Description

A ventilation module of a clothes treating apparatus and a clothes treating apparatus TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes treating apparatuses, and in particular to a ventilation module of a clothes treating apparatus and a clothes treating apparatus. BACKGROUND

[0002] At present, the ventilation module of a drum washing machine realizes intelligent on-off of an air duct, performs convection ventilation in the drum after washing is completed, and achieves the effects of odor removal and freshening of clothes. The existing ventilation module of a washing machine adopts a magnet control mode driven by a motor to open and close, solves technical problems such as noise leakage and water splash sealing, but has a complex structure and high cost.

[0003] At present, a commonly used ventilation module structure is shown in FIG. 1', which mainly comprises a shell 1', a damper plate 2', a magnet 3', a micro switch 4', a bidirectional motor 5', and an upper cover 6', etc. The damper plate 2' is assembled with the shell 1' by a rotating shaft to realize rotation opening and closing of the damper plate 2', and then realize opening and closing of the ventilation passage. The paired magnets 3' that cooperate with each other are respectively assembled on the damper plate 2' and the shell 1', and the magnetic pole change thereof is controlled by the bidirectional motor 5' being powered. Specifically, during the washing process, the bidirectional motor 5' controls the paired magnets 3' to exhibit opposite poles, attract each other, the damper plate 2' is close under the action of the attractive force, and the ventilation passage is closed, thereby isolating water splash and foam and blocking noise; after the washing is completed, the bidirectional motor 5' controls the paired magnets 3' to exhibit the same poles, repel each other, the damper plate 2' is far away from each other under the action of the repulsive force, and the ventilation passage is opened, thereby realizing the effect of smooth airflow. This ventilation module structure can realize magnetic pole change by motor driving magnet, thereby completing accurate opening and closing control, but also has problems such as complex structure, difficult assembly, and the need for additional motor driving.

[0004] To solve the above problems, if only all the electronic devices of the traditional ventilation module are cancelled, the ventilation module of the washing machine is in a constant open state, and when high-temperature program washing is performed, condensate water is generated at positions such as the inner frame and front plate of the door of the washing machine due to the high temperature of the internal air, which brings a poor experience to the user, and the positions that often generate condensate water are also in a humid state for a long time, which is easy to breed bacteria and bring trouble to the user.

[0005] This paper proposes a drum washing machine ventilation module technology based on a mechanical structure, which can prevent the formation of condensate water and does not depend on an electric control system, and the cost can be greatly reduced. SUMMARY

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0038] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] The present application first provides a ventilation module 95 of a clothes treatment apparatus, which includes a condensing air duct 1, a condensing mechanism 11 provided in the condensing air duct 1 and having an air flow path longer than the length of the condensing air duct, and a drainage structure for draining condensate.

[0040] The present application provides a ventilation module 95 of a clothes treatment apparatus and a specific structure of the clothes treatment apparatus, which will be described below with reference to a conventional drum washing machine. As shown in FIG. 2, the washing machine 9 includes a cabinet 91, an inner drum 93 and an outer drum 92 provided inside the cabinet 91, the inner drum 93 and the outer drum 92 being fitted into each other, and a rear wall connected to a motor 94, which drives the inner drum 93 to rotate along with laundry and washing water under the drive of the motor 94.

[0041] The drum washing machine 9 is provided with a steam generator or a heating device to perform high-temperature washing or drying. An air exhaust device is provided in the cabinet to exhaust the high-temperature and high-humidity gas in the outer drum to the outside of the cabinet.

[0042] The outer drum 92 and the cabinet 91 are respectively provided with air inlets, the air inlet of the air exhaust device is communicated with the air inlet of the outer drum 92, and the air outlet is communicated with the air inlet of the cabinet through the ventilation module 95, so that the inside of the outer drum is communicated with the outside of the cabinet.

[0043] It is a conventional technology to provide the air exhaust device in the drum washing machine to exhaust the humid gas in the outer drum. The connection mode of the air duct of the air exhaust device, the structure of the air duct, the air flow path, and the setting of the fan can adopt the conventional technology, and no requirement or limitation is made. Any technology existing or to be developed in the future is applicable to the present application, and no further description is made. It should be noted that the humid gas includes, but is not limited to, the high-temperature and high-humidity gas during high-temperature washing and / or drying, and also includes the high-humidity gas during conventional washing, which is collectively referred to as humid air. During the rotation of the inner drum, the air is driven to flow, especially during the spin-drying process, the air in the outer drum is driven to flow, the flowing air is rich in water vapor, enters the air exhaust device through the outer drum, and is finally exhausted to the outside of the cabinet from the ventilation module.

[0044] In the present application, the ventilation module 95 includes the condensing air duct 1, the air inlet of the condensing air duct 1 is connected to the air outlet of the air exhaust device, and the air outlet is communicated with the air inlet at the cabinet, so that the air exhaust device, the ventilation module and the environment outside the cabinet are communicated.

[0045] The condensing mechanism 11 is provided in the condensing air duct 1. The air entering the condensing air duct 1 is cooled by the condensing mechanism 11, and condensate is generated in the condensing air duct 1, so that the air passing through the condensing air duct 1 is cooled and dehumidified, and when it is exhausted from the air outlet, it has little difference from the room temperature and the humidity is greatly reduced, so it will not condense at the air inlet of the cabinet. Generally, the air inlet of the cabinet is provided at the position of the front panel, so there will be no condensate at the position of the door inner frame and the front panel of the washing machine.

