[0007] a drum arranged in the shell, the drum is provided with an air inlet part and an air outlet part in communication, and the air inlet part is in communication with the first end of the wind channel;

[0008] an airflow driving member arranged on the shell, the airflow driving member is provided with an airflow driving channel, the airflow driving channel is in communication with the air outlet part of the drum and the second end of the wind channel, and an airflow driver is arranged in the airflow driving channel to extract air in the drum to form negative pressure in the drum.

[0009] The clothes drying device provided by the present application has the following advantages: the air inlet part of the drum is in communication with the first end of the wind channel, the air outlet part of the drum is in communication with the second end of the wind channel through the airflow driving channel of the airflow driving member, and the airflow driver is arranged in the airflow driving channel. Under the action of the airflow driver, the air in the drum can be extracted into the wind channel to form negative pressure in the drum, so that the ambient air can enter the drum through the axial ends of the drum and the shell. The ambient air entering the drum can combine with the humid air in the drum to reduce the water vapor saturation temperature, accelerate the water vapor precipitation, and thus reduce the drying time and improve the drying efficiency, thereby improving the user experience.

[0010] In some embodiments, a first air outlet is arranged on the circumferential surface of the drum, and the air outlet part of the drum comprises the first air outlet.

[0011] In some embodiments, the first air outlet is arranged on the circumferential surface of one axial end of the drum, and the first air inlet and a openable clothes door are arranged on the other axial end of the drum, and the air inlet part of the drum comprises the first air inlet, so that the air travel distance in the drum is increased, and the drying efficiency is further improved.

[0012] In some embodiments, the airflow driving member is a volute arranged on the shell, the volute is in communication with the air outlet part of the drum and the second end of the air duct, and the airflow driver comprises a fan arranged in the volute.

[0014] A top cover arranged above the drum, and the volute is arranged in the top cover.

[0015] In some embodiments, the volute is in communication with the air outlet part of the drum through a straight pipe. Since the top cover is arranged above the drum, and the air outlet part of the drum is arranged on the circumferential surface of the drum, the volute can be in communication with the air outlet part of the drum through the straight pipe, so that there is no extra intermediate connecting pipe, and the air resistance is reduced, and the drying efficiency is further improved.

[0016] In some embodiments, the clothes drying device further comprises:

[0017] A heat pump system arranged in the air duct, the heat pump system comprises an evaporator and a condenser arranged in sequence close to the air inlet part of the drum. The wet and hot air in the drum can enter the evaporator of the heat pump system in the air duct through the airflow driver, the wet and hot air from the drum is changed into dry and low-temperature air by the evaporator, the moisture is changed into condensed water and discharged, the low-temperature dry air is heated again by the condenser of the heat pump system, and is introduced into the drum to dry the clothes, to form a closed cycle.

[0018] In some embodiments, a dehumidification part is arranged on the air duct between the heat pump system and the air outlet end of the airflow driving member. Since the drum is under negative pressure, part of the wet and hot air in the drum can be discharged out of the air duct through the dehumidification part, directly into the environment, and the remaining part enters the evaporator of the heat pump system in the air duct to be cooled and dehumidified, then enters the condenser to be heated, to form high-temperature and low-humidity air, and then enters the drum to dry the clothes, to form a semi-open cycle.

[0020] In some embodiments, a temperature detector is arranged in the air duct to detect the temperature of the dehumidifying unit.

[0021] In some embodiments, the dehumidifying unit is arranged between the air outlet end of the air flow driving member and the evaporator, or / and, the dehumidifying unit is arranged between the evaporator and the condenser.

[0022] In some embodiments, the drying device further comprises:

[0023] A heater is arranged in the air duct, and the heater is arranged between the heat pump system and the air inlet of the drum. In this way, the temperature of the dehumidified air after the treatment of the evaporator is increased by the double heat sources formed by the heat pump system and the heater, the temperature of the air introduced into the drum is further increased, the drying time is reduced, and the drying effect is improved.

[0027] determining whether to start the dehumidifying unit according to the real-time detection temperature value.

[0028] In the drying method provided by the application, the dehumidifying unit is started only when it is determined that the temperature of the dehumidifying unit in the air duct is higher than the set temperature. If the temperature of the dehumidifying unit in the air duct is lower than the set temperature, the air in the drum has a relatively small amount of moisture. At this time, the exhaust air is selected, the dehumidifying amount is limited, and in addition, a part of the heat of the air discharged from the dehumidifying unit is lost. In the initial stage of drying, the temperature is low, and at this time, the dehumidifying port is closed, so as to reduce the heat loss and accelerate the increase of the air temperature in the drying cycle.

