Description

Technical Field

[0001] This utility model relates to the field of air conditioning fan coil unit technology, and in particular to a fan coil unit with air purification function. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, indoor air quality has received increasing attention. In modern buildings, air conditioning systems not only need to meet basic temperature and humidity control requirements, but also need to improve and purify indoor air. Fan coil units, as important terminal equipment in central air conditioning systems, are widely used in various commercial and residential buildings. Their main function is to drive air circulation through fans and use internal heat exchangers to cool or heat the air. However, traditional fan coil unit equipment only has basic air handling capabilities and is insufficient to cope with increasingly complex indoor air pollution problems, such as the intrusion of pollutants like PM2.5, bacteria, viruses, and volatile organic compounds.

[0003] According to the fan coil unit with patent publication number CN222504054U, it includes a fan coil unit body, two fans located at the rear of the fan coil unit body, a coil inside the fan coil unit body, and the water inlet and outlet of the coil located on one side of the fan coil unit body. A tray is located below the fan coil unit body, and drain hoses are fixed on both sides of the tray. An exhaust channel is fixed on the rear wall inside the tray, and an air outlet slot is opened on the front side of the exhaust channel. This fan coil unit mainly improves the service life of the tray by improving the tray design and solving the problem of tray corrosion caused by condensation. However, it does not improve the air duct filter. Over time, these pollutants may accumulate and cause partial blockage of the pipes. If the air inlet or exhaust channel of the fan coil unit is partially blocked by dust, mold, or other substances, it will not only affect the air circulation efficiency and reduce the cooling or heating effect, but may also increase energy consumption. Therefore, it is necessary to improve the existing fan coil unit and design a fan coil unit with air purification function. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a fan coil unit with air purification function.

[0005] The technical solution is as follows: A fan coil unit with air purification function includes a fan coil unit body, a housing, and a dual-shaft motor. The fan coil unit body serves as the assembly carrier for this equipment. The housing is fixedly installed on the coil of the fan coil unit body, covering the outer perimeter of the coil. A dual-shaft motor is fixedly installed inside the fan coil unit body, and the bidirectional output shaft of the dual-shaft motor is connected to the impeller shaft of the turbine fan inside the fan coil unit body. It also includes primary filters disposed on both sides of the housing of the fan coil unit body. The primary filters are located at the air inlet of the turbine fan in the fan coil unit body. A purification frame is installed near the air outlet of the turbine fan inside the fan coil unit. An activated carbon plate is detachably installed inside the purification frame. The purification frame is slidably snapped into the fan coil unit body by a locking device. A worm gear is fixedly installed on the output shaft of the dual-shaft motor.

A worm wheel is fixedly installed on the rotating shaft. The worm wheel and the worm gear mesh with each other. A reduction shaft is fixedly connected to the output shaft of the reducer. A reminder is provided at the bottom of the fan coil unit body to prompt the user to replace the activated carbon plate.

[0006] Furthermore, the primary filter screen is detachably installed on the outer shell of the fan coil unit by bolts. By unscrewing the bolts on the primary filter screen, the removed primary filter screen can be cleaned or replaced.

[0007] Furthermore, the locking component includes a connecting frame, a guide rod, a wedge block, and a spring. The bottom of the fan coil unit body is provided with a number of connecting frames that are the same as the number of purification frames. A guide rod is fixedly connected to the connecting frame, and a wedge block is slidably connected to the guide rod. The wedge block is snapped onto the outer shell of the purification frame, and a spring is sleeved on the guide rod between the connecting frame and the wedge block.

[0008] Furthermore, a contact plate is fixedly connected to the wedge block, and an electric push rod with the same number as the wedge block is fixedly installed at the bottom of the fan coil unit body. The piston rod of the electric push rod is in contact with the contact plate.

