Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking utensils, in particular to a shell of a grilling oven and the grilling oven. BACKGROUND

[0002] The shell of the grilling oven is usually made of bakelite powder by injection molding and hot pressing. In order to meet the safety regulations of the electronic components in the grilling oven, the wall thickness of the shell is usually thick, which greatly increases the production cost of the grilling oven. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a shell of a grilling oven which can meet the safety regulations of electronic components and reduce the cost.

[0004] The present application provides a shell of a grilling oven, which is provided with a live area for accommodating the wiring terminals of electronic components, and a non-live area outside the live area of the shell, wherein the wall thickness of the live area of the shell is greater than that of the non-live area of the shell.

[0005] The shell of the grilling oven of the present application is divided into different areas, so that the wall thickness of the live area is thick and has high structural strength, which can resist strong external impact to meet the safety regulations of electronic components, while the non-live area does not need to meet the corresponding safety regulations, so that the wall thickness of the non-live area can be made thinner, thereby greatly saving materials and reducing costs while meeting the safe use of the grilling oven.

[0006] In one embodiment, a stop rib is further included, which is arranged around the live area to form a live cavity, so that the live area and the non-live area are isolated, and the wiring terminals of the electronic components are accommodated in the live cavity.

[0007] In this way, the live area and the non-live area are separated by the stop rib, so that even if the non-live area is damaged, the stop rib can play a protective role to avoid the risk of touching the wiring terminals of the electronic components. It can be seen that the safety protection performance of the live area is further improved by setting the stop rib.

[0008] In one embodiment, the wall thickness of the live area of the shell is 2mm-5mm, and the wall thickness of the non-live area of the shell is 1.5mm-3mm.

[0009] In this way, the shell can meet the safety regulations of the electronic components installed inside, and the thickness of the non-live area is thin, thereby reducing the production cost.

[0010] In one embodiment, the wall thickness of the live area of the shell is 2.5mm-4mm, and the wall thickness of the non-live area of the shell is 1.8mm-2.5mm.

[0011] Thus, the shell can better meet the safety requirements of the electronic components installed inside and the demand of reducing production cost.

[0012] In one embodiment, the proportion of the area of the outer surface of the live area to the total outer surface area of the shell is 3% to 50%.

[0013] Thus, in the case of meeting the installation space of the terminal, the proportion of the live area is small, and the range of the area with thick shell thickness is small, thereby greatly reducing the production cost.

[0014] In one embodiment, the proportion of the area of the outer surface of the live area to the total outer surface area of the shell is 5% to 20%.

[0015] Thus, the size of the live area can better meet the installation space demand of the terminal, and the range of the area with thick shell thickness is small, thereby greatly reducing the production cost.

[0016] In one embodiment, the shell further comprises a hinge mounting area, and the live area is arranged close to the hinge mounting area.

[0017] In a grilling machine provided with a hinge and connecting the upper baking tray assembly and the lower baking tray assembly through the hinge, an electrically conductive part is usually arranged inside the hinge to realize the electrical connection of the electronic components of the upper baking tray assembly and the electronic components of the lower baking tray assembly. In order to meet the safety use demand and the appearance demand, the electrically conductive part is arranged inside the hinge. The embodiment arranges the live area close to the hinge mounting area, so that the electrically conductive part can directly enter the electrical connection terminal of the electronic components after extending out of the hinge, thereby the electrically conductive part can be arranged shorter, thereby saving the amount of the electrically conductive part. At the same time, the live area can also be arranged smaller, thereby the amount of the material of the shell in the live area and the amount of the material of the blocking rib can be reduced, thereby further reducing the cost.

[0018] The application also provides a grilling machine, comprising a baking tray, electronic components and the above-mentioned shell, the baking tray is arranged inside the shell, the electronic components comprise a heating part, the heating part is arranged between the baking tray and the shell, the heating part comprises a heating pipe body and a terminal arranged at the end of the heating pipe body, and the terminal is arranged inside the live area.

