Description

Technical Field

[0001] This invention belongs to the field of garment processing technology, and particularly relates to an inner tube assembly, garment processing equipment and control method. Background Technology

[0002] In existing water-cooled drying garment processing equipment, after the airflow dries the clothes inside the inner drum, it carries water vapor to the outer drum and then enters the condenser duct. After condensation, the vapor is reheated and returned to the inner drum. In the drying duct, heat exchange occurs between the condensate and the airflow, causing the water vapor in the airflow to condense into condensate before being discharged.

[0003] However, the above-mentioned condensation method has many technical bottlenecks. First, due to the limited humidity carrying capacity of the air, when the humid air inside the inner drum is close to saturation, the evaporation rate of moisture in the clothes decreases significantly, resulting in a decrease in drying efficiency and a longer drying time. Second, the existing condensation structure is usually located outside the inner drum, and the airflow must be discharged from the inner drum before condensation and dehumidification can be carried out, resulting in a long airflow path and significant heat loss. Finally, in order to improve the dehumidification effect, it is usually necessary to increase the heating power or extend the drying time, which not only increases energy consumption but may also damage the clothes due to high temperature, affecting their service life and wearing experience.

When the garment processing equipment is in the drying stage and / or the judging stage, it acquires the temperature inside the inner drum and the temperature of the cooling water in the cooling water chamber. Based on the temperature inside the inner cylinder and the temperature of the cooling water in the cooling water chamber, determine whether it is necessary to replace the cooling water in the cooling water chamber. Based on the determination result of whether the cooling water in the cooling water chamber needs to be updated, the water pump is controlled to run or remain stopped.

[0018] Compared with the prior art, the main advantages of the present invention are as follows: During the drying process, the airflow carrying water vapor inside the inner drum enters the heat exchange chamber directly through the air inlet, where it exchanges heat efficiently with the cooling water in the cooling water chamber through the cavity wall between the two chambers. Since the heat exchange chamber is located closer to the clothes and the cooling water chamber is located further away, the heat from the humid air is rapidly transferred to the cooling water in the cooling water chamber through the cavity wall as it flows through the heat exchange chamber. This causes the water vapor in the humid air to condense rapidly into liquid water on the surface of the heat exchange chamber wall. Under gravity, the liquid water then collects within the heat exchange chamber and is promptly discharged through the flow outlet on the side wall, thus efficiently removing moisture from the airflow. Compared to existing technologies where the airflow needs to pass through a long duct before condensation, this application completes condensation and dehumidification before the airflow exits the inner drum, effectively shortening the condensation path, reducing heat loss and air resistance, and significantly improving the dehumidification efficiency per unit time, thereby significantly shortening the overall drying time.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0025] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0026] Existing water condensation methods in garment processing equipment have several technical bottlenecks. First, when the humid air inside the inner drum is close to saturation, the rate of moisture evaporation from the clothes decreases significantly, leading to reduced drying efficiency and extended drying time. Second, existing condensation structures are usually located outside the inner drum, requiring airflow to exit from the inner drum before condensation and dehumidification can occur, resulting in a longer airflow path and greater heat loss. Finally, to improve dehumidification, it is usually necessary to increase heating power or extend drying time, which not only increases energy consumption but may also damage the clothes due to high temperatures, affecting their lifespan and wearing experience. This invention creatively provides an inner cylinder assembly for a garment processing device. The inner cylinder assembly includes an inner cylinder with an inner cylinder opening at one axial end and an inner cylinder bottom at the other axial end. The inner cylinder bottom has a heat exchange chamber and a cooling water chamber that are not connected to each other. The heat exchange chamber is closer to the inner cylinder opening than the cooling water chamber. The end wall of the heat exchange chamber has a heat exchange chamber air inlet, and the side wall of the heat exchange chamber has a flow outlet. The end wall of the cooling water chamber has a cooling water outlet. At least part of the airflow in the inner cylinder can enter the heat exchange chamber through the heat exchange chamber air inlet and then exit the heat exchange chamber through the flow outlet. External cooling water can enter the cooling water chamber through the cooling water outlet, or the cooling water in the cooling water chamber can be discharged through the cooling water outlet. When the airflow flows through the heat exchange chamber, it exchanges heat with the cooling water in the cooling water chamber through the cavity wall between the heat exchange chamber and the cooling water chamber. This causes water vapor in the humid air to condense into liquid water, which then collects in the heat exchange chamber under gravity and is discharged in time through the flow outlet, thereby efficiently removing moisture from the airflow.

