[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] The inventors discovered that in related technologies, steam generators mainly fall into two categories: one is a device that heats water with an electric heater to produce steam, and the other is a device that sprays water droplets (mostly in a mist) onto clothing or the surrounding air without heating water. Compared to steam generators that generate steam through electric heating, steam generators using water droplets are cheaper and safer, but their effectiveness in reducing wrinkles and removing odors is significantly reduced. Furthermore, while steam generators using water droplets perform well in reducing wrinkles and removing odors, they are more expensive, less safe (especially when using flammable refrigerant gases), and require more complex control boards to handle additional switches, temperature sensors, and water level sensors. These devices must ensure a minimum amount of water is present inside the steam generator before the electric heater is activated. Additionally, since clothing processing equipment sometimes requires refrigerant, the maximum temperature of the steam generator must not exceed the minimum auto-ignition temperature of the increasingly common flammable refrigerant gases in Europe. Based on the above, this application provides a garment processing device that improves the structure of the garment processing device for generating steam.

[0041] like Figure 1 The diagram shown is a schematic diagram of the structure of a clothing processing device 10 according to an embodiment of this application. The clothing processing device 10 includes a roller 100, which has a clothing processing chamber 101 inside. The roller 100 also has a loading port that communicates with the clothing processing chamber 101. Clothes can be loaded into the clothing processing chamber 101 through the loading port or taken out of the clothing processing chamber 101 through the loading port.

[0042] The garment processing equipment 10 also includes a heat pump system 200, such as Figure 2 The diagram shown is a schematic representation of a heat pump system 200 according to an embodiment of this application. (In conjunction with...) Figure 1 and Figure 2The heat pump system 200 includes a medium circuit 201 with a heat exchange medium, and a compressor 210, a condenser 230, a pressure reducing device 240 and an evaporator 220 disposed on the medium circuit 201. The clothing handling device 10 also includes a steam generator 250, which contains water. The steam generator 250 is disposed on the medium circuit 201 and exchanges heat with the heat exchange medium to generate steam. The steam generator 250 is connected to the clothing handling chamber 101 to deliver steam to the clothing handling chamber 101.

[0043] In this embodiment, the heat exchange medium in the heat pump system 200 can exist in various forms such as high-pressure gaseous refrigerant, low-pressure gaseous refrigerant, low-pressure gas-liquid refrigerant, and high-pressure liquid refrigerant. Specifically, the working principle of the heat pump system 200 is as follows: the compressor 210 draws in low-pressure gaseous refrigerant, which is then compressed by the compressor 210 and discharged as high-pressure gaseous refrigerant. It then continues to enter the condenser 230, where the high-pressure gaseous refrigerant exchanges heat with the air around the condenser 230 to heat the air around the condenser 230. The high-pressure gaseous refrigerant condenses into high-pressure liquid refrigerant. After the high-pressure liquid refrigerant flows through the pressure reducing device 240 for throttling and pressure reduction, it becomes a low-pressure gaseous-liquid two-phase mixture and enters the evaporator 220. The low-pressure gaseous-liquid refrigerant exchanges heat with the air around the evaporator 220, absorbing heat from the air around the evaporator 220 to cool the air around the evaporator 220. The low-pressure gaseous-liquid refrigerant forms low-pressure gaseous refrigerant, which re-enters the compressor 210 and is pressurized by the compressor 210 to form high-pressure gaseous refrigerant. This cycle repeats continuously, achieving heat exchange.

[0044] The working process of the garment processing equipment 10 is as follows: The condenser 230 heats the circulating air in its space (i.e., the circulating air duct 310 mentioned below), generating dry air at approximately 40℃-65℃, which is then transported to the garment processing chamber 101. In the garment processing chamber 101, the dry air flows over the surface of the wet garments, exchanges heat and moisture with the wet garments, absorbs the moisture from the garments, and becomes high-temperature, high-humidity gas, which is then discharged from the garment processing chamber 101. Figure 2 and Figure 3 The direction indicated by the dashed arrow is the direction in which the high-temperature and high-humidity gas passes through the evaporator 220 and the condenser 230. The high-temperature and high-humidity gas first passes through the evaporator 220, where it is cooled into low-temperature and low-humidity gas. Then it passes through the condenser 230, where it is heated into high-temperature and dry gas, and enters the next cycle. This cycle continues, achieving continuous and efficient drying of clothing.

