Description

Technical Field

[0001] This application relates to the field of clothing care technology, and more particularly to a clothes drying device. Background Technology

[0002] Taking a heat pump dryer as an example, the evaporator located on the circulation path cools and dehumidifies the high-temperature and humid airflow. Then, the condenser heats the low-temperature and dry airflow flowing through the evaporator. The heated airflow flows into the drying drum to dry the clothes. The airflow flowing through the drum becomes a high-temperature and humid airflow and flows through the evaporator again. This cycle is repeated to achieve continuous drying of clothes.

[0003] In related technologies, filters are installed in the upstream air duct of the circulating flow path to filter the airflow, but a large amount of lint will still pass through the filters and enter the evaporator and condenser, affecting the working efficiency of the evaporator and condenser; at the same time, lint adhering to the filters will also affect the air volume and increase the air resistance.

[0035] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0036] In the description of the embodiments of the present application, it should be noted that the terms "transverse", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "height direction" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] The embodiments of the present application provide a clothes drying device, please refer to Figure 1 and Figure 2 , comprising a cabinet assembly, a drying drum 1, a filter box 5.

[0038] The space inside the drying drum 1 is a clothes treatment cavity 1a.

[0039] The drying drum 1 is arranged in the cabinet assembly. It should be noted that the clothes drying device is provided with a motor which directly or indirectly drives the drying drum 1 to rotate in the cabinet assembly.

[0040] The cabinet assembly comprises a front support 2, please refer to 1, Figure 2 and Figure 3 , the front support 2 is provided with a clothes feeding port 2a and a mounting slot 20 (refer to Figure 5 ). The front support 2 is located at the front side of the drying drum 1, the clothes feeding port 2a is in communication with the clothes treatment cavity 1a, and the user takes and puts clothes from the clothes feeding port 2a.

[0041] It should be noted that the cabinet assembly further comprises a front sealing door arranged at the front side of the front support 2. The front sealing door serves as an appearance part of the clothes drying device.

[0042] It should be noted that the clothes drying device is provided with a drying air duct and a condensation and dehumidification air duct, the drying air duct is provided with a heater and a fan, and the condensation and dehumidification air duct is provided with a condensation and dehumidification device.

[0043] Specifically, the dry hot air flow heated by the heater enters the clothes treatment cavity 1a under the action of the fan. In the clothes treatment cavity 1a, the dry hot air flow flows through the surface of the wet clothes and exchanges heat and moisture with the wet clothes, absorbs the water in the clothes, and becomes a wet hot air flow. The wet hot air flow enters the condensation and dehumidification air duct, and in the process of flowing through the condensation and dehumidification device, the water vapor in the wet hot air flow is condensed into water droplets due to the cooling, and the wet hot air flow is condensed and dehumidified to form a low-temperature dry air flow.

[0044] It should be noted that in some embodiments, the low-temperature dry airflow is directly discharged to the indoor or outdoor, that is, in this embodiment, the drying air duct and the condensation and dehumidification air duct are independent of each other, the drying air duct introduces the ambient air at room temperature into the surrounding environment, and the condensation and dehumidification air duct discharges the dehumidified airflow to the indoor or outdoor. In other embodiments, the low-temperature dry airflow enters the drying air duct, that is, in this embodiment, the condensation and dehumidification air duct and the drying air duct are communicated, the condensation and dehumidification air duct, the drying air duct, and the clothes processing cavity 1a form an airflow circulation loop, and the airflow circulates in the airflow circulation loop.

[0045] The filter box 5 is arranged in the mounting groove 20, and the front support 2 provides a mounting space for the filter box 5, and the filter box 5 and the front support 2 always remain relatively stationary. It should be noted that the filter box 5 is located upstream of the condensation and dehumidification air duct.

[0046] In the embodiments of the present application, please refer to Figure 1 , Figure 2 and Figure 3 , the clothes drying apparatus includes a cyclone separation mechanism 4 arranged upstream of the filter box 5 along the airflow flow direction. The cyclone separation mechanism 4 is used for cyclone separation of the airflow from the drying drum 1, and the airflow after cyclone separation by the cyclone separation mechanism 4 flows through the filter box 5. That is, the wet and hot airflow flowing through the clothes processing cavity 1a first flows through the cyclone separation mechanism 4, and then flows through the filter box 5 after being separated by the cyclone separation mechanism 4, and then enters the condensation and dehumidification air duct.

