Description

Technical Field

[0001] This utility model relates to the field of heat dissipation motor technology, and in particular to a heat dissipation motor with a compact structure for ovens. Background Technology

[0002] As an indispensable appliance in modern kitchens, the internal cooling motor of an oven is crucial for ensuring the normal operation and extending the lifespan of the device. Traditional oven cooling motors primarily use shaded-pole motors, which are widely used due to their high temperature resistance, long lifespan, and stable performance. However, with technological advancements and changing user needs, higher demands are being placed on the functionality of ovens, particularly on the performance of the cooling motor in high-speed and dual-speed operation modes.

[0003] However, while existing shaded-pole motors can meet basic operating conditions, they fall short when faced with more demanding requirements such as high speeds and dual-speed operation. To meet these requirements, the motor itself must be thickened to accommodate more components and greater driving power. Unfortunately, this increased motor thickness directly leads to challenges in the overall oven structural design, particularly reducing the effective volume of the inner liner. This not only affects the user experience but also limits the product's market competitiveness.

[0004] The purpose of this invention is to solve the problem of excessive height in traditional cooling motors after performance improvements. Utility Model Content

[0006] A compact heat dissipation motor for an oven includes a motor with a motor shaft mounted on it. The motor shaft is fitted with a front motor bracket, which is fixedly connected to the motor. A motor mounting plate is mounted on the front motor bracket. One side of the mounting plate has a protrusion, and the other side has a recess corresponding to the protrusion. The front motor bracket is installed within the recess. An impeller is mounted on one end of the motor shaft.

[0007] The oven cooling motor with a compact structure as described above has an impeller comprising at least two fan blades, one side of which has an inclined portion.

[0008] The oven has a compact heat dissipation motor as described above, the motor including a motor frame, the motor frame having chamfered edges.

[0009] The oven-use compact heat dissipation motor described above has an angle range of 30 degrees to 60 degrees for the tilting portion.

[0010] As described above, a compact heat dissipation motor for an oven has at least one mounting hole on the protrusion for connecting the motor mounting plate via fasteners.

[0011] The oven has a compact heat dissipation motor as described above, wherein the diameter of the motor is greater than its height.

[0012] Implementing the embodiments of this utility model has the following beneficial effects:

[0013] 1. This utility model proposes a compact heat dissipation motor for ovens. Through innovative design, it significantly reduces the overall height of the motor while maintaining or even improving its heat dissipation performance. Specifically, by designing the motor mounting plate with a protrusion on one side and a corresponding recess on the other, and by securely mounting the front motor bracket in the recess, it achieves efficient space utilization and a highly compact structure.

[0014] In summary, this invention solves the problem of excessive height in traditional cooling motors after performance improvements. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, this utility model proposes a compact heat dissipation motor for an oven, including a motor 1, with a motor shaft 2 mounted on the motor 1. The motor shaft 2 is fitted with a front motor bracket 3, which is fixedly connected to the motor 1. A motor mounting plate 4 is mounted on the front motor bracket 3. One side of the motor mounting plate 4 has a protrusion 41, and the other side has a corresponding recess. The front motor bracket 3 is installed within the recess. An impeller 5 is mounted on one end of the motor shaft 2. By designing the motor mounting plate 4 with a protrusion 41 on one side and a corresponding recess on the other, the front motor bracket 3 can be securely mounted within the recess, thus achieving efficient space utilization and reducing the height of the motor 1 and the motor mounting plate 4 after installation. The motor shaft 2 passes through the front motor bracket 3 and extends to the outside, with the impeller 5 mounted on one end. When the motor is running, the motor shaft drives the impeller to rotate, generating airflow to effectively dissipate heat from inside the oven.

[0023] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the impeller 5 includes at least two fan blades 51, one side of which has an inclined portion 52. The at least two inclined portions 52 form a concave space. During installation, the protrusion 41 on the motor mounting plate 4 is embedded in this concave space, further reducing the height between the motor portion and the motor mounting plate, thereby significantly reducing the overall structural height and making it more suitable for applications with limited space.

[0024] Optionally, in some embodiments, the angle of the tilting portion 52 ranges from 30 degrees to 60 degrees. Specifically, the design of the tilt angle affects the interaction between the fan blade 51 and the air, thereby determining the intensity and direction of the generated airflow. A smaller angle (close to 30 degrees) helps to guide the airflow more concentrated in a specific direction, improving local cooling efficiency; while a larger angle (close to 60 degrees) can increase the airflow coverage area and enhance the overall heat dissipation effect.

[0025] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the motor 1 includes a motor frame 6, the motor frame 6 having a chamfer 61. The main purpose of the chamfer 61 is to reduce the edge of the motor frame 6 so that it will not physically conflict or obstruct the motor mounting plate 4 during assembly. This design makes the space between the motor frame 6 and the motor mounting plate 4 more coordinated and compact, ensuring the smooth assembly of the entire heat dissipation motor system. In addition, this design allows designers to optimize the layout within a limited space, achieving higher space utilization and better heat dissipation performance.

[0026] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the protrusion 41 is provided with at least one mounting hole for connecting the motor mounting plate 4 to fasteners. The design of the mounting hole allows for mechanical connection of the motor mounting plate 4 to other key components using fasteners (such as screws, bolts, etc.). Specifically, these mounting holes are located on the protrusion 41 to ensure precise positioning during assembly and to provide sufficient clamping force through the fasteners to maintain tight contact between the components. This connection method not only enhances the rigidity and stability of the overall structure but also effectively prevents loosening or displacement caused by vibration or other external forces. Furthermore, the position and number of mounting holes can be adjusted according to actual needs to adapt to different assembly requirements and space constraints.

