[0001] The utility model relates to the technical field of cooking equipment, in particular to a cooking equipment. Background Art

[0002] As the hot air function of ovens matures, more and more ovens have added hot air circulation functions. However, the hot air component will increase the size of the cooking equipment, causing inconvenience to the user's storage and use. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, the utility model proposes a cooking device, including: a cooking body, the cooking body has a cooking cavity, the cavity wall of the cooking cavity is provided with an air inlet and an air outlet, the air inlet and the air outlet are both connected to the cooking cavity, the cooking cavity includes a first cavity wall, the first cavity wall is provided with a first recessed portion, the first recessed portion protrudes the first cavity wall into the cooking cavity; an air guide cover, connected to the first cavity wall, the air guide cover is provided with a second recessed portion, an air guide cavity is formed between the air guide cover and the first cavity wall, the air inlet and the air outlet are both connected to the air guide cavity; a first fan blade, located in the air guide cavity, the first fan blade is accommodated in the first recessed portion, and the second recessed portion is arranged opposite to the first fan blade; a heat insulation pad, accommodated in the second recessed portion; a motor assembly, connected to the air guide cover, the output shaft of the motor assembly is connected to the first fan blade, the heat insulation pad is located between the motor assembly and the air guide cover, and at least a portion of the motor assembly is accommodated in the second recessed portion.

[0005] The air guide hood is installed on the first cavity wall, and the space between the air guide hood and the first cavity wall serves as the air guide cavity. The first fan blade is located in the air guide cavity. Driven by the motor assembly, the first fan blade can rotate in the air guide cavity. The first fan blade can blow the airflow from the air outlet to the cooking cavity. The gas in the cooking cavity flows into the air guide cavity from the air inlet. During the rotation of the first fan blade, a circulating airflow is formed between the air guide cavity and the cooking cavity, which is beneficial to improving the uniformity of temperature distribution in the cooking cavity.

[0006] A first recessed portion is provided on the first cavity wall, the first recessed portion protrudes toward the inside of the cooking cavity, and the first recessed portion provides installation space for the first blade, so that the first blade does not need to be higher than the first cavity wall, or only part of the first blade is higher than the first cavity wall. A second recessed portion is provided on the air guide cover, and the second recessed portion is directly opposite to the first blade. Since at least a part of the first blade is accommodated in the first recessed portion, space is provided for arranging the second recessed portion on the air guide cover, and the second recessed portion will not interfere with the first blade. When the motor assembly is installed, at least a part of the motor assembly is accommodated in the second recessed portion, so the motor assembly is not higher than the air guide cover, or only part of the motor assembly is higher than the air guide cover, reducing the space occupied by the motor assembly in the first direction, where the first direction refers to the axial direction of the motor assembly. In the case of adding the motor assembly and the first blade as the hot air assembly, the hot air assembly will not increase the size of the cooking device too much, thereby avoiding inconvenience for the user's storage and use.

[0007] A thermal insulation pad is provided in the second recessed portion. The thermal insulation pad is located between the motor assembly and the air guide cover. The thermal insulation pad insulates the motor assembly. When the first fan blade drives the air flow to circulate, the temperature in the air guide cavity will gradually increase. The thermal insulation pad has thermal insulation properties to prevent the heat in the air guide cavity from being transferred to the motor assembly, thereby avoiding the motor assembly from being affected by high temperature and ensuring the operating stability of the motor assembly.

[0008] In addition, the cooking device in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In some technical solutions, optionally, a third recess is provided on the thermal insulation pad, and at least a portion of the motor assembly is accommodated in the third recess.

[0010] A third recess is formed on the thermal insulation pad, and the third recess provides an installation space for the motor assembly. When a part of the motor assembly is accommodated in the third recess, the size occupied by the motor assembly along the first direction is further reduced, and the motor assembly can be closer to the first cavity wall, thereby further reducing the overall size of the cooking device, providing convenience for users to use the cooking device.

[0011] In some technical solutions, optionally, the motor assembly includes: a motor connected to the wind guide cover; a second fan blade connected to the motor, and the motor is used to drive the first fan blade and the second fan blade to rotate.

