The washing and drying cavity 2a, the dehumidification channel 11a and the drying channel 3 jointly form a drying circulation channel, circulation airflow can circularly flow in the drying circulation channel, and the circulation airflow firstly flows through the dehumidification channel 11a and then flows through the drying channel 3. Illustratively, the dry hot air flow in the washing and drying cavity 2a is a wet hot air flow after contacting with the wet clothes, the wet hot air flow enters the dehumidifying channel 11a through the inlet 11a 'of the dehumidifying channel 11a, and becomes a dry cold air flow after being condensed and dehumidified through the dehumidifying channel 11a, the dry cold air flow enters the drying channel 3 through the outlet 11 a' of the dehumidifying channel 11a, and becomes a dry hot air flow after being heated by the heating element, the dry hot air flow enters the washing and drying cavity 2a again, and thus the clothes are dried through the circulating air flow in the drying circulating channel.

The air exhaust channel 4 is communicated with the washing and drying cavity 2a and the outside. As the outside air flow can enter the dehumidification channel 11a through the air inlet channel 11b and then enter the washing and drying cavity 2a through the drying channel 3, the redundant air in the washing and drying cavity 2a can be discharged out of the clothes treatment equipment through the exhaust channel 4. Therefore, fresh air is provided for the washing and drying cavity 2a through the air inlet channel 11b, and redundant air is discharged through the air exhaust channel 4 so as to maintain the air pressure balance of the washing and drying cavity 2a and realize the fresh air function.

The condensing unit 1 provided by the embodiment of the present application is used in a clothes treatment device, please refer to fig. 1 to 4, the condensing unit 1 includes a condensing part 11 and a shutter 12, the condensing part 11 is formed with a dehumidification channel 11a and an air inlet channel 11b, and the air inlet channel 11b is communicated with the dehumidification channel 11a and the outside. The shutter 12 is movably disposed in the air inlet channel 11b, the shutter 12 has a conduction state for conducting the air inlet channel 11b and a blocking state for blocking the air inlet channel 11b, and the foam from the dehumidification channel 11a can drive the shutter 12 to switch from the conduction state to the blocking state.

The condensing unit 1 that this application embodiment provided, on the one hand, in moist hot air current gets into dehumidification passageway 11a, forms dry cold air current after the condensation dehumidification and flows out dehumidification passageway 11a again. Air inlet channel 11b sets up on condensation piece 11, and external air current also can send into through dehumidification passageway 11a wash and dry by the fire in chamber 2a, not only can practice thrift the runner, reduces the pipe fitting, practices thrift the installation space in the clothing treatment facility, still is convenient for improve the water content of stoving circulating air current through external air current, improves drying efficiency, improves the stoving effect. On the other hand, because the dehumidification channel 11a is communicated with the washing and drying cavity 2a, in the washing process, the foam in the washing and drying cavity 2a can enter the dehumidification channel 11a, and then enters the air inlet channel 11b through the dehumidification channel 11a and contacts the stop door 12, the acting force generated by the foam drives the stop door 12 to be switched from the conduction state to the cutoff state, so that the stop door 12 cuts the air inlet channel 11b, and the foam is prevented from overflowing from the air inlet channel 11b to the outside of the clothes treatment equipment. The acting force of the foam is utilized to drive the stop door 12 to move so as to cut off the air inlet channel 11b, the structure is simple, no complex control circuit and control structure are needed, the reliability is good, and the manufacturing cost is low.

The clothes treatment equipment provided by the embodiment of the application has the functions of washing, drying and fresh air, on one hand, in the initial stage of drying, because the clothes have high water content and are easy to have peculiar smell, the moisture content of the damp and hot airflow after contacting with the damp clothes is high, and the peculiar smell is easy to exist, at the moment, the exhaust channel 4 can exhaust the damp and hot airflow with high water content and possibly having peculiar smell, so that the problem of peculiar smell existing in the airflow is solved; when getting into and lasting the stoving stage, continuously letting in the new trend in to washing and drying chamber 2a, the circulation channel that dries simultaneously provides circulation air current stoving clothing, like this, not only can reach and do not influence indoor environment's temperature and humidity notably, reduces the influence to indoor environment, can also reach the purpose of high-efficient stoving. On the other hand, realize one-way conduction inlet air channel 11b through shutter 12, restrain the foam excessive, user experience is good.

