Description

Technical Field

[0001] The embodiments of the present invention relate to the field of household appliances, and in particular to a drying system for a drying cabinet. The present invention also relates to a corresponding drying cabinet. Background Art

[0002] In recent years, with the advancement of technology and the improvement of living standards, more and more families choose to use drying cabinets to store clothes while removing moisture from clothes through a drying system, thereby keeping clothes dry and clean and preventing clothes from getting moldy, discolored or producing odors.

[0003] In existing drying cabinets, the drying system is usually integrated and arranged at the bottom of the drying cabinet. The hot air generated by the drying system is blown into the clothing storage chamber of the drying cabinet from below through a single air outlet, and then discharged from a single return air outlet below the clothing storage chamber. This makes the flow path of the hot air in the clothing storage chamber shorter, and part of the hot air is discharged from the return air outlet before it has time to exchange heat, resulting in low heat exchange efficiency and energy waste. Summary of the invention

[0004] Therefore, one purpose of an embodiment of the present invention is to propose an improved drying system for a drying cabinet, which can increase the flow path of hot air in the clothing storage chamber and significantly improve the heat exchange efficiency of the air, thereby effectively improving the working performance of the drying system and saving energy.

Here, since the air density of the hot air is lower than the air density of the cold air, the hot air generated by the heating module first stays above the clothing storage chamber after entering the clothing storage chamber, and then the hot air decreases in temperature with sufficient heat exchange with the clothing and gradually sinks to the bottom of the clothing storage chamber, and further flows into the condensing module, thereby enabling the air flow path to extend through the entire clothing storage chamber and achieve sufficient heat exchange between the hot air and the clothing, thereby significantly improving the working efficiency of the drying system and avoiding energy waste as much as possible.

[0034] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention. Here, for the sake of brevity, elements with the same reference numerals are marked only once in the drawings when necessary.

[0035] It should be understood that, in this document, the expressions "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor should they be understood as implicitly indicating the number of technical features indicated. Features defined as "first" or "second" may explicitly or implicitly indicate that at least one of the features is included.

[0036] In the description of the present embodiment, the words and phrases indicating the orientation or positional relationship, such as "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., are used to illustrate the positional relationship of the constituent elements with reference to the accompanying drawings. This is only for the convenience of describing the present specification and simplifying the description, and does not indicate or imply that the device or element referred to has a specific orientation, is constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the direction in which each constituent element is described. Therefore, it is not limited to the words and phrases described in the specification, and can be appropriately replaced according to the circumstances. Here, according to the definition of the XYZ rectangular coordinate system in the accompanying drawings: the X direction corresponds to the width direction of the dry cabinet 100, the Y direction corresponds to the depth direction of the dry cabinet 100, and the Z direction corresponds to the height direction of the dry cabinet 100.

[0037] Figure 1 A front view of a drying cabinet 100 according to an exemplary embodiment of the present invention is shown. Figure 2a and Figure 2b The figures respectively show three-dimensional views of a drying cabinet 100 according to an exemplary embodiment of the present invention. Figure 3a and Figure 3b The figures respectively show three-dimensional views of a drying system 120 for a drying cabinet 100 according to an exemplary embodiment of the present invention. Figure 4 An exploded view of the condensation module 20 of the drying system 120 according to an exemplary embodiment of the present invention is shown.

[0038] like Figure 1 and Figure 2a As shown, the drying cabinet 100 includes a shell 110, which defines an internal space of the drying cabinet 100 through its peripheral wall. The internal space has a clothing storage chamber 111 for receiving clothing. The clothing storage chamber can be closed by a door body not shown here to form a closed chamber and prevent external dust from contaminating the clothing in the clothing storage chamber 111.

[0039] like Figure 1 and Figure 3aAs shown, the drying cabinet 100 includes a drying system 120, which includes at least a heating module 10, a condensing module 20 and at least one return air duct 30 arranged between the heating module 10 and the condensing module 20, wherein the heating module 10 is arranged above the clothing storage chamber 111 of the drying cabinet 100 and is configured to heat air and supply the heated air to the clothing storage chamber 111, the condensing module 20 is arranged below the clothing storage chamber 111 of the drying cabinet 100 and is configured to receive and cool the air from the clothing storage chamber 111, and the return air duct 30 is capable of transporting the air cooled by the condensing module 20 back to the heating module 10.