[0046] The condensing structure is arranged in the condensing air duct 1, and the condensed water generated when the humid air flows through the condensing mechanism 11 is collected and discharged through the drainage structure. The drainage structure can be directly communicated with the drainage device of the washing machine, or can be communicated with any water receiving container arranged in the washing machine, and no requirement and limitation is made.

[0047] Regarding the condensing mechanism 11 in the condensing air duct 1, the following embodiments are provided:

[0048] Embodiment I

[0049] The washing machine comprises a refrigeration cycle system, which comprises a compressor, a condenser, a throttling device and an evaporator communicated through pipelines. The evaporator can be used as a heat source of a heating device or a steam generating device. The condenser is embedded in the condensing air duct 1 and serves as the condensing mechanism 11 of the present application to cool and dehumidify the humid air entering the condensing air duct 1. By controlling the flow direction of the refrigerant, the evaporator is in a high-temperature state and the condenser is in a low-temperature state during high-temperature washing or drying. The condenser is embedded in the condensing air duct 1 to cool and dehumidify the high-temperature and high-humidity gas discharged.

[0050] The condensing mechanism 11 can be a common finned condenser embedded in the condensing air duct 1. Specifically, the finned condensing mechanism 11 can fill the entire internal space of the condensing air duct 1. The humid air passes through the fins and the condensing pipe to be cooled and generate condensed water.

[0051] Alternatively, the condensing mechanism 11 is arranged at a position away from the air inlet 12 of the condensing air duct 1 to avoid the condensed water formed at the connection between the condensing air duct 1 and the air inlet passage 2 from entering the air exhaust device through the air inlet 12 and being stored in the air exhaust device or flowing back into the inner drum.

[0052] Preferably, the finned condenser comprises a condensing pipe, and the fins are sleeved on the condensing pipe. Adjacent rows of fins are arranged in a staggered manner, so that the air flowing through the condenser forms a turbulent flow between the fins, and the air flow path becomes tortuous, thereby prolonging the air flow path length. The air flow path length is greater than the overall air flow path length (referring to the conventional flow path from the air inlet to the air outlet) in the condensing air duct.

[0053] The condensing mechanism 11 of the refrigeration cycle device of the washing machine is arranged in the condensing air duct 1. During the heating process, the humid air entering the air exhaust device and the ventilation module is cooled and dehumidified by the condensing mechanism 11, and no additional cooling and dehumidifying device needs to be arranged in the condensing air duct 1, thereby reducing the product cost.

[0054] Embodiment II

[0055] The condensing mechanism 11 comprises a condensing plate 111, which is arranged horizontally (parallel or similar to the bottom wall and / or top wall of the condensing air duct 1) in the condensing air duct 1. In this embodiment, only one condensing plate 111 is arranged in the condensing air duct 1.

[0056] The three side ends of the condensing plate 111 are fixedly assembled with the air duct walls of the condensing air duct 1, and an air flow gap 114 is left between the last side end and the corresponding air duct wall of the condensing air duct 1. Specifically, the air duct wall comprises four vertically arranged side walls connected at the top and bottom, and a top wall and a bottom wall connected to the top and bottom of the side walls. A step is arranged on the three side walls of the condensing air duct 1 that are connected to each other. The bottom surface of the condensing plate 111 is placed on the step, so that the three side end surfaces of the condensing plate 111 are sequentially connected to the side walls of the condensing air duct 1, and the last side end surface is left with a flow gap 114 between the corresponding side wall of the condensing air duct 1, for air flow; or the side wall of the condensing air duct 1 is provided with a clamping groove, and the condensing plate 111 is clamped and connected with the condensing air duct 1.

[0057] Alternatively, at least one side end of the condensing plate 111 is fixed or integrally formed with the side wall, and at least one side end is left with a flow gap 114 between the side wall, while the remaining end can only abut against the side wall without being fixed. Preferably, a sealing strip is arranged between the side wall of the condensing air duct 1 and the corresponding condensing plate 111 abutting against it, to prevent wind noise caused by the abutting gap.

[0058] The end of the condensing plate 111 at the flow gap 114 is set as a free end, and the end opposite to the free end is set as a fixed end, which is fixed to the side wall of the condensing air duct 1. As shown in FIGS. 4 and 5, the bottom wall of the condensing air duct 1 on the side of the fixed end of the condensing plate 111 is provided with an air inlet 12, i.e., the air inlet 12 is arranged on the lower part of the bottom wall or the side wall of the condensing air duct 1 away from the flow gap 114.

[0059] The condensing plate 111 horizontally divides the space in the condensing air duct 1 into upper and lower spaces, which are connected through the flow gap 114. The air entering the condensing air duct 1 through the air inlet 12 advances along the space between the bottom surface of the condensing plate 111 and the bottom wall of the condensing air duct 1, changes the flow direction at the flow gap 114, and advances along the flow gap 114 to the space between the top surface of the condensing plate 111 and the top wall of the condensing air duct 1. By arranging the condensing plate 111, the space in the condensing air duct 1 is divided to form a U-shaped air path, which increases the length of the air flow path, the heat exchange time and the heat exchange efficiency.

