Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a heat-insulated and steam-proof oven motor. Background Technology

[0002] As an indispensable appliance in the modern kitchen, the oven's design and performance directly impact cooking results and user experience. Traditional ovens typically consist of a heating cavity that generates heat through electric heating elements or gas combustion to reach the desired cooking temperature. To accommodate diverse cooking needs, many modern ovens also feature steam-roasting functions, adding a steam cooking option to traditional baking. This multi-functional design not only improves cooking efficiency but also provides users with more possibilities for culinary creation. However, with the addition of these functions, higher demands are placed on the design of the oven's internal components.

[0003] While existing oven designs largely meet users' cooking needs, they still face several challenges in practical use. This is especially true for ovens with motor-driven components, where the motor shaft extends into the high-temperature oven cavity, exposing the motor's front end to extremely high operating temperatures. This not only accelerates the aging process of the motor's front bearing, reducing its lifespan, but the high-temperature environment can also cause sealing materials (such as silicone seals) to age and harden rapidly, affecting the overall sealing performance and operational stability of the appliance. These problems significantly limit the overall performance and lifespan of the oven.

[0004] The purpose of this invention is to solve the problems of performance degradation and aging of sealing materials at the front end of the motor inside the oven caused by the high-temperature working environment. Utility Model Content

[0007] As described above, in an oven motor that is heat-insulated and steam-proof, a silicone sealing ring is installed at one end of the cylinder.

[0008] As described above, in an oven motor with heat insulation and steam prevention, the silicone sealing ring is provided with a mating part, and one end of the cylinder is provided with a connecting part, the connecting part being engaged with the mating part.

[0009] In the heat-insulating and steam-proof oven motor described above, the connecting part is a retaining ring, the docking part is a retaining groove, and the retaining groove engages with the retaining ring.

[0010] In the heat-insulating and steam-proof oven motor described above, the cross-sectional shape of the thickened portion is rectangular.

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

[0013] 1. In this utility model, the cylinder body and its internal cavity are connected to the mounting groove and are sleeved on the outside of the rotating shaft. One end is provided with a thickened part, which effectively isolates the high-temperature air in the oven cavity, reduces the heat transfer to the front of the motor, protects the internal components of the motor, and improves the reliability and durability of the motor.

[0020] 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.

[0021] like Figures 1 to 2 As shown, this utility model proposes a heat-insulating and steam-proof oven motor, including a bracket fixing frame 1. A rotating shaft 2 is fitted inside the bracket fixing frame 1. The bracket fixing frame 1 has an installation groove 3, which provides installation space for an annular silicone seal and an oil-impregnated bearing fitted outside the rotating shaft 2. A cylindrical body 4 is provided on one side of the bracket fixing frame 1. The cylindrical body 4 has a cavity 41, which communicates with the installation groove 3. The cylindrical body 4 is fitted outside the rotating shaft 2, and a thickened portion 5 is provided at one end of the cylindrical body 4. Specifically, the rotating shaft 2 fitted inside the bracket fixing frame 1 is connected to the installation groove 3, which provides a stable installation space for the annular silicone seal and the oil-impregnated bearing, ensuring smooth operation of the rotating shaft 2 in high-temperature environments. The cylindrical body 4 is located on one side of the bracket fixing frame 1, and its internal cavity 41 is connected to the installation groove 3. The cylindrical body 4 not only fits outside the rotating shaft 2 but also has a thickened portion 5 at one end. This structural design effectively isolates the high-temperature air inside the oven cavity, reducing heat transfer to the front of the motor and thus lowering the operating temperature of the motor's front bearing. Simultaneously, the cylinder 4 and its thickened section 5 also prevent steam intrusion, further protecting the internal components of the motor, significantly reducing the temperature at the annular silicone seal and the oil-impregnated bearing, and extending the lifespan of the silicone seal and the oil-impregnated bearing.

[0022] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, a silicone sealing ring 7 is installed at one end of the cylinder 4. The silicone sealing ring 7 has a mating portion 71, and a connecting portion 6 is provided at one end of the cylinder 4, the connecting portion 6 engaging with the mating portion 71. The silicone sealing ring 7 is installed at one end of the cylinder 4, and the silicone sealing ring 7 engages with the connecting portion 6 at the end of the cylinder 4 via its mating portion 71. This design allows the silicone sealing ring 7 to fit tightly against the end of the cylinder 4, forming an effective sealing barrier. When the oven is operating, the presence of the silicone sealing ring 7 effectively prevents high-temperature gases and steam from entering the gap between the rotating shaft 2 and the cylinder 4, ensuring that the internal components of the motor can operate in a relatively stable temperature environment. The snap-fit ​​design not only simplifies the installation process but also ensures the stability of the sealing ring during long-term use.

[0023] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the connecting part 6 is a retaining ring, and the mating part 71 is a retaining groove, the retaining groove engaging with the retaining ring. During installation, the retaining groove directly engages with the retaining ring, forming a stable and tight connection. This engaging mechanism utilizes a mechanical fitting method to ensure that the silicone sealing ring 7 can be firmly fixed to one end of the cylinder 4 and can maintain its position under high temperature and steam environments, thus achieving the function of quick installation and disassembly.

[0024] Optionally, in some embodiments, the connecting part 6 is a slot and the docking part 71 is a retaining ring.

