Description
Technical Field
[0001] This application relates to the technical field of water retaining rings, and particularly to an upper water retaining ring. Background Art
[0002] The upper water retaining ring is an important accessory in a steam oven. Generally, a steam oven is provided with a fan system to circulate the air or steam in its inner cavity. The fan system usually includes a fan blade and a motor for driving the fan blade to rotate. The motor shaft extends into the inner cavity of the steam oven. An oil-containing bearing for providing lubricating oil for the rotation of the motor shaft is arranged on the motor shaft. To prevent the water vapor in the inner cavity of the steam oven from liquefying and contacting the oil-containing bearing, causing the bearing to rust, a T-shaped groove is opened on the aluminum front bracket. A water retaining ring is installed in the T-shaped groove. The motor shaft passes through the water retaining ring, and then a gasket is riveted on one side of the water retaining ring. The water retaining ring is located between the gasket and the bearing. The outer circumferential surface of the gasket fits against the inner wall of the upper groove of the T-shaped groove, and the outer circumferential surface of the water retaining ring fits against the groove wall of the lower groove of the T-shaped groove. When the steam oven is in use, the gasket and the water retaining ring can block the liquefied water vapor, thereby reducing the possibility of the liquefied water vapor contacting the oil-containing bearing and improving the service life of the bearing. However, during the rotation of the motor shaft, the motor shaft is likely to swing and shake under the action of the fan blade, resulting in a gap between the gasket and the water retaining ring. As a result, the liquefied water vapor enters the T-shaped groove through the gap between the gasket and the water retaining ring, and further increases the possibility of the liquefied water vapor contacting the bearing through the T-shaped groove, and the service life of the bearing is low. Summary of the Utility Model
[0003] In order to improve the service life of the bearing, this application provides an upper water retaining ring.
[0004] An upper water retaining ring provided by this application adopts the following technical solution:
[0005] An upper water retaining ring includes a fitting part and a water retaining part. One end of the fitting part is connected to one end of the water retaining part, and the fitting part and the water retaining part are integrally formed. An elastic part is connected to the end of the water retaining part away from the fitting part. When the elastic part is installed in the T-shaped groove, the end of the elastic part away from the water retaining part fits against the groove wall of the T-shaped groove.
[0006] By adopting the above technical solution, when the upper water retaining ring needs to be installed, the upper water retaining ring is installed in the T-shaped groove, the cushioning part is attached to the gasket, and the end of the elastic part far from the water retaining part is attached to the groove wall of the T-shaped groove far from the gasket. When the motor shaft sways, the elastic part provides a swaying range for the swaying of the upper water retaining ring, so that the elastic part is closely attached to the groove wall of the T-shaped groove, and the elastic part and the groove wall of the T-shaped groove will not be separated. At the same time, under the influence of the elastic function of the elastic part, the elastic part pushes the cushioning part to fit the gasket through the water retaining part, reducing the possibility of separation between the gasket and the cushioning part, and further reducing the possibility that the liquefied water vapor enters the T-shaped groove through the gap generated by the separation of the gasket and the cushioning part, thereby reducing the possibility of contact with the bearing through the T-shaped groove, and improving the service life of the bearing.
[0007] Optionally, the elastic part includes a first folding piece and a second folding piece. The first folding piece is connected to the second folding piece. The connection end of the first folding piece and the second folding piece is the folding end. One end of the first folding piece far from the second folding piece is connected to the water retaining part. When the first folding piece and the second folding piece are installed in the T-shaped groove, the end of the second folding piece far from the first folding piece is attached to the groove wall of the T-shaped groove.
[0008] By adopting the above technical solution, when the motor shaft sways, the second folding piece is attached to the groove wall of the T-shaped groove, and the first folding piece and the second folding piece are folded at the folding end, thus forming an elastic support. The first folding piece supports the water retaining part, so that the cushioning part is closely attached to the gasket, and further reduces the possibility of the liquefied water vapor contacting the bearing.
[0009] Optionally, the thickness of the first folding piece and the thickness of the second folding piece are both smaller than the thickness of the water retaining part.
[0010] By adopting the above technical solution, making the thicknesses of the first folding piece and the second folding piece smaller than the thickness of the water retaining part facilitates the folding of the first folding piece and the second folding piece. Thus, when the motor shaft sways, the first folding piece can be stably folded through the folding end, improving the stability of the elastic part.
