solution can guide the current to the ground through the ground wire through the additional ground terminal, so as to avoid the damage caused by voltage overload or electrical failure due to abnormal conditions. Moreover, the ground terminal is arranged between the positive terminal and the temperature sensing surface, which helps to quickly guide the fault current to the ground when an electrical fault occurs (such as insulation damage or electric leakage), thereby reducing the risk of electric shock and the possibility of damage to the grilling machine.

[0012] The limiting ribs are circumferentially spaced apart along the outer periphery of the jump temperature controller, and a channel is formed between two of the limiting ribs for the ground terminal to extend out of.

[0013] In the technical solution, a plurality of limiting ribs are arranged, and a channel is formed between two of the limiting ribs for the ground terminal to extend out of, so as to facilitate the electrical connection of the contact point of the ground terminal. Such design can simplify the structural design of the fixing disc and reduce the processing difficulty of the fixing disc. Moreover, the space formed between the two limiting ribs can provide explicit guidance for the installation of the jump temperature controller during assembly of the jump temperature controller, thereby improving the assembly efficiency of the jump temperature controller.

[0014] The mounting seat is provided with a mounting cavity for accommodating the jump temperature controller, and the mounting cavity has an opening facing the temperature measuring hole, and the limiting ribs are arranged on the outer periphery of the opening and extend along the axial direction of the mounting cavity towards the heating device.

[0015] In the technical solution, the mounting cavity on the mounting seat can provide primary radial limitation for the jump temperature controller, and the limiting ribs arranged on the outer periphery of the opening of the mounting cavity can provide further radial limitation for the jump temperature controller, so as to further improve the radial limitation effect of the jump temperature controller and prevent it from shaking along the radial direction of the temperature measuring hole under external force.

[0016] The jump temperature controller is provided with a positive terminal, a negative terminal, a ground terminal and a temperature sensing surface capable of being attached to the baking tray, the ground terminal is located between the position height of the positive terminal on the jump temperature controller and the position height of the temperature sensing surface on the jump temperature controller, the side wall of the mounting cavity is provided with a first sliding groove for the positive terminal and the negative terminal to float, and the limiting rib is provided with a second sliding groove in communication with the first sliding groove and a third sliding groove for the ground terminal to float.

[0017] In the technical solution, the first sliding groove and the second sliding groove can provide a space for the positive terminal and the negative terminal to float and move, and can also facilitate the positive terminal and the negative terminal to externally connect the circuit through the first sliding groove and the second sliding groove respectively. The third sliding groove can provide a space for the ground terminal to float and move, and can also facilitate the ground terminal to externally connect the circuit. In addition, the first sliding groove, the second sliding groove and the third sliding groove provide a heat dissipation channel for the jump temperature controller, reduce the temperature rise in the mounting cavity, and make the jump temperature controller in a relatively suitable environment temperature, thereby prolonging the service life of the jump temperature controller.

[0018] The jump temperature controller has a temperature measuring position attached to the baking tray and an initial position floating out of the temperature measuring hole, and the depth of the third sliding groove is greater than or equal to the floating stroke of the jump temperature controller switching from the temperature measuring position to the initial position, so as to prevent the ground terminal from being detached from the third sliding groove.

[0019] The depth of the third sliding groove is limited to be greater than or equal to the floating stroke of the jump temperature controller switching from the temperature measuring position to the initial position, so as to prevent the ground terminal from being detached from the third sliding groove when floating with the jump temperature controller, thereby ensuring the stability of the installation position of the jump temperature controller, so that it can still remain at the preset position of the mounting cavity in the repeated floating process, avoiding the difficulty of returning due to detachment and the jamming phenomenon due to deviation from the preset position.

[0020] The jump temperature controller is provided with a positive terminal, a negative terminal and a ground terminal, one end of the ground terminal is fixedly connected with the limiting protrusion, and the other end extends away from the limiting protrusion.

[0021] The ground terminal is fixedly connected with the limiting protrusion and extends outward, which can ensure that the connection between the ground terminal and the jump temperature controller is more stable, so that the connection between the ground terminal and the jump temperature controller is not easily damaged in a mechanical impact or vibration environment, thereby improving the durability of the jump temperature controller.

[0022] The limiting protrusion extends continuously along the circumference of the snap-action temperature controller to form a limiting ring; the limiting rib extends continuously along the periphery of the limiting ring, or multiple limiting ribs are spaced apart along the outer periphery of the limiting ring.

