[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a clothing processing device and control method. Background Technology

[0002] For clothing processing equipment using water-cooled drying, the drying system includes a condenser duct and a heating duct. The hot and humid drying airflow enters the condenser duct and comes into direct or indirect contact with the condensate water to complete heat exchange, thus transforming into a dry and cool drying airflow. Then, it enters the heating duct through a fan, where it is transformed into a high-temperature and dry drying airflow under the heating action of the heating element. The drying airflow enters the inner drum and exchanges heat with the clothes inside, evaporating the moisture on the surface of the clothes and achieving drying. In the existing technology, the structural design of the condenser required for dehumidifying the drying airflow is unreasonable, resulting in a short heat exchange time and insufficient contact between the drying airflow and the condensate water, leading to low condensation efficiency, incomplete dehumidification, and long drying time, indicating room for further optimization.

[0013] Under the action of the water-blocking component, the condensate discharged through the water outlet of the water storage tank can flow to the inner side of the rear wall of the outer cylinder and flow downward along the inner side of the rear wall of the outer cylinder.

[0014] Further optionally, the drying air outlet is provided with multiple outlets, which are spaced apart in the horizontal direction;

[0015] The condensing air duct includes a main condensing air duct and multiple branch condensing air ducts. The branch condensing air ducts are spaced apart on the outer side of the rear wall of the outer cylinder, and each branch condensing air duct allows condensate to flow through it. The air inlets of the branch condensing air ducts and the drying air outlets are connected one-to-one, and the air outlets of the branch condensing air ducts and the heating air duct are connected through the main condensing air duct; or,

When the drying airflow circulates once in the drying circuit, the drying airflow and condensate can complete the first heat exchange in the condensation zone and the second heat exchange in the condensation duct. This extends the heat exchange time between the drying airflow and condensate, increases the heat exchange area between them, and ensures sufficient contact between the drying airflow and condensate, improving condensation efficiency, thoroughly dehumidifying, and shortening the drying time. This solves the problems of insufficient contact and small heat exchange area between the drying airflow and condensate caused by unreasonable condenser design in existing technologies, and also solves the problems of low condensation efficiency and incomplete dehumidification in existing condensation ducts.

[0040] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0042] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0043] 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.

[0044] In existing clothing processing equipment that uses water-cooled drying, the condenser structure required for dehumidifying the drying airflow is not reasonably designed. The heat exchange time between the drying airflow and the condensate is short and the contact is insufficient, resulting in low condensation efficiency, incomplete dehumidification and long drying time.

[0045] This invention creatively provides a garment processing device in which a condensation zone is formed between the outer side of the rear wall of the inner drum and the inner side of the rear wall of the outer drum. The inner drum, the condensation zone, the drying air outlet, the condensation air duct, the heating air duct and the drying air inlet are sequentially connected to form a drying circuit. The condensation zone and the condensation air duct are connected in series through the drying air outlet.

[0046] When the drying airflow circulates once in the drying circuit, the drying airflow and condensate can complete the first heat exchange in the condensation zone, and the drying airflow and condensate can complete the second heat exchange in the condensation duct; this prolongs the heat exchange time between the drying airflow and condensate, allowing the drying airflow and condensate to come into full contact, thus improving the condensation efficiency.

[0047] Example 1

[0048] like Figures 1 to 3 As shown, this embodiment provides a clothing processing device, including a base 42, an outer cylinder, a door 41, an inner cylinder 15, a condensing air duct 2, and a heating air duct 31. The outer cylinder is horizontally placed on the base 42 and includes an outer cylinder peripheral wall 11 and an outer cylinder rear wall 12. One axial end of the outer cylinder peripheral wall 11 forms an outer cylinder opening, and a drying air inlet 13 is provided at the outer cylinder opening. The other axial end of the outer cylinder peripheral wall 11 is provided with an outer cylinder rear wall 12, and a drying air outlet 14 is provided at the outer cylinder rear wall 12. Specifically, a door seal is provided at the outer cylinder opening. The door seal has an annular structure, and a clothing loading / unloading opening is formed inside the door seal. The clothing loading / unloading opening corresponds to and communicates with the outer cylinder opening. The clothing loading / unloading opening is used to load and unload clothing. The peripheral wall of the door seal forms a drying air inlet 13. The door 41 is located at the clothing loading / unloading opening and is used to open or close the clothing loading / unloading opening.