[0011] Optionally, the first folding piece is provided with a first folding groove, and the second folding piece is provided with a second folding groove. Both the first folding groove and the second folding groove are located at the folding end, and the first folding groove and the second folding groove form the folding groove of the first folding piece and the second folding piece.
[0012] By adopting the above technical solution, the first folding piece and the second folding piece are folded through the folding groove, so that the first folding piece and the second folding piece are stably folded, reducing the possibility of the folding direction of the first folding piece deviating when the first folding piece and the second folding piece are folded, and further improving the folding stability of the first folding piece.
[0013] Optionally, the first folding member is in an eight-character ring shape, the second folding member is in an eight-character ring shape, the end with a small opening of the first folding member is connected to the water blocking portion, and the end of the first folding member away from the water blocking portion is connected to the end with a large opening of the second folding member.
[0014] By adopting the above technical solution, when the first folding member needs to be folded, the folding ends of the first folding member and the second folding member extend outwards, reducing the possibility of the folding ends of the first folding member and the second folding member colliding with the motor shaft during folding, reducing the damage of the motor shaft, and at the same time improving the folding stability of the first folding member and the second folding member.
[0015] Optionally, the first folding member and the second folding member are integrally formed.
[0016] By adopting the above technical solution, the upper water blocking ring is installed on the motor shaft. If the first folding member and the second folding member are separated, when the first folding member and the second folding member are folded for a long time, the first folding member and the second folding member are likely to break, resulting in the damage of the upper water blocking ring. When the upper water blocking ring needs to be replaced, parts such as the blower, motor, and gasket need to be removed, increasing the maintenance difficulty of the steam oven. The first folding member and the second folding member are integrally formed, making the first folding member and the second folding member an integral structure, thereby reducing the possibility of the first folding member and the second folding member breaking and separating, reducing the maintenance difficulty of the steam oven, and at the same time improving the folding stability of the first folding member and the second folding member.
[0017] Optionally, the water blocking portion includes a water blocking member and a protruding member. The outer wall of the water blocking member is connected to the inner wall of the protruding member. The outer wall of the cushioning portion protrudes from the outer wall of the water blocking member. The water blocking member forms a lower groove between the protruding member and the cushioning portion, and the lower groove is used to position the position of the snap ring.
[0018] By adopting the above technical solution, when the upper water blocking ring needs to be fixed, the snap ring is arranged at the lower groove to position the position of the snap ring, reducing the possibility of the snap ring shifting during installation, improving the installation tightness of the snap ring, and further improving the installation stability of the upper water blocking ring.
[0019] Optionally, a limiting member is connected to the side of the protruding member close to the cushioning portion, and the limiting member is located at the end of the protruding member away from the water blocking member.
[0020] By adopting the above technical solution, when the snap ring is installed, the side of the snap ring away from the groove wall of the lower groove abuts against the limiting member, thereby further limiting the position of the snap ring, fixing the installation position of the snap ring, and by providing the limiting member, it is convenient to visually understand the clamping state of the snap ring. When the snap ring is installed, it is known whether the snap ring is fastened by observing whether the limiting member is convex, thereby improving the installation stability of the upper water blocking ring.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. When the upper water retaining ring needs to be installed, the upper water retaining ring is installed in the T-shaped groove, the cushioning portion is attached to the gasket, and the end of the elastic portion away from the water retaining portion is attached to the groove wall of the T-shaped groove away from the gasket. When the motor shaft sways and shakes, the elastic member provides a shaking interval for the shaking of the upper water retaining ring, so that the elastic portion closely adheres to the groove wall of the T-shaped groove, and the elastic portion and the groove wall of the T-shaped groove will not be separated. At the same time, under the influence of the elastic function of the elastic portion, the elastic member pushes the cushioning portion to fit against the gasket through the water retaining portion, reducing the possibility of separation between the gasket and the cushioning portion, and further reducing the possibility that the liquefied water vapor enters the T-shaped groove through the gap generated by the separation between the gasket and the cushioning portion, thereby reducing the possibility of contacting the bearing through the T-shaped groove and improving the service life of the bearing;
[0023] 2. When the motor shaft shakes, the second folding member is attached to the groove wall of the T-shaped groove, and the first folding member and the second folding member are folded at the folding end, thereby forming an elastic support. The first folding member supports the water retaining portion, so that the cushioning portion closely adheres to the gasket, thereby reducing the possibility that the liquefied water vapor contacts the bearing;
[0024] 3. When the first folding member needs to be folded, the folding ends of the first folding member and the second folding member extend outwards, reducing the possibility that the folding ends of the first folding member and the second folding member collide with the motor shaft during folding, reducing the damage of the motor shaft, and at the same time improving the folding stability of the first folding member and the second folding member.

