Description

Technical Field

[0001] This utility model relates to the technical field of baking ovens, specifically a baking oven with uniform baking function. Background Technology

[0002] As a commonly used piece of equipment in the food processing industry, the core objective of baking ovens is to achieve uniform heating of food through thermal radiation. Traditional baking ovens generally adopt a combination structure of fixed heating elements (such as electric heating tubes) and static food support racks. This design has the following significant drawbacks:

[0003] 1. Uneven heating problem: The heating element is usually fixed on the side wall, top or bottom of the oven, which causes the heat to be concentrated in a specific area. During static baking, the part of the food near the heat source is easy to burn, while the food far from the heat source or the central area is not heated enough. It is necessary to manually turn the food frequently to improve the uniformity, which is cumbersome and has limited effect.

[0004] 2. Inconvenient maintenance: The heating element is usually directly fixed to the inner wall of the box. Once damaged, replacement requires disassembling the entire box structure, which is costly and time-consuming. Utility Model Content

[0005] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes an oven with uniform baking function, comprising:

[0006] The housing is a movable housing;

[0007] A sealing door, hinged to one end face of the box, is used to seal the box.

[0008] The rotating shaft is rotatably mounted inside the housing.

[0009] Two pairs of crosses are fixedly installed on the outer surface of the rotating shaft;

[0010] A fan-shaped frame is provided on the cross;

[0011] A support net, fixedly installed inside the fan-shaped frame, is used to support food.

[0012] Several electric heating elements are installed on the inner wall of the box for baking the food.

[0013] Preferably, a plug-in block is fixedly installed on the side wall of the fan-shaped frame, and a plug-in groove is formed on the cross-shaped frame for plugging into the plug-in block.

[0014] Preferably, a plurality of through holes are formed in the side wall of the housing, and a plurality of connecting seats are provided on the outer side wall of the housing. One end of the connecting seat passes through the through hole and is fixedly connected to one end of the electric heating element. The connecting seat is fixedly connected to the housing by bolts.

[0015] Preferably, a control panel electrically connected to the electric heating element is fixedly installed on the outer surface of the sealed door, and a temperature sensor electrically connected to the control panel is fixedly installed on the inner surface of the sealed door.

[0016] Preferably, a support frame is fixedly installed on the upper end face of the housing, and a drive motor electrically connected to the control panel is fixedly installed on the upper end face of the support frame. The output end of the drive motor is fixedly connected to the top end of the rotating shaft.

[0017] Preferably, an opening is formed inside the sealed door, and an observation window is fixedly installed inside the opening;

[0018] The lower end face of the box is rotatably mounted with two pairs of casters.

[0019] The beneficial technical effects of this utility model are: by driving the cross and fan-shaped frame to rotate through the rotating shaft, the food on the carrying net is dynamically baked by the electric heating element from multiple angles, completely eliminating the dead angles of static baking;

[0020] The design of the connecting seat and through hole allows the damaged electric heating element to be pulled out from the outside of the housing by loosening the bolts, which facilitates maintenance.

[0021] The quick-release structure of the plug-in block and plug-in slot allows the fan-shaped frame to be disassembled and washed separately, solving the problem of residue retention in traditional fixed support nets and improving cleaning efficiency. Attached Figure Description

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] This utility model proposes a baking oven with uniform baking function, comprising:

[0031] Box 1, which is a movable box;

[0032] The movable box 1 can be moved flexibly, making it easy to transport.

[0033] Sealing door 2 is hinged to one end face of box 1 and is used to seal box 1;

[0034] The sealing door 2 is connected to the end face of the box 1 via a hinge, and when closed, it can form a sealed space in the box 1.

[0035] The rotating shaft 3 is rotatably installed inside the housing 1;

[0036] Crosses 4, in pairs, are fixedly installed on the outer surface of the pivot 3;

[0037] The rotating shaft 3 is vertically rotatably installed in the center of the box 1, and two pairs of crosses 4 are fixed circumferentially along the outer surface of the rotating shaft 3, so that the rotation of the rotating shaft 3 can drive the two pairs of crosses 4 to rotate simultaneously.

[0038] Fan-shaped frame 5, placed on cross 4;

[0039] The support net 6 is fixedly installed inside the fan-shaped frame 5 and is used to support food.

[0040] The fan-shaped frame 5 is detachably mounted on the cross 4, enabling modular and quick assembly and disassembly. The support net 6 is fixed inside the fan-shaped frame 5, directly supporting the food.

[0041] Several electric heating elements 7 are installed on the inner wall of the box 1 for baking food.

[0042] Several electric heating elements 7 can simultaneously bake the food on the top and bottom of the food carrier 6, making the baking of the food more uniform.

[0043] Specifically, a plug-in block 8 is fixedly installed on the side wall of the fan-shaped frame 5, and a plug-in groove 9 is formed on the cross 4 to plug into the plug-in block 8.

[0044] By inserting the plug block 8 into the plug slot 9 on the cross 4, modular quick assembly and disassembly can be achieved, making it convenient for staff to remove the fan-shaped frame 5 from the box 1 or connect the fan-shaped frame 5 to the cross 4.

