Description

Technical Field

[0001] This invention belongs to the field of clothing care, specifically, it relates to a dehumidification module and a washing and care device. Background Technology

[0002] Currently, most laundry and garment care equipment uses a hot air circulation system to care for clothes, achieving functions such as drying and deodorizing. A hot air circulation system generally includes an air duct, a fan, and a dehumidifying and heating device installed within the duct. Air enters the duct through the return air inlet under the action of the fan, is dehumidified and heated by the dehumidifying and heating device, and then is exhausted back into the cabinet of the laundry and garment care equipment through the air outlet for further dehumidification.

[0003] In existing technologies, dehumidification and heating devices in hot air circulation systems typically use heat exchange to dehumidify and heat humid air. However, when the air volume in the duct is large, the dehumidification and heating effect is greatly reduced, thus affecting the dehumidification effect, leading to mold growth in the washing and care equipment and causing items to have an odor. Moreover, there are problems such as long drying time and high cost, especially in the later stages of drying, when the air volume in the drying channel is large but the water vapor concentration is low, requiring a long drying time.

[0004] Moreover, existing hot air circulation systems are bulky, occupying a large space within the washing and care equipment, and have high production costs. The motor does not directly drive the hot air circulation system, which can easily damage the impeller in the hot air circulation system. Furthermore, the connections are complex and the control effect is poor.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art. The purpose is to provide a dehumidification module in which a rotating wheel is rotatably arranged inside a receiving cavity. After the rotating wheel adsorbs moisture in the receiving cavity in the adsorption zone, it rotates to the desorption zone to detach and is discharged through the regeneration channel, thereby improving the dehumidification efficiency of the dehumidification module. Furthermore, the dehumidification module of this invention has a simple structure, compact internal space, and low production cost. The rotating wheel is directly driven by a motor, which prevents the rotating wheel from being damaged by force, improves the service life of the rotating wheel, and solves the problems of rotating wheel damage and deformation under force.

[0007] Another object of the present invention is to provide a washing and care device.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a dehumidification module, comprising:

[0009] The housing has an internal cavity, an air inlet for introducing external moisture into the cavity, and an air outlet for discharging dry air.

[0010] The rotating wheel is rotatably disposed in the receiving cavity and supported on the housing by a rotating shaft. The receiving cavity includes an adsorption zone and a desorption zone. The rotating wheel has a position that reciprocates between the adsorption zone and the desorption zone. After adsorbing moisture in the receiving cavity in the adsorption zone, the rotating wheel rotates to the desorption zone to detach.

[0011] An electric motor, which is connected to the rotating shaft, is used to drive the rotating wheel to rotate within the receiving cavity.

[0012] Furthermore, the air inlet is located on one side wall of the housing, the motor is located outside the other side wall of the housing, one end of the rotating shaft is connected to the rotating wheel, and the other end passes through the other side wall of the housing and is connected to the output end of the motor.

[0013] Furthermore, the air inlet is disposed on the side wall of the housing opposite to the wheel surface of the rotor, and the motor is disposed on the other side wall of the housing opposite to the air inlet;

[0014] The air outlet is located on the outer peripheral wall of the housing in the circumferential direction of the rotor, and the air inlet and air outlet are located on the same side as the wheel surface of the rotor.

[0015] Furthermore, the receiving cavity includes a first receiving portion and a second receiving portion connected in sequence, wherein the inner diameter of the first receiving portion is smaller than the inner diameter of the second receiving portion;

[0016] The rotating wheel is rotatably disposed within the first receiving portion, and the motor is disposed on the outer side wall of the first receiving portion and is connected to the rotating shaft for transmission.

[0017] Furthermore, the dehumidification module also includes a regeneration channel for discharging the moisture from the desorption zone outside the housing;

[0018] The regeneration channel is located in the receiving cavity on the side opposite to the motor, within the second receiving part. The air inlet at one end of the regeneration channel is located near the wheel surface of the desorption zone, and is used to extract moisture from the desorption zone.

[0019] Alternatively, the regeneration channel is located at an opening, with one end positioned close to the wheel surface of the rotor, and the other end extending through the opening to the outside of the housing, for discharging the desorbed moisture outside the housing.

[0020] Furthermore, the air outlet of the regeneration channel is located on the side wall between the first receiving portion and the second receiving portion.

[0021] A heating unit is provided at the air inlet of the regeneration channel for heating the desorption zone;

[0022] A dehumidifier is installed at the air outlet to extract and discharge moisture from the regeneration channel.