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.
[0031] An embodiment of the present application discloses an upper water retaining ring.
[0032] Reference Figure 1 and Figure 2 , a top water retaining ring, comprising a fitting part 1 and a water retaining part 2. The fitting part 1 is annular, the water retaining part 2 is annular, one end of the fitting part 1 is fixedly connected to one end of the water retaining part 2, and the fitting part 1 and the water retaining part 2 are integrally formed. An elastic part 3 is fixedly connected to the end of the water retaining part 2 away from the fitting part 1. The fitting part 1, the water retaining part 2 and the elastic part 3 are integrally formed. The elastic part 3 is annular. The centers of the rings of the fitting part 1, the water retaining part 2 and the elastic part 3 are on the same straight line, forming an installation opening 4 for the motor shaft to penetrate. When the elastic part 3 is installed in the T-shaped groove, the end of the elastic part 3 away from the water retaining part 2 fits against the groove wall of the T-shaped groove.
[0033] When installing the top water retaining ring, insert the motor shaft into the installation opening 4. The motor shaft abuts against the inner walls of the fitting part 1, the water retaining part 2 and the elastic part 3, so that the top water retaining ring is sleeved on the motor shaft. Then install the top water retaining ring in the T-shaped groove. The fitting part 1 is attached to the gasket, and the fitting part 1 is riveted to the gasket. The end of the elastic part 3 away from the water retaining part 2 is attached to the groove wall of the T-shaped groove away from the gasket. When the motor shaft sways, the elastic part provides a shaking interval for the top water retaining ring, so that the elastic part 3 tightly adheres to the groove wall of the T-shaped groove, and the elastic part 3 and the groove wall of the T-shaped groove will not separate. At the same time, under the influence of the elastic function of the elastic part 3, the elastic part pushes the fitting part 1 to fit against the gasket through the water retaining part 2, reducing the possibility of the separation between the gasket and the fitting part 1, and further reducing the possibility of the liquefied water vapor entering the T-shaped groove through the gap generated by the separation between the gasket and the fitting part 1, thereby reducing the possibility of contacting the bearing through the T-shaped groove and improving the service life of the bearing.
[0034] Specifically, the elastic part 3 includes a first folding part 31 and a second folding part 32. The first folding part 31 is in an eight-shaped ring, and the second folding part 32 is in an eight-shaped ring. The end with a small opening of the first folding part 31 is fixedly connected to the end of the water retaining part 2 away from the fitting part 1. The end of the first folding part 31 away from the water retaining part 2 is fixedly connected to the end with a large opening of the second folding part 32. The connection end of the first folding part 31 and the second folding part 32 is the folding end. When the top water retaining ring is installed in the T-shaped groove, when the first folding part 31 and the second folding part 32 are installed in the T-shaped groove, the inner wall of the end of the first folding part 31 away from the second folding part 32 abuts against the motor shaft, the inner wall of the end of the second folding part 32 away from the first folding part 31 abuts against the motor shaft, and the outer wall of the end of the second folding part 32 away from the first folding part 31 fits against the groove wall of the T-shaped groove.
[0035] When the motor shaft shakes, the second folding part 32 adheres to the groove wall of the T-shaped groove, and the first folding part 31 and the second folding part 32 are folded at the folding end, and the first folding part 31 and the second folding part 32 extend outwards, thereby forming an elastic support for the water retaining part 2, making the fitting part 1 closely adhere to the gasket, and further reducing the possibility of the liquefied water vapor contacting the bearing.
