Description

Technical Field

[0001] This utility model relates to the field of food baking equipment, and in particular to an air intake structure for a grill. Background Technology

[0002] A grill is a kitchen appliance that uses electrical energy to bake food. It consists of a casing with a control board on it. A baking cavity is located in the center of the casing, containing a baking tray with heating elements on its upper and lower sides. During baking, food is placed in the tray, and the heating elements are activated to heat the tray and bake the food. However, existing grills often experience high temperatures from the heating elements during baking, which can easily transfer to non-working areas. This excessive heat in non-working areas can negatively impact the casing and internal components, particularly the control board. High temperatures in these areas can accelerate the aging of electronic components, degrade electrical performance, and reduce system stability, significantly impacting the lifespan of the appliance. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes an air intake structure for a grill, comprising a housing, an air inlet located at the bottom of the housing, an air intake channel, and a fan located within the air intake channel. A grilling tray is mounted on the housing, and the fan is positioned above the grilling tray.

[0004] In one embodiment, the housing includes a base, a left support arm, a right support arm, and an upper support arm. The air inlet is located at the lower end of the base, the air inlet channel is located inside the base, the left support arm, and the upper support arm, the fan is disposed on the upper support arm, and an air outlet is provided on the lower side of the upper support arm.

[0005] In one embodiment, a computer board is provided inside the left support arm.

[0006] In one embodiment, a baffle plate is provided on the side of the upper arm near the right arm.

[0007] In one embodiment, the upper support arm is provided with a first heat insulation cover and a second heat insulation cover, and the fan can blow air into the space between the first heat insulation cover and the second heat insulation cover, forming an air duct between the first heat insulation cover and the second heat insulation cover, and the air is discharged downward in a ring.

[0008] In one embodiment, a baffle plate is provided on the second heat insulation cover below the fan, and the baffle plate is bowl-shaped.

[0009] In one embodiment, the first heat insulation cover and the second heat insulation cover are square in shape, the wind baffle is also square, and the height of the wind baffle is half the distance between the first heat insulation cover and the second heat insulation cover.

[0010] The beneficial effects of this invention are as follows: Air is drawn in from the bottom of the casing, passes through the air inlet channel, and is blown out under the guidance of the air guide assembly. Because the air passes over the surface of the computer board, it can reduce the internal temperature of the computer board, thereby improving its service life. Furthermore, since the blown air enters the non-working area of ​​the baking cavity, it can isolate the heat radiation from the upper heating element from the upper part of the casing, preventing adverse effects on the casing and computer board due to excessive temperature, thus improving safety and service life. Attached Figure Description

[0011] Figure 1 This is a perspective view of the present utility model; Figure 2 This is a perspective view of the present utility model; Figure 3 The present invention provides an internal structure for a grill; Figure 4 A cross-sectional view provided for this utility model.

[0012] In the diagram, the components are: housing 1, base 11, left support arm 12, right support arm 13, upper support arm 14, air outlet 141, baffle plate 142, first heat insulation cover 15, second heat insulation cover 16, wind baffle plate 17, computer board 2, air inlet 3, air inlet channel 4, fan 5, baking tray 6, upper heating tube 71, and lower heating tube 72. Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figures 1 to 4 The disclosed air intake structure of a grill includes a housing 1, an air inlet 3 disposed at the bottom of the housing 1, an air intake channel 4, and a fan 5 disposed within the air intake channel 4. A baking tray 6 is disposed on the housing 1, and the fan 5 is located above the baking tray 6.

[0015] It is understandable that by setting up fan 5, air can circulate inside the housing 1, and cool air enters the housing 1 from the bottom and blows out from the top, which can reduce the temperature of the housing and prevent the heat of the baking pan 6 from spreading to the housing 1, thus protecting the housing 1.

[0016] Preferably, the housing 1 includes a base 11, a left support arm 12, a right support arm 13, and an upper support arm 14. The air inlet 3 is located at the lower end of the base 11, the air inlet channel 4 is located within the base 11, left support arm 12, and upper support arm 14, the fan 5 is disposed on the upper support arm 14, and an air outlet 141 is provided on the lower side of the upper support arm 14. Figure 4 In the image, arrows indicate the direction of airflow.

[0017] Preferably, a computer board 2 is provided inside the left support arm 12.

[0018] It is understandable that the left support arm 12 is an area where cold air circulates, making the temperature of the left support arm 12 relatively low. Placing the computer board 2 inside the left support arm 12 can provide better protection for the computer board 2.

[0019] Preferably, a baffle plate 142 is provided inside the upper support arm 14 on the side near the right support arm 13.

[0020] It is understood that the housing 1 has a left support arm 12 and a right support arm 13. When the top fan 5 is started, the air flows only from the left support arm 12 because a baffle plate 142 is provided on the right support arm 13 side, which makes the air flow faster and the cooling effect better.

[0021] Preferably, the upper support arm 14 is provided with a first heat insulation cover 15 and a second heat insulation cover 16. The fan 5 can blow air into the space between the first heat insulation cover 15 and the second heat insulation cover 16, forming an air duct between the first heat insulation cover 15 and the second heat insulation cover 16, and the air is discharged downward in a ring shape.

[0022] It is worth mentioning that by setting up a ring-shaped air outlet, the heating area can be isolated from the housing 1, thereby protecting the housing 1.

[0023] It should be noted that the first heat insulation cover 15 and the second heat insulation cover 16 have a double-layer heat insulation effect and can also guide the air, allowing the air to flow to the sides of the baking pan instead of directly onto the baking pan. This setting will not affect the frying or baking of the food in the baking pan.

[0024] Preferably, a baffle plate 17 is provided on the second heat insulation cover 16 below the fan 5, and the baffle plate 17 is bowl-shaped.

[0025] Preferably, the first heat insulation cover 15 and the second heat insulation cover 16 are square in shape, the wind baffle 17 is also square, and the height of the wind baffle 17 is half the distance between the first heat insulation cover 15 and the second heat insulation cover 16.

[0026] It is understandable that by giving the wind deflector 17 a certain height, the gap between the wind deflector 17 and the first heat insulation cover 15 is smaller, forming a high-pressure area in the middle, and the air entering through the fan 5 can flow out more evenly between the wind deflector 17 and the first heat insulation cover 15.

[0027] Combination Figure 4 As shown, the grill has an upper heating element 71 and a lower heating element 72. The upper heating element 71 is located below the second heat insulation cover 16, and the lower heating element 72 is located below the baking pan 6.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
