Description

Technical Field

[0001] This application relates to the field of clothing processing equipment technology, and more particularly to a clothing processing device. Background Technology

[0002] With the improvement of living standards, washing machines with partitioned washing function have become an important feature for families when choosing a washing machine. Multi-drum washing machines with partitioned washing function have appeared on the market, with each drum having washing and drying functions.

[0003] To ensure effective drying of wet clothes, current multi-drum washing machines are equipped with heat pump systems in each drum to condense the humid air and then heat the condensed air to dry the clothes. However, the manufacturing cost of current multi-drum washing machines is relatively high. Utility Model Content

[0004] This application discloses a garment processing device that can reduce the manufacturing cost of garment processing devices.

[0005] To achieve the above objectives, embodiments of this application disclose a garment processing device, comprising:

[0006] The box contains:

[0007] Multiple spaced-apart rollers, each roller having a cavity for holding clothes, and each roller having a drying air inlet and a drying air outlet;

[0008] Drying air duct, including:

[0009] Main air duct;

[0010] Multiple air inlet branch ducts are provided, each of which is connected to the main air duct in a way that can be switched on and off, and each of which is connected to the drying air inlet of the corresponding drum.

[0011] Multiple air outlet branch ducts are provided, each of which is connected to the main air duct in a way that can be switched on and off, and each of the air outlet branch ducts is connected to the drying air outlet of the corresponding drum.

[0012] The first fan is located in the drying air duct so that air enters the accommodating cavity from the drying air inlet and is discharged from the drying air outlet, while the air flows in the main air duct along the first preset air direction.

[0013] Heat pump systems include:

[0014] compressor;

[0015] The first condenser is located inside the main air duct;

[0016] An evaporator is located in the main air duct along the first preset air direction, and the first condenser is located downstream of the evaporator. The evaporator, the first condenser, and the compressor are connected in series.

[0017] An electric heater is provided in the drying air duct, and the electric heater is located downstream of the evaporator along the first preset air direction to heat the air entering the receiving cavity of each of the rollers.

[0018] In this application, a first condenser and an evaporator are installed in the main air duct. The drying air formed after passing through the evaporator and the first condenser can enter each inlet branch air duct, and then enter each drum through each drying air inlet to remove moisture from the clothes, forming humid and hot air. The humid and hot air can return to the main air duct through each outlet branch air duct, and then pass through the evaporator and the first condenser in sequence to form drying air, thus circulating and drying. It can be seen that this application places the evaporator and the first condenser of the same heat pump system in the main air duct, which can dry the clothes in each drum. This eliminates the need to configure a heat pump system for each drum, thereby reducing the manufacturing cost of the clothes processing equipment.

[0019] Furthermore, the drying duct of this application is equipped with an electric heater, which is located downstream of the evaporator along a first preset airflow direction, thereby heating the air entering the receiving chambers of each drum. It is evident that the drying duct of this application contains both an electric heater and a first condenser. Both the electric heater and the first condenser can heat the dry air entering the drying duct, thus accelerating the initial temperature rise. This is because a heat pump system requires a certain amount of time to reach the target temperature from a cold start, while the electric heater's heating rate is much faster. Therefore, adding an electric heater can quickly raise the air temperature in the initial stage, allowing the air to rapidly reach the target temperature, shortening the preheating time, thereby improving the drying effect on clothes and shortening the drying time. In addition, when the clothes have high moisture content and a high humidity load, the electric heater can instantly provide additional heat, preventing a decrease in drying efficiency due to insufficient power of the heat pump system.

[0020] In one optional embodiment, the number of electric heaters is multiple, and each of the air inlet branch ducts is provided with an electric heater; and / or, the main air duct is provided with an electric heater, and along the first preset air direction, the electric heater provided in the main air duct is located downstream of the first condenser.

[0021] Since each air inlet branch duct is close to the corresponding drum cavity, this application places each electric heater in each air inlet branch duct. This allows the electric heater to be closer to the corresponding cavity, shortening the path of the air heated by the electric heater into the corresponding cavity, reducing heat loss when the air heated by the electric heater enters the cavity, and ensuring that the air has a higher temperature when in contact with the clothes, thereby improving the drying effect on the clothes.

[0022] In addition, the main air duct is equipped with an electric heater, so that the air heated by the electric heater on the main air duct can enter each air inlet branch air duct. In other words, with the structure of this embodiment, only one electric heater needs to be installed in the main air duct to heat the air entering the receiving cavity of each roller, thereby reducing the number of electric heaters required and further saving the manufacturing cost of the garment processing equipment.

