Abstract
Description
Technical Field
[0001] This utility model relates to motor technology, and more specifically, to a household motor. Background Technology
[0002] An electric motor is a device that converts electrical energy into mechanical energy, which makes it widely used in people's daily lives. An electric motor consists of a housing, a stator, and a rotor. The stator is fixedly installed inside the housing, while the rotor is placed inside the stator. Usually, a label is affixed to the outer surface of the housing to display parameters such as the motor's circuit diagram.
[0003] In real life, kitchen appliances such as range hoods contain motors. The motor housing can be divided into an upper housing and a lower housing, which are fixed together by bolts. During the long-term use of the range hood, when the motor malfunctions, people need to repair it. During repair, people need to read the parameters on the label.
[0004] However, due to the working environment of range hoods, the parameters on the labels are easily covered by grease and other contaminants, making it difficult for people to read the parameters. People also need to clean the grease off the labels, which is quite inconvenient.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a household motor.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a household motor, including an upper shell and a lower shell detachably connected to the upper shell, an identification plate is affixed to the outer wall of the upper shell, a fixing ring is formed on both the upper shell and the lower shell, a fixing ring through which a bolt can pass is formed, a cover plate for covering the identification plate is detachably connected to the fixing ring, a fixing member for limiting one end of the cover plate is formed on the outer wall of the upper shell, and the other end of the cover plate can be installed on the fixing ring.
[0008] The present invention is further configured such that: the upper shell has a groove for accommodating the signboard, the cover plate includes a vertical piece covering the groove and a horizontal piece arranged perpendicular to the vertical piece, and the horizontal piece has a round hole for a bolt to pass through.
[0009] The present invention is further configured such that: a slot is provided on the vertical piece, and the fixing member includes a base fixed to the upper shell and a limiting part that can pass through the slot, and an angle is formed between the limiting part and the base.
[0010] The present invention is further configured such that the distance from the end of the limiting part away from the base to the outer wall of the upper shell is greater than the distance from the connection point of the limiting part and the base to the outer wall of the upper shell.
[0011] The present invention is further configured such that the thickness at the connection between the limiting part and the base is greater than the thickness of the end of the limiting part away from the base.
[0012] The present invention is further configured such that all corners of the mask are rounded.
[0013] The present invention is further configured such that the shield is made of a thin copper alloy sheet.
[0014] In summary, this utility model has the following beneficial effects: When the motor of the range hood malfunctions and needs repair, the motor can be removed from the range hood. When it is necessary to read the relevant parameters of the motor, the shield on the fixing ring can be removed, and then the parameters on the label can be checked. The motor can be repaired according to the parameters. The shield is designed so that when the motor is running normally, the oil fumes extracted by the range hood can be effectively separated from the label when passing through the upper shell. This makes it easier for people to check the parameters on the label, as the oil fumes are not easily adhered by the oil stains in the oil fumes. The anti-vibration pads fitted on the bolts can reduce the possibility of the bolts being loosened due to the vibration of the motor, thereby improving the sealing of the upper and lower shells and enabling the motor to adapt better to the working environment full of oil fumes.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] A type of household motor, such as Figure 1 and Figure 2As shown, the device includes an upper shell 1 and a lower shell 2 detachably connected to the upper shell 1. An identification plate 3 is affixed to the outer wall of the upper shell 1. Both the upper shell 1 and the lower shell 2 have retaining rings 5 through which bolts 4 can pass. Two anti-vibration pads are fitted onto the bolts 4, respectively contacting the upper shell 1 and the lower shell 2. The anti-vibration pads increase the contact area between the bolts 4 and the upper shell 1 or lower shell 2, thereby increasing the friction between the threads 4 and the upper shell 1 or lower shell 2. This prevents the motor from loosening due to operational vibrations and ensures the seal between the upper shell 1 and the lower shell 2. A cover plate for covering the identification plate 3 is detachably connected to the retaining ring 5. A fixing member for limiting one end