Description

Technical Field

[0001] This utility model relates to the field of cake heating technology, and in particular to a device for uniformly heating coffee-flavored cakes. Background Technology

[0002] Current coffee-flavored cake heating devices generally suffer from systemic technical bottlenecks in both industrial production and home baking scenarios. The core problem lies in the dynamic mismatch between heat distribution and the evolution of cake properties. Traditional heating equipment (such as single-layer ovens based on radiant heat sources or static hot plate conduction devices) fails to fully consider the complex matrix characteristics of coffee-flavored cakes in their design logic—due to the properties of coffee extracts, the cakes are prone to uneven heating, which affects baking quality.

[0003] Specifically, the heating unit of current cake baking equipment is generally located on one side of the oven, resulting in different distances between each coffee-flavored cake and the heat source. This can easily lead to uneven heating during baking, affecting the baking quality. Utility Model Content

[0004] In view of the shortcomings mentioned above, this utility model provides a device for uniformly heating coffee-flavored cakes.

[0005] The present invention adopts the following technical solution:

[0006] An apparatus for evenly heating coffee-flavored cakes, characterized in that the apparatus comprises:

[0007] The shell has an internal heating space, and heating units are installed on the inner wall of the heating space.

[0008] A turntable is rotatably connected within the heating space;

[0009] Multiple placement trays are arranged in a ring on the annular surface of the turntable. Each placement tray is used to place a coffee-flavored cake to be heated, and the placement tray can rotate relative to the turntable. The axis of rotation of the placement tray is perpendicular to the axis of rotation of the turntable.

[0010] A worm gear is rotatably connected to one side of the housing. The pitch of the helical teeth of the worm gear matches the outer diameter of the placement disk, and the helical teeth of the worm gear mesh with each of the placement disks, so that the rotation of the worm gear drives the placement disk to rotate upward or downward about the axis of the turntable.

[0011] In one possible implementation, the worm is hollow inside, and a heating tube is inserted inside the worm, with one end of the heating tube located outside the worm and fixed relative to the housing.

[0012] In one possible implementation, the bottom of the housing is provided with a clearance opening, and the bottom of the housing is fixedly covered by a bottom shell with the clearance opening. The two ends of the worm gear are connected to the two ends of the bottom shell, and a mounting plate is fixed on one side of the bottom shell. One end of the heating tube extends out of the bottom shell, and the heating tube is helically connected to nuts on both sides of the mounting plate.

[0013] In one possible implementation, multiple connecting rods are fixedly arranged in a circumferential array on the toroidal surface of the turntable, and bolts are helically connected to the end faces of the connecting rods. The placement plate includes a rotating plate, a placement frame, and a cover ring. The placement frame is a circular frame. A first bearing is fixed at the center of the rotating plate. The bolts pass through the inner ring of the first bearing and are helically connected to the connecting rods, thereby fixing the first bearing to the connecting rods. The placement frame is fixed to the side of the rotating plate facing away from the connecting rods. The cover ring is detachably connected to the opening of the placement frame.

[0014] In one possible implementation, the inner side of the opening end of the placement frame is provided with an internal thread, and the cover ring is helically embedded into the placement frame in connection with the internal thread.

[0015] In one possible implementation, the upper surface of the housing is provided with a placement opening, and a cover is hinged to the housing at the placement opening, so that the cover is flipped relative to the housing, and after the cover is flipped to fit against the housing, the cover covers the placement opening.

[0016] In one possible implementation, the bottom of the housing is provided with a clearance opening, and the bottom of the housing is fixedly covered by a bottom shell with the clearance opening. The two ends of the worm are connected to the two ends of the bottom shell, and the upper end of the helical teeth of the worm protrudes from the bottom shell, so that the helical teeth of the worm mesh with the two adjacent placement boxes.

[0017] In one possible implementation, the housing includes an upper shell and a sealing plate, the heating space is disposed inside the upper shell, one side of the upper shell is open, the sealing plate is fixed to the open side of the upper shell, and the sealing plate covers the open side of the upper shell.

[0018] In one possible implementation, a drive motor is fixed to one end of the outer shell, and the output shaft of the drive motor is connected to one end of the worm gear.