[0019] The cooking and roasting machine is divided into a plurality of zones by the shell, and the terminal of the heating element is arranged in the live zone, so that the wall thickness of the live zone is made thicker, the structural strength is higher, and the live zone can resist stronger external impact to meet the safety requirements of the electronic components, while the non-live zone does not need to meet the corresponding safety requirements, so that the wall thickness of the non-live zone can be made thinner, thereby greatly saving the material and reducing the cost under the condition of meeting the safe use of the cooking and roasting machine.

[0020] In one of the embodiments, the shell further comprises a blocking rib, the blocking rib is arranged around the live zone to form a live cavity, so that the live zone and the non-live zone are isolated, the part of the heating pipe body away from the terminal is arranged in the non-live zone, the part of the heating pipe body close to the terminal extends into the live cavity, the blocking rib is provided with a avoiding slot corresponding to the heating pipe body, and the heating pipe body is arranged in the avoiding slot.

[0021] In this way, the avoiding slot is arranged to avoid the interference between the heating pipe body and the blocking rib, and ensure that the main part of the heating pipe body is arranged in the non-live zone, and the part of the heating pipe body close to the terminal and the terminal are arranged in the non-live zone, so as to ensure the safe use of the heating element.

[0022] In one of the embodiments, the blocking rib is provided with a connecting column, and the connecting column is used to connect with the baking tray.

[0023] In this embodiment, the connecting column is arranged on the blocking rib, that is, the connecting column is part of the blocking rib, so that the connecting column serves as a structure for connecting the baking tray and a structure for separating the live zone and the non-live zone, and the material of the shell can be further saved, thereby further reducing the cost.

[0024] In one of the embodiments, the electronic components further comprise a temperature controller arranged on the back of the baking tray, and the temperature controller is arranged in the live zone of the shell.

[0025] In this way, the live zone with a thicker wall thickness effectively ensures the electrical safety of the temperature controller. Moreover, the temperature controller and the terminal of the heating element are arranged in the live zone, and the structure is more compact.

[0026] In one of the embodiments, the back of the baking tray is provided with a boss, and the temperature measuring part of the temperature controller is attached to the boss.

[0027] The boss is equivalent to locally thickening the baking tray, so that the boss can transmit more heat of the heating element to the temperature controller, so that the temperature of the boss detected by the temperature controller and the temperature of the heating element change synchronously, and the temperature controller can timely and effectively control the temperature change of the heating element.

[0028] In one of the embodiments, the heating pipe body is annular, and the two ends of the heating pipe body are overlapped along the circumference of the baking tray.

[0029] In this way, the heating pipe body forms a complete ring along the circumference of the baking tray, that is, there is no gap, so that the heating of the circumference of the baking tray is more uniform, thereby improving the cooking effect of the food.

[0030] In one of the embodiments, the length of the overlapped part of the two ends of the heating pipe body is L1, and L1 is 5mm-50mm.

[0031] In this way, the integrity of the heating pipe body along the circumference of the baking tray is effectively ensured, and the length of the heating pipe body is relatively long, so that more heat can be emitted in a limited space, thereby improving the efficiency of cooking food.

[0032] In one of the embodiments, the distance between the overlapped parts of the two ends of the heating pipe body is L2, and L2 is 5mm-35mm.

[0033] In this way, the two ends of the heating pipe body are not too close to affect the connection of the terminal and the wire, nor too far apart to occupy a large space.

[0034] In one of the embodiments, the shell further comprises a hinge mounting area, and the terminal is arranged away from one end of the heating pipe body and towards the hinge mounting area, and the included angle between the terminal and the horizontal plane is θ, and θ is 15°-45°.

[0035] In this way, sufficient space between the terminal and the heating pipe body can be ensured, so that a heat insulation structure is not required, and at the same time, the terminal is close to the hinge, so that the wire can be arranged to be relatively short, thereby saving costs.

[0036] In one of the embodiments, the grilling machine comprises an upper baking tray assembly and a lower baking tray assembly, the upper baking tray assembly is rotatably connected to the lower baking tray assembly by a hinge, and the upper baking tray assembly and the lower baking tray assembly each comprise the shell and the baking tray.