[0012] The motor is mounted on the air guide cover, and the first fan blade and the second fan blade are both connected to the output shaft of the motor. When the motor is running, the motor can drive the first fan blade and the second fan blade to rotate. When the second fan blade rotates, it can drive the air flow around the motor. The second fan blade is used as a heat dissipation fan blade to achieve heat dissipation of the motor, further reduce the impact of heat on the motor, and improve the running stability of the motor.

[0013] In some technical solutions, optionally, at least a portion of the second blade is accommodated in the third recessed portion.

[0014] A portion of the motor assembly is opposite to the third recessed portion, and at least a portion of the second fan blade is accommodated in the third recessed portion. The third recessed portion provides an installation space for the second fan blade. When a portion of the second fan blade is accommodated in the third recessed portion, the size occupied by the motor along the first direction is reduced, and the motor can be arranged close to the first cavity wall, thereby further reducing the overall size of the cooking device and providing convenience for the user to use the cooking device.

[0015] In some technical solutions, optionally, a portion of the second blade extends out of the third recess.

[0016] A portion of the second fan blade is located in the third recessed portion, and another portion of the second fan blade extends out of the third recessed portion. When the second fan blade rotates, it drives the surrounding airflow to flow. By extending a portion of the second fan blade out of the third recessed portion, the influence of the third recessed portion on the flow of airflow around the second fan blade is reduced, thereby ensuring the heat dissipation effect of the second fan blade on the motor.

[0017] In some technical solutions, optionally, a sub-recess is provided on the bottom wall of the second recess, and at least a portion of the thermal insulation pad is accommodated in the sub-recess.

[0018] A recessed structure, i.e., a sub-recessed portion, is formed on the bottom wall of the second recessed portion, and the sub-recessed portion is protruding toward the first fan blade. The sub-recessed portion provides space for installing the heat insulating pad, so that the heat insulating pad can be closer to the first cavity wall, and the motor assembly is located on one side of the heat insulating pad, so the motor assembly can also be closer to the first cavity wall, thereby further reducing the size occupied by the motor along the first direction, thereby further reducing the overall size of the cooking device, and providing convenience for users to use the cooking device.

[0019] In some technical solutions, optionally, the thermal insulation pad includes: a thermal insulation part, the thermal insulation part is located between the motor and the air guide cover, and the thermal insulation part is overlapped on the bottom wall of the second recessed part; a third recessed part, connected to the thermal insulation part, and the thermal insulation part is distributed along the circumference of the third recessed part.

[0020] The heat insulation portion is annular and is distributed around the third recessed portion. The third recessed portion is used to accommodate the second fan blade, and the heat insulation portion is located between the bottom wall of the second recessed portion and a portion of the motor. The heat insulation portion insulates the installation position of the motor to prevent the heat in the air guide cavity from being transferred to the motor. The design of the insulation pad can not only provide installation space for the second fan blade, but also effectively play a heat insulation role.

[0021] In some technical solutions, optionally, the first cavity wall includes a cavity top wall.

[0022] When the first cavity wall is the cavity top wall, the first fan blade and the motor assembly are installed above the cavity top wall. Since the first recessed portion is provided on the cavity top wall and the second recessed portion is provided on the air guide cover, the space occupied by the motor assembly and the first fan blade in the height direction can be reduced, thereby avoiding inconvenience to the user in placing and storing the cooking equipment.

[0023] In some technical solutions, optionally, the thickness W of the thermal insulation pad satisfies 3mm≤W≤5mm.

[0024] If the thickness of the thermal insulation pad is too small, the thermal insulation performance of the thermal insulation pad cannot be guaranteed, resulting in the thermal insulation pad being unable to effectively insulate the motor. If the thickness of the thermal insulation pad is too large, the thermal insulation pad will occupy too much space in the first direction, thereby excessively increasing the overall size of the cooking equipment. When the thickness of the thermal insulation pad is within the above range, it can not only play an effective insulating role, but also will not occupy too much space in the first direction. While ensuring that the overall size of the cooking equipment does not change much, the operating stability of the motor is guaranteed.

[0025] In some technical solutions, optionally, the thermal insulation pad includes at least one of the following: bakelite thermal insulation pad, silicone thermal insulation pad, mica thermal insulation pad, thermal insulation cotton and polybutylene terephthalate thermal insulation pad.

