Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and more specifically, to a far-infrared electric oven. Background Technology

[0002] Barbecue is a method of cooking food directly over fire. It's the most primitive method, yet it best preserves the original flavor of the food, which is why it has always been popular. However, while this traditional method brings joy to people, the resulting fumes pollute the environment. In response to this, electric barbecue grills that use electricity to heat the food have been developed.

[0003] In existing electric barbecue grills, to prevent grease and seasonings from dripping directly onto the heating element inside the grill, the heat source is usually fixed to the inner wall of the grill. The working principle is to heat the gas inside the grill and then use the hot air from the top outlet of the grill to bake the food. In this type of electric barbecue grill, the heat source does not directly heat the food, resulting in low heat utilization and high energy loss. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a far-infrared electric oven is provided, which can improve the heat utilization rate of the heating plate and reduce power consumption.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a far-infrared electric oven, the improvement of which is that it includes a support frame, a heat preservation frame, a heating plate and a bottom sealing plate; The support frame is cubic in shape, and the insulation frame includes multiple insulation boards. The insulation frame is disposed inside the support frame, and the multiple insulation boards are sequentially fixedly installed at the side openings of the support frame. The bottom sealing plate is fixedly installed at the opening at the bottom of the support frame. The bottom sealing plate and multiple insulation plates enclose a heating cavity with an opening at the top. Two heating plates are symmetrically installed inside the heating cavity, and the angle between the heating plate and the plane where the opening of the heating cavity is located is an acute angle.

[0006] In the above structure, a fixing member is provided inside the heating chamber. One end of the fixing member is fixedly installed on the inner wall of the insulation plate, and the other end of the fixing member is bent and fixedly connected to the end of the heating plate.

[0007] In the above structure, the far-infrared electric oven also includes a corner sealing plate, which is symmetrically arranged at the corner of the opening of the heating cavity, so that a heating port is reserved at the top of the heating cavity.

[0008] In the above structure, a cover plate is slidably installed on the heating port of the heating chamber.

[0009] In the above structure, the far-infrared electric oven also includes multiple protective plates, which are fixedly installed on the outside of the insulation plate and the bottom sealing plate.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0021] Reference Figure 1 , Figure 2 As shown, this utility model discloses a far-infrared electric oven. Specifically, the far-infrared electric oven includes a support frame 10, a heat preservation frame 20, a heating plate 30, and a bottom sealing plate 40. The support frame 10 is cubic in shape; in this embodiment, it is rectangular, with a total of 12 profiles distributed along the X, Y, and Z directions. The shape and material can be selected according to actual needs. In this embodiment, the X-direction and Y-direction profiles are integrally die-cast and fixed to the Z-direction profiles by riveting. Since this structure is common in this technical field, it will not be described in detail in this embodiment. Figure 2 As shown, the insulation frame 20 includes multiple insulation boards 201. In this embodiment, the insulation frame 20 includes four insulation boards 201. The four insulation boards 201 are connected end to end in sequence to form a rectangular parallelepiped structure that runs vertically through the frame. The insulation frame 20 is disposed inside the support frame 10, and each insulation board 201 is fixed in sequence at an opening on the side of the support frame 10. The material of the insulation board 201 can be selected according to actual needs, which is common knowledge in the art and will not be described in detail in this specification. In addition, a pad 101 is provided at the bottom of the support frame 10, and multiple support feet 102 are provided at the bottom of the pad 101.

[0022] Furthermore, the bottom sealing plate 40 is fixedly installed at the opening at the bottom of the support frame 10. The bottom sealing plate 40 and multiple insulation plates 201 together form a heating cavity 103 with an opening at the top. Two heating plates 30 are symmetrically installed inside the heating cavity 103, and the angle between the heating plate 30 and the plane containing the opening of the heating cavity 103 is an acute angle. In this embodiment, the acute angle is 70°. However, it should be noted that this invention does not limit the specific angle and can be adjusted according to actual needs. Figure 2As shown, the two heating plates 30 form an inverted "V" shape. In this embodiment, a fixing member 104 is provided inside the heating cavity 103. One end of the fixing member 104 is fixedly installed on the inner wall of the insulation plate 201, and the other end of the fixing member 104 is bent and fixedly connected to the end of the heating plate 30, thereby making the heating plate 30 tilted. For the heating plate 30, a plate-shaped far-infrared heater is used in this embodiment. Far-infrared heating technology utilizes far-infrared rays emitted by a heat source to irradiate the material being heated. After the material absorbs the far-infrared rays, the internal molecules and atoms resonate to generate heat energy, thus achieving the purpose of heating. This is a process of radiative heat transfer. Using this technology can improve heating efficiency and save energy.

[0023] With the above structure, after designing the heating plate 30 to form an acute angle with the plane containing the opening of the heating cavity 103, the heating plate 30 is tilted towards the opening of the heating cavity 103. Therefore, when grilling, the food is placed at the opening of the heating cavity 103, and the heat emitted by the heating plate 30 can not only heat the air inside the heating cavity 103, but also directly act on the food to be grilled. This method improves the heat utilization rate of the heating plate 30, and more food can be grilled with the same amount of electricity, thereby reducing energy consumption.

[0024] In the above embodiments, combined with Figure 1 , Figure 2 As shown, the far-infrared electric oven also includes a corner sealing plate 50, which is symmetrically disposed at the corner of the opening of the heating chamber 103, leaving a heating port at the top of the heating chamber 103. A cover plate 105 is slidably installed on the heating port of the heating chamber 103. The cover plate 105 has grooves on opposite sides, allowing it to slide downwards vertically after being rotated to a vertical position, resting against the outer wall of the far-infrared electric oven. When grilling is needed, the cover plate 105 is opened, and the skewered food is placed at the heating port of the heating chamber 103 for grilling. After use, the cover plate 105 can be returned to its original position, covering the heating port to prevent foreign objects from entering the heating chamber 103. In this embodiment, a shelf 106 is also provided at the heating port for placing the skewered food.

[0025] Furthermore, in the above embodiments, refer to... Figure 1 , Figure 2As shown, the far-infrared electric oven also includes multiple protective plates 60, which are fixedly installed on the outside of the insulation plate 201 and the bottom sealing plate 40; and the protective plates 60 are provided with multiple through holes. In this embodiment, the insulation frame 20 and the bottom sealing plate 40 can minimize the diffusion of heat from the heating cavity 103 to the outside, thereby increasing the internal temperature of the heating cavity 103. However, some heat will still be dissipated through the insulation plate 201. To avoid this heat causing harm to the user, the design of the protective plates 60 can prevent the user from directly contacting the insulation plate 201 and prevent burns; at the same time, the through holes on the insulation plate 201 can quickly dissipate heat, preventing heat accumulation and excessively high local temperatures. It is understood that the protective plates 60 can be made of high-temperature resistant plastic.

[0026] To better utilize the far-infrared electric oven, a control box 70 is also provided, such as... Figure 1 , Figure 2 As shown, the control box 70 is located on one of the outer walls of the support frame 10. The heating plate 30 is controlled by the control box 70. It can be understood that the control box 70 contains circuit boards and other components to control the heating plate 30, including controlling the power and heating time of the heating plate 30. A display screen 701 is provided on the outer wall of the control box 70. The display screen 701 can be a touch screen to interact with the user and control and adjust parameters such as heating power and heating time.

[0027] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
