Technical Field

[0001] The present invention relates to the technical field of clothing care, and in particular to an exhaust port component of an exhaust device and a washer-dryer. Background Art

[0002] Currently available clothes drying devices generally use condensation cycle drying and / or direct condensation. The direct drying method takes a short time and is less likely to wrinkle clothes. However, the gas after drying is mostly high-temperature and high-humidity gas. Directly discharging the high-temperature and high-humidity gas from the inner drum into the room will cause the humidity and temperature of the indoor air to be too high. The high-temperature and high-humidity indoor air then enters the inner drum through the fresh air duct, resulting in the inability to ensure long-term air quality, which is prone to damage and pollution during clothing drying.

[0003] In other prior arts, the condensed high-temperature and humid air is cooled and dehumidified by the heat exchange device and then discharged outside the clothes drying device, and the liquid flows out and pollutes the ground. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0013] Furthermore, the exhaust port assembly can be detachably installed in the exhaust passage.

[0014] Furthermore, the exhaust port includes a plurality of air holes.

[0015] Furthermore, the exhaust port faces away from the ground, and the liquid in the gas having a humidity difference with the outside world flows back under the action of gravity.

[0016] Correspondingly, the present invention also provides a washer-dryer comprising an exhaust port assembly of the exhaust device as described in any one of the above items.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides an exhaust device for an exhaust device, in which the gas discharged from the washing and drying machine with a humidity difference from the outside world is discharged into the exhaust channel, and the liquid refluxes after being blocked by the baffle, and is discharged together with the condensed water generated by drying clothes inside the washing and drying machine, preventing a small amount of liquid in the gas from flowing to the ground after being ejected with the gas, and at the same time, the gas is discharged to the outside of the washing and drying machine from the exhaust port; and the recessed portion design of the first baffle and the combined design of the first baffle and the second baffle can achieve a higher liquid blocking effect and reflux effect.

[0030] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the terms "having," "including," and "comprising" used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0031] See also Figure 4-5 The present invention provides an exhaust port assembly of an exhaust device, which is installed in an exhaust channel 33 of the exhaust device. The exhaust port assembly includes a baffle, on which an exhaust port 32 is provided. The baffle is used to block liquid in the gas with a humidity difference with the outside world from entering the exhaust channel, and at the same time, the gas is discharged from the exhaust port to the outside of the washer-dryer.

[0032] That is, after the gas with a humidity difference from the outside enters the exhaust channel 33, the liquid refluxes after being blocked by the baffle, and the gas is discharged from the exhaust port 32 to the outside of the washer-dryer.

[0033] The exhaust device 30 is installed on the inner wall or outer wall of the housing of the washing and drying machine. Figure 1 , the exhaust device 30 is installed on the outer wall of the shell, see the appendix of the manual Figure 2 The exhaust device 30 is installed on the inner wall of the shell to prevent the liquid in the gas from flowing back before the gas is discharged to the outside of the washing and drying machine.

[0034] The exhaust device 30 includes an air inlet 31, an exhaust channel 33 and an exhaust port assembly; wherein, the air inlet 31, the exhaust channel 33 and the exhaust port assembly form an exhaust passage; the air inlet 31 guides the gas discharged from the washer-dryer with a humidity difference from the outside into the exhaust channel 33, the liquid in the gas refluxes in the path of the exhaust passage, and the gas is discharged from the exhaust port assembly to the outside of the washer-dryer.

[0035] The exhaust device 30 is installed after the dehumidification system, and the air inlet 31 of the exhaust device 30 is installed at the air outlet of the dehumidification system; the dehumidification system cools and dehumidifies the hot and humid air in the outer drum 82 of the washer-dryer to form gas with a humidity difference from the outside, and discharges it to the exhaust device 30.