[0037] In this way, the grilling machine can realize double-sided grilling, and by arranging the upper baking tray assembly and the lower baking tray assembly to each comprise the shell and the baking tray, the material usage of the shell can be greatly reduced under the condition of meeting the safety requirements of electronic components, thereby saving costs.

In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0048] ​​It is to be understood that when a component is referred to as being "on" or "connected to" another component, it can be directly on or connected to the other component or intervening components can be present.

[0049] In addition, the terms "first", "second", etc. are used herein only to describe various conditions, and are not intended to denote relative importance or a quantity of the indicated conditions. Thus, a feature defined with "first" or "second" can include at least one of the feature, explicitly or implicitly. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0050] In the present application, unless otherwise explicitly specified and limited, "on", "under", "above", and "over" of a first feature to a second feature can mean that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium.

"Below", "under", and "underneath" of a first feature to a second feature can mean that the first feature is directly below or obliquely below the second feature, or only means that the first feature is horizontally lower than the second feature.

[0051] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. The use of the terms "and / or" in the description of the present application includes a set of one or more associated listed items.

[0052] See Figures 1 to 4The application provides a shell 11 of a grill, the shell 11 is provided with an electrified area 111 for accommodating a wiring terminal of an electronic component, an area outside the electrified area 111 of the shell 11 is a non-electrified area 112, and the wall thickness A of the electrified area 111 of the shell 11 is greater than the wall thickness B of the non-electrified area 112 of the shell 11. In this way, by partitioning the shell 11, the wall thickness of the electrified area 111 is made thicker, the structural strength is higher, and stronger external impact can be resisted to meet the safety requirements of the electronic component, while the non-electrified area 112 does not need to meet the corresponding safety requirements, so that the wall thickness of the non-electrified area 112 can be made thinner, thereby greatly saving materials and reducing costs under the condition of meeting the safe use of the whole grill.

[0053] Further, the wall thickness A of the electrified area 111 of the shell 11 is 2-5 mm, and the wall thickness B of the non-electrified area 112 of the shell 11 is 1.5-3 mm. In this way, the shell 11 can meet the safety requirements of the electronic component installed inside, and the non-electrified area 112 is thinner, thereby reducing the production cost. Illustratively, the wall thickness A of the electrified area 111 of the shell 11 can be 2 mm, 3 mm, 4 mm, 5 mm, or any other value within the range of 2-5 mm. The wall thickness B of the non-electrified area 112 of the shell 11 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, or any other value within the range of 1.5-3 mm. Preferably, the wall thickness A of the electrified area 111 of the shell 11 is 2.5-4 mm, and the wall thickness B of the non-electrified area 112 of the shell 11 is 1.8-2.5 mm, so that the shell 11 can better meet the safety requirements of the electronic component installed inside and the demand for reducing the production cost.

[0054] Further, the proportion of the area S1 of the outer surface of the electrified area 111 to the total outer surface area S2 of the shell 11 is 3% to 50%. It can be understood that the "outer surface area" refers to the area of the surface on the outward side of the shell 11. The smaller S1 / S2 is, the smaller the proportion of the electrified area 111 is, and thus the lower the cost is. In the embodiment, S1 / S2 = 3% to 50%. In the case of meeting the installation space of the wiring terminal, the proportion of the electrified area 111 is small, the range of the area of the shell 11 with a relatively large thickness is small, and thus the production cost is greatly reduced. Illustratively, the proportion of the area S1 of the outer surface of the electrified area 111 to the total outer surface area S2 of the shell 11 can be 3%, 5%, 8%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or any other value within the range of 3% to 50%. Preferably, the proportion of the area S1 of the outer surface of the electrified area 111 to the total outer surface area S2 of the shell 11 is 5% to 20%. In this way, the size of the electrified area 111 can be better considered to meet the installation space requirement of the wiring terminal, and the range of the area of the shell 11 with a relatively large thickness is small, and thus the production cost can be greatly reduced.

