Technical Field

[0001] This application relates to the field of clothing washing and care technology, and in particular to a dehumidification device and clothing treatment equipment. Background Technology

[0002] Taking washer-dryer combos as an example, in order to improve the drying speed during the drying stage and add fresh air deodorization functions, related technologies have emerged that introduce fresh air into the washer-dryer combo. Specifically, during the drying stage, as needed, fresh air from outside can be introduced into the garment processing chamber of the washer-dryer combo, and the hot and humid airflow flowing out of the garment processing chamber is generally directly discharged to the outside of the washer-dryer combo.

[0003] However, the hot and humid airflow directly discharged to the outside of the washer-dryer combo has a high temperature and humidity, which can have a certain adverse effect on the user's home environment and reduce the user's experience. Summary of the Invention

[0012] At least a portion of the air intake channel extends into the first sub-cavity, the air outlet is located on the side wall of the second sub-cavity, and the condensate flow path formed between the water inlet and the water outlet passes through at least the first sub-cavity.

[0013] In one embodiment, at least two sub-channels are formed in the heat exchange cavity, arranged in layers along the height direction of the heat exchange box. The sub-channels are connected in sequence to form a tortuous channel extending from top to bottom.

The box cover is provided with the water inlet, and the box body is provided with the heat exchange chamber, the water outlet, the air inlet channel, and the air outlet. The baffle is connected to the box cover.

[0016] In one embodiment, the dehumidification device further includes at least one partition disposed within the first sub-cavity, the partition dividing the first sub-cavity into a tortuous flow channel extending from top to bottom.

[0017] In one embodiment, the outlet is connected to the sub-channel located at the lowest layer, and the outlet is located on the side of the sub-channel located at the lowest layer away from the second sub-cavity.

[0018] In one embodiment, the cover is provided with a water passage cavity having multiple spray holes, and the water inlet is connected to the water passage cavity; each of the spray holes is connected to the sub-channel located at the uppermost layer.

In other words, there is not only a long heat exchange path between the airflow and the condensate, but also a large contact area between the airflow and the condensate, resulting in sufficient heat exchange. Therefore, without the need for heat exchange structures such as metal fins, sufficient heat exchange can be carried out between the condensate and the airflow, thereby enabling the dehumidification device to have a better condensation dehumidification effect.

Detailed Implementation

[0044] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0045] In the description of the embodiments in this application, it should be noted that the terms "top," etc., indicate the orientation or positional relationship based on the appendix. Figure 5 The orientation or positional relationship shown, including "height" and "lateral" indicators, is based on the attached... Figure 2 , Figure 3 and Figure 10 The directions or positional relationships shown are based on the attached... Figure 5 The top direction is shown, and "down" is based on the attached direction. Figure 5 The orientations shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application.

[0046] This application provides a dehumidification device 10, which is a device that uses condensate to condense and dehumidify hot and humid airflow. The condensate can be water or other cooling medium. In this application embodiment, the condensate is water.

[0047] Please see Figures 2 to 6 The heat exchange box 11 has a heat exchange cavity 111a and an inlet 112a, an outlet 111b, an air inlet channel 111d, and an air outlet 111c communicating with the heat exchange cavity 111a. The air inlet channel 111d extends along the height direction of the heat exchange box 11, and at least a portion of the air inlet channel 111d extends into the heat exchange cavity 111a. The height of the top of the air inlet channel 111d exceeds the height of the air outlet. Here, "exceeds" means that the airflow enters the heat exchange cavity 111a from a relatively high position and exits from the relatively low air outlet 111c.

[0048] The airflow entering from the air inlet 111d and the water flow entering from the water inlet 112a come into direct contact within the heat exchange chamber 111a. In other words, a condensate flow path is formed between the water inlet 112a and the water outlet 111b. The condensate flows into the heat exchange chamber 111a from the water inlet 112a and finally flows out through the water outlet 111b.

[0049] For example, the inlet 112a can be located above the outlet 111b, meaning that the condensate can flow from top to bottom.

[0050] An airflow path is formed between the air inlet channel 111d extending along the height direction of the heat exchange box 11 and the air outlet 111c. That is, the airflow flows upward along the air inlet channel 111d and flows into the heat exchange chamber 111a from the inside of the heat exchange chamber 111a, and then flows out through the air outlet 111c.

