[0002] With the development of society, the popularity of dryers is increasing. It can not only dry wet clothes in a short time, but also disinfect and sterilize clothes. Especially in rainy weather, it is difficult for clothes to dry. Dryers can solve the problem that clothes are not easy to dry on rainy days. The temperature can be maintained at around 70 degrees during operation, which can make life more efficient and convenient.
[0003] In the drum type clothes treatment device, the heat pump drying and condensation drying methods are to heat the clothes to evaporate water, and then condense the condensed water to complete the drying of the clothes. The condensed water is discharged through the drain pipe.
[0004] In the related art, there are two ways to drain condensed water: one is to drain it directly into the outer drum and then drain it through a drainage pump, and the other is to connect it directly to the drainage pipe and drain it through the drainage pump. The method of draining it directly into the outer drum has a simple structure, but there is a problem that the water vapor in the outer drum enters the drying duct through the drainage pipe. When drying, the temperature in the drum is high and the condensed water cannot be drained smoothly under the pressure, resulting in a decrease in the efficiency of evaporator water precipitation, affecting the drying performance; the second solution has a complex structure and a long fixed pipeline, which affects the assembly efficiency and cost.

[0080] A condensation chamber 310 is formed in the drying air duct 300 , and an inlet 311 and an outlet 312 are provided on the drying air duct 300 . The inlet 311 and the outlet 312 are connected to the condensation chamber 310 respectively.
[0081] One end of the drying air duct 300 is connected to the air inlet 220 of the barrel 200, and the other end of the drying air duct 300 is connected to the air outlet 230 of the barrel 200. Specifically, the inlet 311 of the drying air duct 300 is connected to the air outlet 230 of the barrel 200, and the outlet 312 of the drying air duct 300 is connected to the air inlet 220 of the barrel 200. When the barrel 200 is drying, one side of the gas in the barrel 200 passes through the air outlet 230, the condenser 420, and the air inlet 220, and returns to the barrel 200, so that the gas circulates between the barrel 200 and the drying air duct 300.
[0082] The drying air duct 300 includes an air guide member 320 and a cover plate (not shown) covering the upper portion of the air guide member 320 .
[0083] The air guide 320 includes a bottom plate 321 and a surrounding plate 322. The surrounding plate 322 protrudes from the upper surface of the bottom plate 321 and encloses to form an annular structure. The surrounding plate 322 and the surrounding plate 322 enclose a condensing chamber 310 with an open top, and the cover plate is detachably covered on the upper end of the surrounding plate 322, and the cover plate is sealed and attached to the surrounding plate 322.
[0084] A downwardly protruding drainage portion 330 is formed at the lower end of the drying air duct 300 . A drainage port that passes through from top to bottom is formed on the drainage portion 330 to discharge condensed water in the drying air duct 300 .
[0085] In this embodiment, a water collecting trough is formed in the drying air duct 300, and the water collecting trough is opened on the ground of the condensation tank, and the water collecting trough is used to collect condensed water in the condensation chamber 310. The drainage portion 330 is opened at the water collecting trough. In the direction close to the drainage portion 330, the bottom wall of the water collecting trough is inclined downward.
[0086] Figure 8 It is a schematic diagram of the position of the drying component 400 of the present invention.
[0087] See also Figures 2 to 8 The clothes processing device further includes a drying component 400, which is disposed in the drying air duct 300; the drying component 400 is used to introduce the gas in the drum 200 into the drying air duct 300 for condensation and heating, and then discharge it into the drum 200. The drying component 400 is used to dehumidify and heat the gas in the accommodating chamber 210 to form hot air.
[0088] In this embodiment, the drying component 400 is a heat pump drying system, and the drying component 400 includes an evaporator 410 and a condenser 420. The evaporator 410 and the condenser 420 are both disposed in the drying air duct 300, and the evaporator 410 and the condenser 420 are sequentially arranged along the air guide direction of the drying air duct 300. Among them, the evaporator 410 is used to condense the moisture in the gas introduced from the air outlet 230 into the condensation chamber 310, and the condenser 420 is used to heat the gas after condensation by the evaporator 410, and introduce the heated gas into the accommodating chamber 210, so as to dry the clothes in the accommodating chamber 210.
[0089] The drying assembly 400 further includes a compressor 430. The compressor 430, the condenser 420, and the evaporator 410 are connected in sequence. A refrigerant flows in the compressor 430, so that the refrigerant absorbs heat at the evaporator 410 to condense the moisture in the air outside the evaporator 410 to obtain condensed water. The refrigerant dissipates heat at the condenser 420, thereby heating the gas outside the condenser 420.
