In order to solve the problem that the pot cover is thick in the cooking utensil in the prior art, the utility model provides a baking cover and cooking utensil.

As shown in fig. 1 to 17, the toasting cover comprises a heating element 7 and a main body part, the main body part is provided with a heating space 4, a heat dissipation space 21 and an air inlet cavity, the heating element 7 is positioned in the heating space 4, the air inlet cavity is communicated with the heating space 4 and the heat dissipation space 21, the main body part is provided with a first air outlet 22 communicated with the heating space 4 and a second air outlet 23 communicated with the heat dissipation space 21, and the heat in the heating space 4 flows out of the heating space 4 through the first air outlet 22; the air in the heat dissipation space 21 flows out of the heat dissipation space 21 through the second air outlet 23.

The heating element 7 on the baking cover 1 provides heat required for baking for the cooking appliance, and the air inlet chamber is communicated with the heating space 4 and the heat dissipation space 21, so that air blown out from the air inlet chamber can simultaneously flow into the heating space 4 and the heat dissipation space 21 to take away the heat in the heating space 4 and the heat dissipation space 21. The air inlet chamber blows heat in the heating space 4 into the pot body 3 through the first air outlet 22 to heat food in the pot body 3. And the air inlet chamber blows in the outside of toasting lid 1 with the heat in the heat dissipation space 21 through second air outlet 23 to reduce the heat of toasting lid 1, reduce and toast the device on the lid 1 and be heated and damage, increased and toasted stability and the security that lid 1 used, make cooking utensil's temperature rise accord with the safety regulation requirement. Meanwhile, the temperature of the baking cover 1 is reduced, the baking cover 1 can be prevented from accidentally injuring a user, and the use safety of the baking cover 1 is improved. One air inlet chamber blows air to the heating space 4 and the heat dissipation space 21 simultaneously, so that the use of fans can be reduced, the baking cover 1 is thinner, and the miniaturization of the baking cover 1 is facilitated.

Example one

Specifically, the heating space 4 and the heat dissipation space 21 are independent from each other. Set up like this and can avoid the phenomenon of mixing of gases between heating space 4 and the heat dissipation space 21, avoid the high-temperature gas in the heating space 4 to enter into the heat dissipation space 21, reduced the high temperature to toasting the toasting of the device on the lid 1, reduced the fault rate of toasting the lid 1, increased stability and the security of toasting the use of lid 1. The heating space 4 and the heat dissipation space 21 are independent from each other, which means that the gas introduced into the heating space 4 and the gas introduced into the heat dissipation space 21 do not communicate with each other. Or, the heating space 4 and the heat dissipation space 21 are independent from each other, that is, the air in the two spaces does not interfere with each other, the air in the air inlet chamber directly flows out of the baking cover 1 after entering the heat dissipation space 21, and does not flow into the heating space 4, and the air in the air inlet chamber directly flows out of the baking cover 1 after entering the heating space 4, and does not flow into the heat dissipation space 21.

As shown in fig. 3 to 6, the main body has a first air inlet 24 communicating with the heating space 4 and a second air inlet 25 communicating with the heat dissipating space 21, and the air inlet chamber can supply air to the first air inlet 24 and the second air inlet 25 at the same time. By arranging the first air inlet 24 and the second air inlet 25 on the main body part, air blown out from the air inlet cavity can simultaneously supply air to the first air inlet 24 and the second air inlet 25, so as to simultaneously blow air to the heating space 4 and the heat dissipation space 21, thereby reducing the temperature of the baking cover 1 and enabling the baking cover 1 to stably work.

Specifically, the area of the first air inlet 24 is larger than that of the second air inlet 25. Set up like this and make the gas that blows into in heating space 4 be more than the gas that blows into in heat dissipation space 21 to guarantee to carry out abundant heat transfer to heating element 7 in heating space 4, and then blow into pot body 3 with the heat that heating element 7 produced fast, toast the food in the pot body 3. Because heating element 7 sets up in heating space 4, heating space 4's heat is far greater than heat dissipation space 21, sends into the gas that heats space 4 and also is more than the gas in heat dissipation space 21, can blow out the heat that heating element 7 produced fast like this and toast lid 1 to guarantee to toast the temperature that lid 1 can not too high, can also guarantee to toast efficiency.