[0009] Furthermore, the indicator includes an indicator rod and a reference scale. The indicator rod is fixedly connected to the reduction shaft. A reference scale is provided at the bottom of the fan coil unit. The reduction shaft is located at the center of the circular reference scale. The gear reducer drives the turbine fan through a worm gear and a worm recording wheel dual-axis motor. The gear reducer slowly drives the indicator rod to rotate through the reduction shaft. By observing the position of the indicator rod on the reference scale, the user can determine the working time of the dual-axis motor driving the turbine fan.

[0010] Furthermore, a transparent cover is provided at the bottom of the fan coil unit body at the reference scale. The transparent cover covers the indicator rod and the reference scale, and the transparent cover is used to protect the indicator rod from damage during normal operation.

[0011] Compared with the prior art, the present invention has the following advantages:

Detailed Implementation

[0022] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0023] A fan coil unit with air purification function, such as Figures 1-6 As shown, the device includes a fan coil unit body 1, a housing 2, and a dual-shaft motor 4. The fan coil unit body 1 serves as the assembly carrier for this equipment. The housing 2 is fixedly installed on the coil of the fan coil unit body 1, covering the outer perimeter of the coil. The dual-shaft motor 4 is fixedly installed inside the fan coil unit body 1, and its bidirectional output shaft is connected to the impeller shaft 8 of the turbine fan 401 inside the fan coil unit body 1. The device also includes primary filters 3 located on both sides of the housing 2 of the fan coil unit body 1. The primary filters 3 are located at the air inlet of the turbine fan 401 in the fan coil unit body 1. A purification frame 5 is installed inside the fan coil unit body 1 near the air outlet of the turbine fan 401. An activated carbon plate 51 is detachably installed inside the purification frame 5, and the purification frame 5 is slidably secured inside the fan coil unit body 1 by a locking mechanism. A worm gear 6 is fixedly installed on the output shaft of the dual-shaft motor 4, and a gear reducer 9 is fixedly installed inside the fan coil unit body 1. A rotating shaft 8 is fixedly connected to the input shaft of the gear reducer 9, and a worm gear 7 is fixedly installed on the rotating shaft 8. The worm gear 7 and the worm 6 mesh with each other. A reduction shaft 10 is fixedly connected to the output shaft of the reducer. A reminder is provided at the bottom of the fan coil unit 1 to prompt the user to replace the activated carbon plate 51. When the dual-axis motor 4 synchronously drives the turbine fan 401 to blow air into the fan coil unit 1, the airflow will be filtered by the primary filter 3 and the activated carbon plate 51 in sequence. At the same time, the worm 6 meshes with the worm gear 7, and the gear reducer 9 can reduce the speed and record the rotation status of the dual-axis motor 4 driving the turbine fan 401. When the dual-axis motor 4 drives the turbine fan 401 for a preset time, the user can know the current usage time of the primary filter 3 and the activated carbon plate 51 through the reminder on the outside of the fan coil unit 1, so as to replace and maintain them in time, and keep the fan coil unit 1 with good air purification effect.

[0024] like Figure 2 As shown, the primary filter 3 is detachably installed on the outer shell 2 of the fan coil unit body 1 by bolts. By unscrewing the bolts on the primary filter 3, the primary filter 3 can be cleaned or replaced.

[0025] like Figure 1 and Figure 5 As shown, the locking mechanism includes a connecting frame 13, a guide rod 131, a wedge block 14, and a spring 15. The bottom of the fan coil unit body 1 is provided with a number of connecting frames 13 that are the same as the number of purification frames 5. The guide rod 131 is fixedly connected to the connecting frame 13, and the wedge block 14 is slidably connected to the guide rod 131. The wedge block 14 is snapped onto the outer shell 2 of the purification frame 5. A spring 15 is sleeved on the guide rod 131 between the connecting frame 13 and the wedge block 14. Under the action of the spring 15, the wedge block 14 can be locked and slidably installed onto the purification frame 5 of the fan coil unit body 1.