[0023] Furthermore, the rotating wheel is provided with a connecting part located on the side of the rotating wheel near the other side wall of the housing, for fixing the rotating shaft;

[0024] One end of the rotating shaft is provided with a mounting part, which is connected to the connecting part, and a bearing is provided on the other side wall of the housing opposite to the connecting part;

[0025] One end of the rotating shaft is fixed to the connecting part of the wheel via the mounting part, and the other end passes through the bearing to the outside of the housing for connection of the output shaft of the motor.

[0026] Furthermore, the motor includes,

[0027] The inner stator is fixed on one side to the outer wall of the second receiving part;

[0028] The outer rotor is sleeved on the outer periphery of the other side of the inner stator and connected to the other end of the rotating shaft to drive the rotating shaft to rotate.

[0029] Furthermore, the outer rotor is splinedly connected to the other end of the rotating shaft.

[0030] A washing and care device that employs any of the dehumidification modules described above.

[0031] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] (1) The present invention rotatably sets the rotating wheel inside the housing, adsorbs the moisture in the containment cavity in the adsorption zone, rotates the wheel to the desorption zone, detaches in the desorption zone, and discharges through the regeneration channel. By setting the adsorption zone and desorption zone in the dehumidification module, the adsorption zone adsorbs the moisture in the containment cavity, the desorption zone receives the moisture absorbed by the adsorption zone, and discharges through the air outlet of the regeneration channel, it can concentrate the gas with a large air volume and low concentration of water vapor into the gas with a small air volume and high concentration of water vapor, thereby improving the dehumidification efficiency of the dehumidification module. In addition, the dehumidification module of the present invention has a simple structure, compact internal space, and low production cost.

[0033] (2) This invention connects the motor directly to the rotating shaft, allowing the motor to directly drive the rotating wheel to rotate. This prevents the rotating wheel from being damaged by stress, increases its service life, and solves problems such as damage and deformation of the rotating wheel due to stress. At the same time, it reduces the space occupied by the dehumidification module, reduces the complexity of the motor driving the rotating wheel, and improves the control effect of the rotating wheel.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] like Figures 1 to 2 As shown, the dehumidification module of the present invention includes a housing 1 and a rotating wheel 2.

[0044] The housing 1 has an internal cavity 11 and an air inlet 12 for introducing external moisture into the cavity 11. The housing 1 also has an air outlet 13 for discharging dry air.

[0045] The rotating wheel 2 is rotatably disposed in the receiving cavity 11 and supported on the housing 1 by a rotating shaft 21. The receiving cavity 11 includes an adsorption zone 111 and a desorption zone 112. The rotating wheel 2 has a position that reciprocates between the adsorption zone 111 and the desorption zone 112. After adsorbing moisture in the receiving cavity 11 in the adsorption zone 111, the rotating wheel 2 rotates to the desorption zone 112 to detach.

[0046] The dehumidification module also includes a motor 5.

[0047] The motor 5 is connected to the rotating shaft 21 for driving the wheel 2 to rotate within the receiving cavity 11.

[0048] This application uses a motor 5 mounted on the housing 1 and directly connected to the rotating shaft 21 for transmission. The motor 5 directly drives the rotating wheel 2 to rotate within the receiving cavity 11, preventing the rotating wheel 2 from being damaged by force. At the same time, it facilitates the control of the rotating wheel 2 during operation, improves the service life of the rotating wheel 2, and solves problems such as damage and deformation of the rotating wheel 2 under force.

[0049] Furthermore, the air inlet 12 is disposed on one side wall of the housing 1, the motor 5 is disposed on the other side wall of the housing 1 opposite to the air inlet 12, and the rotating wheel 2 is supported on the other side wall of the housing 1 by the rotating shaft 21.

[0050] Furthermore, the dehumidification module also includes a regeneration channel 4, one end of which is an air inlet 43 for receiving moisture in the desorption zone 112; the other end of the regeneration channel 4 is an air outlet 44 for discharging moisture out of the housing 1.

[0051] This invention rotatably mounts a rotating wheel 2 inside the housing 1 and supports it on the housing 1 via a rotating shaft 21. After adsorbing moisture in the receiving cavity 11 in the adsorption zone 111, the rotating wheel 2 rotates to the desorption zone 112 to disengage and is discharged through the regeneration channel 4. By setting an adsorption zone 111 and a desorption zone 112 in the dehumidification module, the adsorption zone 111 adsorbs moisture in the receiving cavity 11, and the desorption zone 112 receives the moisture absorbed by the adsorption zone 111 and discharges it through the outlet 44 of the regeneration channel 4. This can concentrate a large volume of low-concentration water vapor into a small volume of high-concentration water vapor, improving the dehumidification efficiency of the dehumidification module. Furthermore, the dehumidification module of this invention has a simple structure, compact internal space, and low production cost.