[0027] Example 1 <Inner Cylinder Assembly> like Figures 1 to 4 As shown, this embodiment provides an inner cylinder assembly for a garment processing device; the inner cylinder assembly includes an inner cylinder 1, the inner cylinder 1 includes an inner cylinder peripheral wall 11; one axial end of the inner cylinder peripheral wall 11 is provided with an inner cylinder opening 12, and the other axial end of the inner cylinder peripheral wall 11 is provided with an inner cylinder bottom 13; the inner cylinder bottom 13 is provided with a heat exchange chamber 241 and a cooling water chamber 242 that are adjacent to each other in the axial direction of the inner cylinder 1 and are not connected to each other, and the heat exchange chamber 241 is closer to the inner cylinder opening 12 than the cooling water chamber 242; The heat exchange chamber 241 has an air inlet 231 on its end wall away from the cooling water chamber 242. The air inlet 231 connects the interior of the inner cylinder 1 and the heat exchange chamber 241 and is used to input at least part of the airflow in the inner cylinder 1 into the heat exchange chamber 241. The side wall of the heat exchange chamber 241 has a flow port 111 for discharging the airflow and condensate in the heat exchange chamber 241. The end wall of the cooling water chamber 242 away from the heat exchange chamber 241 is provided with a cooling water inlet 232. The cooling water inlet 232 is connected to the cooling water chamber 242 and is used to input cooling water into the cooling water chamber 242 or to discharge cooling water from the cooling water chamber 242. When the airflow flows through the heat exchange chamber 241, it exchanges heat with the cooling water in the cooling water chamber 242 through the cavity wall between the heat exchange chamber 241 and the cooling water chamber 242.

[0028] In this way, the following technical effects can be achieved: (1) Since the condensation process is completed directly in the heat exchange chamber 241, the high-temperature airflow does not need to pass through a long external air duct to achieve efficient dehumidification, reducing the heat loss during the transmission process; at the same time, the cooling water in the cooling water chamber 242 continuously exchanges heat with the hot airflow in the heat exchange chamber 241, which can make full use of the cooling capacity of the cooling water and effectively ensure the condensation efficiency; on the basis of the above-mentioned efficient condensation, the ideal dehumidification effect can be achieved without adding additional heating power or excessively extending the drying time; therefore, this application can significantly reduce heating energy consumption and overall machine energy consumption while ensuring the drying effect, and achieve energy-saving drying; (2) Because this application improves the dryness of the airflow through efficient condensation dehumidification, the moisture content of the air returning to the inner drum 1 to participate in the circulating drying is significantly reduced, and the moisture in the clothes can evaporate continuously and quickly, avoiding the problem of drying stagnation caused by the saturation of humid air; in this process, there is no need to use excessively high-temperature heated air to forcibly increase the evaporation rate, so the clothes can be dried at a lower drying temperature; the lower temperature effectively reduces the heat damage to the clothing fibers caused by high temperature, avoiding problems such as shrinkage, fading, and hardening of clothes caused by overheating, thereby better protecting the quality of the clothes and extending the service life and wearing experience of the clothes; (3) The heat exchange chamber 241 and the cooling water chamber 242 are integrated in the existing structural space of the bottom 13 of the inner cylinder, and the two are arranged adjacent to each other in the axial direction. They do not occupy the effective clothing processing space inside the inner cylinder 1, nor do they increase the additional structural volume outside the inner cylinder 1. Compared with the prior art, which requires the separate installation of condensers and corresponding air ducts between the outer cylinder and the inner cylinder or inside the box, the inner cylinder assembly structure of this application is more compact, which is conducive to the miniaturization and lightweight design of clothing processing equipment. At the same time, it reduces the number of parts, reduces manufacturing costs and assembly complexity.