[0036] To improve the folding smoothness and stability of the first folding member 31 and the second folding member 32, the thicknesses of both the first folding member 31 and the second folding member 32 are smaller than the thickness of the water blocking portion 2, facilitating the folding of the first folding member 31 and the second folding member 32.
[0037] Refer to Figure 2 and Figure 3 As shown in, a first folding groove 311 is provided on the inner wall of the first folding member 31, such that one end of the first folding member 31 close to the second folding member 32 is beveled. A second folding groove 321 is provided on the inner wall of the second folding member 32, such that one end of the second folding member 32 close to the first folding member 31 is beveled. The first folding groove 311 and the second folding groove 321 are in communication with each other. Both the first folding groove 311 and the second folding groove 321 are located at the folding end, and the first folding groove 311 and the second folding groove 321 form a folding groove for the first folding member 31 and the second folding member 32.
[0038] When the first folding member 31 and the second folding member 32 are folded, the first folding member 31 and the second folding member 32 can be folded through the folding groove, so that the first folding member 31 and the second folding member 32 are stably folded under the guidance of the folding groove, reducing the possibility of the folding direction of the first folding member 31 deviating when the first folding member 31 and the second folding member 32 are folded, and thus improving the folding stability of the first folding member 31.
[0039] To reduce the possibility of the first folding member 31 and the second folding member 32 breaking and further improve the elastic stability of the first folding member 31 and the second folding member 32, when the first folding member 31 and the second folding member 32 are produced, an integral molding process is used to integrally form the first folding member 31 and the second folding member 32.
[0040] The water blocking portion 2 includes a water blocking member 21 and a protruding member 22. The water blocking member 21 is annular, and the protruding member 22 is annular. The protruding member 22 is sleeved on the water blocking member 21. The outer wall of the water blocking member 21 is fixedly connected to the inner wall of the protruding member 22, so that the protruding member 22 protrudes on the outer wall of the water blocking member 21. One end of the water blocking member 21 is fixedly connected to one side of the cushioning portion 1, and the side of the water blocking member 21 away from the cushioning portion 1 is fixedly connected to the first folding member 31. The outer wall of the cushioning portion 1 protrudes from the outer wall of the water blocking member 21, so that the outer walls of both the cushioning portion 1 and the protruding portion protrude from the outer wall of the water blocking member 21. The water blocking member 21 forms a lower groove 5 between the protruding member 22 and the cushioning portion 1, and the lower groove 5 is used to position the position of the snap ring.
[0041] When fixing the upper water blocking ring, the snap ring is clamped at the lower groove 5 to position the position of the snap ring, reducing the possibility of the snap ring shifting during installation, improving the installation tightness of the snap ring, and thus improving the installation stability of the upper water blocking ring.
[0042] One side of the convex member 22 close to the cushioning portion 1 is fixedly connected with a limiting member 6. The limiting member 6 is annular and is located at one end of the convex member 22 away from the water blocking member 21.
[0043] When installing the circlip, one side of the circlip away from the groove wall of the lower groove 5 abuts against the limiting member 6, so as to further limit the position of the circlip, fix the installation position of the circlip, and by setting the limiting member 6, it is convenient to intuitively understand the clamping state of the circlip. When installing the circlip, it can be known whether the circlip is fastened by observing whether the limiting member 6 is convex, thereby improving the installation stability of the upper water retaining ring.
[0044] The implementation principle of an upper water retaining ring in an embodiment of the present application is as follows: when the motor shaft sways and shakes, the folding function of the first folding member 31 and the second folding member 32 provides a shaking interval for the shaking of the upper water retaining ring, so that the second folding member 32 closely adheres to the groove wall of the T-shaped groove, and the second folding member 32 and the groove wall of the T-shaped groove will not be separated. At the same time, under the influence of the elastic function generated by the folding relationship between the first folding member 31 and the second folding member 32, the first folding member 31 pushes the cushioning portion 1 to fit against the gasket through the water blocking portion 2, reducing the possibility of separation between the gasket and the cushioning portion 1, and further reducing the possibility of liquefied water vapor entering the T-shaped groove through the gap generated by the separation between the gasket and the cushioning portion 1, thereby reducing the possibility of contacting the bearing through the T-shaped groove, and improving the service life of the bearing.
[0045] The above are all preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
