Description

Technical fields:

[0001] This utility model relates to the field of ventilation and cooling equipment technology, and more specifically to a motor protection structure for a water-cooled air conditioner. Background technology:

[0002] Evaporative air conditioners, also known as evaporative air coolers, are evaporative cooling and ventilation units that integrate cooling, ventilation, dust prevention, and deodorization. Existing evaporative air conditioners, such as the new type described in Chinese patent application number 201120147501.4, have a water tank base at the bottom of the casing. An upward-extending air guide sleeve is formed in the middle of the water tank base. A motor is fixed to the top of the sleeve via a connecting support frame. An impeller is fixed to the motor shaft and inserted into the air guide sleeve. During operation, the motor drives the impeller to rotate, causing outside air to pass through a water curtain on the side panel of the casing, evaporating the water and cooling the air before it is discharged from the bottom of the air guide sleeve. This design places the entire motor in a humid environment, making the motor casing susceptible to corrosion.

[0003] Therefore, the motors currently used are all high-temperature and moisture-resistant. However, after long-term use, they are still prone to scale buildup and surface corrosion, which can easily cause the motor to fail and require replacement, resulting in high replacement costs. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a motor protection structure for a water-cooled air conditioner. It connects the main motor in a protective support sleeve and fixes it to the ring mounting sleeve by a support leg, so that the side wall surface of the main motor is not easily in contact with air containing water vapor, reducing corrosion. Moreover, it achieves heat dissipation through the protective support sleeve, ensuring the heat dissipation effect.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A motor protection structure for a water-cooled air conditioner includes a water tank base and an upper top cover plate of the water-cooled air conditioner housing. A downwardly extending groove is formed in the middle of the top surface of the water tank base, and an upwardly extending annular mounting sleeve is formed in the middle of the bottom surface of the groove. The bottom of the annular mounting sleeve communicates with a through hole formed in the middle bottom surface of the groove. A main motor is provided above the annular mounting sleeve. Multiple connecting blocks are formed on the outer side wall of the main motor. A protective support sleeve is fitted on the outer side of the main motor. The protective support sleeve is fixed to the corresponding connecting block of the main motor by fixing bolts.

[0007] Multiple support legs are welded and fixed to the outer wall of the protective support sleeve, and the ends of the support legs are fixedly connected to the top surface of the ring mounting sleeve by bolts.

[0008] Furthermore, the top of the ring mounting sleeve is formed with an outwardly radially extending edge, and a horizontal connecting plate is fixed to the bottom surface of the end of the support leg. The horizontal connecting plate is fixedly connected to the top surface of the extending edge by bolts.

[0009] Furthermore, a reinforcing protrusion is formed on the lower outer wall of the protective support sleeve, and multiple radially extending connecting through holes are formed on the reinforcing protrusion. The connecting through holes correspond to the threaded holes formed on the corresponding connecting blocks, and the screw part of the fixing bolt is inserted into the corresponding connecting through hole and screwed into the corresponding threaded hole.

[0010] Furthermore, the inner wall of the protective support sleeve is formed with multiple raised strips, which are inserted into corresponding vertical grooves formed on the outer wall of the main motor.

[0011] Furthermore, the top surface of the protective support sleeve is higher than the top surface of the main motor.

[0012] Furthermore, the outer wall of the protective support sleeve is formed with multiple vertical heat dissipation protrusions.

[0013] Furthermore, the support leg includes two parallel elongated support plates, with multiple intermediate support blocks between the two elongated support plates. The two ends of the intermediate support blocks are welded and fixed to the inner sidewalls of the corresponding two elongated support plates.

[0014] One end of each of the two elongated support plates is welded and fixed to the outer wall of the same reinforcing protrusion, and the other end of each of the two elongated support plates is welded and fixed to the top surface of the same horizontal connecting plate.

[0015] The outstanding effect of this utility model is:

[0016] It connects the main motor within a protective support sleeve and fixes it to the circular mounting sleeve via support legs. This prevents the sidewall surface of the main motor from coming into contact with air containing water vapor, reducing corrosion. Furthermore, it achieves heat dissipation through the protective support sleeve, ensuring effective heat dissipation.

[0017] Meanwhile, the raised strip formed on the inner wall of its protective support sleeve is inserted into the corresponding vertical groove formed on the outer wall of the main motor, thereby increasing its contact area with the outer wall of the main motor and improving the heat conduction and heat dissipation effect.

