Description

Technology Field

[0001] The present invention relates to a door device for accessing the housing of a meat processing device, and more specifically, to a door device for accessing the housing of a meat processing device configured to allow processing of meat processing food while moving through a net that moves in a spiral type, by configuring the door installed in the housing of the meat processing device to be openable and closed in a sliding manner, thereby enabling the opening and closing of the door even when the meat processing device is installed in a narrow space. Background Technology

[0003] Recently, many diverse processed foods that can be heated and consumed immediately are being released for busy modern people.

[0004] These processed foods, especially meat products, are cooked by applying heat to the moving meat products.

[0005] That is, a conventional device for cooking general processed meat products, i.e., a heating device, is composed of a moving part having a plurality of rotating rollers at regular intervals that can be rotatably rotated, and a plurality of electric heaters provided at regular intervals to radiate heat in response to power application to the upper and lower parts of the moving part so as to cook the processed meat products.

[0006] Therefore, when a processed meat product is placed on the moving part of the above-described device, it is cooked by the heat emitted from the electric heater while moving.

[0007] However, the aforementioned conventional general heating device had a problem of high power consumption and increased electricity costs because multiple electric heaters were provided at the top and bottom to cook processed meat products moving through the moving part as described above.

[0008] In addition, conventional general heating devices have a problem in that they directly heat and cook moving processed meat products through electric heaters as described above, which inevitably causes a significant loss of moisture contained in the processed meat products.

[0009] In addition, conventional general heating devices cook processed meat products using multiple electric heaters as described above, so there was a problem in that it was not easy to control the heat provided by the electric heaters when cooking different types of products, such as ham, while cooking meat.

[0010] Taking these points into consideration, a gas-type spiral oven was proposed in patent application number 10-2018-0116881.

[0011] Upon examination, a conventional general gas-type spiral machine comprises: a housing having an inlet and an outlet formed on one side and the other side; a supply unit and an outlet unit positioned at each side of the inlet and outlet of the housing to supply and discharge processed meat products; a pair of first and second drums spaced apart from each other and rotatably provided inside the housing, which are rotatably provided by receiving driving force from a driving motor installed at the bottom of the housing; a conveying net provided to move in a spiral manner on the first and second drums, which is wound in an endless track type to convey the processed meat products along the supply unit, the first and second drums, and the outlet unit; a heating means fixedly installed on the upper part of the housing to heat the processed meat products conveyed through the conveying net; and a net cleaning means installed on one side of the bottom of the housing to clean the conveying net while it is being conveyed, thereby preventing the taste of the processed meat products from deteriorating and preventing by-products from adhering, so as to provide clean processed meat products. It is composed.

[0012] Here, the heating means described above comprises: first and second burner sections, each installed on one side of a heating cover section fixedly installed on both upper sides of the housing and configured to be ignitable by the control of a control unit; first and second heat exchange sections, each installed on one side of the first and second burner sections and configured to exchange heat discharged from the first and second burner sections by being installed within the heating cover section; a hot air blower section, each installed on one side of the first and second heat exchange sections and configured to be driven in response to the control of the control unit to draw in air inside the housing and blow it toward the first and second heat exchange sections, thereby enabling the meat processing food to be cooked by the circulating heat; and a plate formed in a semi-circular shape, each located below the hot air circulation blower section, with one end fixed to the upper part of the first and second drums respectively and the other end fixed to a fixing bar fixed to the first and second drums respectively, wherein the heat exchanged by the hot air circulation blower section is evenly discharged and flowed downwards on the plate. It is composed of a heat discharge plate having a plurality of heat discharge holes formed at regular intervals in a radial direction, and a heat blocking plate positioned below the heat discharge plate, with one end fixed to the outer surface of the first and second drums respectively and the other end fixed to the fixing bar respectively, so that the heat blown is reflected toward the transfer net and diffused into the housing by being spaced apart so that the transfer net moves between the heat discharge plate and the heat discharge plate.

[0013] However, conventional gas-type spiral ovens configured in this manner have the disadvantage that, due to the aforementioned configurations, they are designed to cook processed meat products by indirect heating rather than direct heating while moving them through a conveyor net that moves in a spiral manner, thereby allowing the outside to be cooked crisply while the inside to be cooked evenly, and also protecting the meat products from losing their juices, but they do not have a door for accessing the housing, making it difficult to enter the housing.

[0072] In this way, when the first and second cam parts (173a, 174a') release pressure on the opening / closing door (130), the opening / closing rotary handle part (160) is rotated counterclockwise.

[0073] The driving gear (152) of the driving gear member (150) rotates counterclockwise by the rotation of the above-mentioned opening / closing rotary handle part (160).

[0074] As the driving gear (152) of the driving gear member (150) rotates counterclockwise, the moving gear member (140) moves to the left by the movement of the rack gear (141) meshed with the driving gear (152), thereby opening the door (130) to the left along the upper and lower guide rails (110, 120).

[0075] As described above, the opening / closing door (130) is configured to open and close in a sliding manner rather than in a rotating manner, so that the opening / closing door (130) can be opened and closed even if the meat processing device is installed in a narrow space.

[0076] The foregoing description is merely an illustrative explanation of the technical concept of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications and variations within the scope of the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are intended to explain, not limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments. The scope of protection of the present invention shall be interpreted by the claims below, and all technical concepts within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