In some embodiments, referring to fig. 1 to 3, the shutter 12 is switched from the blocking state to the conducting state when the foam releases the force on the shutter 12. Under the condition that the foam is dispersed or not, for example, after washing is finished, in the drying process or in the non-working state of the clothes treatment equipment, the foam does not exist in the air inlet channel 11b, the foam cancels the acting force on the shutter 12, so that the shutter 12 is switched from the cut-off state to the conduction state, and the outside air flow can enter the dehumidification channel 11a through the air inlet channel 11 b.

Illustratively, in one embodiment, the door 12 can remain in the open position in the event that the foam removes the force on the door 12. Like this, in the stoving in-process, shutter 12 can keep in the conducting state, and external air current can get into dehumidification passageway 11a through inlet air channel 11b, continues to wash to dry by fire the chamber 2a in to letting in new trend, dries the clothing more softly.

In one embodiment, the shutter 12 is switched from the off state to the on state under the force of gravity in the case that the foam exerts no force on the shutter 12. Referring to fig. 3, in the case that the foam is dissipated or not present, for example, after the washing is completed, during the drying process or in the non-operating state of the laundry treatment apparatus, the door 12 can move under the action of gravity to conduct the air inlet channel 11b, so that the door 12 does not need to be driven by an electric control such as a motor, and the cost is low.

In some embodiments, an elastic member, such as a spring or a leaf spring, may be further disposed in the air intake channel 11b, and the elastic member may abut against the shutter 12, and the resultant force of the elastic member and the gravity causes the shutter 12 to be maintained in the on state. The elastic member enables the shutter 12 to be more smoothly maintained in the on state. Of course, the elastic member may not be provided, and the shutter 12 may be opened and closed quickly by gravity.

In one embodiment, referring to fig. 3 and 4, the door 12 is rotatably disposed in the air intake channel 11 b. That is, the foam can drive the shutter 12 to rotate, so that the shutter 12 is switched from the on state to the off state.

In an embodiment, referring to fig. 3, 4, 9, 10, 13 and 14, one end of the shutter 12 is rotatably connected to the periphery of the air intake channel 11b, the opposite end of the shutter 12 is a free end, and when the shutter 12 is in a conduction state, the shutter 12 is spaced from the inner surface of the air intake channel 11b to conduct the air intake channel 11 b. When the shutter 12 is in the blocking state, the shutter 12 abuts against the inner surface of the air intake duct 11b to block the air intake duct 11 b. That is, the free end of the door 12 can rotate about its axis of rotation. In the on state, the shutter 12 is spaced from the inner surface of the intake duct 11b to form a spaced area through which the external air flows in the intake duct 11 b. When the shutter 12 is in the cut-off state, the shutter 12 abuts against the inner surface of the air inlet channel 11b, so that the air inlet channel 11b is cut off, and the foam cannot overflow.

In some embodiments, referring to fig. 4, when the door 12 is in the blocking state, the door 12 is in sealing contact with the inner surface of the air intake channel 11 b. Thus, there is no gap between the surface of the shutter 12 and the inner surface of the air intake channel 11b, and the air intake channel 11b is blocked, so that the foam cannot overflow.

In some embodiments, referring to fig. 1 and 3, the door 12 has a substantially flat plate-like structure, and the foam can contact the surface of the door 12 in the thickness direction to drive the door 12 to move. That is, the rotation axis of the shutter 12 may be parallel to the cross section of the air intake passage 11b, and the surface area of the shutter 12 in the thickness direction is large, so that the foam applies force to the surface of the shutter 12 in the thickness direction in a contact manner.