[0055] Further, the shell 11 further comprises a blocking rib 12, which is arranged around the electrified area 111 to form an electrified cavity 121. The blocking rib 12 separates the electrified area 111 and the non-electrified area 112, and the wiring terminal of the electronic component is accommodated in the electrified cavity 121. In this way, the blocking rib 12 separates the electrified area 111 and the non-electrified area 112, and even if the non-electrified area 112 is damaged, the blocking rib 12 can play a protective role to avoid the safety hazard caused by touching the wiring terminal of the electronic component. It can be seen that the safety protection performance of the electrified area 111 is further improved by arranging the blocking rib 12.

[0056] Further, the blocking rib 12 is in a constricted shape from one end to the other end of the shell 11. In this way, compared with the case where the thickness of the blocking rib is constant, the thickness of the blocking rib 12 in the embodiment changes in a decreasing manner, which can further reduce the amount of material, thereby saving cost, and also facilitate the molding and demolding of the shell 11.

[0057] Further, the shell 11 further comprises a hinge mounting area 113, and the electrified area 111 is arranged close to the hinge mounting area 113. In the griddle oven provided with the hinge 50 and connected with the upper baking tray assembly 100 and the lower baking tray assembly 200 through the hinge 50, the inside of the hinge 50 is usually provided with an electrically conductive member (such as an electric wire) to realize the electrical connection between the electronic components of the upper baking tray assembly 100 and the electronic components of the lower baking tray assembly 200. In order to meet the requirements of safe use and the requirements of appearance, the electrically conductive member is arranged in the inside of the hinge 50. In the embodiment, the electrified area 111 is arranged close to the hinge mounting area 113, so that the electrically conductive member can directly enter the connection of the electrified area 111 and the terminal of the electronic components after extending out of the inside of the hinge 50, and thus the electrically conductive member can be arranged to be shorter, thereby saving the amount of the electrically conductive member. At the same time, the electrified area 111 can also be arranged to be smaller, so that the amount of the material of the shell 11 in the electrified area 111 and the amount of the material of the blocking rib 12 can be reduced, thereby further reducing the cost.

[0058] Please refer to Figures 1 to 7 The application further provides a griddle oven, which comprises a baking tray 20, electronic components and the shell 11 described above. The baking tray 20 is arranged inside the shell 11, and the electronic components comprise a heating member 30, the heating member 30 is arranged between the baking tray 20 and the shell 11, and the heating member 30 comprises a heating pipe body 31 and a terminal 32 arranged at the end of the heating pipe body 31, and the terminal 32 is arranged inside the electrified area 111. It can be understood that the heating pipe body 31 is the heating part of the heating member 30, and the terminal 32 is used to connect with the electric wire to realize the electrical conduction of the heating pipe body 31, so that the heating pipe body 31 generates heat when starting, and then heats the baking tray 20. The griddle oven divides the shell 11 into different areas, and arranges the terminal 32 of the heating member 30 inside the electrified area 111, so that the wall thickness of the electrified area 111 is made thicker, the structural strength is higher, and the external impact can be resisted, so as to meet the safety requirements of the electronic components, and the non-electrified area 112 does not need to meet the corresponding safety requirements, so that the wall thickness of the non-electrified area 112 can be made thinner, thereby greatly saving the material and reducing the cost under the condition of meeting the safe use of the griddle oven.

[0059] Further, the part of the heating pipe body 31 away from the terminal 32 is arranged in the non-electrified area 112, the part of the heating pipe body 31 close to the terminal 32 extends into the electrified cavity 121, the blocking rib 12 is provided with a avoiding slot 122 corresponding to the heating pipe body 31, and the heating pipe body 31 is arranged in the avoiding slot 122. In this way, the avoiding slot 122 is arranged to avoid the interference between the heating pipe body 31 and the blocking rib 12, so as to ensure that the main part of the heating pipe body 31 is arranged in the non-electrified area 112, and the part of the heating pipe body 31 close to the terminal 32 and the terminal 32 are arranged in the non-electrified area 112, thereby ensuring the safe use of the heating member 30.

