Since the temperature controller is arranged on the periphery of the heating element, the temperature of the use environment of the temperature controller is reduced, so that the insulating seat of the temperature controller can adopt a material with relatively low temperature resistance but low price, thereby saving cost, and the service life of the temperature controller can be prolonged.

Description

Technical Field

[0001] This application relates to the field of cooking appliances technology, and in particular to a grill. Background Technology

[0002] In a grill, the thermostat is a crucial component. It detects the temperature of the heating element and thus controls its operation. In current technology, the thermostat is typically located inside the heating element. The operating environment for thermostats is often high-temperature, and their insulating base is usually made of ceramic, resulting in higher costs. Furthermore, because thermostats operate in high-temperature environments for extended periods, their lifespan is relatively short. Utility Model Content

[0003] Therefore, it is necessary to provide a grill that can extend the lifespan of the thermostat.

[0004] This application provides a grilling machine, including a grill pan, a heating element, and a temperature controller. The heating element and the temperature controller are both located on one side of the back of the grill pan, and the temperature controller is located around the heating element.

[0005] The grill provided in this application has a temperature controller located around the heating element, which lowers the ambient temperature of the temperature controller. As a result, the insulation base of the temperature controller can be made of a material with relatively low temperature resistance but lower price, thereby saving costs and extending the service life of the temperature controller.

[0006] In one embodiment, the device further includes a housing, with the baking tray disposed inside the housing, the heating element and the temperature controller both disposed between the baking tray and the housing, the housing including a hinge mounting area, and the temperature controller disposed near the hinge mounting area.

[0007] In this embodiment, by placing the thermostat close to the hinge mounting area, the wires that the thermostat needs to connect to can be made shorter, resulting in a more compact structure and reduced wire material costs.

[0008] In one embodiment, the housing has an electrified area, and the area outside the electrified area of ​​the housing is a non-electrified area. The heating element includes a heating tube and a terminal block located at the end of the heating tube. The terminal block and the temperature controller are both located in the electrified area. The wall thickness of the electrified area of ​​the housing is greater than the wall thickness of the non-electrified area of ​​the housing.

[0009] Thus, by dividing the casing into sections, the walls of the electrified areas are made thicker, resulting in higher structural strength and resistance to strong external impacts, meeting the safety requirements of electronic components such as the heating element and temperature controller. The non-electrified areas, which do not require compliance with these safety regulations, are made thinner, saving material. The wiring terminals and temperature controller are both located in the electrified areas, resulting in a very compact structure that ensures the electrical safety of both. Therefore, this embodiment, while meeting the overall safety requirements of the grill, significantly saves material and reduces costs.

[0010] In one embodiment, the wiring terminals and the temperature controller are offset circumferentially from each other on the baking tray.

[0011] In this way, the wires connected to the terminals and the wires connected to the thermostat are less likely to interfere with each other, allowing the wires to be neatly arranged and threaded into the hinge.

[0012] In one embodiment, the housing further includes a baffle rib, which surrounds the charged area to form a capacitive cavity, thereby isolating the charged area from the non-charged area. The wiring terminal and the temperature controller are both located within the capacitive cavity.

[0013] By installing baffles to separate live and non-live areas, even if the non-live area is damaged, the baffles can still provide protection, preventing people from touching the terminals or thermostats and causing safety hazards. Therefore, installing baffles further enhances the safety protection performance of the live area.

[0014] In one embodiment, the baffle is provided with a connecting post for connecting to the baking pan.

[0015] In this embodiment, by setting a connecting post on the baffle, that is, the connecting post is part of the baffle, it can be seen that the connecting post serves as both a structure for connecting the baking pan and a structure for separating the charged and non-charged areas, which can further save the material used in the shell and thus further reduce the cost.

[0016] In one embodiment, a boss is provided on the back of the baking pan, and the temperature measuring part of the temperature controller is attached to the boss.

[0017] Adding a boss is equivalent to locally thickening the baking pan. In this way, the boss can transfer more heat from the heating element to the thermostat, so the temperature of the boss detected by the thermostat changes synchronously with the temperature of the heating element. Thus, the thermostat can control the temperature change of the heating element in a timely and effective manner.

[0018] In one embodiment, the baking pan has mounting holes on its back, and the temperature controller is mounted to the mounting holes by fasteners.

[0019] In this way, the thermostat is easy to install. By adjusting the fasteners, the temperature measuring part of the thermostat can be made to fit tightly against the boss, thereby ensuring the accuracy of temperature detection.

[0020] In one embodiment, the insulating base of the thermostat is made of bakelite.

[0021] In this way, bakelite material is inexpensive, which can save on production costs.