[0029] Further, the determination of whether to start the dehumidifying unit according to the real-time detection temperature value comprises:

[0030] determining whether the real-time detection temperature value is between 25℃ and 80℃;

DETAILED DESCRIPTION

[0044] ​​​With reference to the drawings and the specific embodiments described below, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

Of course, they are only examples and the purpose is not to limit the present application.

[0047] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0048] The heat pump clothes drying device is a household appliance for further drying clothes after washing machine dehydration. Its working principle is: the airflow driver sends the air heated by the condenser into the drum to dry the clothes. The wet air after the drum further reaches the evaporator of the heat pump system. The evaporator changes the wet hot air from the drum into dry low-temperature air. The moisture becomes condensate water, and the low-temperature dry air is heated again through the condenser of the heat pump system. Thus, a cycle is completed. The heat pump clothes drying device continuously removes moisture and discharges it in the form of condensate water to achieve the purpose of drying clothes through this cycle.

[0049] The traditional clothes drying device has positive pressure in the drum, and the air duct for placing the heat pump system has negative pressure. In this clothes drying device, since the two ends of the drum shaft are sealed between the dynamic seal and the shell, when the drum is under positive pressure, the air in the drum will be discharged between the two ends of the drum shaft and the shell. Although the discharge amount is small, it will still affect the drying time and user experience.

[0050] To solve the above technical problems, the present application provides a clothes drying device and a clothes drying method, which aims to at least partially solve the technical problem of long drying time of the clothes drying device in the prior art, affecting user experience.

The airflow driving channel 1300 is internally provided with the airflow driver 400. The airflow driver 400 is configured to extract air in the drum 200 to form a negative pressure in the drum 200.

[0052] The clothes drying device according to the embodiment of the present application is provided with the air inlet portion of the drum 200 in communication with the first end of the air duct 500, the air outlet portion of the drum 200 in communication with the second end of the air duct 500 through the airflow driving channel 1300 of the airflow driving member 300, and the airflow driver 400 arranged in the airflow driving channel 1300. Under the action of the airflow driver 400, air in the drum 200 can be extracted into the air duct 500 to form a negative pressure in the drum 200. Thus, ambient air can enter the drum 200 through the axial ends of the drum 200 and the shell 100. The ambient air entering the drum 200 can combine with the humid air in the drum 200 to reduce the water vapor saturation temperature and accelerate the water vapor precipitation, thereby reducing the drying time and improving the drying efficiency and user experience.

[0053] Figure 5 Fig. 8 is a schematic diagram of a drum and an airflow driving channel in communication according to an embodiment of the present application. In combination with Figures 2-5In the embodiment of the present application, the circumferential surface of the drum 200 can be provided with a first air outlet 202, and the air outlet part of the drum 200 includes the first air outlet 202. In actual implementation, the drum 200 can be divided into an outer cylinder 203 and an inner cylinder 204, the outer cylinder 203 is fixedly assembled in the shell 100, and the axial two ends of the inner cylinder 204 are rotatably assembled in the shell 100, the first air outlet 202 of the embodiment of the present application is provided on the circumferential surface of the outer cylinder 203, and the inner cylinder 204 can be provided with an air outlet hole 205 at the position of the circumferential surface corresponding to the first air outlet 202 on the outer cylinder 203, the air in the inner cylinder 204 can be discharged to the area between the inner cylinder 204 and the outer cylinder 203 through the air outlet hole 205, and then discharged outside the outer cylinder 203 through the first air outlet 202, that is, discharged to the outside of the drum 200.

[0054] It should be noted that the air outlet hole 205 on the circumferential surface of the inner cylinder 204 of the embodiment of the present application can be provided with one or more, in the case of being provided with a plurality of air outlet holes 205, the plurality of air outlet holes 205 can be arranged in a grid and in a ring. Whether the air outlet hole 205 is provided with one or more, the air outlet hole 205 and the first air outlet 202 are preferably arranged in the same radial direction of the drum 200, so as to reduce the travel of the air and improve the air flow effect, and further improve the drying efficiency.