[0026] like Figure 5 As shown, a contact plate 151 is fixedly connected to the wedge block 14. The bottom of the fan coil unit body 1 is fixedly installed with an electric push rod 16 of the same number as the wedge block 14. The piston rod of the electric push rod 16 is in contact with the contact plate 151. When the piston rod of the electric push rod 16 extends, it will overcome the elastic force of the spring 15 and press the contact plate 151, causing the wedge block 14 to disengage from the lock on the purification frame 5, thereby facilitating the user to replace the activated carbon plate 51 inside the purification frame 5.

[0027] like Figure 4 and Figure 5 As shown, the indicator includes an indicator rod 101 and a reference scale 11. The indicator rod 101 is fixedly connected to the reduction shaft 10. A reference scale 11 is set at the bottom of the fan coil unit body 1. The reduction shaft 10 is located at the center of the circular reference scale 11. The gear reduction box 9 drives the turbine fan 401 through the worm gear 6 and the worm recording wheel dual-axis motor 4. The gear reduction box 9 slowly drives the indicator rod 101 to rotate through the reduction shaft 10. By observing the position of the indicator rod 101 on the reference scale 11, the user can determine the working time of the dual-axis motor 4 driving the turbine fan 401, and thus determine whether the primary filter 3 and the activated carbon plate 51 need maintenance.

[0028] like Figure 4 As shown, a transparent cover 12 is provided at the bottom of the fan coil unit body 1 at the reference scale 11. The transparent cover 12 covers the outer periphery of the indicator rod 101 and the reference scale 11. The transparent cover 12 is used to protect the indicator rod 101 from working normally, and at the same time, it can not affect the user's observation of the indicator rod 101 and the reference scale 11.

[0029] After the fan coil unit starts, the dual-shaft motor 4 synchronously drives the turbine fan 401 to rotate at high speed through the bidirectional output shaft. The suction force generated by the fan draws air in from the air inlets on both sides of the equipment casing 2. Before entering the turbine fan 401, the air first passes through the primary filter 3 installed at the air inlet, filtering out larger particles such as hair and dust, completing the first stage of filtration. Then, the drawn-in air is pressurized by the turbine fan 401 and blown out from the air outlet. When flowing through the air outlet area, the air is forced through the purification frame 5 set inside the fan coil unit body 1. The activated carbon plate 51, which can be detachably installed inside the purification frame 5, performs a second stage of deep purification of the air, effectively adsorbing odors, harmful gases and finer pollutants, and finally outputting clean air. At the same time, the worm gear 6 fixed on the output shaft of the dual-shaft motor 4 also rotates and meshes with the worm wheel 7 fixed on the rotating shaft 8. The rotating shaft 8 inputs power into the gear reducer 9, which greatly reduces the speed, and then outputs slowly through the reduction shaft 10. As the fan coil unit rotates, the indicator rod 101 fixed on the reduction shaft 10 moves extremely slowly on the circular reference scale 11 set at the bottom of the fan coil unit body 1. When the cumulative running time of the equipment reaches the preset value, the user can determine that maintenance is needed by observing the position of the indicator rod 101. At this time, the bolts can be unscrewed to remove the primary filter 3 for cleaning or replacement. When replacing the activated carbon plate 51, the electric push rod 16 at the bottom of the fan coil unit body 1 is activated. The piston rod of the electric push rod 16 extends and presses the contact plate 151 fixed on the wedge block 14, so that the wedge block 14 overcomes the elastic force of the spring 15 and slides along the guide rod 131, thereby releasing the lock on the purification frame 5. The user can then pull out the purification frame 5 to replace the internal activated carbon plate 51. After completion, the purification frame 5 is pushed back, the electric push rod 16 retracts, and the spring 15 pushes the wedge block 14 to reset and relock. Thus, through the combination of secondary filtration and mechanical timing structure, the equipment can continuously and efficiently purify the air and remind the user to maintain the filter material in time.
