Abstract
Description
Technical Field
[0001] This application relates to the field of cooking equipment technology, and more particularly to a cooking device. Background Technology
[0002] As people's demand for roasted foods, such as roast chicken and roast duck, increases in daily life, the roasting function in cooking equipment is becoming more and more sophisticated.
[0003] In related technologies, cooking equipment includes an inner pot with a cooking cavity; and a mounting shell on the outside of the inner pot, with a certain gap between the mounting shell and the outer wall of the inner pot. The mounting shell is used to mount electronic components and other parts of the cooking equipment. The cooking equipment also includes a drive motor, an adapter, and a rotating baking rod. The rotating baking rod is set in the cooking cavity and is used to load food. Since high temperatures can affect the lifespan of the drive motor, the drive motor is set outside the mounting shell. One end of the adapter is connected to the output shaft of the drive motor, and the other end is connected to one end of the rotating baking rod. The other end of the rotating baking rod is rotatably connected to the inner pot, so that the output shaft of the drive motor drives the rotating baking rod to rotate through the adapter. In order to roast larger foods such as chicken and duck, the rotating baking rod can be tilted inside the cooking cavity. Correspondingly, the axial direction of the output shaft of the drive motor is also tilted relative to the vertical and horizontal directions, so that the output shaft of the drive motor and the adapter are on the same straight line as the axis of the rotating baking rod. Therefore, the installation position of the drive motor has a certain tilt angle.
[0004] However, because the drive motor is tilted relative to the mounting housing, there may be installation deviations. This can cause a gap between the output shaft of the drive motor and the adapter, and between the adapter and the inner pot, which connects the cooking cavity. During cooking, hot air in the cooking cavity leaks to the drive motor through this gap, affecting both the lifespan of the drive motor and the cooking results. Utility Model Content
[0005] In view of the above problems, this application provides a cooking device that aims to solve the technical problem of poor sealing performance between the inner pot and the drive motor, thereby improving the sealing performance of the inner pot, extending the life of the drive motor, and improving the cooking effect.
[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0007] This application provides a cooking device, including:
[0008] The equipment body includes an inner pot, which has a cooking cavity, and the side wall of the inner pot has a mounting hole communicating with the cooking cavity.
[0009] The drive mechanism is located on the outside of the inner liner and is spaced apart from the outer wall of the inner liner. The power output end of the drive mechanism has a drive shaft, which can rotate around its own axis, and part of the drive shaft extends into the inner liner.
[0010] The rotating rack is located inside the cooking cavity to support food. One end of the rotating rack is connected to the drive shaft, and the other end is rotatably connected to the cavity wall of the cooking cavity, so that the drive shaft drives the rotating rack to rotate around its own axis.
[0011] A seal is disposed around the outer periphery of the drive shaft and located between the drive mechanism and the outer wall surface of the inner liner, wherein the seal at least abuts against the outer wall surface of the inner liner, the abutment area of the seal and the inner liner is located at the outer edge of the mounting hole, and the inner wall of the seal at least partially contacts and seals against the outer wall of the drive shaft.
[0012] This design has two advantages. First, the sealing element allows the gap between the drive mechanism and the mounting hole on the inner pot to be sealed, thereby improving the sealing performance between the drive mechanism and the inner pot. This prevents hot air in the cooking cavity from leaking through the gap to the drive mechanism during operation, which would affect the lifespan of the drive mechanism and thus improve the lifespan of the cooking equipment and the cooking effect. Second, while ensuring a gap between the drive mechanism and the outside of the inner pot, its drive shaft can partially extend into the inner pot and connect directly to the rotating rod, saving the need for an intermediate adapter, reducing costs, and reducing the installation deviation between the drive shaft and the rotating rod, thereby improving the assembly accuracy between the two.
[0013] In some embodiments, the inner wall of the seal has a sealing protrusion extending circumferentially, which contacts and seals against the outer wall of the drive shaft.
[0014] With this configuration, on the one hand, the sealing protrusion presses against the drive shaft under the tightening force of the seal, thereby improving the sealing effect between the seal and the drive shaft; on the other hand, the sealing protrusion can compensate for the concentricity deviation between the seal and the drive shaft, so as to further improve the sealing effect between the seal and the drive shaft.
