[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] See also Figures 1 to 3, this embodiment provides a clothing care machine, which has a processing chamber, including a heater 100 and a fan assembly 200. The heater 100 includes a heater housing 110 and a PTC (Positive Temperature Coefficient) heating element arranged in the heater housing 110, the top of the heater housing 110 has an air outlet 1101, the air outlet 1101 is connected to the inside of the processing chamber, and the bottom of the heater housing 110 has a first connecting port 1102. The fan assembly 200 includes a fan housing 210 and a fan 220 arranged in the fan housing 210, the fan 220 is used to generate an airflow, and the air outlet end of the fan housing 210 is connected to the first connecting port 1102. The airflow generated by the fan 220 can enter the heater housing 110 through the first connecting port 1102, and flow out from the air outlet 1101 after flowing through the PTC heating element 120.

[0040] The heater 100 in the above-mentioned clothing care machine uses a PTC heating element 120 to heat the airflow blown out by the fan 220. Due to the advantages of low thermal resistance and high heat exchange efficiency, the airflow blown out by the fan 220 can be quickly heated up, and after entering the processing chamber through the air outlet 1101, a good drying effect is achieved. The PTC heating element 120 is arranged in the heater housing 110, and the fan 220 is arranged in the fan housing 210, and the first connecting port 1102 of the heater housing 110 is connected to the air outlet end of the fan housing 210. The heater housing 110 and the fan housing 210 can guide the airflow to ensure that the hot air can flow to the processing chamber to avoid heat loss.

[0041] Furthermore, the clothes processing device in this embodiment includes a box body 10, a partition 20 is arranged in the box body 10, the processing chamber is above the partition 20, and the heater 100 and the fan assembly 200 are placed below. Two vents are arranged on the partition 20, one vent is connected to the air inlet, and the other vent is connected to the return air port 4101.

[0042] Further, see Figures 4 to 6 A heat dissipation fan 600 is provided on the side of the condenser 300, and the heat dissipation fan 600 is used to dissipate heat from the condenser 300. In this embodiment, two heat dissipation fans 600 are provided, and in other embodiments, the number of the heat dissipation fans 600 is set according to the use requirements.

[0043] The cooling fan 600 is used to dissipate heat from the condenser 300. Within a certain temperature range, the cooling fan 600 does not start. When the temperature of the condenser 300 is too high, the cooling fan 600 starts to suck air from the condenser 300 to take away excess heat to prevent danger. Optionally, a fan cover 440 is provided on the cooling fan 600.

[0044] Furthermore, the clothing care machine is provided with an external circulation inlet 11 and an external circulation outlet 12. The cooling fan 600 draws in external airflow from the external circulation inlet 11. After the external airflow passes through the condenser 300, it flows out from the external circulation outlet 12, thereby forming an air duct for the cooling airflow.

[0045] Further, see Figure 7 The clothing care machine further includes a guide member 400, which includes a guide channel 410. The guide channel 410 has a return air port 4101 and a second connecting port, the return air port 4101 is connected to the inside of the treatment chamber, and a condenser 300 is arranged between the second connecting port and the air inlet section of the fan housing 210.

[0046] By providing the guide channel 410, the airflow blown into the treatment chamber by the fan 220 can enter the guide channel 410 through the return air port 4101, and flow to the condenser 300 through the second connecting port, and after heat exchange with the condenser 300, enter the fan housing 210, thereby forming an internal circulation in the clothing care machine. The heat exchange between the condenser 300 and the airflow can dry the airflow, thereby reducing the humidity in the treatment chamber and quickly drying the clothes.

[0047] Furthermore, a filter plate 500 is provided at the return air outlet 4101 of the guide channel 410. The filter plate 500 can block the lint from the clothes and prevent the lint in the treatment room from entering the guide channel 410 and then being sucked into the fan 220, entangled with the fan 220, affecting the service life of the fan 220, or being heated by the condenser 300, causing danger.

[0048] Further, the guide member 400 further includes a cover plate 420, the guide channel 410 is connected to one end of the cover plate 420, the fan assembly 200 and the heater 100 are arranged at the other end of the cover plate 420, and the cover plate 420 is arranged above the condenser 300. The cover plate 420 has a shielding function to prevent the heat dissipation of the condenser 300. In this embodiment, the fan cover 440 is connected to the cover plate 420 and is integrally formed with the cover plate 420.

[0049] Furthermore, reinforcing ribs may be provided on the top of the cover plate 420. Since the cover plate 420 is relatively thin and has a relatively large area, providing the reinforcing ribs may increase the structural strength of the cover plate 420 and reduce deformation.

[0050] In this embodiment, the reinforcing ribs are strip-shaped, including transverse reinforcing ribs and longitudinal reinforcing ribs, and the transverse reinforcing ribs and longitudinal reinforcing ribs are arranged vertically. Optionally, multiple transverse reinforcing ribs and longitudinal reinforcing ribs are provided, and multiple transverse reinforcing ribs are arranged at equal intervals, and multiple longitudinal reinforcing ribs are arranged at equal intervals.

[0051] Furthermore, a guide cover 430 is provided at one end of the cover plate 420 away from the guide channel 410. The air outlet end of the guide cover 430 is connected to the fan housing 210, which can guide the airflow and guide the airflow into the fan housing 210, so that the airflow circulation efficiency is high.

[0052] Furthermore, at least a portion of the heater housing 110 is placed above the air deflector 430 , that is, a portion of the structure of the heater 100 is located above the air deflector 430 , and the layout of the components is reasonable, so that the overall structure is compact.

[0053] Further, see Figure 8 The heater housing 110 includes a front cover 111 and a rear cover 112, the first communication port 1102 is arranged at the bottom of the front cover 111, and the bottom of the rear cover 112 is placed on the air guide cover 430. Optionally, the front cover 111 and the rear cover 112 are connected by bolts. By setting the heater housing 110 as a split type, the PTC heating element 120 can be easily installed. In other embodiments, the heater housing 110 can be an integrated structure.

[0054] Optionally, the air outlet end of the air deflector 430 is tilted downward, and the bottom of the rear cover 112 is arranged to fit the air deflector 430 to ensure that the structures of the two are stable. Optionally, the front cover 111 and the rear cover 112 can be connected by bolts, and the assembly is reliable and the connection is stable.

[0055] Further, see Fig. 9 The bottom of the cover plate 420 is provided with a flow-blocking rib 421, which extends along the flow direction of the airflow. The flow-blocking rib 421 can block the airflow above the condenser 300, so that the airflow is sucked out from the gap in the width direction of the condenser 300, thereby improving the heat dissipation efficiency. Optionally, a plurality of flow-blocking ribs 421 are provided, and the plurality of flow-blocking ribs 421 are arranged at equal intervals.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
