[0045] In existing heat pump-type clothes processing equipment, the evaporator and condenser are arranged in two chambers. When the drying air flows through the two chambers, the evaporator can remove water from the drying airflow, and the condenser can heat the drying airflow. However, due to the unreasonable design of the air outlet structure of the two chambers, the drying airflow cannot be discharged from the two chambers in a timely and smooth manner, resulting in the drying airflow not being able to circulate in the drying flow path, insufficient drying airflow flow, and reduced drying efficiency.

[0046] The present invention creatively provides a two-device box structure for use in a heat pump type clothes processing device. The two-device box structure includes two device boxes and two device covers. The two device covers are buckled and connected to the two device boxes to form two device cavities. An evaporator and a condenser are sequentially arranged in the two device cavities along the flow direction of the drying airflow. The two device boxes include an air outlet wall, which is formed with an air outlet for the two device boxes communicating with the two device cavities. The flow area of ​​the air outlet for the two device boxes is larger than the heat exchange area of ​​the evaporator and the heat exchange area of ​​the condenser.

[0047] The structure of the air outlet of the two device boxes has been optimized so that the drying airflow in the two device cavities can be discharged in a timely, smooth and maximized manner. The drying airflow circulates in the drying flow path to ensure sufficient drying airflow flow, thereby improving the drying efficiency. This solves the problem that the drying airflow cannot be discharged from the two device cavities in a timely and smooth manner due to the unreasonable design of the air outlet structure of the two device cavities, and solves the problem that the drying airflow cannot be effectively circulated in the drying flow path, the drying airflow flow is insufficient and the drying efficiency is reduced.

[0052] <Air Intake Device>

[0053] like Figures 1a to 3b As shown, the air inlet device includes a first air distribution assembly, a first branch air inlet duct 24 and a second branch air inlet duct 25. The first air distribution assembly is arranged between the first outer cylinder 11 and the second outer cylinder 13 and the first air distribution assembly includes a first air distribution shell. The first air distribution shell forms a main air inlet duct 23. The first branch air inlet duct 24, the main air inlet duct 23 and the second branch air inlet duct 25 are arranged in sequence up and down and are connected; the end of the first branch air inlet duct 24 away from the main air inlet duct 23 is connected to the first air inlet, and the end of the second branch air inlet duct 25 away from the main air inlet duct 23 is connected to the second air inlet;

[0054] Specifically, the side wall of the main air inlet 23 is formed with a main air inlet inlet 233, a first main air inlet outlet 231 and a second main air inlet outlet 232 connected to the main air inlet 23, and the first main air inlet outlet 231 and the second main air inlet outlet 232 are arranged opposite to each other; the first branch air inlet 24 is connected between the first main air inlet outlet 231 and the first air inlet, and the second branch air inlet 25 is connected between the second main air inlet outlet 232 and the second air inlet; the drying airflow It can enter the main air inlet 23 through the main air inlet inlet 233, and then enter the first outer tube 11 through the first main air inlet outlet 231 and the first branch air inlet 24, or enter the second outer tube 13 through the second main air inlet outlet 232 and the second branch air inlet 25; the first air inlet and the first branch air inlet 24 and the second air inlet and the second branch air inlet 25 are all soft connections; the main air inlet 23 and the first branch air inlet 24 and the main air inlet 23 and the second branch air inlet 25 are all hard connections.

[0055] The first air distribution component also includes an air inlet baffle 31, which can be movably arranged in the main air inlet duct 23. The air inlet baffle 31 can open the first main air inlet duct outlet 231 and close the second main air inlet duct outlet 232, so that the drying airflow in the main air inlet duct 23 can enter the first outer tube 11 through the first branch air inlet duct 24; or the air inlet baffle 31 can close the first main air inlet duct outlet 231 and open the second main air inlet duct outlet 232, so that the drying airflow in the main air inlet duct 23 can enter the second outer tube 13 through the second branch air inlet duct 25; or the air inlet baffle 31 can open both the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232, so that a part of the drying airflow in the main air inlet duct 23 can enter the first outer tube 11 through the first branch air inlet duct 24, and the other part of the drying airflow can enter the second outer tube 13 through the second branch air inlet duct 25.

