Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal concealed fan technology, specifically a high-efficiency heat exchange horizontal concealed fan coil unit. Background Technology
[0002] Horizontal concealed fan coil units are a common type of air conditioning terminal equipment, typically installed in concealed spaces such as ceilings in buildings. They are horizontally rectangular and mainly consist of a fan, coil, motor, air filter, and condensate pan. During operation, the fan draws in indoor air, which exchanges heat with the cooling or heating coil, lowering or raising the air temperature before being returned to the room. This achieves the purpose of indoor temperature regulation. They are characterized by saving indoor space, quiet operation, high aesthetic appeal, and good temperature control, and are widely used in air conditioning systems of various buildings such as office buildings, hotels, hospitals, and residences.
[0003] In current horizontal concealed fan coil unit technology, traditional filter cleaning methods present many inconveniences. Since the fan coil unit is installed in a concealed location, cleaning the filter often requires a significant amount of manpower and time to completely disassemble the fan coil unit. This cumbersome and complex process not only increases maintenance costs but may also damage the equipment due to frequent disassembly, affecting its normal service life. Moreover, if cleaning is not timely, the dust-filled filter will severely obstruct airflow, reduce the heat exchange efficiency of the fan coil unit, and consequently affect the equipment's heat dissipation performance, leading to a decrease in indoor temperature regulation capabilities and an inability to meet users' needs for a comfortable environment. Therefore, it is necessary to design a horizontal concealed fan coil unit with high-efficiency heat exchange. Utility Model Content

[0027] This utility model provides the following technical solution:
[0028] Example 1
[0029] Combination Figures 2 to 7 A high-efficiency heat exchange horizontal concealed fan coil unit includes a concealed fan device 1, a heat exchange mechanism 2 fixedly connected to the surface of the concealed fan device 1, and a locking mechanism 3 fixedly connected to one end of the top of the heat exchange mechanism 2.
[0030] The heat exchange mechanism 2 includes a vertical frame 21, which is fixedly connected to the front of the concealed fan device 1. A filter screen 22 is installed inside the vertical frame 21. A top strip 23 is fixedly connected to the top of the filter screen 22. Support blocks 24 are fixedly connected to the upper and lower ends of both sides of the vertical frame 21. A vertical rod 26 is fixedly connected inside the support block 24. A first spring 241 is fixedly connected to the bottom of the top support block 24. A bottom strip 25 is fixedly connected to the bottom of the first spring 241. A fan plate 27 is fixedly connected to the inside of the concealed fan device 1 near the surface of the filter screen 22. An exhaust fan 28 is fixedly connected inside the fan plate 27. A heat dissipation coil 29 is fixedly connected inside the concealed fan device 1. A slot is opened inside the vertical frame 21, and the surface of the filter screen 22 is inserted into the slot.
[0031] Furthermore, vertical holes are opened at both ends of the bottom strip 25, and the surface of the vertical rod 26 is slidably connected to the vertical holes. Under the elastic action of the first spring 241, the top strip 23 drives the bottom strip 25 to move upward inside the vertical frame 21, thereby driving the filter screen 22 upward inside the vertical frame 21, and then accordingly pulling the filter screen 22 out of the vertical frame 21. This makes it easy to clean the dust on the surface of the filter screen 22, thereby ensuring the heat dissipation of the concealed fan equipment 1.
[0032] Example 2
[0033] See Figure 1-7Furthermore, based on Embodiment 1, the locking mechanism 3 further includes a locking seat 31, which is fixedly connected to the top of the surface of the vertical frame 21. A second spring 35 is fixedly connected to both ends of the inside of the locking seat 31. A slider 33 is fixedly connected to one end of the second spring 35. A handle 34 is fixedly connected to the top of the slider 33. A horizontal bar 32 is fixedly connected to the surface of the slider 33. A vertical bar 36 is fixedly connected to one end of the horizontal bar 32. Locking frames 38 are fixedly connected to both sides of the surface of the top bar 23. Locking blocks 37 are fixedly connected inside the locking frames 38. A guide groove is opened inside the locking seat 31. The surface of the slider 33 is slidably connected to the inside of the guide groove. A locking slot is opened at the top of the vertical bar 36. The surface of the locking block 37 matches the inside of the locking slot.
[0034] Furthermore, through holes are opened at both ends of the card holder 31, and the surface of the crossbar 32 passes through the through holes at both ends of the card holder 31. When the filter screen 22 is too dusty and needs to be cleaned, the handle 34 is pulled to drive the slider 33 to slide inside the card holder 31, thereby causing the crossbar 32 to move and drive the vertical bar 36 to disengage from the card block 37, thereby releasing the limit of the card frame 38 and realizing the installation limit control function of the filter screen 22.
[0035] In actual operation, when this device is in use, for efficient heat dissipation of the concealed fan equipment 1, the heat inside the concealed fan equipment 1 is dissipated through the heat dissipation coil 29. When heat dissipation needs to be strengthened, the exhaust fan 28 draws air to quickly extract the heat through the filter screen 22 to the outside of the concealed fan equipment 1. When the filter screen 22 is too dusty and needs to be cleaned, the handle 34 is pulled to drive the slider 33 to slide inside the bracket 31, thereby driving the horizontal bar 32 to move and causing the vertical bar 36 to disengage from the locking block 37. This releases the limit of the bracket 38, allowing the top bar 23 to move the bottom bar 25 upward inside the vertical frame 21 under the elastic action of the first spring 241. This causes the filter screen 22 to move upward inside the vertical frame 21, and then the filter screen 22 is pulled out of the vertical frame 21. This makes it easy to clean the dust on the surface of the filter screen 22, thus ensuring the heat dissipation of the concealed fan equipment 1.