[0047] The cyclone separation mechanism 4 is a mechanism for separating gas-solid systems, and the working principle is that the rotational motion generated by the airflow introduced into the inside makes the solid impurities such as lint and fibers with large inertia centrifugal force fly to the wall surface radially outward to be separated from the gas.

[0048] The clothes drying apparatus of the embodiments of the present application first performs gas-solid separation on the wet and hot airflow flowing through the drying drum 1 through the cyclone separation mechanism 4, and the impurities with large size are quickly and effectively separated from the airflow. It should be noted that the impurities separated by the cyclone separation mechanism 4 are collected uniformly. The separated gas continues to flow to the filter box 5 for further filtration, and the filtered gas enters the condensation and dehumidification air duct. That is, the airflow at least undergoes two-stage lint removal treatment, which can not only improve the efficiency but also effectively reduce the impurity content in the airflow discharged from the filter box 5 and reduce the pollution to the condensation and dehumidification device or indoor air. In addition, the cyclone separation mechanism 4 has simple structure, high separation efficiency, does not need to use filter screen, and thus does not have the phenomenon of clogging the filter screen, has no vulnerable parts, basically does not need regular maintenance, and has high reliability.

[0049] In addition, since the cyclone separation mechanism 4 reduces the filtering burden of the filter box 5, the service life of the filter screen of the filter box 5 can be improved, and the filter screen clogging of the filter box 5 can be obviously improved, the frequency of cleaning the filter box 5 by the user is reduced, and the user experience is improved.

[0050] It should be noted that the type of the condensation dehumidifier is not limited, for example, in some embodiments, the condensation dehumidifier is a water cooler, which cools and dehumidifies the hot and humid air flow by condensing water. In this embodiment, the heater can be a resistance wire or the like. In other embodiments, the condensation dehumidifier is an evaporator in a heat pump system. In this embodiment, the clothes drying apparatus includes a heat pump system, and the heat pump system includes a compressor, an evaporator, and a condenser. The compressor, the evaporator, and the condenser are arranged in series on a refrigerant circuit. The condenser serves as the heater described above. The air flow sequentially flows through the evaporator and the condenser.

[0051] In the embodiments of the present application, the evaporator of the condensation dehumidifier is taken as an example for description.

[0052] Exemplarily, the clothes treatment apparatus includes a base 3. The cabinet assembly is covered on the base 3. The top side of the base 3 is provided with a mounting cavity. The evaporator and the condenser are arranged in the mounting cavity. The mounting cavity is located on the air flow circulation loop. That is, the heat pump system is arranged on the base 3 below the drying drum 1.

[0053] It should be noted that, since the evaporator and the condenser are arranged on the base, if the heat exchange efficiency of the evaporator and / or the condenser is seriously reduced, the user or the after-sales personnel cannot disassemble the clothes drying apparatus on site, and it is necessary to transport it to a special repair workshop for repair. This will seriously increase the user's use cost and affect the user experience. The evaporator and the condenser generally adopt a finned structure. The air flow flows through the fin gap. If the air flow carries a large amount of lint and other impurities, the impurities are easily attached to the fins and block the gap. Therefore, it is particularly important to remove the impurities from the air flow.

[0054] In the related art, the filtering level of the filter screen is improved by arranging multiple layers of filter screens on the filter box or reducing the mesh size of the filter screen. However, the air resistance is obviously increased, and the filter screen is quickly blocked by impurities, and the filtering efficiency is low.

[0055] In the embodiments of the present application, the two-stage impurity removal treatment of the cyclone separation mechanism 4 and the filter box 5 on the impurities in the air flow can effectively and obviously improve the phenomenon that the impurities block the evaporator and the condenser, improve the heat exchange efficiency of the evaporator and the condenser, and balance the filtering efficiency.

[0056] Exemplarily, please refer to Figure 5 The mounting groove 20 is located at the bottom of the circumferential side wall of the clothes feeding port 2a, which facilitates the user to take and place the filter box 5 from the mounting groove 20.

