Description

Technical Field

[0001] This utility model relates to an encoder fixing structure for a telescopic knob. Background Technology

[0002] Currently, the telescopic knobs for electric ovens available on the market and in published materials consist of a knob and a housing. The main body of the telescopic knob is exposed outside the oven. The housing has slots or clips that match the thickness of the main panel, thus fixing the telescopic knob to the main panel. A circuit board is fixed inside the housing of the telescopic knob, and the circuit board has an encoder. Currently, the circuit board is usually fixed to the housing by a bracket. This structure has the following drawbacks: after the circuit board is fixed by the bracket, the encoder of the circuit board is directly exposed outside the housing, making it easy for dust to get in. Furthermore, since the circuit board is fixed by the bracket, the fixation between the circuit board and the housing is not tight enough, and the circuit board is prone to loosening after long-term use. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an encoder fixing structure for a telescopic knob, effectively solving the issues mentioned in the background art.

[0004] The technical solution adopted in this utility model is:

[0005] An encoder fixing structure for a telescopic knob includes a housing, an encoder placement area is provided at the bottom of the housing, and a screw hole is provided on each side of the encoder placement area at the bottom of the housing.

[0006] Preferably, the bottom of the housing has a downwardly protruding positioning post fixed on each side of the encoder placement area.

[0007] The positioning pins are used to position the circuit board on which the encoder is installed, so that the screw holes can be aligned with the holes on the circuit board, making it easier to insert the screws into the screw holes.

[0008] Preferably, the encoder placement area has a base plate on the side facing the top of the housing. The base plate is fixedly connected to the bottom of the housing through connecting plates on both sides, and a rotating shaft hole is provided in the middle of the base plate.

[0009] The base plate is designed to protect the encoder from the top, preventing accidental damage. The base plate has a shaft hole in the middle that matches the shaft on the encoder, allowing the shaft to extend from the bottom of the housing into the housing.

[0010] Preferably, the side of the encoder placement area has a through hole between the two connecting plates.

[0011] Since the encoder is placed in the encoder placement area, the bottom opening of the encoder placement area is basically closed by the circuit board, which is not conducive to the heat dissipation of the encoder. By setting through holes, the encoder placement area is connected to the inside of the housing, thereby increasing the space connected to the encoder placement area and facilitating the heat dissipation of the encoder.

[0012] Preferably, the base plate and connecting plate are integrally formed with the shell.

[0013] The base plate, connecting plate, and shell are integrally molded, which can improve the connection strength and simplify the assembly process, making production easier.

[0014] This invention features an encoder placement area on the bottom outer side of the housing. This allows the encoder to be placed precisely within the encoder placement area when the circuit board is directly fixed to the bottom of the housing, thus achieving a tight fit between the encoder and the housing. Furthermore, since the encoder is located within the encoder placement area, external dust and other debris are less likely to enter and damage the encoder, extending its service life.

[0015] After an encoder is installed at the bottom of the housing, this invention can be used in various household appliances, such as ovens, microwave ovens, and integrated stoves. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] Furthermore, in the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0024] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0025] like Figure 1-2As shown, a telescopic knob encoder fixing structure includes a housing 1. The bottom of the housing 1 has an encoder placement area 2 for placing the encoder. The bottom of the housing 1 has a screw hole 3 on each side of the encoder placement area 2 for fixing the circuit board on which the encoder is installed.

[0026] The bottom of the housing 1 has a downwardly protruding positioning post 4 fixed on each side of the encoder placement area 2. The positioning post 4 is used to position the circuit board on which the encoder is installed, so that the screw hole 3 can be aligned with the hole on the circuit board, making it easy to insert the screw into the screw hole 3.

[0027] The encoder placement area 2 has a base plate 5 on the side facing the top of the housing 1. The base plate 5 is fixedly connected to the bottom of the housing 1 through connecting plates 6 on both sides. The base plate 5 can protect the encoder from the top and prevent accidental damage to the encoder from the top. The center of the base plate 5 has a rotating shaft hole 7, which matches the rotating shaft on the encoder, so that the rotating shaft on the encoder can extend into the housing 1 from the bottom.

[0028] The encoder placement area 2 has a through hole 8 on its side between the two connecting plates 6. Since the encoder is placed in the encoder placement area 2, the bottom opening of the encoder placement area 2 is basically closed by the circuit board, which is not conducive to the heat dissipation of the encoder. By setting the through hole 8, the encoder placement area 2 is connected to the inside of the housing 1, thereby increasing the space connected to the encoder placement area 2 and facilitating the heat dissipation of the encoder.

[0029] The base plate 5 and connecting plate 6 are integrally formed with the shell 1, which can improve the connection strength and simplify the assembly process, making it easier to produce.

[0030] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