[0015] In some embodiments, there are at least two sealing protrusions, and the at least two sealing protrusions are sequentially spaced apart along the height direction of the seal; and / or,
[0016] The seal is a cylindrical structure, and the sealing protrusion is an annular structure; and / or,
[0017] The sealing protrusion and the sealing element are an integral structure.
[0018] This design has several advantages. First, the presence of at least two sealing protrusions enhances the sealing effect between the seal and the drive shaft while reducing friction, thereby improving the transmission efficiency of the drive motor. Second, the seal has a cylindrical structure, and the sealing protrusions have an annular structure, allowing the sealing protrusions to seal the outer circumference of the drive shaft 360°, thus improving the sealing effect between the seal and the drive shaft. Third, the sealing protrusions and the seal are integrated into one structure, thereby improving the structural compactness of the seal.
[0019] In some embodiments, the edge of the mounting hole has an annular flange structure extending outward from the inner liner, and the end face of the seal facing the inner liner has a sealing groove that matches the flange structure. When the seal abuts against the outer wall of the inner liner, the flange structure is inserted into the sealing groove and sealed to the groove wall.
[0020] This design transforms the surface-to-surface sealing structure between the seal and the inner liner into a raised and recessed sealing structure, improving the sealing effect between the seal and the inner liner, preventing hot air from the cooking cavity from being transmitted to the drive mechanism, and extending the service life of the drive mechanism.
[0021] In some embodiments, the outer periphery of the sealing groove has a deformable portion extending toward the inner liner. The deformable portion is annular. When the flange structure is inserted into the sealing groove, the deformable portion abuts against the outer wall surface of the inner liner and deforms.
[0022] This design ensures an interference fit between the seal and the outer wall of the inner liner, resulting in a compressed seal that further enhances the sealing effect between the seal and the inner liner.
[0023] In some embodiments, the cooking device further includes a motor bracket located on the outside of the inner pot, a first end of the motor bracket being fixedly connected to the inner pot, a second end of the motor bracket located on the side of the first end away from the inner pot and having a preset distance between them, and a drive mechanism including a drive motor fixedly connected to the second end of the motor bracket.
[0024] This design limits the distance between the drive motor, which is fixedly connected to the second end of the motor bracket, and the inner pot, thereby reducing the heat conducted from the cooking cavity to the drive motor, increasing the lifespan of the drive motor, and consequently extending the lifespan of the cooking equipment.
[0025] In some embodiments, the height dimension of the seal is greater than the height dimension of the motor bracket along the axial direction of the drive shaft.
[0026] This design allows the drive motor to be fixedly connected to the second end of the motor bracket while increasing the height of the seal to ensure a tight fit between the seal and the outer wall of the inner liner. It also increases the contact area between the seal and the drive shaft, further improving the sealing effect between the inner liner and the drive mechanism.
[0027] In some embodiments, the preset distance between the first end and the second end of the motor bracket is greater than or equal to 10 mm.
[0028] This design further limits the distance between the drive motor and the inner pot, thereby reducing the heat transferred from the cooking cavity to the drive motor.
[0029] In some embodiments, the motor bracket includes two sub-brackets, which are vertically spaced along the inner liner to form a clearance space between them. The first end of each sub-bracket is connected to the inner liner, and the drive motor is fixed to the second end of the two sub-brackets. At least a portion of the drive shaft and the seal are located in the clearance space.
[0030] This design improves the structural compactness between the motor bracket, drive motor, drive shaft, and seals, reducing space utilization in the cooking equipment and thus reducing the size of the cooking equipment.
[0031] In some embodiments, the sub-bracket has a heat dissipation section, a first bending section and a second bending section. The heat dissipation section extends axially along the drive shaft. The first bending section and the second bending section are located at opposite ends of the heat dissipation section, and the first bending section and the second bending section extend in the same direction. The first bending section is connected to the inner liner, and the drive motor is fixedly connected to the second bending section.
[0032] This design increases the connection area between the first and second bending sections and the drive motor and the outer wall of the inner pot at both ends of the motor bracket, thereby improving the reliability and stability of the drive motor's fixation relative to the inner pot. The heat dissipation section provides a preset distance between the drive motor and the inner pot, thereby reducing the heat transferred from the cooking cavity to the drive motor, increasing the lifespan of the drive motor, and thus extending the lifespan of the cooking equipment.