[0023] In an optional embodiment, the drying duct further includes:

[0024] The air inlet connecting duct is connected to the outlet of the main air duct, and each of the air inlet branch ducts is connected to the air inlet connecting duct in a way that can be switched on and off.

[0025] The air outlet connecting duct is connected to the inlet of the main air duct, and each of the air outlet branch ducts is connected to the air outlet connecting duct in a way that can be switched on and off.

[0026] In this embodiment, the drying air duct includes an inlet connecting air duct that is connected to the main air duct. Each inlet branch air duct is connected to the inlet connecting air duct. In other words, each inlet branch air duct is connected to the main air duct through the inlet connecting air duct, thus eliminating the need to connect each inlet branch air duct to the main air duct, thereby simplifying the ductwork structure. Furthermore, the drying air duct includes an outlet connecting air duct that is connected to the main air duct. Each outlet branch air duct is connected to the outlet connecting air duct. In other words, each outlet branch air duct is connected to the main air duct through the outlet connecting air duct, thus eliminating the need to connect each outlet branch air duct to the main air duct, thereby simplifying the ductwork structure.

[0027] In an optional embodiment, the housing further includes:

[0028] A second fan is provided in at least one of the air inlet branch ducts.

[0029] In this embodiment, at least one air inlet branch duct is equipped with a second fan. Turning on the second fan can increase the air volume of the drying air entering the air inlet branch duct where the second fan is located, thereby improving the drying effect on the clothes in the corresponding drum. Therefore, selectively turning on or off the operation of a certain second fan can meet the different air volume requirements of the clothes in different drums.

[0030] Furthermore, the long-distance transport and turning of the drying air can cause a drop in air pressure, affecting the drying effect. Therefore, setting a second fan in at least one air inlet branch can increase the air pressure and ensure that the drying air can be input into the drum, thus guaranteeing the drying effect on the clothes.

[0031] In one optional embodiment, all of the air inlet branch ducts, except for the one closest to the main air duct, are equipped with a second fan.

[0032] In this embodiment, the air inlet branch duct closest to the main air duct is not equipped with a second fan. Since the air pressure loss when the air flows from the main air duct to the nearest air inlet branch duct is small, even if a second fan is not installed in the air inlet branch duct, the roller corresponding to the air inlet branch duct can still have a large drying air volume, thereby achieving the purpose of saving the manufacturing cost of the clothing processing equipment.

[0033] In an optional embodiment, the housing further includes:

[0034] A third fan is provided in the air outlet connecting duct, and the third fan is located between the two air outlet branch ducts that are closest to the main duct.

[0035] In this embodiment, a third fan is provided in the air outlet connecting duct. Turning on the third fan can quickly exhaust the hot and humid air from the drum and into the air outlet branch duct, thereby improving the air circulation efficiency and the drying effect on the clothes in the corresponding drum.

[0036] In one optional embodiment, the number of compressors is one, and the heat pump system further includes:

[0037] A second condenser is provided in the air inlet connecting duct, and the second condenser is located between the two air inlet branch ducts that are closest to the main air duct.

[0038] In this embodiment, the second condenser is located in the air inlet connecting duct and between the two air inlet branch ducts closest to the main air duct. When the drying air heated by the first condenser passes through the second condenser, it will be heated again to increase the air temperature. In this way, even if the drying air is transported over a long distance, the drying air can be kept at a high temperature, thereby improving the drying effect on clothes.

[0039] Furthermore, in this embodiment, the first condenser and the second condenser share the same compressor. Compared with the embodiment where each of the first condenser and the second condenser is equipped with a separate compressor, this embodiment can reduce the number of compressors, thereby reducing the cost of the clothing processing equipment, saving space inside the box, and reducing the weight and volume of the clothing processing equipment.

[0040] In one alternative embodiment, the first fan is located between the first condenser and the evaporator.

[0041] In this embodiment, the first fan is located upstream of the first condenser and downstream of the evaporator. The first fan draws air from the evaporator side, continuously drawing air through the cold evaporator to quickly remove condensed moisture, preventing frost buildup on the evaporator due to low temperatures and ensuring continuous and efficient heat exchange. Furthermore, the first fan directs air towards the first condenser. Compared to having the first fan upstream of the evaporator, this embodiment allows heated air to penetrate the clothing at higher pressure and flow rate, resulting in more uniform airflow distribution and more thorough heat exchange, ensuring optimal drying performance.

