Description

Technical Field

[0001] The utility model belongs to the technical field of cooking utensils, and in particular relates to a cooking utensil with circulation heating. Background Art

[0002] Some cooking appliances on the market (such as ovens and pizza makers) use a top-down heating method, but there is no air convection in the cooking cavity, which causes the temperature in the cooking cavity to be uneven within a short period of time. This in turn causes the temperature in some parts of the cooking cavity to be too high, and the baked food may be partially burnt; or, the food may be partially cooked while other parts are still half-cooked and inedible. Utility Model Content

[0003] The utility model provides a cooking utensil with circulating heating, aiming to solve the problem in the prior art that uneven temperature distribution in a cooking cavity leads to poor heating effect on food.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The utility model provides a circulating heating cooking appliance, comprising:

[0006] A cooking cavity is provided with an air inlet and an air outlet; a heater is provided on at least one side of the cooking cavity;

[0007] A circulation cavity is located outside the cooking cavity; the circulation cavity is connected to the cooking cavity through the air inlet and the air outlet respectively;

[0008] A fan is located in the circulation cavity; under the action of the fan, the hot air in the cooking cavity enters the circulation cavity through the air outlet, and the hot air in the circulation cavity enters the cooking cavity through the air inlet.

[0009] A further solution: the air outlet is circular and is provided with an air outlet net.

[0010] Based on the above solution, the air outlet net can prevent oil stains or other impurities in the cooking cavity from entering the circulation cavity, so that the circulation cavity can be kept clean. In addition, the air outlet net can also help to evenly disperse the air, avoiding the occurrence of excessive wind speed and high temperature at the air outlet.

[0011] A further solution: the air inlet is in the shape of a strip, square, arc or circle.

[0012] A further solution is that: the heater is provided with one; one heater is arranged above the cooking cavity; or one heater is arranged below the cooking cavity.

[0015] There are two air inlets, which are arranged on the rear side wall of the inner pot and are respectively located on the left and right sides of the air outlet.

[0016] Based on the above scheme, the two air inlets are respectively arranged on the left and right sides of the air outlet. On the one hand, the air intake rate from the circulation cavity into the cooking cavity is increased; on the other hand, since the fan is close to the air outlet, when the fan rotates, the hot air in the circulation cavity is blown to both sides, thereby allowing the hot air to enter the cooking cavity through the air inlets on both sides.

[0017] A further solution: a deflector is provided on the outside of the rear side wall of the inner pot, and the circulation cavity is arranged between the rear side wall of the inner pot and the deflector; the air outlet and the air inlet are both located in the circulation cavity.

[0018] Based on the above solution, the deflector separates the circulation cavity from other spaces inside the cooking appliance, preventing the circulating hot air from flowing to other places and reducing the utilization rate of the hot air.

[0019] A further solution is that a fan mounting portion is provided in the middle of the air deflector; air guide channels are provided on opposite sides of the air deflector, and the hot air in the circulation cavity flows along the air guide channels to the corresponding air inlets.

[0020] Based on the above solution, the fan mounting portion enables the fan to be stably mounted in the circulation chamber.

[0021] A further solution: the fan blades are arranged toward the air outlet; the fan is driven by a drive motor, the drive motor is arranged outside the air duct, and the output shaft of the drive motor passes through the air duct and is connected to the fan.

[0022] Based on the above solution, the fan blades are arranged toward the air outlet, which can effectively push the hot air in the cooking cavity to flow into the circulation cavity through the air outlet, thereby improving the efficiency of the hot air circulation flow.

[0023] The beneficial effects of the utility model are:

[0024] The utility model is designed with a cooking cavity and a circulation cavity which are interconnected through the air inlet and the air outlet, and the fan is arranged in the circulation cavity near the air outlet, so that under the action of the rotation of the fan, the hot air in the cooking cavity enters the circulation cavity through the air outlet, and the hot air in the circulation cavity enters the cooking cavity through the air inlet, thereby allowing the hot air to circulate in the cooking cavity, and also allowing the cooking cavity to achieve uniform distribution of hot air in a short time, and evenly heat the food, thereby preventing the food from being partially burnt or undercooked.

[0025] In the present invention, on the one hand, the food is heated by the heater, and on the other hand, the heat that is not absorbed by the food and is lost in the cooking cavity is circulated, so that the excess heat can also act on the food to heat the food; the heating efficiency of the present invention is improved, and cooking time can be saved.
