Technical Field
[0001] This utility model relates to a bladeless tower fan, and more particularly to a bladeless tower fan, belonging to the technical field of bladeless tower fans. Background Technology
[0002] Tower fans, also known as convection fans, are based on the principles of aerodynamics. They create a three-dimensional air exchange system between indoor and outdoor air, similar to a blower used in a stove. Even without fan blades, they can still deliver airflow. When used in conjunction with an air conditioner, they create airflow circulation, making them suitable for families with elderly people and children.
[0003] The bladeless tower fan with heating and cooling functions disclosed in application number "202121904059.5" "includes a lower shell and an upper shell disposed on the lower shell. The lower shell has a vortex cavity inside, and a rotatable turbine is disposed inside the vortex cavity. The upper shell has an air duct connected to the vortex cavity. An air outlet is opened on the upper shell, and a heating device is disposed at the air outlet. The heating device adopts a combination of PTC heating element and graphene material as the air outlet, and the power distribution between the two can be adjusted." This utility model has a simple structure, is easy to operate, and meets the needs of both winter and summer use scenarios.
[0004] However, the above method still has the following drawbacks: it uses a turbine to deliver air to the duct, and the air carries the heat from the heating device through the air outlet to deliver hot air, which can be turned off when not in use; however, in actual use, since the hot and cold air delivered by the duct is directed to a certain point, the air delivery area is limited, which affects the uniform distribution of indoor temperature and comfort; especially in certain situations, this fixed-point air delivery method often causes some areas to be too hot or too cold, reducing the user experience. Utility Model Content
[0005] The purpose of this invention is to provide a bladeless tower fan to solve the problem mentioned in the background art, which is that the air delivery area is limited due to the fixed-point air delivery of the air duct, thus affecting the uniform distribution of indoor temperature and comfort.

[0025] Please see Figure 1-6 This utility model provides a bladeless tower fan, including a base 1, a circular plate 2 rotatably mounted on the top of the base 1, a bottom shell 3 fixedly mounted on the top of the circular plate 2, a tower body 4 fixedly mounted on the top of the bottom shell 3, a turbine shell 5 fixedly mounted inside the bottom shell 3, the turbine shell 5 being an existing device, which can be driven by an internal motor to rotate the turbine and transport air through a duct 6; a duct 6 is opened on one side of the tower body 4 to facilitate air transport and user convenience; the air outlet of the turbine shell 5 is fixedly connected to the bottom end of the duct 6, and an annular sealing gasket is provided between them to seal the connection; a rotating rod 7 is fixedly mounted at the center of the bottom end of the circular plate 2, the bottom end of the rotating rod 7 is rotatably connected to the bottom end of the inner wall of the base 1, a gear 8 is fixedly mounted at the bottom of the rotating rod 7, and a rack plate 9 is meshed with one side of the gear 8. A support arm 10 is rotatably mounted on one side of the rack plate 9. By swinging the support arm 10, the rack plate 9 can be moved horizontally, thereby driving the gear 8 to rotate in both directions. This, in turn, drives the rotating rod 7 and the circular plate 2 to rotate, causing the bottom shell 3 and the tower body 4 on top of the circular plate 2 to rotate synchronously and repeatedly. This increases the air supply area, ensures uniform indoor temperature distribution, and improves indoor comfort. Especially in specific situations, it prevents some areas from becoming too hot or too cold, improving the user experience. The bottom of the inner wall of the base 1 is provided with a moving component 11 for moving the support arm 10, which facilitates repeated movement of the rack plate 9 connected to the support arm 10. The bottom of the circular plate 2 is provided with a guide component 12, which makes the circular plate 2 more stable during rotation.