[0056] The first air distribution shell can be formed as a whole, or the first air distribution shell includes a first air distribution shell body 21 and a first air distribution seat body 22; the first air distribution shell body 21 is arranged on the first air distribution seat body 22 and forms a main air inlet duct 23, the main air inlet duct 23 is a columnar structure, the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232 are arranged at intervals along the circumference of the main air inlet duct 23, and the main air inlet duct inlet 233 is located at one axial end of the main air inlet duct 23; the air inlet baffle 31 is an arc structure, and the air inlet baffle 31 is coaxially arranged with the main air inlet duct 23; the air inlet baffle 31 is rotatably arranged in the main air inlet duct 23, and the rotation of the air inlet baffle 31 can open and close the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232.

[0057] The first air distribution assembly also includes a first bracket 32, which is rotatably disposed in the main air inlet duct 23. An air inlet baffle 31 is disposed on the first bracket 32; the air inlet baffle 31 can rotate synchronously with the first bracket 32. Specifically, the first bracket 32 ​​includes a first axial bracket 321 and a first radial bracket 322. The first axial bracket 321 extends axially along the main air inlet duct 23 and is coaxially disposed with the main air inlet duct 23. The first radial bracket 322 extends radially along the main air inlet duct 23, and one end of the first radial bracket 322 is connected to a side wall of the first axial bracket 321, and the other end of the first radial bracket 322 is connected to the air inlet baffle 31. When the first axial bracket 321 rotates, the first radial bracket 322 rotates with the air inlet baffle 31.

[0058] A first axial hole is formed on the side of the first air distribution shell 21 away from the first air distribution seat body 22, and the first axial hole is coaxially arranged with the main air inlet duct 23; the first air distribution assembly also includes a first drive motor 33 and a first limit frame 35; the first drive motor 33 is arranged outside the main air inlet duct 23 and the output shaft of the first drive motor 33 passes through the first axial hole and is drive-connected to one end of the first axial frame 321; the first limit frame 35 is arranged in the main air inlet duct 23 and the first limit frame 35 abuts against the other end of the first axial frame 321, which is used to play an axial limiting role on the first axial frame 321; specifically, the first limit frame 35 is Z-shaped.

[0059] In order to solve the problem of loose sealing when the air inlet baffle 31 closes the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232, the present embodiment proposes that the air inlet baffle 31 can slide along the radial direction of the rotating shaft of the air inlet baffle 31; when the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 is sealed and connected to the side wall of the main air inlet duct 23; when the air inlet baffle 31 opens the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 is spaced apart from the side wall of the main air inlet duct 23; the flow area of ​​the air inlet baffle 31 is greater than the flow area of ​​any main air inlet duct outlet; the air inlet baffle 31 can completely block the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232;

[0060] Furthermore, a first sealing ring is provided at the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232. The first sealing ring is located within the main air inlet duct 23 and protrudes from the inner wall of the main air inlet duct 23. The first sealing ring is made of rubber material. The air inlet baffle 31 is slidably provided on the first radial frame 322, and a first elastic member 34 is provided between the air inlet baffle 31 and the first radial frame 322.