[0042] In one alternative embodiment, the housing includes:

[0043] The front panel is provided with a first garment inlet, a second garment inlet, and a third garment inlet; the plurality of rollers include:

[0044] The first roller, the opening of the first roller is opposite to the first clothes inlet;

[0045] The second roller, the opening of which is opposite to the second garment inlet;

[0046] The third roller, the opening of which is opposite to the third garment inlet;

[0047] The front panel is a one-piece structure.

[0048] In this embodiment, the garment processing equipment includes a large first roller, two small second rollers, and a third roller. The second and third rollers are arranged side by side in the box at intervals along the width direction of the box. The first, second, and third rollers can all operate independently, thereby realizing zoned washing. Zoned washing can separate garments with different washing requirements for washing. For example, underwear and other intimate clothing can be washed separately from outerwear, socks, and other clothing to avoid cross-contamination and ensure the washing quality of the garments.

[0049] Secondly, this application provides a garment processing device, comprising:

[0050] The box contains:

[0051] Multiple spaced outer cylinders;

[0052] Multiple rollers are rotatably disposed within each of the outer cylinders, and each roller has a receiving cavity for accommodating clothing. The multiple rollers include:

[0053] First roller;

[0054] The second roller is positioned higher than the first roller, and the diameter of the second roller is smaller than the diameter of the first roller.

[0055] Multiple independent drying air ducts are respectively located outside each of the rollers. The inlet and outlet of each drying air duct are connected to the receiving cavity of the roller to form a circulation loop.

[0056] Multiple air supply fans are respectively installed in each of the aforementioned drying air ducts;

[0057] Heat pump systems include:

[0058] compressor;

[0059] The first condenser is located in the drying air duct corresponding to the first drum;

[0060] An evaporator is disposed in the drying air duct corresponding to the first drum. Along the airflow direction in the drying air duct, the first condenser is located downstream of the evaporator. The evaporator is connected in series with the compressor and the first condenser.

[0061] Multiple electric heaters are respectively installed inside each of the aforementioned drying air ducts;

[0062] A straight exhaust pipe is connected to the outer cylinder sleeved outside the second roller to exhaust the hot and humid air inside the outer cylinder.

[0063] In this embodiment, the first drum, with its larger diameter, holds more clothes and generates a larger flow of humid air during drying. Therefore, an evaporator is used to condense the humid air, and the condensed dry air is reheated and then fed back into the first drum. This avoids directly venting large amounts of humid air into the customer's home, preventing a damp environment that could harm the customer's health or damage their furniture. Conversely, the second drum, with its smaller diameter, holds fewer clothes and generates a smaller flow of humid air during drying. Therefore, even if the humid air were discharged into the customer's home through a direct exhaust pipe, the impact on the customer would be negligible. This reduces the manufacturing cost and size of the clothing processing equipment. Attached Figure Description

[0085] With the improvement of living standards, washing machines with partitioned washing function have become an important feature for families when choosing a washing machine. Multi-drum washing machines with partitioned washing function have appeared on the market, with each drum having washing and drying functions.

[0086] To ensure effective drying of wet clothes, current multi-drum washing machines are equipped with heat pump systems in each drum to condense the humid air and heat the condensed dry air to dry the wet clothes. Each independent heat pump system has a compressor, meaning that current multi-drum washing machines contain multiple compressors. The manufacturing cost of compressors is relatively high, which leads to the higher manufacturing cost of multi-drum washing machines.

[0087] The clothing processing equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0088] like Figures 1 to 4As shown in the illustration, this application discloses a garment processing device. Exemplarily, this garment processing device can be a washer-dryer combo or a dryer, and includes:

[0089] Box 100.

[0090] Specifically, the housing 100 is used to form the overall appearance of the garment processing equipment. The interior of the housing 100 is hollow to form a storage space, which is configured to accommodate multiple components in the garment processing equipment, such as circuits, drive components, and drainage components. The housing 100 can be rectangular to be placed close to a wall; of course, the housing 100 can also be cylindrical to match the circular components inside the garment processing equipment.

[0091] The box 100 contains:

[0092] Multiple spaced rollers 200, each roller 200 having a receiving cavity 201 for holding clothes, and each roller 200 having a drying air inlet and a drying air outlet 202.