[0026] Insulation pads can not only be made of bakelite, but can also be made of silicone, mica sheets, plastic materials such as PBT (polybutylene terephthalate insulation pads), insulation cotton and many other materials.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0037] Refer to the following Figures 1 to 4 The cooking device provided according to some embodiments of the present invention is described.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in an embodiment of the utility model, a cooking device is proposed, including: a cooking body 100, an air guide cover 200, a first fan blade 300, a heat insulation pad 400 and a motor assembly 500. The cooking body 100 has a cooking cavity 110, and an air inlet 120 and an air outlet 130 are provided on the cavity wall of the cooking cavity 110. The air inlet 120 and the air outlet 130 are both connected to the cooking cavity 110. The cooking cavity 110 includes a first cavity wall 111, and a first recessed portion 112 is provided on the first cavity wall 111. The first recessed portion 112 protrudes from the first cavity wall 111 into the cooking cavity 110. The air guide cover 200 is connected to the first cavity wall 111, and a second recessed portion 210 is provided on the air guide cover 200. An air guide cavity 220 is formed between the air guide cover 200 and the first cavity wall 111, and the air inlet 120 and the air outlet 130 are both connected to the air guide cavity 220. The first fan blade 300 is located in the air guide cavity 220, the first fan blade 300 is accommodated in the first recessed portion 112, and the second recessed portion 210 is arranged opposite to the first fan blade 300. The heat insulation pad 400 is accommodated in the second recessed portion 210, the motor assembly 500 is connected to the air guide cover 200, the output shaft of the motor assembly 500 is connected to the first fan blade 300, the heat insulation pad 400 is located between the motor assembly 500 and the air guide cover 200, and at least a part of the motor assembly 500 is accommodated in the second recessed portion 210.

[0039] The air guide hood 200 is installed on the first cavity wall 111, and the space between the air guide hood 200 and the first cavity wall 111 serves as the air guide cavity 220. The first fan blade 300 is located in the air guide cavity 220. Driven by the motor assembly 500, the first fan blade 300 can rotate in the air guide cavity 220. The first fan blade 300 can blow the airflow from the air outlet 130 into the cooking cavity 110. The gas in the cooking cavity 110 flows into the air guide cavity 220 from the air inlet 120. During the rotation of the first fan blade 300, a circulating airflow is formed between the air guide cavity 220 and the cooking cavity 110, which is beneficial to improving the uniformity of temperature distribution in the cooking cavity 110.

[0040] A first recessed portion 112 is provided on the first cavity wall 111, and the first recessed portion 112 protrudes into the cooking cavity 110. The first recessed portion 112 provides installation space for the first blade 300, so that the first blade 300 does not need to be higher than the first cavity wall 111, or only a portion of the first blade 300 is higher than the first cavity wall 111. A second recessed portion 210 is provided on the air guide cover 200, and the second recessed portion 210 is directly opposite to the first blade 300. Since at least a portion of the first blade 300 is accommodated in the first recessed portion 112, space is provided for the second recessed portion 210 on the air guide cover 200, and the second recessed portion 210 will not interfere with the first blade 300. When the motor assembly 500 is installed, at least a portion of the motor assembly 500 is accommodated in the second recessed portion 210, so that the motor assembly 500 is not higher than the air scoop 200, or only a portion of the motor assembly 500 is higher than the air scoop 200, which reduces the motor assembly 500 in the first direction ( Figure 2 The arrow at b in the figure indicates the occupied space in the first direction), where the first direction refers to the axial direction of the motor assembly 500. When the motor assembly 500 and the first fan blade 300 are added as the hot air assembly, the hot air assembly will not increase the size of the cooking device too much, thereby avoiding inconvenience for the user in storage and use.

[0041] A thermal insulation pad 400 is provided in the second recessed portion 210. The thermal insulation pad 400 is located between the motor assembly 500 and the air guide cover 200. The thermal insulation pad 400 provides thermal insulation for the motor assembly 500. When the first fan blade 300 drives the air flow to circulate, the temperature in the air guide cavity 220 will gradually increase. The thermal insulation pad 400 has thermal insulation performance, which prevents the heat in the air guide cavity 220 from being transferred to the motor assembly 500, thereby avoiding the motor assembly 500 from being affected by high temperature and ensuring the operating stability of the motor assembly 500.