[0023] In this technical solution, the limiting protrusion extends continuously along the circumference of the snap-action temperature controller, allowing the limiting protrusion to make multi-point contact with the limiting rib. Regardless of how the baking tray is placed or offset towards the preset installation position on the base after disassembly, the limiting protrusion can abut against the limiting rib to limit the radial sway of the snap-action temperature controller along the temperature measuring hole. This improves the limiting effect of the limiting rib on the limiting protrusion, ensuring that the snap-action temperature controller floats along the preset position, thereby ensuring the stability and accuracy of the temperature measurement by the snap-action temperature controller.

[0024] The snap-on temperature controller has a temperature measuring position that fits against the baking pan and an initial position that floats out of the temperature measuring hole. The mounting base is provided with an elastic element for driving the snap-on temperature controller to switch from the temperature measuring position to the initial position.

[0025] This technical solution incorporates an elastic element on the mounting base that drives the snap-action thermostat to switch from the temperature measurement position to its initial position. This allows the thermostat to smoothly return to its initial position after the baking tray is removed, ready for the next contact with the tray for temperature measurement. Especially with prolonged use, the baking tray may deform due to various reasons. The thermostat's smooth return ensures that even if the area directly opposite the baking tray deforms, the thermostat remains in contact with it for temperature measurement, guaranteeing normal operation.

[0045] As shown in Figures 1 to 5 A grilling machine includes a base 21 and a grill plate 22 detachably mounted on the base 21, the base 21 is provided with a heating device 3 for heating the grill plate 22, the base 21 is provided with a mounting seat 5 and a bump temperature controller 4 floatingly arranged in the mounting seat 5, the heating device 3 is provided with a temperature measuring hole 33 for the bump temperature controller 4 to float up and down to adhere to the grill plate 22, the outer periphery of the bump temperature controller 4 is provided with a limiting protrusion 41, the limiting protrusion 41 extends in a direction parallel to the radial direction of the temperature measuring hole 33, the heating device 3 and / or the mounting seat 5 is provided with a limiting rib 6, the limiting rib 6 forms a limiting sleeve extending in the axial direction of the temperature measuring hole 33, and the limiting protrusion 41 is located in the limiting sleeve and slides against the inner wall of the limiting sleeve to limit the shaking of the bump temperature controller 4 in the temperature measuring hole 33.

[0046] Generally, the grilling machine includes an upper grill plate assembly 1 and a lower grill plate assembly 2, the upper grill plate assembly 1 and the lower grill plate assembly 2 are pivotally connected through a hinged device, the upper grill plate assembly 1 includes an upper cover and an upper grill plate arranged on the upper cover, and the lower grill plate assembly 2 includes a base and a lower grill plate arranged on the base. The base 21 and the grill plate 22 detachably mounted on the base 21 in the present application can be the upper cover and the upper grill plate detachably mounted on the upper cover, or the base and the lower grill plate detachably mounted on the base. Therefore, Figure 2 and The specific example of using the bump temperature controller 4 to detect the temperature of the lower grill plate shown in Figure 3 does not limit the present application.

[0047] The outer periphery of the temperature jump controller 4 in the application is provided with a limiting protrusion 41 extending in a direction parallel to the radial direction of the temperature measuring hole 33, and a limiting rib 6 capable of limiting the limiting protrusion 41 is arranged on the heating device 3 and / or the mounting seat 5, so that even if the assembly gap between the baking tray 22 and the base 21 is increased for the convenience of disassembling the baking tray 22, the temperature jump controller 4 will not shake greatly along the radial direction of the temperature measuring hole 33 in the process of assembling the baking tray 22, ensuring that the temperature sensing surface 45 of the temperature jump controller 4 can maintain surface-to-surface contact with the baking tray 22 during temperature measurement, so that the temperature jump controller 4 can better receive heat, improve the sensitivity of the bimetallic strip action in the temperature jump controller 4, thereby ensuring the timeliness and accuracy of temperature measurement, improving the response speed of the temperature jump controller 4, so that the control unit can control the heating device 3 more accurately, thereby ensuring the cooking effect. Moreover, by limiting the shaking of the temperature jump controller 4 in the temperature measuring hole 33, the wear between the temperature jump controller 4 and the baking tray 22 can be reduced during the disassembly and assembly of the baking tray 22, thereby prolonging the service life of the temperature jump controller 4. In addition, the limiting protrusion 41 slides against the inner wall of the limiting sleeve, which can limit the displacement of the temperature jump controller 4 in the radial direction, thereby reducing the friction between the temperature jump controller 4 and the inner wall of the temperature measuring hole 33 during movement in the axial direction of the temperature measuring hole 33, avoiding the jamming of the temperature jump controller 4, ensuring the elastic movement of the temperature jump controller 4 in the axial direction of the temperature measuring hole 33, and thereby ensuring the normal operation of temperature measurement.

