Description

Technical Field

[0001] The utility model relates to a clothes drying device, in particular to a drying module applied in the clothes drying device, the drying module is used for drying clothes placed in a cavity and discharging moisture generated by the drying from the clothes drying device. Background Art

[0002] The clothes drying device can be a dedicated clothes drying machine or a washer-dryer, which circulates hot air to wet clothes in a clothes storage chamber, so that the moisture on the wet clothes is continuously vaporized and carried away by the hot air, thereby drying the clothes.

[0003] The utility model patent with the authorization announcement number CN218521471U discloses a drying module and a washer-dryer, wherein the drying module includes a circulation module, a dehumidification module, a regeneration module and a condensation module. Among them, the circulation module includes a circulation fan to provide power for the wet circulation airflow, the dehumidification module includes a turntable made of a material with good moisture absorption performance, which is used to absorb moisture from the wet circulation airflow in the drum, the regeneration module includes a heater and a regeneration fan, the heater heats the part of the turntable passing through the regeneration module, and continuously desorbs the adsorbed moisture, and the regeneration fan sends the wet and hot regeneration airflow into the condensation module, and the water vapor is cooled and discharged as condensed water.

[0004] It can be seen that the circulation, dehumidification, regeneration and condensation of the drying module are operated simultaneously. During the rotation of the turntable as a moisture absorption and dehumidification component, a part of it is used for moisture absorption, while the other part is heated by the heater for dehydration and regeneration. The regeneration airflow and the wet circulation airflow act on the turntable at the same time. Such a drying module structure and its supporting drying and regeneration program have at least the following technical problems:

[0005] 1. The heater of the regeneration module heats the air in the shell indirectly while heating the turntable, and serves as the hot circulation airflow for drying clothes at the same time. This will cause the temperature in the clothing placement cavity to rise slowly, affecting the drying efficiency. The primary function of the drying module should be to dry clothes, not to dehydrate and regenerate the turntable, which is a problem of putting the cart before the horse.

[0006] 2. The characteristic of the turntable is that it has better moisture absorption at low or normal temperature and is easy to regenerate and dehydrate at high temperature. However, in the drying module, the heater for regeneration and dehydration is always turned on. The turntable that rotates away from the regeneration module does not have time to cool down before it is used for cyclic moisture absorption, resulting in poor moisture absorption effect of the turntable, further affecting the drying efficiency of clothes;

[0007] 3. One blower is configured for each of the circulation module and the regeneration module. The two blowers and the condensation module are crowded together, and the two blowers operate simultaneously, resulting in relatively high energy consumption. At the same time, in order to maintain the smooth rotation of the turntable, the flow directions of the two airflows, namely the regeneration airflow and the wet circulation airflow, are set to be opposite. Separation parts and seals need to be additionally arranged inside the housing to prevent the two airflows from mixing with each other, further complicating the structure. Summary of the Invention

Detailed implementation manners

[0058] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0059] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. The terms "first" and "second" are only for descriptive convenience and have no other directional meaning, and should not be construed as limiting the present invention.

[0060] AsFigure 1 and Figure 2 As shown in Figure 2 , the clothes drying device 200 provided in this embodiment includes a clothes placement cavity 201 and a drying module 100. Among them, the drying module 100 is arranged on the top of the clothes placement cavity 201 to facilitate air circulation and the drainage of condensed water by its own weight. The clothes drying device 200 can be a single clothes dryer or a washing and drying integrated machine, etc.

[0061] Specifically looking at the drying module 100, as Figure 3 shown, the drying module 100 includes a runner housing 10, a dehumidifying runner 20, a blower 30 arranged beside the runner housing 10, a drying heating module 40 and a regeneration heating module 50. A water vapor exchange cavity t is formed inside the runner housing 10, and the dehumidifying runner 20 is arranged in the water vapor exchange cavity t and can rotate circumferentially.

[0062] The runner housing 10 is provided with an air outlet 11, and the blower 30 is provided with an air inlet 31. The air outlet 11 and the air inlet 31 are used to communicate with the clothes placement cavity 201. As Figure 7 shown, when the blower 30 is started, air flow is sent into the water vapor exchange cavity t, and after passing through the dehumidifying runner 20, it is sent out from the air outlet 11 for entering the clothes placement cavity 201, and then returns to the blower 30 from the air inlet 31 to form a circulating air flow path p.

[0063] The drying heating module 40 is arranged at a downstream position of the dehumidifying runner 20 within the circulating air flow path p. The regeneration heating module 50 is arranged close to the disk surface of the dehumidifying runner 20.