[0061] When the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, under the action of the first elastic member 34, the air inlet baffle 31 abuts against the first sealing ring; the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232 is tightly sealed to reduce air leakage, so that the drying air in the main air inlet duct 23 flows smoothly to the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232; when the air inlet baffle 31 opens the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, under the action of the first elastic member 34, the drying air in the main air inlet duct 23 flows smoothly to the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232. The air inlet baffle 31 is separated from the side wall of the main air inlet duct 23, so that the air inlet baffle 31 can rotate smoothly, reducing the friction between the air inlet baffle 31 and the inner wall of the main air inlet duct 23, reducing the torque of the first drive motor 33, and reducing the abnormal noise caused by friction; Specifically, a first sliding hole is formed at one end of the first radial frame 322 close to the air inlet baffle 31, and a first sliding rod is provided on the side of the air inlet baffle 31 close to the first radial frame 322. The first sliding rod is slidably disposed in the first sliding hole, and a first elastic member 34 is provided between the first sliding rod and the bottom wall of the first sliding hole;

[0062] When the air inlet baffle 31 rotates and approaches the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 cooperates with the first sealing ring and the air inlet baffle 31 abuts against the first sealing ring; when the air inlet baffle 31 rotates and moves away from the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the air inlet baffle 31 separates from the first sealing ring and the air inlet baffle 31 is spaced apart from the side wall of the main air inlet duct 23.

[0063] To address the problem that when the air inlet baffle 31 blocks the first main air inlet duct outlet 231, the dry air flow in the main air inlet duct 23 cannot flow smoothly to the second main air inlet duct outlet 232, or when the air inlet baffle 31 blocks the second main air inlet duct outlet 232, the dry air flow in the main air inlet duct 23 cannot flow smoothly to the first main air inlet duct outlet 231, this embodiment proposes that first blocking ribs are provided at the first main air inlet duct outlet 231 and the second main air inlet duct outlet 232;

[0064] When the air inlet baffle 31 closes the first main air inlet duct outlet 231 or the second main air inlet duct outlet 232, the first baffle rib can close the gap between the air inlet baffle 31 and the side wall of the main air inlet duct 23, thereby playing a wind-blocking role, reducing the flow of drying air into the gap between the air inlet baffle 31 and the side wall of the main air inlet duct 23, improving the sealing performance of the air inlet baffle 31, and allowing the drying air to flow toward the main air inlet duct outlet in an open state, thereby improving the drying efficiency.

The end of the first outlet air duct 44 away from the main air outlet duct 43 is connected to the first air outlet, and the end of the second outlet air duct 45 away from the main air outlet duct 43 is connected to the second air outlet.

[0067] Specifically, the side wall of the main air outlet 43 is formed with a main air outlet, a first main air outlet inlet 431 and a second main air outlet inlet 432 connected to the main air outlet 43, and the first main air outlet inlet 431 and the second main air outlet inlet 432 are arranged opposite to each other; the first outlet air duct 44 is connected between the first main air outlet inlet 431 and the first air outlet, and the second outlet air duct 45 is connected between the second main air outlet inlet 432 and the second air outlet; the drying air flow in the first outer cylinder 11 can pass through the first outlet air duct The air outlet duct 44 and the first main air outlet duct inlet 431 enter the main air outlet duct 43, and the drying air flow in the second outer cylinder 13 can enter the main air outlet duct 43 through the second outlet air duct 45 and the second main air outlet duct inlet 432.

[0071] A second axial hole is formed on the side of the second air distribution shell 41 away from the second air distribution seat body 42, and the second axial hole is coaxially arranged with the main air outlet 43; the second air distribution assembly also includes a second drive motor 53 and a second limit frame 55; the second drive motor 53 is arranged outside the main air outlet 43 and the output shaft of the second drive motor 53 passes through the second axial hole and is drive-connected to one end of the second axial frame 521; the second limit frame 55 is arranged in the main air outlet 43 and the second limit frame 55 abuts against the other end of the second axial frame 521, which is used to play an axial limiting role on the second axial frame 521; specifically, the second limit frame 55 is Z-shaped.