[0093] Specifically, the drying air inlet can be the opening of the drum 200, and the drying air outlet 202 can be located on the bottom wall of the drum 200. Specifically, each drum 200 is also fitted with an outer cylinder 700, which can be mounted in the housing 100 via a suspension spring. A ventilation cavity 701, communicating with the drying air outlet, is formed between the bottom wall of the outer cylinder 700 and the bottom wall of the drum 200. The ventilation cavity 701 is connected to the air outlet branch duct 330 described below.

[0094] Drying air duct 300, including:

[0095] The main air duct 310 is used to house the evaporator 530 and the first condenser 520, as described below.

[0096] Multiple air inlet branch ducts 320 are provided, each of which is connected to the main air duct 310 in a way that can be switched on or off. Each air inlet branch duct 320 is connected to the drying air inlet of the corresponding drum 200.

[0097] Specifically, the air discharged from the main air duct 310 can selectively enter each air inlet branch air duct 320, and then enter the receiving cavity 201 of each roller 200. For example, an air inlet valve 810 can be installed in each air inlet branch air duct 320 to achieve the purpose of allowing each air inlet branch air duct 320 to be connected to the main air duct 310 in a way that can be switched on and off.

[0098] Multiple air outlet branch ducts 330 are provided, each of which is connected to the main air duct 310 in a way that can be switched on or off. Each air outlet branch duct 330 is connected to the drying air outlet 202 of the corresponding drum 200.

[0099] Specifically, the air discharged from each roller 200 can enter each outlet branch duct 330 and then return to the main duct 310. For example, an outlet valve 820 can be installed in each outlet branch duct 330 to achieve the purpose of allowing each outlet branch duct 330 to be connected to the main duct 310 in a way that can be switched on and off.

[0100] The first fan 410 is installed in the drying air duct 300 so that the drying air in the drying air duct 300 flows along the first preset air direction.

[0101] Specifically, the first fan 410 can circulate air in the main air duct 310, the inlet branch air duct 320, the accommodating cavity 201, and the outlet branch air duct 330. For example, the fan here can be a centrifugal fan, an axial fan, etc., and this application does not limit it to this.

[0102] Heat pump system 500, including:

[0103] Compressor 510 is used to compress refrigerant.

[0104] The first condenser 520 is located in the main air duct 310 and is used to liquefy the refrigerant in the heat pump system 500.

[0105] Evaporator 530 is located in the main air duct 310 along the first preset air direction. First condenser 520 is located downstream of evaporator 530. Evaporator 530, first condenser 520 and compressor 510 are connected in series.

[0106] Specifically, the heat pump system 500 may also include an expansion valve 550, which is connected in series between the condenser and the evaporator 530. The expansion valve 550 is used to regulate the flow rate of the refrigerant to reduce the pressure of the refrigerant and change the boiling point of the refrigerant. The evaporator 530 here has a fluid passage for introducing the refrigerant, which is connected in series with the condenser and the compressor 510.

[0107] Specifically, after the refrigerant is discharged from the refrigerant outlet of the compressor 510, it can enter the refrigerant inlet of the condenser through the refrigerant pipeline, and then enter the condenser. In the condenser, it releases heat, allowing it to heat the surrounding air. The air, heated by the condenser, then enters the containment chamber 201, where it can dry clothes. Afterward, the refrigerant is discharged from the refrigerant outlet of the condenser and enters the expansion valve 550. Under the action of the expansion valve 550, the refrigerant pressure is reduced, and then it enters the refrigerant inlet of the evaporator 530. In the evaporator 530, the refrigerant absorbs heat, allowing the evaporator 530 to cool the surrounding air. The humid, hot air discharged from the containment chamber 201 cools down under the action of the evaporator 530, causing moisture to precipitate and form water droplets. A drainage structure can be installed at a corresponding position on the evaporator 530 to collect and discharge the water droplets. Finally, the refrigerant is discharged from the refrigerant outlet of the evaporator 530 and re-enters the compressor 510 from the refrigerant inlet.

[0108] It is worth noting that the number of rollers 200 can be 2 or 3. The number of rollers 200 can also be more, which will not be elaborated here.

[0109] An electric heater 600 is provided in the drying air duct 300. The electric heater 600 is located downstream of the evaporator 530 along the first preset air direction to heat the air entering the receiving cavity 201 of each roller 200.

