Description
Technical Field
[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 having a cooking cavity, an air inlet and an air outlet are provided on the cavity wall of the cooking cavity, and the air inlet and the air outlet are both connected to the cooking cavity; an air guide cover, connected to the cavity wall of the cooking cavity, an air guide cavity is formed between the air guide cover and the cavity wall of the cooking cavity, the air inlet and the air outlet are both connected to the air guide cavity, and a first recess is provided on the air guide cover; fan blades are located in the air guide cavity, and the first recess is arranged opposite to the fan blades; a motor assembly is connected to the air guide cover, the output shaft of the motor assembly is connected to the fan blades, and at least a portion of the motor assembly is accommodated in the first recess.
[0005] The air guide hood is installed on the cavity wall of the cooking cavity, and the space between the air guide hood and the cavity wall serves as the air guide cavity. The fan blades are located in the air guide cavity. Driven by the motor assembly, the fan blades can rotate in the air guide cavity. The fan blades can blow the airflow from the air outlet into the cooking cavity, and the gas in the cooking cavity flows into the air guide cavity from the air inlet. During the rotation of the fan blades, 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] When the motor assembly is installed, at least a portion of the motor assembly is accommodated in the first recessed portion, so that the motor assembly is not higher than the air guide cover, or only a portion of the motor assembly is higher than the air guide cover, thereby 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. When the motor assembly and the fan blades 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.
[0007] When the motor assembly is accommodated in the first recessed portion, the air guide cover can protect the motor assembly, making it difficult for the motor assembly to collide with other components. As a result, there is no need to provide a separate protective plate for the motor assembly, saving the space occupied by the protective plate, which is conducive to further reducing the overall size of the cooking equipment.
[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, the cooking cavity includes a first cavity wall, a second recessed portion is provided on the first cavity wall, the second recessed portion protrudes out of the first cavity wall into the cooking cavity, and the fan blade is located in the second recessed portion.
[0010] A second recessed portion is provided on the first cavity wall, the second recessed portion protrudes toward the inside of the cooking cavity, and the second recessed portion provides installation space for the fan blades, so that the fan blades do not need to be higher than the first cavity wall, or only part of the fan blades are higher than the first cavity wall. In this way, the space occupied by the motor assembly in the first direction is further reduced, thereby further reducing the overall size of the cooking device.
[0011] In some technical solutions, optionally, the second recessed portion and the first cavity wall are integrally provided; or the second recessed portion is detachably connected to the first cavity wall, and the air guide cover is connected to the second recessed portion.
[0012] The second recessed portion and the first cavity wall can be formed into an integrated structure by stamping the plate. The second recessed portion and the first cavity wall can also be separated into different structures. In this case, the second recessed portion and the air guide cover can be assembled into an assembly, and then the assembly can be installed on the top plate of the whole machine.
[0013] In some technical schemes, optionally, the motor assembly includes a motor body and an output shaft, the output shaft extends out of the motor body, and along the axial direction of the motor assembly, the length of the motor body is L1, and the distance between the bottom wall of the first recessed portion and the side of the air guide cover facing away from the cooking body is L2, and L1 and L2 satisfy that L2≥0.5L1.
[0014] In order to ensure that the first recess can effectively accommodate the motor assembly, it is necessary to ensure that the first recess has sufficient depth, and the depth of the first recess is limited to be greater than or equal to half the axial length of the motor body, so that at least half of the structure of the motor body along the axial direction can be accommodated in the first recess, which can not only reduce the space occupied by the motor assembly, but also enable the first recess to effectively protect the motor assembly.
[0015] In some technical solutions, optionally, L1 and L2 satisfy, L2≤0.8L1.
[0016] If the depth of the first recessed portion is too large, the thickness of the air guide cover corresponding to the first recessed portion will be too thin, or the first recessed portion needs to be arranged to protrude toward the cooking cavity.
[0017] When the thickness of the air guide cover corresponding to the first recessed portion is relatively thin, it is difficult for the air guide cover to stably support the motor assembly. When the first recessed portion is arranged to protrude toward the cooking cavity, the space occupied by the air guide cover along the first direction will increase. Therefore, it is necessary to limit the depth of the first recessed portion. When L1 and L2 satisfy L2≤0.8L1, the above problem can be effectively avoided.