[0048] The structure of the limiting protrusion in the application can adopt any one of the following embodiments:

[0049] Embodiment one: as shown in Figure 4 and Figure 5 , the limiting protrusion 41 continuously extends along the circumference of the temperature jump controller 4 to form a limiting ring. The structure of the limiting rib 6 matched therewith can adopt any one of the following embodiments:

[0050] Embodiment 1: not shown in the embodiment 1, in the embodiment 1, the limiting rib continuously extends along the outer periphery of the limiting ring, so as to laterally abut against the limiting protrusion and limit the shaking of the temperature jump controller in the radial direction of the temperature measuring hole.

[0051] Embodiment 2: as shown in Figure 4 and Figure 5 , a plurality of limiting ribs 6 are arranged at intervals along the outer periphery of the limiting ring, so as to laterally abut against the limiting protrusion 41 and limit the shaking of the temperature jump controller 4 in the radial direction of the temperature measuring hole 33.

[0052] In this first embodiment, the limiting protrusion 41 extends continuously along the circumference of the snap-action temperature controller 4, thereby enabling the limiting protrusion 41 to make multi-point contact with the limiting rib 6. No matter how the baking tray 22 is placed or offset towards the preset installation position on the base 21 after disassembly, the limiting protrusion 41 can abut against the limiting rib 6 to limit the swaying of the snap-action temperature controller 4 along the radial direction of the temperature measuring hole 33. This improves the limiting effect of the limiting rib 6 on the limiting protrusion 41, ensuring that the snap-action temperature controller 4 floats along the preset position, thereby ensuring the stability and accuracy of the temperature measurement of the snap-action temperature controller 4.

[0053] Implementation Method Two: This implementation method two is not illustrated. In this implementation method two, multiple limiting protrusions are provided at intervals along the circumference of the snap-action temperature controller. The structure of the corresponding limiting ribs can adopt any of the following embodiments:

[0054] Example 3: The limiting rib extends continuously around the periphery of the snap-action thermostat so as to make lateral contact with the limiting protrusion and limit the snap-action thermostat from shaking in the radial direction of the temperature measuring hole.

[0055] Example 4: Multiple limiting ribs are provided around the periphery of the snap-action temperature controller. When the baking tray is removed, the projections of the limiting ribs and the limiting protrusions along the outer circumference of the snap-action temperature controller at least partially overlap, so as to be able to make lateral contact with the limiting protrusions and limit the swaying of the snap-action temperature controller along the radial direction of the temperature measuring hole.

[0056] The location of the limiting protrusion in this application can be any of the following embodiments:

[0057] Implementation Method 3: This implementation method is not illustrated. In this implementation method, the heating device includes a fixed plate and a heating tube disposed on the fixed plate. A limiting rib is disposed on the fixed plate, and at least a portion of the limiting rib protrudes from the side of the fixed plate facing the baking pan.

[0058] Implementation Method Four: (e.g.) Figures 2 to 5 As shown, the heating device 3 includes a fixed plate 31 and a heating tube 32 disposed on the fixed plate 31, and a limiting rib 6 is disposed on the side of the fixed plate 31 facing away from the baking tray 22.

[0059] If the arrangement in Embodiment 3 is adopted, a large gap will exist between the part of the fixed plate without the limiting rib and the baking plate, resulting in a decrease in heating efficiency. In this Embodiment 4, the limiting rib 6 is provided on the side of the fixed plate 31 facing away from the baking plate 22, which can reduce the gap size between the fixed plate 31 and the baking plate 22, and realize contact heat transfer between the fixed plate 31 and the baking plate 22 as much as possible, thereby improving heating efficiency.