[0040] Here, since the air density of hot air is lower than that of cold air, the hot air generated by the heating module 10 first stays above the clothing storage chamber 111 and exchanges heat with the clothing after entering the clothing storage chamber 111, and then the hot air drops in temperature and absorbs moisture as it fully exchanges heat with the clothing, thereby gradually sinking to the bottom of the clothing storage chamber 111 and further flowing into the condensing module 20. In this process, the flow path of the hot air extends from the top to the bottom of the clothing storage chamber 111, which can achieve full heat exchange between the hot air and the clothing in the clothing storage chamber 111 and improve the drying efficiency. Here, the air cooled by the condensing module 20 flows back to the heating module 10 through the return air duct 30, thereby achieving air internal circulation inside the drying cabinet 100. When the clothes in the clothes storage chamber 111 of the drying cabinet 100 are in a dry state, the dry hot air in the clothes storage chamber 111 flows into the condensing module 20, and the dry cold air cooled by the condensing module 20 flows back to the upper heating module 10 through the return air duct 30, and when the clothes in the clothes storage chamber 111 of the drying cabinet 100 are in a wet state, the humid hot air in the clothes storage chamber 111 flows into the condensing module 20, and the humid hot air is converted into dry cold air after being cooled by the condensing module 20 and condensed water is precipitated, and the dry cold air flows back to the upper heating module 10 through the return air duct 30, and the condensed water is discharged from the condensing module 20.

[0041] For example, Figure 1As shown, the heating module 10 is arranged in the heating chamber 112, which is separated from the clothing storage chamber 111 by an upper partition plate 113, and the condensing module 20 is arranged in the condensing chamber 114, which is separated from the clothing storage chamber 111 by a lower partition plate 115. By providing the upper partition plate 113 and the lower partition plate 115, the clothing storage chamber 111 with a relatively high humidity can be separated from the heating chamber 112 and the condensing chamber 114, so as to prevent the moisture in the clothing storage chamber 111 from adversely affecting the heating module 10 in the heating chamber 112 and the condensing module 20 in the condensing chamber 114 and extend the service life of the drying system 120. In addition, by providing the upper partition plate 113 and the lower partition plate 115, it is also possible to prevent the user from directly seeing the heating module 10 and the condensing module 20 of the drying system 120, thereby improving the appearance of the drying cabinet 100.

[0042] like Figure 3a and Figure 3b As shown, the heating module 10 has a heating element 11, by which the air flowing through can be heated, wherein the heating element 11 can be constructed in the form of a resistance wire in particular. However, other heating elements that are considered meaningful by a person skilled in the art can also be considered. Here, the air heated by the heating element 11 can flow out through the hot air outlet 12 of the heating module 10, and the hot air outlet can pass through the upper partition plate 113 and be arranged at the top or upper side of the clothing storage chamber 111, so that the hot air is located above the clothing storage chamber 111 when it flows out from the hot air outlet 12.

[0043] For example, Figure 2b and Figure 3b As shown, the drying system 120 includes two return air ducts 30, which are arranged along two vertical edges of the drying cabinet 100 located at the rear side in the depth direction Y, which can increase the return air efficiency of the drying system 120 while avoiding the return air ducts from occupying the effective use space of the clothing storage chamber 111. Of course, it is also possible to consider setting other numbers of return air ducts 30 and arranging the return air ducts 30 at other positions that are considered meaningful by those skilled in the art, such as arranging them on the rear wall of the housing 110. Here, the return air duct 30 is preferably constructed in a hollow cylindrical shape, which can avoid the flattened configuration of the return air duct 30 to reduce the resistance caused to the return air flow.