[0018] In some technical solutions, optionally, the first cavity wall includes a cavity top wall.
[0019] When the first cavity wall is the cavity top wall, the fan blades and the motor assembly are installed above the cavity top wall. Since the second recess is provided on the cavity top wall and the first recess is provided on the air guide cover, the space occupied by the motor assembly and the fan blades in the height direction can be reduced, thereby avoiding inconvenience to the user in placing and storing the cooking equipment.
[0020] In some technical solutions, optionally, one of the air inlet and the air outlet is arranged on the first cavity wall, and the other of the air inlet and the air outlet is arranged on the second recessed portion.
[0021] According to the type of fan blades, the air guide cavity is determined to have a central air intake or a surrounding air intake, so that the air inlet can be set on the first cavity wall or the second recessed portion according to the air intake method.
[0022] In some technical solutions, optionally, the air guide hood includes a galvanized air guide hood and / or a polybutylene terephthalate air guide hood.
[0023] The material of the air guide cover can be galvanized sheet or PBT (polybutylene terephthalate air guide cover).
[0024] In some technical solutions, optionally, the circumferential side of the motor assembly is spaced apart from the side wall of the first recessed portion.
[0025] A gap is left between the motor assembly and the side wall of the first recessed portion, and the gap provides a heat dissipation space for the motor assembly, so that the motor assembly can dissipate heat stably, thereby ensuring the operational stability of the motor assembly.
[0026] In some technical solutions, optionally, the cooking device includes any one of the following: an oven, a steam oven, and a microwave oven and steamer.
[0027] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. 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.
[0035] 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.
[0036] Refer to the following Figures 1 to 3 The cooking device provided according to some embodiments of the present invention is described.
[0037] Combination Figure 1 , Figure 2 and Figure 3As shown, in an embodiment of the utility model, a cooking device is proposed, including: a cooking body 100, an air guide cover 200, a fan blade 300 and a motor assembly 400. 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, and the air inlet 120 and the air outlet 130 are both connected to the cooking cavity 110. The air guide cover 200 is connected to the cavity wall of the cooking cavity 110, and an air guide cavity 210 is formed between the air guide cover 200 and the cavity wall of the cooking cavity 110, and the air inlet 120 and the air outlet 130 are both connected to the air guide cavity 210, and a first recessed portion 220 is provided on the air guide cover 200. The fan blade 300 is located in the wind guide cavity 210, the first recessed portion 220 is arranged opposite to the fan blade 300, the motor assembly 400 is connected to the wind guide cover 200, the output shaft 420 of the motor assembly 400 is connected to the fan blade 300, and at least a portion of the motor assembly 400 is accommodated in the first recessed portion 220.
[0038] The air guide hood 200 is installed on the cavity wall of the cooking cavity 110, and the space between the air guide hood 200 and the cavity wall serves as the air guide cavity 210. The fan blades 300 are located in the air guide cavity 210. Driven by the motor assembly 400, the fan blades 300 can rotate in the air guide cavity 210. The fan blades 300 can blow the airflow from the air outlet 130 into the cooking cavity 110, and the gas in the cooking cavity 110 flows into the air guide cavity 210 from the air inlet 120. During the rotation of the fan blades 300, a circulating airflow is formed between the air guide cavity 210 and the cooking cavity 110, which is beneficial to improving the uniformity of temperature distribution in the cooking cavity 110.
[0039] When the motor assembly 400 is installed, at least a portion of the motor assembly 400 is accommodated in the first recessed portion 220, so that the motor assembly 400 is not higher than the air guide cover 200, or only a portion of the motor assembly 400 is higher than the air guide cover 200, thereby reducing the space occupied by the motor assembly 400 in the first direction, where the first direction refers to the axial direction of the motor assembly 400 ( Figure 2 The arrow at the middle mark a points to the axial direction of the motor assembly 400). When the motor assembly 400 and the 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.
[0040] When the motor assembly 400 is accommodated in the first recessed portion 220, the air guide cover 200 can protect the motor assembly 400, making it difficult for the motor assembly 400 to collide with other components. As a result, there is no need to provide a separate protective plate for the motor assembly 400, thus saving the space occupied by the protective plate and helping to further reduce the overall size of the cooking equipment.
