The electric heating tube is powered to heat the grilling pan. The shell is arranged outside the grilling pan to play a role of heat insulation. However, since the grilling temperature of the grilling device is generally above 200 degrees Celsius, the heat insulation effect of a single shell is poor. In the prior art, some grills are provided with a fan inside the shell to conduct heat from the inside of the shell. However, since the fan generates noise and lowers the temperature of the grilling pan, the grilling effect is poor. Under some other schemes, additional insulation components are added, which will cause the entire product to become thicker, and a lot of insulation materials will be added, which will increase the cost and increase the production hours.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Certain directional terms used to describe the drawings below, such as "inside", "outside", "above", "below" and other directional terms, will be understood to have their normal meanings and refer to those directions involved when the drawings are normally viewed. Unless otherwise specified, the directional terms described in this specification are basically in accordance with the conventional directions understood by those skilled in the art.

[0023] The terms "first", "first", "second", "second" and the like used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0024] See also Figure 1-Figure 3 A grilling device includes a base 1, two grilling units 2, and a circulating airflow heat dissipation mechanism 3. One grilling unit 2 is arranged on the base 1, and the other grilling unit 2 is connected to the circulating airflow heat dissipation mechanism 3. The two grilling units 2 are pivotally connected so that the two grilling units 2 can be arranged to rotate and open with each other. The two grilling units 2 can be divided into an upper grilling unit and a lower grilling unit, and the upper grilling unit is arranged on the lower grilling unit to rotate and open.

[0025] The circulating airflow heat dissipation mechanism 3 forms a spacing air layer 31, the inner side 311 of the spacing air layer 31 is connected to the temperature rising part of the grill (i.e., the upper grilling unit), and the spacing air layer 31 includes two spaced-apart air passages 313, one of which is used for air intake, and the other of which is used for air discharge; the spacing air layer 31 absorbs the heat of the temperature rising part of the grill by means of heat radiation to form air convection between the two air passages 313. The air convection can take away the heat of the temperature rising part, thereby achieving the effect of heat dissipation.

[0026] The upper grilling unit includes the temperature riser, and the circulating airflow heat dissipation mechanism includes a shell 32 and a heat insulating member 33. The spaced air layer 31 is formed between the shell 32 and the heat insulating member 33. The side of the heat insulating member 33 facing away from the shell 32 is connected to the temperature riser. The heat insulating member 33 is spaced and locked to the inner side of the shell 32, and the temperature riser is spaced and locked to the inner side of the heat insulating member 33. The shell 32 is covered outside the heat insulating member 33 to prevent burns caused by direct contact with the heat insulating member 33.

[0027] The temperature rising component includes a grilling pan 21 and a heating tube 22 for heating the grilling pan 21; the grilling unit 2 also includes a heat insulating board 23 covered outside the heating tube 22; the inner side 311 of the spacing air layer 31 (i.e., the heat insulating component) is spaced apart from the heat insulating board 23 by a distance.

[0028] The air layer 31 has an airway opening 313 on the left and right sides of the slightly enclosed space. The air convection between the airway openings 313 forms an air insulation layer, and the gas in the insulation layer is always in a convection state, which can prevent the heat of the radiant heat zone below that gradually rises due to the heating of the heating pipe 22 from spreading to the top cover.

[0029] In this embodiment, the outer side 312 of the spacer air layer 31 forms the outer side cover of the grill, and the spacer air layer 31 can also function as a heat insulation layer. The spacer air layer 31 includes a middle portion 314 and a peripheral portion 315, the middle portion 314 has the same thickness, and the peripheral portion 315 is arranged around the temperature riser of the grill; the two airway openings 313 are arranged on the upper side of the peripheral portion 315. The peripheral portion 315 can prevent the user from directly contacting the peripheral area of ​​the temperature riser, and achieve a better heat insulation effect.

[0030] Among them, due to being close to the heating tube 22, the temperature of the middle part 314 increases faster than that of the peripheral part 315, causing the spacer air layer 31 to generate heat exchange from the middle to the periphery, thereby reducing the temperature of the middle part 314. However, if the grill is used for a long time or continuously, the exchange efficiency of the spacer air layer 31 will still decrease due to thermal balance. Therefore, in this embodiment, the thickness ratio of the middle part 314 to the peripheral part 315 is 1:3 or more, such as 1:3, 1:4, 1:5, etc., so as to increase the volume of the peripheral part 315 in a limited structure, increase its heat capacity, and delay the thermal balance time of the spacer air layer 31.

[0031] In this embodiment, the two air passage openings 313 are arranged on opposite sides of the grill, so that the airflow path is longer and more heat can be taken away.

[0032] The circulating airflow heat dissipation mechanism 3 includes a shell 32 and a heat insulating member 33. The heat insulating member 33 is arranged outside the temperature rising member of the grill. The shell 32 is arranged on the upper side of the heat insulating member 33. The spacer air layer 31 is formed between the shell 32 and the heat insulating member 33. The airway opening 313 is formed between the shell 32 and the heat insulating member 33.

[0033] In this embodiment, the upper side of the airway opening 313 further includes a shielding eaves plate extending outward, and the shielding eaves plate is used to shield the upper side of the airway opening, and the shielding eaves plate plays a role in guiding airflow.

[0034] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