[0064] In this embodiment, the drying heating module 40 is arranged at the position of the air outlet 11. Since when the blower 30 is started, the air flow is sent out from the air outlet 11 after passing through the dehumidifying runner 20, it can be known that the air outlet 11 is located at a downstream position of the dehumidifying runner 20 within the circulating air flow path p. In other embodiments, the drying heating module 40 can also be arranged at other positions to meet the condition of being at a downstream position of the dehumidifying runner 20 within the circulating air flow path p. For example, it can be arranged at a position within the runner housing 10 between the dehumidifying runner 20 and the air outlet 11, or within the air outlet pipe 14, etc. This embodiment selects to be arranged at the position of the air outlet 11, which is convenient for the assembly, disassembly and replacement of the heating module 40.

[0065] As Figure 7As shown in the figure, in the drying mode, the blower 30, the dehumidification rotor 20, and the drying heating module 40 are started, and the regeneration heating module 50 is turned off. The air flow is heated by the drying heating module 40 at the downstream position of the dehumidification rotor 20, that is, at the air outlet 11, to form a drying warm air flow, which is sent into the clothing placement cavity 201 to dry the wet clothes inside. At this time, after the drying warm air flow absorbs the moisture in the wet clothes, it becomes a water-vapor-carrying air flow and returns to the water-vapor exchange cavity t along the circulating air flow path p. The dehumidification rotor 20 is used to adsorb the moisture in the air flow, so that the air flow after the water-vapor exchange with it re-enters the circulating air flow path p.

[0066] As Figure 8 shown in the figure, in the regeneration mode, the blower 30, the dehumidification rotor 20, and the regeneration heating module 50 are started, and the drying heating module 40 is turned off. The regeneration heating module 50 is used to cooperate with the air flow generated by the blower 30 to heat and dehydrate and regenerate the dehumidification rotor 20. Specifically, the regeneration heating module 50 heats the circumferentially rotating dehumidification rotor 20, and the dehumidification rotor 20 starts to dehydrate when heated. The vaporized moisture is taken away by the air flow in real time, enters the circulating air flow path p, and is then discharged.

[0067] It can be seen that the drying module 100 provided by the present utility model sets the drying mode and the regeneration mode as two relatively independent programs, and separately sets and independently operates the drying heating module 40 for forming the drying warm air flow and the regeneration heating module 50 for heating and dehydrating and regenerating the dehumidification rotor 20, thereby achieving the following beneficial effects:

[0068] First, only one blower 30 is used to form a circulating air flow path p with a constant air flow direction, and the drying of clothes and the regeneration of the dehumidification rotor 20 can be completed. Compared with the prior art, the number of blowers is streamlined, the arrangement of the mechanism components is more relaxed, the cost is saved, and there is no problem of the mutual penetration of two relatively opposite air flows. Therefore, there is no need to set partition members or sealing members inside the rotor housing 10, and the contact between the dehumidification rotor 20 and the air flow is more sufficient, and the efficiency of moisture absorption and dehydration is improved.

[0069] Second, the drying mode and the regeneration mode operate relatively independently, and each starts its own exclusive heating module, that is, the drying heating module 40 is turned on in the drying mode, and the regeneration heating module 50 is turned off. The regeneration heating module 50 is turned on in the regeneration mode, and the drying heating module 40 is turned off. The heating efficiency in both modes is improved. Especially in the drying mode, the temperature rising speed in the clothing placement cavity 201 is fast, and the drying efficiency is correspondingly improved.

[0070] Thirdly, the drying and heating module 40 is arranged downstream of the dehumidifying rotor 20. Thus, in the drying mode, the dehumidifying rotor 20 can maintain normal and low temperatures, overcoming the defect in the prior art that the dehumidifying rotor still has the residual heat of the heater of the regeneration module in the drying mode, resulting in a reduction in the moisture absorption efficiency. While improving the moisture absorption efficiency of the dehumidifying rotor 20, the drying efficiency is further enhanced.

[0071] As Figure 3 shown, the rotor housing 10 includes an upper housing disk 12 and a lower housing disk 13. The upper housing disk 12 and the lower housing disk 13 are joined together to form a water vapor exchange cavity t inside the rotor housing 10. The central position of the rotating shaft of the dehumidifying rotor 20 rotating circumferentially is pivotally connected between the upper housing disk 12 and the lower housing disk 13. In this embodiment, the fan 30 is a worm fan, and the air outlet 32 of the worm fan is connected to the lower housing disk 13. The circumferential side wall of the upper housing disk 12 extends laterally to form an air outlet 11. Thus, when the fan is started, the air flow passes through the dehumidifying rotor 20 from the lower housing disk 13, enters the upper housing disk 12, and is then sent out from the air outlet 11.

