[0036] Household washing machines rely on motors for power. As motors run, they generate heat, causing the temperature of the motor's surroundings and the motor itself to rise. Excessive motor temperature can cause motor failure and increase energy consumption. Therefore, effectively dissipating the heat generated by the motor and maintaining it in a specific operating environment can both improve its efficiency and reduce its energy consumption. Currently, the home appliance industry has two solutions for reducing motor operating temperatures:

[0037] 1. Equip the motor with a cooling fan. The rotation of the fan generates wind to take away the surrounding heat to reduce the temperature of the motor.

[0038] 2. Use circulating water to take away the heat generated by the motor to reduce the motor temperature.

[0039] The above two heat dissipation methods have disadvantages:

[0040] 1. Fan cooling cannot efficiently discharge heat from the outside of the machine. A large amount of heat still remains inside the device, and the cooling effect is very limited.

[0041] 2. Circulating water cooling to reduce the temperature of the motor requires a separate circulating water circuit, which involves the sealing and circulation issues of the water circuit, and the manufacturing cost and subsequent repair and maintenance costs are relatively high.

[0042] The present invention provides a washing system and washing equipment to solve the problem of poor heat dissipation of the motor of the existing washing equipment. Figure 1-5 Provide explanation.

[0043] The washing system provided in the embodiment of the present application can be applied to various household washing equipment. For example, please refer to Figure 1 , Figure 1 A schematic structural diagram of the washing system provided in an embodiment of the present application.

[0044] According to one embodiment of the present application, Figure 1 and Figure 2 As shown, the washing system includes a washing drum 5, a motor 4, a compressor 1 and a vortex tube 2. The motor 4 is connected to the washing drum 5 for driving the washing drum 5 to rotate. The vortex tube 2 is connected to the compressor 1. The vortex tube 2 is provided with a cold air outlet 21. The cold air outlet 21 is connected to the cooling pipe 11. The cooling pipe 11 extends to the vicinity of the motor 4 and guides the cold air to blow toward the motor 4; or, the cooling pipe 11 is connected to the motor 4 to dissipate heat from the motor 4.

[0045] It can be understood that in this embodiment, the washing drum 5 is loaded with washing items, and the washing drum 5 can be rotated under the drive of the motor 4, and the washing process is completed through the interaction between the water flow and the system items. The motor 4 can also drive the washing drum 5 to rotate at different speeds or directions to achieve functions such as washing, rinsing and dehydration.

[0046] Vortex heating utilizes a vortex tube 2 to create a vortex in a high-speed airflow, separating it into two streams: cold and hot. This hot air is then used to generate heat. Compressor 1 compresses air into high-pressure gas and delivers it to vortex tube 2. This high-pressure gas passes through vortex tube 2, generating both cold and hot air. Vortex tube 2 has a cold air outlet 21, through which the cold air flows and is delivered to motor 4 via cooling line 11, dissipating heat from the motor.

[0047] The eddy current heating method can be achieved through a purely mechanical structure, without the need for electricity or any chemical substances, and no electric sparks are generated during use. It is small in size, light in weight, simple to manufacture and low in cost, and has rapid cooling and heating. The airflow of the vortex tube 2 directly dissipates heat to the motor 4, with high cooling efficiency, energy saving and environmental protection, and fast cooling speed, which greatly improves the user experience.

[0048] For example, based on the working principle of the vortex tube 2 , the cold air that can be generated can reach a minimum temperature of -46°C and the hot air can reach a maximum temperature of 127°C, which can effectively meet the cooling and heat dissipation requirements of the motor 4 .

[0049] The washing system provided in the embodiment of the present application includes a washing tub 5, a motor 4, a compressor 1, and a vortex tube 2. The motor 4 is connected to the washing tub 5 and is used to drive the washing tub 5 to rotate. The vortex tube 2 is connected to the compressor 1 and is provided with a cold air outlet 21. The cold air outlet 21 is suitable for connecting to the motor 4 through a cooling pipe 11 to dissipate heat from the motor 4. The compressor 1 provides high-pressure gas to the vortex tube 2. After passing through the vortex tube 2, the high-pressure gas can generate cold air and hot air. The cold air can flow out of the cold air outlet 21 and be transported to the motor 4 through the cooling pipe 11 to dissipate heat from the motor 4, effectively reducing the temperature of the motor 4 and improving the heat dissipation effect of the motor 4.

[0050] In an alternative embodiment, see Figure 1 As shown, the cooling pipeline 11 is provided with a fan 3 , which is located between the cold air outlet 21 and the motor 4 . The fan 3 is used to drive the cold air in the cooling pipeline 11 to flow to the motor 4 .