[0020] For example, see below. Figures 1 to 2 As shown, a motor protection structure for a water-cooled air conditioner includes a water tank base 10 and an upper top cover plate 20 of the water-cooled air conditioner housing. The top surface of the water tank base 10 has a downwardly extending groove 11 formed in the middle. The bottom surface of the groove 11 has an upwardly extending annular mounting sleeve 12 formed in the middle. The top of the annular mounting sleeve 12 has an outwardly radially extending extension edge 121 formed. The bottom of the annular mounting sleeve 12 communicates with a through hole formed in the middle bottom surface of the groove 11. A main motor 30 is provided above the annular mounting sleeve 12. Multiple connecting blocks 31 are formed on the outer side wall of the housing of the main motor 30, and multiple screw holes are formed on the connecting blocks 31.

[0021] A protective support sleeve 40 is fitted on the outer side of the main motor 30. Multiple reinforcing protrusions 41 are formed on the lower outer side wall of the protective support sleeve 40. Each reinforcing protrusion 41 corresponds to a connecting block 31. Multiple radially extending connecting through holes 42 are formed on the reinforcing protrusions 41. The connecting through holes 42 correspond to the threaded holes formed on the corresponding connecting blocks 31. The screw part of the fixing bolt 1 is inserted into the corresponding connecting through hole 42 and screwed into the corresponding threaded hole. A washer is inserted into the screw part of the fixing bolt 1. The washer is clamped between the rotating part of the fixing bolt 1 and the outer wall surface of the reinforcing protrusion 41. A vertical slot is formed on the inner side wall of the protective support sleeve 40 corresponding to the reinforcing protrusion 41. The outer side of the connecting block 31 is inserted into the corresponding vertical slot and cooperates with the vertical slot. The outer wall surface of the connecting block 31 is in close contact with the inner wall surface of the corresponding vertical slot to achieve fixation.

[0022] The outer wall of the reinforcing protrusion 41 is provided with a support leg 50. The support leg 50 includes two parallel elongated support plates 51. Multiple intermediate support blocks 52 are provided between the two elongated support plates 51. The two ends of the intermediate support blocks 52 are welded and fixed to the inner sidewalls of the corresponding two elongated support plates 51. One end of the two elongated support plates 51 is welded and fixed to the outer wall of the same reinforcing protrusion 41, and the other end of the two elongated support plates 51 is welded and fixed to the top surface of the same horizontal connecting plate 510. The horizontal connecting plate 510 is fixedly connected to the top surface of the extension edge 121 by bolts.

[0023] Furthermore, the inner wall of the protective support sleeve 40 is formed with a plurality of protruding strips 43, which are inserted into the corresponding vertical grooves formed on the outer wall of the main motor 30. The sidewalls of the protruding strips 43 are in close contact with the inner wall of the corresponding vertical grooves to achieve heat conduction.

[0024] Furthermore, the top surface of the protective support sleeve 40 is higher than the top surface of the main motor 30, and its top end is close to the middle bottom surface of the upper top cover plate 20.

[0025] Furthermore, the outer wall of the protective support sleeve 40 is formed with multiple vertical heat dissipation protrusions 44.

[0026] Some bolts and other components in the accompanying drawings of this embodiment are not shown. In use, this embodiment operates via the main motor 30, which rotates the impeller fixed on the output shaft at the bottom of the main motor 30 (the impeller is located within the annular mounting sleeve 12). This allows external air to enter the water-cooled air conditioning unit from the water curtain on the side panel. The air exchanges heat with the water on the water curtain, causing the water to evaporate and the air temperature to decrease. Then, the air is blown out from the bottom of the annular mounting sleeve 12. When the external air enters the unit, it is protected by the protective support sleeve 40 to prevent… Air comes into contact with the outer wall of the main motor 30, reducing corrosion of the outer wall. At the same time, the protruding strip 43 of the protective support sleeve 40 is inserted into the corresponding vertical groove formed on the outer wall of the main motor 30. The side wall of the protruding strip 43 is in close contact with the inner side wall of the corresponding vertical groove, achieving heat conduction. This allows the heat inside the main motor 30 to be conducted to the protective support sleeve 40. The outer wall of the protective support sleeve 40 has multiple vertical heat dissipation protrusions 44, thereby increasing its contact area with air and improving the heat exchange and cooling effect.