[0044] For example, Figure 1 and Figure 2a As shown, the return air duct 30 is covered by the cover 116 of the housing 110 , thereby preventing the return air duct 30 from being damaged by external forces and preventing the user from directly seeing the return air duct 30 , thereby improving the appearance of the drying cabinet 100 .

[0045] For example, Figure 3a and3b As shown, the drying system 120 further includes a first fan 40, which is configured to promote the circulation of air inside the drying cabinet 100, thereby improving the working efficiency of the drying system 120. In particular, the first fan 40 is arranged upstream of the heating module 10 above the clothing storage chamber 111, and the return air duct 30 is connected from the condensing module 20 to the first fan 40, so that the first fan 40 can blow the cooling air in the return air duct 30 to the heating module 10. However, it is also conceivable that the first fan 40 is arranged at other positions that are considered meaningful by those skilled in the art, such as downstream of the condensing module 20.

[0046] For example, Figure 3a , 3b and Figure 4 As shown, the condensation module 20 includes a heat exchange unit 21 and a cooling unit 22. Here, the heat exchange unit 21 has a return air inlet 211, a first air guide section 212, a second air guide section 213 and a return air outlet 214, wherein the first air guide section 212 and the second air guide section 213 are separately constructed and connected to each other so that the return air inlet 211 and the return air outlet 214 are fluidly connected, wherein the return air inlet 211 leads to the lower side or bottom of the clothing storage chamber 111 to receive the hot and humid air from the clothing storage chamber 111. Of course, other numbers of air guide sections that are considered meaningful by those skilled in the art can also be considered, such as only one integrally constructed air guide section or more air guide sections. Here, at least one of the air guide sections interacts with the cooling unit 22 in a heat conduction manner as a heat exchange element to cool the hot and humid air from the return air inlet 211 and precipitate condensed water, thereby converting the hot and humid air into dry cold air, which is transported to the return air duct 30 via the return air outlet 214. Here, the heat exchange unit 21 and the cooling unit 22 are constructed to be closed relative to each other, so that the air in the heat exchange unit 21 does not mix with the cooling medium in the cooling unit 22, thereby ensuring air circulation inside the drying cabinet 100, which can prevent moisture in the external environment from entering the drying cabinet 100.

[0047] For example, Figure 3a , Figure 3b and Figure 4As shown, the first air guide section 212 and the second air guide section 213 are constructed in a flat plate shape to increase the heat exchange area of ​​each air guide section. Here, the first air guide section 212 and the second air guide section 213 together form a U-shaped configuration, wherein the first air guide section 212 is provided with a curved rotation structure at the lower end, so that the hot and humid air from the return air inlet 211 first flows downward along the height direction Z, changes the flow direction guided at the lower end of the first air guide section 212 and flows upward along the height direction Z to the second air guide section 213, and finally flows out from the return air outlet 214. In this way, the guided flow of air in the heat exchange unit 21 can be achieved. Here, the cooling unit 22 has a cooling air inlet 221 and a cooling air outlet 223 leading to the external environment, and a cooling element 222 is connected between the cooling air inlet and the cooling air outlet.

[0048] For example, Figure 4 As shown, the second air guiding section 213 of the heat exchange unit 21 acts as a heat exchange element, and the cooling element 222 of the cooling unit 22 is integrally constructed with the second air guiding section 213, wherein the cooling element 222 may have at least one, especially multiple cooling air flow channels oriented in the width direction X, and the second air guiding section 213 has at least one, especially multiple return air flow channels oriented in the height direction Z, and the cooling air flow channels and the return air flow channels are alternately arranged spaced apart from each other and interact with each other in a heat conduction manner. This can achieve a sufficiently efficient heat exchange between the second air guiding section 213 as a heat exchange element and the cooling element 222, so as to achieve an optimized condensation effect of the condensation module 20, and can simplify the assembly of the condensation module 20 as a whole. It can also be considered that the first air guiding section 212 of the heat exchange unit 21 acts as a heat exchange element and is integrally constructed with the cooling element 222. It is also possible that the first air-conducting section 212 and the second air-conducting section 213 of the heat exchange unit 21 simultaneously function as heat exchange elements and are each integrally formed with the cooling element 222 .