[0051] The condensate flowing into the heat exchange chamber 111a from the inlet 112a and the airflow flowing into the heat exchange chamber 111a from the inlet 111d come into direct contact and exchange heat in the heat exchange chamber 111a, absorbing the heat of the airflow. The water vapor in the airflow after heat exchange is cooled down and condenses into water droplets. The water droplets mix into the condensate and are finally discharged from the outlet 111b. In this way, the effect of condensation and dehumidification of the airflow is achieved.

[0052] The dehumidifier 10 of this application embodiment can be used in any suitable occasion. Exemplarily, this application embodiment describes the application of the dehumidifier 10 to a clothing processing device as an example.

[0053] For example, this application provides a garment processing device; please refer to [link to relevant documentation]. Figure 1 It includes a cylindrical assembly 20, an air guide device 30, and a dehumidifier 10 according to any embodiment of this application. The cylindrical assembly 20 is provided with a clothes processing chamber, an air inlet, and an air outlet; the air inlet and the air outlet are connected, and the air outlet 111c is connected to the outside; the air inlet is connected to the outside through the air guide device 30.

[0054] Clothing processing equipment can be dryers, washer-dryer combos, etc., and there are no restrictions. Clothing processing equipment can be either drum-type or impeller-type.

[0055] The air guide device 30 is equipped with a fan and a heating component. The air guide device 30 can heat the fresh air from the outside and introduce it into the clothing processing chamber through the air inlet. In the clothing processing chamber, the dry hot air flows over the surface of the wet clothes and exchanges heat and moisture with the wet clothes, absorbing the moisture in the clothes and turning into a humid hot air flow. The humid hot air flow flows out from the air outlet of the clothing processing chamber.

[0056] The air outlet of the clothing processing chamber is connected to the air inlet of the dehumidification device 10. The hot and humid airflow flowing out of the air outlet of the clothing processing chamber enters the dehumidification device 10 through the air inlet for condensation and dehumidification, forming a low-temperature dry airflow. The low-temperature dry airflow is discharged from the air outlet 111c and enters the surrounding environment.

[0057] In one embodiment, the air outlet 111c of the dehumidifier 10 can be connected to the detergent box, that is, the low-temperature dry airflow is discharged into the surrounding environment through the detergent box. In some embodiments, the air outlet 111c can also be directly connected to the outside.

[0058] It should be noted that the low-temperature dry airflow is relative to the humid and hot airflow; the temperature of the low-temperature dry airflow is lower than that of the humid and hot airflow. In the embodiments of this application, low temperature can be room temperature.

[0059] The dehumidification device 10 of this application embodiment is provided with a heat exchange box 11 having a heat exchange chamber 111a, a water inlet 112a, a water outlet 111b, an air inlet channel 111d, and an air outlet 111c. Since the air inlet channel 111d extends along the height direction of the heat exchange box 11, and at least a portion of the air inlet channel 111d extends into the heat exchange chamber 111a, and the height of the top of the air inlet channel 111d exceeds the height of the air outlet, the airflow flowing in from the air inlet channel 111d can enter the heat exchange chamber 111a from a relatively high position within the heat exchange chamber 111a, and... The condensate diffuses rapidly in the heat exchange chamber 111a and then flows to the relatively low-positioned air outlet. Meanwhile, the condensate flowing into the heat exchange chamber 111a from the water inlet 112a can directly and fully contact the airflow during its flow. In other words, the airflow and condensate not only have a long heat exchange path, but also a large contact area, resulting in sufficient heat exchange. Thus, without the need for heat exchange structures such as metal fins, the condensate and airflow can exchange heat sufficiently, thereby enabling the dehumidification device 10 to have a good condensation and dehumidification effect.

[0060] In addition, the dehumidifier 10 of this application embodiment can be used to condense and dehumidify the hot and humid airflow discharged from the clothing processing chamber of the clothing processing equipment. The airflow condensed and dehumidified by the dehumidifier 10 is discharged through the air outlet 111c and enters the indoor environment. That is to say, the airflow discharged into the surrounding environment has been condensed and dehumidified by the condenser, so it will not significantly affect the indoor temperature and humidity, reduce the impact on the indoor environment, and thus improve the user experience.

