Description

Technical Field

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

[0002] Currently, cooking appliances on the market, such as pizza machines, only have one exhaust cooling or multiple air outlets for cooling, but this method is not effective and the temperature rise is still very high. In order to solve the problem of high shell temperature rise, some pizza machines even use insulation cotton for cooling. Although this method ensures cooling, it increases the cost. In addition, the insulation cotton will cause skin allergies after human body contact during the production process, resulting in itchy hands and even blisters on the operator's hands. Utility Model Content

[0003] The utility model provides a cooking utensil with secondary accelerated cooling, aiming to solve the problem that the heat dissipation and temperature reduction effect of the cooking utensil in the prior art is poor.

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

[0005] The utility model provides a cooking utensil with secondary accelerated cooling, comprising:

[0006] The housing comprises an inner housing and an outer housing, wherein a ventilation passage is formed between the outer housing and the inner housing; an air inlet and an air outlet are arranged on the outer housing, and both the air inlet and the air outlet are connected to the ventilation passage; a cooking cavity is arranged in the inner housing;

[0007] A control component located in the ventilation duct;

[0008] A cooling fan is located in the ventilation duct and is arranged close to the air inlet; the cooling fan is close to the control component;

[0009] The fan assembly is located in the ventilation duct and is arranged close to the air outlet; under the action of the fan assembly, cold air from the outside enters the ventilation duct through the air inlet and is discharged through the air outlet.

[0010] A further solution: the air inlet portion includes a top air inlet arranged at the front end of the top of the housing, a bottom air inlet arranged at the bottom of the housing, and side air inlets respectively arranged on the left and right walls of the housing;

[0011] The top air inlet, the bottom air inlet and the side air inlet are all connected to the ventilation duct.

[0012] Based on the above scheme, the positions of the top air inlet, bottom air inlet and side air inlet on the outer shell allow cold air from the outside to enter the ventilation duct through the top air inlet, bottom air inlet and side air inlet and be evenly distributed inside the cooking appliance, thereby cooling the interior of the cooking appliance in all directions and improving the heat dissipation effect of the cooking appliance.

[0013] A further solution: the air outlet portion includes an air outlet located at the rear end of the top of the shell; the air outlet is connected to the ventilation duct.

[0014] Based on the above scheme, the air outlet is used to discharge the hot air in the ventilation duct, and the air outlet and the air inlet composed of the top air inlet, the bottom air inlet and the side air inlet form a circulating ventilation system, so that the wind in the ventilation duct can flow, so that the cold air from the outside enters the ventilation duct to take away the heat and then is discharged, thereby realizing the heat dissipation of the cooking appliance.

[0015] A further solution: the housing includes a rear cover; the air outlet is arranged on the top of the rear cover;

[0016] The fan assembly includes an exhaust fan, which is arranged between the rear cover and the inner shell and is located below the air outlet; when the exhaust fan is working, the exhaust fan will take away the heat in the ventilation duct with the cold air entering the ventilation duct and then discharge it through the air outlet.

[0017] Based on the above solution, the exhaust fan can be used to guide the hot air in the ventilation duct to flow to the air outlet and exhaust it to the outside, which can accelerate the air circulation in the ventilation duct and improve the heat dissipation efficiency. In addition, the air outlet is arranged at the top of the rear cover plate, so that the cooking appliance discharges hot air upwards to avoid blowing directly to the user.

[0018] A further solution: the air inlet portion further includes a fan air inlet located at the bottom of the shell; the fan air inlet is connected to the ventilation duct.

[0019] A further solution: the fan air inlet is circular.

[0020] Based on the above solution, the fan air inlet is circular, corresponding to the shape of the heat dissipation fan, thereby improving the utilization rate of the cold air entering the ventilation duct from the fan air inlet.

[0021] A further solution: the cooling fan is arranged above the fan air inlet; under the action of the cooling fan, the cold air entering the ventilation duct through the fan air inlet takes away the heat generated by the control component to form hot air, and forms convection with the cold air in the ventilation duct.

[0022] Based on the above solution, the cooling fan allows the cold air entering the ventilation duct through the fan air inlet to take away the heat generated by the control component, thereby achieving local cooling of the cooking appliance. In addition, in the ventilation duct, convection causes the hot air and the cold air to mix, accelerating the cooling of the cooking appliance.

[0023] A further solution: the control component includes a power board and an IH coil disk.

[0024] A further solution: a support plate for supporting the cooling fan, the power board and the IH coil disk is provided above the bottom of the housing, and the support plate is located in the ventilation duct.

[0025] Based on the above scheme, the support plate can effectively fix and support the cooling fan, power board and IH coil disk, so that they can be arranged in an orderly manner inside the cooking utensil, making full use of the space and ensuring the stability and safety of the internal structure of the cooking utensil.

[0026] A further solution: a power board bracket is provided on the support plate, and the power board is arranged on the bracket of the power board.

[0027] The beneficial effects of the utility model are:

[0028] In the present invention, on the one hand, the cold air entering the ventilation duct through the air inlet cools down the control component under the action of the heat dissipation fan, takes away the heat generated by the control component, and realizes the primary heat dissipation and cooling of the cooking appliance. On the other hand, the cold air from the outside enters the ventilation duct through the air inlet and takes away the heat emitted from the cooking cavity into the ventilation duct, cools down the interior of the cooking appliance as a whole, and then is discharged through the air outlet under the drive of the fan component, thereby realizing the secondary heat dissipation and cooling of the cooking appliance. The secondary heat dissipation and cooling of the cooking appliance in the present invention enables the cooking appliance to be cooled quickly, and can avoid the problem of high temperature rise of the control component and the shell of the cooking appliance.