[0042] It should be noted that Figure 1 The air inlet 120 and the air outlet 130 can interchange functions, with the air inlet 120 being used as an opening for air outlet and the air outlet 130 being used as an opening for air intake.

[0043] In a possible application, the cooking device further includes a heating element 600 , which is installed in the cooking cavity 110 .

[0044] Combination Figure 1 and Figure 4 As shown, in some embodiments, optionally, a third recessed portion 410 is provided on the thermal insulation pad 400 , and at least a portion of the motor assembly 500 is accommodated in the third recessed portion 410 .

[0045] A third recess 410 is formed on the thermal insulation pad 400, and the third recess 410 provides an installation space for the motor assembly 500. When a portion of the motor assembly 500 is accommodated in the third recess 410, the size occupied by the motor assembly 500 along the first direction is further reduced, and the motor assembly 500 can be closer to the first cavity wall 111, thereby further reducing the overall size of the cooking device, providing convenience for users to use the cooking device.

[0046] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the motor assembly 500 includes: a motor 510 and a second fan blade 520, the motor 510 is connected to the wind guide cover 200, the second fan blade 520 is connected to the motor 510, and the motor 510 is used to drive the first fan blade 300 and the second fan blade 520 to rotate.

[0047] The motor 510 is mounted on the air guide cover 200, and the first blade 300 and the second blade 520 are both connected to the output shaft of the motor 510. When the motor 510 is running, the motor 510 can drive the first blade 300 and the second blade 520 to rotate. When the second blade 520 rotates, it can drive the airflow around the motor 510. The second blade 520 is used as a heat dissipation blade, which can achieve heat dissipation of the motor 510, further reduce the influence of heat on the motor 510, and improve the operation stability of the motor 510.

[0048] The wind direction of the second fan blade 520 can be designed not only to blow air toward the motor 510 , but also to blow air in the opposite direction of the motor 510 to absorb the heat around the motor 510 .

[0049] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, at least a portion of the second blade 520 is accommodated in the third recess 410 .

[0050] A portion of the motor assembly 500 is opposite to the third recessed portion 410, and at least a portion of the second fan blade 520 is accommodated in the third recessed portion 410. The third recessed portion 410 provides an installation space for the second fan blade 520. When a portion of the second fan blade 520 is accommodated in the third recessed portion 410, the size occupied by the motor 510 along the first direction is reduced. The motor 510 can be arranged close to the first cavity wall 111, thereby further reducing the overall size of the cooking device and providing convenience for the user to use the cooking device.

[0051] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, a portion of the second blade 520 extends out of the third recess 410 .

[0052] A portion of the second fan blade 520 is located in the third recessed portion 410, and another portion of the second fan blade 520 extends out of the third recessed portion 410. When the second fan blade 520 rotates, it drives the surrounding airflow to flow. By extending a portion of the second fan blade 520 out of the third recessed portion 410, the influence of the third recessed portion 410 on the flow of airflow around the second fan blade 520 is reduced, thereby ensuring the heat dissipation effect of the second fan blade 520 on the motor 510.

[0053] like Figure 4 As shown, in some embodiments, optionally, a sub-recess 230 is provided on the bottom wall of the second recess 210 , and at least a portion of the thermal insulation pad 400 is accommodated in the sub-recess 230 .

[0054] A recessed structure, i.e., a sub-recessed portion 230, is formed on the bottom wall of the second recessed portion 210, and the sub-recessed portion 230 is protruded toward the first fan blade 300. The sub-recessed portion 230 provides space for the installation of the heat insulating pad 400, and the heat insulating pad 400 can be closer to the first cavity wall 111. The motor assembly 500 is located on one side of the heat insulating pad 400, so the motor assembly 500 can also be closer to the first cavity wall 111, thereby further reducing the occupied size of the motor 510 along the first direction, thereby further reducing the overall size of the cooking device, and providing convenience for users to use the cooking device.