[0033] In some embodiments, the heat dissipation section, the first bending section, and the second bending section are both plate-like structures, and the heat dissipation section has a plurality of heat dissipation holes arranged at intervals; and / or,
[0034] At least one of the heat dissipation section, the first bend section, and the second bend section has a heat insulation element; and / or,
[0035] The motor bracket also includes a reinforcing plate, which is located on the side of the two second bends away from the heat dissipation section, and the drive motor is connected to the reinforcing plate.
[0036] This design has several advantages. First, the heat dissipation holes on the heat dissipation section allow heat transferred from the cooking cavity to dissipate into the surrounding environment as it passes through the heat dissipation section, thereby reducing the amount of heat transferred from the cooking cavity to the drive motor. Second, at least one of the heat dissipation section, the first bending section, and the second bending section has a heat insulation component, which increases the thermal resistance between the drive motor and the inner pot, further reducing the amount of heat transferred from the cooking cavity to the drive motor. Third, the reinforcing plate increases the connection strength between the drive motor and the motor bracket, improving the reliability and stability of the connection between the drive motor and the motor bracket.
[0037] In some embodiments, the outer wall surface near the top of the rear side of the inner liner has a mounting protrusion, the mounting protrusion has a mounting surface, and the first bent section has a connecting surface that matches the mounting surface. The connecting surface is configured to be parallel to and fit against the mounting surface. An angle is formed between the mounting surface and the wall surface of the rear side wall of the inner liner.
[0038] This design, on the one hand, increases the connection area between the first bending section and the mounting protrusion, thereby improving the reliability and stability of the connection between the drive motor and the inner liner through the motor bracket; on the other hand, the mounting surface forms an angle with the rear side wall of the inner liner to accommodate the tilt angle of the rotating baking rod in the accommodating cavity, thereby improving the assembly accuracy between the drive motor, drive shaft and rotating baking rod.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0061] With the increasing demand for roasted foods, such as roasted chicken and roasted duck, the roasting function in cooking equipment has become more and more sophisticated. Therefore, this application provides a cooking device with a roasting function.
[0062] In some embodiments,
[0063] The cooking equipment includes an inner pot with a cooking cavity; and a mounting shell on the outside of the inner pot, with a certain gap between the mounting shell and the outer wall of the inner pot. The mounting shell is used to mount electronic components and other parts of the cooking equipment. The cooking equipment also includes a drive motor, an adapter, and a rotating baking rod. The rotating baking rod is set in the cooking cavity and is used to load food. Since high temperatures can affect the lifespan of the drive motor, the drive motor is set outside the mounting shell. One end of the adapter is connected to the output shaft of the drive motor, and the other end is connected to one end of the rotating baking rod. The other end of the rotating baking rod is rotatably connected to the inner pot, so that the output shaft of the drive motor drives the rotating baking rod to rotate through the adapter. In order to roast larger foods such as chicken and duck, the rotating baking rod can be tilted in the cooking cavity. Correspondingly, the axial direction of the output shaft of the drive motor is also tilted relative to the vertical and horizontal directions, so that the output shaft of the drive motor and the adapter are on the same straight line as the axis of the rotating baking rod. Therefore, the installation position of the drive motor has a certain tilt angle.
[0064] However, because the drive motor is tilted relative to the mounting housing, there may be installation deviations. This can cause a gap between the output shaft of the drive motor and the adapter, and between the adapter and the inner pot, which connects the cooking cavity. During cooking, hot air in the cooking cavity leaks to the drive motor through this gap, affecting both the lifespan of the drive motor and the cooking results.
[0065] To address the aforementioned technical problems, this application provides a cooking device that improves the sealing performance of the inner pot, extends the service life of the drive motor, and enhances the cooking effect of the device.
[0066] The cooking equipment provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0067] The cooking equipment provided in this application includes, but is not limited to, ovens, steam ovens, and microwave-steam-grill combos, which can be used to bake food. The content of this application will now be described in detail with reference to the accompanying drawings to enable those skilled in the art to gain a clearer and more comprehensive understanding of its contents.
