Description

Technical Field

[0001] This utility model relates to the field of toasters, and in particular to a furnace structure for toasters. Background Technology

[0002] The bread slots in most commercially available toasters are not adjustable, meaning they can only be used to toast slices of bread of regular thickness. They cannot be used to toast extra-thick slices of food vertically, like bread slices. Therefore, when users need to toast slices of food thicker than a regular bread slice, such as sandwiches or mini hamburgers, they usually have to choose between baking in an oven or heating in a frying pan, which is quite inconvenient.

[0003] Many inventors have attempted to solve the problem that common toasters cannot vertically toast very thick slices of food like bread slices. For example, Chinese Patent Announcement CN201131663Y uses a method where at least one heating plate assembly is movable and connected to a lever. Chinese Patent Announcement CN201223314Y uses a method where a grid frame translation mechanism is installed inside the oven cavity, including a lever pivotally mounted on the lower outer side of the right side plate. Another example is Chinese Patent Announcement CN101849780B, which uses a toaster oven cavity structure comprising three heating frame assemblies: front, middle, and rear. The middle heating assembly is slidably disposed within the oven cavity, and consists of a support, a heating plate assembly located inside the support, and four sliding shafts located at the four corners of the support. This structure enables the middle heating assembly to translate back and forth.

[0004] Based on the disclosed technical methods, although all of them can achieve the goal of adjusting the bread slot width to bake slices of different thicknesses, the above solutions have at least the following shortcomings and technical problems that need to be improved: The structure is relatively complex and the manufacturing process is quite difficult; 2. The bread slot width needs to be manually adjusted and cannot automatically adapt to the thickness of the inserted slices of food, making it inconvenient to use. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this invention is to propose a new oven cavity structure, particularly a new toaster oven baking cavity structure that automatically and adaptively adjusts the width of the bread slot according to the thickness of the inserted sliced ​​food.

[0006] To achieve this objective, the present invention adopts the following technical solution: A furnace cavity structure includes a baking cavity formed by a left side plate, a rear side plate, a right side plate, and a front side plate; it also includes a central heating element. The middle heating element is plate-shaped, and its lower end is assembled with the lower part of the baking cavity through an elastic support. The middle heating element is subjected to force through the elastic support and generates a stroke that elastically deflects to the left and right in the baking cavity. Heating plates are provided on the inner sides of both the left and right side panels.

[0007] Preferably, the central heating element is plate-shaped and is vertically installed inside the baking cavity. The central heating element is parallel to the left and right side plates, and there are gaps between the two sides of the central heating element and the front and rear side plates. The lower part of the front and rear side panels is provided with mounting connectors, and the elastic support member at the lower part of the heating component is one of an elastic plate, an elastic strip, or an elastic column.

[0008] Preferably, a power switch for the heating plate corresponding to the left and right side panels is provided on the front or rear side panel at a position to the left or right relative to the central heating component. When the central heating component shifts, the power switch in the shift direction is triggered to cut off the power.

[0009] Preferably, the top of the side end of the heating element is provided with a spring that connects to the left or right side plate.

[0010] Furthermore, it also includes a wire mesh frame assembly, which includes sheet-shaped grilling racks arranged opposite each other on the left and right sides. The left side plate and the middle heating element form a left bread slot, and the wire mesh frame assembly is arranged in the left bread slot with the left grilling rack close to the left side plate and the right grilling rack close to the middle heating element. The right side plate and the middle heating element form a right bread slot, and the wire mesh frame assembly is arranged in the right bread slot with the right grilling rack close to the right side plate and the left grilling rack close to the middle heating element. The grill racks are all vertically oriented, with the lower ends of the grill racks pivotally connected to the lower parts of the front and rear side panels, respectively. The heating element has guide rods on both sides of the grill. The guide rods are located on both sides of the grill. The front and rear side plates have guide grooves that are adapted to the guide rods at the corresponding positions. The pivot point of the left heating element of the middle heating component is directly below the starting point of the guide groove, and the pivot point of the right heating element of the middle heating component is directly below the ending point of the guide groove. The start and end points of the guide groove are connected in a straight line, and the guide rod rotates over the space between the start and end points of the guide groove.

[0011] Furthermore, the baking cavity is equipped with an openable V-shaped baking rack with an upper opening, which is formed by two grids or mesh panels pivotally connected at the bottom and has an extended handle at the top.

[0012] Furthermore, the openable V-shaped grill with an upper opening can have a perforated metal sheet attached to its inner wall. The through holes of the perforated metal sheet can overlap with the through holes of the V-shaped grill, or be partially and adjustablely blocked by the mesh strips of the V-shaped grill.

[0013] Furthermore, the porous metal sheet is square, and the cross-section of the surface through holes is circular, elliptical, or slit-shaped.

[0014] Furthermore, the surface of the porous metal sheet is distributed with raised and recessed patterns.

[0015] One of the above technical solutions includes the following beneficial effects: The present invention divides the baking cavity into two parts, a left bread slot and a right bread slot, by means of a central heating component. The central heating component, which is set in the middle, is installed in the baking cavity through an elastic support, so that the central heating component has the function of elastically deflecting to the left and right. In this way, the space between the left bread slot and the right bread slot can be adjusted. When the central heating component elastically deflects to the left, the space in the right bread slot will become larger, so that thicker slices of food can be inserted. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a cross-sectional schematic diagram of the present invention; Figure 3 This is a schematic diagram of the structure of the heating component of this utility model.