[0049] The inner tube 15 is rotatably disposed inside the outer tube, and clothing can be placed inside the inner tube 15. The inner tube 15 includes an inner tube peripheral wall and an inner tube rear wall 151. One axial end of the inner tube peripheral wall forms the inner tube opening, and the other axial end of the inner tube peripheral wall is provided with the inner tube rear wall 151. Both the inner tube peripheral wall and the inner tube rear wall 151 are provided with ventilation holes, which connect the inner tube 15 and the outer tube. A condensation zone 16 is formed between the outer surface of the inner tube rear wall 151 and the inner surface of the outer tube rear wall 12.

[0050] The inner drum 15, condensation zone 16, drying air outlet 14, condensation air duct 2, heating air duct 31, and drying air inlet 13 are sequentially connected to form a drying circuit, in which drying airflow can circulate; the condensation zone 16 and condensation air duct 2 are connected in series through the drying air outlet 14, which can extend the flow path of the drying airflow and improve the evaporation efficiency of moisture on the clothes inside the inner drum; condensate 5 and drying airflow can flow through both the condensation zone 16 and the condensation air duct 2;

[0051] When the garment processing equipment is running the drying program, the drying airflow and condensate 5 flowing through the condensation zone 16 can exchange heat, and the drying airflow and condensate 5 flowing through the condensation duct 2 can also exchange heat. The drying airflow flowing through the condensation zone 16 all enters the condensation duct 2, so that the drying airflow can be condensed multiple times, dehumidifying thoroughly and improving drying efficiency.

[0052] The drying airflow achieves first condensation when passing through the condensation zone 16 and second condensation when passing through the condensation duct 2. Therefore, the position of the drying air outlet 14 is important, which will be further explained below; relative to the edge of the outer cylinder rear wall 12, the drying air outlet 14 is closer to the centerline of the outer cylinder rear wall 12. Figure 3 The red arrow in the middle indicates the flow path of the drying airflow;

[0053] Preferably, the center lines of the drying air outlet 14 and the rear wall 12 of the outer cylinder are on the same horizontal plane;

[0054] When the drying airflow circulates once in the drying circuit, the drying airflow and condensate 5 can complete the first heat exchange in the condensation zone 16, and the drying airflow and condensate 5 can complete the second heat exchange in the condensation duct 2. This prolongs the heat exchange time between the drying airflow and condensate 5, increases the heat exchange area between the drying airflow and condensate 5, and ensures full contact between the drying airflow and condensate 5, thereby improving condensation efficiency, thoroughly dehumidifying, and shortening the drying time.

[0055] In order to allow more drying airflow to exchange heat with condensate 5 in condensation zone 16 before entering condensation duct 2, the design only forms ventilation holes at the lower end of the rear wall 151 of the inner cylinder. That is, in the vertical direction, the position of the ventilation holes is lower than the position of the drying air outlet 14. In this way, the drying airflow in the inner cylinder 15 enters the outer cylinder through the ventilation holes, then flows from bottom to top and exchanges heat with the condensate 5 flowing through the inner side of the rear wall 12 of the outer cylinder before entering the condensation duct 2.

[0056] The heat exchange efficiency between the drying airflow and the condensate 5 in the condensing air duct 2 is related to the degree of dispersion of the condensate 5. The more dispersed the condensate 5 is, the larger the heat exchange area between the condensate 5 and the drying airflow, and the higher the heat exchange efficiency. The following is a further explanation: A first external water inlet 21 is formed at the upper end of the side wall of the condensing air duct 2. A first external spray valve is provided at the first external water inlet 21. The external condensate 5 can be sprayed into the condensing air duct 2 through the first external spray valve.

[0057] Furthermore, the first external spray valve can be controlled to open or close and the valve opening size of the first external spray valve can be adjusted according to actual needs; and / or the first external spray valve is rotatably installed at the external water inlet, and the first external spray valve can be controlled to rotate according to actual needs, so that the condensate 5 is dispersed into the condensate duct 2 with a larger area.