[0110] In this application, a first condenser 520 and an evaporator 530 are provided in the main air duct 310. The drying air formed after passing through the evaporator 530 and the first condenser 520 can enter each air inlet branch duct 320, and then enter each roller 200 through each drying air inlet to remove moisture from the clothes, forming humid and hot air. The humid and hot air can return to the main air duct 310 through each air outlet branch duct 330, and then pass through the evaporator 530 and the first condenser 520 in sequence to form drying air, thus circulating and drying. It can be seen that by placing the evaporator 530 and the first condenser 520 of the same heat pump system 500 in the main air duct 310, the clothes in each roller 200 can be dried. In this way, it is not necessary to configure a heat pump system 500 for each roller 200, thereby reducing the manufacturing cost of the clothes processing equipment.

[0111] Furthermore, the drying duct 300 of this application is also equipped with an electric heater 600. The electric heater 600 is located downstream of the evaporator 530 along a first preset airflow direction, thereby heating the air entering the receiving cavity 201 of each roller 200. It can be seen that the drying duct 300 of this application is equipped with both an electric heater 600 and a first condenser 520. Both the electric heater 600 and the first condenser 520 can heat the dry air entering the drying duct 300, thus accelerating the initial temperature rise. This is because the heat pump system 500 requires a certain amount of time to reach the target temperature from a cold start, while the heating speed of the electric heater 600 is much faster than that of the heat pump system 500. Therefore, the addition of the electric heater 600 can quickly increase the air temperature in the initial stage, allowing the air to quickly reach the target temperature, shortening the preheating time, improving the drying effect on clothes, and shortening the drying time. In addition, when the clothes have high moisture content and high humidity load, the electric heater 600 can provide extra heat instantly to prevent the drying efficiency from decreasing due to insufficient power of the heat pump system 500.

[0112] In some embodiments, the housing 100 can be an integral housing, that is, multiple rollers 200 are disposed in the same housing 100, which can improve the shock absorption performance; or the housing 100 can also be a split housing, that is, the housing 100 can include two sub-housings, and multiple rollers 200 are respectively placed in the two sub-housings. For example, the rollers 200 with larger cylinder diameters are placed in one sub-housing, and the other rollers 200 with smaller cylinder diameters are placed in the other sub-housing.

[0113] In some embodiments, the electric heater 600 may be installed only in the main air duct 310, instead of in the air inlet branch air duct 320. This reduces the number of electric heaters 600 installed and further saves on the manufacturing cost of the garment processing equipment.

[0114] Please see Figures 2 to 4 In one optional embodiment, there are multiple electric heaters 600, and each air inlet branch duct 320 is provided with an electric heater 600.

[0115] Specifically, since each air inlet branch duct 320 is close to the corresponding receiving cavity 201 of the drum 200, this application sets each electric heater 600 in each air inlet branch duct 320. This allows the electric heater 600 to be closer to the corresponding receiving cavity 201, shortening the path of the air heated by the electric heater 600 into the corresponding receiving cavity 201, reducing heat loss when the air heated by the electric heater 600 enters the receiving cavity 201, and ensuring that the air has a higher temperature when in contact with the clothes, thereby improving the drying effect on the clothes.

[0116] In one optional embodiment, the main air duct 310 is provided with an electric heater 600, and along the first preset air direction, the electric heater 600 in the main air duct 310 is located downstream of the first condenser 520. At this time, the air in the main air duct 310 passes through the evaporator 530, the first condenser 520 and the electric heater 600 in sequence before entering each air inlet branch air duct 320.

[0117] Specifically, the main air duct 310 is equipped with an electric heater 600. The air heated by the electric heater 600 on the main air duct 310 can enter each air inlet branch air duct 320. In other words, with the structure of this embodiment, only one electric heater 600 needs to be installed in the main air duct 310 to heat the air entering the receiving cavity 201 of each roller 200, thereby reducing the number of electric heaters 600 and further saving the manufacturing cost of the garment processing equipment.

[0118] In some embodiments, the air flowing out of the main air duct 310 enters the air inlet connecting air duct 340, and can then be distributed by the air inlet connecting air duct 340 to each air inlet branch air duct 320. Alternatively, each air outlet branch air duct 330 can be connected to the main air duct 310, and each air outlet branch air duct 330 can be connected to the main air duct 310.