[0022] In one embodiment, the grill includes an upper grilling pan assembly and a lower grilling pan assembly. The upper grilling pan assembly is rotatably connected to the lower grilling pan assembly via a hinge. Both the upper grilling pan assembly and the lower grilling pan assembly include the grilling pan, the heating element, and the temperature controller.

[0023] Thus, the grill can achieve double-sided grilling. The thermostats in the upper and lower grill pan assemblies are both located around the heating element, which lowers the ambient temperature of the thermostat. As a result, the insulation base of the thermostat can be made of a material with relatively low temperature resistance but lower price, thereby saving costs and extending the service life of the thermostat.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figures 1 to 6 This application provides a grill, including a grill pan 20, a heating element 30, and a thermostat 40. Both the heating element 30 and the thermostat 40 are located on the back side of the grill pan 20, with the thermostat 40 positioned around the heating element 30. It is understood that the side of the grill pan 20 used for cooking is the front, and the side facing the housing 11 is the back. The thermostat 40, located on the back of the grill pan 20, detects the temperature of the heating element 30, thereby controlling its operating state. In this application, because the thermostat 40 is located around the heating element 30, the ambient temperature of the thermostat 40 is lowered. Therefore, the insulating base of the thermostat 40 can be made of a material with relatively low temperature resistance but lower cost, such as bakelite, thus saving costs and extending the service life of the thermostat 40.

[0038] It should be noted that for a grill with a double-sided grilling function, the grill pan 20 can be either the upper grill pan or the lower grill pan. In the embodiment shown in the attached figure, only the back of the lower grill pan has a temperature controller 40, but this is not a limitation. In other embodiments, only the back of the upper grill pan may have a temperature controller, or both the back of the upper and lower grill pans may have temperature controllers.

[0039] It is understood that this application does not improve the specific structure of the thermostat 40. The thermostats in the prior art can all be applied to this application, and the specific structure of the thermostat 40 will not be described in detail here.

[0040] In one embodiment, the insulating base of the thermostat 40 is made of bakelite, which is inexpensive and can save on production costs.

[0041] Furthermore, the grill also includes a housing 11, with the grill pan 20 disposed inside the housing 11. The heating element 30 and the temperature controller 40 are both located between the grill pan 20 and the housing 11. The housing 11 includes a hinge mounting area 113, with the temperature controller 40 positioned close to the hinge mounting area 113. In a grill with a hinge 50 connecting the upper grill pan assembly 100 and the lower grill pan assembly 200, an electrical conductor (e.g., a wire) is typically installed inside the hinge 50 to enable electrical communication between the electronic components of the upper grill pan assembly 100 and the lower grill pan assembly 200. For safety and aesthetic purposes, the electrical conductor is located inside the hinge 50. In this embodiment, by positioning the temperature controller 40 close to the hinge mounting area 113, the wire can extend from inside the hinge 50 and connect directly to the temperature controller 40. This means the wire connecting the temperature controller 40 can be shorter, resulting in a more compact structure and reduced wire material costs.

[0042] Furthermore, the housing 11 has a charged area 111, and the area outside the charged area 111 is a non-charged area 112. The heating element 30 includes a heating tube 31 and a terminal block 32 located at the end of the heating tube 31. The terminal block 32 and the temperature controller 40 are both located in the charged area 111. The wall thickness A of the charged area 111 of the housing 11 is greater than the wall thickness B of the non-charged area 112 of the housing 11. In this way, by dividing the housing 11 into sections, the wall thickness of the charged area 111 is made thicker, resulting in higher structural strength and the ability to withstand stronger external impacts, thus meeting the safety requirements of electronic components such as the heating element 30 and the temperature controller 40. The non-charged area 112 does not need to meet the corresponding safety requirements, and by making the wall thickness of the non-charged area 112 thinner, materials can be saved. Both the terminal block 32 and the thermostat 40 are located in the energized area 111, resulting in a very compact structure that ensures the electrical safety of both the terminal block 32 and the thermostat 40. Therefore, the above-mentioned arrangement in this embodiment, while meeting the overall safety requirements of the grill, significantly saves materials and reduces costs.

[0043] As mentioned earlier, the thermostat 40 is located near the hinge mounting area 113, and also in the energized area 111, meaning the energized area 111 is located near the hinge mounting area 113. Because both the terminal block 32 and the thermostat 40 are located in the energized area 111, the wires required to connect the terminal block 32 and the thermostat 40 can be made shorter, thus reducing wire material costs. Simultaneously, the energized area 111 can be made smaller, further saving material on the housing 11 and thus further reducing costs.

[0044] Furthermore, such as Figure 1As shown, the terminal block 32 and the thermostat 40 are staggered around the circumference of the baking pan 20. This makes it less likely for the wires connected to the terminal block 32 and the thermostat 40 to interfere with each other, allowing the wires to be neatly arranged and threaded into the hinge 50.