[0068] First, it should be noted that when the operator uses the cooking equipment 100 to process the ingredients, the side of the cooking equipment 100 facing the operator is the front side of the cooking equipment 100, and the side of the cooking equipment 100 away from the operator is the rear side of the cooking equipment 100.
[0069] As shown in the attached diagram, Figure 1 This is a schematic diagram of the structure of a cooking device provided in an embodiment of this application. Figure 2 A cross-sectional view of a cooking device from a top-down perspective, provided as an embodiment of this application. Figure 3 for Figure 2 A magnified view of a portion at point A. (Combined with...) Figure 1 , Figure 2 and Figure 3 As shown, the cooking device 100 includes a device body 110, a drive mechanism 120, a rotating rod 130, and a sealing element 140.
[0070] Among them, such as Figure 1 As shown, the device body 110 includes an inner liner 111, which has a cooking cavity 112. The side wall of the inner liner 111 has a mounting hole 1111 communicating with the cooking cavity 112. For example, the mounting hole 1111 may be provided on the rear side wall of the inner liner 111.
[0071] In some embodiments, the device body 110 also includes a door, which is disposed on the side of the inner liner 111 with an opening, and the door is rotatably connected to the lower side wall of the opening of the inner liner 111 to open or close the cooking cavity 112, thereby facilitating the placement of food into or removal from the cooking cavity 112. The door and the inner liner 111 can be rotatably connected by a hinge connection, a pivot pin connection, etc.
[0072] Combination Figure 2 and Figure 3 As shown, the drive mechanism 120 in the cooking device 100 is disposed outside the inner pot 111 and has a gap between it and the outer wall surface of the inner pot 111 to increase the distance between the drive mechanism 120 and the inner pot 111, thereby reducing the heat leakage from the cooking cavity 112 to the drive mechanism 120. For example, the size of this gap is greater than or equal to 10 mm. In addition, the power output end of the drive mechanism 120 has a drive shaft 121, which can rotate around its own axis. The drive motor is coaxially connected to the drive shaft 121. For example, the drive mechanism 120 includes a drive motor and an output shaft, and the drive shaft 121 is the output shaft. Alternatively, the drive shaft 121 is an additional shaft-like member coaxially connected to the output shaft. The drive shaft 121 extends into the inner pot 111. Therefore, no adapter is required between the end of the drive shaft 121 near the cooking cavity 112 and the rotisserie rod 130.
[0073] The rotating rod 130 is located inside the cooking cavity 112 to support the food. One end of the rotating rod 130 is connected to the drive shaft 121, and the other end is rotatably connected to the cavity wall of the cooking cavity 112, so that the drive shaft 121 drives the rotating rod 130 to rotate around its own axis, thereby causing the food to rotate evenly in the cooking cavity 112, so that the food can be heated evenly.
[0074] In some embodiments, the rotisserie rod 130 can be rotatably connected to any wall of the cooking cavity 112. To further increase the extension length of the rotisserie rod 130 in the cooking cavity 112, for example, one end of the rotisserie rod 130 connected to the drive shaft 121 can be located on the upper part of the rear side wall of the cooking cavity 112, and the other end of the rotisserie rod 130 rotatably connected to the wall of the cooking cavity 112 can be located on the front bottom wall of the cooking cavity 112. Furthermore, when one end of the rotisserie rod 130 connected to the drive shaft 121 is located on one of the left and right sides of the upper part of the rear side wall of the cooking cavity 112, the other end of the rotisserie rod 130 rotatably connected to the wall of the cooking cavity 112 is located on the other side of the left and right sides of the front bottom wall of the cooking cavity 112, so that the rotisserie rod 130 extends along the spatial diagonal of the cooking cavity 112, thereby satisfying the cooking of larger food items.