[0061] The heat exchange box 11 can have various structural forms; for example, please refer to [link to relevant documentation]. Figures 2 to 6The heat exchange box 11 may include a box body 111 and a box cover 112 covering the top of the box body 111. The box cover 112 is provided with a water inlet 112a. The box body 111 is provided with a heat exchange chamber 111a, a water outlet 111b, an air inlet channel 111d, and an air outlet 111c. That is to say, the heat exchange box 11 may be composed of a box body 111 and a box cover 112. In some embodiments, the heat exchange box 11 may not be composed of a box body 111 and a box cover 112. For example, the heat exchange box 11 may be an integral structure or it may be assembled from multiple shells.

[0062] Additionally, please see Figures 5 to 7 The cover 112 can be provided with a water passage chamber 112b having multiple spray holes 112c. The water inlet 112a is connected to the water passage chamber 112b, and the heat exchange chamber 111a is connected to each spray hole 112c. That is to say, the condensate enters the water passage chamber 112b from the water inlet 112a and is then sprayed into the heat exchange chamber 111a through the spray holes 112c. This allows the condensate to fully contact the humid and hot airflow flowing into the heat exchange chamber 111a, thereby enabling sufficient heat exchange between the condensate and the humid and hot airflow, and thus improving the condensation dehumidification effect.

[0063] In some embodiments, the cover 112 may not have a water passage cavity 112b.

[0064] Please see Figure 5 and Figure 7 The top of the air intake passage 111d has an air outlet 111e, through which the airflow entering the air intake passage 111d flows into the heat exchange chamber 111a. The air outlet 111e can be configured in various ways; for example, please refer to [reference needed]. Figure 5 and Figure 7 The air outlet 111e may include a first air outlet 111e1 facing the top wall of the heat exchange chamber 111a, that is, the airflow can flow into the heat exchange chamber 111a towards the top wall.

[0065] Further, please refer to Figure 5 and Figure 7 A condensate guide surface 112d can be formed in the area of ​​the top wall of the heat exchange cavity 111a facing the first air outlet 111e1. The airflow from the first air outlet 111e1 condenses on the condensate guide surface 112d to form condensate, and the condensate is introduced into the heat exchange cavity 111a through the condensate guide surface 112d.

[0066] Specifically, if the top of the air intake channel 111d is set as a closed end, that is, without the first air outlet 111e1, then some of the hot and humid airflow entering the air intake channel 111d will condense and form condensate after contacting the closed end of the air intake channel 111d. The condensate will flow back into the clothing processing chamber along the air intake channel 111d. Therefore, the first air outlet 111e1 can be set at the top of the air intake channel 111d. At the same time, a condensate guide surface 112d is set in the area of ​​the top wall of the heat exchange chamber 111a facing the first air outlet 111e1. Some of the hot and humid airflow flowing out from the first air outlet 111e1 will still condense and form condensate after contacting the condensate guide surface 112d. However, the condensate can be guided into the heat exchange chamber 111a through the condensate guide surface 112d and discharged from the outlet 111b along with the condensate. Thus, it is possible to avoid condensate dripping into the air intake channel 111d and flowing back into the clothing processing chamber as much as possible.

[0067] For example, please refer to Figure 5 There is a gap between the sidewall of the air inlet channel 111d and the sidewall of the heat exchange chamber 111a, meaning that the air inlet channel 111d does not contact the sidewall of the heat exchange chamber 111a. The condensate guide surface 112d can be an inclined surface with a higher center and lower edges. Preferably, the condensate guide surface 112d can be approximately a conical surface or a circular arc top. The condensate on the condensate guide surface 112d can flow into the heat exchange chamber 111a along the edges around the condensate guide surface 112d, thereby increasing the condensate flow velocity.

[0068] In another embodiment, the condensate guide surface 112d may also include a horizontal sub-surface and an inclined sub-surface, with the inclined sub-surface surrounding the periphery of the horizontal sub-surface and sloping downwards from the side connected to the horizontal sub-surface towards the side away from the horizontal sub-surface. Since the humid and hot airflow mainly flows into the heat exchange chamber 111a from the edge of the first air outlet 111e1, the central region of the condensate guide surface 112d may also be set as a horizontal surface, while the surrounding area may be set as an inclined surface.

[0069] In some embodiments, regardless of whether there is a gap between the sidewall of the air inlet passage 111d and the sidewall of the heat exchange chamber 111a, the condensate guide surface 112d can be configured as an inclined surface that slopes from one side to the opposite side.