[0026] The moving component 11 includes a support block 1101, which is fixedly installed on the bottom end of the inner wall of one side of the base 1. A motor 1102 is fixedly installed at the top of the support block 1101. A rotating plate 1103 is fixedly installed on the output shaft of the motor 1102. The rotating plate 1103 is rotatably connected to the support arm 10. A guide block 13 is fixedly installed in the middle of the rack plate 9. A guide strip 14 is slidably installed in the middle of the guide block 13. Both ends of the guide strip 14 are fixedly connected to the inner wall of the base 1. Through the moving component 11, the rotating plate 1103 is driven to rotate by the motor 1102. Combined with the rotating support arm 10, the rack plate 9 moves repeatedly in the horizontal direction under the action of the guide block 13 and the guide strip 14, thereby driving the meshing gear 8 to rotate repeatedly, which can drive the rotating rod 7 to perform forward and reverse rotation operations.
[0027] The guide assembly 12 includes several support rods 1201, which are installed at equal intervals along the circumference at the bottom of the circular plate 2. A bullseye wheel 1202 is fixedly provided at the bottom of the support rods 1201. A ring 1203 is fixedly provided at the top of the inner wall of the base 1. A moving groove 1204 is provided at the top of the ring 1203 to move and cooperate with the bullseye wheel 1202. By using the guide assembly 12, the rotation of the circular plate 2 can drive the multiple support rods 1201 and the bullseye wheel 1202 at equal intervals along the circumference to rotate. Combined with the moving groove 1204 at the ring 1203, the circular plate 2 can be made more stable during rotation, thereby improving the stability of the tower body 4 during rotation.
[0028] An air inlet plate 17 is embedded on one side of the bottom shell 3, and a dustproof net 20 is fixedly installed on one side of the air inlet plate 17. The air inlet plate 17 and the dustproof net 20 facilitate the entry of air into the air body through the air inlet plate 17 and also serve as a dustproof function. A rotary switch 21 is fixedly installed at the bottom of the bottom shell 3 for easy control of various electrical devices. Mounting blocks 18 are fixedly installed at the middle of the bottom end and the middle of the top end of the air inlet plate 17. The surface of the bottom shell 3 has mounting grooves that engage with the mounting blocks 18. Bolts 19 are threadedly connected to the middle of the mounting blocks 18. Threaded holes for threaded connection with the bolts 19 are opened on the surface of the bottom shell 3. The mounting blocks 18 and the bolts 19 allow the air inlet plate 17 to be disassembled and installed, facilitating timely disassembly and maintenance of the dustproof net 20.
[0029] A heating wire 15 is fixedly installed at the air outlet of the turbine housing 5. The heating wire 15 facilitates the output of hot water from the bladeless tower fan, meeting the needs of both winter and summer use. An air outlet plate 16 is fixedly installed on one side of the air duct 6, which facilitates ventilation.
[0030] A mechanical seal is fixed at the connection between the base 1 and the circular plate 2, which can play a sealing role. A support plate 22 is fixed at the bottom of the base 1, and an anti-slip pad is fixed at the bottom of the support plate 22. The support plate 22 and the anti-slip pad at the bottom of the base 1 can provide support and anti-slip for the bladeless tower fan.
[0031] In use, the bladeless tower fan is first placed in a suitable working location. The turbine inside the turbine housing 5 is rotated, and in conjunction with the air inlet plate 17, air is delivered into the air duct 6 for blowing. When hot air is needed, the heating wire 15 is activated to deliver hot air. When the air delivery area needs adjustment, the rotating plate 1103 is driven to rotate by the motor 1102. Combined with the rotating support arm 10, and under the action of the guide block 13 and guide strip 14, the rack plate 9 moves repeatedly in the horizontal direction, thereby driving the meshing gear 8 to rotate repeatedly, thus driving the fan to rotate. The rod 7 rotates in both directions, thereby driving the circular plate 2, the bottom shell 3, and the tower body 4 to rotate and adjust synchronously. This increases the air supply area, ensuring a uniform distribution of indoor temperature and improving indoor comfort. Furthermore, in specific situations, the system can effectively prevent overheating or undercooling in certain areas, improving user experience. During this process, the circular plate 2, in conjunction with its bottom support rod 1201 and bullseye wheel 1202, and the moving groove 1204 at the ring 1203, ensures the stability of the circular plate 2 during rotation, significantly enhancing the stability of the tower body 4 during rotation adjustment.
