Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a clothing processing device. Background Art

[0002] In the prior art, most clothing processing devices (especially washing and drying machines) use electric heating to dry clothes. Electric heating clothing processing devices (especially washing and drying machines) adopt the principle of internal circulation. The fan blows out air flow, and after the air flow passes through the special-shaped heating tube in the drying duct and is heated to a certain temperature, the hot air flow passes through the drying duct into the washing drum, taking away the water vapor in the clothes in the inner drum to dry the clothes. The hot and humid water vapor enters the condensation duct of the rear drum, and then condensed water is passed into the condensation duct to reduce the temperature and humidity of the hot and humid water vapor. The low-humidity water vapor enters the drying duct again and is heated again into high-temperature and low-humidity steam to enter the drum to dry the clothes. The drying duct components play an important role in the whole process. At present, most drying ducts basically use a single special-shaped heating tube for heating, which cannot provide clothing care for fabrics of different materials. At the end of drying, the clothes will have a lot of wrinkles.

[0003] In summary, clothes dried by clothes processing devices in the prior art may have a lot of wrinkles. Summary of the Invention

[0004] An embodiment of the present invention provides a clothes processing device to solve the problem that clothes dried by clothes processing devices in the prior art have a large number of wrinkles.

[0005] To achieve the above-mentioned objectives, the present invention provides a clothing processing device, comprising: an air duct shell, the air duct shell having a drying air duct; a heating structure, the heating structure being connected to the air duct shell and located in the drying air duct; a spray device, the spray device being arranged on the air duct shell, the spray device being arranged at the drying air duct, and the spray device being used to spray water into the drying air duct.

[0006] Furthermore, the spray device is arranged corresponding to the heating structure, and the spray direction of the spray device is toward the heating structure.

[0007] Furthermore, the spraying device includes a nozzle and a water pipe that are connected to each other. The nozzle is located in the drying air duct, and the water pipe passes through the air duct shell and is connected to and communicates with the nozzle.

[0008] Furthermore, the first end of the nozzle is connected to the water pipe, and the second end of the nozzle is provided with multiple nozzles, which are connected to the water pipe through the internal water channel of the nozzle, and the inner diameter of the internal water channel gradually decreases from the first end to the second end of the nozzle.

[0009] Furthermore, there are multiple heating structures, which include at least a first heating structure and a second heating structure. The first heating structure and the second heating structure can generate heat independently, and the power of the first heating structure is greater than that of the second heating structure.

[0010] Furthermore, the heating structure includes: a disc-shaped shell, which is buckled on the inner wall of the drying air duct, and the disc-shaped shell has an upper surface parallel to the air flow direction of the drying air duct.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0027] See also Figures 1 to 8 As shown, according to an embodiment of the present invention, a clothing processing device is provided (this embodiment takes a washing and drying machine as an example), the clothing processing device includes an air duct shell 10, a heating structure 20 and a spray device 30, the air duct shell 10 has a drying air duct 11; the heating structure 20 is connected to the air duct shell 10 and is located in the drying air duct 11; the spray device 30 is arranged on the air duct shell 10, and the spray device 30 is arranged at the drying air duct 11, and the spray device 30 is used to spray water into the drying air duct 11.

[0028] The laundry treatment device of the present invention offers a novel structure. A heating structure is installed within the drying duct, heating the airflow to a high temperature. Furthermore, a spraying device is located within the drying duct. After the clothes are dried, the device enters the clothing care phase. The spraying device and the heating structure work together, and the water droplets sprayed by the spraying device encounter the heat generated by the heating structure, vaporizing them into high-temperature steam that enters the inner drum of the laundry treatment device. This high-temperature steam effectively cares for fabrics and reduces wrinkles. Furthermore, integrating the drying and care functions into the same device significantly saves space within the laundry treatment device.

[0029] Preferably, the spray device 30 is provided in correspondence with the heating structure 20, and the spraying direction of the spray device 30 is toward the heating structure 20. The installation position of the spray device 30 corresponds to the heating structure 20, that is, they are both located at the same stage position in the drying air duct 11 (sufficiently so that the water droplets sprayed by the spray device 30 can be evaporated by the heating structure 20 to form water vapor); and in terms of quantity, if there are multiple heating structures 20, then multiple spray devices 30 are also provided accordingly, preferably with a one-to-one correspondence between the spray device 30 and the heating structure 20. The spraying direction of the spray device 30 is directly toward the heating structure 20, which can enable the water droplets to form water vapor more quickly.

[0030] See also Figure 2 and Figure 4 The spray device 30 includes a nozzle 31 and a water pipe 32. The nozzle 31 is located in the drying air duct 11. The water pipe 32 passes through the air duct housing 10 and is connected to and communicates with the nozzle 31. The water pipe 32 can be directly plugged into or clipped onto the nozzle 31. There are many ways to connect the nozzle 31 and the water pipe 32.

[0031] The first end of the nozzle 31 is connected to the water pipe 32, and the second end of the nozzle 31 is provided with multiple nozzles 33. The nozzles 33 are connected to the water pipe 32 through an internal waterway of the nozzle 31. The inner diameter of the internal waterway gradually decreases from the first end to the second end of the nozzle 31. The nozzles are tapered internally, narrowing at the nozzles 33. Based on the Venturi principle, the internal diameter of the pipe decreases, thereby increasing the flow rate of the water. This increases the flow rate and the spray range. Compared with a single water stream, the nozzle of this embodiment has a wider spray range, and the sprayed water droplets are more likely to form water vapor.

