[0044] In the existing water-cooled drying clothing processing equipment, the structural design of the condenser required for dehumidifying the drying airflow is unreasonable, the heat exchange time between the drying airflow and the condensed water is short and the contact is insufficient, resulting in low condensation efficiency, incomplete dehumidification and long drying time;

[0045] The present invention creatively provides a clothes processing device, wherein a condensation area is formed between the outer side surface of the rear wall of the inner drum and the inner side surface of the rear wall of the outer drum, the inner drum, the condensation area, 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, and the condensation area 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 condensed water can complete the first heat exchange in the condensation area, and the drying airflow and condensed water can complete the second heat exchange in the condensation duct; the heat exchange time of the drying airflow and condensed water is extended, so that the drying airflow and condensed water are fully in contact, thereby improving the condensation efficiency.

[0047] Example 1

[0048] like Figures 1 to 3 As shown, the present embodiment provides a clothing processing device, comprising a base 42, an outer drum, a door body 41, an inner drum 15, a condensing air duct 2 and a heating air duct 31; the outer drum is horizontally placed on the base 42 and comprises an outer drum peripheral wall 11 and an outer drum rear wall 12, an outer drum opening is formed at one axial end of the outer drum peripheral wall 11, and a drying air inlet 13 is provided at the outer drum opening; an outer drum rear wall 12 is provided at the other axial end of the outer drum peripheral wall 11, and a drying air outlet 14 is provided on the outer drum rear wall 12; specifically, a door seal is provided at the outer drum opening, the door seal is annular in structure, a clothing taking-in and putting-out opening is formed inside the door seal, the clothing taking-in and putting-out opening corresponds to and is connected with the outer drum opening, and the clothing taking-in and putting-out opening is used for taking-in and putting-out clothing; a drying air inlet 13 is formed on the peripheral wall of the door seal; the door body 41 is provided at the clothing taking-in and putting-out opening, and is used for opening or closing the clothing taking-in and putting-out opening;

[0049] The inner drum 15 is rotatably arranged in the outer drum, and clothes can be placed in the inner drum 15; the inner drum 15 includes an inner drum peripheral wall and an inner drum rear wall 151, an inner drum opening is formed at one axial end of the inner drum peripheral wall, and the inner drum rear wall 151 is provided at the other axial end of the inner drum peripheral wall; ventilation holes are formed on both the inner drum peripheral wall and the inner drum rear wall 151, and the ventilation holes communicate with the inner drum 15 and the outer drum; a condensation area 16 is formed between the outer side surface of the inner drum rear wall 151 and the inner side surface of the outer drum rear wall 12;

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

[0051] When the clothing processing equipment runs the drying program, the drying air flow flowing through the condensation area 16 and the condensed water 5 can be heat exchanged, and the drying air flow flowing through the condensation duct 2 and the condensed water 5 can be heat exchanged; the drying air flow flowing through the condensation area 16 enters the condensation duct 2, so that the drying air flow can be condensed multiple times, dehumidified thoroughly, and the drying efficiency is improved.

[0052] The drying airflow can achieve the first condensation when it flows through the condensation area 16, and can achieve the second condensation when it flows through the condensation air duct 2. Therefore, the position of the drying air outlet 14 is relatively 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 center line 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 outer drum rear wall 12 are on the same horizontal plane;

[0054] When the drying airflow circulates once in the drying circuit, the drying airflow and the condensed water 5 can complete the first heat exchange in the condensation area 16, and the drying airflow and the condensed water 5 can complete the second heat exchange in the condensation duct 2; the heat exchange time of the drying airflow and the condensed water 5 is extended, and the heat exchange area of ​​the drying airflow and the condensed water 5 is increased, so that the drying airflow and the condensed water 5 are fully in contact, the condensation efficiency is improved, the dehumidification is thorough, and the drying time is shortened.

[0055] In order to allow more drying air to exchange heat with the condensed water 5 in the condensation area 16 and then enter the condensation duct 2, it is designed that only the lower end of the inner cylinder rear wall 151 is formed with ventilation holes, 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 air flow in the inner cylinder 15 enters the outer cylinder through the ventilation holes, then flows from bottom to top and exchanges heat with the condensed water 5 flowing through the inner side surface of the outer cylinder rear wall 12, and then enters the condensation duct 2.

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

[0057] Further, the first external spray valve can be controlled to be opened or closed and the valve opening size of the first external spray valve can be adjusted, 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 can be rotatably arranged at the external water inlet, and the first external spray valve can be controlled to rotate according to actual needs, so that the condensed water 5 is dispersed into the condensation air duct 2 with a larger area;

[0058] A second external water inlet is also formed on the side wall of the condensing air duct 2, and a second external spray valve is arranged at the second external water inlet; the second external spray valve can be controlled to be opened or closed and the valve opening size of the second external spray valve can be adjusted, 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 provided with a second external spray valve; the inner side surface of the side wall of the condensing air 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 by one should be connected; each water tank 22 is formed with a water tank outlet hole 221 on the side wall facing the condensation air duct 2; the condensed water 5 from the outside can enter the corresponding water tank 22 through the second external spray valve, and the water tank 22 can transport the condensed water 5 to the condensation air duct 2 through the corresponding water tank outlet hole 221; specifically, the condensed water 5 in the water tank 22 can enter the condensation air duct 2 in the form of water droplets, thereby increasing the heat exchange area between the condensed water 5 and the drying airflow in the condensation air duct 2, and at the same time reducing the overall size of the clothing processing equipment.