[0036] In the prior art, the washing and drying mode of a washing and drying machine can be a condensing type and / or a direct exhaust type. In the condensing type, the condenser is connected to the outer drum and is used to condense the hot and humid air entering the condenser from the outer drum. The condensed air is circulated to the inner drum, and the condensed water is discharged through the drain pipe. The subsequent direct exhaust washing and drying method shortens the drying time of the condensing type and discharges the hot and humid air in the washing and drying machine through the exhaust duct. The direct exhaust type can be used in combination with the condensing type to shorten the drying time, and can also introduce fresh air from outside the washing and drying machine, and at the same time discharge the hot and humid air from the washing and drying machine. The exhaust device 30 provided by the present invention is installed on the exhaust duct of the hot and humid air to reduce or avoid the liquid in the hot and humid air from being sprayed out.

[0037] In addition, a heat exchanger can also be provided in the direct-exhaust washing and drying mode. The hot and humid air from the inner and outer drums passes through the exhaust duct and first enters the heat exchanger for cooling and dehumidification. Then, it enters the exhaust device 30 provided by the present invention to reflux the liquid, and the gas is ejected from the exhaust device 30. Therefore, the exhaust device 30 provided by the present invention can also be installed after the heat exchanger. As can be seen, in the present invention, the exhaust device is installed after the dehumidification system, and the air inlet of the exhaust device is installed at the outlet of the dehumidification system. The dehumidification system includes an exhaust duct and / or a heat exchanger for discharging the hot and humid air. The outlet can be the outlet of the exhaust duct or the outlet of the heat exchanger.

[0038] Specifically, refer to Figures 4 to 6 The number of baffles is at least one. Exhaust port 32 includes a plurality of air holes. Specifically, the plurality of air holes are located on first baffle 34, forming exhaust port 32. The air holes occupy 1 / 3-1 / 2 of the total area of ​​the first baffle, ensuring that gas can pass through while preventing liquid from being ejected.

[0039] The baffle includes a first baffle 34, which is provided with a recessed portion that is recessed toward the exhaust passage 33. Specifically, a downwardly-facing recessed portion is provided in the middle of the first baffle 34. After a small amount of liquid carried in the ejected gas passes through the first baffle 34, the liquid is blocked by the first baffle 34 and flows back downward along the recessed portion. Specifically, the first baffle 34 includes a first inclined surface 341 and / or a second inclined surface 342. Liquid in the gas having a humidity difference with the outside world flows back along the first inclined surface 341 and / or the second inclined surface 342. Specifically, the first inclined surface 341 and / or the second inclined surface 342 are inclined toward the exhaust passage, forming a downwardly-facing recessed portion. Liquid in the exhaust gas flows back along the first inclined surface 341 and / or the second inclined surface 342. The first inclined surface 341 and the second inclined surface 342 may be connected to each other, or a transition surface may be provided.

[0040] In this embodiment, the baffle also includes at least one second baffle 35 arranged along the extension direction of the exhaust channel. The second baffle 35 is provided with a plurality of air holes. The second baffle 35 is located below the first baffle 34. The gas with a humidity difference with the outside world first passes through the second baffle 35 and then through the first baffle 34.

[0041] Specifically, a blocking portion 351 is provided in the middle of the second baffle 35, and a plurality of air holes are provided at both ends of the blocking portion 351. Liquid in the gas with a humidity difference from the outside is blocked by the blocking portion 351 in the middle of the second baffle 35 and then flows back. After being ejected, the gas with a humidity difference from the outside first passes through the second baffle 35. The liquid in the gas is blocked by the blocking portion 351 in the middle and then flows back. The gas is discharged through the air holes, effectively preventing the discharged gas from blowing out the liquid. The gas is then discharged through the plurality of air holes (i.e., the exhaust port 32) on the first baffle 34. The upper and lower baffle design increases the movement resistance of the gas with a humidity difference from the outside to a certain extent, preventing the gas from blowing out water. The discharged gas undergoes two condensations within the entire exhaust device 30, and the condensed liquid flows back into the drainage pipe of the dehumidification system and is discharged along the drainage pipe of the dehumidification system.

[0042] In this embodiment, the first baffle 34 and the second baffle 35 are integrally formed and detachably mounted within the exhaust passage 33. In other embodiments, the second baffle 35 may not be included, and the gas with a humidity difference from the outside is blocked and condensed only once by the first baffle 34. The first baffle 34 may be detachably mounted on the exhaust passage 33 or integrally formed with the exhaust passage 33.