[0060] The toaster needs a large power to provide enough heat when working, so the operation of the toaster needs to use strong electricity to meet its power demand. The snap temperature controller 4 is the overheat protection element of the toaster. When the temperature measured by the snap temperature controller 4 exceeds the set value, the power supply can be quickly cut off to prevent the toaster from overheating and affecting its service life. The snap temperature controller 4 in the present application can be in contact with the outside through the temperature measurement hole 33, and the residual water after the grill plate 22 is disassembled and cleaned and the water stains and dirt of the outside during use can all come into contact with the snap temperature controller 4 through the temperature measurement hole 33. Therefore, as a preferred embodiment of the present application, as shown in Figure 4 and Figure 5 The snap temperature controller 4 is provided with a positive terminal 43, a negative terminal 44, a ground terminal 42, and a temperature sensing surface 45 capable of being attached to the grill plate 22. The position height of the ground terminal 42 on the snap temperature controller 4 is between the position height of the positive terminal 43 on the snap temperature controller 4 and the position height of the temperature sensing surface 45 on the snap temperature controller 4. By adding the ground terminal 42, the current can be guided to the ground through the ground wire, which can avoid the damage caused by voltage overload or electrical failure due to abnormal conditions. Moreover, the ground terminal 42 is arranged between the positive terminal 43 and the temperature sensing surface 45, which helps to quickly guide the fault current to the ground when an electrical fault occurs (such as insulation damage or electric leakage), reducing the risk of electric shock and the possibility of damage to the toaster.

[0061] Preferably, the position height of the positive terminal 43 and the negative terminal 44 on the snap temperature controller 4 is the same, which can make the structure of the snap temperature controller 4 more symmetrical, helping to maintain the overall motion balance of the snap temperature controller 4, and on the other hand, the same height design of the two provides a consistent reference height during assembly, which is convenient for automatic assembly or manual installation and simplifies the assembly process.

[0062] The snap temperature controller 4 has a temperature measurement position attached to the grill plate 22 and an initial position floating out of the temperature measurement hole 33. As a preferred embodiment of the fourth embodiment, as shown in Figure 3 At the temperature measurement position, the distance between the bottom end of the limiting rib 6 and the ground terminal 42 is greater than or equal to the floating stroke of the snap temperature controller 4 from the temperature measurement position to the initial position. In this embodiment, by limiting the distance between the bottom end of the limiting rib 6 and the ground terminal 42 to be greater than or equal to the floating stroke of the snap temperature controller 4 from the temperature measurement position to the initial position, the distance between the limiting rib 6 and the ground terminal 42 can be large enough to ensure that the ground terminal 42 can always maintain good contact with the corresponding contact point during the floating of the snap temperature controller 4 from the temperature measurement position to the initial position, avoiding electrical failure caused by poor contact.

[0063] Further, as shown in Figure 4 and Figure 5As shown, the limiting ribs 6 are provided in multiple along the outer periphery of the bumping temperature controller 4, and a channel for the grounding terminal 42 to extend is formed between two limiting ribs 6. By providing multiple limiting ribs 6 and forming a channel for the grounding terminal 42 to extend between two limiting ribs 6, the electrical connection between the grounding terminal 42 and its contact point is facilitated, and the structure of the fixing disc 31 is simplified, and the processing difficulty of the fixing disc 31 is reduced. Moreover, the space between the two limiting ribs 6 can provide clear guidance for the installation of the bumping temperature controller 4 during the assembly of the bumping temperature controller 4, and the assembly efficiency of the bumping temperature controller 4 is improved.

[0064] Embodiment five: as Figure 6 As shown, the mounting seat 5 is provided with a mounting cavity 51 for accommodating the bumping temperature controller 4, the mounting cavity 51 has an opening facing the temperature measuring hole 33, and the limiting ribs 6 are arranged on the outer periphery of the opening and extend along the axial direction of the mounting cavity 51 towards the heating device 3. The provision of the mounting cavity 51 on the mounting seat 5 can provide primary radial limitation for the bumping temperature controller 4, and the limiting ribs 6 added on the outer periphery of the opening of the mounting cavity 51 can provide further radial limitation for the bumping temperature controller 4, so as to further improve the radial limitation effect of the bumping temperature controller 4 and prevent it from shaking along the radial direction of the temperature measuring hole 33 under external force.