[0075] In other embodiments, such as Figure 3 As shown, a coupling 160 is provided between the rotisserie rod 130 and the drive shaft 121. The coupling 160 is a cylindrical component with a connecting channel. At least a portion of the rotisserie rod 130 and the drive shaft 121 are disposed in the connecting channel and fixedly connected to the coupling 160, thereby increasing the connection strength between the rotisserie rod 130 and the drive shaft 121. Exemplarily, the fixed connection methods between the coupling 160 and the drive shaft 121 and the rotisserie rod 130 include, but are not limited to, welding, internal and external threaded connection, snap-fit, pin connection, and bonding. Furthermore, the drive motor in the drive mechanism 120 drives the coupling 160 through the drive shaft 121, performing axial transmission with the rotisserie rod 130. Therefore, the drive motor is not subjected to direct force from the food on the rotisserie rod 130, thereby reducing the damage rate of the drive motor and the drive shaft 121 and increasing the service life of the drive mechanism 120.
[0076] In addition, combined Figure 2 and Figure 3As shown, the sealing element 140 in the cooking device 100 surrounds the outer periphery of the drive shaft 121 and is located between the drive mechanism 120 and the outer wall surface of the inner pot 111, thereby creating a sealed connection between the drive mechanism 120 and the inner pot 111 and improving the sealing performance between them. Specifically, the sealing element 140 at least abuts against the outer wall surface of the inner pot 111, and the contact area between the sealing element 140 and the inner pot 111 is located at the outer edge of the mounting hole 1111, thus preventing hot air in the cooking cavity 112 from leaking out of the inner pot 111 through the mounting hole 1111, reducing the impact of heat on the service life of the drive motor. Furthermore, the inner wall of the sealing element 140 at least partially contacts and seals against the outer wall of the drive shaft 121, thereby preventing hot air in the cooking cavity 112 from leaking to the drive mechanism 120 through the gap between the mounting hole 1111 and the drive shaft 121, further reducing the impact of heat on the service life of the drive motor.
[0077] As an example, the seal 140 is a sheet-like element that is disposed on the outer periphery of the drive shaft 121 in a multi-layered manner and abuts against the outer wall surface of the inner liner 111.
[0078] In this application, the sealing element 140 is provided so that the gap between the drive mechanism 120 and the mounting hole 1111 on the inner pot 111 can be sealed by the sealing element 140, thereby improving the sealing performance between the drive mechanism 120 and the inner pot 111. This prevents hot air in the cooking cavity 112 from leaking from the gap between the two to the drive mechanism 120 during the operation of the cooking equipment 100, which would affect the service life of the drive mechanism 120 and thus improve the service life of the cooking equipment 100. In addition, while ensuring that the drive mechanism 120 has a gap with the outside of the inner pot 111, its drive shaft 121 can partially extend into the inner pot 111 and directly connect with the rotating rod 130, eliminating the need for intermediate adapters, saving costs, and reducing the installation deviation between the drive shaft 121 and the rotating rod 130, thereby improving the assembly accuracy between the two.
[0079] To further enhance the sealing performance between the seal 140 and the drive shaft 121, such as Figure 3 As shown, the inner wall of the seal 140 has a circumferentially extending sealing protrusion 141, which contacts and seals against the outer wall of the drive shaft 121. This arrangement serves two purposes: firstly, the sealing protrusion 141, under the tightening force of the seal 140, presses against the drive shaft 121, thereby improving the sealing effect between the seal 140 and the drive shaft 121; secondly, the sealing protrusion 141 can compensate for concentricity deviations between the seal 140 and the drive shaft 121, further enhancing the sealing effect between them.
[0080] As an example, the inner wall of the seal 140 has at least two sealing protrusions 141, which are arranged sequentially at intervals along the height direction of the seal 140. Here, the height direction of the seal 140 is the axial direction of the drive shaft 121. Specifically, the number of sealing protrusions 141 can be two, three, four, five, six, etc., thereby further enhancing the sealing effect between the seal 140 and the drive shaft 121. Furthermore, during the rotation of the drive shaft 121 around its own axis, the friction between the seal 140 and the drive shaft 121 can be reduced, thereby improving the transmission efficiency of the drive motor.
[0081] Secondly, as an example, the seal 140 has a cylindrical structure and the sealing protrusion 141 has an annular structure, so that the sealing protrusion 141 seals the outer periphery of the drive shaft 121 360°, thereby improving the sealing effect between the seal 140 and the drive shaft 121.
[0082] Three examples illustrate that the sealing protrusion 141 and the seal 140 are an integral structure, thereby improving the structural compactness of the seal 140.
