[0041] This application provides a motor cooling system and a clothes handling device to solve the problems that existing washing machine motors can easily cause when they overheat, leading to decreased motor performance, increased energy consumption, shortened lifespan, and safety hazards. The following description is in conjunction with the accompanying drawings.
[0042] The motor cooling system provided in this embodiment is applied to a garment processing device. The garment processing device includes a motor 3, and the motor cooling system includes a compressor 1 and an air amplifier 2. Please refer to [link / reference]. Figure 1 , Figure 1 The first structural schematic diagram of the motor cooling system provided in this application embodiment shows that the compressor 1 includes an outlet end 12 for outputting compressed gas; the air amplifier 2 includes an inlet 22, an intake port 21 and an outlet 23, the inlet 22 is connected to the outlet end 12 and the outlet 23 is used to discharge air to the motor 3; wherein, the compressed gas enters the air amplifier 2 to create a negative pressure at the intake port 21 and draw in air, which then flows out through the outlet 23.
[0043] The motor cooling system provided in this embodiment uses a compressor 1 to provide a power source for an air amplifier 2. Compressed gas output from the outlet 12 of the compressor 1, acting as the power source, enters the air amplifier 2 through the inlet 22 and forms a negative pressure zone at the intake 21, drawing in a large amount of air. The air drawn in through the intake 21 mixes with the compressed gas inside the air amplifier 2 to form a high-speed, high-pressure airflow, which is then sprayed from the outlet 23 towards the motor 3. The flow rate of the high-speed, high-pressure gas ejected from the outlet 23 is typically 10 to 100 times that of the compressed gas. This utilizes the wall adhesion effect to efficiently carry away the heat generated by the motor 3, thereby reducing the temperature of the motor 3 and preventing a series of problems caused by overheating. Furthermore, the air amplifier 2 has no moving parts, a simple and reliable structure, and low maintenance costs.
[0044] The type of compressor 1 is not further limited here; for example, it can be a centrifugal compressor, a screw compressor, a reciprocating compressor, etc.
[0045] Understandably, the motor 3 of the clothing processing equipment is mainly used to drive the washing drum 4 to rotate, thereby realizing the washing or dehydration of clothes. There are many types of motor 3, such as DC brushless motor, AC induction motor, permanent magnet synchronous motor or direct drive motor, series motor, etc.
[0046] Optionally, please refer to Figure 2 , Figure 2 This is a second structural schematic diagram of the motor cooling system provided in this application embodiment. The motor cooling system provided in this application embodiment also includes a first temperature detection element, which is disposed on the motor 3; the compressor 1 is used to adjust the airflow at the outlet 12 according to the detection result of the first temperature detection element. In some examples, the first temperature detection element can be a temperature sensor, and the model of the temperature sensor is not further limited here. Specifically, the clothing processing device includes a main board 7, which is communicatively connected to the first temperature detection element and the compressor 1 respectively. The main board 7 receives the detection result of the first temperature detection element and controls the flow rate adjustment at the outlet 12 of the compressor 1.
[0047] The temperature of motor 3 is detected by a first temperature sensor. Based on the detection result, the airflow at the outlet 12 of compressor 1 is adjusted to keep the temperature of motor 3 within a preset temperature range. This preset temperature range is not further limited; it is sufficient for motor 3 to operate efficiently within this range. For example, when the detection result of the first temperature sensor is within the first temperature range, the airflow at the outlet 12 of compressor 1 is increased; when the detection result of the first temperature sensor is within the second temperature range, the airflow at the outlet 12 of compressor 1 is decreased; when the detection result of the first temperature sensor is within the preset temperature range, compressor 1 is turned off, meaning that the temperature of motor 3 has reached the ideal preset temperature range and no further cooling is needed, hence compressor 1 is turned off. The values within the first temperature range are all greater than the values within the second temperature range, and the values within the second temperature range are all greater than the values within the preset temperature range.
[0048] Optionally, the motor cooling system provided in this embodiment further includes a first pipe 9, which connects the air outlet 23 and the motor 3. That is, by setting the first pipe 9, the high-speed, high-pressure gas ejected from the air outlet 23 is guided to the motor 3, reducing the pressure loss of the high-speed, high-pressure gas during the blowing process of the motor 3, improving the heat exchange efficiency between the high-speed, high-pressure gas and the motor 3, and accelerating the cooling rate of the motor 3.