[0041] In some embodiments, optionally, the cooking cavity 110 includes a first cavity wall 140 , a second recessed portion 150 is provided on the first cavity wall 140 , the second recessed portion 150 protrudes out of the first cavity wall 140 into the cooking cavity 110 , and the fan blade 300 is located in the second recessed portion 150 .
[0042] A second recessed portion 150 is provided on the first cavity wall 140, and the second recessed portion 150 protrudes toward the inside of the cooking cavity 110. The second recessed portion 150 provides installation space for the fan blades 300, so that the fan blades 300 do not need to be higher than the first cavity wall 140, or only part of the fan blades 300 is higher than the first cavity wall 140. In this way, the space occupied by the motor assembly 400 in the first direction is further reduced, thereby further reducing the overall size of the cooking device.
[0043] In some embodiments, optionally, the second recessed portion 150 and the first cavity wall 140 are integrally provided; or the second recessed portion 150 is detachably connected to the first cavity wall 140 , and the air guide cover 200 is connected to the second recessed portion 150 .
[0044] The second recessed portion 150 and the first cavity wall 140 can be formed into an integrated structure by stamping the plate. The second recessed portion 150 and the first cavity wall 140 can also be separated into different structures. In this case, the second recessed portion 150 and the air guide cover 200 can be assembled into an assembly, and then the assembly can be installed on the top plate of the whole machine.
[0045] In some embodiments, optionally, the motor assembly 400 includes a motor body 410 and an output shaft 420, the output shaft 420 extends out of the motor body 410, and along the axial direction of the motor assembly 400, the length of the motor body 410 is L1, and the distance between the bottom wall of the first recessed portion 220 and the side of the air guide cover 200 facing away from the cooking body 100 is L2, and L1 and L2 satisfy that L2 ≥ 0.5L1.
[0046] In order to ensure that the first recessed portion 220 can effectively accommodate the motor assembly 400, it is necessary to ensure that the first recessed portion 220 has a sufficient depth, and the depth of the first recessed portion 220 is limited to be greater than or equal to half the axial length of the motor body 410, so that at least half of the structure of the motor body 410 along the axial direction can be accommodated in the first recessed portion 220, which can not only reduce the space occupied by the motor assembly 400, but also enable the first recessed portion 220 to effectively protect the motor assembly 400.
[0047] Exemplarily, L1 is 13.8 mm. L3 is the distance between the bottom of the second recessed portion 150 and the top of the motor body 410. Exemplarily, L3 is 34.8 mm.
[0048] In some embodiments, optionally, L1 and L2 satisfy, L2≤0.8L1.
[0049] If the depth of the first recessed portion 220 is too large, the thickness of the air guide cover 200 corresponding to the first recessed portion 220 will be too thin, or the first recessed portion 220 needs to be protruded toward the cooking cavity 110 .
[0050] When the thickness of the air ductor 200 corresponding to the position of the first recessed portion 220 is relatively thin, it is difficult for the air ductor 200 to stably support the motor assembly 400. When the first recessed portion 220 is disposed protruding toward the cooking cavity 110, the space occupied by the air ductor 200 along the first direction will increase. Therefore, it is necessary to limit the depth of the first recessed portion 220. When L1 and L2 satisfy L2≤0.8L1, the above problem can be effectively avoided.
[0051] In some embodiments, optionally, the first cavity wall 140 includes a cavity top wall.
[0052] When the first cavity wall 140 is the cavity top wall, the fan blades 300 and the motor assembly 400 are installed above the cavity top wall. Since the second recess 150 is provided on the cavity top wall and the first recess 220 is provided on the air guide cover 200, the space occupied by the motor assembly 400 and the fan blades 300 in the height direction can be reduced, thereby avoiding inconvenience to the user in placing and storing the cooking equipment.
[0053] In some embodiments, optionally, one of the air inlet 120 and the air outlet 130 is disposed on the first cavity wall 140 , and the other of the air inlet 120 and the air outlet 130 is disposed on the second recessed portion 150 .
[0054] According to the type of the fan blade 300 , the air guide cavity 210 is determined to have central air intake or all-around air intake, so that the air inlet 120 can be set on the first cavity wall 140 or the second recessed portion 150 according to the air intake method.