[0057] The specific position of the cyclone separating mechanism 4 is not limited. Exemplarily, the cyclone separating mechanism 4 is arranged at the front side of the front support 2. It should be noted that the cyclone separating mechanism 4 is located between the front sealing door and the front support 2. In this embodiment, the space between the front side of the front support 2 and the rear side of the front sealing door can be fully utilized, and the space is sufficient to accommodate the cyclone separating mechanism 4, and the cyclone separating mechanism 4 basically does not affect the assembly relationship between the front support 2 and the base 3, nor does it affect the assembly relationship between the front support 2 and the drying drum 1.

[0058] Exemplarily, referring to Figure 3 In the planar projection perpendicular to the rotation axis of the drying drum 1, the cyclone separating mechanism 4 and the filter box 5 surround the clothes feeding opening 2a.

[0059] In this embodiment, the cyclone separating mechanism 4 is arranged around the clothes feeding opening 2a, so that the area around the clothes feeding opening 2a can be fully utilized, and the structure is compact and reasonable.

[0060] Exemplarily, referring to Figure 3 In the planar projection perpendicular to the rotation axis of the drying drum 1, the projection of the cyclone separating mechanism 4 is located within the projection of the front support 2. That is, the cyclone separating mechanism 4 does not exceed the contour range of the front support 2, and the cyclone separating mechanism 4 also does not extend into the clothes feeding opening 2a, avoiding affecting the user to take and place clothes. In this embodiment, the cyclone separating mechanism 4 does not affect the contour size of the front support 2, and basically does not affect the assembly relationship of the front support 2 with other structures.

[0061] It should be noted that the hot and humid airflow in the drying drum 1 can be introduced into the cyclone separating mechanism 4 at any appropriate position.

[0062] Exemplarily, referring to Figure 1 and Figure 2 The circumferential side wall of the clothes feeding opening 2a is provided with a flow port 2c in communication with the cyclone separating mechanism 4, and the hot and humid airflow of the drying drum 1 enters the cyclone separating mechanism 4 through the flow port 2c. In this way, the cyclone separating mechanism 4 can be arranged around the clothes feeding opening 2a, and the cyclone separating mechanism 4 does not interfere with the clothes feeding opening 2a.

[0063] It should be noted that the impurities can be collected at any appropriate position.

[0064] Exemplarily, referring to Figure 5 and Figure 8 The filter box 5 includes a filter cavity 5a and an impurity collection cavity 5b which are isolated from each other. Among them, the isolation means that the filter cavity 5a and the impurity collection cavity 5b are not communicated with each other, and there is no airflow exchange between them.

[0065] Referring to Figure 5The airflow separated by the cyclone separation mechanism 4 flows through the filter cavity 5a, and the impurities separated by the cyclone separation mechanism 4 are collected in the impurity collection cavity 5b. In this embodiment, the same filter box 5 has both the effect of filtering the airflow and the effect of collecting impurities. After the user takes out the filter box 5, the user can clean the filter screen of the filter cavity 5a and clean the impurities in the impurity collection cavity 5b, and the dryer does not need to be additionally provided with another component to collect impurities, so that the dryer has a compact structure.

[0066] It can be understood that, referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 , the filter box 5 is provided with an impurity inlet 5d, an air inlet 5c and an air outlet 5f. The impurity inlet 5d is in communication with the impurity collection cavity 5b, and the impurities enter the impurity collection cavity 5b through the impurity inlet 5d. The filter cavity 5a is in communication with the air inlet 5c and the air outlet 5f, and the airflow enters the filter cavity 5a through the air inlet 5c and is discharged from the filter box 5 through the air outlet 5f.

[0067] It should be noted that the filter screen is covered at the air outlet 5f.

[0068] Exemplarily, the side wall of the impurity collection cavity 5b is a non-air-permeable structure. That is to say, except for the impurity inlet 5d, the side wall of the impurity collection cavity 5b will not have airflow flowing therethrough, so that the airflow in the cyclone separation mechanism 4 is prevented from being discharged from the impurity collection cavity 5b.