[0049] Furthermore, a heat exchange chamber (not shown in the figure) may be provided on the periphery of the motor 3. The heat exchange chamber is used to exchange heat with the motor 3. The first pipe 9 connects the heat exchange chamber and the air outlet 23.
[0050] In some examples, the heat exchange chamber is provided with an opening that communicates with the atmosphere 8. The high-speed, high-pressure gas ejected from the outlet 23 enters the heat exchange chamber through the first pipe 9 and exchanges heat with the motor 3. Then, it can be discharged directly into the atmosphere 8 through the opening on the heat exchange chamber.
[0051] Optionally, please refer to Figure 3 , Figure 3 This is a third structural diagram of the motor cooling system provided in this application embodiment. The motor cooling system provided in this application embodiment further includes a second pipe 10 and a first heat exchanger 5. One end of the second pipe 10 is connected to the motor 3; the first heat exchanger 5 includes an adjacent gas flow channel and a liquid flow channel. The liquid flow channel is connected to the washing solution in the laundry processing equipment, and the gas flow channel is connected to the other end of the second pipe 10; wherein, the gas flow channel is used to exchange heat with the liquid flow channel to heat the liquid in the liquid flow channel. Specifically, the end of the second pipe 10 near the motor 3 can be connected to the heat exchange chamber.
[0052] By setting up a first heat exchanger 5, heat from the gas exchanged with the motor 3 is recovered. This heat is then used to further heat the washing solution in the washing drum 4 of the garment processing equipment, thereby increasing the foaming rate and enzyme activity of the detergent, thus improving the cleaning ability of the washing solution and the cleanliness of the clothes to be washed. This not only improves the utilization rate of gas heat but also avoids directly discharging high-temperature gas into the atmosphere 8, preventing interference with the operation of other systems.
[0053] The type of the first heat exchanger 5 is not further limited here. In some examples, the first heat exchanger 5 can be a tubular heat exchanger; in other examples, it can be a plate heat exchanger; and in still other examples, it can be a finned heat exchanger. No further examples are given here; any heat exchanger that can heat the internal fluid via hot air is considered the first heat exchanger 5. The location of the first heat exchanger 5 is also not further limited; it can be located inside or outside the garment processing equipment, as long as it can achieve the heating effect on the washing solution inside the washing drum 4.
[0054] As a specific implementation, the gas flow channel of the first heat exchanger 5 can be provided with an outlet connected to the atmosphere 8 at the end away from the second pipe 10. That is, after the gas exchanged heat with the motor 3 enters the gas flow channel in the first heat exchanger 5, it reheats the liquid in the liquid flow channel in the first heat exchanger 5, and then is discharged into the atmosphere 8 through the outlet of the gas flow channel.
[0055] Optionally, the motor cooling system provided in this embodiment further includes a second temperature detection element, which is used to detect the temperature of the washing solution; the first heat exchanger 5 adjusts the flow rate in the gas channel according to the detection result of the second temperature detection element. Specifically, the second temperature detection element can be a temperature sensor.
[0056] The heating effect of the first heat exchanger 5 on the washing solution in the garment processing equipment can be controlled by adjusting the flow rate in the gas channel. Specifically, when the detection result of the second temperature sensor falls within the first temperature range, the gas channel and the liquid channel exchange heat to heat the liquid in the liquid channel; when the detection result of the second temperature sensor falls within the second temperature range, the gas channel and the liquid channel do not exchange heat, and the washing solution in the garment processing equipment is not heated. When the detection result of the second temperature sensor falls within the first temperature range, it indicates that the temperature of the washing solution is low, requiring heating by the first heat exchanger 5 to improve the washing effect; when the detection result of the second temperature sensor falls within the second temperature range, it indicates that the temperature of the washing solution is suitable, and the washing solution can achieve a good washing effect without heating. When the detection result of the second temperature sensor falls within the second temperature range, the washing solution in the garment processing equipment can be disconnected from the liquid channel, thus not exchanging heat with the gas channel. It can be understood that the values in the second temperature range are all greater than the values in the first temperature range.
[0057] Furthermore, when the detection result of the second temperature sensor falls within the first temperature range, the flow rate in the gas channel can be approximately inversely proportional to the detection result of the second temperature sensor. That is, the lower the temperature of the washing solution, the greater the flow rate in the gas channel, in order to quickly raise the temperature of the washing solution; conversely, the higher the temperature of the washing solution, the smaller the flow rate in the gas channel. As a specific implementation, the first temperature range can be divided into multiple temperature ranges, each temperature range corresponding to a specific flow rate value in the gas channel. The specific flow rate value of the gas channel corresponding to that temperature range is directly determined based on the temperature range corresponding to the detection result of the second temperature sensor. Further examples of the specific values for the multiple temperature ranges are not provided here.
