[0002] Cooking equipment with baking function (oven, steam-bake combination machine, etc.) is equipped with heating tubes on the top, bottom and back of the inner pot, and uses radiant heat to heat the food placed in the inner pot. Furthermore, in order to observe the baking state of the food, a lighting lamp is generally arranged on the inner pot, and the lighting lamp is used to illuminate the inside of the inner pot. In order to reduce the influence of the heat generated by the heating tube on the lighting lamp, the lighting lamp is generally arranged on the left and right sides of the inner pot. However, the lighting effect is poor, and the illumination range of the lighting lamp cannot completely cover the entire food area.

[0003] For this reason, some cooking equipment sets the lighting lamp on the top of the inner pot, and the lighting lamp has a wide range of illumination and good lighting effect. For example, the Chinese utility model patent with patent number ZL201821853779.1 (authorization announcement number CN209269437U) discloses a steam oven, including a box body and an inner pot, a water tank and a steam generating device are arranged between the box body and the inner pot, and a lighting assembly is fixedly installed on the top wall of the inner pot, and the lighting assembly includes a light-transmitting plate, a lamp and a lampshade. However, since a heating tube is arranged on the top of the inner pot, if the lamp is installed on the top of the inner pot, the high temperature environment will cause its temperature to rise higher, thereby affecting its service life.

In addition, an upper illuminating port 110 and a lower illuminating port 100 are respectively provided on the upper mounting plate 11 and the top wall of the inner pot 10, so that the illuminating light emitted by the illuminating lamp 4 can be injected from the top of the inner pot 10 to illuminate the food placed in the inner pot 10, and an upper light-transmitting plate 5 is sealed on the upper illuminating port 110, and a heat-insulating lower light-transmitting plate 6 is sealed on the lower illuminating port 100, and the upper illuminating port 110 and the lower illuminating port 100 are connected through the heat-insulating sleeve 7 arranged in the first gap 12, so that a closed illuminating channel is formed between the upper illuminating port 110 and the lower illuminating port 100, so as to minimize the heat radiated to the illuminating lamp 4, and to better reduce the heat radiated from the inner pot 10 to the illuminating lamp 4 while ensuring the lighting effect of the illuminating lamp 4.

[0039] Furthermore, the cross-sectional size of the air guide plate 14 decreases from the back to the front, so that the airflow in the heat dissipation channel 140 can be accelerated, and the heat dissipation effect of the heat dissipation channel 140 can be improved, and the top wall of the air guide plate 14 is inclined downward from the back to the front.

[0040] Furthermore, the heat insulating sleeve 7 is a vertically extending cylinder, which is sandwiched between the lower surface of the upper mounting plate 11 and the outer top surface of the inner liner 10, and the upper end of the heat insulating sleeve 7 is circumferentially arranged outside the upper lighting port 110 and the lower end is circumferentially arranged outside the lower lighting port 100, and the upper end of the heat insulating sleeve 7 is fixed to the upper mounting plate 11 by a fastener 75 and / or the lower end is fixed to the top of the inner liner 10 by a fastener 75. Thus, the heat insulating sleeve 7 can be firmly connected between the upper lighting port 110 and the lower lighting port 100, and a closed lighting channel can be formed between the upper lighting port 110 and the lower lighting port 100. In this embodiment, the material of the heat insulating sleeve 7 is high temperature resistant plastic.

[0041] Furthermore, the upper light-transmitting plate 5 and the lower light-transmitting plate 6 are both circular in shape, wherein the upper light-transmitting plate 5 is arranged on the upper lighting port 110 from bottom to top, and the lower light-transmitting plate 6 is arranged on the lower lighting port 100 from top to bottom. The upper port of the above-mentioned heat-insulating sleeve 7 is formed with an upper ring step 71 for the upper light-transmitting plate 5 to be embedded, and the lower port is formed with a lower ring step 72 for the lower light-transmitting plate 6 to be embedded, so that the upper light-transmitting plate 5 can be firmly sealed on the upper lighting port 110, and the lower light-transmitting plate 6 can be firmly sealed on the lower lighting port 100.

The front ends of the upper plate body 831 and the lower plate body 833 are respectively bent downward along their own length directions and fixed to the inner surface of the outer door panel 81, while the rear ends of the upper plate body 831 and the lower plate body 833 are respectively fixed along the length directions through the vertically extending middle plate body 832, and the middle plate body 832 is bent forward along the middle part of its height direction and placed on the upper end part of the inner door panel 82, so that the upper bracket 83 can be firmly set in the upper vent 801.

[0046] In addition, preferably, the lower lighting port 100 and the top heating tube 13 are staggered, so as to reduce the amount of heat generated by the top heating tube 13 radiated to the lower lighting port 100.