[0072] In response to the problem of loose sealing when the air outlet baffle 51 closes the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432, the present embodiment proposes that the air outlet baffle 51 can slide along the radial direction of the rotating shaft of the air outlet baffle 51; when the air outlet baffle 51 closes the first main air outlet duct inlet 431 or the second main air outlet duct inlet 432, the air outlet baffle 51 is sealed and connected to the side wall of the main air outlet duct 43; when the air outlet baffle 51 opens the first main air outlet duct inlet 431 or the second main air outlet duct inlet 432, the air outlet baffle 51 is spaced apart from the side wall of the main air outlet duct 43; the flow area of ​​the air outlet baffle 51 is greater than the flow area of ​​any main air outlet duct inlet; the air outlet baffle 51 can completely block the first main air outlet duct inlet 431 or the second main air outlet duct inlet 432;

[0073] Furthermore, a second sealing ring is provided at the inlet 431 of the first main air outlet duct and the inlet 432 of the second main air outlet duct. The second sealing ring is located in the main air outlet duct 43 and protrudes from the inner wall of the main air outlet duct 43. The second sealing ring is made of rubber material.

[0074] The air outlet baffle 51 is slidably disposed on the second radial frame 522 , and a second elastic member 54 is disposed between the air outlet baffle 51 and the second radial frame 522 ;

[0075] When the air outlet baffle 51 closes the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 abuts against the second sealing ring under the action of the second elastic member 54; the first main air outlet inlet 431 or the second main air outlet inlet 432 is tightly sealed to reduce air leakage, so that the drying air flow can smoothly enter the main air outlet 43 through the first main air outlet inlet 431 or the second main air outlet inlet 432; when the air outlet baffle 51 opens the first main air outlet inlet 431 or the second main air outlet inlet 432, the air outlet baffle 51 abuts against the second sealing ring under the action of the second elastic member 54; , the air outlet baffle 51 is separated from the side wall of the main air outlet duct 43; the air outlet baffle 51 rotates smoothly, the friction between the air outlet baffle 51 and the inner wall of the main air outlet duct 43 is reduced, the torque of the second drive motor 53 is reduced, and the abnormal noise caused by friction is reduced; specifically, a second sliding hole is formed at one end of the second radial frame 522 close to the air outlet baffle 51, and a second sliding rod is provided on the side of the air outlet baffle 51 close to the second radial frame 522. The second sliding rod is slidably provided in the second sliding hole, and a second elastic member 54 is provided between the second sliding rod and the bottom wall of the second sliding hole;

[0077] To address the problem that when the air outlet baffle 51 blocks the first main air outlet duct inlet 431, the dry air in the main air outlet duct 43 cannot flow smoothly to the main air outlet outlet, or when the air outlet baffle 51 blocks the second main air outlet duct inlet 432, the dry air in the main air outlet duct 43 cannot flow smoothly to the main air outlet outlet, this embodiment proposes that second blocking ribs are provided at the first main air outlet duct inlet 431 and the second main air outlet duct inlet 432;

[0078] When the air outlet baffle 51 closes the first main air outlet duct inlet 431 or the second main air outlet duct inlet 432, the second baffle rib can close the gap between the air outlet baffle 51 and the side wall of the main air outlet duct 43; it plays a wind blocking role, reduces the drying airflow flowing into the gap between the air outlet baffle 51 and the side wall of the main air outlet duct 43, improves the sealing of the air outlet baffle 51, and improves the drying efficiency.

[0079] <Blower and two-device components>

[0080] like Figures 5a to 7b As shown, the fan 6 and the two-device assembly 7 are arranged between the first outer cylinder 11 and the second outer cylinder 13. A main air inlet 233 is formed on the side of the first air distribution housing close to the two-device assembly 7, and a main air outlet is formed on the side of the second air distribution housing close to the fan 6. The main air outlet, the fan 6, the two-device assembly 7 and the main air inlet 233 are connected in sequence. The fan 6 is used to provide power to the drying airflow.

