Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims priority to Chinese Patent Application Nos. 201920406286.1 and 201910238660.6, field on March 27, 2019 , the entire contents of which are incorporated herein by reference.

FIELD

This application relates to the technical field of clothes treatment, and in particular to a clothes treatment device such as a clothes dryer and an integrated washer-dryer.

BACKGROUND

For an existing integrated washer-dryer, based on heat exchange between an outer drum and the outside air, hot and humid air in the drum condenses on a drum wall to form condensed water, thereby achieving the effect of clothes drying. However, since there is a small temperature difference between the outer drum and the air in the drum, even if a blower is added between the outer drum and a case, the temperature difference between the outer drum and the air in the drum cannot be effectively reduced.
A related art discloses a cycle + suction + discharge washing machine. During circulation of an airflow, part of the outside air can be sucked in through a suction opening, and then part of hot and humid air can be discharged from a discharge opening; however, at an initial stage of drying, the blower will suck in air from the outside, and then discharge part of air out of the drum, thus resulting in a slow heating-up in the initial stage; after the temperature rises in a later stage, still only a small part of the hot and humid air in the drum is discharged, and most of the hot and humid air still participates in the internal circulation. Therefore, the drying efficiency is still not high, and the energy consumption is still large.
For this reason, another related art discloses a washer-dryer with a condenser tube, but it still has the following shortcomings:

(1) Since the structure of the washer-dryer is more complicated than that of a dryer, the washer-dryer with a condenser tube (water-cooling) at the rear of the outer drum can have better drying efficiency, but it will inevitably make sacrifices in the volume of the drum, that is, it will affect the capacity of the clothes.
(2) Condensation is implemented in a water-cooling way, which causes waste of water and is not conducive to the reduction of energy consumption.
(3) Although the washer-dryer can achieve rapid temperature rise in the initial stage of drying, when the external circulation is required to discharge the hot air in the later stage, both a suction opening and a discharge opening are located on a circulation pipe, so that the hot and humid air just discharged will be sucked in immediately, which is not conducive to the improvement of drying efficiency.

SUMMARY

The present disclosure is intended to solve at least one of the technical problems existing in the prior art. In view of this, an objective of the present disclosure is to provide a clothes treatment device which has high drying efficiency, low energy consumption and a large-capacity clothes treatment chamber.

Compared with a same volume of a washer-dryer with a condenser tube in the related art, the clothes treatment device according to the embodiment of the present disclosure omits the condenser structure; in this way, the volume of the drum assembly can be increased, thereby increasing the capacity of the clothes treatment chamber; moreover, in the process of drying clothes, condensing water is not required, which saves water resources and reduces energy consumption. In the present disclosure, the heating member is mounted in the air channel assembly and the damper which can be switched between the first position and the second position is provided, so that the position of the damper can be switched according to the drying process; for example, in an initial stage of drying, the damper is switched to the first position, so that outside air enters the clothes treatment chamber and quickly takes away moisture of clothes; and in the middle and late stages of drying, the air damper is switched to the second position to increase the temperature in the clothes treatment chamber, thereby providing a drying effect. In another example, the damper is switched to the second position in the initial stage of drying to quickly increase the temperature inside the drum assembly; and in the middle and later stages of drying, the damper is switched to the first position to increase the discharge speed of hot and humid air. In this way, the switch of different drying modes is realized, thus taking into account the energy consumption and drying efficiency, and achieving high capacity, low energy consumption and high efficiency.