[0045] Specifically, a number of through holes 10 are formed in the side wall of the housing 1, and a number of connecting seats 11 are provided on the outer side wall of the housing 1. One end of the connecting seat 11 passes through the through hole 10 and is fixedly connected to one end of the electric heating element 7. The connecting seat 11 is fixedly connected to the housing 1 by bolts.

[0046] The through hole 10 provides a passage for the electric heating element 7 and isolates the interior and exterior spaces of the enclosure. The connecting seat 11 is a metal flange-shaped base with inner and outer sides. The inner end extends into the enclosure and is fixedly connected to one end of the electric heating element 7. The outer end extends into an annular flange and has a bolt through hole. The bolt passes through the through hole of the connecting seat 11 from the outside of the enclosure 1 and is threadedly connected to the threaded hole pre-embedded on the outer wall of the enclosure 1. This allows the electric heating element 7 to remain stable inside the enclosure 1. The heat generated by the electric heating element 7 is dispersed to the outer wall of the enclosure 1 through the connecting seat 11 to dissipate heat and reduce the risk of local overheating. At the same time, the annular flange of the connecting seat 11 is tightly pressed against the outer wall of the enclosure 1 to prevent heat leakage and moisture intrusion. This structure, through the combination design of the external detachable connecting seat 11 and the through hole 10, completely moves the maintenance operation to the outside of the enclosure, making it more convenient for staff to maintain the electric heating element 7.

[0047] Specifically, a control panel 12 electrically connected to the electric heating element 7 is fixedly installed on the outer surface of the sealed door 2, and a temperature sensor 13 electrically connected to the control panel 12 is fixedly installed on the inner surface of the sealed door 2.

[0048] Temperature sensor 13 is fixedly installed on the inner surface of the sealed door 2, avoiding the area where food steam is directly sprayed. Its sensor probe is exposed to the air inside the cabinet 1, which facilitates the detection of the temperature inside the cabinet 1. Ceramic fiber insulation cotton is filled between temperature sensor 13 and sealed door 2 to block heat conduction from sealed door 2. Meanwhile, control panel 12 is fixedly installed on the outer surface of sealed door 2 in an inclined state. The tilt angle design makes it easy for the operator to observe. At the same time, the user can preset the temperature and time parameters of electric heating element 7 on control panel 12, so that control panel 12 outputs signals to adjust the power of electric heating element 7, and can display the data fed back by temperature sensor 13 in real time. The surface of control panel 12 is covered with high temperature resistant tempered glass, and the internal circuit board is potted with silicone for moisture protection.

[0049] Specifically, a support frame 14 is fixedly installed on the upper end face of the housing 1, and a drive motor 15 electrically connected to the control panel 12 is fixedly installed on the upper end face of the support frame 14. The output end of the drive motor 15 is fixedly connected to the top end of the rotating shaft 3.

[0050] The drive motor 15 is a three-phase asynchronous motor. The operator can preset the speed value of the drive motor 15 on the control panel 12, so that the output end of the drive motor 15 rotates and drives the rotating shaft 3, cross 4, fan-shaped frame 5 and bearing net 6 to rotate simultaneously, so that the electric heating element 7 can evenly bake the food on the top and bottom of the bearing net 6.

[0051] Specifically, an opening is formed inside the sealed door 2, and an observation window 16 is fixedly installed inside the opening;

[0052] The observation window 16 allows staff to easily monitor the baking process of the food, facilitating the adjustment of the heating power of the electric heating element 7.

[0053] Two pairs of casters 17 are rotatably mounted on the lower end face of the housing 1;

[0054] With the help of the casters 17, the box 1 can be moved flexibly, which facilitates transportation.

[0055] Working principle: After the food is placed on the support net 6 inside the fan-shaped rack 5, the sealing door 2 is closed to form a sealed space in the oven 1. The baking temperature and time are set through the control panel 12, and the electric heating element 7 is activated to heat the inside of the oven 1. At the same time, the drive motor 15 drives the rotating shaft 3 to rotate according to the preset speed, so that the cross 4, fan-shaped rack 5 and support net 6 fixed on the rotating shaft 3 rotate synchronously. During the rotation, the food continuously changes its position and receives heat radiation from the electric heating element 7 from multiple angles, achieving dynamic and uniform heating and completely eliminating the heat stagnation of traditional static baking. The temperature sensor 13 monitors the temperature inside the chamber 1 in real time and feeds it back to the control panel 12. The control panel 12 adjusts the power of the electric heating element 7 to maintain a constant temperature environment. The observation window 16 facilitates manual monitoring of the food status. After baking, the fan-shaped rack 5 can be separated from the cross 4 through the insertion slot 9 of the insertion block 8, and the food residue on the support mesh 6 can be removed and cleaned separately. If the electric heating element 7 is damaged, it can be removed and replaced by loosening the bolts on the connecting seat 11 from the outside of the chamber 1 through the through hole 10 without disassembling the chamber structure, which is convenient for people.