[0058] Optionally, please refer to Figure 4 , Figure 4 This is a fourth structural diagram of the motor cooling system provided in this application embodiment. The motor cooling system provided in this application embodiment also includes a second heat exchanger 6, which connects the gas flow channel and the suction port 21. The second heat exchanger 6 is used to cool the gas output from the gas flow channel to a preset temperature and to direct the gas at the preset temperature to the suction port 21. The value of the preset temperature is not further limited here.
[0059] By setting up a second heat exchanger 6, the gas discharged from the gas flow channel of the first heat exchanger 5 is cooled down again, and the cooled gas is used to supply air to the air intake 21 of the air amplifier 2, realizing the recycling of gas. There is no need to exhaust gas into the atmosphere 8, protecting the user's home environment from pollution by the exhaust gas, and fully recovering and utilizing system energy to reduce energy consumption.
[0060] In some examples, the second heat exchanger 6 can be a shell-and-tube heat exchanger; in some examples, the second heat exchanger 6 can be a plate heat exchanger; in some examples, the second heat exchanger 6 can be an air cooler; in some examples, the second heat exchanger 6 can be a spiral plate heat exchanger; in some examples, the second heat exchanger 6 can be a tube bundle heat exchanger; in some examples, the second heat exchanger 6 can be a plate-fin heat exchanger. Any heat exchanger capable of cooling the gas discharged from the gas flow channel of the first heat exchanger 5 is acceptable; further examples are not provided here.
[0061] Optionally, the compressor 1 also includes an inlet end 11, and the second heat exchanger 6 is connected to the gas flow channel and the inlet end 11. The second heat exchanger 6 is used to cool the gas output from the gas flow channel to a preset temperature and to pass the gas at the preset temperature to the inlet end 11.
[0062] The second heat exchanger 6 can also supply air to the air inlet 11 of the compressor 1, realizing closed-loop control of the entire motor cooling system, further reducing the impact of the motor cooling system on the surrounding environment of the clothing processing equipment, and improving the user experience.
[0063] Optionally, the motor cooling system provided in this embodiment further includes a third pipe and a regulating valve. The third pipe includes a first connecting port, a second connecting port, and a third connecting port, which are respectively connected to the second heat exchanger 6, the suction port 21, and the inlet end 11; the regulating valve is disposed in the third pipe to regulate the flow rate at the second connecting port and the third connecting port. Specifically, the regulating valve is a flow regulating valve, and the type of flow regulating valve is not further limited here. For example, it can be a butterfly valve, a ball valve, a needle valve, a throttle valve, a gate valve, a pressure regulating valve, or an automatic regulating valve, etc.
[0064] By installing a regulating valve in the third pipe, the gas flow rate at the second and third connecting ports can be controlled, making the gas flow rate supplied from the second heat exchange chamber to the air amplifier 2 and compressor 1 controllable. The parameters of the regulating valve can be set according to the gas flow rate requirements of the air amplifier 2 and compressor 1. The number of regulating valves is not further limited here. In some examples, there can be only one regulating valve, located at either the second or third connecting port. Since the second and third connecting ports are interconnected and the flow rate in the third pipe is constant, adjusting the flow rate at one of the connecting ports can regulate the flow rate at both the second and third connecting ports. In other examples, there can be two regulating valves, one located at the second connecting port and the other at the third connecting port. The flow rate at the corresponding location is specifically adjusted by setting the parameters of each regulating valve.
[0065] Optionally, the air amplifier 2 includes multiple air amplifiers, each of which can supply air to the motor 3. The air outlet 12 can output compressed gas to one or more of the air amplifiers 2. By increasing the number of air amplifiers 2, the air supply to the motor 3 is increased, further improving the cooling efficiency of the motor 3. The number of compressors 1 is not further limited here; it can be one or more. When there are multiple compressors 1, the compressors 1 and air amplifiers 2 can be set up in a one-to-one correspondence.
[0066] Optionally, the garment processing equipment also includes a main board 7, which can be electrically connected to the first temperature sensor, the second temperature sensor, the compressor 1, and the first heat exchanger 5. The main board 7 controls the air output of the compressor 1 at the outlet 12 according to the detection result of the first temperature sensor, and also controls the flow rate in the gas channel of the first heat exchanger 5 according to the detection result of the second temperature sensor.