[0060] In this embodiment, there is a gap between the ribs 12 and the heating tube body 31, that is, the ribs 12 and the heating tube body 31 are not in contact. In this way, the heating tube body 31 will not directly transfer heat to the ribs 12, thereby reducing the temperature rise of the shell 11 and preventing people from being burned by the shell 11.

[0061] The baking tray 20 and the housing 11 are fixedly connected by fasteners (such as screws). Specifically, a connecting post 13 is provided on the housing 11, and the connecting post 13 is used to connect with the baking tray 20. Figure 1 and Figure 2 As shown, the retaining rib 12 is also provided with a connecting post 13 for connecting to the baking tray 20. During installation, screws are passed through the baking tray 20 and connected to the connecting post 13, thereby achieving a fixed connection between the baking tray 20 and the shell 11. A threaded hole is provided in the connecting post 13 to facilitate the connection of the screw therewith. In this embodiment, by providing the connecting post 13 on the retaining rib 12, that is, the connecting post 13 serves as a part of the retaining rib 12, it can be seen that the connecting post 13 serves as a structure for connecting the baking tray 20 and also as a structure for separating the charged area 111 and the non-charged area 112, which can further save the material used for the shell 11, thereby further reducing the cost. As shown Figure 1 As shown in FIG. 1 , in one embodiment, a connecting column 13 is provided on the retaining rib 12, and three connecting columns 13 are further provided on the housing 11 outside the retaining rib 12. Figure 2 As shown, in another embodiment, two connecting posts 13 are provided on the retaining rib 12, and two connecting posts 13 are further provided on the housing 11 outside the retaining rib 12. The present application does not limit the number of connecting posts 13 provided on the retaining rib 12.

[0062] Further, if Figure 3 and Figure 6 As shown, the electronic components further include a thermostat 40 disposed on the back of the baking tray 20. It is understood that the side of the baking tray 20 used for cooking is the front side, and the side facing the housing 11 is the back side. The thermostat 40 is disposed on the back side of the baking tray 20 and is used to detect the temperature of the heating element 30, thereby controlling the operating state of the heating element 30.

[0063] In one embodiment, the thermostat 40 is located in the charged area 111 of the housing 11. In this way, the thicker wall of the charged area 111 effectively ensures the electrical safety of the thermostat 40. In addition, the connection terminals 32 of the thermostat 40 and the heating element 30 are both located in the charged area 111, making the structure more compact. Figure 3 In one embodiment, the charged area 111 is located near the hinge installation area 113. In this embodiment, since the thermostat 40 corresponds to the charged area 111 of the housing 11, the thermostat 40 is located near the hinge installation area 113. In this way, the wires required to connect the thermostat 40 can be set shorter, making the structure more compact and reducing the cost of wire materials. It should be noted that Figure 3 andFigure 6 In the illustrated embodiment, the temperature controller 40 is arranged on the back of the lower baking tray 20, but is not limited thereto. In other embodiments, the temperature controller 40 can be arranged on the back of the upper baking tray, or the temperature controller 40 can be arranged on the back of both the upper baking tray and the lower baking tray.

[0064] Further, the temperature controller 40 is arranged on the periphery of the heating element 30. In the prior art, the temperature controller is usually arranged on the inner side of the heating element. The temperature controller is used in a high-temperature environment, and the insulating seat of the temperature controller is usually made of ceramic material, which has a high cost. Moreover, the service life of the temperature controller is short due to the long-term high-temperature environment. In the present embodiment, the temperature controller 40 is arranged on the periphery of the heating element 30, so that the temperature of the environment in which the temperature controller 40 is used is reduced. Therefore, the insulating seat of the temperature controller 40 can be made of a material with relatively low temperature resistance but low price, such as bakelite, thereby saving costs and prolonging the service life of the temperature controller 40.

[0065] It is worth mentioning that the specific structure of the temperature controller 40 is not improved in the present application. The temperature controller in the prior art can be applied to the present application, and the specific structure of the temperature controller 40 is not described herein.

