Description

Technical Field

[0001] The present application relates to the technical field of kitchenware, and in particular to a cooking device with a baking function. Background Art

[0002] Cooking equipment such as ovens and steam ovens can use flowing hot air to bake food. In traditional technology, this type of cooking equipment has an inner pot, a baking tray, a heating tube, a hot air blower and a heat dissipation fan. The baking tray, the heating tube and the fan of the hot air blower are all located in the inner pot, and the food is placed on the baking tray. The heating tube is used to heat the air in the inner pot, the fan of the hot air blower is used to make the hot air in the inner pot flow, and the heat dissipation fan is used to dissipate heat from the cooking equipment. The hot air blower and the heat dissipation fan each have a drive motor for driving the fan to rotate, so this type of cooking equipment in traditional technology contains two drive motors, which is more power-consuming, not conducive to energy saving, and has a high cost of use. Moreover, some of this type of cooking equipment has added a drive motor for rotating the baking tray to improve the uniformity of heating of the food, which results in the cooking equipment containing three drive motors, making the cooking equipment more power-consuming, not conducive to energy saving, and further increasing the cost of use of the cooking equipment. Summary of the invention

[0003] Based on this, it is necessary to provide a cooking device with a grilling function to address the above problems.

[0004] In order to solve the above problems, the present application provides the following technical solutions:

[0005] A cooking device with a grilling function, the cooking device with a grilling function comprising:

[0006] Liner;

[0007] An air guide plate is located in the inner liner and together with the inner liner encloses a hot air chamber, and the air guide plate is provided with an air outlet;

[0008] A heating pipe is located in the hot air chamber;

[0009] A heat dissipation duct is fixedly arranged on the outside of the inner tank;

[0010] A fan, comprising a rotating shaft, an inner fan and an outer fan, wherein the rotating shaft passes through the inner liner, the inner fan and the outer fan are both fixed to the rotating shaft, the inner fan is located in the hot air chamber, and the outer fan is located in the heat dissipation duct;

[0011] A bottom support, arranged in the inner liner;

[0012] A plurality of balls, each of which is rollably disposed on the base;

[0013] A baking tray is arranged in the inner pot; the baking tray includes a tray body and a plurality of blades protruding from the tray body, the tray body is overlapped on the ball bearing and rotatably connected to the base, and the rotation axis of the tray body relative to the base is a first rotation axis; a portion of the tray body forms an annular area, the annular area is located in the direction of the air outlet and the center of the annular area is located on the first rotation axis, and a plurality of blades are distributed in the annular area in sequence; each of the blades at least partially faces the air outlet when located in the state of being located in the direction of the air outlet.

[0014] The cooking device with grilling function has at least the following beneficial effects:

[0015] In the cooking process of the cooking device, the heating tube heats the air in the inner pot, and the rotating shaft rotates, thereby driving the inner fan and the outer fan to rotate. When the inner fan rotates, the hot air in the inner pot flows, playing the role of a hot air blower in traditional technology. When the outer fan rotates, it continuously discharges the hot air in the heat dissipation duct and continuously introduces the cold air from the outside into the heat dissipation duct, playing the role of a heat dissipation fan in traditional technology.

[0016] During the operation of the cooking device, the hot air flow stirred by the internal fan flows from the air outlet to the annular area. After the hot air flow hits the part of the blade facing the air outlet, the blade is thrust in the circumferential direction, and the baking tray rotates relative to the base. Different blades continuously appear alternately in the direction of the air outlet, and the baking tray can rotate continuously. The setting of the ball bearing can reduce the friction between the baking tray and the base, which is conducive to ensuring the continuous rotation of the baking tray.

[0017] To sum up the above, the cooking device provided by the present application only uses one driving motor to simultaneously achieve the three functions of making the hot air in the inner pot flow, dissipating the heat of the cooking device and rotating the baking tray, while the cooking device in traditional technology needs three driving motors to achieve this. Therefore, the cooking device provided by the present application can reduce energy consumption, is beneficial to energy saving, and can reduce the use cost of the cooking equipment.