[0052] It should be noted that the concentration of moisture desorbed from desorption zone 112 can be N times the concentration of moisture entering adsorption zone 111. Where 1 < N < 200.

[0053] The impeller 2 is made of a material that can absorb moisture at low temperatures and dehumidify at high temperatures.

[0054] The rotor 2 has a large specific surface area, various pore structures and pore size distributions, and rich surface properties, and has a strong adsorption capacity for water vapor.

[0055] In one specific embodiment, the receiving cavity 11 is provided with an adsorption region 111 and a desorption region 112 in sequence along the circumference to form a plurality of fan-shaped regions, wherein the angle of the fan-shaped region where the adsorption region 111 is located is greater than the angle of the fan-shaped region where the desorption region 112 is located.

[0056] The positions of the adsorption zone 111 and the desorption zone 112 remain fixed, and the rotating wheel 2 rotates at a certain speed. The speed of the rotating wheel 2 is 0.01-60 r / min. Preferably, the speed of the rotating wheel 2 is 0.02-10 r / min.

[0057] Preferably, the angle of the adsorption region 111 is an acute angle, and the angle of the desorption region 112 is an acute angle.

[0058] The rotor 2 is at least partially made of a low-temperature moisture-absorbing and high-temperature moisture-removing material, and has a porous structure. The porous structure of the rotor 2 is arranged opposite to the adsorption zone 111 and the desorption zone 112.

[0059] Furthermore, the rotating wheel 2 is a zeolite rotating wheel 2, a silica gel rotating wheel 2, a graphene rotating wheel 2, or an activated alumina rotating wheel 2.

[0060] Zeolite Rotor 2 (zeolite AmBpO2p·nH2O) Zeolite is an aluminosilicate mineral containing alkali metals or alkaline earth metals. Its crystal structure is typically composed of silicon-oxygen tetrahedra and aluminum-oxygen tetrahedra linked together to form a framework nanocrystalline structure, creating cavities of different shapes and sizes. This allows for the selective adsorption and filtration of nonpolar / polar molecules smaller than the pore size. When humidity is high, zeolite can absorb moisture through its numerous tiny pores; when the environment is dry, it can release moisture to maintain humidity. Furthermore, as the ambient humidity changes, the temperature will naturally adjust accordingly.

[0061] Silicone roller 2 (silicone (mSiO2·nH2O), also known as silica gel).

[0062] Activated alumina rotor 2 (activated alumina, with the chemical formula Al2O3).

[0063] All of the impellers 2 have the characteristics of low-temperature moisture absorption and high-temperature dehumidification.

[0064] Furthermore, the air inlet 12 is disposed on one side wall of the housing 1, the motor 5 is disposed outside the other side wall of the housing 1, one end of the rotating shaft 21 is connected to the rotating wheel 2, and the other end passes through the other side wall of the housing 1 and is connected to the output end of the motor 5.

[0065] This application improves the control effect of the rotating wheel 2 and increases working efficiency by setting the motor 5 outside the other side wall of the housing 1 and directly controlling the rotation of the rotating wheel 2 through the rotating shaft 21. This avoids the motor 5 being set inside the housing cavity 11, which would cause pollution to the housing cavity 11 during operation, and prevents moisture from entering the interior of the motor 5 and causing damage to the motor 5. Setting it outside the housing cavity 11 makes it convenient to replace and maintain the motor 5.

[0066] Furthermore, the air inlet 12 is disposed on the side wall of the housing 1 opposite to the wheel surface of the rotating wheel 2, and the motor 5 is disposed on the other side wall of the housing 1 opposite to the air inlet 12.

[0067] The air outlet 13 is disposed on the outer peripheral wall of the housing 1 on the circumferential direction of the rotating wheel 2, and the air inlet 12 and the air outlet 13 are located on the same side as the wheel surface of the rotating wheel 2.

