Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a cooling fan for an induction cooker. Background Technology

[0002] Existing induction cookers have relatively higher power, and in order to ensure sufficient heat dissipation performance, the internal space is also large enough, ensuring sufficient cavity for heat dissipation. This also makes the requirements for the cooling fan less demanding, and the overall size of the cooling fan is relatively large.

[0003] The applicant recently designed a foldable induction cooker. If traditional induction cooker design specifications are used, the overall thickness after folding would be too large, making it inconvenient to use, pack, and transport. Therefore, the thickness of the induction cooker on one side is required. This places higher demands on the design of the cooling fan, requiring a reduction in fan size without significantly compromising cooling efficiency. Therefore, a simple, relatively low-profile, and relatively powerful cooling fan for the induction cooker is needed. Utility Model Content

[0004] The main purpose of this invention is to provide an induction cooker cooling fan that has a simple structure, relatively low height, and relatively strong heat dissipation capacity.

[0005] This utility model proposes an induction cooker cooling fan, including a fan housing, a fan body, a limiting connector, a rotor, and a stator;

[0006] The fan housing includes a base and a top cover. The top cover is disposed on the top of the base and fixedly connected to the base. A base through hole is provided in the middle of the bottom of the base. The edge of the base through hole extends upward to form a base connecting post. The stator is wound around the outside of the base connecting post and fixedly connected to the base.

[0007] The bottom of the fan body is provided with a body connecting post that is adapted to the through hole of the base. The bottom of the body connecting post is provided with a body connecting post through hole. The body connecting post is disposed in the through hole of the base and connected to the limiting connector, thereby allowing the fan body to be rotatably connected to the inner side of the fan housing.

[0008] The rotor is annular and surrounds the outside of the stator and is fixedly connected to the inner side of the top of the fan housing. By energizing the stator, the rotor can be driven to rotate, thereby driving the fan body to rotate.

[0009] Preferably, the base is provided with a base connection hole, and the stator is fixedly connected to the base by means of screws connected to the base connection hole.

[0010] Preferably, the fan body includes a rotating body component, multiple fan blades, and an outer connecting ring. A body connecting platform is provided on the side of the rotating body component. One end of the fan blade is fixedly connected to the body connecting platform, and the other end of the fan blade is fixedly connected to the outer connecting ring.

[0011] Preferably, the base has multiple base connecting buckles on its side and the top cover has multiple top cover connecting blocks. The top cover is secured to the base by the cooperation of the base connecting buckles and the top cover connecting blocks.

[0012] Preferably, the upper cover is provided with a positioning slot on the side of the upper cover, and the base and the upper cover are provided with a fixing hole and a fixing hole on the side opposite to the positioning slot of the upper cover;

[0013] The bottom of the induction cooker housing is provided with a housing positioning block and a housing fixing hole. The housing positioning block and the upper cover positioning slot cooperate to fix one end of the fan housing to the induction cooker housing. The other end of the fan housing is fixedly connected to the induction cooker housing by screws connecting the base fixing hole, the upper cover fixing hole and the housing fixing hole.

[0014] Preferably, the base includes a base body and a base connecting platform disposed in the middle of the base body. The base body and the base connecting platform are connected by connecting arms, and multiple base air inlets are provided between the connecting arms.

[0015] Preferably, the base body has a base through hole at the bottom and the connecting arm has a connecting arm connecting groove at the bottom, and the external line is electrically connected to the stator after passing through the connecting arm connecting groove and the base through hole.

[0016] Preferably, the connecting arm connecting groove is provided with a connecting arm connecting groove through hole, and a connecting arm limiting block is provided on the side of the connecting arm connecting groove corresponding to the connecting arm connecting groove through hole. The external line is limited and fixed by the cooperation of the connecting arm limiting block and the connecting arm connecting groove through hole.

[0017] The beneficial effects of the induction cooker cooling fan of this utility model are as follows:

[0018] 1. By adopting an external rotor fan design, the overall size of the fan can be reduced and the connection structure can be relatively simple.

[0019] 2. By setting a connecting arm slot on the connecting arm, space can be compressed as much as possible, thereby reducing the overall height of the fan.

[0020] 3. The fan blades are relatively long, which can maintain a certain heat dissipation effect while reducing the height. Attached Figure Description