[0119] To simplify the piping structure of garment handling equipment, please refer to [link / reference]. Figures 2 to 4 In an optional embodiment, the drying duct 300 further includes:

[0120] The air inlet connecting duct 340 is connected to the outlet of the main air duct 310, and each air inlet branch duct 320 is connected to the air inlet connecting duct 340 in a detachable manner.

[0121] Specifically, the air flowing out of the main air duct 310 will enter the air inlet branch air duct 320, and then enter each roller 200.

[0122] The air outlet connecting duct 350 is connected to the inlet of the main air duct 310, and each air outlet branch duct 330 is connected to the air outlet connecting duct 350 in a way that can be switched on and off.

[0123] Specifically, the air flowing out of the drying air outlet of each roller 200 will enter the air outlet branch duct 330 respectively, and then merge into the air outlet connecting duct 350 to enter the main air duct 310.

[0124] In this embodiment, the drying air duct 300 includes an air inlet connecting air duct 340 that is connected to the main air duct 310. Each air inlet branch air duct 320 is connected to the air inlet connecting air duct 340. That is to say, each air inlet branch air duct 320 is connected to the main air duct 310 through the air inlet connecting air duct 340. In this way, it is not necessary to connect each air inlet branch air duct 320 to the main air duct 310, thereby simplifying the pipeline structure.

[0125] Furthermore, the drying air duct 300 includes an air outlet connecting air duct 350 connected to the main air duct 310, and each air outlet branch air duct 330 is connected to the air outlet connecting air duct 350. In other words, each air outlet branch air duct 330 is connected to the main air duct 310 through the air outlet connecting air duct 350, so there is no need to connect each air outlet branch air duct 330 to the main air duct 310, thereby simplifying the pipeline structure.

[0126] To meet the different airflow requirements of different garments in the 200mm drum, please refer to [link / reference]. Figures 2 to 4 In one optional embodiment, the housing 100 further includes:

[0127] The second fan 420 is provided in at least one air inlet branch duct 320.

[0128] Specifically, only some of the air inlet branch ducts 320 may be equipped with a second fan 420, or all of the air inlet branch ducts 320 may be equipped with a second fan 420, or none of the air inlet branch ducts 320 may be equipped with a second fan 420.

[0129] Specifically, at least one air inlet branch duct 320 is equipped with a second fan 420. Turning on the second fan 420 can increase the air volume of the drying air entering the air inlet branch duct 320 where the second fan 420 is located, thereby improving the drying effect on the clothes in the corresponding drum 200. Therefore, selectively turning on or off the operation of a certain second fan 420 can meet the different air volume requirements of the clothes in different drums 200.

[0130] Furthermore, the long-distance transport and turning of the drying air will cause a drop in air pressure, which will affect the drying effect. Therefore, setting a second fan 420 in at least one air inlet branch duct 320 can increase the air pressure and ensure that the drying air can be input into the drum 200 to ensure the drying effect on the clothes.

[0131] Please see Figures 2 to 4 In one optional embodiment, each air inlet branch duct 320, except for the air inlet branch duct 320 closest to the main air duct 310, is equipped with a second fan 420.

[0132] Specifically, a second fan 420 may also be installed in the air inlet branch duct 320 closest to the main air duct 310, and this application does not impose any restrictions on this.

[0133] Specifically, the air inlet branch duct 320 closest to the main air duct 310 does not have a second fan 420. Since the air pressure loss when flowing from the main air duct 310 to the nearest air inlet branch duct 320 is small, even without a second fan 420 in this air inlet branch duct 320, the drum 200 corresponding to this air inlet branch duct 320 can still have a large drying air volume, thereby achieving the goal of saving manufacturing costs for the garment processing equipment. Of course, none of the air inlet branch ducts 320 may have a second fan 420; this application does not impose this limitation.

[0134] Please see Figures 2 to 4 In one optional embodiment, the housing 100 further includes:

[0135] The third fan 430 is located in the air outlet connecting duct 350, and the third fan 430 is located between the two air outlet branch ducts 330 that are closest to the main duct 310.

[0136] Specifically, only some of the air outlet branch ducts 330 may be equipped with a third fan 430, or all of the air outlet branch ducts 330 may be equipped with a third fan 430, or none of the air outlet branch ducts 330 may be equipped with a third fan 430.

[0137] Specifically, the air outlet connecting duct 350 is equipped with a third fan 430. Turning on the third fan 430 allows hot and humid air to be quickly discharged from the drum 200 and enter the air outlet branch duct 330, thereby improving air circulation efficiency and enhancing the drying effect on the clothes inside the corresponding drum 200. Of course, each air outlet branch duct 330 may not be equipped with a third fan 430, and this application does not impose any restrictions on this.

