[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0037] Please refer to Figure 1 as well as Fig.12A cooking appliance, comprising a shell 1, a frying basket 2, a baking tray assembly 3 and a fan assembly 4, wherein the shell 1 is provided with a cooking cavity 101 and an assembly cavity 102 which are connected to each other, the shell 1 is provided with an air vent 103 which is connected to the assembly cavity 102 and an opening 104 which is connected to the cooking cavity 101, the frying basket 2 is arranged in the cooking cavity 101 through the opening 104, and the baking tray assembly 3 is arranged on the top of the shell 1; the fan assembly 4 is arranged in the assembly cavity 102, and the fan assembly 4 is used to form an airflow flowing from the assembly cavity 102 to the air vent 103 and an airflow flowing from the assembly cavity 102 to the cooking cavity 101;

[0038] The shell 1 is also provided with a first channel 105, a second channel 106 and a third channel 107 which are respectively connected to the assembly cavity 102. The first channel 105 is arranged between the side wall of the cooking cavity 101 and the side wall of the shell 1, the second channel 106 is arranged at the bottom of the cooking cavity 101, and the third channel 107 is arranged at the top of the cooking cavity 101. The shell 1 is provided with a first air inlet hole 108, a second air inlet hole 109, and a third air inlet hole 110 which are respectively connected to the first channel 105, the second channel 106, and the third channel 107.

[0039] The working principle of the utility model is briefly described as follows: in actual application, the cooking utensil described in the utility model can fry food through the baking tray assembly 3, thereby realizing the function of the electric baking tray 304; the cooking utensil can also blow hot air from the assembly cavity 102 to the cooking cavity 101 through the fan assembly 4, and the hot air can quickly crisp the surface of the food, thereby locking the moisture inside the food, achieving a cooking effect of crispy outside and tender inside, and achieving a fried cooking taste without frying, thereby realizing the function of an air fryer.

[0040] The grill assembly 3 of the cooking utensil described in the utility model is arranged on the top of the housing 1, so the cooking utensil needs to occupy a small horizontal space when placed. Since the cooking utensil needs to form hot air circulation in the frying basket 2 in the cooking cavity 101 when using the air fryer function, it causes the cooking utensil to easily have the problem of over-temperature and has an adverse effect on the electrical components of the electric grill assembly 3. In order to solve this problem, the housing 1 of the cooking utensil is respectively provided with a first channel 105, a second channel 106 and a third channel 107 corresponding to the side wall, the bottom and the top of the cooking cavity 101, and the third channel 107 is specifically arranged between the top of the cooking cavity 101 and the bottom of the grill assembly 3, and the first channel 105, the second channel 106 and the third channel 107 are all connected to the assembly cavity 102. The fan assembly 4 of the cooking appliance can form an airflow that flows from the assembly cavity 102 to the vent 103, so that the assembly cavity 102 can generate a negative pressure effect, so that the air outside the shell 1 enters the first channel 105, the second channel 106, and the third channel 107 through the first air inlet hole 108, the second air inlet hole 109, and the third air inlet hole 110 respectively to form an airflow, and the airflow flowing in the first channel 105, the second channel 106, and the third channel 107 can take away the heat between the cooking cavity 101 and the shell 1 and the heat between the cooking cavity 101 and the baking tray assembly 3, and the airflow will converge to the assembly cavity 102, and finally, under the action of the fan assembly 4, the airflow will be discharged from the vent 103.

[0041] As can be seen from the above description, the beneficial effect of the utility model is that the fan assembly 4 of the cooking utensil provided by the utility model for realizing the air fryer function can generate airflow from the assembly cavity 102 to the vent hole 103 when working, so as to form a plurality of airflow channels arranged around the cooking cavity 101 through the first channel 105, the second channel 106 and the third channel 107, thereby improving the heat dissipation performance of the cooking utensil when using the air fryer function, and the cooking utensil can solve the problem that the electrical components of the baking tray assembly 3 cannot be quickly dissipated when using the air fryer function, and can prevent the shell 1 of the cooking utensil from softening and deforming under high temperature. Therefore, the cooking utensil has the advantages of high reliability and long service life.

[0042] Furthermore, the frying basket 2 includes a cover 201 for sealing the opening 104 , and the cover 201 is provided with a fourth channel 2011 along its height direction, and the fourth channel 2011 is respectively connected to the third air inlet 110 and the third channel 107 .

[0043] As can be seen from the above description, the surface cover 201 of the frying basket 2 of the cooking utensil is provided with a fourth channel 2011 which is respectively connected with the third air inlet hole and the third channel 107. During the heat dissipation process, the cooking utensil can form an airflow of: third air inlet hole-fourth channel 2011-third channel 107-assembly cavity 102-vent 103, wherein the airflow flows upward in the vertical direction when passing through the fourth channel 2011, and flows in the horizontal direction when passing through the third channel 107. The cooking utensil can also achieve excellent heat dissipation effect for its frying basket 2, thereby preventing the surface cover 201 of the frying basket 2 from softening and deforming due to excessive temperature. This can not only improve the service life of the frying basket 2 of the cooking utensil, but also reduce the risk of burns caused by the user accidentally touching the high-temperature frying basket 2 during use.