[0032] The drying air duct of the washing and drying machine in the prior art generally has only one electric heating tube, which cannot protect and care for clothes by adjusting the temperature. When drying high-end fabrics, high temperature may damage the clothes. In order to solve the above-mentioned problems of the prior art, further improvements have been made in the washing and drying machine of this embodiment. The washing and drying machine has multiple heating structures 20, and the multiple heating structures 20 include at least a first heating structure and a second heating structure. The first heating structure and the second heating structure can generate heat independently, and the power of the first heating structure is greater than the power of the second heating structure. The clothing processing device of the present invention is provided with at least two heating structures of different powers, the power of the first heating structure is larger, and the power of the second heating structure is smaller; combined with Figure 1 and Figure 3 As shown, the clothes processing device is provided with two heating structures of different sizes. In this embodiment, the first heating structure is a heating structure of larger size, located at Figure 1 The second heating structure in this embodiment is a heating structure of smaller volume, located Figure 1Because the first and second heating structures generate heat independently, they can operate simultaneously to achieve the maximum power of the drying duct. Of course, more than three heating structures can be set, but at least two heating structures must have different power levels and operate independently. The heating structures can also be set in groups, with each group set to operate in the same manner.

[0033] Based on the above structural foundation, the clothing processing device of this embodiment can select different heating structures according to different clothing materials, or all heating structures can work together to reduce damage to clothing caused by high drying temperatures. For example, when the user selects the mode for washing wool, silk, down, etc., these high-end fabrics will be damaged by higher drying temperatures. In this case, the lower-power heating structure can be controlled to work alone, and warm air drying can protect the fabric.

[0034] Not only that, the number and operation mode of the heating structures can also be selected according to the weight of the clothes, moisture content, etc., to further improve the intelligent operation of the clothing processing device. For example: in the drying mode, when the moisture content is greater than X%, it means that the clothes are relatively wet. The main control board of the clothing processing device controls all the heating structures to work simultaneously, that is, the strong drying mode. The higher wind temperature can quickly dry the clothes in a short time, shortening the drying time. In the care mode, when the weight of the clothes is greater than A (kg) and less than B (kg), the quality of the clothes is moderate, and the heating structure with lower power is turned off, and the heating structure with higher power is controlled to provide heat. When the weight of the clothes is less than A (kg), the quality of the clothes is relatively light. In order to save energy efficiency, only the heating structure with lower power is turned on to provide heat.

[0035] See also Figure 3 and Figure 5 The heating structure 20 includes a disc-shaped housing 21, which is fastened to the inner wall of the drying duct 11 and fixed to the duct housing via screws. The disc-shaped housing 21 has an upper surface 211 that is parallel to the airflow direction of the drying duct 11. The shape, structure, and upper surface 211 of the disc-shaped housing 21 are designed to reduce obstruction to airflow and minimize air volume loss. Furthermore, compared to conventional irregularly shaped heating tubes, the disc-shaped housing 21 has no dead corners, effectively preventing lint from accumulating in these dead corners. This solves the problem of lint clinging to irregularly shaped heating tubes in conventional technology, which can burn and cause a burnt odor on clothes after drying.

[0036] Preferably, the disc-shaped housing 21 further has a smooth curved surface 212 connected to the upper surface 211. In this embodiment, the smooth curved surface 212 is an annular curved surface, meaning that the disc-shaped housing 21 is disc-shaped overall. The smooth curved surface 212 further reduces airflow obstruction. The surface of the disc-shaped housing 21 is made of stainless steel, primarily to prevent sprayed water droplets from adhering to the outer surface and forming rust spots.

[0037] The disc-shaped housing 21 forms a mounting space with the inner wall of the drying duct 11. The heating structure 20's electric heating tube 22 and temperature limiter 23 are both located within this mounting space. The heating tube 22 provides heat when powered, while the temperature limiter 23 prevents the electric heating from overheating, creating a safety hazard.

[0038] Combine Figure 1 and Figure 2 As shown, the air duct housing 10 includes a detachably connected air duct upper cover 12 and an air duct lower cover 13, which are buckled together to form the drying air duct 11. The air duct upper cover 12 can be directly removed for easy cleaning and maintenance.

[0039] Combine Figures 6 to 8 As shown, the duct upper cover 12 is provided with a first groove 41, and the duct lower cover 13 is provided with a second groove 42. When the duct upper cover 12 and the duct lower cover 13 are fastened together, the first groove 41 and the second groove 42 are fastened together to form a mounting hole 40 for mounting the spray device 30. The spray device 30 is inserted into the mounting hole 40, and the mounting hole and the spray device are fixed by an interference fit using a rubber ring around the outer periphery of the spray device.

[0040] In order to further facilitate installation and maintenance, there are multiple heating structures 20, some of which are installed on the air duct upper cover 12, and some of which are installed on the air duct lower cover 13.

[0041] In consideration of the smoothness of air flow and the reduction of wind resistance, the multiple heating structures 20 are staggered and arranged in sequence along the air flow direction of the drying air duct 11 .