[0051] In an optional embodiment, the washing tub 5 is provided with a heat exchanger 6 , and the vortex tube 2 is further provided with a hot air outlet 22 , which is suitable for being connected to the heat exchanger 6 to exchange heat with the washing water in the washing tub 5 .

[0052] In this embodiment, the vortex tube 2 separates the input compressed air into two parts through the vortex effect inside it. One part is cold air with a lower temperature, which is discharged through the cold air outlet 21 to dissipate heat for the motor 4; the other part is hot air with a higher temperature, which is discharged through the hot air outlet 22. The hot air discharged from the hot air outlet 22 can be heat-exchanged with the water flow in the washing drum 5 through the heat exchanger 6, thereby increasing the water flow temperature in the washing drum 5, improving the washing cleanliness, and also eliminating heat waste, saving energy and being environmentally friendly.

[0053] Optionally, the heat exchange form of the heat exchanger 6 can be fin type heat exchange, or microchannel type or solenoid type heat exchange, etc., as long as it can achieve heat exchange with the water flow in the washing tub 5. This embodiment does not make specific restrictions on this.

[0054] In an alternative embodiment, reference Figure 1 、 Figure 3and Figure 4 As shown, the washing system is also provided with a three-way valve 7, which has a first interface 71, a second interface 72 and a third interface 73. The first interface 71 is connected to the hot gas outlet 22, the second interface 72 is connected to the heat exchanger 6, and the third interface 73 is connected to the external space 8, or the third interface 73 is connected to the inlet end of the compressor 1.

[0055] When the third interface 73 is connected to the external space 8, the hot gas can be discharged into the atmosphere. When the third interface 73 is connected to the inlet end of the compressor 1, the hot gas at the hot gas outlet 22 can flow back to the compressor 1 for recycling.

[0056] The hot gas outlet 22 of the vortex tube 2 can be connected to the first interface 71 of the three-way valve 7. The three-way valve 7 can be controlled by the control module 9 to open the second interface 72 connected to the heat exchanger 6 and close the third interface 73 connected to the atmosphere of the external space 8, or only open the third interface 73 connected to the external space 8 and close the second interface 72 with the heat exchanger 6.

[0057] Specifically, when the three-way valve 7 is only connected to the second interface 72 of the heat exchanger 6, the hot air can heat the washing water in the washing tub 5 through the heat exchanger 6 to improve the washing cleanliness, eliminate heat waste, and save energy and protect the environment.

[0058] Furthermore, the control module 9 can facilitate user operation of the system and can control the operation of the entire washing system. The control module 9 is connected to the motor 4 and can timely monitor the temperature of the motor 4. When the temperature of the motor 4 is detected to be higher than the set value, the control module 9 can adjust the temperature of the cold air outlet 21 by controlling the speed of the compressor 1 and adjusting the flow of the control valve 23 to adjust the temperature of the motor 4.

[0059] In an alternative embodiment, reference Figure 1 As shown, the outlet of the cooling pipe 11 is connected to the external space 8 , and the cold air from the cold air outlet 21 is directly discharged into the atmosphere of the external space 8 after dissipating the heat of the motor 4 .

[0060] In an alternative embodiment, reference Figure 3 As shown, the outlet of the cooling pipe 11 is connected to the inlet end of the compressor 1. The gas after cooling the motor 4 is no longer discharged directly into the atmosphere, but flows back to the air compressor 1 for recycling. This design ensures that no exhaust gas is directly discharged into the environment during the operation of the washing system, thereby ensuring the cleanliness of the user's home environment.

[0061] In an alternative embodiment, reference Figure 4As shown, the outlet of the cooling line 11 is connected to the heat exchanger 6, and the gas after the cooling line 11 merges with the hot gas outlet 22 is connected to the inlet of the compressor 1. There is no need to set a three-way valve 7. The hot gas outlet 22 of the vortex tube 2 is directly connected to the heat exchanger 6, and the gas after cooling the motor 4 is connected to the heat exchanger 6. In other words, the hot air flow generated by the vortex tube 2 and the air flow heated by the motor 4 can both act on the heat exchanger 6 to heat the washing water in the washing tub 5, and then flow back to the compressor 1 for recycling. Therefore, the heat generated by the motor 4 is also fully recycled and utilized, further achieving energy conservation and environmental protection.