[0017] The components include: left side plate 1, rear side plate 2, middle heating element 3, right side plate 4, space frame assembly 5, front side plate 6, elastic support element 7, and guide groove 8. Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1-2 The furnace structure shown includes a baking cavity formed by a left side plate 1, a rear side plate 2, a right side plate 4, and a front side plate 6; it also includes a central heating element 3. The middle heating component 3 is plate-shaped. The lower end of the middle heating component 3 is assembled with the lower part of the baking cavity through the elastic support 7. The middle heating component 3 is subjected to force by the elastic support 7 and generates a stroke that elastically deflects to the left and right in the baking cavity. Heating plates are provided on the inner sides of both the left side panel 1 and the right side panel 4.

[0020] This invention divides the baking cavity into two parts, a left bread slot and a right bread slot, through the central heating component 3. The central heating component 3, located in the middle, is installed in the baking cavity through an elastic support 7, giving it the function of elastically deflecting to the left and right. In this way, the space between the left and right bread slots can be adjusted. When the central heating component 3 elastically deflects to the left, the space in the right bread slot becomes larger, allowing thicker slices of food to be inserted.

[0021] like Figures 2-3 As shown, the middle heating component 3 is plate-shaped and is vertically installed inside the baking cavity. The middle heating component 3 is parallel to the left and right side plates, and there are gaps between the two sides of the middle heating component 3 and the front and rear side plates 6 and 2. The lower part of the front side plate 6 and the rear side plate 2 is provided with mounting connectors, and the elastic support 7 at the lower part of the heating component 3 is one of an elastic plate, an elastic strip or an elastic column.

[0022] The central heating element 3 is vertically housed in the baking cavity, and its lower end is installed in the baking cavity through the elastic support 7, thereby ensuring that the central heating element 3 can swing within the baking cavity; any side of the central heating element 7 can form a double-sided heating function with the opposite left and right side plates; the elastic deflection generated by the central heating element 3 can increase the baking space.

[0023] In addition, a power switch for the heating plate of the left and right side panels is provided on the front side panel 6 or the rear side panel 2 at a position to the left or right relative to the central heating component 3. When the central heating component 3 is offset, the power switch in the offset direction is triggered to cut off the power.

[0024] When the central heating element 3 shifts to the left, it triggers the power switch of the heating plate on the left side panel, and the power to the heating plate on the left side panel is turned off. Similarly, when the central heating element 3 shifts to the right, it triggers the power switch of the heating plate on the right side panel, and the power to the heating plate on the right side panel is turned off. In this way, when the enlarged bread cavity is in use, the corresponding heating plate of the other bread cavity, which is occupied and in an idle state, can be turned off.

[0025] In addition, the top of the side end of the heating component 3 is provided with a spring that connects to the left side plate 1 or the right side plate 4.

[0026] The top of the side of the heating element 3 is provided with a spring that connects to the left side plate 1 or the right side plate 4. By setting the spring, the heating element 3 and the left side plate 1 or the right side plate 4 are connected. The pulling force of the spring can clamp the food that is placed in it.

[0027] As a supplement to the above technology, a wire mesh frame assembly 5 is also included. The wire mesh frame assembly includes sheet-shaped baking racks arranged opposite each other on the left and right sides. The left side plate 1 and the middle heating element 3 form a left bread slot. The wire mesh frame assembly 5 is arranged in the left bread slot with the left baking rack close to the left side plate and the right baking rack close to the middle heating element 3. The right side plate 4 and the middle heating element form a right bread slot. The wire mesh frame assembly 5 is arranged in the right bread slot with the right baking rack close to the right side plate and the left baking rack close to the middle heating element 3. The grill racks are all vertically arranged, and the lower ends of the grill racks are pivotally connected to the lower parts of the front side plate 6 and the rear side plate 2, respectively. The heating element 3 has guide rods on both sides of the grill. The guide rods are located on both sides of the grill. The front side plate 6 and the rear side plate 2 have guide grooves 8 that are adapted to the guide rods at the corresponding positions. The pivot point of the left side grilling mesh of the middle heating element 3 is directly below the starting point of the guide groove 8, and the pivot point of the right side grilling mesh of the middle heating element 3 is directly below the ending point of the guide groove 8. The start and end points of the guide groove 8 are connected in a straight line, and the guide rod rotates over the space between the start and end points of the guide groove 8.

[0028] The grilling meshes on the left and right sides of the central heating element 3 move along the guide groove 8 via guide rods. This design ensures that the grilling meshes on the left and right sides of the central heating element 3 have an opening stroke when they need to be opened due to compression.

[0029] In addition, the baking cavity is equipped with an openable V-shaped baking rack with an upper opening, which is formed by two grids or mesh panels pivotally connected at the bottom and has an extended handle at the top.

[0030] There is no assembly relationship between the grill and the baking cavity; the function of the grill is to hold and prepare sliced ​​food.

[0031] In addition, the openable V-shaped grill with an upper opening can have a perforated metal plate attached to its inner wall. The through holes of the perforated metal plate can overlap with the through holes of the V-shaped grill, or be partially and adjustablely blocked by the mesh strips of the V-shaped grill.

[0032] The porous metal sheet is used to block heat radiation. It absorbs the auxiliary heat and then transfers heat to the food it holds.

[0033] Furthermore, the porous metal sheet is square, and the cross-section of the surface through holes is circular, elliptical, or slit-shaped.

[0034] Furthermore, the surface of the porous metal sheet is distributed with raised and recessed patterns.

[0035] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
