Description

Technical Field

[0001] The invention belongs to the technical field of tower fans, and in particular relates to a tower fan motor wiring connection structure and a tower fan thereof. Background Art

[0002] Tower fans form a three-dimensional exchange system between indoor and outdoor air based on the principle of airflow. Tower fans usually "throw" the wind out through a crossflow fan to form an airflow, that is, the wind pressure is generated by the rotation of the wind wheel to generate centrifugal wind force, and finally the wind force is transmitted out through the internal wind guide wall. Since the crossflow wind wheel is generally cylindrical, the use of a tower fan obtains a three-dimensional airflow wall or wind curtain, which is perpendicular to the ground and swings left and right to blow. The crossflow wind wheel has many blades, and the air supply is uniform and soft, which is very close to natural wind. Tower fans are used in conjunction with air conditioners to form an air circulation, which is suitable for families with elderly people and children. Its 360-degree all-round air supply leaves the room with no dead corners for air supply, making people feel comfortable.

[0003] At present, for the inner-rotating tower fans on the market, in order to effectively utilize the internal space of the tower fan, the motor is hidden inside the air duct assembly. The rotor of the motor of the inner-rotating tower fan is usually exposed to the outside, and the motor wiring is easy to contact the rotor of the tower fan motor. Therefore, for the existing tower fans, on the one hand, because the motor is set inside the air duct assembly, when working normally, the rotor of the motor is exposed without stator protection. When the rotor runs at high speed, the rotor is easy to touch the motor wiring, causing damage or breakage of the motor wiring; on the other hand, when the air duct assembly is running and swinging, the motor wiring will be pulled back and forth by the torque, and it is easy to scratch the moving mechanism, causing damage or breakage of the motor wiring. For example, the torque applied to the motor wiring is too large, which affects the service life, and it is easy to be damaged by the whole machine shaking mechanism, affecting the service life.

[0028] In order to better understand the purpose, structure and function of the present invention, the tower fan motor wiring connection structure and the tower fan of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-3 As shown, the tower fan motor wiring connection structure of the present invention includes an air duct assembly, a motor assembly 2 arranged in the air duct assembly, a crossflow impeller 6 is arranged on one side of the motor assembly, and a gear 3 is arranged on the other side. A motor bracket 1 is also arranged in the motor assembly, and the motor assembly 2 is connected to the motor bracket 1 and supported by the motor bracket inside the air duct assembly. The motor assembly is preferably a DC motor assembly, such as an outer rotor DC motor assembly, and can also be other existing motor assemblies. The motor assembly has motor wiring, and the motor wiring is guided out from the inner side of the air duct assembly.

[0030] like Figure 4-5 As shown, the motor bracket is cylindrical, and the cylindrical motor bracket includes a cylindrical side wall, one side of the motor bracket side wall has an opening, and the other side has a bottom wall. The motor assembly is installed into the motor bracket through the opening of the motor bracket. For example, the motor bracket 1 is provided with a positioning column 15 and a screw column 16, and the motor assembly 2 is provided with a positioning hole 21 and a screw through hole 22. When the motor assembly 2 is assembled with the motor bracket 1, the positioning column 15 on the motor bracket 1 is embedded in the positioning hole 21 of the motor assembly 2, and a screw is inserted into the screw through hole 22 on the motor assembly 2 and the screw column 16 on the motor bracket 1, so that the motor assembly is fixedly connected to the motor bracket 1.

[0031] Furthermore, a limiting component and a wire groove 14 are provided on the motor bracket 1. The wire groove 14 and the limiting component are respectively arranged on both sides of the motor bracket 1. Specifically, the wire groove 14 is arranged on the side wall edge of the opening side of the motor bracket 1, and the limiting component is arranged on the outer side of the bottom wall of the motor bracket 1. The motor wiring of the motor assembly installed in the motor bracket 1 passes through the wire groove 14, extends along the outer surface of the side wall of the motor bracket 1 and is connected to the limiting component. The limiting component limits the motor wiring.

[0032] The limiting assembly includes at least one first limiting buckle 12, which can limit the motor wiring extending from the wire groove 14. The first limiting buckle 12 is preferably arranged in the middle of the bottom wall of the motor bracket 1. After being limited by the first limiting buckle 12, the motor wiring passes out from the middle of the air duct assembly and the gear, thereby assembling the motor wiring 24 to the operating center position of the air duct assembly. The torque at the operating center position of the air duct assembly is the smallest, thereby reducing the pulling torque on the motor wiring 24 when the tower fan is running, and fully protecting the motor wiring 24.