[0062] In an alternative embodiment, reference Figure 1 As shown, the vortex tube 2 is provided with a control valve 23, which is configured to adjust the flow rate of the cold air outlet 21 and the hot air outlet 22 to adjust the outlet temperature of the cold air outlet 21 and the hot air outlet 22. By adjusting the opening of the control valve 23, the flow rate of the cold air outlet 21 and the hot air outlet 22 can be adjusted, and the outlet temperature of the cold air outlet 21 and the hot air outlet 22 can be adjusted, thereby adjusting the cooling rate of the motor 4 to adapt to different usage scenarios.

[0063] In an alternative embodiment, reference Figure 1 As shown, the washing system may further include a control module 9, which can control the operation of the entire washing system to facilitate user operation. The controller module can control the speed of the air compressor 1 to adjust the air pressure; the control module 9 can control the rotation of the motor 4 to drive the rotation of the washing drum 5. For example, the control module 9 can adjust parameters such as the rotation direction, rotation time, and rotation speed of the motor 411; the control module 9 can also adjust the control valve 23 to adjust the air flow size of the cold air outlet 21 of the vortex tube 2, thereby adjusting the temperature of the cold air outlet 21; the control module 9 can also control the speed of the fan 3 to adapt to the different cooling requirements of different motors 4.

[0064] In an optional embodiment, the motor 4 is further connected to the compressor 1 to drive the compressor 1 to operate.

[0065] It can be understood that in this embodiment, the motor 4 and the compressor 1 are combined into an integrated component, sharing one motor 4, which can not only realize the air compression function, but also provide the necessary kinetic energy for the washing drum 5, simplifying the system structure and improving energy efficiency.

[0066] In an optional embodiment, the hot air flow from the hot air outlet 22 forms a separate cycle, and the cold air flow from the cold air outlet 21 forms a separate cycle. After the temperatures of the hot air flow and the cold air flow reach the set temperature, they flow back to the compressor 1 for recovery, making the washing system more stable.

[0067] In an optional embodiment, there are multiple vortex tubes 2, and the multiple vortex tubes 2 are arranged in parallel, which can provide more hot air and cold air, increase the cooling speed of the motor 4, and improve work efficiency.

[0068] In an alternative embodiment, reference Figure 5 As shown, the washing system further includes a silencer cover 10 , which is provided to cover at least one of the compressor 1 and the vortex tube 2 .

[0069] Furthermore, in view of the fact that the compressor 1 and the vortex tube 2 may generate relatively loud noise during the washing process, the washing system is provided with a silencer structure, which can silence and reduce the noise of at least one of the compressor 1 and the vortex tube 2, thereby significantly reducing the noise generated by the washing system during operation and improving the user experience.

[0070] For example, the sound-absorbing structure can be implemented in a variety of ways, such as wrapping the outer shell of the compressor 1 and the vortex tube 2 with sound-absorbing materials, or isolating the noise with a physical structure, or adding shock absorbers or silencers to the compressor 1 and the vortex tube 2, etc., as long as it can achieve the effect of reducing noise.

[0071] According to one embodiment of the present application, the sound-absorbing structure includes a sound-absorbing cover 10, which can be installed outside the vortex tube 2 and the compressor 1. The sound-absorbing cover 10 can block or reduce the transmission of noise generated by the compressor 1 and the vortex tube 2 to the outside world. The sound-absorbing cover 10 can be made of a high-density material with good sound absorption properties to effectively absorb and reflect noise, reducing its penetration.

[0072] This embodiment utilizes the characteristic of the vortex tube 2 that it can generate cold air at one end and hot air at the other. The cold air can reach a minimum temperature of -46°C and a maximum temperature of 127°C. The cold air directly cools the motor 4, maintaining it at an efficient operating temperature. This improves the operating efficiency of the motor 4 and reduces its energy loss. It also effectively reduces the risk of motor 4 failure due to high temperature, thereby extending its service life. In addition, the hot air generated by the vortex tube 2 can heat the water flow inside the washing tub 5 to improve washing cleanliness and fully utilize energy.

[0073] In a second aspect, an embodiment of the present application further provides a washing device, which includes a washing system as described in the above embodiment.

[0074] It is understandable that the washing equipment of this embodiment may include but is not limited to drum washing machines, pulsator washing machines, washer-dryers, shoe washing machines, dishwashers and other household appliances.

[0075] It can be understood that if the washing system has the beneficial effects of the above embodiments, then the washing equipment will correspondingly have the beneficial effects of the above embodiments. Its specific implementation can refer to the above embodiments, and this embodiment will not elaborate on it.

[0076] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0077] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be covered by the scope of protection of the present application.