[0045] In this embodiment, the steam generator 250 can be installed on the medium circuit 201 between any two of the compressor 210, condenser 230, pressure reducing device 240, and evaporator 220. The heat exchange medium in the medium circuit 201 can exchange heat with the water in the steam generator 250. The water absorbs heat and converts into steam. The heated steam acts on the clothes in the clothes processing chamber 101, which can remove wrinkles and odors from the clothes or wash the clothes. There is no need to set up other heating structures to heat the water into steam and then deliver it to the clothes processing chamber 101. Even when there is a lack of water in the steam generator 250, the temperature inside the steam generator 250 will not be out of control like an electric heater, but will reach a stable state similar to the outlet temperature of the compressor 210. There is no need to set up devices such as switches, temperature sensors, and water level sensors to monitor whether the steam generation is safe, thus saving costs. In addition, there is no need to activate the generation of water vapor through relays or other electromechanical devices, because if there is water in the steam generator 250, the high-pressure gaseous refrigerant will exchange heat with the water and generate water vapor. If there is no water in the steam generator 250, the high-pressure gaseous refrigerant will not exchange heat and will not generate water vapor. This not only saves costs but also simplifies the operation logic of the clothing processing equipment 10.

[0046] like Figure 2 As shown, the steam generator 250 is located downstream of the compressor 210 and upstream of the condenser 230. The compressor 210 receives low-pressure gaseous refrigerant from the evaporator 220. After being compressed by the compressor 210, the low-pressure gaseous refrigerant is discharged as high-pressure gaseous refrigerant. The steam generator 250 directly receives the high-pressure gaseous refrigerant from the compressor 210. The high-pressure gaseous refrigerant exchanges heat with the water inside the steam generator 250, turning the water into steam, which then continues to enter the condenser 230. In this position, the steam generator 250 can more efficiently receive the heat from the heat exchange medium output by the compressor 210, reducing heat loss, accelerating the steam generation rate, and producing higher-temperature steam.

[0047] In some embodiments, the compressor 210 is a variable frequency compressor. The temperature of the heat exchange medium output by the variable frequency compressor can be adjusted by adjusting the power of the variable frequency compressor. When the steam generator 250 is working, the temperature of the heat exchange medium discharged by the variable frequency compressor can be selected to be at a high point, thereby enabling the steam generator 250 to produce steam more efficiently.

[0048] The type of pressure reducing device 240 in this application embodiment is not limited and can be selected according to actual needs. For example, the pressure reducing device 240 is an expansion valve or a capillary tube.

[0049] The types of heat exchange media are not limited in the embodiments of this application, and can be selected according to actual usage requirements.

[0050] It is understandable that after the heat exchange medium enters the steam generator 250, it exchanges heat with the water in the steam generator 250, causing the heat contained in the steam generator 250 to gradually decrease. In some embodiments, the heat exchange medium in the medium circuit 201 flows counterclockwise with the water in the steam generator 250, enabling more efficient heat exchange between the heat exchange medium in the medium circuit 201 and the water in the steam generator 250. For example, the part of the medium circuit 201 used for heat exchange with the water in the steam generator 250 includes a front flow section, a middle flow section, and a rear flow section. The heat exchange medium in the medium circuit 201 flows sequentially along the front flow section, the middle flow section, and the rear flow section. The heat exchange medium exchanges heat with the water in the middle flow section and the rear flow section respectively, causing the water temperature to gradually increase. The heat exchange medium exchanges heat with the water in the front flow section, causing the water to vaporize and form steam, which enables more efficient heat exchange, thereby efficiently vaporizing water into steam.

[0051] like Figure 2 As shown, the steam generator 250 includes a water inlet 2521 and an air outlet 2522. Water enters the steam generator 250 through the water inlet 2521, and steam flows out of the steam generator 250 through the air outlet 2522. The medium circuit 201 includes a refrigerant inlet 2511 and a refrigerant outlet 2512. The heat exchange medium at the steam generator 250 flows from the refrigerant inlet 2511 to the refrigerant outlet 2512. In some embodiments, the water inlet 2521 of the steam generator 250 is located adjacent to the refrigerant outlet 2512 of the medium circuit 201, and the air outlet 2522 of the steam generator 250 is located adjacent to the refrigerant inlet 2511 of the medium circuit 201, thereby causing the heat exchange medium in the medium circuit 201 to flow counterclockwise to the water in the steam generator 250.

[0052] In some other embodiments, such as Figure 3 As shown, the water inlet 2521 of the steam generator 250 is located near the refrigerant inlet 2511 of the medium circuit 201, and the steam outlet 2522 of the steam generator 250 is located near the refrigerant outlet 2512 of the medium circuit 201, so that the heat exchange medium in the medium circuit 201 and the water in the steam generator 250 flow in the same direction, which can also meet the heat exchange requirements of converting water into steam.

[0053] The medium circuit 201 includes multiple medium pipelines. The compressor 210, condenser 230, pressure reducing device 240 and evaporator 220 are each connected by a corresponding medium pipeline. One medium pipeline has a refrigerant inlet 2511 and another medium pipeline has a refrigerant outlet 2512.