[0027] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the diameter of the motor 1 is greater than its height. The motor 1 employs a larger diameter and a smaller height design, which expands the entire motor horizontally while compressing its vertical dimensions. This flattened design not only helps reduce the overall height of the motor but also effectively utilizes lateral space to accommodate more heat dissipation or functional components, thereby improving heat dissipation efficiency without increasing the motor's height.

[0028] Example 1:

[0029] This utility model proposes a compact heat dissipation motor for an oven, including a motor 1 and a motor shaft 2. The motor shaft 2 is fitted with a front motor bracket 3, which is fixedly connected to the motor 1. A motor mounting plate 4 is mounted on the front motor bracket 3. One side of the mounting plate 4 has a protrusion 41, and the other side has a corresponding recess. The front motor bracket 3 is installed within the recess. An impeller 5 is mounted on one end of the motor shaft 2. By designing the motor mounting plate 4 with a protrusion 41 on one side and a corresponding recess on the other, the front motor bracket 3 can be securely installed within the recess, thus achieving efficient space utilization and reducing the height of the motor 1 and the mounting plate 4 after installation. The motor shaft 2 passes through the front motor bracket 3 and extends to the outside, with the impeller 5 mounted on one end. When the motor is running, the motor shaft drives the impeller to rotate, generating airflow to effectively dissipate heat from inside the oven. The diameter of the motor 1 is greater than its height. Motor 1 employs a larger diameter and smaller height design, which expands the entire motor horizontally while compressing its vertical dimensions. This flattened design not only helps reduce the overall height of the motor but also effectively utilizes lateral space to accommodate more heat dissipation or functional components, thereby improving heat dissipation efficiency without increasing the motor's height.

[0030] The impeller 5 includes at least two fan blades 51, with an inclined portion 52 on one side of each blade 51. The at least two inclined portions 52 form a concave space. During installation, the protrusion 41 on the motor mounting plate 4 is embedded in this concave space, further reducing the height between the motor and the mounting plate, thus significantly lowering the overall structural height and making it more suitable for applications with limited space. The angle of the inclined portion 52 ranges from 30 degrees to 60 degrees. Specifically, the design of the tilt angle affects the interaction between the fan blades 51 and the air, thereby determining the intensity and direction of the generated airflow. A smaller angle (close to 30 degrees) helps to guide the airflow more concentrated in a specific direction, improving local cooling efficiency; while a larger angle (close to 60 degrees) increases the airflow coverage area, enhancing the overall heat dissipation effect.

[0031] The motor 1 includes a motor frame 6, which has a chamfer 61. The chamfer 61 is designed to reduce the physical conflict or obstruction between the motor frame 6 and the motor mounting plate 4 during assembly by cutting off part of the edge. This design makes the space between the motor frame 6 and the motor mounting plate 4 more coordinated and compact, ensuring the smooth assembly of the entire heat dissipation motor system. In addition, this design allows designers to optimize the layout within a limited space, achieving higher space utilization and better heat dissipation performance.

[0032] The protrusion 41 has at least one mounting hole for connecting the motor mounting plate 4 to fasteners. The design of the mounting hole allows for mechanical connection of the motor mounting plate 4 to other critical components using fasteners such as screws and bolts. Specifically, these mounting holes are located on the protrusion 41 to ensure precise positioning during assembly and to provide sufficient clamping force through the fasteners to maintain tight contact between the components. This connection method not only enhances the rigidity and stability of the overall structure but also effectively prevents loosening or displacement caused by vibration or other external forces. Furthermore, the position and number of mounting holes can be adjusted according to actual needs to adapt to different assembly requirements and space constraints.

[0033] Specifically, the working principle of this invention is as follows:

[0034] A compact heat dissipation motor for an oven is disclosed. The motor includes a motor 1, a motor shaft 2, a front motor bracket 3, a motor mounting plate 4, and an impeller 5. The motor shaft 2 passes through the front motor bracket 3 and extends to the outside, with the impeller 5 mounted at one end. One side of the motor mounting plate 4 has a protrusion 41, and the other side has a corresponding recess, allowing the front motor bracket 3 to be securely mounted within the recess, thus achieving efficient space utilization and reducing the overall height. When the motor 1 is running, the motor shaft 2 drives the impeller to rotate, generating airflow to effectively dissipate heat from the oven interior. Furthermore, the motor 1 employs a larger diameter and a smaller height design, further optimizing the spatial layout and improving heat dissipation efficiency.

[0035] The impeller 5 includes at least two blades 51, each blade having an inclined portion 52 on one side, which together form a concave space. During installation, the protrusion 41 on the motor mounting plate 4 is embedded in this concave space, significantly reducing the height between the motor and the motor mounting plate, making it more suitable for applications with limited space.

[0036] The motor 1 includes a motor frame 6 with a chamfer 61 to prevent structural interference with the motor mounting plate 4, ensuring a smooth and tight connection during assembly. The protrusion 41 has at least one mounting hole, allowing the motor mounting plate 4 to be mechanically connected to other key components using fasteners (such as screws and bolts), enhancing the rigidity and stability of the overall structure. This design not only simplifies the assembly process and reduces installation errors but also improves the stability and durability of the equipment.

[0037] In summary, this invention solves the problem of excessive height in traditional cooling motors after performance improvements.