[0058] The side wall of the condensing duct 2 also forms a second external water inlet, and a second external spray valve is installed at the second external water inlet; the second external spray valve can be controlled to open or close, and the valve opening size of the second external spray valve can be adjusted according to actual needs; there are multiple second external water inlets, and each second external water inlet is equipped with a second external spray valve; the inner side of the side wall of the condensing duct 2 is provided with multiple water storage tanks 22, and the multiple water storage tanks 22 and the multiple second external spray valves are paired one-to-one. It should be connected; each water storage tank 22 has a water storage tank outlet 221 formed on the side wall facing the condensing air duct 2; external condensate 5 can enter the corresponding water storage tank 22 through the second external spray valve, and the water storage tank 22 can deliver condensate 5 to the condensing air duct 2 through the corresponding water storage tank outlet 221; specifically, the condensate 5 in the water storage tank 22 can enter the condensing air duct 2 in the form of water droplets, increasing the heat exchange area between the condensate 5 and the drying airflow in the condensing air duct 2, and at the same time reducing the overall size of the clothing processing equipment.

[0059] When the clothing processing equipment runs the drying program, it requires a lot of condensate 5. In order to improve the utilization rate of condensate 5, this embodiment proposes that the condensation duct 2 be set on the outer side of the rear wall 12 of the outer cylinder; the bottom of the condensation duct 2 is provided with a water storage tank 23, which can collect the condensate 5 flowing through the condensation duct 2; the water storage tank 23 and the rear wall 12 of the outer cylinder are connected through the water storage tank outlet hole 231, and the water storage tank 23 can deliver condensate 5 to the condensation zone 16 through the water storage tank outlet hole 231; thus, the cooling capacity of the condensate 5 is fully utilized and the waste of condensate 5 is avoided.

[0060] Furthermore, a water baffle 19 is provided at one end of the water outlet 231 of the water storage tank near the condensation zone 16; under the action of the water baffle 19, the condensate 5 discharged through the water outlet 231 of the water storage tank can flow to the inner side of the rear wall 12 of the outer cylinder and flow downward along the inner side of the rear wall 12 of the outer cylinder.

[0061] The heat exchange efficiency between the drying airflow and the condensate 5 in the condensation zone 16 is related to the degree of dispersion of the condensate 5. The more dispersed the condensate 5 is, the larger the heat exchange area between the condensate 5 and the drying airflow, and the higher the heat exchange efficiency. This is further explained below. An inner water inlet 17 is formed at the upper end of the outer cylinder rear wall 12. An inner spray valve is provided at the inner water inlet 17. The inner spray valve can spray the condensate 5 onto the inner side of the outer cylinder rear wall 12. The condensate 5 can disperse and flow along the inner side of the outer cylinder rear wall 12. There is no need to set up a separate dispersing structure, which increases the dispersion area of ​​the condensate 5, makes the flow of the condensate 5 balanced and stable, and improves the condensation efficiency.

[0062] Furthermore, the inner spray valve can be controlled to open or close and the valve port size of the inner spray valve can be adjusted according to actual needs; and / or the inner spray valve is rotatably installed at the inner water inlet, and the inner spray valve can be controlled to rotate according to actual needs, so that the condensate 5 is dispersed and flows to the inner side of the outer cylinder rear wall 12 with a larger area.

[0063] Multiple guide ribs 18 are provided at intervals on the inner side of the rear wall 12 of the outer cylinder. All the guide ribs 18 are located below the inner water inlet 17, and at least a portion of the guide ribs 18 are arranged around the drying air outlet 14.

[0064] Multiple guide ribs 18 are inclined relative to the horizontal plane and are staggered; the position and / or extension direction and / or extension length of the guide ribs 18 can be adjusted.

[0065] When the condensate 5 flows through the guide rib 18, the heat exchange time between the condensate 5 and the drying airflow is prolonged and the heat exchange area between the condensate 5 and the drying airflow is increased, thereby improving the condensation effect.

[0066] In addition, a heating element 32 is provided in the heating air duct 31, which is used to heat the drying airflow flowing through the heating air duct 31; specifically, the heating element 32 is an electric heating element 32; the clothing processing equipment also includes a drying fan 33, which is connected to the condensing air duct 2 and the heating air duct 31, and is used to make the drying airflow circulate in the drying circuit;

[0067] Under the action of the drying fan 33, the drying airflow circulates in the drying circuit; when the drying airflow flows through the condensation zone 16, it exchanges heat with the condensate 5 flowing through the inner side of the outer cylinder rear wall 12; when the drying airflow flows through the condensation duct 2, it exchanges heat with the condensate 5 flowing through the condensation duct 2; when the drying airflow flows through the heating duct 31, the heating element 32 can heat the drying airflow; when the drying airflow flows through the inner cylinder 15, it exchanges heat with the clothes inside the inner cylinder 15, so that the moisture on the clothes is converted into water vapor, achieving the drying effect.