DETAILED DESCRIPTION

Embodiments of the present disclosure will be described below in detail. Examples of the embodiments are illustrated in the accompanying drawings, where the same or similar reference numerals throughout the specification refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be illustrative only and are not to be construed as limiting the scope of the present disclosure.
A clothes treatment device 100 according to an embodiment of the present disclosure will be described below with reference to FIGS. 1 to 6. The clothes treatment device 100 here may be configured as a clothes dryer or a washer-dryer.
As show in FIGS. 1 to 6, the clothes treatment device 100 according to the embodiment of the present disclosure includes a drum assembly 10 defining a clothes treatment chamber 121 therein, the drum assembly 10 has a first air inlet 101, a first air outlet 102 and a second air outlet 103 that are all in communication with the clothes treatment chamber 121, and both the first air outlet 102 and the second air outlet 103 are provided at an upper part of a side wall of the drum assembly 10. In this embodiment, an axial direction of the drum assembly 10 extends in a front-rear direction or extends obliquely relative to the front-rear direction.
Further, the clothes treatment device 100 further includes a clothes drying assembly 20. The clothes drying assembly 20 includes an air channel assembly, a heating member 22 and a blower 23 configured to guide air to flow. The air channel assembly has an air channel 2101, and the air channel has a first ventilation opening 2102, a second air inlet 2103 and an air channel outlet 2104. Both the first ventilation opening 2102 and the second air inlet 2103 can serve as an air channel inlet of the air channel 2101. The first ventilation opening 2102 is in communication with the first air outlet 102, the second air inlet 2103 is in communication with the outside, and the air channel outlet 2104 is in communication with the first air inlet 101. The air channel 2101 is provided inside with a damper 241 which can be switched between the first position and the second position.
The heating member 22 is arranged in the air channel 2101 to heat air in the air channel 2101. In order to effectively utilize the space in the air channel 2101, improve drying efficiency, and increase a contact area between airflow and the heating member 22, the heating member 22 is configured as a serpentine heating elbow.
In a state where the damper 241 is switched to the first position, the damper 241 closes the first air outlet 2102, that is, closes the first air outlet 102, and opens the second air inlet 2103 at the same time, so that the second air inlet 2103 and the air channel outlet 2104 are in communication. Outside air is guided by the blower 23 to enter the air channel 2101 from the second air inlet 2103. Hot air heated by the heating member 22 flows into the clothes treatment chamber 121 through the air channel outlet 2104 and the first air inlet 101. The hot air flows through wet clothes and is then discharged from the second air outlet 103 to the outside.
In a state where the damper 241 is switched to the second position, the damper 241 closes the second air inlet 2103 and opens the first ventilation opening 2102 at the same time, that is, opens the first air outlet 102, so that the first ventilation opening 2102 and the air channel outlet 2104 are in communication. Humid air in the clothes treatment chamber 121 is guided by the blower 23 to enter the air channel 2101 from the first ventilation opening 2102. Hot air heated by the heating member 22 flows into the clothes treatment chamber 121 through the air channel outlet 2104 and the first air inlet 101. The hot air flows through wet clothes and is then discharged from the first air outlet 102 and flows in the air channel 2101. The same operation is carried out round and round.
Compared with a same volume of a washer-dryer with a condenser tube in the related art, the clothes treatment device 100 according to the embodiment of the present disclosure omits a condenser structure; in this way, the volume of the drum assembly 10 can be increased, thereby increasing the capacity of the clothes treatment chamber 121; moreover, in the process of drying clothes, condensing water is not required, which saves water resources and reduces energy consumption.
In addition, according to the present disclosure, the heating member 22 is mounted in the air channel assembly and the damper 241 which can be switched between the first position and the second position is provided, so that the position of the damper 241 can be switched according to the drying process; for example, in an initial stage of drying, the damper 241 is switched to the first position, so that outside air enters the clothes treatment chamber 121 and quickly takes away moisture of clothes; and in the middle and late stages of drying, the damper 241 is switched to the second position to increase the temperature in the clothes treatment chamber 121, thereby providing a drying effect. In another example, the damper 241 is switched to the second position in the initial stage of drying and switched to the first position in the middle and later stages of drying; in this way, the switch of different drying modes is realized, thus taking into account the energy consumption and drying efficiency, and achieving high capacity, low energy consumption and high efficiency.
According to an embodiment of the present disclosure, the damper 241 is switched between the first position and the second position through the drive of a damper motor 242. For example, the damper motor 242 can drive the damper to pivotally rotate between the first position and the second position.
As shown in FIGS. 4 and 5, in this embodiment, in order to ensure higher working efficiency in a working mode when the damper 241 is switched to the first position, a flow area S1 of the second air inlet 2103 is set to be greater than 3000 mm², thus achieving a better dehumidification and cooling effect in the clothes treatment chamber 121.
In order to ensure higher working efficiency in a working mode when the air door 241 is switched to the second position, a flow area S2 of the second air outlet 103 is set to be greater than 1500 mm², and a flow area S3 of the first air outlet 102 is set to be greater than 3000 mm². In this way, the temperature of the drum assembly 10 can be quickly increased, thereby increasing the drying speed.
According to an embodiment of the present disclosure, in an axial direction of the drum assembly 10, the first air inlet 101 is located at a front part of the drum assembly 10, and the first air outlet 102 and the second air outlet 103 located at a rear part of the drum assembly 10.