[0055] In combination Figures 2-5 In the embodiment of the present application, the axial one end of the drum 200 is provided with an openable clothes door 600, the axial one end of the drum 200 is provided with a first air inlet 201, the first air inlet 201 is the air inlet part of the drum 200, and the first air outlet 202 is arranged on the circumferential surface of the drum 200 close to the axial other end of the drum 200. The heated air enters the drum 200 from the first air inlet 201, and then is sequentially discharged to the airflow driving channel 1300 and the air duct 500 from the first air outlet 202 of the drum 200. Since the first air inlet 201 is arranged at the axial one end of the drum 200, and the first air outlet 202 is arranged on the circumferential surface of the drum 200 close to the axial other end of the drum 200, the first air inlet 201 and the first air outlet 202 are arranged close to each other, so as to increase the travel of the heated air inside the drum 200, and further improve the drying efficiency.

[0056] In combination Figure 4The air flow driving member 300 of the embodiment of the present application comprises a volute, the volute has a second air inlet 301, a containing cavity 302, and a second air outlet 303, the second air inlet 301 of the volute is the air inlet end of the air flow driving member 300, the containing cavity 302 is provided with the air flow driver 400, and the second air outlet 303 of the volute is the air outlet end of the air flow driving member 300. In actual implementation, the air flow driver 400 in the volute can extract the air in the drum 200 into the air duct 500, so that the negative pressure is formed in the drum 200, so that the ambient air can enter the drum 200 through the axial two ends of the drum 200 and the shell 100, and the ambient air in the drum 200 can be combined with the humid air in the drum 200, so that the water vapor saturation temperature is reduced, the water vapor is precipitated, the drying time is reduced, the drying efficiency is improved, and the user experience is improved.

[0057] The air flow driver 400 of the embodiment of the present application can comprise a fan arranged in the containing cavity 302 of the volute, and of course, can be other types of air flow directors, which are not limited herein.

[0058] Further, in combination with Figures 2-4 The shell 100 of the embodiment of the present application further comprises a top cover 700, the top cover 700 is arranged above the drum 200, and the volute is arranged in the top cover 700. That is, the volute of the embodiment of the present application is arranged above the drum 200, so that the second air inlet of the volute is communicated with the air outlet part of the drum 200 through the straight pipe 800. Since the top cover 700 is arranged above the drum 200, and the air outlet part of the drum 200 is arranged on the circumferential surface of the drum 200, the second air inlet 301 of the volute can be communicated with the air outlet part of the drum 200 through the straight pipe 800, so that there is no redundant intermediate connecting pipe, and the air resistance is reduced, so as to further improve the drying efficiency.

[0059] It should be noted that the air flow driving member 300 of the embodiment of the present application can also be arranged independently from the shell 100, that is, the air flow driving member 300 is arranged outside the shell 100.

[0060] In other embodiments, the air flow driving member 300 can also be arranged at the axial end of the drum 200, which is consistent with the conventional drying equipment, and the embodiment of the present application does not limit this.

[0061] In combination with Figures 1-4The clothes drying device of the embodiment of the present application further comprises a heat pump system arranged in the air duct 500, which comprises an evaporator 900 and a condenser 1000 arranged in sequence along the air outlet end of the airflow driver 300 to the air inlet part of the drum 200. In actual implementation, the hot and humid air in the drum 200 can enter the evaporator 900 of the heat pump system in the air duct 500 through the airflow driver 400, the evaporator 900 can change the hot and humid air from the drum 200 into dry and low-temperature air, the humidity is changed into condensed water and discharged, the low-temperature dry air is heated again by the condenser 1000 of the heat pump system, and is introduced into the drum 200 to dry the clothes, so as to form a closed cycle. Figure 6 Another system principle schematic diagram of the clothes drying device of the embodiment of the present application is shown in FIG. 6. Figure 6 In the embodiment of the present application, the air duct 500 between the heat pump system and the air outlet end of the airflow driver 300 can be provided with a dehumidification part 501. Since the drum 200 is under negative pressure, part of the hot and humid air in the drum 200 can be discharged out of the air duct 500 through the dehumidification part 501 and directly enter the environment, and the remaining part enters the evaporator 900 of the heat pump system in the air duct 500 to be cooled and dehumidified, then enters the condenser 1000 to be heated, forms high-temperature and low-humidity air, and then enters the drum 200 to dry the clothes, so as to form a semi-open cycle. Since part of the hot and humid air in the drum 200 can be discharged out of the air duct 500 through the dehumidification part 501, the processing load of the evaporator 900 and the condenser 1000 of the heat pump system can be reduced, the cooling and dehumidification effect can be better, the drying time can be further reduced, and the clothes drying efficiency can be improved.

[0062] In the embodiment of the present application, one or more than one hole can be arranged in the air duct 500 between the heat pump system and the air outlet end of the airflow driver 300, and the dehumidification part 501 comprises one or more than one hole, that is, the dehumidification part 501 can comprise only one hole or a plurality of holes.