[0070] In one embodiment, please refer to Figure 5 The vent 111e may also include a second vent 111e2, which is disposed on the side wall of the air intake channel 111d. That is, a portion of the hot and humid airflow flows out from the first vent 111e1 at the top of the air intake channel 111d, and another portion of the hot and humid airflow flows out from the second vent 111e2 on the side wall of the air intake channel 111d. This can increase the rate at which the hot and humid airflow flows into the heating chamber, thereby improving the heat exchange efficiency.

[0071] For example, please refer to Figure 5 The height of a portion of the sidewall of the intake passage 111d can be higher than the height of another portion of the sidewall, so that the top of the intake passage 111d can define a second air outlet 111e2 extending circumferentially along the intake passage 111d.

[0072] In one embodiment, please refer to Figure 3 , Figures 5 to 7 The dehumidification device 10 includes a baffle 14, which divides the heat exchange chamber 111a into a first sub-chamber 111a1 and a second sub-chamber 111a2. The second sub-chamber 111a2 is located on one side of the first sub-chamber 111a, and the first sub-chamber 111a1 and the second sub-chamber 111a2 are connected. At least a portion of the air inlet channel 111d extends into the first sub-chamber 111a1, which means that the air outlet 111e is located in the first sub-chamber 111a1. The air outlet 111c is located on the side wall of the second sub-chamber 111a2. The baffle 14 separates the air outlet 111e and the air outlet 111c, that is, the air outlet 111e and the air outlet 111c are located on opposite sides of the baffle 14. The condensate flow path formed between the water inlet 112a and the water outlet 111b passes through at least the first sub-chamber 111a1. In other words, the hot and humid airflow flows into the first sub-cavity 111a1 along the air inlet channel 111d, and directly contacts the condensate for heat exchange in the first sub-cavity 111a1. The low-temperature dry airflow formed after the heat exchange flows into the second sub-cavity 111a2, and is then discharged through the air outlet 111c.

[0073] Figure 3 The baffle 14 shown is connected to the lid 112. That is, the baffle 14 is disposed on the lid 112. When the lid 112 is placed on the box body 111, the baffle 14 extends into the heat exchange chamber 111a and separates the first sub-chamber 111a1 and the second sub-chamber 111a2. In some embodiments, the baffle 14 may also be disposed directly in the heat exchange chamber 111a without being connected to the lid 112.

[0074] The baffle 14 can block the flow of hot and humid air in the heat exchange chamber 111a. In other words, the hot and humid air flowing out of the air outlet 111e needs to bypass the baffle 14 before flowing to the air outlet 111c, instead of flowing directly to the air outlet 111c. This is equivalent to increasing the travel distance of the hot and humid air in the heat exchange chamber 111a. As a result, it can ensure that the hot and humid air can exchange heat fully, thereby further improving the condensation and dehumidification effect.

[0075] in addition, Figure 6The outlet 111b shown is connected to the first sub-cavity 111a1. That is to say, the condensate after heat exchange is discharged from the first sub-cavity 111a1, rather than from the second sub-cavity 111a2. This is equivalent to the low-temperature dry airflow entering the second sub-cavity 111a2 being separated from the condensate. Thus, water vapor in the condensate can be prevented from mixing into the low-temperature dry airflow as much as possible.

[0076] In one embodiment, please refer to Figures 8 to 10 The heat exchange cavity 111a has at least two sub-channels 111f1 arranged in layers along the height direction of the heat exchange box 11. Each sub-channel 111f1 is connected in sequence to form a bent channel 111f extending from top to bottom.

[0077] Specifically, the air inlet channel 111d and the water inlet 112a are connected to the bend channel 111f. The airflow entering the heat exchange chamber 111a from the air inlet channel 111d flows into the bend channel 111f, and the condensate entering the heat exchange chamber 111a from the water inlet 112a also flows into the bend channel 111f. In other words, as the condensate flows along the bend channel 111f, it directly contacts the hot and humid airflow flowing along the bend channel 111f in the same fluid channel for heat exchange. The bend channel 111f increases the travel distance of the hot and humid airflow and the condensate in the heat exchange chamber 111a, so that the condensate can fully contact the hot and humid airflow. Thus, the condensate and the hot and humid airflow can fully exchange heat in the heat exchange chamber 111a, thereby improving the condensation and dehumidification effect.

