Technical Field

[0001] The utility model relates to the field of the internal fan structure of an air conditioner, in particular to a sunken fan installation structure. Background Technique

[0002] With the increasing global energy shortage and environmental protection awareness, energy conservation has become the focus of attention in all walks of life. In the industrial field, the energy consumption of industrial air conditioning systems has always been an important issue. To solve this problem, energy-saving industrial air conditioners have emerged as the times require. In traditional industrial air conditioning systems, large refrigeration units are usually used, with high energy consumption and great environmental pressure. While energy-saving industrial air conditioners adopt advanced refrigeration technologies and intelligent control means, which can effectively reduce energy consumption and reduce the negative impact on the environment.

[0003] For existing energy-saving industrial air conditioners, after the unit is debugged and installed in place, static electricity floors are laid in the machine room, and the air ducts are located under the static electricity floors. Therefore, the fans in the unit need to sink into the static electricity floor cavity. The normal height of the static electricity floor will be controlled within 600 mm. If the fan sinking operation is carried out, due to the limited installation space at the bottom of the cabinet, it will cause difficulties in the installation and later maintenance of the fan.

Specific implementation manners

[0026] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Therefore, the detailed description of the embodiments of the present invention provided in the following drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Please refer to the attached Figure 1 - attached Figure 8 , the present invention provides a sunken fan installation structure, including a cabinet 1, and the fan 2 is installed on the bottom plate 3 at the bottom of the cabinet 1 through a drawing guide mechanism. The drawing guide mechanism includes side plates 4, guide parts 5, a fan mounting plate 6 and sliders 7. The center of the bottom plate 3 has a square cavity 31. The side plates 4 are vertically installed on the left and right side walls of the square cavity 31. The longitudinal section of the guide part 5 is in a "J" shape and is located outside the two side plates 4, including a fixing plate 51, a first plane 52 and a second plane 53 that are vertically downwardly provided on both sides of the fixing plate 51. A guide rail is formed between the first plane 52 and the side plate 4. A fixing surface 54 is vertically provided at the end of the second plane 53, and a plurality of mounting holes are provided on the fixing surface 54. The fan 2 is fixed on the fan mounting plate 6, and the sliders 7 are fixed on both sides of the bottom of the fan mounting plate 6 and are located in the guide rail.

[0028] As shown in the attached Figure 3 , 4As shown in the figure, the longitudinal section of the side plate 4 is in a "Z" shape, including a connecting surface 41. On one side of the connecting surface 41, a first mounting surface 42 is vertically downward, and the first mounting surface 42 fits against the side wall of the square cavity 31. On the other side of the connecting surface 41, a second mounting surface 43 is vertically upward, and a guide rail is formed between the first plane 52 and the second mounting surface 43. Preferably, a plurality of mounting holes are provided on the first mounting surface 42, and it can be fixedly connected to the side wall of the square cavity 31 by bolts or welding. The connecting surface 41 fits against the upper surface of the bottom plate 4 and is fixedly connected to the bottom plate 3 by welding.

[0029] As shown in the Figure 7 figure, the fan mounting plate 6 is a rectangular structure with an open bottom. A circular cavity 62 adapted to the air outlet of the fan 2 is provided on its top surface 6. A plurality of mounting holes are provided on both sides of the circular cavity 62. The slider 7 is correspondingly provided with a plurality of screw holes and is connected to the fan mounting plate 6 by screws.

[0030] Furthermore, the height of the slider 7 is greater than the depth of the guide rail. Due to the self-gravity of the fan 2, when the fan 2 moves back and forth, the fan mounting plate 6 will press the second mounting surface 43, causing the second mounting surface 43 to tilt to one side, affecting the track structure. Therefore, increasing the height of the slider 7 can prevent the second mounting surface 43 from being deformed by force. The width of the slider 7 is the same as the width of the guide rail to ensure that the slider 7 can move within the guide rail.

[0031] Furthermore, a limiting plate 55 is vertically provided at the end of the guiding member 5, and the limiting plate 55 is located at the end of the guide rail. The limiting plate 55 serves to limit the continuous movement of the fan 2 and ensure that the fan 2 is located above the circular cavity 62.

[0032] Furthermore, both the side plate 4 and the guiding member 5 are formed by bending sheet metal parts, which are preset on the upper surface of the bottom plate 3, with low production costs and simple installation methods.

[0033] Optionally, an annular structure handle is installed on the front side of the fan mounting plate 6 for convenient pulling. Limiting holes are provided on the second mounting surface 43 and the side surface of the slider 7 close to the second mounting surface 43. After the fan 2 is in place, it can be fixed by a bolt to prevent displacement due to vibration during the operation of the fan.

[0034] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