[0138] Long-distance transport of drying air can cause a drop in air temperature, affecting the drying effect. Please refer to [link / reference needed]. Figure 4 In one alternative embodiment, the number of compressors 510 is one, and the heat pump system 500 further includes:

[0139] The second condenser 540 is disposed in the air inlet connecting duct 340, and the second condenser 540 is located between the two air inlet branch ducts 320 closest to the main duct 310. In some embodiments, the first condenser 520 and the second condenser 540 may each be equipped with a compressor 510.

[0140] In this embodiment, the second condenser 540 is located in the air inlet connecting duct 340 and between the two air inlet branch ducts 320 closest to the main duct 310. When the drying air heated by the first condenser 520 passes through the second condenser 540, it will be reheated to increase the air temperature. In this way, even if the drying air is transported over a long distance, the drying air can be kept at a high temperature, thereby improving the drying effect on clothes.

[0141] Furthermore, in this embodiment, the first condenser 520 and the second condenser 540 share the same compressor 510. Compared with the embodiment in which each condenser 520 and the second condenser 540 is equipped with a separate compressor 510, this embodiment can reduce the number of compressors 510, thereby reducing the cost of the clothing processing equipment, saving space inside the housing 100, and reducing the weight and volume of the clothing processing equipment.

[0142] In some embodiments, the first fan 410 may be located upstream of the evaporator 530 or downstream of the first condenser 520.

[0143] Please see Figures 2 to 4 In one alternative embodiment, the first fan 410 is located between the first condenser 520 and the evaporator 530.

[0144] Specifically, the first fan 410 is located upstream of the first condenser 520 and downstream of the evaporator 530. The first fan 410 draws air from the side of the evaporator 530. The first fan 410 can continuously draw air through the cold evaporator 530, thereby quickly removing the condensed moisture and preventing the evaporator 530 from frosting due to low temperature, thus ensuring continuous and efficient heat exchange.

[0145] Furthermore, the first fan 410 blows air toward the first condenser 520. Compared to the first fan 410 being located upstream of the evaporator 530, this embodiment allows the heated air to penetrate the clothes at higher pressure and flow rate, resulting in a more uniform airflow distribution, more thorough heat exchange, and ensuring a better drying effect.

[0146] In an optional embodiment, the housing 100 further includes:

[0147] The filter 910 is located at the inlet of the air outlet branch duct 330. This can filter impurities such as fibers from clothing, preventing impurities from clogging the first fan 410 and reducing air volume and drying effect.

[0148] Please see Figure 1 In one alternative embodiment, the housing 100 includes:

[0149] The front panel has a first garment inlet, a second garment inlet, and a third garment inlet. Specifically, the garment handling equipment also includes a first door 920, a second door 930, and a third door 940. The first door 920 is rotatably connected to the housing 100 to cover the first garment inlet, the second door 930 is rotatably connected to the housing 100 to cover the second garment inlet, and the third door 940 is rotatably connected to the housing 100 to cover the third garment inlet. The front panel of the housing 100 also has an inspection port with a drain pump cover 950. Opening the drain pump cover 950 allows for inspection and maintenance of the drain pump inside the housing 100.

[0150] The multiple rollers 200 include a first roller 210, a second roller 220 and a third roller 230. The opening of the first roller 210 is opposite to the first garment inlet, the opening of the second roller 220 is opposite to the second garment inlet, and the opening of the third roller 230 is opposite to the third garment inlet. The front panel is a one-piece structure.

[0151] In this embodiment, the garment processing equipment includes a large first drum 210, two smaller second drums 220 and a third drum 230. The second drums 220 and the third drum 230 are arranged side by side with a gap along the width direction of the housing 100. The first drum 210, the second drum 220 and the third drum 230 can all operate independently, thereby realizing zoned washing. Zoned washing can separate garments with different washing requirements for washing. For example, underwear and other intimate clothing can be washed separately from outerwear, socks and other clothing to avoid cross-contamination and ensure the washing quality of the garments.

[0152] Please see Figure 5 This application also provides a garment processing device, including:

[0153] Box 100, the box 100 contains:

[0154] Multiple spaced outer cylinders 700.