[0029] Furthermore, a first detection element is provided inside the inner cylinder 1 for detecting the temperature inside the inner cylinder 1; a second detection element is provided inside the cooling water chamber 242 for detecting the temperature of the cooling water inside the cooling water chamber 242. The inner cylinder assembly also includes a water pump 33, which is located outside the inner cylinder 1 and is connected to the cooling water inlet 232. The controller of the garment processing equipment is communicatively connected to the water pump 33, and the controller is configured to: control the operation of the water pump 33 according to the temperature inside the inner drum 1 and the temperature of the cooling water in the cooling water chamber 242, so that the cooling water inlet 232 inputs new cooling water into the cooling water chamber 242 and discharges old cooling water from the cooling water chamber 242; or, control the water pump 33 to stop operating, so that the cooling water inlet 232 neither inputs new cooling water into the cooling water chamber 242 nor discharges old cooling water from the cooling water chamber 242; that is, by controlling the operation of the water pump 33, the cooling water in the cooling water chamber 242 can be renewed. The temperature inside the inner drum 1 is either the temperature of the clothes inside the inner drum 1 or the temperature of the airflow.

[0030] The following describes the formation of the cooling water flow path. The cooling water inlet 232 is located on the axis of the inner cylinder 1. The inner cylinder assembly also includes a drive shaft 31, a cooling water pipe 321, and a water pump 33. The drive shaft 31, the cooling water pipe 321, and the water pump 33 are all located outside the inner cylinder 1. The drive shaft 31 includes a first shaft end 311 and a second shaft end 312. The first shaft end 311 is located at the cooling water inlet 232 and extends into the cooling water chamber 242. The first shaft end 311 is driven to connect with the inner cylinder 1. The first shaft end 311 is provided with a first shaft water inlet 313, and the second shaft end 312 is provided with a second shaft water inlet 314. A cooling water channel 315 is formed inside the drive shaft 31. The cooling water chamber 242, the first shaft water inlet 313, the cooling water channel 315, the second shaft water inlet 314, the cooling water pipe 321 and the water pump 33 are connected in sequence to form a cooling water flow path.

[0031] In this way, the following technical effects can be achieved: (1) The cooling water inlet is set on the inner cylinder axis, so that the cooling water can enter and exit along the rotation axis of the inner cylinder, which simplifies the sealing structure design of the cooling water circuit during the rotation of the inner cylinder, reduces the difficulty of rotation sealing and leakage risk, and improves the reliability and stability of the water circuit connection. (2) The drive shaft simultaneously undertakes the dual functions of driving the inner cylinder to rotate and conveying cooling water, realizing the structural integration of power transmission and fluid conveying, reducing the number of parts, simplifying the overall structure, and reducing manufacturing costs and assembly complexity. (3) A complete and closed cooling water flow path is formed, which can realize the supply and discharge of cooling water, ensure the renewal of cooling water in the cooling water chamber, and improve the drying or condensation efficiency of clothing processing equipment.

[0032] Specifically, the cooling water channel 315 includes a first cooling water channel 3151 and a second cooling water channel 3152. The first cooling water channel 3151 is disposed inside the cooling water chamber 242, and the second cooling water channel 3152 is disposed outside the cooling water chamber 242 and away from the heat exchange chamber 241. The first cooling water channel 3151 extends radially along the drive shaft 31 and there are multiple first cooling water channels 3151, which are spaced apart circumferentially along the drive shaft 31. The second cooling water channel 3152 extends axially along the drive shaft 31. The first shaft end 311 is provided with a first shaft water inlet 313 at a position corresponding to each first cooling water channel 3151, that is, one end of each first cooling water channel 3151 is connected to the corresponding first shaft water inlet 313, and the other end of each first cooling water channel 3151 is connected to one end of the second cooling water channel 3152. The other end of the second cooling water channel 3152 is connected to the second shaft water inlet 314. A sealing ring 35 is provided between the cooling water pipe 321 and the second shaft water inlet 314 to prevent cooling water from being discharged through the gap between the cooling water pipe 321 and the second shaft water inlet 314.