[0083] In addition, in some embodiments, the sealing protrusion 141 and the sealing member 140 are integral structures, the sealing member 140 is a cylindrical structure, the sealing protrusion 141 is an annular structure, and at least two sealing protrusions 141 are provided on the inner wall of the sealing member 140 along the height direction of the sealing member 140, so as to further improve the sealing effect between the sealing member 140 and the drive shaft 121.
[0084] Continue as Figure 3 As shown, the edge of the mounting hole 1111 has an annular flange structure 1112 extending outward from the inner liner 111. The end face of the sealing member 140 facing the inner liner 111 has a sealing groove that matches the flange structure 1112. When the sealing member 140 abuts against the outer wall of the inner liner 111, the flange structure 1112 is inserted into the sealing groove and sealed to the groove wall. This transforms the surface-to-surface sealing structure between the sealing member 140 and the inner liner 111 into a raised and recessed sealing structure, thereby improving the sealing effect between the sealing member 140 and the inner liner 111 and preventing hot air in the cooking cavity 112 from leaking out of the inner liner, affecting the service life of the drive mechanism 120 located on the outer side of the inner liner, and thus improving the service life of the cooking equipment 100.
[0085] Furthermore, such as Figure 3As shown, the outer periphery of the sealing groove has a deformable portion 142 extending toward the inner liner 111. The deformable portion 142 is annular. When the flange structure 1112 is inserted into the sealing groove, the deformable portion 142 abuts against the outer wall surface of the inner liner 111 and deforms, thereby making the seal 140 and the outer wall surface of the inner liner 111 an interference fit, and the seal 140 and the outer wall surface of the inner liner 111 are in a compressed state, thereby further improving the sealing effect between the seal 140 and the inner liner 111.
[0086] In addition, such as Figure 4 and Figure 5 As shown, the cooking device 100 also includes a motor bracket 150, which is located on the outside of the inner pot 111. The first end of the motor bracket 150 is fixedly connected to the inner pot 111, and the second end of the motor bracket 150 is located on the side of the first end facing away from the inner pot 111, with a preset distance between them. The drive mechanism 120 includes a drive motor, which is fixedly connected to the second end of the motor bracket 150. The motor bracket 150 allows the drive motor to be fixedly connected to the inner pot 111 via the motor bracket 150, while the drive shaft 121 at the output end of the drive motor can partially extend into the inner pot 111 and connect to the rotisserie rod 130, thus eliminating the need for intermediate adapters and saving costs. Furthermore, the preset distance between the first and second ends of the motor bracket 150 limits the distance between the drive motor fixedly connected to the second end of the motor bracket 150 and the inner pot 111, reducing the heat transferred from the cooking cavity 112 to the drive motor via heat conduction, thereby increasing the service life of the drive motor and consequently, the service life of the cooking device 100.
[0087] Furthermore, along the axial direction of the drive shaft 121, the height dimension of the seal 140 is greater than the height dimension of the motor bracket 150. This allows the drive motor to be fixedly connected to the second end of the motor bracket 150 while increasing the height dimension of the seal 140. This ensures a tight fit between the seal 140 and the outer wall of the inner liner, and increases the contact area between the seal 140 and the drive shaft 121. This further improves the sealing effect of the seal 140, preventing hot air in the cooking cavity 112 from leaking to the outside of the inner liner through the mounting hole 1111, and preventing hot air in the cooking cavity 112 from being transmitted to the drive motor through the gap between the seal 140 and the drive shaft 121, thus affecting the service life of the drive motor and improving the service life of the cooking equipment 100.
[0088] For example, the preset distance between the first end and the second end of the motor bracket 150 is greater than or equal to 10mm. Specifically, the preset distance between the two can be 10mm, 11mm, 12mm, 15mm, 18mm, 20mm, etc.
[0089] In some embodiments, combined with Figure 4 and Figure 5 As shown, the motor bracket 150 includes two sub-brackets 151, which are vertically spaced along the inner pot 111 to form a clearance space 152 between them to accommodate the extension path of the drive shaft 121. The first end of each sub-bracket 151 is connected to the inner pot 111, and the drive motor is fixed to the second end of the two sub-brackets 151. At least part of the drive shaft 121 and the seal 140 are located in the clearance space 152, thereby improving the structural compactness of the motor bracket 150, the drive motor, the drive shaft 121 and the seal 140, reducing the space utilization rate in the cooking equipment 100, and thus reducing the spatial size of the cooking equipment 100.