[0078] The air inlet channel 111d and the water inlet 112a can be connected to any of the sub-channels 111f1. More preferably, the air inlet channel 111d and the water inlet 112a can be connected to the uppermost sub-channel 111f1. That is, the hot and humid airflow enters the uppermost sub-channel 111f1 from the air inlet channel 111d and flows along the bend channel 111f to the lowermost sub-channel 111f1, and then flows out through the air outlet 111c. The condensate enters the uppermost sub-channel 111f1 from the water inlet 112a and flows along the bend channel 111f to the lowermost sub-channel 111f1, and then flows out through the water outlet 111b.

[0079] There are several ways to form multiple sub-channels 111f1 within the heat exchange cavity 111a. For example, please refer to [link to example]. Figures 8 to 10 For the dehumidification device 10 equipped with baffle 14, at least one baffle 13 can be provided in the first sub-cavity 111a1, and the baffle 13 divides the first sub-cavity 111a1 into a tortuous flow channel 111f extending from top to bottom. That is, the baffle 14, the baffle 13 and the side wall of the heat exchange cavity 111a can be used to define each sub-flow channel 111f1.

[0080] Figure 10 The outlet 111b shown is connected to the lowest sub-channel 111f1. In other words, after the heat exchange, the condensate flows to the lowest sub-channel 111f1 and flows out directly from the lowest sub-channel 111f1 without flowing into the second sub-cavity 111a2. This is equivalent to separating the low-temperature dry airflow entering the second sub-cavity 111a2 from the condensate. As a result, water vapor in the condensate can be prevented from mixing into the low-temperature dry airflow as much as possible.

[0081] Further, please refer to Figure 10 The outlet 111b can be set on the side of the lowest sub-channel 111f1 away from the second sub-cavity 111a2. This means that the low-temperature drying airflow and the condensate flow in opposite directions in the lowest sub-channel 111f1. This can better prevent water vapor in the condensate from mixing into the low-temperature drying airflow.

[0082] In some embodiments, the outlet 111b can also be connected to the second sub-cavity 111a2, which means that the condensate after heat exchange flows from the sub-channel 111f1 located at the bottom of the bend channel 111f into the second sub-cavity 111a2, and then flows out from the outlet 111b.

[0083] Please see Figure 8 and Figure 10 Each sub-channel 111f1 can be connected sequentially through the water inlet 13a. The water inlet 13a can be formed in various ways; for example, please refer to [link to example]. Figure 8 and Figure 10 A portion of the edges of the partition plates 13 are spaced apart from the sidewall of the heat exchange chamber 111a, forming a water inlet 13a at the gap between them. Another portion of the edges of the partition plates 13 are spaced apart from the baffle plates 14, also forming a water inlet 13a at the gap between them. In other embodiments, a portion of the edges of each partition plate 13 may be spaced apart from the sidewall of the heat exchange chamber 111a to form a water inlet 13a at the gap between them.

[0084] In some embodiments, the partition 13 may not be spaced apart from the sidewall of the baffle 14 and / or the heat exchange chamber 111a. For example, the water inlet 13a may be directly provided on the partition 13.

[0085] In other embodiments, a portion of the edge of a partition 13 may be spaced apart from the sidewall of the baffle 14 and / or the heat exchange chamber 111a, while a water inlet 13a may be provided on another portion of the partition 13.

[0086] In some embodiments, the baffle 14 may not be provided. For example, multiple baffles 13 can directly divide multiple sub-channels 111f1 within the heat exchange cavity 111a.

[0087] Further, please refer to Figure 9 and Figure 10 For the cover 112 with a water cavity 112b, each spray hole 112c can be connected to the uppermost sub-channel 111f1. That is, the condensate is sprayed into the uppermost sub-channel 111f1 through the spray holes 112c. In some embodiments, a portion of the spray holes 112c can be connected to the uppermost sub-channel 111f1, and another portion of the spray holes 112c can be connected to the second sub-cavity 111a2. This means that after the airflow from the bend channel 111f flows into the second sub-cavity 111a2, it can also exchange heat with the condensate sprayed from the spray holes 112c in the second sub-cavity 111a2.

[0088] In some embodiments, for a cover 112 that does not have a water passage 112b, the water inlet 112a can be directly connected to the uppermost sub-channel 111f1.

[0089] In one embodiment, please refer to Figures 11 to 13 At least some of the sub-channels 111f1 may also be equipped with heat exchange components 12. That is to say, heat exchange components 12 may be installed in all sub-channels 111f1 or only in some sub-channels 111f1. The heat exchange components 12 may be heat dissipation fins, heat conduction plates or other components with heat exchange functions.

