Description

Technical Field

[0001] The utility model relates to the technical field of pastry processing equipment, and more particularly to an oven with a rotary air cooling function. Background Art

[0002] Existing ovens only have a baking function. Sometimes, baked products need to be cooled. The existing method can only take the products out and cool them externally. However, placing them externally needs to prevent contact with external insects and prevent nearby operators from accidentally touching and affecting the surface. After placing them externally, fans are generally used to directly blow air to accelerate cooling. However, the consequence of this is that the surface of the product, such as bread, will become very dry, affecting the taste.

[0003] However, if the products in the oven are cooled naturally in the oven, the cooling efficiency will be very low. Moreover, since the oven is a closed space, the water vapor mixed in the hot air inside will condense and cause water droplets to adhere to the surface of the product, affecting the taste of the product. The surface will easily become soft and collapse, affecting the product quality. Summary of the Invention

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an oven with a rotary air cooling function, which can directly and actively ventilate and cool the interior of the product after baking. It has good cooling effect and cools quickly, and will not come into contact with external people, objects, insects, etc., thereby ensuring a hygienic effect.

[0005] The solution of the utility model to solve the technical problem is:

[0006] An oven with a rotary air cooling function, comprising an oven body, a semi-cylindrical placement cavity extending rearwardly formed in the middle of a front wall of the oven body, a semi-arc door body movably connected to one side of the front wall of the oven body via a plurality of hinges, the semi-arc door body and the semi-cylindrical placement cavity forming a cylindrical cavity;

[0007] The front wall surfaces of the bottom plate and the top plate of the oven body are both formed with a semicircular raised plate portion extending forward, and the outer side wall of the semicircular raised plate portion is matched with the inner side wall of the top plate or the bottom of the door body;

[0008] An upper guide cover is fixed to the middle of the top surface of the bottom plate of the oven body, a horizontal connecting plate is fixed to the inner side of the lower portion of the upper guide cover, a cooling fan is fixed to the bottom surface of the horizontal connecting plate, an air outlet of the cooling fan is communicated with and aligned with the middle through hole of the horizontal connecting plate, the cooling fan is inserted into the middle through groove of the bottom plate of the oven body, and the middle through groove of the bottom plate of the oven body is communicated with the outside; side panels of the upper guide cover are connected to side air outlet pipes, and a top plate of the upper guide cover is connected to a middle air outlet pipe;

[0009] An exhaust through hole is formed in the middle of the top plate of the oven body.

[0010] An upper air guide shell is fixed to the top surface of the top plate of the oven body, an upper through hole is formed in the middle of the top plate of the upper air guide shell, the upper through hole is communicated with the upper air guide shell, and the exhaust through hole is communicated with the upper air guide shell.

[0011] Side guide plates are fixed to the front and rear of the top surface of the top plate of the upper air-guiding shell, and lower transverse guide grooves are formed on the opposite wall surfaces of the two side guide plates. The covering plate is pressed against the top surface of the top plate of the upper air-guiding shell, and the front and rear of the covering plate are inserted into the corresponding lower transverse guide grooves. The covering plate covers the upper through hole, and a connecting seat is fixed to one side of the top surface of the top plate of the oven body, and the electric push rod is fixed on the connecting seat, and the end of the push rod of the electric push rod is fixed to the connecting block fixed on the top surface of the covering plate.

[0012] The outstanding effects of the utility model are:

[0013] After the product is baked, it can directly and actively ventilate and perform internal cooling. It has good cooling effect and fast cooling, and will not come into contact with external people, objects or insects, thus ensuring hygiene.

[0014] Moreover, part of the cooling air can flow in a spiral shape along the inner wall of the cylindrical cavity to form a rotating wind, which greatly reduces the temperature of the inner wall of the cylindrical cavity. Another part blows vertically upward, and it will not blow directly onto the product. While ensuring that the product is cooled quickly, it prevents direct blowing, ensures the softness of the product surface, and will not be too dry to affect the taste. Moreover, the wind can discharge the hot air in the cylindrical cavity, that is, the water vapor contained therein can also be discharged, which makes it difficult for water droplets to condense on the surface of the product and become too soft and collapse, affecting the taste.

[0022] An exhaust hole 13 is formed in the middle of the top plate of the oven body 10 .

[0023] The ends of the side air outlet pipes 33 are movably connected to side baffles 331 via hinged shafts. Side baffles 331 precisely cover and are located close to the outlet ends of the side air outlet pipes 33. The top of the central air outlet pipe 34 is movably connected to an upper cover 341 via hinged shafts. The upper cover 341 rests against and covers the top of the central air outlet pipe 34. The side baffles 331 and upper cover 341 prevent a large amount of hot air from escaping during baking, providing a certain degree of blocking effect (but not complete blocking).

