Description

Technical Field

[0001] The utility model relates to the technical field of fabric machines, and more specifically, to a fabric machine with a motor heat dissipation structure. Background Art

[0002] A fabric machine is a device used for surface cleaning of textiles. Currently, the fabric machines on the market mainly include a housing, a water pump, an air pump, a steam generating device, a clean water tank, a waste water tank, a negative pressure fan, and a cleaning head. The water pump, the air pump, the steam generating device, and the negative pressure fan are all installed inside the housing. The clean water tank and the waste water tank are connected to the upper part of the housing. The steam generating device is connected to the water pump and the air pump. The water pump is connected to the clean water tank. The negative pressure fan is connected to the waste water tank. The cleaning head is connected to the clean water tank and the waste water tank through pipelines. When the fabric machine is working, the water pump can pump the water in the clean water tank to the steam generating device, the air pump can transport compressed air to the steam generating device, the steam generating device can transport the steam to the cleaning head through pipelines, and the steam ejected from the cleaning head can clean the surface of the textiles. At the same time, when the negative pressure fan is working, it can create negative pressure in the waste water tank, and the steam or liquid water after cleaning the surface of the textiles can be sucked into the waste water tank. However, in the existing fabric machine structure, when the fabric machine is working, since the existing fabric machine does not have a structure for reliably dissipating heat from the drive motor in the negative pressure fan, when the fabric machine is used for a long time, it is easy to cause the drive motor in the negative pressure fan to overheat and be damaged, that is, it will affect the service life of the drive motor in the negative pressure fan. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a fabric machine with a motor heat dissipation structure, which can avoid the drive motor in the negative pressure fan assembly from overheating and being damaged.

[0004] The utility model provides a fabric machine with a motor heat dissipation structure, including a housing assembly and a negative pressure fan assembly. The fabric machine also includes a cover shell and a duct. The cover shell covers the outside of the negative pressure fan assembly and presses the negative pressure fan assembly on the housing assembly. The outer edge of the lower end of the cover shell is fixed to the housing assembly. An air outlet hole is provided at the top of the cover shell, and the air outlet hole is vertically corresponding to the air outlet end of the drive motor in the negative pressure fan assembly. The duct is fixed on the outer side wall of the cover shell. An air inlet interface is provided on the side wall of the cover shell. The air outlet of the duct is connected to the air inlet interface. An air inlet channel is provided on the housing assembly on one side of the cover shell. An air inlet hole group communicated with the air inlet channel is provided on the side wall of the housing assembly. The air inlet of the duct is connected to the air inlet channel. An air outlet grille is also provided on the side wall of the housing assembly.

[0005] After adopting the above structure, when the drive motor in the negative pressure fan assembly works, the air in the external environment can sequentially enter the housing through the air inlet hole group, the air inlet channel and the air guide pipe. The air entering the housing can cool the drive motor, and the air cooled by the drive motor can be discharged from the air outlet end of the drive motor through the fan blades fixed on the rotor of the drive motor. The air discharged from the air outlet end of the drive motor can be discharged outside the housing assembly through the air outlet holes at the top of the housing and the air outlet grilles on the side wall of the housing assembly in sequence. Through the above process, the heat dissipation of the drive motor in the negative pressure fan assembly is realized, so that the drive motor in the negative pressure fan assembly can be prevented from being damaged due to overheating, that is, the service life of the drive motor in the negative pressure fan assembly can be prolonged.

[0006] In a possible implementation manner, an annular step is provided on the outer wall of the upper end of the drive motor, and a rubber ring is embedded on the annular step. An annular groove is provided on the inner top of the housing, and the outer edge of the rubber ring is fitted with the annular groove. After adopting this structure, under the action of the rubber ring, the housing can achieve flexible pressing of the negative pressure fan assembly. Therefore, when the negative pressure fan assembly works and generates vibration, the rubber ring can absorb the vibration generated by the negative pressure fan assembly, and further reduce the noise during the operation of the fabric machine.

[0007] In a possible implementation manner, an arc-shaped air guide plate is provided on the inner side of the housing at the position where the air inlet interface is located. The air guide plate is coaxially arranged with the inner peripheral wall of the housing. A ventilation gap is formed between the air guide plate and the inner side wall of the housing. The air guide plate extends along the circumferential direction of the housing, and the air inlet interface is located in the middle of the extending direction of the air guide plate. After adopting this structure, after the air enters the housing through the air inlet interface, the air can impact on the air guide plate and diffuse to the circumferential direction inside the housing through the ventilation gap, so that the air can better achieve circumferential cooling of the drive motor, that is, the cooling effect on the drive motor can be improved.

[0008] In a possible implementation manner, an annular slot is provided on the outer wall of the housing, and the annular slot is located on the outer side of the circumferential direction of the air inlet interface. An annular insertion plate is provided on the outer wall of the air guide pipe, and the annular insertion plate is located on the outer side of the circumferential direction of the air outlet of the air guide pipe. The annular insertion plate is matched and inserted with the annular slot. After adopting this structure, when the air guide pipe and the housing are assembled, the annular insertion plate can be matched and inserted with the annular slot, so as to realize the positioning and limiting functions of the housing and the air guide pipe, and further facilitate the assembly of the housing and the air guide pipe, and improve the reliability after the housing and the air guide pipe are assembled.

[0009] In a possible implementation, a noise reduction cotton is embedded inside the air outlet of the air duct, and the noise reduction cotton is pressed against the inner side wall of the air duct through the air inlet interface; by providing the noise reduction cotton, when the air from the air inlet hole group flows through the noise reduction cotton, the noise reduction cotton can function to reduce the wind noise, that is, it can reduce the noise when the fabric machine is working; in addition, the noise reduction cotton can also have a certain dust absorption effect to prevent dust from entering the housing.
