Description

Technical Field

[0001] The utility model relates to the technical field of drying washing machines, in particular to a condenser structure with a switchable air duct, and also discloses a clothes drying device with a switchable air duct. Background Art

[0002] The condensing dryer heats the air in the air duct through a heater. The hot and dry air flows through the inner barrel, passes through the clothes, takes away the moisture and becomes hot and humid air. Then, the hot and humid air passes through the condenser to separate the water in it, and finally returns to the heater for recycling. At present, the condensing dryers on the market adopt a closed air duct system. The moisture baked out condenses into water through the condenser. The gas in the air duct does not exchange gas with the outside world, only heat exchange. As the drying process continues, the drying efficiency of the condenser decreases significantly, resulting in the clothes still feeling damp after drying.

[0003] Chinese Patent CN104514136A proposes a condensing dryer with a damper switch, including a drying air duct, which is sequentially connected by a drum, a drum air outlet, a front air duct, a condenser, a rear air duct, and a drum air inlet; the front air duct is provided with a first damper for switching the connection between the front air duct and the external environment and the connection between the front air duct and the drying air duct. The rear air duct is provided with a second damper for connecting and disconnecting the rear air duct from the external environment. The first damper is arranged on the front air duct near the inlet end side of the condenser; a drying fan for driving the drying air to circulate is arranged on the rear air duct near the condenser side, and the second damper is arranged at the air inlet end of the drying fan.

[0004] When the above-mentioned prior art opens / closes the condenser, it is necessary to simultaneously close / open the first damper and the second damper to make the drying air duct a closed / open circulating air duct; two dampers require two sets of control systems, and the overall structure is relatively complex and the cost is relatively high. Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a condenser structure with a switchable air duct and a clothes drying device with reasonable structure and flexible control of whether the air flow passes through the condenser in view of the defects and deficiencies of the prior art.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] A switchable air duct condenser structure according to the present utility model includes a housing and a condenser. An air inlet and an air outlet are provided on the housing. A first chamber, a second chamber, a third chamber, a fourth chamber and a movable partition are arranged inside the housing. The air inlet and the air outlet are respectively communicated with the first chamber and the fourth chamber, and the air inlet and the air outlet are respectively communicated with the circulation air duct of the dryer. The condenser passes through the second chamber and the third chamber.

[0008] The movable partition can move inside the housing. When the movable partition is arranged between the first chamber and the fourth chamber, the air inlet, the first chamber, the second chamber, the third chamber, the fourth chamber and the air outlet are sequentially communicated to establish a condensation air duct. The air flow entering the housing is cooled by the condenser, and the water vapor carried in the air flow condenses to achieve dehumidification.

[0009] When the movable partition is arranged between the first chamber and the second chamber, the air flow cannot enter the second chamber. The air inlet, the first chamber, the fourth chamber and the air outlet are sequentially communicated to establish a drying air duct. The air flow entering the housing does not pass through the condenser and returns to the circulation air duct of the dryer to participate in drying.

[0010] The switching between the drying air duct and the condensation air duct is realized by one movable partition. The structure is simple and the cost is low. It can improve the drying and dehumidification efficiency of the dryer and is beneficial to the promotion and sales of dryer products.

[0011] According to the above solution, the first chamber, the second chamber, the third chamber and the fourth chamber are arranged in a "field" shape inside the housing. The first chamber and the second chamber are adjacent to form a first passage opening therebetween, and the first chamber and the fourth chamber are adjacent to form a second passage opening therebetween. The movable partition can be used to cover the first passage opening or the second passage opening. The movable partition moves between the first passage opening and the second passage opening, thereby blocking the passage between the first chamber and the second chamber / between the first chamber and the fourth chamber, so that the air flow passes through or does not pass through the condenser, and the switching between the drying air duct and the condensation air duct is realized.

[0012] According to the above solution, the movable partition is rotatably connected to the housing through a rotating shaft, so that the movable partition can cover the first passage opening or the second passage opening. Further, the first passage opening and the second passage opening are adjacent and the opening directions thereof form a 90° included angle. The movable partition can reciprocally rotate inside the housing through the rotating shaft, so as to cover the first passage opening or the second passage opening, block the passage between the first chamber and the second chamber / between the first chamber and the fourth chamber, so that the air flow passes through or does not pass through the condenser, and the switching between the drying air duct and the condensation air duct is realized.