[0033] The following further explains how cooling water is input into or discharged from the cooling water chamber 242 via the water pump 33. The water pump 33 includes a water pump inlet, a water pump outlet, and a water pump outlet. The water pump outlet and the second shaft outlet 314 are connected through the cooling water pipe 321. The inner cylinder assembly also includes a water pump inlet pipe 322 and a water pump drain pipe 323. One end of the water pump inlet pipe 322 is connected to the water pump inlet, and an inlet valve 341 is connected in series with the water pump inlet pipe 322. One end of the water pump drain pipe 323 is connected to the water pump drain outlet, and a drain valve 342 is connected in series with the water pump drain pipe 323. Both the inlet valve 341 and the drain valve 342 can be controlled to open and close. When the inlet valve 341 is open and the drain valve 342 is closed, the water pump inlet pipe 322 is connected to the cooling water flow path. By controlling the water pump 33 to run in either forward or reverse rotation, the cooling water inlet 232 can input new cooling water into the cooling water chamber 242. When the inlet valve 341 is closed and the drain valve 342 is open, the water pump drain pipe 323 is connected to the cooling water flow path. By controlling the water pump 33 to run in either forward or reverse direction, the old cooling water in the cooling water port 232 can be discharged from the cooling water chamber 242.

[0034] To address the issue of low heat exchange efficiency in the heat exchange chamber 241, this embodiment proposes that the heat exchange chamber 241 has guide ribs on its cavity wall near the cooling water chamber 242 to guide the condensate formed by the airflow condensation.

[0035] like Figure 9 As shown, the first configuration of the heat exchange chamber 241 and the cooling water chamber 242 will be described below. An inner plate 211 is provided inside the inner cylinder 1 and near the bottom 13 of the inner cylinder. The inner plate 211, the bottom 13 of the inner cylinder, and the peripheral wall 11 of the inner cylinder together form the heat exchange chamber 241. The inner plate 211 is provided with an air inlet 231 for the heat exchange chamber. The portion of the peripheral wall 11 of the inner cylinder that forms the heat exchange chamber 241 has a flow port 111. An outer shell 212 is provided outside the inner cylinder 1 and near the bottom 13 of the inner cylinder. The outer shell 212 and the bottom 13 of the inner cylinder together form the cooling water chamber 242. The end wall of the outer shell 212 away from the bottom 13 of the inner cylinder is provided with a cooling water outlet 232. The heat exchange chamber 241 and the cooling water chamber 242 are separated by the bottom 13 of the inner cylinder, and the airflow in the heat exchange chamber 241 and the cooling water in the cooling water chamber 242 exchange heat through the bottom 13 of the inner cylinder.

[0036] In this way, the following technical effects can be achieved: (1) By setting an inner plate inside the inner cylinder, the bottom wall and peripheral wall of the inner cylinder itself are directly used as the surrounding wall of the heat exchange cavity, which simplifies the number of parts and reduces the manufacturing cost; the flow port is set at the corresponding part of the peripheral wall of the inner cylinder, so that the airflow and condensate after heat exchange and cooling in the heat exchange cavity can be discharged from the peripheral wall of the inner cylinder in a timely manner, ensuring smooth airflow and timely discharge of condensate in the heat exchange cavity, and maintaining the continuous and stable operation of the heat exchange process. (2) By setting an outer shell outside the inner cylinder, the bottom of the inner cylinder is directly used as one side wall of the cooling water chamber, which simplifies the structural design; the inlet and outlet directions of the cooling water are consistent with the axial direction of the inner cylinder, which facilitates the introduction and discharge of the cooling water; by using the bottom of the inner cylinder as a shared partition wall for the heat exchange chamber and the cooling water chamber, the two chambers are spatially isolated, ensuring that the airflow and the cooling water can be efficiently heat-conducted through the bottom of the inner cylinder. (3) No additional heat exchanger or heat exchange pipeline is required. The large area of ​​the metal wall at the bottom of the inner cylinder is used as the heat exchange surface, resulting in a large heat exchange area and high heat exchange efficiency.