[0090] The evaporator 410 and the condenser 420 are both disposed in the drying air duct 300 . The evaporator 410 is used to condense moisture in the gas discharged from the air outlet 230 , and the condenser 420 is used to heat the gas to be introduced into the accommodating chamber 210 .
[0091] In this embodiment, the compressor 430 is fixed on the bottom of the housing 100. In some embodiments, the compressor 430 is fixed on other positions on the housing 100.
[0092] It should be noted that, in some embodiments, the drying component 400 is a condensation drying system. The structure of the condensation drying system refers to the structure of the condensation drying system in the related art, which will not be described in detail here.
[0093] It should be understood that the clothing processing device provided in the present application may be a clothes dryer, which is only used to dry the clothes. The clothing processing device may also be a washing and drying machine, in which case the clothes can be washed and dried, the clothes can be dried after being washed, or the clothes can be washed or dried only. Since the system for realizing the drying function of the clothing processing device is the drying component 400, the clothing processing device is a heat pump clothes dryer or a heat pump washing and drying machine.
[0094] The drying assembly 400 further includes a fan (not shown in the figure), which is used to drive the gas to flow between the cylinder 200 and the condensation chamber 310.
[0095] In this embodiment, an air duct housing 440 is disposed between the outlet 312 of the condensation chamber 310 and the air inlet 220 of the cylinder 200 ; and the fan is disposed in the air duct housing 440 .

[0097] See also Figures 2 to 9 The clothes processing device further includes a filter 500, which is disposed in the drying air duct 300 and is used to filter hair in the air introduced from the air outlet 230 to the condenser 420. The filter 500 is located on a side of the evaporator 410 close to the air outlet 230.
[0098] The filter 500 may be partially located inside the drying air duct 300, or may be completely located inside the drying air duct 300, without specific limitation. When the filter 500 is partially located inside the drying air duct 300, the part of the filter 500 located inside the drying air duct 300 plays a filtering role, and the part located outside the drying air duct 300 plays a role of being taken by the user for easy replacement.
[0099] The filter 500 is located between the air outlet 230 and the evaporator 410. The air discharged from the air outlet 230 will be filtered by the filter 500 and then introduced to the evaporator 410. Therefore, even if the hair in the accommodating chamber 210 is introduced from the air outlet 230, it will be filtered by the filter 500 before passing through the evaporator 410, thereby preventing the hair from entering the evaporator 410 and the condenser 420 and affecting the normal operation of the drying component 400.
[0100] In this embodiment, an inlet 311 is provided in the condensation chamber 310 , and the inlet 311 of the condenser 420 is connected to the air outlet 230 of the cylinder 200 ; a filter 500 is provided at the inlet 311 of the condenser 420 .
[0101] See again Figures 2 to 9A heater 600 is provided at the condenser 420 in the condensation chamber 310 for heating the gas. The heater 600 is provided at a side of the condenser 420 facing away from the evaporator 410 .
[0102] The setting of the heater 600 can play an auxiliary heating effect, so as to provide more heat to the gas, thereby better drying the clothes.

Specifically, the lower end of the drain pipe 700 is connected to the drain pump in the outer cylinder to discharge the condensed water from the box 100 through the drain pump.
[0106] In this embodiment, the lower end of the drain pipe 700 is connected to the water guide port 240 on the cylinder 200 to introduce condensed water into the outer cylinder. In some implementations, the lower end of the drain pipe 700 discharges water out of the box 100 .
[0107] The inner cavity of the drain pipe 700 includes a first cavity 710 and a second cavity 720 connected in sequence. The first cavity 710 is located above the second cavity 720 , and the diameter of the first cavity 710 is larger than the diameter of the second cavity 720 .
[0108] In this embodiment, the diameter of the first lumen 710 gradually increases in the direction of the first lumen 710. Specifically, the first lumen 710 has a tapered structure that is larger at the top and smaller at the bottom.
[0109] In one embodiment, the diameter of the first lumen 710 is cylindrical, and the diameter of the first lumen 710 is constant in the up and down directions.
[0110] In this embodiment, the diameter of the second tube cavity 720 remains unchanged in the extension direction of the drain pipe 700.
[0111] In a specific embodiment, the diameter of the first lumen 710 gradually increases in the direction, the diameter of the second lumen 720 remains unchanged, the diameter of the lower end of the first lumen 710 is equal to the diameter of the upper end of the second lumen 720, and the lower end of the first lumen 710 is connected to the upper end of the second lumen 720.