[0155] Specifically, the outer cylinder 700 can be installed inside the housing 100 via a suspension spring, and the outer cylinder 700 is used to hold washing water.

[0156] Multiple rollers 200 are rotatably disposed within each outer cylinder 700. Each roller 200 has a receiving cavity 201 formed within it for accommodating clothing and for tumbling the clothing within the roller 200. The multiple rollers 200 include:

[0157] First roller 210.

[0158] The second roller 220 is positioned higher than the first roller 210, and the diameter of the second roller 220 is smaller than the diameter of the first roller 210.

[0159] Specifically, the number of second rollers 220 can be one or two. When there are two second rollers 220, the two second rollers 200 are distributed at intervals along the width direction of the box 100.

[0160] Multiple independent drying air ducts 300 are respectively located outside each drum 200. The inlet and outlet of the drying air duct 300 are connected to the receiving cavity 201 of the drum 200 to form a circulation loop.

[0161] Multiple air supply fans 440 are respectively installed in each drying air duct 300, so that air circulates between the drying air duct 300 and the accommodating cavity 201.

[0162] Heat pump system 500, including:

[0163] Compressor 510 is used to compress refrigerant.

[0164] The first condenser 520 is located in the drying air duct 300 corresponding to the first drum 210, and is used to liquefy the refrigerant in the heat pump system 500.

[0165] Evaporator 530 is located in drying air duct 300 corresponding to the first drum 210. Along the air direction in the drying air duct 300, the first condenser 520 is located downstream of evaporator 530. Evaporator 530 is connected in series with compressor 510 and first condenser 520.

[0166] Specifically, the heat pump system 500 may also include an expansion valve 550, which is connected in series between the condenser and the evaporator 530. The expansion valve 550 is used to regulate the flow rate of the refrigerant to reduce the pressure of the refrigerant and change the boiling point of the refrigerant. The evaporator 530 here has a fluid passage for introducing the refrigerant, which is connected in series with the condenser and the compressor 510.

[0167] Specifically, the heat pump system 500 may also include an expansion valve 550, which is connected in series between the condenser and the evaporator 530. The expansion valve 550 is used to regulate the flow rate of the refrigerant to reduce the pressure of the refrigerant and change the boiling point of the refrigerant. The evaporator 530 here has a fluid passage for introducing the refrigerant, which is connected in series with the condenser and the compressor 510.

[0168] Specifically, after the refrigerant is discharged from the refrigerant outlet of the compressor 510, it can enter the refrigerant inlet of the condenser through the refrigerant pipeline, and then enter the condenser. In the condenser, it releases heat, allowing it to heat the surrounding air. The air, heated by the condenser, then enters the containment chamber 201, where it can dry clothes. Afterward, the refrigerant is discharged from the refrigerant outlet of the condenser and enters the expansion valve 550. Under the action of the expansion valve 550, the refrigerant pressure is reduced, and then it enters the refrigerant inlet of the evaporator 530. In the evaporator 530, the refrigerant absorbs heat, allowing the evaporator 530 to cool the surrounding air. The humid, hot air discharged from the containment chamber 201 cools down under the action of the evaporator 530, causing moisture to precipitate and form water droplets. A drainage structure can be installed at a corresponding position on the evaporator 530 to collect and discharge the water droplets. Finally, the refrigerant is discharged from the refrigerant outlet of the evaporator 530 and re-enters the compressor 510 from the refrigerant inlet.

[0169] Multiple electric heaters 600 are installed in each drying air duct 300.

[0170] Specifically, each electric heater 600 is used to heat the air within each drying duct 300 to form drying air.

[0171] A straight exhaust pipe is connected to an outer cylinder 700 that is sleeved outside the second roller 220, so as to exhaust the hot and humid air inside the outer cylinder 700.

[0172] In this embodiment, the first drum 210, with its larger diameter, holds more clothes and generates a larger flow of humid air during drying. Therefore, the evaporator 530 is used to condense the humid air, and the condensed dry air is reheated and then fed back into the first drum 210. This avoids directly venting large amounts of humid air into the customer's home, preventing a damp environment that could harm the customer's health or damage their furniture. Conversely, the second drum 220, with its smaller diameter, holds fewer clothes and generates a smaller flow of humid air during drying. Therefore, even if the humid air were discharged into the customer's home through a direct exhaust pipe, the impact on the customer would be negligible. This reduces the manufacturing cost and size of the clothing processing equipment.

[0173] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