[0037] <Clothing Processing Equipment> like Figures 5 to 7 As shown, this embodiment provides a garment processing device, including an outer cylinder 4 and an inner cylinder assembly as described in any of the above claims; the outer cylinder 4 is provided with an outer cylinder air outlet and an outer cylinder drain outlet 42, and the inner cylinder 1 is rotatably disposed inside the outer cylinder 4; multiple flow ports 111 are provided, and the multiple flow ports 111 include a heat exchange chamber air outlet and a heat exchange chamber drain outlet; The airflow discharged through the heat exchange chamber outlet enters the outer cylinder 4 and then exits the outer cylinder 4 through the outer cylinder outlet; the condensate discharged through the heat exchange chamber drain outlet enters the outer cylinder 4 and then exits the outer cylinder 4 through the outer cylinder drain outlet 42.

[0038] Furthermore, the garment processing equipment also includes a condensing air duct 51, a fan 52, and a heating air duct 53, all of which are located outside the outer cylinder 4; the inner cylinder 1, the heat exchange chamber air inlet 231, the heat exchange chamber 241, the heat exchange chamber air outlet, the outer cylinder 4, the outer cylinder air outlet, the condensing air duct 51, the fan 52, and the heating air duct 53 are sequentially connected to form a drying circuit; The heat exchange chamber 241 is used for primary dehumidification of the airflow, and the condenser duct 51 is used for secondary dehumidification of the airflow. The fan 52 is used to circulate the airflow in the drying circuit. The heating duct 53 is equipped with a heating element 54, which is used to heat the airflow flowing through the heating duct 53.

[0039] Specifically, the outer cylinder 4 includes an outer cylinder peripheral wall, with an outer cylinder opening at one axial end and an outer cylinder bottom at the other axial end; a shaft hole is provided at the center of the outer cylinder bottom, and a drive shaft 31 passes through the shaft hole, with a bearing provided between the drive shaft 31 and the hole wall; the outer cylinder air outlet includes an upper outer cylinder air outlet and a lower outer cylinder air outlet arranged opposite each other; the condensing air duct 51 is provided with an upper condensing air inlet, a lower condensing air inlet, and a condensing air outlet, with the upper condensing air inlet and the upper outer cylinder air outlet correspondingly arranged and connected, and the lower condensing air inlet and the lower outer cylinder air inlet correspondingly arranged and connected; the condensing air outlet is connected to the fan; When the fan is running, the airflow in the inner cylinder 1 enters the heat exchange chamber 241 through the heat exchange chamber inlet 231 (the airflow in the heat exchange chamber 241 and the cooling water in the cooling water chamber 242 exchange heat through the cavity wall between the heat exchange chamber 241 and the cooling water chamber 242, thereby dehumidifying the airflow), and then is discharged to the outer cylinder 4 through the heat exchange chamber outlet; part of the airflow in the outer cylinder 4 enters the condenser duct 51 through the outer cylinder upper outlet and the condenser upper inlet, and part of the airflow enters the condenser duct 51 through the outer cylinder lower outlet and the condenser lower inlet; the airflow in the condenser duct 51 enters the fan through the condenser outlet, and then enters the inner cylinder through the heating duct 53; this cycle is repeated to dry the clothes in the inner cylinder 1.

[0040] <Control Methods> like Figure 8 As shown, this embodiment provides a control method for a garment processing device, wherein the garment processing device is any of the garment processing devices described above, and the drying process of the garment processing device includes a drying preparation stage, a drying stage, and a drying judgment stage; the control method includes: S1. When the clothing processing equipment is in the drying preparation stage, control the water pump 33 to run, so that the cooling water inlet 232 inputs cooling water into the cooling water chamber 242 until the water level of the cooling water in the cooling water chamber 242 reaches the preset water level. S2. When the garment processing equipment is in the drying stage and / or the judging stage, the temperature inside the inner drum 1 and the temperature of the cooling water in the cooling water chamber 242 are obtained. S3. Based on the temperature inside the inner cylinder 1 and the temperature of the cooling water in the cooling water chamber 242, determine whether the cooling water in the cooling water chamber 242 needs to be replaced. S4. Based on the judgment result of whether the cooling water in the cooling water chamber 242 needs to be updated, control the water pump 33 to run or keep it stopped. The temperature inside the inner cylinder 1 is the temperature of the clothes inside the inner cylinder 1 or the temperature of the airflow; the preset water level is greater than the water level at 2 / 3 of the volume of the cooling water chamber 242 and less than or equal to the water level of the volume of the cooling water chamber 242.