[0025] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the diameter of the thickened portion 5 is longer than the diameter of the cylinder 4, and the cross-sectional shape of the thickened portion 5 is rectangular. The rectangular cross-section design not only increases the thickness of this portion but also provides a larger surface area to enhance the heat insulation effect. The thickened portion 5 is located at the end of the cylinder 4, near the annular silicone seal and the oil-impregnated bearing. Increasing the material thickness reduces heat conduction from the oven cavity to the annular silicone seal and the oil-impregnated bearing, extending the service life of the silicone seal and the oil-impregnated bearing. This design also has advantages in terms of mechanical strength, enabling it to withstand greater stress during equipment operation without easily deforming or being damaged.

[0026] Example 1:

[0027] This utility model proposes a heat-insulating and steam-proof oven motor, including a bracket fixing frame. A rotating shaft is fitted inside the bracket fixing frame, and the bracket fixing frame has an installation groove. The installation groove provides installation space for an annular silicone seal and an oil-impregnated bearing fitted outside the rotating shaft. A cylindrical body is provided on one side of the bracket fixing frame, and the cylindrical body has a cavity that communicates with the installation groove. The cylindrical body fits outside the rotating shaft, and one end of the cylindrical body has a thickened portion. Specifically, the rotating shaft fitted inside the bracket fixing frame is connected to the installation groove, which provides a stable installation space for the annular silicone seal and the oil-impregnated bearing, ensuring smooth operation of the rotating shaft in high-temperature environments. The cylindrical body is located on one side of the bracket fixing frame, and its internal cavity is connected to the installation groove. The cylindrical body not only fits outside the rotating shaft but also has a thickened portion at one end. This structural design effectively isolates the high-temperature air inside the oven cavity, reducing heat transfer to the front of the motor, thereby lowering the operating temperature of the motor's front bearing. Meanwhile, the cylinder and its thickened section also prevent steam intrusion, further protecting the internal components of the motor, significantly reducing the temperature at the annular silicone seal and the oil-impregnated bearing, and extending the service life of the silicone seal and the oil-impregnated bearing.

[0028] A silicone sealing ring is installed at one end of the cylinder. The silicone sealing ring has a mating part, and a connecting part is located at one end of the cylinder; the connecting part engages with the mating part. The silicone sealing ring, installed at one end of the cylinder, engages with the connecting part at the end of the cylinder via its mating part. This design allows the silicone sealing ring to fit tightly against the end of the cylinder, forming an effective sealing barrier. When the oven is operating, the presence of the silicone sealing ring effectively prevents high-temperature gases and steam from entering the gap between the shaft and the cylinder, ensuring that the internal components of the motor operate in a relatively stable temperature environment. The snap-fit ​​design not only simplifies the installation process but also ensures the stability of the sealing ring during long-term use.

[0029] The connecting part is a retaining ring, and the mating part is a retaining groove, which engages with the retaining ring. During installation, the retaining groove directly engages with the retaining ring, forming a stable and tight connection. This engagement mechanism utilizes mechanical fitting to ensure that the silicone sealing ring can be firmly fixed to one end of the cylinder and maintain its position under high temperature and steam conditions, thus enabling quick installation and disassembly.

[0030] The diameter of the thickened section is longer than that of the main body, and its cross-section is rectangular. This rectangular cross-section not only increases the thickness of this section but also provides a larger surface area to enhance insulation. Located at the end of the main body, near the annular silicone seal and the oil-impregnated bearing, the thickened section reduces heat transfer from the oven cavity to these components, extending their lifespan. This design also offers advantages in mechanical strength, enabling it to withstand greater stress during operation without easily deforming or being damaged.

[0031] The implementation method of Example 2 is as follows:

[0032] The difference between Embodiment 2 and Embodiment 1 is that the connecting part 6 is a slot and the docking part 71 is a retaining ring.

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

[0034] The rotating shaft 2, fitted inside the bracket 1, is connected to the mounting groove 3. The mounting groove 3 provides a stable mounting space for the annular silicone seal and the oil-impregnated bearing, ensuring smooth operation of the rotating shaft 2 in high-temperature environments. The cylindrical body 4 is located on one side of the bracket 1, and its internal cavity 41 is connected to the mounting groove 3. The cylindrical body 4 not only fits around the rotating shaft 2 but also has a thickened section 5 at one end. This structural design effectively isolates the high-temperature air inside the oven cavity, reducing heat transfer to the front of the motor and thus lowering the operating temperature of the motor's front bearing.

[0035] A silicone sealing ring 7 is installed at one end of the cylinder 4. This silicone sealing ring 7 engages with the connecting part 6 (ring) at the end of the cylinder 4 via its mating part 71 (groove), forming an effective sealing barrier. When the oven is operating, high-temperature air and steam attempt to enter the motor through the gap between the rotating shaft 2 and the cylinder 4. The presence of the silicone sealing ring 7 effectively prevents the intrusion of these high-temperature gases and steam, ensuring that the internal components of the motor can operate in a relatively stable temperature environment. The snap-fit ​​design not only simplifies the installation process but also ensures the stability of the sealing ring 7 during long-term use.

[0036] The thickened section 5 has a rectangular cross-sectional shape, increasing its thickness and providing a larger surface area to enhance insulation. Located at the end of the cylinder 4, near the annular silicone seal and the oil-impregnated bearing, the thickened section 5 reduces heat transfer from the oven cavity to these components by increasing material thickness, thus extending their lifespan. The rectangular cross-section, compared to other shapes (such as circles), distributes heat more effectively and offers better mechanical strength, allowing the thickened section 5 to maintain good insulation performance and mechanical stability even under prolonged high-temperature conditions.

[0037] In summary, this invention solves the problems of performance degradation and aging of sealing materials at the front end of the motor inside the oven caused by the high-temperature working environment.