[0090] When the hot and humid airflow flowing along the bend channel 111f passes through the heat exchanger 12, the hot and humid airflow can exchange heat with the heat exchanger 12. That is to say, the heat exchanger 12 and the condensate can work together to condense and dehumidify the hot and humid airflow. At the same time, the condensate can also exchange heat with the heat exchanger 12 to absorb the heat from the heat exchanger 12. Thus, the condensation and dehumidification effect can be further improved.

[0091] There are several ways in which the heat exchanger 12 can be arranged within the sub-channel 111f1. For example, please refer to [link to example]. Figure 11 and Figure 13 Heat exchange elements 12 can be installed on at least part of the partition 13. Figure 13 In this embodiment, heat exchange components 12 are provided on both ends of the same partition 13 on opposite sides. In some embodiments, heat exchange components 12 may be provided on only one end face.

[0092] It is understood that in some embodiments, the heat exchanger 12 may not be provided in the sub-channel 111f1.

[0093] In some embodiments, the heat exchange cavity 111a may not have a bend in the flow channel 111f.

[0094] In one embodiment, the garment processing device includes a condensing device with a condensing chamber, and an internal circulation path is formed within the garment processing device, passing through the garment processing chamber, the condensing chamber and the air guide device 30, with the water outlet 111b connected to the condensing chamber.

[0095] Similar to the dehumidifier 10, the condenser is also used to dehumidify and cool the hot and humid airflow. However, the condenser and dehumidifier 10 have different application scenarios. Specifically, the garment handling equipment can have two circulation paths: one is the external circulation path, as described above, where fresh air is introduced into the garment handling equipment, and the hot and humid airflow flowing out of the garment handling chamber is condensed and dehumidified by the dehumidifier 10 before being discharged into the surrounding environment; the other is the internal circulation path, which passes through the garment handling chamber, the condenser chamber of the condenser, and the air guide device 30. In other words, it is the path through which the airflow circulates within the garment handling equipment. Accordingly, the garment handling equipment can be configured with an external circulation mode that allows the airflow to flow along the external circulation path and an internal circulation mode that allows the airflow to flow along the internal circulation path.

[0096] In internal circulation mode, the air guide device 30 guides the dry hot airflow into the clothing processing chamber through the air inlet. Inside the chamber, the dry hot airflow flows over the surface of the wet clothing, exchanging heat and moisture, absorbing the moisture and becoming humid hot air. This humid hot airflow exits from the air outlet of the clothing processing chamber and flows into the condenser. The humid hot airflow is condensed and dehumidified by the condensate in the condenser, forming a low-temperature dry airflow. This low-temperature dry airflow enters the air guide device 30 and is heated by the heater inside, forming a dry hot airflow. The dry hot airflow then re-enters the clothing processing chamber, and this cycle repeats to dry the clothing.

[0097] The outlet 111b of the dehumidifier 10 is connected to the condensation chamber of the condenser, meaning that the condenser and the dehumidifier 10 can share a water path. In external circulation mode, the condensate after exchanging heat with the humid airflow in the dehumidifier 10 flows into the condenser through the outlet 111b of the dehumidifier 10 and is discharged through the condenser. In internal circulation mode, the condensate flows through the dehumidifier 10 and flows into the condenser from the outlet 111b of the dehumidifier 10 to exchange heat with the humid airflow. The condensate after heat exchange is discharged from the condenser.

[0098] The external circulation mode primarily utilizes fresh air from the environment to dry the clothes in the garment processing chamber. Because the humidity of the fresh air is relatively low, the resulting hot airflow after being heated by the heating device also has low humidity. As the hot airflow flows through the garment processing chamber, it accelerates heat and air exchange efficiency, improving drying efficiency. Additionally, the fresh air can also expel odors from the garment processing chamber into the surrounding environment, thus removing unpleasant smells.

[0099] As for the internal circulation mode, on the one hand, the airflow can reduce heat loss, reduce energy consumption, and improve efficiency during the internal circulation process; on the other hand, it can also reduce the impact on the indoor environment.

[0100] It is understood that clothing processing equipment is not limited to having both external circulation mode and internal circulation mode. In some implementations, clothing processing equipment may only have external circulation mode and no internal circulation mode.