[0041] Furthermore, S3 includes: S31. Calculate the temperature difference between the temperature inside the inner cylinder 1 and the temperature of the cooling water in the cooling water chamber 242; S32. Compare the temperature difference with the preset temperature, and the duration of the temperature difference with the preset duration; S33. Based on the comparison between the temperature difference and the preset temperature, and / or the comparison between the duration of the temperature difference and the preset duration, determine whether it is necessary to update the cooling water in the cooling water chamber 242.

[0042] The following further explains step S33, where the preset temperature includes a first preset temperature and a second preset temperature; S33 includes: When the temperature difference is greater than the first preset temperature, it is determined that the cooling water in the cooling water chamber 242 does not need to be updated. When the temperature difference is less than the second preset temperature and the duration of the temperature difference is greater than the preset duration, it is determined that the cooling water in the cooling water chamber 242 needs to be updated. The first preset temperature is greater than the second preset temperature. The first preset temperature is 8℃, the second preset temperature is 3℃, and the preset duration is 30 seconds.

[0043] The following provides a further explanation of step S4, which includes: S41. When it is determined that the cooling water in the cooling water chamber 242 does not need to be updated, control the water pump 33 to remain stopped. S42. When it is determined that the cooling water in the cooling water chamber 242 needs to be updated, obtain the current weight of the clothing inside the inner cylinder 1. S43. Determine the target flow rate of cooling water based on the current weight, and control water pump 33 to operate according to the target flow rate.

[0044] In this way, the following technical effects can be achieved: (1) When the temperature difference between the heat exchange chamber and the cooling water chamber is large enough, the water pump is actively controlled not to start, so as to avoid unnecessary cooling water supply and discharge, thereby saving water resources and reducing the energy consumption of the water pump. (2) After determining that the cooling water needs to be updated, the key parameter of clothing weight is obtained first to provide a data basis for the precise adjustment of cooling water flow rate. The correspondence between clothing weight and target cooling water flow rate is established. The heavier the load, the larger the target flow rate; the lighter the load, the smaller the target flow rate. This realizes the dynamic matching of cooling water supply and actual heat exchange demand, and minimizes cooling water consumption while ensuring condensation effect. (3) By controlling the water pump to operate at a determined target flow rate, the cooling water in the cooling water chamber is continuously updated at a suitable flow rate, ensuring that the cooling water is always maintained within a temperature range with sufficient heat exchange capacity, thereby ensuring that the heat exchange between the heat exchange chamber and the cooling water chamber is carried out continuously and efficiently, and improving the drying or condensation efficiency of the clothing processing equipment.

[0045] Furthermore, S43 includes: Compare the current weight with the preset weight; The target flow rate of cooling water is determined based on the comparison between the current weight and the preset weight. Control water pump 33 to first discharge cooling water at the target flow rate, and then input cooling water at the target flow rate.

[0046] Specifically, the preset weight is 5kg. When the current weight is less than or equal to the preset weight, the clothes in the inner drum are lightly loaded; when the current weight is greater than the preset weight, the clothes in the inner drum are heavily loaded. When the inner drum is lightly loaded with clothes, the target flow rate is 30% of the volume of cooling water chamber 242; when the inner drum is heavily loaded with clothes, the target flow rate is greater than 60% of the volume of cooling water chamber 242. Alternatively, if the current weight is less than 3kg, the clothes in the inner drum are lightly loaded; if the current weight is greater than or equal to 3kg and less than or equal to 6kg, the clothes in the inner drum are medium loaded; if the current weight is greater than 6kg, the clothes in the inner drum are heavy loaded. When the clothes inside the inner drum are lightly loaded, the target flow rate is 30% of the volume of the cooling water chamber 242; when the clothes inside the inner drum are medium loaded, the target flow rate is 45% of the volume of the cooling water chamber 242; when the clothes inside the inner drum are heavy loaded, the target flow rate is 60% of the volume of the cooling water chamber 242.