[0068] By setting the air inlet 12 on the side wall of the housing 1 opposite to the wheel surface of the rotor 2 and communicating with the receiving cavity 11, it is convenient for moisture to directly contact the adsorption zone 111 in the receiving cavity 11 when air is introduced, thereby improving the adsorption characteristics of the adsorption zone 111. At the same time, the air outlet 13 is set on the outer peripheral wall of the housing 1 around the rotor 2. The air inlet 12 and the air outlet 13 are located on the same side as the wheel surface of the rotor 2, which makes it convenient for the dehumidified dry air to be directly discharged through the air outlet 13.

[0069] Specifically, after the moisture enters the receiving cavity 11 through the air inlet 12, it is adsorbed by the adsorption zone 111 in the receiving cavity 11. Then, the dehumidified moisture is discharged through the air outlet 13. The moisture adsorbed on the adsorption zone 111 is rotated by the motor 5 to the desorption zone 112 to be desorbed. The desorbed moisture is then discharged through the air inlet 43 and the air outlet 44 of the regeneration channel 4.

[0070] Furthermore, the receiving cavity 11 includes a first receiving portion 113 and a second receiving portion 114, wherein the inner diameter of the first receiving portion 113 is smaller than the inner diameter of the second receiving portion 114.

[0071] The rotating wheel 2 is rotatably disposed within the first receiving portion 113; the motor 5 is disposed on the outer side wall of the first receiving portion 113 and is connected to the rotating shaft 21 for transmission.

[0072] The regeneration channel 4 is disposed inside the second receiving part 114, the air inlet 12 is disposed on the side wall of the housing 1 where the second receiving part 114 is located, and the air outlet 13 is disposed on the outer peripheral wall of the housing 1 where the second receiving part 114 is located.

[0073] The present invention rotatably arranges the rotating wheel 2 in the first receiving part 113, arranges the regeneration channel 4 in the second receiving part 114, arranges the air inlet 12 on the side wall of the housing 1 where the second receiving part 114 is located, and arranges the air outlet 13 on the outer peripheral wall of the housing 1 where the second receiving part 114 is located, so that the air entering the receiving cavity 11 flows on the surface of the rotating wheel 2, ensuring the high efficiency of the rotating wheel 2 in absorbing moisture.

[0074] At the same time, air only passes through the surface of the rotor 2 and does not penetrate the rotor 2 to enter the gap inside the rotor 2, thus preventing the air-carried lint from clogging the gap inside the rotor 2 and causing damage to the rotor 2.

[0075] Meanwhile, the motor 5 is located on the outer wall of the first receiving part 113 and is connected to the rotating shaft 21 for transmission, which reduces the distance between the motor 4 and the rotating wheel 2, improves the compactness of the dehumidification module, and reduces the space occupied by the dehumidification module during installation.

[0076] In one embodiment, the regeneration channel 4 is disposed in the receiving cavity 11 on the opposite side of the motor 5, located in the second receiving part 114, and the air inlet 43 at one end of the regeneration channel 4 is disposed near the wheel surface of the desorption zone 112 for extracting moisture from the desorption zone 112.

[0077] The air inlet 43 of the regeneration channel 4 is positioned close to the wheel surface of the rotor 2 in the desorption zone 112, so that the gas with a small air volume and high concentration of water vapor in the desorption zone 112 is completely discharged through the regeneration channel 4. This avoids the gas with a small air volume and high concentration of water vapor in the desorption zone 112 remaining in the shell 1, which would result in poor dehumidification effect and long drying time for the rotor 2.

[0078] In another embodiment, the regeneration channel 4 is located at an opening, with one end close to the wheel surface of the rotor 2, and the other end extending through the opening to the outside of the housing 1, for discharging the desorbed moisture outside the housing 1.

[0079] In this embodiment, moisture is introduced into the housing 1 through an opening. The opening serves the same function as the air inlet 12, allowing for rapid dehumidification due to the large air intake. The rotating wheel 2 is rotatably installed in the housing 1. After adsorbing moisture in the adsorption zone 111, it discharges dry air through the air outlet 13. The regeneration channel 4 discharges the moisture discharged from the desorption zone 112 to the outside of the housing 1 through the opening, achieving efficient dehumidification. The regeneration channel 4 is located at the opening, which does not occupy much space, making the components of the dehumidification module compact and small in size. It is suitable for household appliance washing and care equipment, and has a simple structure and low cost.

[0080] Furthermore, the air outlet 44 of the regeneration channel 4 is provided on the side wall between the first receiving portion 113 and the second receiving portion 114.

[0081] It should be noted that, since the radius of the second receiving part 114 is larger than the radius of the first receiving part 113, there is a side wall between the second receiving part 114 and the first receiving part 113, and the air outlet 44 of the regeneration channel 4 is disposed on this side wall.