[0013] According to the above solution, a motor is provided on the housing, and the output shaft of the motor is connected to the rotating shaft to drive the movable partition to move between the first channel opening and the second channel opening. The first channel opening and the second channel opening are equivalent to two side walls of the first chamber, and the rotating shaft is rotatably provided at the intersection of the two side walls. Furthermore, the rotating shaft and the movable partition are driven by the motor to rotate 90°, so that the movable partition covers the first channel opening or the second channel opening, realizing the switching between the drying air duct and the condensation air duct.

[0014] According to the above solution, the housing includes a bottom plate and an upper cover, and the upper cover and the bottom plate are paired and connected to form a first chamber, a second chamber, a third chamber, and a fourth chamber therebetween; the air inlet and the air outlet are provided on the upper cover to communicate with the first chamber and the fourth chamber respectively. The bottom plate and the upper cover are paired and connected to form a hollow housing, and the first chamber, the second chamber, the third chamber, and the fourth chamber are arranged in a "field" shape in the housing. It can be understood that the third chamber and the fourth chamber are normally open and connected, and the second chamber and the third chamber are also normally open and connected.

[0015] Among them, the on-off of the first channel opening between the first chamber and the second chamber is controlled by the movable partition, and the on-off of the second channel opening between the first chamber and the fourth chamber is controlled by the movable partition.

[0016] Furthermore, the second channel opening can also be provided between the third chamber and the fourth chamber.

[0017] According to the above solution, a shaft hole is provided on the bottom plate, and the rotating shaft is matched with the shaft hole so that the movable partition is rotatably connected to the bottom plate. The motor is fixedly arranged on the bottom plate so that the output shaft is connected to the rotating shaft. The rotating shaft and the shaft hole are matched, so that the movable partition can rotate between the bottom plate and the upper cover. The motor drives the movable partition to rotate 90° clockwise or counterclockwise to cover the first channel opening or the second channel opening. The switching action of the movable partition is highly flexible and the overall cost is lower.

[0018] According to the above solution, an assembly port is provided on the bottom plate, a skirt plate is provided on the condenser, and the condenser is inserted through the assembly port and arranged in the second chamber and the third chamber. The skirt plate is placed on the bottom plate, and a sealing ring is provided between the skirt plate and the bottom plate. The condenser is placed on the bottom plate through the skirt plate, so that the upper part of the condenser is arranged in the second chamber and the third chamber between the upper cover and the bottom plate. The skirt plate ensures the sealing performance of the assembly port through the sealing ring.

[0019] According to the above solution, the upper part of the condenser has a number of heat dissipation fins, and the number of heat dissipation fins are arranged at intervals to form a number of condensation grooves in the second chamber and the third chamber of the housing respectively. It can be understood that the upper end surface of the condenser can abut against the upper cover, and the number of condensation grooves enables the first chamber, the second chamber, the third chamber and the fourth chamber to be connected in sequence. When the air flow passes through the number of condensation grooves, it is cooled to form condensed water, thereby reducing the humidity of the air flow discharged from the air outlet.

[0020] According to the above solution, a fifth chamber is further provided in the housing. The first chamber is connected to the fifth chamber through a number of condensation grooves in the second chamber, and the fourth chamber is connected to the fifth chamber through a number of condensation grooves in the third chamber. It can be understood that both the third chamber and the fourth chamber are internal spaces of the housing, and the condenser is arranged in the housing. A part of the space is left on one side of the condenser to form the fifth chamber. The fifth chamber is adjacent to the second chamber and the third chamber respectively, so that the second chamber and the third chamber are connected to each other.

[0021] According to the above solution, a blower is provided on the housing. The blower is installed on the assembly port and is fixedly connected to the bottom plate. When the movable partition covers the first channel port, the air flow passes through the condenser, and the blower performs forced air cooling on the lower part of the condenser, thereby improving the dehumidification efficiency of the condenser.

[0022] A clothes drying device with a switchable air duct includes a drying drum, a circulating air duct and a condenser structure with a switchable air duct.