[0060] During the U-shaped travel of the humid air, continuous heat exchange is performed with the condensing plate 111, and condensate is generated on the surface of the condensing plate 111 and the inner wall of the condensing air duct 1. The top wall of the condensing plate 111 and / or the bottom wall of the condensing air duct 1 is arranged to be inclined, so as to facilitate the flow and convergence of the condensate.

[0061] The condensing plate 111 is made of a material with high heat exchange efficiency, such as aluminum or aluminum alloy. During operation, the air exchanges heat with the bottom surface and the top surface of the condensing plate 111, thereby improving the heat exchange efficiency of the condensing plate 111, reducing the amount of the condensing plate 111, and lowering the cost.

[0062] Embodiment Three

[0063] The condensing mechanism 11 has substantially the same overall structure as that of Embodiment Two, except that a plurality of condensing plates 111 are arranged in the condensing air duct 1. The condensing plates 111 are arranged in parallel or approximately in parallel with each other, and the spacing between the condensing plates 111 is the same and staggered.

[0064] The staggered arrangement refers to the staggered arrangement of the fixed end and the free end of the condensing plate 111. From bottom to top, the fixed end of the bottommost condensing plate 111 is arranged at the air inlet 12, the fixed end of the condensing plate 111 above the bottommost condensing plate 111 is arranged above the flow gap 114 of the bottommost condensing plate 111, the fixed end of the third condensing plate 111 is arranged above the flow gap 114 of the second condensing plate 111, and so on. As shown in FIG. 1, the flow gap 114 corresponding to each condensing plate 111 is arranged in a staggered manner. For example, the flow gap 114 corresponding to the bottommost condensing plate 111 is arranged on the right side of the condensing air duct 1, the flow gap 114 corresponding to the condensing plate 111 above the bottommost condensing plate 111 is arranged on the left side of the condensing air duct 1, and the flow gap 114 corresponding to the condensing plate 111 above the condensing plate 111 above the bottommost condensing plate 111 is arranged on the right side of the condensing air duct 1, and so on. In this way, in the condensing air duct 1, the condensing plates 111, and the top wall / bottom wall of the condensing air duct 1 form a continuous S-shaped air path.

[0065] When a plurality of condensing plates 111 are arranged, the humid air exchanges heat with the bottom surface and the top surface of the adjacent two condensing plates 111 during operation, thereby improving the heat exchange efficiency and the dehumidification effect.

[0066] In this embodiment, since a plurality of condensing plates 111 are arranged, a U-shaped groove or other water guide structure is arranged at the fixed end of the condensing plate 111. The condensed water is discharged from the U-shaped groove / water guide structure, thereby avoiding water accumulation at the connection between the fixed end of each condensing plate 111 above the bottommost condensing plate 111 and the side of the condensing air duct 1.

[0067] Embodiment Four

[0068] The condensing mechanism 11 uses the condensing plate 111 described in Embodiment Two or Embodiment Three.

[0069] To improve the condensation and dehumidification effect, fins 112 are arranged on the condensing plate 111. Preferably, to improve the air flow efficiency and the water drainage effect, a plurality of fins 112 are arranged on the bottom surface of the condensing plate 111.

[0070] The fin 112 is made of the same material as the condensing plate 111 and is integrally formed with the condensing plate 111. A gap is left between the bottom of the fin 112 and the bottom wall of the lower condensing plate 111 or the condensing air duct 1 for air circulation.

[0071] The fin 112 can be arranged on both sides of the condensing plate 111. In the embodiment, preferably, the fin 112 is arranged on the bottom surface of the condensing plate 111.

[0072] Each row of the fin 112 is a whole piece of fin 112. Preferably, each row of the fin 112 has multiple pieces of fin 112, and a gap is left between adjacent fins 112 to improve air circulation efficiency. Further preferably, the fins 112 of adjacent rows are staggered, air is blocked at the fins 112 during the flow process, and small streams are formed to form turbulence during the air flow process, thereby increasing the contact probability and contact time of air with the fins 112 and the condensing plate 111, and improving the heat exchange efficiency.

[0073] The fin 112 can be regularly arranged on the bottom surface of the condensing plate 111, such as parallel to each other. In actual application, the fins 112 can also be arranged in a predetermined rule or even in disorder, including but not limited to parallel arrangement, to increase the turbulence effect and improve the condensing effect.

[0074] Further, in addition to arranging the fin 112 on the condensing plate 111, the fin 112 can also be arranged on the wall of the condensing air duct 1 to increase the dehumidification effect of the condensing air duct. When the fin 112 is arranged on the wall of the condensing air duct 1, the position, angle, and corresponding structure of the fin 112 are arranged based on the convenience of discharging condensed water.

[0075] Further, the condensing plate 111 is arranged in an inclined manner, and the bottommost condensing plate is arranged in a downward inclined manner from the fixed end to the free end, that is, the longitudinal height between the condensing plate 111 and the condensing air duct 1 linearly decreases from the fixed end to the free end.