[0068] Compared to condensation only in the condensing zone 16 or only in the condensing duct 2, the drying airflow and condensate 5 in this application can undergo two heat exchanges, improving condensation efficiency. When the drying airflow flows through the inner drum 15, it converts the moisture on the clothes into water vapor, and the high-temperature drying airflow is converted into humid airflow. When the humid airflow flows through the condensing zone 16, it exchanges heat with the condensate 5 flowing through the inner side of the outer drum rear wall 12, which can convert some of the water vapor into water. This water can flow downward to the bottom of the outer drum and be discharged through the drain outlet of the outer drum. Then, the humid airflow converges at the drying air outlet 14 and enters the condensing duct 2. In the condensing duct 2, the humid airflow and condensate 5 exchange heat, which can convert the remaining water vapor into water. This water and the condensate 5 in the condensing duct 2 enter the condensing zone 16 through the water storage tank outlet 231, where they can participate in heat exchange again. Then, they flow downward to the bottom of the outer drum and are discharged through the drain outlet of the outer drum.

[0069] A condenser shell is provided on the outer side of the rear wall 12 of the outer cylinder, and a condenser cover is provided on the top of the condenser shell. The condenser shell and the condenser cover form a condenser air duct 2. Specifically, the condenser shell and the outer side of the rear wall 12 of the outer cylinder are integrally injection molded to reduce the thermal resistance of the rear wall 12 of the outer cylinder and the condenser air duct 2 during drying. The outer cylinder 3, after being heated by the drying airflow, can keep the drying airflow circulating in the condenser air duct 2 warm and raise its temperature, reduce heat loss, and achieve faster drying. The condenser shell and the condenser cover are fixed by welding, screws, or clips. The condenser shell and the condenser cover are sealed to prevent water leakage from the condenser air duct 2.

[0070] Example 2

[0071] Based on Embodiment 1, this embodiment proposes that multiple drying air outlets 14 are provided, and the multiple drying air outlets 14 are spaced apart in the horizontal direction;

[0072] The condensing air duct 2 includes a main condensing air duct and multiple branch condensing air ducts. The multiple branch condensing air ducts are spaced apart on the outer side of the rear wall 12 of the outer cylinder. Each branch condensing air duct can be filled with condensate water 5. The air inlet of the multiple branch condensing air ducts and the multiple drying air outlets 14 are connected one-to-one. The air outlet of the multiple branch condensing air ducts and the heating air duct 31 are connected through the main condensing air duct.

[0073] The drying airflow in the condensation zone 16 enters the corresponding condensation branch air ducts through multiple drying air outlets 14 and exchanges heat with the condensate water 5 flowing through the condensation branch air ducts. Then it enters the heating air duct 31 through the main condensation air duct. In the multiple condensation branch air ducts, the drying airflow and the condensate water 5 can exchange heat, which increases the heat exchange area between the drying airflow and the condensate water 5, so that the drying airflow and the condensate water 5 can fully contact each other, improve the condensation efficiency, dehumidify thoroughly, and shorten the drying time.

[0074] Multiple drying air outlets 14 can be independently controlled to open or close. The number and location of the drying air outlets 14 can be controlled to open according to actual needs.

[0075] Example 3

[0076] Unlike Example 2, the cross-section of the condenser duct 2 is a portion of a circle, and the condenser duct 2 and the outer cylinder are coaxially arranged; the condenser duct 2 is connected to multiple drying air outlets 14.

[0077] The drying airflow in the condensation zone 16 enters the condensation duct 2 through multiple drying air outlets 14 and exchanges heat with the condensate 5 flowing through the condensation duct 2 before entering the heating duct 31. This increases the heat exchange area between the drying airflow and the condensate 5, allowing the drying airflow and the condensate 5 to come into full contact, improving the condensation efficiency, ensuring thorough dehumidification, and shortening the drying time.