The specific shape of the shutter 12 is not limited, the shape of the shutter 12 is matched with the shape of the cross section of the air inlet channel 11b where the shutter 12 is located, and the shutter 12 can block the air inlet channel 11b where the shutter 12 is located. In an exemplary embodiment, referring to fig. 1, the cross-sectional shape of the air intake channel 11b where the door 12 is located is substantially quadrilateral, and the door 12 may also be substantially quadrilateral. Thus, the shutter 12 has a simple structure, is easy to manufacture, and has a low cost.

The specific manner of the rotational connection between the shutter 12 and the peripheral portion of the air intake channel 11b is not limited, and in some embodiments, for example, one of the peripheral portion of the air intake channel 11b and the shutter 12 is formed with an axial hole, and the other of the peripheral portion of the air intake channel 11b and the shutter 12 is formed with an axis, and the axis is rotationally sleeved in the axial hole. In this way, a rotational connection between the surrounding area of the air supply duct 11b and the door 12 is achieved.

In one embodiment, referring to fig. 3 and 4, the lower end 121 of the door 12 is rotatably connected to the surrounding portion of the air intake channel 11b, and the upper end 122 of the door 12 is a free end. In this way, the shutter 12 is facilitated to intercept the air intake passage 11b more quickly by the push of the foam.

It is understood that the center line of the shutter 12 in the vertical direction may be taken as a reference line, a portion below the center line of the shutter 12 in the vertical direction may be taken as a lower end 121, and a portion above the center line of the shutter 12 in the vertical direction may be taken as an upper end 122.

The upper side means a direction toward the ceiling, and the lower side means a direction opposite to the upper side.

In one embodiment, referring to fig. 3 and 4, when the door 12 is in the on state, the upper end 122 of the door 12 is inclined inward. By the design, on one hand, the size of the shutter 12 can be larger than the cross-sectional area of the air inlet channel 11b where the shutter is located, so that the shutter 12 can block the air inlet channel 11b, and the purpose of cutting off the air inlet channel 11b is achieved. On the other hand, because the setting of shutter 12 slope, under shutter 12 is in the conducting state, shutter 12 can form the interval region with between the upper surface of inlet air duct 11b, and shutter 12 can also play the effect of direction, with the quick direction inlet air duct 11b of external air current in, reduces the windage.

It should be noted that the side of the air intake channel 11b close to the outside is the outside, and the side of the air intake channel 11b close to the dehumidification channel 11a is the inside.

The inward inclination of the upper end 122 of the door 12 is not limited, and in an exemplary embodiment, referring to fig. 3 and 4, a portion of the lower surface of the air intake channel 11b protrudes upward to form a supporting member 111, the lower end 121 of the door 12 is located outside the supporting member 111, and the door 12 is obliquely supported on the supporting member 111 when the door 12 is in a conducting state. Under the supporting force of the supporting member 111, the upper end 122 of the shutter 12 is kept inclined inward, and the shutter 12 is not attached to the lower surface of the air intake duct 11b by gravity, so that the foam can push the surface of the shutter 12 in the thickness direction, and the upper end 122 of the shutter 12 is vertically moved to abut against the inner surface of the air intake duct 11b, thereby rapidly cutting off the air intake duct 11 b. Under the condition that the foam has no acting force on the shutter 12, the shutter 12 can fall under the action of gravity again until the shutter 12 contacts the support member 111 and stops falling, and the shutter 12 is obliquely supported on the support member 111 again to keep the conduction state of the conduction air inlet channel 11 b. Therefore, the acting force generated by the foam is small, the shutter 12 can be pushed to be rapidly switched to the cut-off state, and in the foam dissipation process, the shutter 12 can be switched to the conduction state under the action of gravity.

In one embodiment, referring to fig. 3 and 4, the top surface of the supporting member 111 is an inclined surface inclined outward, and when the door 12 is in a conducting state, the door 12 abuts against the inclined surface. Thus, the contact area of the shutter 12 with the supporter 111 is large so that the supporter 111 can smoothly support the shutter 12.