[0059] A lot of condensed water 5 is required when the clothing processing device runs a drying program. In order to improve the utilization rate of the condensed water 5, this embodiment proposes that the condensation duct 2 is arranged on the outer surface of the outer cylinder rear wall 12; a water storage tank 23 is provided at the bottom of the condensation duct 2, and the water storage tank 23 can collect the condensed water 5 flowing through the condensation duct 2; the water storage tank 23 and the outer cylinder rear wall 12 are connected through the water storage tank water outlet hole 231, and the water storage tank 23 can transport the condensed water 5 to the condensation area 16 through the water storage tank water outlet hole 231; the cold capacity of the condensed water 5 is fully utilized, and the waste of the condensed water 5 is avoided.

[0060] Furthermore, a water retaining member 19 is provided at one end of the water outlet hole 231 of the water storage tank close to the condensation area 16; under the action of the water retaining member 19, the condensed water 5 discharged through the water outlet hole 231 of the water storage tank can flow to the inner side surface of the rear wall 12 of the outer cylinder and flow downward along the inner side surface of the rear wall 12 of the outer cylinder.

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

[0062] Further, the inner spray valve can be controlled to be opened or closed and the size of the valve opening of the inner spray valve can be adjusted, and the size of the valve opening of the inner spray valve can be adjusted according to actual needs; and / or the inner spray valve can be rotatably arranged at the inner water inlet, and the inner spray valve can be controlled to rotate according to actual needs, so that the condensed water 5 is dispersed over a larger area and flows to the inner side surface of the rear wall 12 of the outer cylinder;

[0063] A plurality of guide ribs 18 are arranged at intervals on the inner side surface of the outer cylinder rear wall 12. The plurality of guide ribs 18 are all 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] The plurality of guide ribs 18 are all inclined relative to the horizontal plane and are arranged in a staggered manner; the position and / or extension direction and / or extension length of the guide ribs 18 are adjustable;

[0065] When the condensed water 5 flows through the guide ribs 18, the heat exchange time between the condensed water 5 and the dry air flow can be prolonged and the heat exchange area between the condensed water 5 and the dry air flow can be increased, thereby improving the condensation effect.

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

[0067] Under the action of the drying fan 33, the drying air flow circulates in the drying circuit; when the drying air flow passes through the condensation area 16, it exchanges heat with the condensed water 5 flowing through the inner side surface of the outer drum rear wall 12, and when the drying air flow passes through the condensation air duct 2, it exchanges heat with the condensed water 5 flowing through the condensation air duct 2; when the drying air flow passes through the heating air duct 31, the heating element 32 can heat the drying air flow; when the drying air flow passes through the inner drum 15, it exchanges heat with the clothes in the inner drum 15, so that the moisture on the clothes is converted into water vapor, thereby achieving a drying effect.

[0068] Compared with condensation in only the condensation zone 16 or only the condensation duct 2, the drying airflow and the condensed water 5 in the present application can undergo two heat exchanges, thereby improving the condensation efficiency; when the drying airflow flows through the inner drum 15, the moisture on the clothes is converted into water vapor, and the high-temperature dry airflow is converted into a humid airflow; when the humid airflow flows through the condensation zone 16, it exchanges heat with the condensed water 5 flowing through the inner side of the rear wall 12 of the outer drum, and part of the water vapor can be converted into water, which can flow downward to the bottom of the outer drum and be discharged through the drain outlet of the outer drum; the humid airflow then converges at the drying air outlet 14 and enters the condensation duct 2, and the humid airflow and the condensed water 5 exchange heat in the condensation duct 2, and the remaining water vapor can be converted into water, which can enter the condensation zone 16 through the water outlet hole 231 of the water storage tank with the condensed water 5 of the condensation duct 2, and can participate in heat exchange again, and then flow downward to the bottom of the outer drum and be discharged through the drain outlet of the outer drum.

[0069] A condensation shell is provided on the outer side of the outer cylinder rear wall 12, and a condensation cover is provided on the upper cover of the condensation shell, and the condensation shell and the condensation cover are arranged to form a condensation air duct 2; specifically, the condensation shell and the outer side of the outer cylinder rear wall 12 are integrally injection-molded to reduce the thermal resistance of the outer cylinder rear wall 12 and the condensation air duct 2 during drying, and the outer cylinder 3 heated by the drying airflow can keep the drying airflow circulating in the condensation air duct 2 warm and increase the temperature, thereby reducing heat loss and achieving faster drying; the condensation shell and the condensation cover are fixed by welding, screws or buckles; the condensation shell and the condensation cover are sealed to prevent water leakage in the condensation air duct 2;

[0070] Example 2

[0071] On the basis of Embodiment 1, this embodiment proposes that a plurality of drying air outlets 14 are provided, and the plurality of drying air outlets 14 are arranged at intervals in the horizontal direction;

[0073] The drying air flow in the condensation area 16 enters the corresponding condensation branch air ducts through multiple drying air outlets 14, and exchanges heat with the condensed water 5 flowing through the condensation branch air ducts, and then enters the heating air duct 31 through the condensation main air duct; in multiple condensation branch air ducts, the drying air flow and the condensed water 5 can both exchange heat, which increases the heat exchange area between the drying air flow and the condensed water 5, makes the drying air flow fully contact with the condensed water 5, improves the condensation efficiency, dehumidifies thoroughly, and shortens the drying time.

[0074] The plurality of drying air outlets 14 can be independently controlled to be opened or closed, and the drying air outlets 14 at corresponding numbers and positions can be controlled to be opened according to actual needs.

[0077] The drying air flow in the condensation area 16 enters the condensation air duct 2 through multiple drying air outlets 14 respectively, and exchanges heat with the condensed water 5 flowing through the condensation air duct 2, and then enters the heating air duct 31; the heat exchange area between the drying air flow and the condensed water 5 is increased, so that the drying air flow is fully in contact with the condensed water 5, the condensation efficiency is improved, the dehumidification is thorough, and the drying time is shortened.