[0038] The movable partition 3 is rotatably connected to the housing 1 through a rotating shaft 31, so that the movable partition 3 can cover the first passage opening 17 or the second passage opening 18. Further, the first passage opening 17 and the second passage opening 18 are adjacently arranged, and the opening directions of the two are arranged at an included angle of 90°. The movable partition 3 can reciprocally rotate in the housing 1 through the rotating shaft 31, so as to cover the first passage opening 17 or the second passage opening 18, blocking the passage between the first chamber 13 and the second chamber 14 / between the first chamber 13 and the fourth chamber 16, so that the air flow passes through or does not pass through the condenser 2, realizing the switching between the drying air duct and the condensation air duct.

[0039] A motor 4 is provided on the housing 1, and the output shaft of the motor 4 is connected to the rotating shaft 31 to drive the movable partition 3 to move between the first channel opening 17 and the second channel opening 18. The first channel opening 17 and the second channel opening 18 are equivalent to two side walls of the first chamber 13, and the rotating shaft 31 is rotatably provided at the intersection of these two side walls. Furthermore, the rotating shaft 31 and the movable partition 3 are driven by the motor 4 to rotate 90°, so that the movable partition 3 covers the first channel opening 17 or the second channel opening 18, realizing the switching between the drying air duct and the condensation air duct.

[0040] The housing 1 includes a bottom plate 21 and an upper cover 22.

It can be understood that the third chamber 15 and the fourth chamber 16 are normally open and connected, and the second chamber 14 and the third chamber 15 are also normally open and connected.

[0041] Among them, the first channel opening 17 between the first chamber 13 and the second chamber 14 is controlled by the movable partition 3 to be opened and closed, and the second channel opening 18 between the first chamber 13 and the fourth chamber 16 is controlled by the movable partition 3 to be opened and closed.

[0042] Furthermore, the second channel opening 18 can also be provided between the third chamber 15 and the fourth chamber 16.

[0043] A shaft hole 23 is provided on the bottom plate 21. The rotating shaft 31 is matched with the shaft hole 23 so that the movable partition 3 is rotatably connected to the bottom plate 21, and the motor 4 is fixedly arranged on the bottom plate 21 so that the output shaft is connected to the rotating shaft 31. The rotating shaft 31 and the shaft hole 23 are matched, so that the movable partition 3 can rotate between the bottom plate 21 and the upper cover 22. The motor 4 drives the movable partition 3 to rotate 90° clockwise or counterclockwise to cover the first channel opening 17 or the second channel opening 18.

[0044] An assembly port 24 is provided on the bottom plate 21, a skirt plate 25 is provided on the condenser 2, and the condenser 2 is inserted from the assembly port 24 and arranged in the second chamber 14 and the third chamber 15. The skirt plate 25 is placed on the bottom plate 21, and a sealing ring 26 is provided between the skirt plate 25 and the bottom plate 21. The condenser 2 is placed on the bottom plate 21 through the skirt plate 25, so that the upper part of the condenser 2 is arranged in the second chamber 14 and the third chamber 15 between the upper cover 22 and the bottom plate 21. The skirt plate 25 ensures the sealing performance of the assembly port 24 through the sealing ring 26.

[0045] The upper part of the condenser 2 has a plurality of heat sinks, which are arranged at intervals to form a plurality of condensation grooves 27 in the second chamber 14 and the third chamber 15 of the housing 1. It can be understood that the upper end surface of the condenser 2 can contact the upper cover 22, and the plurality of condensation grooves 27 can connect the first chamber 13, the second chamber 14, the third chamber 15 and the fourth chamber 16 in sequence, and the airflow is cooled to form condensed water when passing through the plurality of condensation grooves 27, so that the humidity of the airflow discharged from the air outlet 12 is reduced.

[0046] The shell 1 is also provided with a fifth chamber 19, the first chamber 13 is connected to the fifth chamber 19 through a plurality of condensation grooves 27 in the second chamber 14, and the fourth chamber 16 is connected to the fifth chamber 19 through a plurality of condensation grooves 27 in the third chamber 15. It can be understood that the third chamber 15 and the fourth chamber 16 are both internal spaces of the shell 1, the condenser 2 is arranged in the shell 1, and a part of the space is reserved on one side of the condenser 2 to form the fifth chamber 19, and the fifth chamber 19 is adjacent to the second chamber 14 and the third chamber 15 respectively, so that the second chamber 14 and the third chamber 15 are connected to each other.

[0047] The housing 1 is provided with a fan 28, which is mounted on the assembly opening 24 and fixedly connected to the bottom plate 21. When the movable partition 3 is sealed on the first channel opening 17, air flows through the condenser 2, and the fan 28 performs forced air cooling on the lower part of the condenser 2, thereby improving the dehumidification efficiency of the condenser 2.