[0082] A circulating fan 3 is installed inside the housing 1 near the air outlet 13 to discharge the adsorbed and dried air.

[0083] The air inlet 43 of the regeneration channel 4 is connected to the desorption zone 112; a heating unit 42 is provided at the air inlet 43, and the heating unit 42 is used to heat the desorption zone 112.

[0084] The present invention provides a heating unit 42 located at the air inlet 43. The heating unit 42 continuously heats the desorption zone 112, keeping the desorption zone 112 at a high temperature. This ensures that the desorption zone 112 can continuously receive the moisture adsorbed in the adsorption zone 111, thereby improving the working efficiency of the desorption zone 112.

[0085] A dehumidifier 41 is provided at the air outlet 44 to extract and discharge the moisture in the regeneration channel 4.

[0086] The present invention provides a dehumidifying fan 41 at the air outlet 44, which allows a small portion of the regenerated air to circulate and discharge the moisture in the desorption zone 112 from the air outlet 44 of the regeneration channel 4, thus avoiding the accumulation of a large amount of moisture inside the dehumidification module.

[0087] Specifically, the regeneration channel 4 is arranged opposite to the air inlet 12.

[0088] Furthermore, the rotating wheel 2 is provided with a connecting part 22, located on the side of the rotating wheel 2 near the other side wall of the housing 1, for fixing the rotating shaft 21.

[0089] One end of the rotating shaft 21 is provided with a mounting part (not shown in the figure), which is connected to the connecting part 22. The other side wall of the housing 1 opposite to the connecting part 22 is provided with a bearing 14.

[0090] One end of the rotating shaft 21 is fixed to the connecting part 22 of the rotating wheel 2 through the mounting part, and the other end passes through the bearing 14 to the outside of the housing 1 for connection of the output shaft (not shown in the figure) of the motor 5.

[0091] This invention provides a connecting part 22 on the rotating wheel 2 and a mounting part at one end of the rotating shaft 21. The rotating shaft 21 is fixedly connected to the rotating wheel 2 via the connecting part 22 and the mounting part. A bearing 14 is provided on the housing 1, opposite to the connecting part 22. This prevents the rotating shaft 21 from damaging the housing 1 during its rotation. At the same time, the other end of the rotating shaft 21 is connected to the output shaft of the motor 5. The motor 5 directly controls the rotation of the rotating wheel 2 via the rotating shaft 21, avoiding stress on the rotating wheel 2 that could lead to breakage or deformation, and increasing the service life of the rotating wheel 2.

[0092] Specifically, the motor 5 includes an inner stator 51 and an outer rotor 52.

[0093] The inner stator 51 is fixed on one side of the outer wall of the first receiving part 113.

[0094] The outer rotor 52 is sleeved on the outer periphery of the other side of the inner stator 51 and connected to the other end of the rotating shaft 21 to drive the rotating shaft 21 to rotate.

[0095] This application fixes the inner stator 51 of the motor 5 to the outer wall of the first receiving part 113 by fixing bolts 54, and sleeves the outer rotor 52 on the outer periphery of the other side of the inner stator 51 and connects it to the other end of the rotating shaft 21. The motor 5 using the outer rotor 52 type is easy to maintain and has good heat dissipation.

[0096] The outer rotor 52 is connected to one end of the rotating shaft 21 via a spline 53. Simultaneously, the outer rotor 52 is fixed to the other end of the rotating shaft 21 by a shaft bolt 55.

[0097] The connecting part 22 of the rotating wheel 2 can be integrally formed with the rotating shaft 21. Alternatively, the connecting part 22 of the rotating wheel 2 can have a plastic middle section, and the mounting part of the rotating shaft 21 and the connecting part 22 of the rotating wheel 2 can be integrally formed by in-mold injection molding. Alternatively, the rotating shaft 21 and the connecting part 22 of the rotating wheel 2 can be fixed together by screws or other structures.

[0098] The present invention also provides a washing and care device 6, which employs any of the dehumidification modules described above.

[0099] like Figure 2 As shown, the washing and care equipment 6 includes a processing chamber 61, a dehumidification chamber 67, a dehumidification channel 62, and a ventilation channel 63. The dehumidification channel 62 includes a first dehumidification channel 621 and a second dehumidification channel 622.

[0100] The first dehumidification channel 621 is connected at one end to the processing chamber 61 and at the other end to the dehumidification chamber 67. The second dehumidification channel 622 is connected at one end to the dehumidification chamber 67 and at the other end to the processing chamber 61.