[0045] Further, please see Figures 1 to 6 The housing 11 also includes a baffle 12, which surrounds the energized area 111 to form a capacitive cavity 121. This baffle 12 isolates the energized area 111 from the non-energized area 112. The wiring terminal 32 and the temperature controller 40 are both located within the capacitive cavity 121. By separating the energized area 111 from the non-energized area 112 with the baffle 12, even if the non-energized area 112 is damaged, the baffle 12 can still provide protection, preventing people from touching the wiring terminal 32 or the temperature controller 40 and causing safety hazards. Therefore, the baffle 12 further enhances the safety protection performance of the energized area 111.

[0046] The baking tray 20 and the housing 11 are fixedly connected by fasteners (e.g., screws). Specifically, the housing 11 is provided with a connecting post 13 for connecting to the baking tray 20, such as... Figure 1 and Figure 2 As shown, the baffle 12 is also provided with a connecting post 13 for connecting to the baking tray 20. During installation, screws are inserted through the baking tray 20 and connected to the connecting post 13, thereby achieving a fixed connection between the baking tray 20 and the housing 11. The connecting post 13 has a threaded hole for easy screw connection. In this embodiment, by providing a connecting post 13 on the baffle 12, that is, the connecting post 13 is part of the baffle 12, it can be seen that the connecting post 13 serves both as a structure for connecting the baking tray 20 and as a structure for separating the charged area 111 and the non-charged area 112, which can further save material for the housing 11, thereby further reducing costs. Figure 1 As shown, in one embodiment, the baffle 12 is provided with one connecting post 13, and the housing 11 is also provided with three connecting posts 13 outside the baffle 12. Figure 2 As shown, in another embodiment, the baffle 12 is provided with two connecting posts 13, and the housing 11 is also provided with two connecting posts 13 outside the baffle 12. This application does not limit the number of connecting posts 13 provided on the baffle 12.

[0047] Furthermore, the portion of the heating tube 31 furthest from the terminal 32 is located in the non-energized area 112, while the portion of the heating tube 31 closest to the terminal 32 extends into the capacitor cavity 121. A clearance groove 122 is provided on the baffle 12 corresponding to the heating tube 31, and the heating tube 31 passes through the clearance groove 122. Thus, by providing the clearance groove 122, interference between the heating tube 31 and the baffle 12 can be avoided, ensuring that the main body of the heating tube 31 is located in the non-energized area 112. Simultaneously, the portion of the heating tube 31 closest to the terminal 32 and the terminal 32 are both located in the non-energized area 112, thereby ensuring the safe use of the heating element 30.

[0048] In this embodiment, there is a gap between the baffle 12 and the heating tube 31, that is, the baffle 12 and the heating tube 31 do not contact each other. In this way, the heating tube 31 will not directly transfer heat to the baffle 12, thereby reducing the temperature rise of the shell 11 and preventing the shell 11 from burning people.

[0049] Furthermore, a boss 21 is provided on the back of the baking pan 20, and the temperature measuring part of the temperature controller 40 is attached to the boss 21. Protruding the boss 21 is equivalent to locally thickening the baking pan 20; that is, the thickness of the baking pan 20 at the boss 21 is greater than the thickness of the baking pan 20 at other locations. In this way, the boss 21 can transfer more heat from the heating element 30 to the temperature controller 40, so that the temperature of the boss 21 detected by the temperature controller 40 changes synchronously with the temperature of the heating element 30, thus enabling the temperature controller 40 to control the temperature change of the heating element 30 in a timely and effective manner.

[0050] Furthermore, the baking pan 20 has mounting holes 22 on its back, and the temperature controller 40 is mounted to the mounting holes 22 by fasteners. In this way, the temperature controller 40 is easy to install, and by adjusting the fasteners, it can be ensured that the temperature measuring part of the temperature controller 40 is in close contact with the boss 21, thereby ensuring the accuracy of temperature detection.

[0051] Please see Figures 1 to 6 The grill provided in this application is a double-sided grilling grill, comprising an upper grilling plate assembly 100 and a lower grilling plate assembly 200. The upper grilling plate assembly 100 is rotatably connected to the lower grilling plate assembly 200 via a hinge 50. Both the upper grilling plate assembly 100 and the lower grilling plate assembly 200 include a grilling plate 20, a heating element 30, a thermostat 40, and a housing 11. Thus, the thermostat 40 in both the upper grilling plate assembly 100 and the lower grilling plate assembly 200 is located around the heating element 30, lowering the operating temperature of the thermostat 40. This allows the insulation base of the thermostat 40 to be made of a relatively inexpensive material with lower temperature resistance, such as bakelite, thereby saving costs and extending the service life of the thermostat 40.

[0052] Of course, in other embodiments, the grill may also be a single-sided grill.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