[0072] As Figure 3 shown, a rotor driving assembly 60 is further provided beside the rotor housing 10. The rotor driving assembly 60 includes a driving motor 61 and a driving gear 62. A driven tooth (not shown in the figure) is provided on the circumferential side of the dehumidifying rotor 20, and the driving gear 62 meshes with the driven tooth of the dehumidifying rotor 20. When the driving motor 61 is started, it can drive the driving gear 62 to rotate, so as to drive the dehumidifying rotor 20 to rotate circumferentially inside the rotor housing 10.

[0073] In other embodiments, the dehumidifying rotor 20 can also adopt other driving methods. For example, the rotor driving assembly 60 adopts a driving motor and a transmission belt. The transmission belt is used as a transmission member and is sleeved on the output shaft of the driving motor and the dehumidifying rotor. Thus, the driving motor drives the transmission belt to drive the dehumidifying rotor 20 to rotate circumferentially inside the rotor housing 10. The gear transmission method is not prone to problems such as slipping that reduce the transmission efficiency.

[0074] Furthermore, the drying module 100 further includes a condensation assembly 70. The condensation assembly 70 is arranged in the circulating air flow path p and at the upstream position of the fan 30. In the regeneration mode, the fan 30, the dehumidifying rotor 20, the regeneration heating module 50, and the condensation assembly 70 are started, and the drying and heating module 40 is closed. The condensation assembly 70 is used to condense the moisture in the air flow so as to discharge the clothes drying device 200.

[0075] Of course, in other embodiments, the condensation component 70 may not be specifically provided, and natural cooling may be utilized during the circulation of the air flow within the circulation air flow path p, such that the moisture therein condenses and is discharged. The arrangement of the condensation component 70 upstream of the blower 30 has at least two advantages: First, compared with natural cooling, the condensation component 70 can improve the efficiency of moisture condensation; second, it can condense moisture as much as possible at the upstream position of the blower 30, so that the humidity of the air flow entering the blower 30 and returning to the dehumidifying rotor 20 again is reduced as much as possible, ensuring that the efficiency of regeneration and dehydration is not affected.

[0076] As Figure 3 and Figure 4 shown, the air outlet 11 is connected to an air outlet pipe 14 for communicating with the clothing placement cavity 201, and the air inlet 31 is connected to an air inlet pipe 33 for communicating with the clothing placement cavity 201. Among them, as Figures 5 to 7 shown, a filter screen 34 is disposed obliquely downward from top to bottom within the air inlet pipe 33 for filtering lint in the air flow. The projection of the filter screen 34 on the cross-section of the air inlet pipe 33 coincides with the cross-section of the air inlet pipe 33, that is, the edge of the filter screen 34 fits against the inner side wall of the air inlet pipe 33, so as to prevent lint from escaping through the connection seam therebetween and entering the blower 30 or the rotor housing 10, affecting the normal operation of the blower 30 and the dehumidifying rotor 20.

[0077] The air inlet pipe 33 is further provided with a filter screen cleaning component, and the filter screen cleaning component includes a solenoid valve 71, a spray pipe 72, and a flushing nozzle 73. The solenoid valve 71 is used to control the spray water flow w to be ejected from the flushing nozzle 73 via the spray pipe 72, and the flushing nozzle 73 is aligned with the high position of the filter screen 34, so that the spray water flow w can flow through the filter screen 34 along the trend, thereby cleaning the entire filter screen 34.

[0078] It should be noted that the solenoid valve 71 in this embodiment is used as a waterway switch. The waterway switch is connected to a pressure water source (such as tap water) or a water storage box, and by controlling the opening and closing of the pressure water source or the water storage box, the spray water flow w is controlled to be ejected from the flushing nozzle 73 via the spray pipe 72. In other embodiments, the waterway switch can also use a water pump or the like to replace the solenoid valve 71 in this embodiment.

[0079] In this embodiment, the filter cleaning assembly also serves as the condensation assembly 70, which is used to condense the moisture in the airflow passing through the intake duct 33 so that the condensed water is discharged from the clothing drying device 200 via the intake duct 33. In the regeneration mode, after the airflow takes away the moisture and heat dehydrated by the regeneration heating module 50 from the dehumidification rotor 20 in the water vapor exchange chamber t, it becomes a humid and hot airflow, and comes to the intake duct 33 through the circulating airflow path p. At this time, since the condensation assembly 70 is in an open state, the spray water flow w ejected by the flushing nozzle 73 covers the entire filter screen 34, and the humid and hot airflow is instantaneously cooled when passing through quickly. The water vapor therein is condensed and discharged from the intake duct 33 downward together with the spray water flow w from the clothing drying device 200, realizing the two functions of cleaning the filter screen 34 and condensing the moisture in the airflow at the same time.

[0080] It should be noted that like reference numerals represent like items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0081] The drying module and the clothing drying device provided by the present utility model have been introduced above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