[0066] Further, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 . The back of the baking tray 20 is provided with a boss 21, and the temperature measuring part of the temperature controller 40 is attached to the boss 21. The boss 21 is equivalent to locally thickening the baking tray 20, that is, the thickness of the baking tray 20 at the boss 21 is greater than the thickness of the baking tray 20 at other positions. 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, and the temperature controller 40 can timely and effectively control the temperature change of the heating element 30.

[0067] Further, the back of the baking tray 20 is provided with a mounting hole 22, and the temperature controller 40 is mounted in the mounting hole 22 by a fastener. In this way, the temperature controller 40 is easy to install, and the fastener can be adjusted to ensure that the temperature measuring part of the temperature controller 40 is tightly attached to the boss 21, thereby ensuring the accuracy of temperature detection.

[0068] Please refer to Figure 7 . The heating pipe body 31 is annular, and the two ends of the heating pipe body 31 overlap along the circumference of the baking tray 20. In this way, the heating pipe body 31 forms a complete ring along the circumference of the baking tray 20, that is, there is no gap, so that the heating of the circumference of the baking tray 20 is more uniform, thereby improving the cooking effect of the food.

[0069] In the embodiment, the heating pipe body 31 is in a circular ring shape, but is not limited thereto, and in other embodiments, the heating pipe body 31 can also be in a square ring shape, an oval ring shape, a snake ring shape, a butterfly ring shape, or a special-shaped ring shape, and the present application does not limit this, as long as there is an overlapping portion at both ends of the heating pipe body 31 to form a complete ring in the circumferential direction of the baking tray 20.

[0070] Further, the length of the overlapping portion at both ends of the heating pipe body 31 is L1, and L1 is 5mm-50mm. In this way, the integrity of the heating pipe body 31 in the circumferential direction of the baking tray 20 is effectively ensured, and at the same time, the heating pipe body 31 is relatively long, and can emit more heat in a limited space, thereby facilitating the improvement of the efficiency of cooking food. Specifically, L1 can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, or any other value within the range of 5mm-50mm. Preferably, L1 is 10mm-30mm.

[0071] Further, the distance between the overlapping portions at both ends of the heating pipe body 31 is L2, and L2 is 5mm-35mm. In this way, the two ends of the heating pipe body 31 will not be too close to affect the connection of the terminal 32 and the wire, nor will they be too far apart to occupy a large space. Specifically, L2 can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, or any other value within the range of 5mm-35mm. Preferably, L2 is 10mm-20mm.

[0072] Please refer to Figure 3 , the end of the terminal 32 away from the heating pipe body 31 is arranged towards the hinge mounting area 113. The terminal 32 is arranged at an acute angle with the horizontal plane. In this way, the wire connected to the terminal 32 can be arranged to be relatively short, thereby saving the cost of the wire. At the same time, since the terminal 32 is arranged at an acute angle with the horizontal plane, that is, the terminal 32 is inclined towards the shell 11, even if there is an overlapping portion at both ends of the heating pipe body 31, there is a certain distance between the terminal 32 inside the heating pipe body 31 and the heating pipe body 31, so that the wire connected to the terminal 32 and the heating pipe body 31 do not need to be provided with a heat insulation structure, thereby avoiding the increase in cost caused by the setting of the heat insulation structure.

[0073] Further, the included angle between the terminal 32 and the horizontal plane is θ, and θ is 15°-45°. It is worth mentioning that if θ is too small, the distance between the terminal 32 and the heating pipe body 31 is small, and a heat insulation structure needs to be arranged; if θ is too large, the wire connected with the terminal 32 needs to be arranged to be relatively long, thereby increasing the cost. In the embodiment, θ is 15°-45°, which can ensure that there is enough spacing between the terminal 32 and the heating pipe body 31, so that the heat insulation structure does not need to be arranged, and at the same time, the terminal 32 is close to the hinge 50, so that the wire can be arranged to be relatively short, thereby saving the cost. Specifically, θ can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, or any other value within the range of 15°-45°. Preferably, θ is 20°-35°.