[0076] The length of the fin 112 on the condensing plate 111 is not equal, and gradually decreases from the fixed end to the free end. The bottom surface of the fin 112 is on the same horizontal plane, or the bottom surface edge line of the fin 112 is parallel to the bottom wall of the condensing air duct 1, which can effectively improve the ventilation efficiency. The length of the fin can be arranged according to the amount of water content in the air to improve the condensing efficiency.

[0077] Embodiment Five

[0078] The condensing mechanism 11 as described in Embodiment Four, comprising condensing plates 111 and fins 112, in this embodiment, the fins 112 are parallel to each other, and each fin 112 is arranged obliquely, the fins 112 of the two adjacent rows of condensing plates 111 are arranged in reverse difference, the arrangement direction of the fins 112 of the upper layer and the lower layer are opposite, and the fins 112 are inclined to different directions. Further, in this embodiment, the fins 112 are inclined to the windward direction, so as to increase the contact area of air and the fins 112, and improve the heat exchange efficiency. Preferably, the inclination angle of the fins 112 is in the range of 45° to 60°.

[0079] Preferably, the flow-through gap 114 at the free end of the condensing plate 111 corresponds to the condensing plate 111 of the upper layer, and a fin 112 is arranged obliquely on the condensing plate 111, and the extension of the windward surface of the fin 112 is tangent to the end surface of the free end of the condensing plate 111 of the lower layer.

[0080] As described in Embodiment Five, the condensing plates 111 are arranged obliquely, the length of the fins 112 on the condensing plates 111 gradually increases from the low point to the high point in the oblique direction, and the bottom surface of the fins 112 of each layer of condensing plates 111 is on the same horizontal plane, or the bottom surface of the fins 112 is parallel to the bottom wall of the condensing air duct 1.

[0081] By arranging the fins 112 in reverse difference and arranging the fins 112 obliquely, the contact area of air and the fins 112 can be increased, and the condensing efficiency can be improved.

[0082] Embodiment Six

[0083] In this embodiment, the condensing mechanism 11 is in a box-shaped structure, and is embedded in the condensing air duct 1. The outer wall of the box body is attached to the inner wall of the condensing air duct 1. The through holes are provided on the bottom wall and the top wall of the box body, and are communicated with the air inlet 12 and the air outlet 13 of the condensing air duct 1. The structure of the through holes is the same as that of the air inlet 12 and the air outlet 13, and sealing strips are arranged at the connecting positions, so as to prevent the humid air from entering the gap between the box body 113 and the condensing air duct 1, and to prevent the condensate water from being stored or the wind noise from being generated.

[0084] The box body 113 is made of aluminum or aluminum alloy, which has high heat exchange efficiency. The humid air is cooled when contacting the side wall of the box body 113, and is condensed into condensate water on the inner wall of the box body 113, and is finally discharged. The fins 112 or the protruding structures with similar effects can be arranged on the side wall of the box body 113, so as to increase the heat exchange area and improve the heat exchange efficiency.

[0085] Preferably, one or more layers of condensing plates 111 are arranged in the box body 113, and the condensing plates 111 are integrally formed with the side walls of the box body 113. Similarly, as described in Embodiment Two and Embodiment Three, a flow gap 114 is arranged between the free end of the condensing plate 111 and the side wall of the box body 113. By arranging the condensing plate 111 and the flow gap 114, a U-shaped or continuous S-shaped air flow path is formed in the box body 113.

[0086] The box body 113 and the condensing plate 111 are made of the same material with high heat conduction efficiency, such as aluminum or aluminum alloy, so that the humid air contacts and exchanges heat with the condensing plate 111, the bottom wall, the top wall, and the side walls of the box body during the flow process. The heat exchange efficiency is further improved.

[0087] The box body 113 and the condensing plate 111 are made of aluminum or aluminum alloy, which has high smoothness and small surface tension, thereby accelerating the condensation and dripping speed.

[0088] The bottom wall of the box body 113 is horizontally arranged, and the top wall is in an arched structure, i.e., the top wall is upwardly and arcuately protruded, so as to avoid that the condensed water condensed on the top wall always condenses on the top wall under the action of surface tension and does not drip down.

[0089] The fins 112 or the protruding structures with the same function as the fins 112 can be arranged on any side wall of the box body 113.

[0090] The integrally formed box body 113 can effectively prevent the humid air from escaping from the connecting gap of the condensing air duct 1, reduce the formation of wind noise, improve the condensation efficiency by using the material with high heat conduction efficiency, and easily collect the condensed water.

[0091] Embodiment Seven

[0092] In this embodiment, the condensing mechanism 11 adopts the box body structure described in Embodiment Six, at least one layer of condensing plate 111 is arranged in the box body 113, and the fins 112 described in Embodiment Four or Embodiment Five are arranged on the condensing plate 111.

[0093] In this embodiment, the specific structure of the condensing mechanism 11 is introduced by taking the arrangement of one layer of condensing plate 111 in the box body 113 as an example.

[0094] The box body 113 is integrally formed with the condensing plate 111 and the fins 112, and the inclined fins 112 are arranged on the bottom surface of the condensing plate 111 and the bottom surface of the top wall of the box body. The vertical length of the fins 112 accounts for about 1 / 3 to 1 / 2 of the height between the bottom wall of the box body and the condensing plate 111, and it is recommended that the end of the fins 112 is on the horizontal median line between the bottom wall of the box body and the condensing plate 111.