[0069] Exemplarily, the filter box 5 only takes in air through the air inlet 5c. That is to say, the hot and humid airflow in the drying drum 1 cannot directly enter the filter box 5, but needs to pass through the cyclone separation mechanism 4 first before entering the filter box 5, so as to ensure the separation effect of the cyclone separation mechanism 4.

[0070] The setting position of the impurity inlet 5d on the filter box 5 is not limited, as long as the impurities can enter the impurity collection cavity 5b conveniently.

[0071] The setting position of the air inlet 5c on the filter box 5 is not limited, as long as the airflow from the cyclone separation mechanism 4 can enter the filter cavity 5a conveniently.

[0072] Exemplarily, referring to Figure 5 and Figure 8The impurity inlet 5d and the air inlet 5c are arranged on opposite sides of the filter box 5. For example, if the impurity inlet 5d is arranged on the left side of the filter box 5, the air inlet 5c is arranged on the right side of the filter box 5; if the impurity inlet 5d is arranged on the right side of the filter box 5, the air inlet 5c is arranged on the left side of the filter box 5. The arrangement of the impurity inlet 5d and the air inlet 5c in this embodiment facilitates the arrangement of the pipe of the cyclone separation mechanism 4, and facilitates the introduction of impurities from one lateral side of the filter box 5 into the impurity collection cavity 5b and the introduction of air flow from the other lateral side of the filter box 5 into the filter cavity 5a.

[0073] For example, the filter cavity 5a and the impurity collection cavity 5b are arranged in the left-right direction, for example, the left space in the filter box 5 is the impurity collection cavity 5b, and the left space in the filter box 5 is the filter cavity 5a. The arrangement of this embodiment facilitates the structural arrangement of the filter box 5, and also makes the left and right sides of the filter box 5 have sufficient area to arrange the impurity inlet 5d and the air inlet 5c. Specifically, the front support 2 has a relatively small size in the front-rear direction, and therefore the filter box 5 also has a relatively small size in the front-rear direction, but the filter box 5 can have a relatively large size in the left-right direction, so that the space in the filter box 5 can be arranged in the left-right direction.

[0074] The specific structure of the filter box 5 is not limited.

[0075] For example, referring to Figure 6 , Figure 7 and Figure 8 , the filter box 5 comprises a shell 51, a bottom plate 52, and a partition plate 53. The bottom side of the shell 51 is open, and the bottom plate 52 is arranged at the open part of the shell 51 to open or close the open part of the shell 51.

[0076] The bottom plate 52 and the shell 51 jointly define a hollow cavity, the partition plate 53 is arranged in the hollow cavity and connected with the shell 51, and the hollow cavity is divided into the impurity collection cavity 5b and the filter cavity 5a arranged in the left-right direction. It should be noted that the partition plate 53 is also detachable from the bottom plate 52, so that the bottom plate 52 can be opened.

[0077] In this embodiment of the filter box 5, after the filter box 5 is taken out of the mounting groove 20, the bottom plate 52 is opened, and the impurities in the impurity collection cavity 5b can be poured out. In addition, it is also convenient to clean the filter screen arranged on the bottom plate 52 or the shell 51.

[0078] The specific connection mode of the bottom plate 52 and the shell 51 is not limited, as long as it is convenient for users to disassemble.

[0079] For example, the bottom plate 52 is rotationally connected with the shell 51. In this embodiment, when the bottom plate 52 is opened, the bottom plate 52 still maintains a connection relationship with the shell 51 and does not separate from the shell 51.

[0080] For another example, please refer to Figure 6 and Figure 8 , the bottom plate 52 is provided with an elastic hook 521, and the shell 51 is provided with a clamping groove 51a, the elastic hook 521 is hooked into the clamping groove 51a. In this embodiment, when the bottom plate 52 needs to be opened, the elastic hook 521 is forced to exit the clamping groove 51a, and when the bottom plate 52 is opened, the bottom plate 52 is completely separated from the shell 51.

[0081] The position of the air outlet 5f is not limited. For example, the air outlet 5f is arranged on the front side wall of the shell 51, or arranged on the rear side wall of the shell 51.