In one embodiment, referring to fig. 9 and 13, the upper end 122 of the door 12 is rotatably connected to the periphery of the air intake channel 11b, and the lower end 121 of the door 12 is a free end. The design is convenient for the shutter 12 to cut off the air inlet channel 11b quickly under the pushing of the foam.

In one embodiment, referring to fig. 9 and 13, a portion of the lower surface of the air inlet channel 11b protrudes upward to form a stop member 112, the door 12 is disposed at an interval inside the stop member 112, and when the door 12 is in a blocking state, the door 12 abuts against the stop member 112 to block the air inlet channel 11 b. Specifically, referring to fig. 9 and 13, the dimension of the door 12 and the stop member 112 in the vertical direction may be smaller than the dimension of the air inlet channel 11b, so that the door 12 is spaced from the lower surface of the air inlet channel 11b, and the stop member 112 is spaced from the upper surface of the air inlet channel 11b for air to flow through. Referring to fig. 10 and 14, when the foam drives the shutter 12 to move to abut against the stop member 112, the shutter 12 blocks the air inlet passage 11 b.

In one embodiment, referring to fig. 9 and 13, the door 12 can hang freely vertically under the action of gravity when the door 12 is in a natural state. Like this, in the washing process, shutter 12 can keep in the on-state under the action of gravity, and the effort that the foam produced is less can promote shutter 12 fast switch over to cutting the state, and after the washing, the foam is vanished, and shutter 12 can switch over to the on-state under the action of gravity.

It should be noted that the natural state of the shutter 12 means that the shutter 12 is not acted by the flowing outside air flow nor by the foam. For example, when the laundry treating apparatus is in a non-operating state, the shutter 12 is in a natural state.

In one embodiment, referring to fig. 9 and 10, a portion of the lower surface of the air intake channel 11b protrudes upward to form the bubble collecting member 113, the bubble collecting member 113 is disposed at an interval inside the door 12, and a space 113a is formed between the bubble collecting member 113 and the upper surface of the air intake channel 11 b. That is, the size of the bubble-collecting member 113 in the up-down direction is smaller than that of the air intake passage 11b, so that the bubble-collecting member 113 is spaced apart from the upper surface of the air intake passage 11b to form a spacing space 113 a. The foam can be gradually upwards accumulated under the action of the foam collecting piece 113, the foam is gradually accumulated to the position of the stop door 12 through the interval space 113a, and the space between the foam collecting piece 113 and the stop door 12 is relatively narrow, so that the foam can be rapidly filled in the space between the foam collecting piece 113 and the stop door 12, and the stop door 12 is rapidly pushed to move towards the stop piece 112 so as to rapidly cut off the air inlet channel 11 b.

It will be appreciated that the door 12 may be prevented from contacting the bubble-collecting member 113 when the door 12 is impacted by the outside air flow by controlling the size of the bubble-collecting member 113 in the up-down direction, the distance between the bubble-collecting member 113 and the door 12, and/or the flow rate of the outside air flow. For example, when the size of the bubble-collecting member 113 in the up-down direction is small, and the lower end 121 of the shutter 12 is deflected toward the bubble-collecting member 113, the lower end 121 of the shutter 12 is misaligned with the bubble-collecting member 113, so that the shutter cannot contact the bubble-collecting member 113. For another example, when the distance between the bubble trap 113 and the shutter 12 is large and the lower end 121 of the shutter 12 deflects toward the bubble trap 113, the lower end 121 of the shutter 12 is misaligned with the bubble trap 113, so that the shutter cannot contact the bubble trap 113. For another example, when the flow rate of the outside air flow is less than the set value, the deflection angle of the shutter 12 is small, and the lower end 121 of the shutter 12 is misaligned with the bubble-collecting member 113, so that the shutter cannot contact the bubble-collecting member 113.

It should be noted that the set value can be designed according to actual requirements, such as the weight of the door 12, and the application is not limited herein.