[0054] In some embodiments, the steam generator 250 includes a housing 251, with a receiving cavity inside the housing 251. A guide pipe 252 is provided inside the receiving cavity, and a guide channel is provided inside the guide pipe 252. One of the receiving cavity and the guide channel contains a heat exchange medium, and the other contains water, allowing the heat exchange medium and water to contact the guide pipe respectively, and heat exchange occurring through conduction via the guide pipe. The shape of the guide pipe 252 is not limited in this embodiment and can be selected according to actual needs. Specifically, when the guide pipe 252 contains a heat exchange medium and the receiving cavity contains water, the medium circuit 201 includes the guide pipe 252. One end of the guide pipe 252 is connected to a medium pipeline with a refrigerant inlet 2511, and the other end is connected to a medium pipeline with a refrigerant outlet 2512, allowing the guide pipe 252 to enter the receiving cavity. That is, in this case, a portion of the medium circuit 201 is located inside the receiving cavity. When the guide pipe 252 contains water and the containment cavity contains heat exchange medium, the steam generator 250 includes the guide pipe 252, and one end of the guide pipe 252 has a water inlet 2521 and the other end has an air outlet 2522. A medium pipeline with a refrigerant inlet 2511 and a medium pipeline with a refrigerant outlet 2512 are respectively installed on the shell 251 so that the refrigerant inlet 2511 and the refrigerant outlet 2512 are respectively connected to the containment cavity, thereby allowing the heat exchange medium to enter the containment cavity.

[0055] In some embodiments, the steam generator 250 is a plate heat exchanger, with a medium pipeline having a refrigerant inlet 2511 and a medium pipeline having a refrigerant outlet 2512 respectively installed on the plate heat exchanger so that the heat exchange medium can enter the interior of the plate heat exchanger.

[0056] In some embodiments, the steam generator 250 is a finned tube heat exchanger, and a medium pipeline with a refrigerant inlet 2511 and a medium pipeline with a refrigerant outlet 2512 are respectively installed in the finned tube heat exchanger so that the heat exchange medium can enter the interior of the finned tube heat exchanger.

[0057] The above is merely an exemplary description. The steam generator 250 of this application embodiment has a simple structure and is relatively easy to assemble and disassemble with other structural components. There is no need to design the structure of the steam generator 250 separately. Any device that enables the heat exchange medium to exchange heat with water is applicable to this application.

[0058] The steam generator 250's outlet 2522 is connected to the clothing processing chamber 101. Steam generated inside the steam generator 250 enters the clothing processing chamber 101 through the outlet 2522 to process the clothing. In some embodiments, the steam generator 250's inlet 2521 can be connected to an external water source to replenish water to the steam generator 250 in a timely manner. In some embodiments, the clothing processing device 10 further includes a water storage chamber. The steam generator 250's inlet 2521 is connected to the water storage chamber, which stores water. Water is supplied to the steam generator 250 through the water storage chamber. The water stored in the water storage chamber can be used to supply water to other channels of the clothing processing device 10, allowing the water inside the clothing processing device 10 to be recycled. For example, the housing 300 has a condensate collection chamber for collecting condensate inside the clothing processing device 10, forming a water storage chamber; or, the clothing... The garment processing device 10 includes a water storage box with a water storage chamber. The water storage box is detachably installed on the housing 300 of the garment processing device 10. When the water volume in the water storage chamber is low and cannot meet the water demand, the water storage box can be removed, water can be added to the water storage box, and then the water storage box can be installed on the housing 300. Alternatively, the garment processing device 10 has a housing 300 with a water storage chamber that is connected to the outside of the garment processing chamber 101. When the water volume in the water storage chamber is low and cannot meet the water demand, water can be directly added to the water storage chamber.

[0059] Please refer to the following: Figure 1 The housing 300 of the garment processing device 10 has a circulating air duct 310 inside, which is connected to the garment processing chamber 101. Gas in the circulating air duct 310 enters the garment processing chamber 101 to dehumidify the garments and then recirculates back into the circulating air duct 310, thus achieving internal airflow circulation. In some embodiments, the circulating air duct 310 includes a front exhaust channel 301, a heat exchange channel 302, and a rear intake channel 303 connected in sequence. An evaporator 220 and a condenser 230 are disposed within the heat exchange channel 302. The front exhaust channel 301 and the rear intake channel 303 are respectively connected to the garment processing chamber 101. Gas in the garment processing chamber 101 flows back into the garment processing chamber 101 sequentially through the front exhaust channel 301, the heat exchange channel 302, and the rear intake channel 303, thus circulating and forming a drying path to achieve continuous and efficient drying of the garments.