[0048] like Figures 5-6 As shown, a clothes drying device with switchable air duct described in the utility model comprises a drying drum 5, a circulating air duct 51 and a switchable air duct condenser structure, wherein the drying drum 5 is respectively connected to the air inlet 11 and the air outlet 12 of the switchable air duct condenser structure through the circulating air duct 51, a blower 52 and a heating element 53 are arranged in the circulating air duct 51, a vent 54 is arranged on the circulating air duct 51, and a damper 55 is covered on the vent 54, and the damper 55 is linked to the movable partition 3 through a transmission mechanism; when the motor 4 drives the movable partition 3 to cover the first channel opening 17, the transmission mechanism drives the damper 55 to open the vent 54; when the motor 4 drives the movable partition 3 to cover the second channel opening 18, the transmission mechanism drives the damper 55 to close the vent 54.

[0049] Specifically, the transmission mechanism can be a device / element that can transmit action, such as a connecting rod or a rack. The motor 4 can drive the movable partition 3 to rotate. After the damper 55 and the movable partition 3 are linked through the transmission mechanism, a set of devices can be synchronously controlled and linked, with a simple structure and lower cost.

[0050] When the clothes drying device with a switchable air duct of the present utility model is working, the user puts wet clothes into the drying drum 5 and then turns on the machine. The blower 52 makes air circulate in the circulation air duct 51 and the drying drum 5. When the air passes through the heating element 53, it is heated and then enters the drying drum 5. The heated air evaporates and takes away the moisture in the wet clothes, making the air become humid and hot.

[0051] When the motor 4 of the condenser drives the movable partition 3 to cover the first channel opening 17, the movable partition 3 drives the air damper 55 to open the ventilation opening 54 through the transmission mechanism, so that the humid and hot air in the drying drum 5 is discharged from the ventilation opening 54 to the outside of the device through the circulation air duct 51, thus realizing rapid drying of clothes. When the motor 4 drives the movable partition 3 of the condenser to cover the second channel opening 18, the movable partition 3 drives the air damper 55 to close the ventilation opening 54 through the transmission mechanism, so that the humid and hot air in the drying drum 5 circulates inside the drying drum 5 and the circulation air duct 51 of the device. The moisture in the humid and hot air is condensed and precipitated by the condenser and collected as water, so that the humid and hot air becomes dry and then enters the drying drum 5 again after being heated by the heating element 53. Circulating in this way can realize drying of clothes. Such a design can avoid heat loss caused by discharging the heated air to the outside of the device, can quickly raise the temperature of the air in the drying drum 5 and keep the temperature stable, is more conducive to precise software programming control of the drying temperature, enables different types of clothes to obtain better drying effects using different temperature curves, and can avoid deformation and damage of clothes made of high-grade fabrics such as silk due to large temperature fluctuations. At the same time, since the hot air is not discharged to the outside of the device, it can also greatly reduce the power consumption caused by the long-term high-power operation of the heating element 53, thus making the clothes drying process more energy-saving and avoiding the impact on the microenvironment around the device caused by the discharge of humid and hot gas to the outside of the device. Further, since the ventilation opening 54 for discharging to the outside of the device is closed, the noise during the operation of the device can also be reduced.

[0052] In the specific implementation process, the motor 4 can also be connected to the air damper 55. The motor 4 drives the air damper 55 to rotate to open or close the ventilation opening 54. While the air damper 55 rotates, the movable partition 3 is driven to rotate through the transmission mechanism to cover the first channel opening 17 or the second channel opening 18, and the same effect can also be achieved.

[0053] A clothes drying device with a switchable air duct, through the condenser structure with a switchable air duct, provides two working modes: air external circulation and internal circulation. The external circulation mode can quickly dry clothes and is more suitable for usage scenarios such as urgently needing to quickly dry clothes when going out in the morning. The internal circulation mode has a better drying effect and can be controlled programmatically by software to achieve refined drying with different temperature curves for different clothes. Moreover, the drying process is more energy-efficient, environmentally friendly, and quiet. This mode is more suitable for use at night or indoors, as well as drying clothes made of higher-end fabrics, enabling a better drying effect and a more user-friendly experience, thereby significantly enhancing the product's grade positioning and realizing higher market commercial value.

[0054] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