[0044] Furthermore, a chamfered portion 111 is provided between the opening 104 and the bottom of the housing 1 , and a plurality of the third air inlet holes 110 are evenly arranged on the chamfered portion 111 .

[0045] From the above description, it can be seen that, specifically, a plurality of third air inlet holes 110 are evenly opened in the width direction of the chamfered portion 111 of the shell 1, which can effectively improve the air flow rate and air flow uniformity in the third channel 107 and the fourth channel 2011, thereby further improving the heat dissipation capacity of the air flow in the third channel 107 and the fourth channel 2011.

[0046] Furthermore, the fan assembly 4 includes a driving member 401, a first fan blade 402, a second fan blade 403 and a heating tube 404 which are arranged in sequence along a direction close to the cooking chamber 101, and the first fan blade 402 and the second fan blade 403 are both arranged on a driving shaft 4011 of the driving member 401.

[0047] From the above description, it can be seen that the first fan blade 402 is used to form an airflow from the assembly cavity 102 to the vent 103, and the second fan blade 403 is used to form an airflow from the assembly cavity 102 to the cooking cavity 101, and the second fan blade 403 can bring the heat generated by the heating tube 404 to the cooking cavity 101 when rotating.

[0048] Furthermore, the fan assembly 4 also includes a first air guide cover 405 , wherein the first air guide cover 405 is disposed between the first fan blade 402 and the second fan blade 403 , and the driving shaft 4011 is disposed through the first air guide cover 405 .

[0049] Furthermore, the assembly cavity 102 is divided by the first air guide cover 405 to form a hot air chamber 1021 and a cold air chamber 1022. A first connecting hole 4051 connecting the hot air chamber 1021 and the cold air chamber 1022 is opened on the side wall of the first air guide cover 405. The hot air chamber 1021 is connected to the cooking cavity 101, and the first channel 105, the second channel 106 and the third channel 107 are all connected to the cold air chamber 1022.

[0050] As can be seen from the above description, the first air guide 405 can reduce the mutual influence between the first blade 402 and the second blade 403, and the first air guide 405 can connect the hot air chamber 1021 and the cold air chamber 1022 through the first connecting hole 4051, so that a part of the airflow entering the cold air chamber 1022 can flow into the hot air chamber 1021 by the negative pressure formed by the second blade 403, thereby forming a hot air flow through the second blade 403 and the heating tube 404 to enter the cooking cavity 101. In addition, in the cooking appliance, the first blade 402 and the second blade 403 are both driven by the driving member 401, that is, when the air fryer function of the cooking appliance is working, the hot air circulation and cold air heat dissipation functions are turned on at the same time, which makes the cooking appliance highly reliable and stable.

[0051] Furthermore, the fan assembly 4 also includes a guide duct 406 and a second wind guide cover 407, the second wind guide cover 407 is arranged between the driving member 401 and the first fan blade 402, and the second wind guide cover 407 is arranged on the first wind guide cover 405, the second wind guide cover 407 includes a cover plate 4071 and a side plate 4072, and there is a gap between the side plate 4072 and the side wall of the first wind guide cover 405 to form a ventilation flow channel 408, and a second connecting hole 4073 and a third connecting hole 4074 are opened on the cover plate 4071, and the two ends of the guide duct 406 are respectively connected to the ventilation hole 103 and the second connecting hole 4073.

[0052] From the above description, it can be seen that the guide duct 406 and the second air guide cover 407 can better guide the airflow in the cold air chamber 1022, and a third connecting hole 4074 is opened on the second air guide cover 407, so that the airflow can enter the second air guide cover 407 through the third connecting hole 4074.

[0053] Furthermore, the ratio between the diameter of the first blade 402 and the diameter of the second blade 403 is 1.1 to 1.2.

[0054] From the above description, it can be seen that setting the ratio between the diameter of the first fan blade 402 and the diameter of the second fan blade 403 to 1.1-1.2 can optimize the comprehensive working effect of the first fan blade 402 and the second fan blade 403.

[0055] Furthermore, the vent holes 103 are each provided with an air guide plate 1031 in the vertical direction. The air guide plate 1031 is arranged to be inclined upward in a direction away from the assembly cavity 102 , and an angle between the air guide plate 1031 and the horizontal direction is 30 to 60°.

[0056] From the above description, it can be seen that because the airflow that takes out the heat in the shell 1 will be blown out from the vent hole 103, the air guide plate 1031 can guide the airflow to avoid the airflow being blown out in the horizontal direction and causing safety hazards.

[0057] Furthermore, a plurality of the first air inlet holes 108 are evenly formed on the side wall of the housing 1 along its height direction, and the first air inlet holes 108 are arranged at a position of the side wall of the housing 1 away from the assembly cavity 102;

[0058] The bottom of the shell 1 is provided with supporting feet 112 , and the bottom of the shell 1 is evenly provided with a plurality of second air inlet holes 109 , and the second air inlet holes 109 are arranged at a position of the bottom of the shell 1 away from the assembly cavity 102 .

[0059] From the above description, it can be seen that the first air inlet hole 108, the second air inlet hole 109 and the third air inlet hole 110 are all opened at a position of the shell 1 away from the assembly cavity 102, so as to increase the flow distance of the gas in the first channel 105, the second channel 106 and the third channel 107 as much as possible, so as to make the heat dissipation effect of the cooking device better.