[0043] Figure 5 The exhaust port assembly is detachably installed in the exhaust passage 33 as a whole.

[0044] Preferably, in order to achieve a better reflux effect, when the exhaust device is installed on the surface of the washer-dryer housing, the exhaust port 32 faces away from the ground, and the liquid in the gas with a humidity difference from the outside world flows back under the action of gravity.

[0045] In addition, the exhaust port assembly also includes a seal member disposed at the exhaust port, which is configured to open and close the exhaust port. The seal member can be configured in a plate or sheet-like structure, and is pivotally connected to the exhaust port to open or close the exhaust port as needed. In the non-exhaust state, the seal member seals the flow channel.

[0046] Furthermore, the exhaust port assembly in the exhaust device 30 is higher than other components of the exhaust device 30, for example, higher than the air inlet 31 of the exhaust device 30. It can be understood that there is a height difference between the air inlet 31 and the exhaust port assembly, and the exhaust port assembly is higher than the air inlet, which enhances the barrier effect on liquid in the exhaust gas, preventing the liquid from flowing directly to the ground and better achieving liquid backflow.

[0047] In addition, reference Figure 3 The present invention also relates to an exhaust device 30 , comprising the above-mentioned exhaust port assembly, an air inlet 31 and an exhaust channel 33 .

[0048] The flow path of the gas with a humidity difference from the outside world in the exhaust passage is non-linear. It can be understood that the exhaust passage 33 is non-linear or the air inlet and the exhaust port are not on the same plane, making the exhaust passage non-linear, increasing the blocking effect on the liquid in the exhaust gas, and increasing the contact area between the gas and the exhaust passage, thereby increasing the condensation effect of the gas in the exhaust passage.

[0049] The cross-sectional area of ​​the exhaust port is larger than that of the inlet port. Specifically, the cross-sectional area of ​​the exhaust channel 33 gradually increases from the inlet port to the exhaust port. This can be understood as the width of the exhaust channel 33 gradually increasing from the inlet port to the exhaust port. This increase in cross-sectional area increases the contact area with the liquid, increasing resistance to the liquid and increasing the contact area for forming the condensation effect. Specifically, the exhaust channel 33 includes sidewalls whose width gradually decreases from top to bottom, reducing resistance to liquid backflow and preventing liquid overflow.

[0050] In addition, to facilitate the installation of the exhaust device 30, the exhaust device 30 also includes a mounting portion, which is located on both sides of the air inlet 31 and is used to be installed at the air outlet of the dehumidification system. Specifically, the mounting portion is screwed onto the exhaust channel or air outlet of the dehumidification system of the washer-dryer.

[0051] Preferably, the air inlet 31 is equipped with a filter 311 to filter the gas entering the exhaust channel. The filter 311 can filter out fine impurities carried in the gas to prevent the exhaust gas from being too impure and affecting the indoor air quality.

[0052] After the exhaust passage 33 and the air inlet 31 are integrally formed, the filter 311 is installed in the air inlet 31 .

[0053] Accordingly, the present invention also provides a washer-dryer 100, referring to Figure 1-2 The washer-dryer further comprises: a housing, an inner drum 81, an outer drum 82, a fresh air duct 1 for introducing fresh air from outside into the device, a connecting duct 6, and an exhaust duct 2 for discharging hot and humid air from the device.

The outer drum 82 is provided with an exhaust inlet.

[0056] Fresh air duct 1 has a fresh air inlet at one end, located on the front panel or upper roof of the cabinet. This means that fresh air is connected to the outside air at one end. Air outside the cabinet enters the fresh air duct through the fresh air inlet and then passes through inner tube 81 to condenser 4. In short, fresh air duct 1 conveys fresh air from outside through connecting duct 6, into inner tube 81, and ultimately into condenser 4. Preferably, an air filter is provided on fresh air duct 1 to purify air entering the cabinet from within and / or from outside.

[0057] It can also include an air inlet module 20, the other end of which is connected to the inner cylinder 81.