[0055] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, the thermal insulation pad 400 includes: a thermal insulation portion 420, the thermal insulation portion 420 is located between the motor 510 and the air guide cover 200, and the thermal insulation portion 420 is overlapped on the bottom wall of the second recessed portion 210; a third recessed portion 410, connected to the thermal insulation portion 420, and the thermal insulation portion 420 is distributed along the circumference of the third recessed portion 410.

[0056] The heat insulation part 420 is annular, and the heat insulation part 420 is distributed around the third recessed part 410. The third recessed part 410 is used to accommodate the second fan blade 520, and the heat insulation part 420 is located between the bottom wall of the second recessed part 210 and a portion of the motor 510. The heat insulation part 420 insulates the installation position of the motor 510 to prevent the heat in the air guide cavity 220 from being transferred to the motor 510. The design of the heat insulation pad 400 can not only provide an installation space for the second fan blade 520, but also effectively play a heat insulation role.

[0057] In some embodiments, optionally, the first cavity wall 111 includes a cavity top wall.

[0058] When the first cavity wall 111 is the cavity top wall, the first fan blade 300 and the motor assembly 500 are installed above the cavity top wall. Since the first recessed portion 112 is provided on the cavity top wall and the second recessed portion 210 is provided on the air guide cover 200, the space occupied by the motor assembly 500 and the first fan blade 300 in the height direction can be reduced, thereby avoiding inconvenience to the user in placing and storing the cooking equipment.

[0059] In some embodiments, optionally, the thickness of the thermal insulation pad 400 ( Figure 4 The arrow at a points to the thickness direction of the thermal insulation pad 400 , W satisfies, 3mm≤W≤5mm.

[0060] If the thickness of the thermal insulation pad 400 is too small, the thermal insulation performance of the thermal insulation pad 400 cannot be guaranteed, resulting in the thermal insulation pad 400 being unable to effectively insulate the motor 510. If the thickness of the thermal insulation pad 400 is too large, the thermal insulation pad 400 will occupy too much space in the first direction, thereby excessively increasing the overall size of the cooking device. When the thickness of the thermal insulation pad 400 is within the above range, it can not only play an effective thermal insulation role, but also will not occupy too much space in the first direction. While ensuring that the overall size of the cooking device does not change much, the operating stability of the motor 510 is guaranteed.

[0061] Exemplarily, the thickness of the thermal insulation pad 400 is 3 mm, 4 mm or 5 mm.

[0062] In some embodiments, the thermal insulation pad 400 may include at least one of the following: a bakelite thermal insulation pad, a silicone thermal insulation pad, a mica thermal insulation pad, thermal insulation cotton, and a polybutylene terephthalate thermal insulation pad.

[0063] The thermal insulation pad 400 can be made not only of bakelite, but also of more materials such as silicone, mica sheets, plastic materials such as PBT (polybutylene terephthalate thermal insulation pad), thermal insulation cotton, etc.

[0064] Exemplarily, the cooking device may be an oven. The following solution only takes an oven with a top hot air function as an example and is applicable to all hot air ovens.

[0065] In the recessed space where the motor 510 is installed in the air guide cover 200, an electric thermal insulation pad (thermal insulation pad 400) is designed between the hot air motor 510 and the air guide cover 200 in the shape of the recessed shape of the air guide cover 200. The thermal insulation pad 400 is 3 mm thick and blocks heat from rising from the bottom to the motor 510.

[0066] A small fan blade (second fan blade 520 ) is designed on the rotor of the motor 510 and installed on the heat insulation pad 400 . The second fan blade 520 can blow air toward the motor 510 to dissipate the heat that has reached the motor 510 .

[0067] The designs of the above two parts can effectively delay the temperature rise of the motor 510, and the design of the heat dissipation solution only increases the height of the motor 510 by 3 mm, which can effectively achieve heat dissipation in a compact hot air system space.

[0068] The utility model mainly solves the problem that the existing structural solution meets the temperature rise requirement of motor 510, but brings about complex installation, increased weight and increased cost. The optimized structural solution design is adopted, with fewer parts and lower cost, to improve the temperature rise ability of existing products, reduce the cost of existing products, and the design can also be considered for subsequent development of new products to improve product competitiveness.