[0078] Example 4

[0079] Unlike Embodiment 1, in order to further extend the flow path of the drying airflow in the condensation zone 16, this embodiment proposes that multiple baffle ribs be spaced apart on the inner side of the rear wall 12 of the outer cylinder, and that the multiple baffle ribs be positioned close to the drying air outlet 14; the multiple baffle ribs form multiple baffle rib groups, each baffle rib group including an upper baffle rib and a lower baffle rib, the upper baffle rib being positioned above the drying air outlet 14, and the lower baffle rib being positioned below the drying air outlet 14; when the drying airflow above the drying air outlet 14 flows downward, its flow direction changes under the action of the upper baffle rib and it passes over the drying air outlet 14 to flow to the lower baffle rib, and continues to flow downward under the action of the lower baffle rib, and then merges with the drying airflow below the drying air outlet 14, and then enters the condensation air duct 2 through the drying air outlet 14; in this process, the drying airflow can fully contact the condensate water 5, improving the condensation efficiency;

[0080] The lower baffle rib is also designed to allow more drying airflow flowing from bottom to top along the inner side of the outer cylinder rear wall 12 to enter the condenser duct 2 through the drying air outlet 14.

[0081] Example 5

[0082] Based on Example 1, this example proposes that a guide plate be provided at the drying air outlet 14, and the guide plate can be controlled to rotate; when the guide plate is controlled to rotate, the direction of the drying airflow can be adjusted so that the drying airflow and the condensate 5 can be in full contact; or,

[0083] The flow rate of the drying fan 33 and the tilt angle of the guide plate are controlled in a coordinated manner to ensure that the flow rate of the drying airflow meets the condensation requirements.

[0084] Example 6

[0085] This embodiment proposes a control method for a garment processing device. The garment processing device is any one of the garment processing devices described in Embodiments 1 to 5. The garment processing device has a drying program, which includes multiple drying stages. When the garment processing device runs the drying program, the control method includes:

[0086] S1. Determine the current drying stage of the garment processing equipment;

[0087] S2. Control the opening and closing of the first and second external spray valves of the condensing air duct 2 according to the current drying stage, and / or control the opening and closing of the internal spray valve of the condensing zone 16.

[0088] Furthermore, the multiple drying stages include a heating stage, a dehumidification stage, and a cooling stage. When the garment processing equipment is in the heating stage, the drying airflow heats the garments as it flows through the inner drum 15. When the garment processing equipment is in the dehumidification stage, the drying airflow exchanges heat with the garments as it flows through the inner drum 15, causing the water in the garments to be converted into water vapor. The water vapor enters the condensation zone 16 and the condensation duct 2 with the drying airflow and exchanges heat with the condensate 5 to be converted into water. When the garment processing equipment is in the cooling stage, the drying airflow cools the garments inside the inner drum 15.

[0089] S2 includes:

[0090] When the current drying stage is the heating stage, the first and second external spray valves of the condensing air duct 2 are both closed, and the internal spray valve of the condensing zone 16 is also closed; so that the inner side of the rear wall 12 of the outer cylinder and the condensing air duct 2 do not flow with condensate water 5, and the drying airflow rapidly heats up the clothes.

[0091] When the current drying stage is the dehumidification stage, both the first and second external spray valves of the condensing air duct 2 are opened, and the valve opening size of the first and second external spray valves is adjusted according to the flow rate and humidity of the drying airflow flowing through the condensing air duct 2. Similarly, the inner spray valve of the condensing zone 16 is opened, and the valve opening size of the inner spray valve is adjusted according to the flow rate and humidity of the drying airflow flowing through the condensing zone 16. This ensures that the inner side of the rear wall 12 of the outer cylinder and the condensing air duct 2 are both filled with condensate water 5, allowing the drying airflow in the condensing zone 16 and the condensing air duct 2 to fully contact the condensate water 5 and improve the condensation efficiency.

[0092] When the current drying stage is the cooling stage, the first and second external spray valves of the condensing air duct 2 are both closed, and the internal spray valve of the condensing zone 16 is also closed; so that the inner side of the rear wall 12 of the outer cylinder and the condensing air duct 2 do not flow with condensate water 5, and the drying airflow rapidly cools the clothes.

[0093] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