In one embodiment, referring to fig. 4, 10 and 14, the air inlet channel 11b is located between the inlet 11 a' of the dehumidification channel 11a and the outlet 11a ″ of the dehumidification channel 11 a. Thus, the outside air flow and the air flow in the dehumidification channel 11a are more uniformly mixed to form a mixed air flow, and then the mixed air flow flows out through the outlet 11 a' of the dehumidification channel 11 a.

In an embodiment, referring to fig. 4, 10 and 14, the condensing element 11 is formed with a cooling medium channel 11c communicated with the dehumidifying channel 11a, and the cooling medium channel 11c is located between an inlet 11 a' of the dehumidifying channel 11a and the air intake channel 11 b. During the drying process, wet hot air flow enters the dehumidification channel 11a from the inlet 11a ', the refrigerant from the refrigerant channel 11c enters the dehumidification channel 11a, the wet hot air flow is firstly contacted with the refrigerant for heat exchange and dehumidification to form dry cold air flow, the dry cold air flow is mixed with external air flow from the air inlet channel 11b to form mixed air flow, and the mixed air flow flows out through the outlet 11 a'. Like this, the water content of mist is low and the amount of wind is big, can not only dry the clothing more high-efficiently, can also avoid the new trend to influence condensation efficiency.

The type of the cooling medium is not limited, and the cooling medium includes, but not limited to, water. For example, the cold medium can be low-temperature water liquid, the wet hot air flow comprises hot air and gaseous water, so that the wet hot air is directly contacted with the low-temperature water liquid, the low-temperature water liquid absorbs heat of the wet hot air flow, the temperature of the low-temperature water liquid is increased but not enough to be vaporized, and the gaseous water in the wet hot air flow is condensed into water drops after being cooled.

In this way, the laundry may be washed by the rotation of the washing and drying cylinder to move the laundry and the water flow, for example, the laundry may be cleaned, rinsed, and dehydrated by the rotation of the washing and drying cylinder. The washing and drying drum can also be rotated when drying the clothes, so that the clothes can be dried more uniformly and quickly.

In some embodiments, referring to fig. 5, 6, 11 and 12, the tub assembly 2 may further include an outer tub 21 disposed outside the washing and drying tub, a circumferential surface of the washing and drying tub may form a circulation port, the outer tub 21 may be capable of holding water and draining water, and the outer tub 21 may be fixed. Both water and air can flow between the washing and drying cylinder and the outer cylinder 21 through the flow opening. The outer cylinder 21 is kept fixed, so that structures such as the drying tunnel 3, the condensing device 1 and the like can be conveniently arranged outside the outer cylinder 21, and the assembly difficulty is reduced.

In some embodiments, referring to fig. 7 and 12, the inlet 11 a' of the dehumidifying channel 11a and the exhaust channel 4 are communicated with the outer tub 21. Both the condensed water and the refrigerant from the dehumidification passage 11a can enter the outer tub 21 through the inlet 11 a' of the dehumidification passage 11a, and then be discharged to the outside of the laundry treatment apparatus through the drain port of the outer tub 21. The air flow in the washing and drying cavity 2a can also flow out of the washing and drying cylinder through the flow opening and then is exhausted through the exhaust channel 4.

In some embodiments, referring to fig. 5, 6, 11 and 12, the axis of the barrel assembly 2 may be horizontal. In other words, the laundry treating apparatus may be a rolling type laundry treating apparatus. Illustratively, the axes of the outer tub 21 and the washing tub are both in the horizontal direction, and the washing tub and the outer tub 21 are both open toward the front side, so that the user can put laundry into or take laundry out of the washing chamber 2a through the front side openings of the washing tub and the outer tub 21.

Front means a side facing the user, and rear means a side facing away from the user.