[0019] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model uses multiple placement trays for placing coffee-flavored cakes distributed on the annular surface of the turntable. The spiral teeth of the worm gear mesh with two adjacent placement boxes, so that the rotation of the worm gear can drive the placement trays to rotate around the axis of the turntable. This allows each placement tray to rotate relative to the heating unit in the heating space of the shell, so that the coffee-flavored bread placed in each placement tray is heated evenly. This allows the coffee flavor substances to fully penetrate into the bread fiber structure during the heating process, while avoiding the aroma loss or crust hardening caused by local overheating, which is beneficial to improving the baking quality.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0029] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0031] This invention provides a device for evenly heating coffee-flavored cakes, as shown in the attached diagram. Figures 1 to 3 As shown, the device includes a housing 1, a turntable 2, multiple placement trays 3, and a worm gear 4. The housing 1 forms a heating space 101, within which the turntable 2 and placement trays 3 are disposed. The placement trays 3 are used to hold coffee-flavored cakes to be heated. Heating units 51, which can be arc-shaped electric heating plates, are installed on the inner wall of the heating space 101 to convert electrical energy into heat energy to heat the coffee-flavored cakes inside the housing 1.

[0032] As attached Figure 2 , 7 As shown in Figure 8, multiple placement trays 3 are arranged in a ring on the annular surface of the turntable 2. Each placement tray 3 is used to place a coffee-flavored cake to be heated, and the placement tray 3 can rotate relative to the turntable 2. The specific connection structure can be as shown in the attached figure. Figure 7 As shown, multiple connecting rods 21 are arranged in a circular array around the annular surface of the turntable 2, and bolts 22 are spirally connected to the end faces of the connecting rods 21. The placement tray 3 includes a rotating plate 31, a placement frame 32, and a covering ring 33. The placement frame 32 is a circular frame with a hollowed-out annular surface. This hollowed-out structure allows the coffee-flavored cake placed inside the placement frame 32 to communicate with the hot air in the heating space 101, thereby ensuring that the coffee-flavored cake is fully heated. A first bearing 34 is fixed to the center of the rotating plate 31, and bolts 22 pass through the inner ring of the first bearing 34 and spirally connect to the connecting rods 21, thus fixing the first bearing 34 to the connecting rods 21. The structure connected by the first bearing 34 restricts the placement tray 3 to rotate only relative to the connecting rods 21 of the turntable 2. The placement frame 32 is fixed to the side of the rotating plate 31 facing away from the connecting rods 21. The fixing method can be that the rotating plate 31 is installed to the connecting rods 21 and then the placement frame 32 is fixed to the rotating plate 31. The fixing method can be through screw fixing or direct welding fixing. The covering ring 33 is detachably connected to the opening of the placement frame 32. After the coffee-flavored cake is placed into the placement frame 32, the covering ring 33 is inserted into the opening end of the placement frame 32 to confine the cake within the placement frame 32. Furthermore, the inner side of the opening end of the placement frame 32 is provided with an internal thread, and the annular surface of the covering ring 33 is provided with an external thread. The external thread of the covering ring 33 is screwed into the internal thread of the placement frame 32, thereby achieving a detachable connection between the covering ring 33 and the placement frame 32. The covering ring 33 is screwed into the placement frame 32.

[0033] Continue to refer to the appendix Figure 1 The housing 1 includes an upper shell 11, a sealing plate 12, and a bottom shell 13. A heating space 101 is disposed inside the upper shell 11. One side of the upper shell 11 is open, used to install the heating unit 51, the turntable 2, and the placement plate 3 into the heating space 101 of the upper shell 11. The sealing plate 12 is fixed to the open side of the upper shell 11 by through screws, so that the sealing plate 12 covers the open side of the upper shell 11. Preferably, the upper shell 11 can be fixed to a frame to keep the present invention stable. In addition, a central fixed bearing seat is fixed outside the upper shell 11, and a central fixed bearing seat is also fixed to the sealing plate 12. The two ends of the turntable 2 are respectively fixed to the bearing seats of the upper shell 11 and the bearing seats of the sealing plate 12 to restrict the turntable 2 to rotate within the heating space 101, and the rotation axis of the turntable 2 is perpendicular to the rotation axis of the placement plate 3. Additionally, the upper surface of the upper shell 11 is provided with a placement opening (not shown in the attached diagram). A coffee-flavored cake is placed into the heating space 101 through this opening. Specifically, when the turntable 2 slowly rotates to the placement opening, the coffee-flavored cake is placed into the placement frame 32, and then the covering ring 33 is inserted into the placement frame 32, confining the coffee-flavored cake within it. The upper shell 11 is also hinged to a cover 14 at the placement opening, allowing the cover 14 to flip relative to the shell 1. After placing cakes in the placement frames 32 of each placement tray 3, the cover 14 is flipped to fit snugly against the shell 1, covering the placement opening and thus creating a sealed space within the heating space 101.