[0047] Example 2 like Figure 10 As shown, unlike the formation of heat exchange chamber 241 and cooling water chamber 242 in Embodiment 1, this embodiment proposes a second formation of heat exchange chamber 241 and cooling water chamber 242. A first partition 251 and a second partition 252 are provided inside the inner cylinder 1 and near the bottom 13 of the inner cylinder. The first partition 251 and the second partition 252 are spaced apart along the axial direction of the inner cylinder 1, and the second partition 252 is closer to the bottom 13 of the inner cylinder than the first partition 251. The first partition 251, the second partition 252, and the inner cylinder peripheral wall 11... The heat exchange chamber 241 is formed by the two partitions. The first partition 251 is provided with an air inlet 231 for the heat exchange chamber. The part of the inner cylinder peripheral wall 11 that forms the heat exchange chamber 241 has a flow outlet 111. The second partition 252, the bottom of the inner cylinder 13 and the inner cylinder peripheral wall 11 together form a cooling water chamber 242. The bottom of the inner cylinder 13 is provided with a cooling water outlet 232. The heat exchange chamber 241 and the cooling water chamber 242 are separated by the second partition 252, and the airflow in the heat exchange chamber 241 and the cooling water in the cooling water chamber 242 exchange heat through the second partition 252.

[0048] In this way, the following technical effects can be achieved: By setting a first baffle and a second baffle inside the inner cylinder, the bottom area of ​​the inner cylinder is divided into a heat exchange chamber and a cooling water chamber in the axial direction, and the second baffle is used as a common heat-conducting baffle between the two chambers. On the basis of realizing the heat exchange function, it further achieves the following: the two chambers are directly formed by the internal components of the inner cylinder, without the need for an independent shell, resulting in fewer parts and lower cost; the two chambers are arranged axially adjacent inside the inner cylinder, without occupying the external space of the inner cylinder; and the large-area metal wall surface of the second baffle is used as the heat exchange surface, resulting in a short heat conduction path and high heat exchange efficiency.

[0049] Example 3 like Figure 11 As shown, unlike the formation of heat exchange cavity 241 and cooling water cavity 242 in Embodiment 1, this embodiment proposes a third formation of heat exchange cavity 241 and cooling water cavity 242. An outer shell 212 is provided outside the inner cylinder 1 and near the bottom 13 of the inner cylinder. An outer plate 26 is provided inside the outer shell 212. The bottom 13 of the inner cylinder, the outer plate 26 and a part of the peripheral wall of the outer shell 212 together form heat exchange cavity 241. The bottom 13 of the inner cylinder is provided with heat exchange cavity air inlet 231. The part of the peripheral wall of the outer shell 212 that forms heat exchange cavity 241 forms flow port 111. The outer plate 26, another part of the peripheral wall of the outer shell 212 and the end wall of the outer shell 212 away from the bottom 13 of the inner cylinder together form cooling water cavity 242. The end wall of the outer shell 212 away from the bottom 13 of the inner cylinder is provided with cooling water port 232.

[0050] In this way, the following technical effects can be achieved: By installing an outer shell with an outer plate outside the inner cylinder, both the heat exchange chamber and the cooling water chamber are arranged outside the inner cylinder, and the outer plate is used as a shared heat-conducting baffle between the two chambers. In addition to achieving the heat exchange function, the design further achieves the following: both chambers are located outside the inner cylinder, without encroaching on the effective clothing handling volume of the inner cylinder; the air inlet of the heat exchange chamber is located on the bottom of the inner cylinder, allowing the hot and humid airflow inside the inner cylinder to directly enter the heat exchange chamber through the bottom of the inner cylinder, resulting in a very short airflow path and minimal heat loss; the heat exchange chamber and the cooling water chamber are arranged axially adjacent inside the outer shell, resulting in a compact overall structure; and the large-area metal wall surface of the outer plate serves as the heat exchange surface, leading to high heat exchange efficiency.