Specifically, the ratio of the area of the second air inlet 25 to the area of the first air inlet 24 is greater than or equal to 0.2 and less than or equal to 0.3. The ratio of the area of the second air inlet 25 to the area of the first air inlet 24 is smaller than 0.2, so that the area of the second air inlet 25 is too small, and the air entering the heat dissipation space 21 is less, which results in poor heat dissipation effect of the top of the baking cover 1 and does not achieve sufficient heat dissipation effect of the top of the baking cover 1. If the ratio of the area of the second air inlet 25 to the area of the first air inlet 24 is greater than 0.3, the airflow entering the heating space 4 is relatively small, so that the heat generated by the heating element 7 cannot be sent out to the outside of the baking cover 1 in time, the temperature of the baking cover 1 is easily increased, and the baking efficiency of the baking cover 1 is also low.

As shown in fig. 5, the first air inlet 24 is disposed on the side wall of the heating space 4 to realize lateral air supply; and/or the second air inlet 25 is provided on the side wall of the heat dissipation space 21 to realize the side air supply. The first air inlet 24 is disposed on the side wall of the heating space 4, so that the air inlet chamber and the heating element 7 are not overlapped in the gravity direction, and the thickness of the baking cover 1 can be reduced, so that the baking cover 1 is more light and thin. The second air inlet 25 is disposed on the side wall of the heat dissipation space 21, so that the air inlet cavity and the heat dissipation space 21 are not overlapped in the gravity direction, and the thickness of the baking cover 1 can be reduced, so that the baking cover 1 is more light and thin.

Optionally, the heating space 4 has a first ventilation flow channel, the first air outlet 22 is located at the end of the first ventilation flow channel, and the first air inlet 24 is located at the beginning of the first ventilation flow channel, so that the wind entering from the first air inlet 24 can pass through all positions of the heating element 7 along the first ventilation flow channel. The arrangement is such that the air entering the heating space 4 through the first air inlet 24 does not directly flow out of the heating space 4 through the first air outlet 22, so as to ensure that the gas flowing into the heating space 4 can fully exchange heat with the heating element 7 and then flows out of the heating space 4, and further the baking gas has a certain temperature, so as to increase the baking efficiency.

Optionally, the heat dissipation space 21 has a second ventilation flow channel, the second air outlet 23 is located at the end of the second ventilation flow channel, and the second air inlet 25 is located at the beginning of the second ventilation flow channel. The arrangement is such that the air entering the heat dissipation space 21 through the second air inlet 25 does not directly flow out of the heat dissipation space 21 through the second air outlet 23, so as to ensure that the air flowing into the heat dissipation space 21 can take away the heat in the heat dissipation space 21, thereby reducing the temperature of the baking cover 1.

As shown in fig. 3 to 6 and 9 to 12, the bottom of the heating space 4 has a baffle plate 8. The baffle 8 seals the bottom of the heating space 4, so that the gas blown into the heating space 4 only flows out of the heating space 4 from the first air outlet 22 and does not flow out from other places, and the user can be prevented from being scalded by the high-temperature gas. Meanwhile, the baffle 8 can reduce the oil stain gas in the pot body 3 from entering the heating space 4, and reduce the oil stain attached to the heating element 7. Because the baffle 8 is not connected with the electric device, the oil stain is attached to the baffle 8 to facilitate cleaning, and the surface of the baffle 8 can be cleaned by wiping with a wet rag.

The upper reflector 13 reflects heat generated by the heating element 7 downward to reduce the temperature transmitted to the cover assembly 11, the sidewall of the lower reflector 14 has a first air inlet 24 and a first air outlet 22, and the first air inlet 24 and the first air outlet 22 are located at two symmetrical sides of the heating space 4, so that the distance between the first air inlet 24 and the first air outlet 22 is the farthest, and wind flowing into the heating space 4 through the air inlet cavity can be blown out from the first air outlet 22 after exchanging heat with the heating element 7 sufficiently, so that the temperature of the blown wind is higher, and the baking efficiency is increased.

As shown in fig. 11 and 12, the reflector assembly 12 further includes a baffle 8, and the baffle 8 is attached to the bottom of the lower reflector 14 to block the heating space 4. The arrangement is such that the wind blown into the heating space 4 can sufficiently exchange heat with the heating element 7 and then flow out of the heating space 4 to increase the baking efficiency.