[0081] Specifically, the first clothes processing drum, the first outlet air duct 44, the main air outlet duct 43, the fan 6, the two-device assembly 7, the main air inlet duct 23 and the first branch air inlet duct 24 are connected in sequence to form a first drying air flow circuit. When the air inlet baffle 31 opens the first main air inlet duct outlet 231 and the air outlet baffle 51 opens the first main air outlet duct inlet 431, the first drying air flow circuit is connected, and the first clothes processing drum can be dried; the second clothes processing drum, the second outlet air duct 45, the main air outlet duct 43, the fan 6, the two-device assembly 7, the main air inlet duct 23 and the second branch air inlet duct 25 are connected in sequence to form a second drying air flow circuit. The air inlet baffle 31 opens the first main air inlet duct outlet 231 and the air outlet baffle 51 opens the first main air outlet duct inlet 431. When the second main air inlet duct outlet 232 is opened and the air outlet baffle 51 opens the second main air outlet inlet 432, the second drying air flow circuit is connected and the second clothing processing drum can be dried; when the air inlet baffle 31 opens both the first main air inlet duct outlet 231 and the first main air outlet inlet 431 and the air outlet baffle 51 opens both the second main air inlet duct outlet 232 and the second main air outlet inlet 432, the first drying air flow circuit and the second drying air flow circuit are connected, and the first clothing processing drum and the second clothing processing drum can be dried at the same time; the structure is simple and the size is small, a variety of drying modes can be realized, and the weight and cost of the clothing processing equipment are reduced.

[0082] Furthermore, the two-device assembly 7 includes a two-device box structure 71, and the two-device box structure 71 includes two-device boxes 711 and two-device covers 712. The two-device covers 712 are snap-fitted and connected to the two-device boxes 711 to form two-device cavities; along the flow direction of the drying airflow, the evaporator 721 and the condenser 722 are sequentially arranged in the two-device cavities; the evaporator 721 is used to dehumidify the drying airflow, and the condenser 722 is used to heat the drying airflow; the two-device box 711 includes an air outlet wall 713, and the air outlet wall 713 forms a two-device box air outlet 714 that is connected to the two-device cavities; the flow area of ​​the two-device box air outlet 714 is larger than the heat exchange area of ​​the evaporator 721 and the heat exchange area of ​​the condenser 722, so that the drying airflow in the two-device cavities is discharged to the main air inlet duct 23 through the two-device box air outlet 714 with a larger flow rate, thereby reducing the flow resistance of the drying airflow.

[0083] Furthermore, the air outlet 714 of the two-device box includes a main air outlet 7141 and an air outlet expansion port. The flow area of ​​the main air outlet 7141 is equal to the heat exchange area of ​​the evaporator 721 and the heat exchange area of ​​the condenser 722; the air outlet expansion port is formed by the edge of the main air outlet 7141 protruding along the air outlet wall toward the outside of the main air outlet 7141.

[0084] In order to solve the problem that the flow area of ​​the air outlet 714 of the two device boxes cannot be maximized, this embodiment proposes that the air outlet expansion includes a relatively arranged upper air outlet expansion 7142 and a lower air outlet expansion 7143. The upper air outlet expansion 7142 is formed by the upper side wall of the main air outlet 7141 protruding toward the upper edge of the air outlet wall 713, and the lower air outlet expansion 7143 is formed by the lower side wall of the main air outlet 7141 protruding toward the lower edge of the air outlet wall 713; the flow area of ​​the air outlet 714 of the two device boxes is increased, so that more drying airflow can quickly enter the main air inlet duct 23, reduce the use of air inlet wall materials, and reduce the flow resistance of the drying airflow.

[0085] Furthermore, the two-device box 711 further includes a first side wall 716 and a second side wall 717 and a bottom wall 715 disposed opposite each other; the left edge of the air outlet wall 713 is connected to the first side wall 716, and the right edge of the air outlet wall 713 is connected to the second side wall 717; the upper edge of the air outlet wall 713 protrudes from the two-device cover 712, and the lower edge of the air outlet wall 713 protrudes from the bottom wall 715;

[0086] At least a portion of the structure of the upper air outlet expansion opening 7142 is similar to the structure of the upper edge, and at least a portion of the structure of the lower air outlet expansion opening 7143 is similar to the structure of the lower edge.