In this embodiment, the axial direction of the drum assembly 10 extends in the front-rear direction, a front end surface of the drum assembly 10 has a clothes access opening, and the first air inlet 101 is provided at a top of an outer peripheral wall of the drum assembly 10 adjacent to the clothing access opening, or the first air inlet 101 is provided at a top of a door seal of the drum assembly 10. The first air outlet 102 and the second air outlet 103 are provided at a top of an outer peripheral wall of the drum assembly 10 adjacent to a rear end surface of the drum assembly 10, that is, the first air outlet 102 and the second air outlet 103 are provided at a position in the middle-rear part of the drum assembly 10.
Thus, the first air inlet 101, the first air outlet 102, and the second air outlet 103 are arranged in the above manner, which can increase a distance between the first ventilation opening 2102 and the air channel outlet 2104 and a distance between the second air inlet 2103 and the air channel outlet 2104. In this way, the flowing time of moist air (discharged from the clothes treatment chamber 121) in the air channel 2101 can be increased, the heating time of the heating member 22 to the airflow is prolonged, and the moist air just discharged can be prevented from being sucked in immediately, which is beneficial to improving the drying efficiency.
In some embodiments, in the axial direction of the drum assembly 10, the second air outlet 103 is provided at the front of the first air outlet 102, that is, the distance between the first air outlet 102 and the first air inlet 101 is increased. Therefore, the length of an internal circulation path of the airflow is prolonged, and the heating time of the heating member 22 to the airflow inside the air channel is prolonged, thereby improving the drying efficiency.
As shown in FIGS. 4 and 5, according to an embodiment of the present disclosure, the second air inlet 2103 and the second air outlet 103 are arranged in the circumferential direction of the drum assembly 10 and spaced apart, and the second air inlet 2103 and the second air outlet 103 are respectively located on two sides of an imaginary vertical plane Y passing through the central axis of the drum assembly 10.
As a result, the position of the drum assembly 10 in the circumferential direction is effectively used to ensure that the second air inlet 2103 and the second air outlet 103 are separated by a certain distance. In a working mode where the damper 241 is switched to the first position, the clothes treatment device 100 can prevent hot and humid air, discharged from the clothes treatment chamber 121, from being sucked into the air channel 2101 again, which is beneficial to improving the efficiency of drying clothes.
According to an embodiment of the present disclosure, the damper 241 is rotatably provided on the air channel assembly. In this embodiment, the damper motor 242 is connected to a rotating shaft of the damper 241, thereby driving the damper 241 to rotate between the first position and the second position. When the damper 241 rotates to the first position, the damper 241 extends along a horizontal plane to close the first ventilation opening 2102; when the damper 241 rotates to the second position, the damper 241 extends along a vertical surface to close the second air inlet 2103. The structure and control are simple.
According to an embodiment of the present disclosure, the drum assembly 10 includes an outer drum 11 and an inner drum 12. The inner drum 12 is rotatably provided in the outer drum 11 and extends along an axial direction of the outer drum 11. The inner drum 12 defines a clothes treatment chamber 121 in communication with a gap between the outer drum 11 and the inner drum 12.
Both the first air outlet 102and the second air outlet 103 are provided at an upper part of a side wall of the outer drum 11 and are in communication with the clothes treatment chamber 121 through the gap.
In a state where the damper 241 is switched to the first position, outside air is guided by the blower 23 to enter the air channel 2101 from the second air inlet 2103. Hot air heated by the heating member 22 flows into the clothes treatment chamber 121 through the air channel outlet 2104 and the first air inlet 101, and then enters into the clothes treatment chamber 121 to dry clothes, and finally is discharged to the outside through the second air outlet 103. The same operation is carried out round and round.
In a state where the damper 241 is switched to the second position, humid air in the clothes treatment chamber 121 is guided by the blower 23 to enter the air channel 2101 from the first ventilation opening 2102. Hot air heated by the heating member 22 enters the gap through the air channel outlet 2104 and the first air inlet 101, and then flows into the clothes treatment chamber 121 to dry the clothes. Finally, the hot air flows through wet clothes and is then discharged from the first air outlet 102 and flows in the air channel2101. The same operation is carried out round and round.
In some embodiments, the first air inlet 101 is provided on a front edge of the outer drum 11 or a door seal on the outer drum 11. By arranging the first air inlet 101 on the front edge of the outer drum 11, the length of the air channel 2101 can be increased, thereby improving the drying efficiency; by arranging the first air inlet 101 on the door seal on the outer drum 11, the length of the air channel 2101 can be increased and the drying efficiency is accordingly improved on the one hand, and on the other hand, there is no need to form holes in the outer drum 11, which simplifies the structure and processing procedures of the outer drum 11 and reduces the cost.
In some embodiments, the air channel assembly includes an air channel shell 21 mounted at the top of the outer drum 11, and an inner cavity of the air channel shell 21 is in communication with the first air inlet 101. In this embodiment, the air channel shell 21 is mounted at the top of the outer drum 11, at least a part of the air channel shell 21 extends along the axial direction of the drum assembly 10, and the air channel shell 21 defines a part of the air channel 2101 therein.
Further, the air channel assembly further includes a connection seat 214 provided between the air channel shell 21 and the drum assembly 10. The inner cavity of the air channel shell 21 is in communication with the first air outlet 102 through the inner cavity of the connection seat 214. The connection seat 214 defines the other part of the air channel 2101. The second air inlet 2103 and the damper 241 are provided on the connection seat 214.
Thus, by providing the connection seat 214, the air channel shell 21 can be supported, the top space of the outer drum 11 can be effectively used to facilitate communication with the outside, and a carrier is also provided for mounting the second air inlet 2103 and the damper 241.
In some examples, the damper 241 is provided in the inner cavity of the connection seat 214, and the second air inlet 2103 is provided on the side of the connection seat 214.