[0049] For example, it is also possible that the cooling element 222 of the cooling unit 22 is constructed in a flat plate shape and is at least partially arranged between the first air guide section 212 and the second air guide section 213 and is in close contact with the first air guide section 212 and the second air guide section 213, respectively, which can achieve simple and cost-effective manufacturing of the heat exchange unit 21 and the cooling unit 22. In this case, the first air guide section 212 and the second air guide section 213 simultaneously act as heat exchange elements and interact with the cooling element 222 in a heat conduction manner. In addition, when the heat exchange unit 21 has more air guide sections, these air guide sections together form a meandering configuration and cooling elements are arranged between adjacent spaced air guide sections, respectively, to further increase the heat exchange area of ​​the heat exchange element and the cooling element 222 and enhance the condensation effect of the condensation module 20.

[0050] For example, Figure 3a , Figure 3b and Figure 4 As shown, the cooling unit 22 has a cooling air inlet 221 and a cooling air outlet 223 leading to the external environment. The circulating air is cooled by heat exchange between natural air from the external environment and the circulating air inside the drying cabinet 100, thereby realizing the air-cooling working mode of the cooling unit 22.

[0051] For example, Figure 3a , Figure 3b and Figure 4 As shown, the cooling unit 22 further has a second fan 224 , which is configured to promote the flow of cooling air in the cooling unit 22 , thereby improving the condensation efficiency of the condensation module 20 .

[0052] In addition, in the present invention, it can also be considered that the drying system 120 is configured as a heat pump system, wherein the heating module 10 acts as a condenser for the refrigerant, and heats the circulating air by releasing heat through the condensation of the refrigerant, and the condensing module 20 acts as an evaporator for the refrigerant, and absorbs heat through the evaporation of the refrigerant to cool the circulating air, so there is no need to set a cooling air inlet 221 and a cooling air outlet 223 leading to the external environment in the cooling unit 22 of the condensing module 20. The drying system 120 as a heat pump system includes a refrigerant pipeline arranged between the heating module 10 and the condensing module 20 in addition to the return air duct 30 arranged between the heating module 10 and the condensing module 20, and the refrigerant flows in the refrigerant pipeline. In this way, the advantages of high efficiency and energy saving of the heat pump system can be achieved.

[0053] Exemplarily, the condensation module 20 also includes a condensation water outlet 215, which is particularly arranged at the lowermost end of the curved rotating structure of the heat exchange unit 21, such as the first air guide section 212, and the condensation water generated when cooling the circulating air from the clothing storage chamber 111 is discharged to the external environment or the liquid collector via the condensation water outlet, thereby preventing the condensation water from accumulating inside the drying cabinet 100 and adversely affecting the drying effect.

[0054] By way of example, the drying cabinet 100 , in particular the drying system 120 , is constructed substantially completely symmetrically in the width direction X of the drying cabinet 100 , thereby simplifying the construction of the drying system 120 and the installation in the drying cabinet 100 .

[0055] Exemplarily, the drying system 120 further includes a controller, which is configured to be suitable for controlling at least the heating temperature of the heating module 10, so that the user can independently select the drying effect of the clothes in the drying cabinet 100. However, it is also conceivable that the controller is configured to control the humidity in the clothes storage chamber 111 of the drying cabinet 100 and / or the circulation flow speed of the air in the drying cabinet 100. To this end, it is also conceivable that a display device is provided in the drying cabinet 100, and various parameters inside the drying cabinet 100, such as temperature and humidity, are displayed by the display device.

[0056] Exemplarily, a disinfection device can also be provided in the drying cabinet 100. The disinfection device is arranged, for example, downstream of the hot air exhaust port 12. The hot air flow flowing out of the hot air exhaust port 12 can blow the disinfection gas of the disinfection device into the entire clothing storage chamber 111, thereby achieving a comprehensive and effective disinfection effect.

The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated. In specific implementations, multiple features may be combined with each other as required and as technically feasible. Various substitutions, changes, and modifications may also be conceived without departing from the spirit and scope of the present invention.