[0087] To address the problem of a complex spraying structure required to clean debris from the surface of the evaporator 721, this embodiment proposes that the two-device cover 712 includes an air inlet wall 718 disposed opposite the air outlet wall 714. The air inlet wall 718 is connected between the first side wall 716 and the second side wall 717. The air inlet wall 718 forms a two-device box air inlet 7181. The evaporator 721 is disposed near the two-device box air inlet 7181.

[0088] A spray box 73 is provided at the bottom of the two-vessel cover 712. A spray chamber is formed between the two-vessel cover 712 and the spray box 73. The projection of the spray box is located between the two-vessel box air inlet 7181 and the evaporator 721. The two-vessel cover 712 is formed with a spray water inlet connected to the spray chamber. The spray water inlet faces the upper side of the two-vessel cover 712. A spray water inlet connector 74 is provided at the spray water inlet.

[0089] The spray box 73 is formed with a spray outlet connected to the spray chamber, and the spray outlet is directed to the windward side of the evaporator 721; there are multiple spray outlets, and the multiple spray outlets are arranged in sequence along the length direction of the evaporator 721; the external water enters the spray chamber through the spray water inlet joint, and is then sprayed toward the evaporator through the spray outlet. Under the action of the spray water, the hair debris attached to the surface of the evaporator 721 is separated from the evaporator 721 and discharged from the two cavities with the water; the flushing force of the water flow is increased, and the hair debris on the surface of the evaporator 721 can be better flushed.

[0090] In response to the problem that the spray water cannot be discharged from the two cavities in time, this embodiment proposes that the bottom wall 715 is arranged to be inclined along the flow direction of the drying airflow; the bottom wall 715 is surrounded by a water storage chamber, and a drainage joint 75 is provided on the side of the bottom wall 715 away from the evaporator 721; the drainage joint 75 is connected to the water storage chamber, and the drainage joint 75 is arranged to be inclined along the flow direction of the drying airflow; the spray water enters the liquid storage chamber and is then discharged through the drainage joint 75; since the bottom wall 715 and the drainage joint 75 are both arranged to be inclined, the spray water can be discharged quickly and thoroughly without causing accumulation of spray water.

[0091] To address the problem that the spray water cannot cover the entire heat exchange surface of the evaporator 721, this embodiment proposes that a nozzle is provided at the spray outlet, and the nozzle can swing up and down and left and right so that the water sprayed by the nozzle can cover the heat exchange surface of the evaporator 721.

[0092] The fan 6 forms a fan cavity, the fan cavity forms a fan cavity air inlet in the axial direction of the fan cavity, and the fan cavity forms a fan cavity air outlet in the radial direction of the fan cavity; the fan cavity air inlet is connected to the outlet of the main air outlet, the fan cavity air outlet is connected to the air inlets of the two-device boxes, and the air outlets of the two-device boxes are connected to the inlet 233 of the main air inlet; preferably, the air inlet device, the two-device assembly 7, the fan 6 and the air outlet device form an H-shaped structure.

[0093] The air inlet baffle 31 and the air outlet baffle 51 are controlled to move, so that any clothing processing drum can be dried separately or multiple clothing processing drums can be dried at the same time; at the same time, the flow rate of the drying airflow entering any clothing processing drum and the flow rate of the drying airflow discharged from any clothing processing drum can be adjusted; specifically, when the first main air inlet duct outlet 231 is in the open state, the air inlet baffle 31 is rotated to adjust the opening size of the first main air inlet duct outlet 231, thereby adjusting the flow rate of the drying airflow entering the first clothing processing drum; when the second main air inlet duct outlet 232 is in the open state, the air inlet baffle 31 is rotated to adjust the opening size of the second main air inlet duct outlet 232, thereby adjusting the flow rate of the drying airflow entering the second clothing processing drum.