[0095] Preferably, the length of the fins 112 on the condensing plate 111 is less than the length of the fins 112 at the top wall of the box, which can increase the heat exchange area and heat exchange efficiency before the air flows out of the condensing mechanism 11, and accelerate the cooling and dehumidification speed. The top wall of the box is an arched structure, which further provides space for lengthening the length of the fins 112, and the length of the fins 112 on the top wall is different, but the ends of the fins 112 are on the same horizontal plane.

[0096] When multiple condensing plates 111 are arranged in the box, similarly, the length of the fins 112 arranged at the top wall (the topmost condensing plate 111) is greater than the length of the fins 112 arranged on the bottom surface of the bottommost condensing plate 111. The air inlet 12 and the air outlet 13 are arranged on the bottom wall or the top wall away from the flow-through gap 114 of the current layer.

[0097] As described in Embodiment Six, the box made of high-thermal-conductivity material can improve the condensing efficiency and facilitate the collection of condensed water, and by arranging longer fins at the position first contacted by the humid gas, the heat exchange area and heat exchange efficiency are increased.

[0098] Embodiment Eight

[0099] In this embodiment, the box 113 of Embodiment Six or Embodiment Seven is integrated with the condensing air duct 1, that is, the side wall of the condensing air duct 1 is the side wall of the box 113, and the condensing air duct 1 is made of aluminum or aluminum alloy material, which can effectively improve the heat exchange efficiency. The condensing plate 111 is directly fixed or integrally formed with the side wall of the condensing air duct 1, and inclined fins 112 are arranged on the bottom surface of the arched top wall. The inclined fins 112 can increase the heat exchange area and heat exchange efficiency.

[0100] The above is a plurality of embodiments of different structures of the condensing mechanism 11 arranged in the condensing air duct 1. In actual application, Embodiments One to Eight can be combined arbitrarily, and any one or more structural details of Embodiments One to Eight can be selected for combination to obtain the specific structure of the desired condensing mechanism 11, which is within the protection scope of the present application.

[0101] Further, as described in the structures of the condensing mechanism 11 in Embodiments Two to Eight, the condensing air duct 1 is generally in the form of a box-shaped structure of a rectangular body, and in actual application, the condensing air duct 1 can be of any structure, including but not limited to a rectangular body, a cylindrical body, an elliptical cylindrical body, and a multi-faced cylindrical body. According to the specific structure of the condensing air duct 1 and the relative position relationship between the air inlet 12 and the air outlet 13, the end of the condensing plate 111 is fixed with the air duct wall of the condensing air duct 1, and at least one flow-through gap 114 for the diversion of humid gas is left between the end and the corresponding air duct wall.

[0102] Further, the different condensing mechanisms 11 provided by embodiments one to seven can all be applied in the condensing air duct 1 provided by embodiment eight (only the air duct, not including the internal fixed or integrally formed fins), i.e. in the orientation shown in Fig. 3, the condensing air duct 1 is a box-like structure with an arched top surface, the bottom wall is provided with an air inlet, and the top wall is provided with an air outlet, and the condensing mechanism 11 provided by embodiments one to seven or the condensing mechanism 11 obtained by combining the structural details according to embodiments one to seven is arranged in the box structure.

[0103] The top wall of the box is arched upward, and the bottom wall is flat. Preferably, the top surface of the bottom wall is inclined, and the lowest point is located at the drainage structure, facilitating the flow of condensed water. The condensing plates 111 are also arranged inclined in the condensing air duct 1, facilitating the condensed water condensed on the top surface of the condensing plates 111 to slide along the top surface of the condensing plates 111. As shown in Fig. 3, the lowest layer of condensing plates 111 is inclined to the drainage structure, i.e. the height between the condensing plates 111 and the bottom wall of the condensing air duct 1 decreases linearly from the fixed end to the free end, so that the condensed water condensed on the condensing plates 111 flows along the top surface of the condensing plates 111 under the action of gravity, and finally drips at the free end, and directly drips into the drainage structure, or drips onto the bottom wall and then flows into the drainage structure.

[0104] When multiple layers of condensing plates 111 are arranged in the condensing air duct 1, the multiple layers of condensing plates 111 are parallel to each other and are all arranged inclined, and the condensing plates 111 are provided with water guide structures, but the condensed water on each layer of condensing plates 111 is finally discharged.

[0105] Specifically, since the multiple layers of condensing plates 111 are parallel to each other, the lowest ends of the condensing plates 111 with free ends on the same side are all at the flow-through gap 114, and the condensed water can directly flow along the top surface of the condensing plates 111 to the most free end under the action of gravity, and flow into the next layer at the flow-through gap 114; while the lowest positions of the remaining layers of condensing plates 111 corresponding to the free ends of the lowest layer of condensing plates 111 at the fixed end are at the connection between the condensing plates 111 and the side wall of the condensing air duct 1, in order to smoothly discharge the condensed water, a drainage groove is provided at the connection between the fixed end of the condensing plates and the side wall of the condensing air duct 1, so as to discharge the condensed water condensed on this layer and the condensed water dripped from the free end of the upper layer of condensing plates 111 from the drainage groove to the next layer of condensing plates 111, and finally into the drainage structure.

