Detailed Implementation
[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0034] See Figures 1-6This utility model discloses a heating element installation structure, including a mounting base 10, a heating element, and a temperature detection component, wherein the heating element and the temperature detection component can be installed on the mounting base 10.
[0035] The specific temperature detection assembly includes a temperature sensing element 31 and an elastic member 32. The temperature sensing element 31 has a sensing end and is mounted on the mounting base 10. After being installed on the mounting base 10, the sensing end of the temperature sensing element 31 faces the heating element. The elastic member 32 is mounted on the mounting base 10 and provides elastic stress. Under the action of this elastic stress, the temperature sensing element 31 can move closer to the heating element, so that the sensing end remains in contact with the heating element.
[0036] Based on the above structure, when using the heating element installation structure of this utility model, the heating element installation structure can be used on cooking structures such as air fryers, ovens, and steamers. During assembly, the heating element and temperature detection component are first installed on the mounting base 10, and then the mounting base 10 is assembled to the cooking body 40. That is, after the heating element and temperature detection component are assembled outside the cooking body 40, they are assembled to the cooking body 40 by screws, bolts, or clips. The heating element heats the cooking cavity 41 of the cooking body 40. After the mounting base 10 is assembled to the cooking body 40, the heating element corresponds to the heating position of the cooking cavity 41, which is convenient for assembly.
[0037] In this embodiment, since the temperature sensing element 31 on the mounting base 10 can be kept against the heating body under the action of the elastic member 32, if the heating body deforms and detaches from the end face of the mounting base 10, the elastic stress provided by the elastic member 32 can drive the sensing end of the temperature sensing element 31 to move closer to the heating body to adapt to the deformation of the heating body. If the heating body becomes loose due to screws or bolts, resulting in a gap with the end face of the mounting base 10, the elastic stress provided by the elastic member 32 can also drive the sensing end of the temperature sensing element 31 to extend towards the heating body and remain against it.
[0038] That is, the elastic stress of the elastic component 32 drives the temperature detection component 31 to always remain in a contact state, adapting to the deformation or loosening state of the heating element, so that the detection end of the temperature detection component 31 always remains in contact with the heating element, thus maintaining the accuracy of the detection results.
[0039] Furthermore, the aforementioned temperature detection assembly also includes a mounting housing 33, through which the temperature detection element 31 passes and connects. Thus, the mounting housing 33 covers the outer periphery of the temperature detection element 31, protecting it and reducing damage during assembly. It also allows for direct assembly between the mounting housing 33 and the mounting base 10, facilitating assembly. The detection end of the temperature detection element 31 can extend from the end of the mounting housing 33. Based on this structure, one end of the elastic member 32 abuts against the mounting housing 33, and the other end abuts against the mounting base 10. The elastic stress provided by the elastic member 32 drives the mounting housing 33 towards the heating element, ensuring a stable abutment state for the detection end extending from the mounting housing 33.
[0040] It should be noted that the temperature detection element 31 mentioned above can be a temperature sensor in the prior art.
[0041] Furthermore, a mounting groove 12 can be provided on the mounting base 10. When assembling the temperature detection element 31 with the mounting base 10, the mounting housing 33, which is fitted outside the temperature detection element 31, can be installed into the mounting groove 12 so that the mounting groove 12 can be used to position and assemble the stable detection element.
[0042] The aforementioned elastic component 32 is clamped between the mounting housing 33 and the bottom wall 122 of the mounting groove. The top of the side wall of the mounting groove 12 is provided with a limiting component 121. The limiting component 121 is used to abut against the mounting housing 33 to prevent the mounting housing 33 from separating from the mounting groove 12.
[0043] In this embodiment, the limiting member 121 can be set at the top of the mounting groove 12, so that there is a certain movable gap between the limiting member 121 and the bottom wall 122 of the mounting groove. Since the elastic member 32 is clamped between the mounting housing 33 and the bottom wall 122 of the mounting groove, the elastic stress provided by the elastic member 32 will cause the mounting housing 33 to move upward and closer to the heating element. Therefore, the limiting member 121 is positioned above the mounting housing 33 to limit the movement and prevent detachment.
[0044] In addition, the movable gap between the limiting member 121 and the bottom wall 122 of the mounting groove allows the mounting housing 33 to float, adapting to the deformation of the heating element.
[0045] Furthermore, a protruding step 331 can be provided around the periphery of the mounting housing 33. The aforementioned elastic member 32 is clamped between the protruding step 331 and the bottom wall 122 of the mounting groove. Based on this structure, the limiting member 121 can abut against the protruding step 331 to prevent the mounting housing 33 from separating from the mounting groove 12. That is, when the mounting housing 33 is assembled into the mounting groove 12, the protruding step 331 of the mounting housing 33 can float between the limiting member 121 and the bottom wall 122 of the mounting groove, while the temperature sensing member 31 is inserted in the middle position of the mounting housing 33 and will not be affected by the limiting member 121.
[0046] Furthermore, the elastic component 32 is an annular elastic sheet, which is fitted around the outer periphery of the temperature sensing element 31 and clamped between the protruding step 331 and the bottom wall 122 of the mounting groove. In this way, the annular elastic sheet can provide a balanced elastic stress in the circumferential direction of the mounting housing 33. The mounting housing 33 can be driven by the circumferential elastic stress to stay close to the heating element, preventing the mounting housing 33 from swaying due to uneven elastic stress. Therefore, the sensing end of the temperature sensing element 31 can be kept in a contact state under balanced elastic stress, preventing the sensing accuracy from being affected by swaying.