[0034] Please refer to the appendix. Figure 2 The bottom of the upper shell 11 is provided with a clearance opening 102. The two ends of the worm gear 4 are connected to the two ends of the bottom shell 13, and the upper ends of the helical teeth 41 on the surface of the worm gear 4 protrude from the bottom shell 13. These helical teeth 41 are helical protrusions formed on the surface of the worm gear 41. The bottom shell 13 is fixed to the bottom of the upper shell 11 to cover the clearance opening 102, allowing the worm gear 4 to be rotatably connected to the bottom of the shell 1. (See attached...) Figure 7 and 8 As shown, the pitch of the helical teeth 41 of the worm gear 4 matches the outer diameter of the placement tray 3 (i.e., the placement frame 32), so that the helical teeth 41 of the worm gear 4 mesh with the two adjacent placement trays. This causes the worm gear 4 to rotate, driving the placement tray 3 to rotate upward or downward about the axis of the turntable 2. During the rotation of the worm gear 4, each placement tray 3 rotates upward or downward one by one. Specifically, when the worm gear 4 rotates forward, each placement tray 3 rotates upward one by one; when the worm gear 4 rotates in reverse, each placement tray 3 rotates downward one by one. Furthermore, a drive motor 42 is fixed to one end of the bottom shell 13. The output shaft of the drive motor 42 is connected to one end of the worm gear 4, so that the drive motor 42 can drive the worm gear 4 to rotate, thereby driving the turntable 2 to rotate within the heating space 101. This causes each placement tray 3 to rotate relative to each heating unit 51 within the turntable 2, achieving uniform heating. This ensures that the coffee-flavored bread placed in each placement tray 3 is heated evenly.

[0035] Please refer to the appendix. Figure 2 As shown, the worm gear 4 is hollow inside, and a heating tube 52 is installed inside the worm gear 4. One end of the heating tube 52 is located outside the worm gear 4 and fixed relative to the housing 1. This method heats the worm gear 4, allowing the sides of the spiral teeth 41 of the worm gear 4 to transfer heat to the placement trays 3 during contact, achieving contact heating of the placement trays 3. Furthermore, during the contact between the spiral teeth 41 and the placement trays 3, the placement trays 3 are also driven to rotate around the bolt 22 as the axis, ensuring that all surfaces of the placement trays 3 are in contact with the heated worm gear 4. This improves the uniformity of heating of the placement trays 3, thereby improving the uniformity of heating the coffee-flavored bread. (See attached diagram.) Figure 4 and 5 A mounting plate 15 is fixed to one side of the bottom shell 13. The mounting plate 15 has a C-shaped structure and is fixed to the side of the bottom shell 13. One end of the heating tube 52 extends out of the bottom shell 13, and nuts 54 are screwed onto both sides of the mounting plate 15 to fix the heating tube 52 relative to the shell 1. The other end of the heating tube 52 is fixed to a second bearing 53 inside the worm gear 4. The second bearing 53 is adapted to be embedded in the hollow inner hole of the worm gear 4, so that the second bearing 53 supports the heating tube 52 and suspends it inside the worm gear 4 without affecting the rotation of the worm gear 4.

[0036] Preferably, a temperature sensor can be configured inside the housing 1 to sense the heating temperature inside the heating space. Furthermore, the present invention can be configured with a control system to receive the temperature signal from the temperature sensor and display it on a screen. At the same time, the control system can also be used to control the working status of the heating unit 51, the heating tube 52 and the drive motor 42, so that the present invention can operate normally and orderly.

[0037] In summary, this invention utilizes a multi-tiered tray 3 for holding coffee-flavored cakes, distributed around the annular surface of the turntable 2. The worm gear 4's helical teeth 41 engage with adjacent trays, causing the tray 3 to rotate about the axis of the turntable 2. This allows each tray 3 to rotate relative to the heating unit 51 within the heating space 101 of the housing 1, ensuring uniform heating of the coffee-flavored bread within each tray 3. Simultaneously, the contact between the helical teeth 41 and the tray 3 also causes the tray 3 to rotate about the bolt 22, ensuring all surfaces of the tray 3 are in contact with the heated worm gear 4. This improves the uniformity of heating the tray 3, thereby enhancing the uniformity of heating the coffee-flavored bread. Therefore, this invention ensures uniform heating of the coffee-flavored cake, allowing the coffee flavor compounds to fully penetrate the bread's fiber structure during heating, while preventing aroma loss or crust hardening due to localized overheating.

[0038] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