[0106] In actual application, the water guide structure can be the drainage groove described above, or any other structure that can guide the condensed water of each layer out and finally discharge into the drainage device, without any requirement or limitation, as long as it can guide and discharge the condensed water and does not accumulate in the condensing air duct 1.

[0107] Alternatively, each layer of condensing plate 111 is arranged in an inclined manner in the condensing air duct 1, and in the longitudinal direction, each layer of condensing plate 111 is low at the free end and high at the fixed end. The condensate formed on the top surface of the condensing plate 111 slides downward to the low end, i.e. the free end, under the action of gravity, and flows to the condensing plate 111 of the next layer at the flow gap 114. The condensate on the condensing plate 111 of the next layer also flows downward, and finally drains into the drainage device.

[0108] To improve the heat exchange efficiency, the condensing plate 111 of Embodiment Two to Embodiment Seven can be a hollow structure, and a heat exchange agent such as water flows in the hollow structure. The hollow structure of the condensing plate 111 forms a loop with the water inlet pipe of the washing machine through a water circuit, or forms a separate water cooling circulation loop, thereby improving the heat exchange efficiency.

[0109] It should be noted that the top wall of the box body or the condensing air duct 1 is in an arched structure, which is also an inclined state. Alternatively, the condensing air duct 1 is arranged in an inclined manner in the space surrounded by the machine shell, so that the top wall and the bottom wall are in an inclined state in the use state. The condensing plate 111 is parallel or substantially parallel to the top wall and / or the bottom wall of the condensing air duct 1, which facilitates the flow and collection of condensate.

[0110] The condensing air duct 1 is arranged in an inclined manner in the machine shell, or the bottom wall of the condensing air duct 1 is in an inclined state. A drainage structure is arranged at the lowest point of the bottom wall, and the drainage structure is in communication with the drainage pipe of the washing machine to drain the collected condensate through the drainage pipe. Alternatively, the drainage structure is in communication with the water receiving structure built-in the washing machine to drain the collected condensate into the water receiving structure. Alternatively, the drainage structure can store part of the condensate, and the user can drain the stored condensate in the drainage structure after each washing.

[0111] Further, the drainage structure includes a water guide step 3, as shown in FIGS. 7 to 9. A water guide structure 3 is arranged at the rear wall of the condensing air duct 1 to quickly guide the condensate generated on the rear wall to the bottom wall. The water guide structure can be a structure with smooth surface and certain hydrophobicity, such as an aluminum alloy plate, so that the condensate is not easy to accumulate on the surface and can quickly slide down to the bottom wall under the action of gravity.

[0112] As shown in FIG. 6, the rear wall of the condensing air duct 1 is provided with a bent portion. The main body of the bent portion is attached to the top surface of the bottom wall. A notch is arranged on the top surface of the rear part of the bottom wall. The rear side of the bent portion is provided with a protrusion directed to the bottom wall. The protrusion of the bent portion is embedded in the notch of the bottom wall. Further, the front side of the protrusion is provided with a hook, and the notch of the bottom wall is correspondingly provided with a recess, so that the notch is generally in a horizontal J-shaped structure. The hook and the recess are in interference fit, so that the rear wall and the bottom wall are embedded and hooked together after assembly.

[0113] The water guide structure 3 comprises a water guide plate 31 which is attached to the rear wall of the condensing air duct. In this embodiment, the water guide plate 31 is laser welded to the rear wall. In actual applications, the water guide plate 31 can be integrated with the rear wall as one structure. The water guide plate 31 is relatively thin (not visible in FIG. 7 due to its small thickness), with a thickness of less than 1 mm, and at least one welding reinforcing rib is provided on the surface to enhance the welding strength.

[0114] The water guide plate 31 is integrally formed with a water guide step 32 at the bottom. The welding step 32 is attached to the bent portion at the bottom of the rear wall. Preferably, the top surface of the water guide step 32 is beveled, and the front end surface is flush with the front end surface of the bent portion, or the front end surface of the water guide step 32 extends forward and downward along the front end surface of the bent portion and is attached to the bottom wall. Preferably, the connection between the water guide step 32 and the water guide plate 31 is rounded to prevent water accumulation.

[0115] A plurality of drainage holes are provided on the bottom wall of the condensing air duct 1. The water guide step 32 and the bent portion extend to the drainage holes in the direction of the front wall on the bottom wall. Preferably, the front end of the water guide step 32 is tangent to the edge of the adjacent drainage hole, and the condensed water formed on the water guide structure 3 directly slides down the water guide plate 31 and the water guide step 32 into the drainage hole.

[0116] At the bottom of the condensing air duct 1, a water guide portion 8 is provided. The water guide portion 8 is a hollow structure, and the drainage holes are in communication with the hollow portion of the insertion portion. After the ventilation module is fixed to the shell, the water guide portion 8 is connected to the window pad, for example, the water guide portion 8 is directly connected to the window pad by insertion connection, and the condensed water in the water guide portion is guided to the window pad and further returned to the inner cylinder.

[0117] Preferably, in this embodiment, the water guide structure 3 is only provided on the rear wall. In actual applications, the water guide structure 3 can be provided on all four side walls. Further, as described in Embodiments Six and Seven of the condensing mechanism 11 above, the water guide structure 3 is integrated with the box body structure, and a water guide step is provided on the box body. When the box body as described above is provided, since the box body itself is made of aluminum alloy material, there is no need to additionally provide a water guide plate 31, and only a water guide step 32 needs to be provided at the bottom of the side wall of the box body.