[0058] Exhaust duct 2, one end of the exhaust duct 2 is the exhaust inlet set in the outer tube, and the other end is connected to the heat exchange device 10; the hot and humid air in the inner tube 81 first enters the outer tube 82 through the hole on the inner tube 81, and then enters the exhaust duct 2 from the exhaust inlet and is discharged.

[0059] The washer-dryer may also include a condenser 4, which is connected to the outer drum and is used to condense the hot and humid air entering the condenser 4 from the outer drum 82. The hot and humid air in the inner drum 81 enters the space between the inner and outer drums through the holes in the inner drum 81, and then enters the condenser 4 through the holes in the outer drum. The condenser 4 condenses the hot and humid air entering the condenser from the outer drum. The other end of the condenser is connected to the inner drum 81, so that the condensed air is heated by the heating assembly 51 in the circulating air duct 5 under the action of the fan volute 52 and then supplied to the inner drum 81. The condensed water flows into the drain pump 71 along with the condensed water. The water is then discharged through the drain pipe 7 by the action of the drain pump 71.

[0060] The circulating air duct 5 has one end connected to the condenser 4 and the other end connected to the inner cylinder 81 ; after the air passes through the condenser 4 and is condensed, it is supplied to the inner cylinder 81 through the circulating air duct 5 .

[0061] Preferably, a heating component 51 and a fan volute 52 are provided on the circulating air duct 5. The hot and humid air in the inner tube 81 enters the outer tube 82 through the inner tube 81, and then enters the condenser 4 through the holes on the outer tube 82. The gas condensed by the condenser 4 enters the circulating air duct 5 under the action of the fan volute 52, and is heated by the heating component 51 and circulated to the inner tube 81 to dry the clothes.

[0062] The washer-dryer may also include a heat exchanger 10 for cooling and dehumidifying hot and humid air. High-temperature and high-humidity air enters the heat exchanger 10 through the exhaust duct 2. If the heat exchanger 10 is not present, the exhaust device 30 provided above can be installed on the exhaust duct 2. If the heat exchanger 10 is present, the exhaust device 30 provided above is installed after the heat exchanger 10, specifically on the inner or outer casing of the washer-dryer.

[0063] The inner cylinder 81 is connected to the outer cylinder 82, and the outer cylinder 82 is provided with an exhaust inlet to discharge the hot and humid air in the inner cylinder 81 after being processed by the heat exchange device 10. One end of the exhaust duct 2 is connected to the exhaust inlet of the outer cylinder 82, and the other end is connected to the heat exchange device 10.

[0064] Specifically, refer to Figure 6 The heat exchange device 10 includes an upper shell 11, a lower shell 13, a water channel structure, a heat conducting plate 123 and an air channel structure. Preferably, the water channel structure, the heat conducting plate 123 and the air channel structure are all made of heat conducting materials.

[0065] The heat conducting plate 123 is located between the water channel structure and the air channel structure. A drain port is provided on the heat conducting plate 123. Preferably, the edge of the heat conducting plate 123 is bent toward the water channel structure to form a baffle, that is, the baffle and the heat conducting plate 123 form an open groove, and the water channel structure is located in the groove.

[0066] The water channel structure includes a plurality of upper fins 1211, with water channels formed between adjacent upper fins 1211.

Air inlet 132 is higher than and larger than air outlet 131 to prevent airflow disturbance. Cooling medium outlet 133 is lower than cooling medium inlet 111, air inlet 132, and air outlet 131 to drain condensed water.

[0068] The air inlet 31 of the ventilation device 30 is installed on the air outlet 131 of the heat exchange device 10, and guides the gas discharged from the washer-dryer with a humidity difference from the outside into the exhaust channel, so that the liquid in the gas flows back after passing through the blocking structure and flows back into the heat exchange device 10.

[0069] In some embodiments, the washer-dryer may be a portable dryer or an all-in-one washer-dryer.

[0070] The present invention provides an exhaust device for an exhaust device, in which gas discharged from a washing and drying machine with a humidity difference from that of the outside world enters an exhaust channel 33, is blocked by a baffle, and liquid refluxes, and is discharged together with condensed water generated by drying clothes inside the washing and drying machine, thereby preventing a small amount of liquid in the gas from flowing to the ground after being ejected with the gas.