[0055] In some embodiments, optionally, the air scoop 200 includes a galvanized air scoop and / or a polybutylene terephthalate air scoop.
[0056] The material of the air guide cover 200 can be galvanized sheet or PBT (polybutylene terephthalate).
[0057] In some embodiments, optionally, the circumferential side of the motor assembly 400 is spaced apart from the side wall of the first recessed portion 220 .
[0058] A gap is left between the motor assembly 400 and the side wall of the first recessed portion 220 , and the gap provides a heat dissipation space for the motor assembly 400 , so that the motor assembly 400 can dissipate heat stably, thereby ensuring the operational stability of the motor assembly 400 .
[0059] In some embodiments, optionally, the cooking device includes any one of the following: an oven, a steam oven, and a microwave oven-steamer.
[0060] This embodiment mainly improves the space utilization rate of the hot air oven by rearranging the spatial positions of the motor assembly 400 and the fan blades 300, so that the bottom-controlled oven can get rid of the bulky appearance of the "big butt" when adding the hot air function.
[0061] The air guide hood 200 is installed on the cavity wall of the cooking cavity 110, and the space between the air guide hood 200 and the cavity wall serves as the air guide cavity 210. The fan blades 300 are located in the air guide cavity 210. Driven by the motor assembly 400, the fan blades 300 can rotate in the air guide cavity 210. The fan blades 300 can blow the airflow from the air outlet 130 into the cooking cavity 110, and the gas in the cooking cavity 110 flows into the air guide cavity 210 from the air inlet 120. During the rotation of the fan blades 300, a circulating airflow is formed between the air guide cavity 210 and the cooking cavity 110, which is beneficial to improving the uniformity of temperature distribution in the cooking cavity 110.
[0062] When the motor assembly 400 is installed, at least a portion of the motor assembly 400 is accommodated in the first recessed portion 220, so the motor assembly 400 is not higher than the air guide cover 200, or only a portion of the motor assembly 400 is higher than the air guide cover 200, thereby reducing the space occupied by the motor assembly 400 in the first direction, where the first direction refers to the axial direction of the motor assembly 400. When the motor assembly 400 and the fan blades 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.
[0063] When the motor assembly 400 is accommodated in the first recessed portion 220, the air guide cover 200 can protect the motor assembly 400, making it difficult for the motor assembly 400 to collide with other components. As a result, there is no need to provide a separate protective plate for the motor assembly 400, thus saving the space occupied by the protective plate and helping to further reduce the overall size of the cooking equipment.
[0064] The following scheme only takes the oven with the hot air control function as an example and is applicable to ovens of all structures.
[0065] The motor assembly 400 in this embodiment uses a brushless DC motor and is installed on the top of the cooking cavity 110 .
[0066] The first cavity wall 140 is formed by stamping of a galvanized sheet, and the stretching area is a second recessed portion 150 and an air inlet 120 for accommodating the fan blade 300, and is directly integrally formed with the air outlet 130.
[0067] The air guide cover 200 is stamped from galvanized sheet and installed on the first cavity wall 140. The recessed design in the middle provides an installation position for the motor assembly 400, avoiding the motor assembly 400 from being installed on the maximum outer plane of the air guide cover 200, while ensuring that the motor assembly 400 and the fan blades 300 can be effectively distributed inside the oven.
[0068] The fan blade 300 is installed in the recessed area of the first cavity wall 140 and is located between the wind guide cover 200 and the first cavity wall 140. The recessed area of the first cavity wall 140 provides sufficient movement space for the fan blade 300 while maintaining the compactness of the overall structure.
[0069] The space optimization of this structural design is due to the downward depression of the first cavity wall 140 and the downward contoured depression of the air guide cover 200, which accommodates the installation of the fan blades 300 and the motor assembly 400. Finally, the outer cover is used directly to protect the motor without the need for an additional motor guard plate.
[0070] The circular recessed area of the first cavity wall 140 may be replaced with a shape other than a circle.
[0071] In the present invention, the term "plurality" means two or more than two, unless otherwise clearly defined. The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0072] In the description of this specification, the description of the terms "one embodiment", "some embodiments", "specific embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