[0118] A plurality of drainage holes are provided on the bottom wall, and the plurality of drainage holes are evenly distributed, for example, in rows on the bottom wall. The condensed water dripping from each side wall and the fins is discharged into the inner cylinder through the water guide portion 8 and the window pad.

[0119] In the embodiments provided by the application, as shown in Fig. 3, the air inlet 12 and the air outlet 13 of the condensing air duct 1 are both arranged on the same side, and are both arranged at positions away from the corresponding flow-through gap 114 of the bottommost condensing plate 111, that is, the air inlet 12 is arranged on the bottom wall corresponding to the fixed end of the bottommost condensing plate 111, and the air outlet 13 is arranged on the top wall corresponding to the fixed end, so that the path of air flow is the longest, and the condensing and dehumidifying effect is the best. The same side refers to both sides of the vertical mid-plane of the condensing air duct 1 in the length direction of the condensing air duct 1 in the installed state, both on the left side or the right side of the mid-plane, which are collectively referred to as being on the same side, but are not limited to being on the same side of the same side wall. For example, they can be on the left side of the top wall and the bottom wall respectively, or on the left side of the bottom wall and the left side wall, or on the left side of the bottom wall and the left side of the rear wall. The process is simple, the structure is simple, and the assembly is easy, which is the basis and is not required or limited.

[0120] Further, in the foregoing, the air inlet 12 and the air outlet 13 of the condensing air duct 1 are arranged on the top wall and the bottom wall of the condensing air duct respectively and on the same side, and the condensing plate 111 is arranged transversely in the condensing air duct 1, which divides the condensing air duct 1 into two parts transversely, and the humid air turns at the flow-through gap 114 at the free end. The transverse arrangement refers to being arranged parallel or approximately parallel to the top wall or the bottom wall.

[0121] In actual application, the air inlet 12 and the air outlet 13 can be arranged on the same side wall, such as being arranged on the bottom wall, and the condensing plate 111 can be arranged longitudinally between the air inlet 12 and the air outlet 13, the free end of the condensing plate 111 faces the top wall, and a flow-through gap 114 is left between the top wall, which can also form a U-shaped or continuous S-shaped air path in the condensing air duct 1.

[0122] Alternatively, the air inlet 12 and the air outlet 13 can be arranged on opposite side walls and on different sides, as shown in Figs. 4 and 5. In this mode, the condensing plate 111 can also be arranged longitudinally in the condensing air duct 1, and as shown in Fig. 6, the condensing plate 111 can be multiple and arranged staggered, and the fins 112 are inclined to facilitate the condensate on the fins 112 to naturally slide under the action of gravity.

[0123] The longitudinal arrangement refers to being arranged vertically from the top wall to the bottom wall, that is, being arranged in the height direction. The extension direction of the condensing plate 111 can be determined according to the arrangement positions of the air inlet 12 and the air outlet 13, such as being perpendicular to the length direction and the width direction of the condensing air duct 1, or even being arranged along the diagonal surface in the space of the condensing air duct 1, which is not required or limited.

[0124] Similarly, the air inlet and the air outlet can determine the specific positions of the air inlet 112 and the air outlet 13 of the condensing air duct 1 and the air exhaust channel 2 according to the space in the casing, the fixing requirements of other structures in the casing, and the positions of the air inlets and outlets on the casing, and determine the installation mode of the condensing plate 111 according to the positional relationship between the air inlet 112 and the air outlet 13, including but not limited to the modes described above. Adjusting the installation mode and angle of the condensing plate 111 according to the positions of the air inlet 112 and the air outlet 13 is also within the protection scope of the present application.

[0125] As shown in FIGS. 4 and 5, the top of the condensing air duct is also provided with an air exhaust channel 2. The condensing air duct 1 and the air exhaust channel 2 can be integrally formed or assembled and fixed into an integrated structure by insertion or clamping. The condensing air duct 1 and the air exhaust channel 2 are communicated through the air outlet.

[0126] As shown in FIG. 3, the air exhaust channel 2 is a nearly rectangular structure with five closed sides and one open side. The open end is the air outlet end. The bottom wall of the air exhaust channel 2 is integrally formed with the top wall of the condensing air duct 1 and extends forward (in the direction shown in FIG. 3, towards the casing) by a certain distance. During installation, the air exhaust channel 2 is connected to the air outlet on the casing by insertion. By making the air outlet end of the air exhaust channel 2 protrude from the side wall of the condensing air duct 1 by a certain distance, the condensing air duct 1 is prevented from directly contacting the casing after installation, thereby preventing the heat in the condensing air duct 1 from being conducted to the casing and causing the casing to heat up and generate condensation.

[0127] The air outlet end of the air exhaust channel 2 is arranged on the side, and the air outlet 13 is arranged on the bottom wall (the top wall of the condensing air duct 1) of the air exhaust channel 2 and is spaced apart from the air outlet end of the air exhaust channel 2 by a certain distance. The air inlet direction of the air exhaust channel 2 is perpendicular to the air outlet direction, and the air outlet direction of the air exhaust channel 2 is also perpendicular to the air inlet direction of the condensing air duct 1. This can effectively save the effective space in the casing.