[0018] In one of the embodiments, the air guide plate is provided with a plurality of air outlets, and the circumferences of the air outlets are evenly distributed on the same circle with the center located on the circumference of the first rotating shaft, and there is at least one blade in the direction of each air outlet.

[0019] Such a setting is conducive to the uniform outflow of hot air from the air guide plate. On the one hand, this is conducive to uniform heating of food and improved cooking effect. On the other hand, this is conducive to the hot air flow flowing out of the air guide plate evenly hitting the baking tray, which is conducive to uniform force on the baking tray and smooth rotation of the baking tray.

[0020] In one embodiment, the blades are evenly distributed around the circumference.

[0021] Such an arrangement is conducive to the baking tray being evenly affected by the hot air flow and is conducive to the baking tray rotating smoothly.

[0022] In one embodiment, the hot air chamber is located at the upper part of the inner tank, the fan is arranged on the top wall of the inner tank, the inner fan faces directly downward, the air outlet faces directly downward, a plurality of vents are arranged on the annular area, each of the vents is evenly distributed around the circumference, and each of the vents penetrates the disk body in the vertical direction; the vents are arranged one by one in correspondence with the blades, each of the blades is convexly arranged on the bottom side of the disk body, each of the blades is spirally bent along the first rotating axis, and the orthographic projection of each blade on the disk body is located in the corresponding vent, and there is at least one vent in the direction of each air outlet.

[0023] With this arrangement, the hot air flow in the hot air chamber first flows downward to the area above the food, and then continues to flow downward to the area below the food through the ventilation holes, which is conducive to evenly heating the food and improving the cooking effect. After passing through the ventilation holes, the hot air flow hits the blades, thereby driving the baking tray to rotate.

[0024] In one of the embodiments, the air outlet is disposed on a portion of the air guide plate away from the first rotating shaft, and the vent and the blades are both disposed on a portion of the disk body away from the first rotating shaft.

[0025] With such arrangement, the distance between the force exerted by the hot air flow on the blade and the first rotating shaft is relatively large, and the torque exerted by the hot air flow on the baking tray is relatively large, which is conducive to the hot air flow pushing the baking tray to rotate.

[0026] In one embodiment, the disc body and the base together enclose an annular space adapted for the balls, the annular space is coaxially arranged with the annular area, and each of the balls is located in the annular space.

[0027] With such arrangement, each ball is restricted to roll in the annular space, and each ball has a clear rolling path, which can prevent the balls from rolling in a disorderly manner and facilitate the smooth rotation of the baking tray.

[0028] In one embodiment, the disk body includes a tray and a limiting member, the limiting member and the base together enclose the annular space, the limiting member overlaps the ball, and the tray overlaps the limiting member.

[0029] With such arrangement, the tray and the limiting member can be separated. When taking out food, only the tray needs to be taken out, and the limiting member remains in the original position, which can ensure that the ball bearings are always confined in the annular space.

[0030] In one embodiment, the portion of the limiting member relatively close to the first rotating shaft and the base together enclose an annular space, and the portion of the limiting member relatively far from the first rotating shaft and the base together enclose another annular space, and a plurality of the balls are arranged in each annular space.

[0031] With such arrangement, the balls in the two annular spaces jointly support the baking tray, which can improve the stability of the rotation of the baking tray.

[0032] In one embodiment, a portion of the outer side of the tray protrudes in a direction perpendicular to the first rotating axis to form a raised portion, and the limiting member is provided with a limiting hole that is conformally matched to the raised portion, and the raised portion is located in the limiting hole.

[0033] Such an arrangement can limit the position of the tray and prevent the tray from being displaced.