of the cover plate is formed on the outer wall of the upper shell 1. The other end of the shield can be installed on the fixing ring 5. When the range hood motor malfunctions and needs repair, the motor is first removed from the range hood. When it is necessary to read the relevant parameters of the motor, the shield on the fixing ring 5 can be removed, and then the parameters on the label 3 can be checked. The motor can then be repaired based on the parameters. The shield is designed so that when the motor is running normally, the oil fumes extracted by the range hood pass through the upper shell 1, and the shield can effectively separate the oil fumes from the label 3. This makes it easier for people to check the parameters on the label 3 without the oil stains in the oil fumes adhering to them. The upper shell 1 has a groove 6 for accommodating the label 3. The shield includes a vertical piece 7 covering the groove 6 and a horizontal piece 8 perpendicular to the vertical piece 7. The horizontal piece 8 has a circular hole 9 for a bolt 4 to pass through. One of the bolts 4 passing through the circular hole 9 has an anti-vibration washer that abuts against the horizontal piece 8. During motor production, the production staff affixes a label 3 indicating the motor parameters to the side wall of the groove 6, attaches the upper shell 1 and lower shell 2 together, and covers the groove 6 with the shield. Then, the bolt 4 is passed through the circular hole 9 and two retaining rings 5 and tightened to completely fix the shield, upper shell 1, and lower shell 2. The circular hole 9 allows the bolt 4 to pass through the horizontal piece 8 and fix the shield to the upper shell 1. During motor use... The cover plate is not easily separated from the upper shell 1. At the same time, when the motor needs maintenance, people will loosen the bolts 4 that fix the upper shell 1 and the lower shell 2. During the process of loosening the bolts 4, the bolts 4 lose their limiting effect on the cover plate, so that people can remove the cover plate from the upper shell 1 at the same time as disassembling the upper shell 1 and the lower shell 2. The setting of the groove 6 allows the sign 3 to be well accommodated in the groove 6. When the vertical piece 7 covers the groove 6, the sign 3 located in the groove 6 can be well protected by the cover plate. In addition, the opening of the groove 6 can also play a certain guiding role when production personnel affix the sign 3, so that production personnel can affix the sign 3 according to the position of the groove 6.
[0021] like Figure 2 and Figure 3As shown, a slot 10 is provided on the vertical piece 7. The fixing component includes a base 11 fixed to the upper shell 1 and a limiting part 12 that can pass through the slot 10. An angle is formed between the limiting part 12 and the base 11. The distance between the connection between the limiting part 12 and the base 11 is equal to the thickness of the cover plate. After the motor is repaired, the limiting part 12 and the base 11 are passed through the slot 10 in sequence, so that the horizontal piece 8 is attached to the fixing ring 5 of the upper shell 1. Then the upper shell 1 and the lower shell 2 are attached and bolts 4 are used to completely fix the upper shell 1 and the lower shell 2. At this time, the horizontal piece 8 is fixed by the bolts 4, and the vertical piece 7 is limited by the fixing component, so that the cover plate is not easy to move during the use of the motor, thus ensuring better protection of the sign plate 3 by the cover plate. The end of the limiting part 12 away from the base 11 extends to the outside of the upper shell 1. The distance between the wall and the limit part 12 is greater than the distance from the connection between the limit part 12 and the base 11 to the outer wall of the upper shell 1. This arrangement makes the distance between the end of the limit part 12 away from the base 11 and the outer wall of the upper shell 1 larger. After the motor is repaired, during the installation of the cover, people can easily pass the limit part 12 through the slot 10. The thickness at the connection between the limit part 12 and the base 11 is greater than the thickness of the end of the limit part 12 away from the base 11. This arrangement makes the end of the limit part 12 away from the base 11 thinner. Therefore, when people pass the limit part 12 through the slot 10, the projected area of the end of the limit part 12 away from the base 11 is smaller, and it can pass through the slot 10 more easily. This way, people do not need to spend a lot of time passing the limit part 12 through the slot 10.
[0022] like Figure 1 As shown, all edges and corners of the cover are rounded. The rounded corners make the edges of the cover less sharp, so that the cover is less likely to cause injury to people's hands when they are disassembling or installing it. The cover is made of copper alloy sheet. Copper alloy has good corrosion resistance, so the cover made of copper alloy can adapt well to the working environment inside the range hood, thus enabling the cover to play a better protective role for the sign 3.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