[0033] Preferably, if Figure 6As shown, a wire passing hole 45 is provided in the middle of the air duct assembly, and a wire passing hole 33 is provided in the middle of the gear 3. The wire passing hole 45 of the air duct assembly is aligned with the wire passing hole 33 of the gear 3. The motor wiring is limited by the first limit buckle 12 and then passes out from the middle of the air duct assembly and the gear to the outside, thereby ensuring that the motor wiring 24 extends along the central axis direction of the air duct assembly, so that the motor wiring 24 is in a position where the pulling torque is minimum or zero, so as to fully protect the motor wiring 24.

[0034] The limiting assembly preferably includes a first limiting buckle 12 and a second limiting buckle 11. The second limiting buckle 11 is arranged on the outer side of the bottom wall of the motor bracket 1 and is adjacent to the first limiting buckle 12. The first limiting buckle 12 and the second limiting buckle 11 cooperate to limit the motor wiring 24. The two fixed fulcrums can enhance the limiting effect of the motor wiring 24 to prevent the motor wiring 24 from sending displacement or movement when the tower fan is running.

[0035] Furthermore, an axial guide groove is provided on the outer side of the side wall of the motor bracket 1, and a third limiting buckle 13 is provided on the upper part of the axial guide groove. The motor wiring 24 passing through the wire groove 14 extends along the axial guide groove and is limited by the third limiting buckle 13. The axial guide groove and the third limiting buckle 13 can well define the position of the motor wiring 24. Therefore, when the motor rotates at high speed, it can avoid the rotor and the motor wiring 24 from contacting and rubbing, which affects the operation of the whole machine and other safety issues.

[0036] The air duct assembly comprises an air duct rear shell 4 and an air duct front shell 5. The air duct rear shell 4 and the air duct front shell 5 are both semi-cylindrical in shape. The air duct rear shell 4 and the air duct front shell 5 are assembled to form a cylindrical air duct assembly.

[0037] The motor bracket 1 is connected to the air duct rear shell 4, and a screw through hole 18 and a positioning hole 17 are provided on the motor bracket. A first screw column 44 and a first positioning column 43 are provided on the air duct rear shell 4. When the motor bracket 1 is assembled with the air duct rear shell 4, the first positioning column 43 of the air duct rear shell 4 is embedded in the positioning hole 17 of the motor bracket 1, and screws are used to pass through the screw through hole 18 on the motor bracket 1 and the first screw column 44 of the air duct rear shell 4 respectively, so as to fix the motor bracket 1 with the air duct rear shell 4.

[0038] like Figure 6-7 As shown, the gear 3 is connected to the air duct rear shell 4, and a second positioning column 42 and a second screw column 41 are provided on the air duct rear shell 4. A positioning hole 32 and a screw through hole 31 are formed on the gear 3. When the gear 3 is assembled with the air duct rear shell 4, the positioning column 42 on the air duct rear shell 4 is embedded in the positioning hole 32 of the gear 3, and screws are respectively inserted into the screw through hole 31 of the gear 3 and the screw column 41 of the air duct rear shell 4, so that the gear 3 is fixedly connected with the air duct rear shell 4.

[0039] Preferably, the bottom wall of the air duct assembly is fixedly connected to or integrally formed with the air duct rear shell 4 , and the wire hole 45 is arranged in the middle of the bottom wall of the air duct assembly.

[0040] Furthermore, the motor wiring 24 preferably has multiple wires, which are enclosed in a wire tube. The wire tube is made of flexible or rigid material. When the wire tube is made of rigid material, the shape of the wire tube is L-shaped to match the structure of the internal wiring channel of the tower fan.

[0041] Therefore, in the tower fan motor wiring connection structure of the present invention, the motor wiring on the motor assembly 2 passes through the wire groove 14, the axial guide groove, the limit buckle 13, the limit assembly (limit buckle 11 and limit buckle 12) of the motor bracket 1, the wire hole 45 of the air duct rear shell 4, and the wire hole 32 of the gear 3 in sequence, and is connected with the above structure, thereby completing the wiring extension and fixation of the motor wiring.

[0042] Therefore, when the tower fan is running and the rotor 23 of the motor assembly rotates at high speed, the motor wiring connection structure of the present invention can avoid contact and friction between the rotor and the motor wiring 24, thereby avoiding damage or disconnection of the motor wiring and affecting the operation of the whole machine. The limit assembly assembles the motor wiring 24 to the central axis position of the air duct assembly, so that the motor wiring is set at a position where the torque is minimum or zero, and avoids damage to the motor wiring due to torsional pulling force. At the same time, the motor wiring is passed through the wire hole 45 of the air duct rear shell 4 and the wire hole 33 of the gear 3. When the wind wheel in the air duct assembly runs at high speed or the shaking function is realized through the gear, the motor wiring 24 is protected to avoid excessive force affecting the service life of the wiring.

[0043] The present invention also discloses a tower fan, which comprises the tower fan motor wiring connection structure. The tower fan with the tower fan motor wiring connection structure has better safety performance and a long service life.

[0044] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
