[0002] The existing cross-flow fans are mainly used in equipment such as fireplaces, air conditioners, cooling equipment, and ventilation equipment to achieve a stronger air outlet effect. Compared with ordinary fans, the air outlet effect is stronger and better. However, the existing cross-flow fans do not well consider how to better connect and set on household appliances during actual use, resulting in a relatively complex connection and fixing structure and a relatively large occupied volume. Therefore, a stable and reliable fan for household appliances with a simple structure and easier connection to external structures is needed. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a stable and reliable fan for household appliances with a simple structure and easier connection to external structures.

[0004] The utility model provides a stable and reliable fan for household appliances, including a fan body and a shaded-pole motor. The shaded-pole motor is arranged on the side of the fan body and fixedly connected to the fan body.

[0005] The fan body includes a fan housing and an impeller. One end of the impeller is fixedly connected to the output shaft of the shaded-pole motor, so that the impeller can be driven to rotate by the shaded-pole motor.

[0006] Three connecting grooves are arranged at the bottom of the fan housing. A plurality of first connecting holes are arranged in the connecting grooves, and the connecting grooves on both sides are L-shaped. By arranging the connecting grooves and the first connecting holes, the fan housing can be better connected to external structures.

[0007] Preferably, through holes for connecting the housing are arranged on both sides of the fan housing. Both ends of the impeller are rotatably connected to the through holes for connecting the housing and are arranged inside the fan housing.

[0008] Preferably, a plurality of second connecting holes are arranged around the outside of the through holes for connecting the housing. A shaded-pole motor bracket is arranged on the shaded-pole motor, and a through hole of the bracket is arranged on the shaded-pole motor bracket. The shaded-pole motor is fixedly connected to the fan body by screwing the through hole of the bracket and the second connecting holes.

[0009] Preferably, an air outlet of the fan housing is arranged on the front side of the fan housing. A plurality of third connecting holes are arranged on both sides opposite to the air outlet of the fan housing. By arranging the third connecting holes, the fan housing can be more tightly connected to external structures and the air outlet effect can be better when the fan housing is connected to external structures.

[0010] Preferably, the blower housing at the top of the air outlet of the blower housing bends upward, thereby forming a conical air outlet duct within the blower housing. By providing the conical air outlet duct, the air outlet effect of the blower body can be improved.

[0011] The beneficial effects of the stable and reliable household appliance blower of the present utility model are as follows:

[0012] 1. By providing the connection groove and the first connection hole, the blower housing can be better connected to the external structure.

[0013] 2. By providing the bracket through-hole and the second connection hole, the shaded-pole motor can be better fixedly connected to the blower body.

[0014] 3. By providing the third connection hole, when the blower housing is connected to the external structure, it can be more tightly connected and the air outlet effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The realization, functional features and advantages of the object of the present utility model will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Refer to Figure 1 、 Figure 2 and Figure 3 to present an embodiment of the stable and reliable household appliance blower of the present utility model:

[0022] A stable and reliable household appliance blower includes a blower body 2 and a shaded-pole motor 1.

[0023] The fan body 2 includes a fan housing 21 and an impeller 22. Through holes for housing connection are provided on both sides of the fan housing 21. Both ends of the impeller 22 are rotatably connected to the through holes for housing connection and are arranged inside the fan housing 21. An air outlet of the fan housing is provided on the front side of the fan housing 21. The fan housing 21 above the air outlet of the fan housing bends upward, so as to form a conical air outlet duct 215 inside the fan housing 21. By providing the conical air outlet duct 215, the air outlet effect of the fan body can be improved.

[0024] A plurality of second connection holes 213 are circumferentially arranged outside the through holes for housing connection. A shaded-pole motor bracket is provided on the shaded-pole motor 1, and a through hole for the bracket is provided on the shaded-pole motor bracket. The shaded-pole motor 1 and the fan body 2 are fixedly connected by screwing the through hole for the bracket and the second connection holes 213. One end of the impeller 22 is fixedly connected to the output shaft of the shaded-pole motor 1, so that the impeller 22 can be driven to rotate by the shaded-pole motor 1.

[0025] Three connection grooves 211 are provided at the bottom of the fan housing 21, and three first connection holes 212 are provided in the connection grooves 211. The middle connection groove 211 is strip-shaped, and the two connection grooves 211 on both sides are L-shaped and arranged oppositely. The three first connection holes 212 of the middle strip-shaped connection groove 211 are respectively arranged in the middle and on both sides, and the three first connection holes 212 of the L-shaped connection groove 211 are respectively arranged in the middle and at the ends of the two folded edges. By providing the connection grooves 211 and the first connection holes 212, the fan housing 21 can be better connected to the external structure.

[0026] Four third connection holes 213 are provided on both sides opposite to the air outlet of the fan housing. The third connection hole 213 at the top is relatively large, and the three third connection holes 213 at the lower side are relatively small. By providing the third connection holes 213, the fan housing 21 can be more tightly connected to the external structure and the air outlet effect can be better. By providing third connection holes 213 with different sizes, the installation requirements of different external structures can be met.

[0027] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
