Smokeless grill plate with dual ventilation paths

Abstract

To provide a smokeless grill plate having two ventilation paths. [Solution] An installation space is formed inside the main housing (10), and the upper surface of the installation space is structured to protrude above the upper surface of the main housing. A left ventilation fan and a right ventilation fan are provided on the lower left and right sides of the installation space, respectively. Air blown by the rotation of one ventilation fan is directed through ventilation holes formed in the side panel of the insulated oil pan (40) into the space above one side of the grill plate (60), guiding the smoke airflow to the other side of the grill plate, forming a first ventilation path. The suction force of the other ventilation fan draws the smoke airflow through the ventilation holes, guides it through the space between the insulated oil pan and the main housing, and then guides it into the ventilation fan, finally discharging it outside the main housing, forming a second ventilation path. The two airflow paths formed by the left ventilation fan and the right ventilation fan efficiently guide and remove smoke generated during grilling.

Description

[Technical Field]

[0001] The present invention relates to the technical field of kitchen appliances, and more particularly to a smokeless grill plate with dual ventilation paths. [Background technology]

[0002] With advances in technology, grill plates are no longer limited to traditional dedicated appliances; they can now be combined with electric heating tubes to function as a grilling plate, allowing for multi-functional applications such as deep-frying and grilling, and can also be used in yakiniku machines and air fryers. However, conventional grill plates lacked a smoke suction device, which created the problem of large amounts of smoke being generated during use, reducing usability.

[0003] Existing products use a closed-loop ventilation path with a single fan, but because the fan is located on one side of the housing, the ventilation path is single, and the long ventilation path reduces wind power and insufficient suction, resulting in insufficient smoke extraction.In addition, the separate metal insulation plate and oil collection tray make the structure complex, resulting in high manufacturing costs and making cleaning and removal difficult.

[0004] Furthermore, the left handle connecting the heating tube to the control box marred the unity of the appearance, necessitating two-handed operation and increasing manufacturing costs.Furthermore, the heating rod and main housing were fixedly connected, making disassembly, cleaning, and maintenance difficult. Summary of the Invention [Problem to be solved by the invention]

[0005] This device solves the problems of the prior art by providing a smokeless grill plate with dual ventilation paths, with the heating rod and control host detachably mounted on the main housing. The left and right ventilation fans increase wind power to maximize smoke exhaust efficiency during grilling, and the insulated oil tray, which integrates insulation and oil collection functions, reduces the number of parts and manufacturing costs.

[0011] An oil reservoir portion is formed at the center of the upper surface of the bottom plate of the heat insulating oil pan, extending downward and protruding.

[0012] A partition plate extending in the front-to-rear direction and projecting upward is formed in the center of the bottom surface of the main housing mounting space, with its front and rear ends connected to the front and rear inner wall surfaces of the mounting space. A downward-extending groove is formed in the center of the top surface of the partition plate, and sealant is fitted to the top surface of the partition plate, the front and rear side walls and the bottom surface of the groove. The wall plate of the oil reservoir is located within the groove, and the outer surfaces of the front and rear walls are in close contact with the corresponding side surfaces of the sealant, and the bottom surface of the bottom plate abuts against the top surface of the bottom sealant. The partition plate and oil reservoir separate the lower part of the mounting space into a left ventilation chamber and a right ventilation chamber.

A left ventilation fan 20 and a right ventilation fan 30 are installed on the lower left and right sides of the installation space, respectively, and multiple ventilation slits are formed in the bottom plate and lower side wall of the main housing 10 between the two fans.

[0026] Vertical plate sections 14 extending forward and backward are formed on the left and right sides of the top surface of the mounting space bottom plate, and a horizontal plate section extending horizontally outward is provided at the top of each vertical plate section 14. Side vertical partition plate sections 15 are formed at the corresponding left and right ends of the bottom plate, and the vertical plate sections 14, horizontal plate sections, side vertical partition plate sections 15, and corresponding positions on the bottom plate form the fan mounting space. The left ventilation fan 20 and the right ventilation fan 30 are placed in the corresponding fan mounting space, and their front and rear end plates are fixed to the front and rear wall surfaces of the fan mounting space. Attachment / detachment slits extending forward and backward are formed in the bottom plate directly below the fans, and a lower cover is fixed to the bottom plate, covering the slits. The fans can be attached and detached by opening the lower cover.

[0027] A right intake port is formed on the right side of the casing of the right ventilation fan 30, and a ventilation passage is formed between it and the inner wall of the right plate of the main housing 10. A right exhaust port is formed on the left side of the casing, which communicates with the right ventilation chamber at the bottom of the main housing 10. A left intake port is formed on the right side of the casing of the left ventilation fan 20, which communicates with the left ventilation chamber, and a left exhaust port is formed on the left side, which forms a ventilation passage between it and the inner wall of the left plate of the main housing 10.

[0028] The left vertical plate portion 14 is formed with a plurality of left ventilation slits, which communicate with the left intake port of the left ventilation fan 20 and the left ventilation chamber. The right vertical plate portion 14 is formed with a right ventilation slit, which communicates with the right outlet port of the right ventilation fan 30 and the right ventilation chamber.

[0029] An insulating oil pan 40 is attached to the upper part of the installation space of the main housing 10, and a plurality of ventilation holes 49 are formed in the upper parts of the left and right side plates thereof, which communicate with the corresponding ventilation passages. A heating tube 50 is placed on the upper surface of the bottom plate of the insulating oil pan 40, and a grill plate 60 is placed on the upper surface of the heating tube 50.