[0065] As a preferred embodiment of the fifth embodiment, as Figure 6 As shown, the bumping temperature controller 4 is provided with a positive terminal 43, a negative terminal 44, a grounding terminal 42, and a temperature sensing surface 45 capable of being attached to the baking tray 22, the position height of the grounding terminal 42 on the bumping temperature controller 4 is between the position height of the positive terminal 43 on the bumping temperature controller 4 and the position height of the temperature sensing surface 45 on the bumping temperature controller 4, a first sliding groove 52 for the positive terminal 43 and the negative terminal 44 to float is formed on the side wall of the mounting cavity 51, and a second sliding groove in communication with the first sliding groove 52 and a third sliding groove for the grounding terminal 42 to float are formed on the limiting rib 6. The provision of the first sliding groove 52 and the second sliding groove can provide a space for the positive terminal 43 and the negative terminal 44 to float and a moving guide for the bumping temperature controller 4, and on the other hand, the positive terminal 43 and the negative terminal 44 can be conveniently connected to the external circuit through the first sliding groove 52 and the second sliding groove respectively. The provision of the third sliding groove can provide a space for the grounding terminal 42 to float and a moving guide for the bumping temperature controller 4, and on the other hand, the grounding terminal 42 can be conveniently connected to the external circuit through the third sliding groove. In addition, the provision of the first sliding groove 52, the second sliding groove and the third sliding groove also provides a heat dissipation channel for the bumping temperature controller 4, reduces the temperature rise in the mounting cavity 51, makes the bumping temperature controller 4 in a relatively suitable environment temperature, and prolongs the service life of the bumping temperature controller 4.

[0066] Further, the jump temperature controller 4 has a temperature measuring position abutting against the baking tray 22 and an initial position floating out of the temperature measuring hole 33, and the third sliding groove has a depth greater than or equal to the floating stroke of the jump temperature controller 4 from the temperature measuring position to the initial position, so as to prevent the grounding terminal 42 from being detached from the third sliding groove. By limiting the depth of the third sliding groove to be greater than or equal to the floating stroke of the jump temperature controller 4 from the temperature measuring position to the initial position, the grounding terminal 42 can be prevented from being detached from the third sliding groove when floating with the jump temperature controller 4, so as to ensure the stability of the installation position of the jump temperature controller 4, and the jump temperature controller 4 can still be kept at the preset position of the installation cavity 51 during repeated floating, so as to avoid the difficulty of returning and the jamming phenomenon caused by deviating from the preset position.

[0067] As a preferred embodiment of the fifth embodiment, as shown in Figure 3 the jump temperature controller 4 has a temperature measuring position abutting against the baking tray 22 and an initial position floating out of the temperature measuring hole 33, and the mounting seat 5 is provided with an elastic member 53 for driving the jump temperature controller 4 from the temperature measuring position to the initial position. The elastic member 53 can be a spring, for example. By providing the elastic member 53 for driving the jump temperature controller 4 from the temperature measuring position to the initial position on the mounting seat 5, the jump temperature controller 4 can be smoothly returned to the initial position after the baking tray 22 is removed, so as to be ready for abutting against the baking tray 22 for temperature measurement next time. Especially, with the extension of the use time, the baking tray 22 can be deformed due to various reasons, and the jump temperature controller 4 can be smoothly returned, so that even if the part of the baking tray 22 directly opposite to the jump temperature controller 4 is deformed, the jump temperature controller 4 can still keep the state of abutting against the baking tray 22 for temperature measurement, so as to ensure the normal temperature measurement.

[0068] The sixth embodiment is not shown, and in the sixth embodiment, the heating device includes a fixed disc and a heating tube arranged on the fixed disc, the mounting seat is provided with an installation cavity for accommodating the jump temperature controller, the installation cavity has an opening facing the temperature measuring hole, and the fixed disc and the outer periphery of the opening on the mounting seat are both provided with a limiting rib.

[0069] As a preferred embodiment of the present application, the jump temperature controller 4 is provided with a positive terminal 43, a negative terminal 44, a grounding terminal 42, and a temperature sensing surface 45 capable of abutting against the baking tray 22. The specific arrangement position of the grounding terminal 42 can adopt any one of the following embodiments:

[0070] The fifth embodiment is not shown, and in the fifth embodiment, the position height of the grounding terminal on the jump temperature controller is between the position height of the temperature sensing surface and the position height of the limiting protrusion.

[0071] The sixth embodiment is not shown, and in the sixth embodiment, the heating device includes a fixed disc and a heating tube arranged on the fixed disc, the mounting seat is provided with an installation cavity for accommodating the jump temperature controller, the installation cavity has an opening facing the temperature measuring hole, and the fixed disc and the outer periphery of the opening on the mounting seat are both provided with a limiting rib. Figure 6As shown, one end of the grounding terminal 42 is fixedly connected with the limiting protrusion 41, and the other end extends towards the direction away from the limiting protrusion 41. By fixing the grounding terminal 42 with the limiting protrusion 41 and extending outward, the connection between the grounding terminal 42 and the bump-over temperature controller 4 can be ensured to be more stable, so that the connection between the grounding terminal 42 and the bump-over temperature controller 4 is not easy to be damaged in a mechanical impact or vibration environment, thereby improving the durability of the bump-over temperature controller 4.