[0112] In another specific implementation, the diameters of the first lumen 710 and the second lumen 720 remain unchanged, the diameter of the first lumen 710 is larger than the diameter of the second lumen 720 , and a step is formed at the connection between the lower end of the first lumen 710 and the second lumen 720 .
[0113] In some embodiments, the diameters of the first lumen 710 and the second lumen 720 are both tapered structures with a larger diameter at the top and a smaller diameter at the bottom. The upper end of the second lumen 720 is connected to the lower end of the first lumen 710 .
[0114] The inner cavity of the drain pipe 700 further includes a third lumen 730 ; the third lumen 730 is located at the upper end of the first lumen 710 . The diameter of the third lumen 730 is greater than the diameter of the second lumen 720 .
[0115] In this embodiment, a downwardly protruding drainage portion 330 is formed at the lower end of the drying air duct 300, and a drainage port extending vertically is provided on the drainage portion 330; the drainage pipe 700 is fixed to the outer periphery of the drainage portion 330 at the third tube cavity. The drainage pipe 700 is sleeved on the outer periphery of the drainage portion 330 at the outer periphery of the third tube cavity and is sealed and connected to the outer periphery of the drainage portion 330.
[0116] In one embodiment, the drain pipe 700 forms a detachable interface between the third lumen and the drain portion 330 so as to be connected via the detachable interface.
[0117] See again Figures 10 to 13 A float 800 is provided in the first tube cavity 710 to seal the first tube cavity 710, thereby effectively preventing heat from entering the drying air duct 300 through the drain pipe 700, thereby ensuring the drying efficiency.
[0118] The density of the float is less than that of water, so that the water can drive the float to move upward.
[0119] The float 800 is disposed in the drain pipe 700. When condensed water is discharged downward in the drain pipe 700, the condensed water drives the float 800 to float upward, so that the condensed water can be discharged downward from the drain pipe 700. When there is no condensed water in the drain pipe 700, the float 800 is attached to the peripheral side wall of the drain pipe 700 to block the gas exchange between the upper and lower sides of the float 800, so as to play a role of heat insulation.

[0121] In one embodiment, the diameter of the first tube cavity 710 is a conical structure with a larger diameter at the top and a smaller diameter at the bottom, and the circumference of the float 800 is attached to the circumference of the first tube cavity 710 to provide heat insulation.
[0122] In this embodiment, the diameter of the first lumen 710 gradually increases in the direction, the diameter of the second lumen 720 remains unchanged, and the lower part of the float 800 abuts against the connection between the first lumen 710 and the second lumen 720 .
[0123] In this embodiment, a protruding stopper 810 is provided above the float 800 in the drain pipe 700. The stopper 810 is located above the float 800. After the float 800 moves upward a preset distance, the stopper 810 can stop the float 800 to prevent the float 800 from falling out of the drain pipe 700.
[0124] In this embodiment, the stopper 810 is an annular structure, and a plurality of hollow holes penetrating from top to bottom are formed on the stopper 810 so that the condensed water can move downward through the stopper 810 .
[0125] The diameter of the hollow hole is smaller than the outer diameter of the float 800 to prevent the float 800 from slipping out of the drain pipe 700 upwards.
[0126] In this embodiment, the third tube cavity 730 is located at the upper end of the first tube cavity 710 , and the tube diameter of the third tube cavity 730 is larger than the outer diameter of the float 800 , so that the float 800 can be placed in the drain pipe 700 through the third tube cavity 730 .
[0127] In one embodiment, the stopper 810 is not provided in the drain pipe 700 , and the lower end of the drain portion 330 can stop the float 800 to prevent the float 800 from falling out of the drain pipe 700 .
[0128] In the present invention, the inner cavity of the drain pipe 700 includes a first cavity 710 and a second cavity 720 connected in sequence, the first cavity 710 is located above the second cavity 720, and the diameter of the first cavity 710 is larger than the diameter of the second cavity 720; a float 800 is arranged in the first cavity 710, and the lower end of the float 800 is sealed and fitted to the peripheral side wall of the second cavity 720 or the peripheral side of the first cavity 710. When the drain pipe 700 drains condensed water downward, the condensed water drives the float 800 to float upward, so that the condensed water in the drain pipe 700 can be discharged downward. When the drain pipe 700 is not drained, the float 800 is blocked in the drain pipe 700, so as to effectively prevent the gas outside the drying duct 300 from entering the drying duct 300 through the drain pipe 700, and ensure the efficient drying operation.