[0101] Specifically, the other end of the first dehumidification channel 621 is connected to the air inlet 12. One end of the second dehumidification channel 622 is connected to the air outlet 13.

[0102] The ventilation channel 63 is connected to the air outlet 44 of the regeneration channel 4.

[0103] The present invention introduces air from inside the processing chamber 61 into the dehumidification module through the dehumidification channel 62. After being dried by the rotor 2 of the dehumidification module, the dried air is introduced into the processing chamber 61, preventing the interior of the washing and care equipment 6 from becoming damp and breeding odors, bacteria and mold, reducing the investment and operating costs of the washing and care equipment 6, improving the efficiency of moisture removal, and thus improving the drying efficiency of the processing chamber 61.

[0104] A sealing element is provided at the connection between the dehumidification channel 62 and the air inlet 12 and the air outlet 13. A sealing element is also provided at the connection between the ventilation channel 63 and the air outlet 44 of the regeneration channel 4.

[0105] The washing and care equipment 6 also includes a pressure relief channel 66, one end of which is connected to the processing chamber 61, and the other end is connected to the outside of the washing and care equipment 6.

[0106] In addition, a condensation unit 64 is provided on the ventilation channel 63, which is used to condense the moisture discharged from the regeneration channel 4 received by the ventilation channel 63.

[0107] The present invention provides a condensation unit 64 on the ventilation channel 63, which converts the high-concentration water vapor gas discharged from the regeneration channel 4 into condensate and dry gas, and then introduces the dry gas into the processing chamber 61, preventing the problem of dampness inside the washing and care equipment from breeding odors, bacteria and mold; it also shortens the drying time and avoids excessively long drying time.

[0108] Furthermore, the condensation unit 64 is provided with a drain pipe 641 and an exhaust pipe.

[0109] The drainage pipe 641 is used to communicate with the drainage channel of the processing chamber 61.

[0110] The exhaust pipe is used to discharge condensed air.

[0111] By connecting the drainage pipe 641 to the drainage channel of the processing chamber 61 and the exhaust pipe to the processing chamber 61, the gas with a small air volume and high concentration of water vapor is converted into condensate and dry gas, and then the dry air is discharged into the processing chamber 61, which saves resources and avoids directly discharging moisture into the external environment.

[0112] In one specific implementation, the air outlet side of the condensation unit 64 is connected to one end of the exhaust pipe, and the other end of the exhaust pipe is connected to the processing chamber 61.

[0113] Another specific implementation is that the air outlet side of the condensation unit 64 is connected to one end of the exhaust pipe, and the other end of the exhaust pipe is connected to the second dehumidification channel 622.

[0114] It should be noted that the drain pipe 641 can also be directly connected to the drain channel of the dishwasher, so that the condensate water is discharged directly to the outside of the washing and care equipment 6 without passing through the drain channel of the processing chamber 61.

[0115] The dehumidification chamber 67 has a sealed chamber (not shown in the figure), and a partial dynamic seal of the rotor 2 is disposed in the sealed chamber. The desorption zone 112 is disposed in the sealed chamber, and the adsorption zone 111 is disposed outside the sealed chamber. The air inlet of the ventilation channel 63 is connected to the sealed chamber.

[0116] This invention provides a partially dynamic seal for the rotating wheel 2 within the sealed chamber, with the desorption zone 112 located inside the sealed chamber and the adsorption zone 111 located outside the sealed chamber. This allows the moisture in the adsorption zone 111 to be removed by the rotating wheel 2 through the desorption zone 112, and the removed moisture to be sealed within the sealed chamber. This prevents moisture leakage into the processing chamber 61, thus reducing the efficiency of moisture removal and the drying efficiency of the washing and care equipment.

[0117] Furthermore, the washing and care device 6 also includes a housing and a condensate storage box 65, which is disposed inside the housing. The condensate storage box 65 is connected to the drainage channel and the drainage pipe 641 of the processing chamber 61.

[0118] The processing chamber 61, dehumidification channel 62, and ventilation channel 63 are disposed inside the outer casing.

[0119] The present invention provides a condensate storage box 65 inside the outer casing to store the condensate separated by the condensation unit 64, thereby preventing the condensate from being directly discharged to the outside of the outer casing and affecting the external environment.

[0120] The condensate storage box 65 can be used to store the condensate separated by the condensation unit 64 and the water inside the processing chamber 61.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