[0128] In this embodiment, the air exhaust channel 2 is integrally formed with the condensing air duct 1. The bottom wall of the air exhaust channel 2 is the top wall of the condensing air duct 1. As shown in FIG. 3, the length of the bottom wall of the air exhaust channel 2 in the transverse direction (perpendicular to the air outlet direction) is greater than the length of the top wall of the condensing air duct 1 in the transverse direction. The two ends of the bottom wall of the air exhaust channel 2 protrude from the two ends of the condensing air duct 1 and hang down in an arc shape. The arc shape is smoothly connected to the arched top wall of the condensing air duct 1. The air entering the air exhaust channel 2 is sprayed onto the top wall of the air exhaust channel 2 and is reflected, thereby diffusing into the entire space, reducing the pressure, and further reducing the temperature of the air, which is then discharged from the air outlet end.

[0129] The air exhaust channel 2 is assembled and fixed with the casing. As shown in FIGS. 4 and 5, buckles 6 and / or screw columns 7 are arranged on the top wall of the air exhaust channel 2 to enable the air exhaust channel 2 to be clamped and / or screwed with the casing or other structures in the casing.

[0130] To strengthen the overall strength of the ventilation module, avoid the outer wall of the condensing air duct 1 directly contacting the cabinet or having a small distance with the cabinet, generating radiation heat conduction, a temperature insulation cavity is further arranged on both sides of the condensing air duct 1, the air is insulated or the temperature insulation cotton is filled in the temperature insulation cavity, to avoid the temperature of the condensing air duct 1 rising after heat exchange with the humid air, directly conducting the temperature to the cabinet, making the temperature of the cabinet rising, and condensation on the surface of the cabinet, and the temperature insulation cavity also has the effect of strengthening the overall strength of the condensing air duct 1.

[0131] Further, a plurality of reinforcing ribs 4 are further arranged at the top of the condensing air duct 1 (the position shown in Fig. 3), the top of the reinforcing ribs 4 is connected with each other through the transverse reinforcing ribs 5, the buckle 6 or the screw column 8 is arranged at the top of the transverse reinforcing rib 5. The reinforcing ribs 4 and the transverse reinforcing ribs 5 strengthen the strength of the top of the condensing air duct 1, and provide support for the buckle 6 and the screw column 7, and the height of the reinforcing ribs 4 and the transverse reinforcing ribs 5 is arranged according to the need of the installation space.

[0132] In the application, the ventilation module is arranged in the drum washing machine as an example to introduce the specific structure, and the ventilation module provided by the application can be arranged in any device that can generate humid air and needs internal and external ventilation, including but not limited to laundry processing equipment such as washing machines and shoe washing machines, and household appliances such as dishwashers and disinfection cabinets, and adaptive changes can be made to the shape of the ventilation module and the setting position and structure characteristics of the air inlet channel 2 and the air outlet channel according to the nature and structure characteristics of the household appliance, which are all within the protection scope of the application.

[0133] In the laundry processing equipment provided by the application, the ventilation module described above is arranged, and in the ventilation module provided by the application, no electric appliances such as motors and air blower are arranged, and no air door is arranged, in the operation process of the washing machine, the air flow between the inner drum and the outer drum is driven by the rotation of the inner drum, the flowing humid air automatically enters the ventilation module through the exhaust device, is cooled and dehumidified at the condensing air duct 1, especially in the dehydration process, the high-speed rotation of the inner drum makes a large amount of air between the inner drum and the outer drum escape through the exhaust device and the ventilation module. After the washing is completed, since no air door is arranged, even if the door body is closed, the air inside the outer drum and the air outside the cabinet can be naturally communicated through the ventilation module and the exhaust channel, and a closed space is not formed in the humid washing drum due to the closing of the door body, and bacteria are not bred. At the same time, the drainage structure is arranged at the lowest position of the condensing air duct 1, to timely drain the generated condensate water, avoid the condensate water accumulating in the condensing air duct 1 and breeding bacteria, and the drainage structure is arranged separately from the air inlet 12, to also prevent the condensate water from flowing back to the inner drum through the air inlet and the exhaust device.

[0134] After the inner cylinder stops rotating, especially the high-speed rotation at the end of dehydration, the air outside the machine shell can also enter the washing cylinder in the reverse direction under the action of the pressure difference between the inside and outside of the inner cylinder, which can accelerate the sliding speed of the condensed water on the condensing plate 1, and can dry part of the condensing plate 111 to a certain extent. To avoid introducing lint and other debris into the washing cylinder after dehydration, a filter screen can also be provided at the connection between the air outlet channel 2 and the machine shell. On the one hand, it can filter lint and other debris outside the machine shell, and on the other hand, the filter screen can also adsorb part of the water vapor, further preventing condensation from forming on the machine shell.

[0135] In summary, the ventilation module of the clothes treatment device and the clothes treatment device provided by the present application are designed and optimized on the basis of the traditional electric ventilation module, all electronic devices are cancelled, and the function of preventing the generation of condensed water is achieved. The ventilation type drum washing machine can perform the "breathing" function while bringing a substantial cost reduction space. The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent.