In some embodiments, the laundry treating apparatus includes a door body capable of opening the front-side opening of the outer tub 21 or sealingly closing the front-side opening of the outer tub 21. Thus, when the laundry treating apparatus is required to be used or after use, the front opening of the outer tub 21 can be opened by the door body to take in and take out the laundry. In the washing or drying process, the door body hermetically closes the front opening of the outer tub 21 to prevent water, gas, or the like from flowing out of the front opening of the outer tub 21.

In some embodiments, referring to fig. 5 to 12, the axis of the tub assembly 2 is along a horizontal direction, the drying tunnel 3 is disposed on the upper surface of the outer tub 21, the air outlet of the drying tunnel 3 is communicated with the top portion of the front surface of the outer tub 21, the condensing device 1 is disposed on the upper portion of the rear surface of the outer tub 21, and the inlet 11 a' of the dehumidifying channel 11a is communicated with the rear portion of the outer tub 21. The hot and humid air flow in the washing and drying cavity 2a enters the dehumidifying channel 11a from the upper side of the rear part, the dry and hot air flow enters the washing and drying cavity 2a from the top side of the front part, the positions of the air outlet of the drying channel 3 and the inlet 11 a' of the dehumidifying channel 11a are higher, and water liquid and/or foam and the like are prevented from entering the drying channel 3 and the dehumidifying channel 11a to a certain degree. Under the condition that the foam quantity is large, for example, under the condition that the addition amount of detergent is too large, the foam can fill the whole washing and drying cavity 2a, too much foam inevitably enters the dehumidification channel 11a, the foam is gradually filled into the air inlet channel 11b, at the moment, the foam pushes the stop door 12 to be switched to a cut-off state, and the stop door 12 can effectively prevent the foam from overflowing.

It should be noted that, in the embodiment of the present application, the top is the same as the upper direction, and the bottom is the same as the lower direction.

For example, in some embodiments, referring to fig. 6, the wind mixing portion 114 is disposed above the outer cylinder 21, and the dehumidifying portion 115 is attached to the rear surface of the outer cylinder 21. In this way, the condensation device 1 can be more stably mounted on the outer tub 21, and the condensation device 1 can be prevented from occupying an excessive installation space.

In some embodiments, referring to FIGS. 5 and 6, the axis of the tub assembly 2 is in a horizontal direction, and the exhaust duct 4 is formed at the top of the outer tub 21. Further, the exhaust duct 4 is located on the rear side of the top of the outer tub 21. On one hand, the position of the air exhaust channel 4 is higher, and the water liquid and/or the foam in the washing and drying cavity 2a are difficult to contact the air exhaust channel 4. On the other hand, the air exhaust channel 4 is far away from the air outlet of the drying tunnel 3, so that the dry hot air flow is prevented from being exhausted from the air exhaust channel 4 to a certain extent.

In some embodiments, the laundry treating apparatus includes a wind wheel provided in the drying tunnel 3. The wind wheel is used for driving airflow to flow. On one hand, the wind wheel rotates to form negative pressure in the drying channel 3 so as to drive the airflow in the washing and drying cavity 2a and the outside airflow to enter the dehumidification channel 11 a. On the other hand, the wind wheel is arranged in the drying channel 3, so that the wind wheel is prevented from occupying the space of the dehumidification channel 11a, the structure of the condensing device 1 is simplified, the flow field in the dehumidification channel 11a is more stable, and the wind resistance is small.

In some embodiments, the heater is located downstream of the wind wheel in the direction of airflow. That is, the mixed air flows through the wind wheel and then through the heater. In this way, heated dry hot air flow is prevented from contacting the wind wheel.

In some embodiments, in the washing process, the wind wheel, the heater and the condensing device 1 can be in a non-working state, namely, the wind wheel does not rotate, the heater does not heat, and the condensing device 1 does not introduce a refrigerant and introduce fresh air. The water flow in the washing and drying chamber 2a moves with the laundry to wash the laundry.

In some embodiments, in the drying process, the wind wheel, the heater and the condensing device 1 can be in a working state, namely, the wind wheel rotates, the heater heats, and the condensing device 1 is introduced with a refrigerant and introduces fresh air.