[0082] For another example, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, the second air outlet 5f is arranged on the bottom plate 52, that is, the filter screen is also arranged on the bottom plate 52. When the bottom plate 52 is removed, it is convenient to clean the filter screen on the bottom plate 52.

[0083] Exemplarily, please refer to Figure 6 and Figure 8 , the filter box 5 includes a handle 54, and the handle 54 is arranged on the top side of the shell 51, which is convenient for the user to hold.

[0084] The specific structure of the handle 54 is not limited, as long as it is convenient for the user to hold.

[0085] Exemplarily, the above-mentioned shell 51, handle 54 and partition plate 53 can be an integral structure, or can be a split structure and assembled together.

[0086] It should be noted that along the radial direction of the clothes throwing opening 2a, the top of the shell 51 can protrude from the circumferential inner surface of the clothes throwing opening 2a, or can not protrude from the circumferential inner surface of the clothes throwing opening 2a.

[0087] The specific structure of the cyclone separation mechanism 4 is not limited.

[0088] Exemplarily, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the cyclone separation mechanism 4 includes a cyclone separator 41, an air outlet pipeline 42 and a impurity pipeline 43.

[0089] The cyclone separation mechanism 4 realizes gas-solid separation through the cyclone separator 41. The airflow from the clothes drying drum 1 enters the cyclone separator 41 through the air inlet, and the lint and other impurities are separated in the cyclone separator 41. The separated airflow enters the air outlet pipeline 42, and the separated impurities enter the impurity pipeline 43 from the bottom of the cyclone separator 41.

[0090] The impurity pipeline 43 is used to guide the impurities separated by the cyclone separator 41 to the impurity collection cavity 5b of the filter box 5, and the air outlet pipeline 42 is used to guide the air flow separated by the cyclone separator 41 to the filtering cavity 5a of the filter box 5. In this embodiment, both the air flow and the impurities separated by the cyclone separation mechanism 4 are introduced into the filter box 5, so that the structure is compact and it is also convenient for the user to clean the impurities.

[0091] It should be noted that the arrangement of the impurity pipeline 43 needs to be such that the impurities can move in the impurity pipeline 43 under the action of gravity and finally move into the impurity collection cavity 5b.

[0092] The cyclone separator 41 can adopt any cyclone separation technology in the prior art as long as it can separate the impurities from the air flow by the rotational centrifugal force of the air flow.

[0093] The arrangement of the air outlet pipeline 42 described above can be piped according to the position of the air outlet of the cyclone separator 41 and the air inlet 5c of the filtering cavity 5a.

[0094] Some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the impurity pipeline 43 and the cyclone separator 41 are arranged on the same side of the transverse direction of the clothes throwing opening 2a, for example, both are arranged on the left side of the clothes throwing opening 2a; the air outlet pipeline 42 passes above the clothes throwing opening 2a from the top of the cyclone separator 41 and is arranged to the other side of the transverse direction of the clothes throwing opening 2a, so that the bending amplitude of the air outlet pipeline 42 is relatively gentle, and the flow resistance of the air flow in the air outlet pipeline 42 is reduced.

[0095] It can be understood that, under the condition of meeting the piping requirements, the position of the cyclone separator 41 is as high as possible to reduce the length of the air outlet pipeline 42 and reduce the wind resistance.

[0096] Exemplarily, the position of the air inlet of the cyclone separator 41 is higher than the center of the clothes throwing opening 2a, on the one hand, the cyclone separator 41 is as close as possible to the upper left corner or the upper right corner of the front support 2, and the upper left corner or the upper right corner has a larger installation space.

[0097] Exemplarily, please refer to Figure 5The left and right opposite sidewalls 201 of the mounting groove 20 are provided with through holes 201a. One end of the impurity pipeline 43 is covered around one of the through holes 201a, the left and right opposite sidewalls of the shell 51 are in contact with the left and right sidewalls 201 of the mounting groove 20, and the impurity inlet 5d is substantially aligned with one of the through holes 201a. One end of the air outlet pipeline 42 is covered around the other through hole 201a, and the air inlet 5c of the filter cavity 5a is substantially aligned with the other through hole 201a. In this way, the impurity pipeline 43 and the air outlet pipeline 42 do not interfere with the filter box 5.