[0047] Furthermore, in this embodiment, the heating element is a first heating thick film. The heating thick film is a structure of thick film heating material printed on an insulating body in the prior art. When energized, the thick film heating material can generate heat. The first heating thick film is installed on the end face of the mounting base 10 and attached to the detection end. The flat heating thick film heats the cooking cavity 41. In this way, the heating structure formed after the first heating thick film and the mounting base 10 are assembled is relatively thin. Compared with the heating element using heating tubes, electromagnetic heating groups and other structures, it has a smaller thickness. After being applied to the cooking device, the overall height of the cooking device is reduced.
[0048] Since the heating element uses a first heating thick film, the first heating thick film is prone to deformation during use. Under the action of the elastic component 32, the detection end of the temperature detection component 31 can always keep in close contact with the base and work on the surface of the first heating thick film. If the first heating thick film deforms due to heating, the deformation gap between the temperature detection component 31 and the deformed first heating thick film can be compensated by the elastic stress provided by the elastic component 32, thereby reducing the misjudgment of the temperature detection component 31 due to the deformation of the first heating thick film.
[0049] Furthermore, to facilitate the connection of the first heating film to electricity, an electrical terminal 11 can be provided on the mounting base 10. One end of the electrical terminal 11 is electrically connected to the first heating film, and the other end of the electrical terminal 11 is formed as a power receiving terminal. In this way, when wiring, the electrical terminal 11 can be directly connected to the wiring on the cooking body 40, which is convenient.
[0050] Furthermore, the mounting base 10 is equipped with two sets of temperature detection components, so that the two sets of temperature detection elements 31 can detect the temperature on both sides of the first heating film, thereby improving the accuracy of temperature detection.
[0051] Example 2,
[0052] See Figures 1-8 The cooking device shown includes a cooking body 40 and a heating element mounting structure of Embodiment 1. The cooking body 40 is provided with a cooking cavity 41, and the bottom wall of the cooking cavity 41 is provided with a heating port. The mounting base 10 is installed at the bottom of the cooking body 40. After the mounting base 10 is installed on the cooking body 40, the heating element on the mounting base 10 can be correspondingly covered to the heating port, so that the heating element can heat the cooking cavity 41.
[0053] During assembly, the heating element and temperature detection component are first installed onto the mounting base 10, and then the mounting base 10 is assembled onto the cooking body 40. That is, the heating element and temperature detection component are assembled outside the cooking body 40 and then assembled onto the cooking body 40 using screws, bolts, or clips. The heating element heats the cooking cavity 41 of the cooking body 40. After the mounting base 10 is assembled onto the cooking body 40, the heating element corresponds to the heating position of the cooking cavity 41, making assembly convenient.
[0054] In this embodiment, since the temperature sensing element 31 on the mounting base 10 can be kept against the heating body under the action of the elastic member 32, if the heating body deforms and detaches from the end face of the mounting base 10, the elastic stress provided by the elastic member 32 can drive the sensing end of the temperature sensing element 31 to move closer to the heating body to adapt to the deformation of the heating body. If the heating body becomes loose due to screws or bolts, resulting in a gap with the end face of the mounting base 10, the elastic stress provided by the elastic member 32 can also drive the sensing end of the temperature sensing element 31 to extend towards the heating body and remain against it.
[0055] That is, the elastic stress of the elastic component 32 drives the temperature detection component 31 to always remain in a contact state, adapting to the deformation or loosening state of the heating element, so that the detection end of the temperature detection component 31 always remains in contact with the heating element, thus maintaining the accuracy of the detection results.
[0056] It should be noted that the heating element in this embodiment can preferably be the first heating film mentioned above, which can effectively reduce the overall height of the cooking device.
[0057] More specifically, a heat insulation cover 42, a diversion fan 44, and a second heating film 43 may be provided at the top of the cooking cavity 41. The second heating film 43 is located below the heat insulation cover 42; the diversion fan 44 is located between the second heating film 43 and the heat insulation cover 42; and an air vent 431 is provided in the middle of the second heating film 43.
[0058] In this way, heating structures are provided at both the top and bottom of the cooking cavity 41 to heat the food inside the cavity evenly. Furthermore, since the upper heating structure is a second heating film 43, which works in conjunction with the lower first heating film, heating films are used at both the top and bottom of the cooking cavity 41. This reduces the increase in the height of the cooking unit 40 due to the thickness of the heating structures, thus lowering the overall height of the cooking device.
[0059] Furthermore, after the second heating film 43 is placed at the top of the cooking cavity 41, in order to increase the flow speed of hot air during the heating process, a diversion fan 44 is provided. The diversion fan 44 is driven by a motor located above the heat insulation cover 42. The diversion fan 44 can divert the heat generated by the second heating film 43 downward through the gap between the periphery of the second heating film 43 and the inner peripheral wall of the heat insulation cover 42, and at the same time, the heat is returned through the air outlet 431 in the middle of the second heating film 43. In this way, the heat generated by the second heating film 43 can circulate around the second heating film 43, thereby improving the heating efficiency.
[0060] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