[0051] Example 4 like Figure 12 As shown, unlike the formation of heat exchange cavity 241 and cooling water cavity 242 in Embodiment 1, this embodiment proposes a fourth formation of heat exchange cavity 241 and cooling water cavity 242. A first shell 221 and a second shell 222 are provided outside the inner cylinder 1 and near the bottom 13 of the inner cylinder. The first shell 221 and the second shell 222 are spaced apart along the axial direction of the inner cylinder 1, and the first shell 221 is closer to the bottom 13 of the inner cylinder than the second shell 222. The first shell 221 surrounds the heat exchange cavity 241. The bottom 13 of the inner cylinder is provided with an air outlet of the inner cylinder. The end wall of the first shell 221 near the bottom 13 of the inner cylinder is provided with an air inlet 231 of the heat exchange cavity. A flow port 111 is formed on the peripheral wall of the first shell 221. The air outlet of the inner cylinder and the air inlet 231 of the heat exchange cavity are connected. The second shell 222 surrounds the cooling water cavity 242. The end wall of the second shell 222 away from the bottom 13 of the inner cylinder is provided with a cooling water inlet 232.

[0052] In this way, the following technical effects can be achieved: By setting independent first and second shells outside the inner cylinder, forming a heat exchange chamber and a cooling water chamber respectively, with the two shells spaced apart along the axial direction, the system achieves the following: both shells are located outside the inner cylinder, without encroaching on the effective clothing handling volume of the inner cylinder; the heat exchange chamber and cooling water chamber each have complete independent shells, are structurally completely separated, do not interfere with each other, and have good sealing performance; there is no shared wall between the two chambers, avoiding heat conduction in unexpected directions through the shared wall, resulting in more precise temperature control; and the two shells are independent of each other, facilitating separate inspection and maintenance.

[0053] Example 5 Unlike step S4 in Example 1, step S4 in this example includes: S41. When it is determined that the cooling water in the cooling water chamber 242 does not need to be updated, control the water pump 33 to remain stopped. S42. When it is determined that the cooling water in the cooling water chamber 242 needs to be updated, obtain the current weight of the clothing inside the inner cylinder 1. S43. Determine the target flow rate of cooling water based on the current weight, temperature difference and second preset temperature, and control the water pump 33 to operate according to the target flow rate.

[0054] Thus, after determining that the cooling water needs to be updated, the two key parameters of clothing weight and temperature difference are obtained first, providing a data basis for the precise adjustment of the cooling water flow rate. A correspondence between clothing weight, temperature difference, second preset temperature and target cooling water flow rate is established. The heavier the load and the greater the temperature difference and the difference between the second preset temperature, the larger the target flow rate; the lighter the load and the smaller the temperature difference and the difference between the second preset temperature, the smaller the target flow rate. This achieves dynamic matching between the cooling water supply and the actual heat exchange demand, minimizing cooling water consumption while ensuring condensation effect.

[0055] Furthermore, S43 includes: Compare the current weight with the preset weight and temperature difference, and the second preset temperature; The target flow rate of cooling water is determined based on the comparison between the current weight and the preset weight, the temperature difference, and the comparison with the second preset temperature. Control water pump 33 to first discharge cooling water at the target flow rate, and then input cooling water at the target flow rate.

[0056] Specifically, the preset weight is 5kg. When the current weight is less than or equal to the preset weight, the clothes in the inner drum are lightly loaded; when the current weight is greater than the preset weight, the clothes in the inner drum are heavily loaded. When the clothes inside the inner drum are lightly loaded and the temperature difference is slightly lower than the second preset temperature, the target flow rate is 20%-30% of the volume of the cooling water chamber 242. When the clothes inside the inner drum are heavily loaded and the temperature difference is much lower than the second preset temperature, the target flow rate is greater than 50% of the volume of the cooling water chamber 242.