[0090] Furthermore, such as Figure 5 As shown, the sub-support 151 has a heat dissipation section 1511, a first bending section 1512 and a second bending section 1513. The heat dissipation section 1511 extends along the axial direction of the drive shaft 121. The first bending section 1512 and the second bending section 1513 are located at both ends of the heat dissipation section 1511, and the first bending section 1512 and the second bending section 1513 extend in the same direction. The first bending section 1512 is connected to the inner liner 111, and the drive motor is fixed to the second bending section 1513. The first bending section 1512 and the second bending section 1513 increase the connection area between the two ends of the motor bracket 150 and the outer wall of the drive motor and the inner pot 111, respectively, thereby improving the reliability and stability of the drive motor fixed relative to the inner pot 111. The heat dissipation section 1511 reduces the contact area between the drive motor and the inner pot 111 compared to when the drive motor is directly connected to the inner pot 111, and makes the drive motor and the inner pot 111 have a preset distance, thereby reducing the heat conducted from the cooking cavity 112 to the drive motor, improving the service life of the drive motor, and thus improving the service life of the cooking equipment 100.
[0091] As an example, the heat dissipation section 1511, the first bending section 1512 and the second bending section 1513 are all plate-shaped structures, and the heat dissipation section 1511 has a plurality of heat dissipation holes 1514 arranged at intervals, so that the heat transferred from the cooking cavity 112 can be dissipated to the surrounding environment through the heat dissipation holes 1514 when passing through the heat dissipation section 1511, thereby reducing the heat transferred to the drive motor.
[0092] For example, at least one of the heat dissipation section 1511, the first bending section 1512, and the second bending section 1513 has a heat insulation component, thereby increasing the thermal resistance between the drive motor and the inner liner 111 and reducing the heat transferred from the cooking cavity 112 to the drive motor. Alternatively, the heat dissipation section 1511, the first bending section 1512, and the second bending section 1513 are all made of heat insulation material to increase the thermal resistance between the drive motor and the inner liner 111. The heat insulation material can be heat insulation ceramic, glass wool, etc.
[0093] For example, the motor bracket 150 also includes a reinforcing plate 153. The reinforcing plate 153 is disposed on the side of the two second bending sections 1513 opposite to the heat dissipation section 1511. The drive motor is connected to the reinforcing plate 153, thereby increasing the connection strength between the drive motor and the motor bracket 150 and improving the reliability and stability of the connection between the drive motor and the motor bracket 150. Specifically, the reinforcing plate 153 can be formed by bending the second bending section 1513 in the opposite direction from the first bending section 1512. Alternatively, the reinforcing plate 153 can be additionally provided to improve the support strength of the motor bracket 150. For example, in this method, the reinforcing plate 153 and the second bending section 1513 are fixedly connected. The fixed connection can be achieved by welding, bolt and nut connection, snap-fit, pin connection, adhesive bonding, etc.
[0094] In addition, such as Figure 5 As shown, the outer wall surface near the top of the rear side of the inner liner 111 has a mounting protrusion 113. The mounting protrusion 113 has a mounting surface, and the first bending section 1512 has a connecting surface that matches the mounting surface. The connecting surface is configured to be parallel and fit against the mounting surface, thereby increasing the connection area between the first bending section 1512 and the mounting protrusion 113 and improving the reliability and stability of the connection between the drive motor and the inner liner 111 through the motor bracket 150. The mounting surface forms an angle with the wall surface of the rear side of the inner liner 111 to adapt to the tilt angle of the rotating baking rod 130 in the accommodating cavity, thereby improving the assembly accuracy between the drive motor, the drive shaft 121 and the rotating baking rod 130.
[0095] For example, the first bent section 1512 is fixedly connected to the inner liner 111, that is, the connecting surface of the first bent section 1512 is fixedly connected to the mounting surface of the inner liner 111, and the second bent section 1513 is fixedly connected to the drive motor. The fixed connection can be achieved by welding, bolt and nut connection, snap-fit, pin connection, adhesive, etc.