[0034] In one embodiment, the cooking equipment includes a grill and two racks, both of which are located in the inner pot. The two racks are arranged opposite to each other and are fixed to the inner pot. Each rack is provided with a limiting groove, and the limiting grooves on the two racks are aligned. The grill has a limiting rod, and the limiting groove is conformally adapted to the limiting rod. The grill overlaps the two racks and the limiting rod is located in the two limiting grooves; the grill is provided with a recessed space conformally adapted to the base, and the base is placed in the recessed space.

[0035] Such an arrangement can limit the position of the base and prevent the base from being displaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] See also Figures 1 to 10 The present application provides a cooking device with a baking function, which includes an inner pot 1, an air guide plate 2, a heating tube 4, a heat dissipation duct 5, a fan 6, a base 7, a plurality of ball bearings 8 and a baking tray 9.

[0055] See also Figure 3 The air guide plate 2 is located in the inner tank 1 and encloses a hot air chamber 3 together with the inner tank 1. The air guide plate 2 is provided with an air outlet 21. The heating pipe 4 is located in the hot air chamber 3, and the heat dissipation duct 5 is fixedly arranged outside the inner tank 1.

[0056] See also Figure 3 and Figure 5 The fan 6 includes a driving motor, an inner fan 62 and an outer fan 63. The driving motor includes a rotating shaft 61 for outputting a rotational motion, and the rotating shaft 61 is arranged in the inner pot 1. The inner fan 62 and the outer fan 63 are both fixedly arranged on the rotating shaft 61, the inner fan 62 is located in the hot air chamber 3, and the outer fan 63 is located in the heat dissipation duct 5. During the cooking process of the cooking device, the heating tube 4 heats the air in the inner pot 1, and the rotating shaft 61 rotates, thereby driving the inner fan 62 and the outer fan 63 to rotate. When the inner fan 62 rotates, the hot air in the inner pot 1 flows, playing the role of a hot air blower in the traditional technology. When the outer fan 63 rotates, it continuously discharges the hot air in the heat dissipation duct 5 and continuously introduces the cold air from the outside into the heat dissipation duct 5, playing the role of a heat dissipation fan in the traditional technology.

[0057] See also Figure 3 and Figure 7 The bottom bracket 7 is disposed in the inner container 1, and each ball 8 is rotatably disposed on the bottom bracket 7. Figure 1 , Figures 3 to 8 The baking tray 9 is arranged in the inner pot 1. The baking tray 9 includes a tray body 91 and a plurality of blades 92 protruding from the tray body 91. The tray body 91 overlaps the ball bearing 8 and is rotatably connected to the bottom bracket 7. The rotation axis of the tray body 91 relative to the bottom bracket 7 is the first rotation axis 61. A portion of the tray body 91 forms an annular area 911. The annular area 911 is located in the direction of the air outlet 21 and the center of the annular area 911 is located on the first rotation axis 61. The plurality of blades 92 are sequentially spaced and distributed in the annular area 911. Each blade 92 at least partially faces the air outlet 21 when it is located in the state of facing the air outlet 21 upward. During the operation of the cooking device, the hot air flow stirred by the internal fan 62 flows from the air outlet 21 toward the annular area 911. After the hot air flow hits the portion of the blade 92 facing the air outlet 21, the blade 92 is subjected to a thrust in the circumferential direction, and the baking tray 9 rotates relative to the bottom bracket 7. Different blades 92 continuously and alternately appear in the direction of the air outlet 21, and the baking tray 9 can rotate continuously. The provision of the ball bearings 8 can reduce the friction between the baking tray 9 and the base 7, which helps to ensure that the baking tray 9 continues to rotate.

[0058] To sum up the above, the cooking device provided by the present application only uses one driving motor to simultaneously achieve the three functions of making the hot air in the inner pot 1 flow, dissipating the heat of the cooking device and rotating the baking tray 9, while the cooking device in the traditional technology needs three driving motors to achieve this. Therefore, the cooking device provided by the present application can reduce energy consumption, is beneficial to energy saving, and can reduce the use cost of the cooking equipment.

[0059] Exemplarily, the cooking device is a steamer or a steam oven.
