[0034] Please see Figure 1 , Figure 2 and Figure 3 This application provides a clothing processing device 100, including a clothing processing tank (not shown), a motor 30, a cooling fan 50, and a refrigerant circulation system; the clothing processing tank is used to process clothing; the motor 30 can drive the clothing processing tank to rotate; the motor 30 drives the cooling fan 50 to rotate while driving the clothing processing tank to rotate; the refrigerant circulation system includes a compressor 60, and the cooling fan 50 is used to dissipate heat from the compressor 60.
[0035] For example, the clothing processing device 100 can be a dryer, a washer-dryer combo, or a washing machine, etc.
[0036] It is understood that when the clothing processing device 100 is a dryer, the clothing processing tub is a drying tub.
[0037] The garment processing equipment 100 provided in this application embodiment can reduce the operating temperature of the compressor 60 by setting a cooling fan 50 to dissipate heat from the compressor 60, thereby reducing the failure rate of the compressor 60 and extending the service life of the compressor 60. Since the cooling fan 50 and the garment processing drum are driven by the same motor 30, there is no need to add a new motor 30 to drive the cooling fan 50 to rotate, thereby saving the production cost of the garment processing equipment 100.
[0038] Please see Figure 4 The motor 30 includes a motor shaft 31, and the cooling fan 50 is connected to the motor shaft 31.
[0039] In some embodiments, the motor 30 further includes a drive wheel 41, which is connected to the motor shaft 31 via a first drive belt 42. The drive wheel 41 is capable of driving the garment processing drum to rotate. That is, in this embodiment, the motor shaft 31 transmits power to the drive wheel 41, which then transmits power to the garment processing drum to drive it to rotate. Exemplarily, the drive wheel 41 can transmit power to the garment processing drum via a drive belt.
[0040] In other embodiments, the garment processing tub includes a tub body and a second rotating shaft connected to the tub body. The second rotating shaft is parallel to the motor shaft 31 and is connected to the motor shaft 31 via a second transmission belt. That is, in this embodiment, the motor shaft 31 directly transmits power to the garment processing tub via the second transmission belt to drive the garment processing tub to rotate.
[0041] Please see Figure 4 The motor 30 further includes a housing 32, a connecting part 33, and a first rotating shaft 34. At least a portion of the motor shaft 31 is located inside the housing 32, and the first rotating shaft 34 is disposed on the outside of the housing 32. The housing 32 and the first rotating shaft 34 are connected through the connecting part 33. The first rotating shaft 34 is parallel to the motor shaft 31, and the first transmission belt 42 is sleeved on the motor shaft 31 and the first rotating shaft 34.
[0042] Please see Figure 4 The transmission wheel 41 is connected to the first rotating shaft 34 via a bearing.
[0043] Please see Figure 1 , Figure 2 and Figure 3The garment processing device 100 further includes a circulating air duct and an impeller assembly 70. The air inlet and outlet of the circulating air duct are both connected to the garment processing drum. The impeller assembly 70 is disposed in the circulating air duct to promote the circulation of gas in the circulating air duct. The impeller assembly 70 is connected to the end of the motor shaft 31 that is away from the cooling fan 50.
[0044] It is understandable that by installing the impeller assembly 70 in the circulating air duct, the rotation of the impeller assembly 70 can be used to accelerate the air circulation in the circulating air duct, thereby speeding up the moisture loss of clothes in the drying drum (clothes processing drum) and thus increasing the drying speed.
[0045] For example, an evaporator and a condenser are arranged sequentially in the circulating air duct from the air inlet to the air outlet, and the impeller assembly 70 is arranged in the section of the circulating air duct corresponding to the section between the condenser and the air outlet.
[0046] Understandably, when the dryer (clothes handling equipment 100) is working, the circulating air in the circulating duct is heated to dry, high-temperature air by the condenser. This dry, hot air then enters the drying drum (clothes handling drum) through the outlet of the circulating duct. The dry, hot air blows over the wet clothes and carries away the moisture, becoming high-temperature, high-humidity air. This high-temperature, high-humidity air then enters the circulating duct through the inlet. The high-temperature, high-humidity air is condensed by the evaporator, cooling the air and causing the moisture in the air to condense into condensate. The air then becomes low-temperature, dry air. This low-temperature, dry air is then heated by the condenser to become high-temperature, dry air, and then enters the drying drum through the outlet of the circulating duct for circulation, thus drying the clothes.
[0047] Understandably, by installing the impeller assembly 70 in the section between the condenser and the air outlet of the circulating air duct, the dry, high-temperature air heated by the condenser can be delivered to the drying drum (clothes handling drum) at a faster speed, thereby accelerating the rate of moisture loss from the clothes in the drying drum and increasing the drying speed.
[0048] For example, the refrigerant circulation system includes the evaporator, the condenser, and a throttling device. The output end of the evaporator is connected to the input end of the compressor 60, the output end of the compressor 60 is connected to the input end of the condenser, the output end of the condenser is connected to the input end of the throttling device, and the output end of the throttling device is connected to the input end of the evaporator.
[0049] Understandably, in a refrigerant cycle system, the refrigerant needs to complete a thermodynamic cycle process of evaporation (absorbing heat from the outdoor environment) → compression → condensation (releasing heat in the indoor drying room) → throttling → re-evaporation, thereby transferring heat from the low-temperature external environment to the drying drum. The refrigerant circulates within the system under the action of the compressor 60.
[0050] For example, the throttling device is a capillary tube, a thermostatic expansion valve, an electronic expansion valve, or a float throttling valve.
[0051] Please see Figure 1 , Figure 2 and Figure 3 The garment processing equipment 100 also includes a base 80, on which the compressor 60 and the motor 30 are both mounted.
[0052] The clothing processing equipment provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