[0063] Further, the dehumidification part 501 of the embodiment of the present application can be controlled to be opened and closed, so that the dehumidification amount of the dehumidification part 501 can be controlled, the heat loss can be reduced, the air temperature in the drying cycle can be accelerated, and the clothes drying efficiency can be improved.

[0064] In combination with Figure 6 In the embodiment of the present application, a valve 502 that can be opened or closed can be arranged in the dehumidification part 501, and the valve 502 can receive instructions to be automatically opened or closed, so as to realize the opening and closing of the dehumidification part 501.

[0065] Preferably, in combination with Figure 6The dehumidification part 501 of the embodiment of the present application is arranged on the air duct 500 between the air outlet end of the airflow driving member 300 and the evaporator 900. Of course, it can also be arranged on the air duct 500 between the evaporator 900 and the condenser 1000, or arranged on the air duct 500 between the air outlet end of the airflow driving member 300 and the evaporator 900 and the air duct 500 between the evaporator 900 and the condenser 1000.

[0066] In addition, in combination with Figures 1-6 The clothes drying apparatus of the embodiment of the present application can further comprise a heater 1100 arranged on the air duct 500 between the condenser 1000 and the air inlet part of the drum 200. In this way, the air treated by the evaporator 900 and dehumidified can be warmed by the double heat sources formed by the heat pump system and the heater 1100, so as to further increase the temperature of the air introduced into the drum 200, reduce the drying time and improve the drying effect.

[0067] Further, based on the clothes drying apparatus provided with the openable and closable dehumidification part 501, the embodiment of the present application further discloses a clothes drying method. Figure 7 The flowchart of the clothes drying method of the embodiment of the present application is shown in Figure 8 The system schematic diagram of the clothes drying method of the embodiment of the present application is shown in Figure 7 In combination with Figure 7 and Figure 8 The clothes drying method comprises the following steps.

[0068] The processor 1200 obtains a clothes drying instruction and controls the operation of the clothes drying apparatus.

[0069] The processor 1200 receives a real-time detection temperature value of the temperature detector 503, and the real-time detection temperature value is the temperature of the dehumidification part 501 in the air duct 500.

[0070] The processor determines whether to open the dehumidification part 501 according to the real-time detection temperature value.

[0071] In the clothes drying method disclosed by the embodiment of the present application, the dehumidification part 501 is only opened when it is determined that the temperature of the dehumidification part 501 in the air duct 500 is higher than the set temperature. This is because, if the temperature of the dehumidification part 501 in the air duct 500 is lower than the set temperature, the air in the drum 200 has a relatively small amount of moisture. At this time, the exhaust air is selected, and the amount of moisture removed is limited. In addition, a part of the heat of the air removed by the dehumidification part will be lost. At the initial stage of drying, the temperature is relatively low. At this time, the dehumidification port is closed, so as to reduce the loss of the heat and accelerate the increase of the temperature of the drying circulating air.

[0072] In combination with Figure 5 and Figure 7In the embodiment of the present application, the temperature sensor 503 can be arranged at the position of the dehumidification part 501 in the air duct 500, and the temperature sensor 503 is electrically connected to the processor 1200, and can send the real-time temperature of the dehumidification part 501 in the air duct 500 to the processor 1200, so that the processor 1200 sends an instruction of opening or closing the dehumidification part 501, that is, the processor 1200 sends an opening instruction to the valve 502, and the valve 502 can be automatically opened after receiving the opening instruction.

[0073] Further, the determination of whether to open the dehumidification part 501 according to the real-time detection temperature value comprises:

[0074] determining whether the real-time detection temperature value is between 25℃ and 80℃;

[0075] If yes, the dehumidification part 501 is controlled to be opened.

[0076] That is, in the embodiment of the present application, only when it is determined that the temperature of the dehumidification part 501 in the air duct 500 is between 25℃ and 80℃, the dehumidification part 501 can be opened.

[0077] Of course, the dehumidification part 501 can always be in an opened state when the clothes drying device is drying clothes.

[0078] It should be noted that the clothes drying device in the embodiment of the present application can be a washing and drying integrated machine, a clothes dryer or other devices that can dry clothes by hot air, which is not limited specifically herein.

[0079] In summary, the clothes drying device and the clothes drying method provided in the embodiment of the present application can at least solve the technical problem of long drying time of the clothes drying device in the prior art, which affects the user experience, so as to improve the drying efficiency and reduce the drying time, and has good practicability.