[0024] Furthermore, a plurality of lower supporting legs are fixed to the bottom surface of the bottom plate of the oven body 10, and the bottom surfaces of the lower supporting legs are pressed against the ground.

[0025] An upper air guide sleeve 15 is fixed to the bottom surface of the top plate of the oven body 10 around the exhaust through hole 13 .

[0026] An upper air guide shell 40 is fixed to the top surface of the top plate of the oven body 10 , and an upper through hole 41 is formed in the middle of the top plate of the upper air guide shell 40 . The upper through hole 41 is communicated with the upper air guide shell 40 , and the exhaust through hole 13 is communicated with the upper air guide shell 40 .

[0027] Furthermore, side guide plates 42 are fixed to the front and rear of the top surface of the top plate of the upper air-guiding shell 40, and lower transverse guide grooves 43 are formed on the opposite wall surfaces of the two side guide plates 42. The covering plate 44 is pressed against the top surface of the top plate of the upper air-guiding shell 40, and the front and rear of the covering plate 44 are inserted into the corresponding lower transverse guide grooves 43. The covering plate 44 covers the upper through hole 41, and a connecting seat is fixed to one side of the top surface of the top plate of the oven body 10, and an electric push rod 45 is fixed on the connecting seat, and the end of the push rod of the electric push rod 45 is fixed to the connecting block fixed on the top surface of the covering plate 44.

[0028] A bottom protective layer 441 is fixed to the bottom surface of the cover plate 44 , and the bottom surface of the bottom protective layer 441 is in close contact with the top surface of the top plate of the upper air guide housing 40 .

[0029] A material unloading trolley frame 50 is placed on the top surface of the bottom plate of the oven main body 10, and the material unloading trolley frame 50 is in the semi-cylindrical placement cavity 11. A plurality of trolley wheels 51 are installed on the left and right bottom surfaces of the bottom plate of the material unloading trolley frame 50, and the bottom surfaces of the trolley wheels 51 are pressed against the top surface of the bottom plate of the oven main body 10. Vertical support columns 52 are fixed on the left, right and rear parts of the top surface of the bottom plate of the material unloading trolley frame 50, and a plurality of semi-circular arc-shaped connecting blocks 53 are stacked up and down, and their outer side walls are welded and fixed to the side walls of the three vertical support columns 52.

[0030] The lower part of the inner wall of the semicircular arc connecting block 53 is formed with a semi-arc-shaped conical wall panel 54 extending upward and toward the middle, and the top of the conical wall panel 54 is formed with an extended edge portion 55 extending radially toward the inner wall of the semicircular arc connecting block 53. The baking tray is placed on the top surface of the corresponding extended edge portion 55, and the inner side of the bottom surface of the baking tray is fixed or formed with an arc-shaped protrusion, and an arc-shaped clamping protrusion strip is formed on the lower inner side wall of the arc-shaped protrusion. The arc-shaped protrusion is located between the extended edge portion 55 and the semicircular arc connecting block 53, and the arc-shaped clamping protrusion strip is located below the corresponding extended edge portion 55 and pressed against the bottom surface of the extended edge portion 55.

[0031] When using this embodiment, the unloading pusher frame 50 is first placed in the semi-cylindrical placement cavity 11. Then, the product to be processed, such as bread, can be placed on the baking tray, and then placed on the corresponding extended edge portion 55 and moved forward so that the inner side wall of the arc-shaped protrusion is pressed against the side wall of the corresponding extended edge portion 55. At this time, the arc-shaped locking protrusion strip is located below the corresponding extended edge portion 55, so that the baking tray is not easily removed from the corresponding extended edge portion 55.

[0032] Then, close the door 20 and start baking. After completion, when the product needs to be cooled, turn on the cooling fan 32. After it is turned on, the wind will push open the side baffles 331 and the upper cover 341 (the side baffles 331 and the upper cover 341 are relatively light in weight), allowing the wind to enter the cylindrical cavity. The gas discharged from the side air outlet pipe 33 can rotate and flow upward along the inner wall of the cylindrical cavity to cool the inner wall of the cylindrical cavity, while the gas coming out of the middle air outlet pipe 34 flows in the cylindrical cavity to cool the product therein. Since it is not blown directly on the product, the surface of the product will not be too dry, thereby ensuring the quality of the product.

[0033] The blown wind is discharged from the upper through hole 41. At this time, the cover plate 44 is retracted by the push rod of the electric push rod 45 and is moved out so that the upper through hole 41 is not covered, so that the wind can be blown out. When blowing out again, it discharges the water vapor in the cylindrical cavity together, preventing condensed water droplets from adhering to the surface of the product, thereby ensuring the quality of the product.

[0034] After the product is baked, it can be directly and actively ventilated for internal cooling. The cooling effect is good and fast, and there is no contact with external people, objects or insects, etc., thus ensuring a hygienic effect.

[0035] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of patent protection of the present invention shall be defined by the claims.