[0060] In some embodiments, the outlet 2522 of the steam generator 250 is connected to the rear air intake channel 303. The steam output from the steam generator 250 enters the rear air intake channel 303 and then enters the clothing processing chamber 101. Optionally, the steam output from the outlet 2522 of the steam generator 250 and the high-temperature drying gas enter the clothing processing chamber 101 at different times. For example, the high-temperature drying gas can be introduced into the clothing processing chamber 101 through the air intake channel to dry the clothes first, and then the steam can be introduced into the clothing processing chamber 101 through the air intake channel to process the clothes; or, the high-temperature drying gas and steam can be introduced into the clothing processing chamber 101 through the air intake channel to process the clothes simultaneously.

[0061] In some embodiments, such as Figure 4 As shown, the garment processing device 10 also includes a front support 320, which is disposed on the front side of the roller 100 and installed in the housing 300. The roller 100 is rotatably installed in the housing 300. The front support 320 has an airflow channel inside, which is connected to the air outlet 2522 of the steam generator 250 and the garment processing chamber 101, respectively, so that steam enters the garment processing chamber 101 from the airflow channel.

[0062] Optionally, the airflow channel is connected to the air outlet 2522 of the steam generator 250 through the front air outlet channel 301, or the airflow channel is connected to both the front air outlet channel 301 and the air outlet 2522 of the steam generator 250, so that the high-temperature drying gas and steam share the same front air outlet channel 301 to enter the clothing processing chamber 101.

[0063] Optionally, the front support 320 has multiple airflow channels inside. One part of the airflow channels is connected to the front air outlet channel 301 to guide high-temperature drying gas into the clothing processing chamber 101, and another part of the airflow channels is directly connected to the air outlet 2522 of the steam generator 250 to guide steam into the clothing processing chamber 101, so that the high-temperature drying gas and steam enter the clothing processing chamber 101 from different airflow channels.

[0064] like Figure 5As shown, the garment processing device 10 also includes a drive motor 610 and a fan 620. Both the drive motor 610 and the fan 620 are mounted on the housing 11. The space where the fan 620 is located is connected to the rear air intake channel 303. The drive motor 610 is connected to the fan 620 and is used to drive the fan 620 to rotate, thereby driving the airflow in the rear air intake channel 303 into the garment processing chamber 101. In some embodiments, the compressor 210, steam generator 250, condenser 230, pressure reducing device 240, and evaporator 220 are located below the drum 100. The compressor 210, steam generator 250, pressure reducing device 240, and drive motor 610 can be located outside the circulation duct 310 to prevent these devices from interfering with the airflow in the circulation duct 310.

[0065] The garment processing device 10 also includes a transmission assembly, which is connected to the drive motor 610 and the roller 100 respectively. When the drive motor 610 is running, it drives the roller 100 to rotate through the transmission assembly. This application embodiment does not limit the type of transmission assembly. Any transmission assembly that can be connected to the drive motor 610 and drive the roller 100 to rotate is applicable to this application. For example, the transmission assembly is a pulley transmission assembly.

[0066] In some embodiments, the garment processing device 10 further includes a valve body 400 and a water inlet pipe 500. The water inlet 2521 of the steam generator 250 is connected to the water inlet pipe 500 to receive water delivered by the water inlet pipe 500. The valve body 400 is installed on the water inlet pipe 500 to regulate the flow state of the water inside the water inlet pipe 500, thereby regulating the state of the steam output by the steam generator 250. Optionally, the flow rate of water supplied from the water inlet pipe 500 to the steam generator 250 can be adjusted by the valve body 400 to regulate the amount of steam output by the steam generator 250. Alternatively, the flow of water in the water inlet pipe 500 can be adjusted by the valve body 400. For example, when it is not necessary to supply steam to the clothes processing chamber 101, the valve body 400 can be controlled to cut off the water flow in the water inlet pipe 500 to stop water from being supplied to the steam generator 250. When it is necessary to supply steam to the clothes processing chamber 101, the valve body 400 can be controlled to open the water flow in the water inlet pipe 500 to supply water to the steam generator 250.

[0067] In some embodiments, the garment processing device 10 may include a plurality of rollers 100, and a steam generator 250 is connected to the garment processing chamber 101 of at least one roller 100. The rollers 100 are axially parallel, and the inlets of the rollers 100 all face the front of the garment processing device 10. When the steam generator 250 is connected to the garment processing chambers 101 of the rollers 100, the garment processing device 10 may also include a plurality of air guide pipes. Each air guide pipe is connected to a corresponding garment processing chamber 101 of the rollers 100, and all air guide pipes are connected to the steam generator 250. The garment processing device may have a plurality of switching valves, with each air guide pipe equipped with a switching valve. The switching valves are used to regulate the flow state of steam inside the air guide pipes, so as to deliver corresponding steam to the garment processing chamber 101 of the corresponding roller 100 according to the steam requirements of the rollers 100.