[0030] A control host 70 is fixed to the front of the heating tube 50 and is electrically connected to a control board (details omitted as it is of a conventional structure). The control host 70 is inserted into a central recess extending downward in the center of the upper surface of the front wall panel of the main housing 10, and the connection part with the heating tube 50 is inserted into a downward-extending recess in the upper center of the front wall panel of the heat-insulating oil pan 40. The front wall surface of the control host 70 does not protrude beyond the front end of the recess.

[0031] A positioning recess 11 extending downward is formed in the center of the bottom surface of the recess, and a positioning protrusion 71 extending downward is formed in the center of the bottom surface of the control host 70. The positioning protrusion 71 is inserted and fitted into the positioning recess 11, and multiple rear heat dissipation holes are formed in the rear wall surface of the recess 11. A longitudinal grip groove 72 extending rearward is formed in the center of the front wall of the control host 70, allowing attachment and detachment with one hand while maintaining the integrity of the housing exterior.

[0032] The inner wall of the top of the mounting space is formed with edge 12 extending radially outward, with protruding support parts provided at the front and rear of the left and right sides. The upper left and right side plates of the insulating oil pan 40 are formed with bent support edges 41 extending horizontally outward, which abut the upper surfaces of the corresponding protruding support parts. The center of the top surface of the bottom plate of the insulating oil pan 40 is formed with an oil reservoir 42 protruding downward.

[0033] A partition plate 13 extending forward and backward and protruding upward is formed in the center of the bottom surface of the mounting space of the main housing 10, with its front and rear ends connecting to the inner wall surfaces of the mounting space. A downward-extending groove is formed in the center of the top surface of the partition plate 13, and sealant is fitted to the top surface of the partition plate, the front and rear side walls, and the bottom surface of the groove. The wall plate of the oil reservoir 42 is located within the groove, with its front and rear outer wall surfaces in close contact with the sides of the corresponding sealant, and the bottom surface of the bottom plate abutting the top surface of the bottom sealant. The front and rear bottom surfaces of the bottom plate of the insulating oil tray 40 abut against the sealant on the top surface of the partition plate 13, and the partition plate 13 and oil reservoir 42 separate the lower part of the mounting space into left and right ventilation chambers, isolating the airflow paths of both fans.

[0034] A plurality of protruding support ribs 15 extending forward and backward are formed on the upper surface of the horizontal plate portion, and the bottom surface of the heat insulating oil pan 40 abuts against the upper surfaces of all the support ribs 15 .

[0035] One or more horizontal support rods 51 extend to the left and right and contact the bottom surface of the heating tube 50, with downward bent portions formed at both ends. The horizontal support rods 51 are fixed to the heating tube 50 by bent fixing brackets, and the ends of the bent portions contact the upper surface of the bottom plate of the insulating oil pan 40.

[0036] A protrusion 61 corresponding to the heating tube 50 is formed in the center of the bottom surface of the grill plate 60, and a recessed groove for fitting the heating tube 50 is provided on the bottom surface of this protrusion. The part corresponding to the heating tube 50 is inserted into the longitudinal groove, and its upper surface abuts on the upper surface of the groove. This increases the contact area and improves heating efficiency. Grips are fixed to the front and back of the top surface of the grill plate 60.

[0037] Leg pads are fixed to the front, rear, left and right ends of the bottom surface of the bottom plate of the main housing 10.

[0038] The left and right ventilation fans 20, 30 use cross-flow fans that extend forward and backward, achieving high flow rate and high wind pressure with the same power consumption, thereby saving energy.

[0039] The main body of the heat generating tube 50 is wound in an S-shape to ensure a sufficient heating length in a limited space.

[0040] During use, the right ventilation chamber is filled with filter cotton (not shown) to cover the outlet of the right ventilation fan 30. After connecting the cord to the power connector on the front of the control host 70, the left and right fans are started simultaneously. The left ventilation fan 20 draws in cool air from below the main housing 10 through the lower slit of the left ventilation chamber → left intake port → left outlet → left ventilation passage → and then sprays it out above the grill plate 60 from the ventilation hole 49. Smoke generated by heating is guided to the right, sucked in through the intake port of the right ventilation fan 30 → the oil smoke is removed by the filter cotton → and discharged through the lower slit of the right ventilation chamber. After use, the grill plate 60, heating tube 50, and insulating oil tray 40 can be removed and the filter cotton replaced.

[0041] The heating tube 50 and control host 70 are detachably mounted on the main housing 10, making maintenance easy. Dual ventilation using left and right fans maximizes smoke exhaust efficiency.

[0042] The heat-insulating oil pan 40 combines heat insulation and oil collection functions, and directs oil to the oil reservoir 42. This eliminates the need for a separate oil collection pan, reducing manufacturing costs.

[0043] The horizontal support rod 51 at the bottom of the heating tube 50 eliminates the need for a dedicated support stand.

[0044] As shown in Figure 8, the mounting space is divided into a left mounting space 71 and a right mounting space 72. The left mounting space 71 and the left ventilation fan 20 form a detachable mating connection, and the upper end is closed by a left connection cover 73. Similarly, the right side is closed by a right connection cover 74. The electrical connection ends of the left and right fans form mating connections with either the bottom, side, front or rear ends of each mounting space.

[0045] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art may make various modifications and variations within the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention, and the patentable scope of the present invention is limited by the claims.
