Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes treatment equipment, and particularly provides a clothes treatment equipment and a drying system for the clothes treatment equipment. BACKGROUND

[0002] The drying system of the heat pump type washer-dryer mainly comprises an air duct and a fan, an evaporator, a condenser and the like arranged in the air duct. In the drying process, the humid air in the drum is driven by the fan into the air duct, the humidity of the humid air is reduced after flowing through the evaporator, and the humid air is changed into dry hot air after flowing through the condenser, the dry hot air enters the drum, and the water on the clothes is carried by the dry hot air and enters the air duct again in the flowing process, so that the clothes are dried through the circulation.

[0003] In the process of drying clothes, lint is inevitably generated from the clothes, and the lint enters the air duct along with the air flow, and then adheres to the surface of the fan, the heat exchanger and the like. If the lint is not cleaned in time, the air duct may be blocked, the flow area is reduced, the air volume is reduced, the drying effect of the clothes is affected, and even an open fire may be caused, which has a safety hazard.

[0004] The existing solution is to set a filter screen upstream of the fan in the air duct, and the lint in the air duct is intercepted by the filter screen. However, the functional area of the existing filter screen is equivalent to the cross-sectional area of the position corresponding to the filter screen in the air duct, the filtering capacity is limited, and the filtered lint is not easy to clean, which is inconvenient to use. SUMMARY

[0005] The present application aims to at least solve one of the above technical problems, i.e., at least solve one of the problems of poor filtering effect and difficulty in cleaning of the filter screen of the existing drying system.

[0006] In a first aspect, the present application provides a drying system for a clothes treatment equipment, characterized in that the drying system comprises an air duct, a filter assembly is arranged in the air duct, the filter assembly comprises at least one filter member, and the filter member comprises at least one filter structure, wherein, in the case that the filter structure comprises a plurality of filter structures, at least a part of the filter structures are non-coplanar, and the filter structure comprises:

[0007] a first portion having a first surface, and a second portion having a second surface, wherein the second surface and the first surface jointly form a blocking portion, so that the lint in the air is trapped to the blocking portion under the joint action of the first surface and the second surface when flowing through the filter assembly.

[0008] The laundry treatment equipment drying system provided by the present application is provided with a filter assembly including at least one filter component in the air duct, each filter component includes at least one filter structure, each filter structure includes a first part with a first surface and a second part with a second surface, the first surface and the second surface are jointly configured to form a blocking part for intercepting lint, the lint in the air is intercepted by the blocking part during the air flow through the filter assembly, thereby achieving the purpose of filtration. The filter component thus configured has a greatly increased area of the region on the filter component that realizes the filtering function, thereby greatly improving the filtering performance of the filter component and improving the filtering effect. In addition, the filter component has a simple structure, is easy to disassemble and assemble, and is more convenient to use.

[0009] The filter assembly provided by the present application can include only one filter component or can include multiple filter components. Each filter component includes at least one filter structure. When the filter structure includes multiple filter structures, at least a part of the adjacent filter structures is non-coplanar. For example, a first part of at least two filter structures is non-coplanar. Further, the first part and the second part of the adjacent two filter structures are both non-coplanar structures. The first part corresponding to the part of the first surface and the second part corresponding to the part of the second surface are jointly configured to form a blocking part for intercepting lint, the blocking part can be a surface formed by connecting only the first surface and the second surface, and can also include a space region sandwiched between the first surface and the second surface. The connection between the first surface and the second surface can be direct cross connection or transition connection through a transition surface.

[0010] For the above-mentioned laundry treatment equipment drying system, in some feasible embodiments, the part of the first surface close to the downstream side along the air flow direction is jointly configured with the second surface to form the blocking part.

[0011] In this way, a configuration form of the blocking part is provided, that is, a part of the first surface is used to jointly configure the blocking part with the second surface, in other words, another part of the first surface is not used to configure the blocking part, but can be used as a part for guiding the air flow, a part for configuring a zigzag channel, and the like. It can be understood that when the width of the first part corresponding to the part of the first surface is greater than the width of the second part, a plurality of position structures are formed, and a plurality of structures of the filter component can be obtained by changing the relative position between the two. For example, the second part can be arranged on the downstream side of the first part corresponding to the first surface, or the second part can be arranged on the position close to the downstream side of the first part corresponding to the first surface.

[0012] For the drying system for a laundry treating apparatus as described above, in some possible implementation, the blocking portion is formed with a lint containing space, and at least part of the trapped lint is attached to the blocking portion at a position corresponding to the lint containing space.

[0013] The blocking portion is configured to intercept the lint in the air. The blocking portion can have various structural forms. For example, the first surface and the second surface are both flat surfaces, and the two surfaces are connected to each other and have an included angle, thereby forming a simple surface structure with an included angle. Alternatively, at least part of the first surface and / or the second surface is a prismatic surface, and the two surfaces are connected to each other to form a chamber structure with a certain space volume. When the blocking portion is formed with the chamber structure, the chamber structure serves as the lint containing space for containing the lint. Since the chamber structure can contain more lint, the lint can be enriched in the chamber, thereby improving the filtering performance of the filtering member.

[0014] For the drying system for a laundry treating apparatus as described above, in some possible implementation, the second portion extends from a downstream side of the first surface along the air flow direction, and the second surface is formed on a side of the second portion opposite to the first surface.

[0015] In this way, a specific implementation of the second portion is provided. When the second portion is arranged at the downstream side of the first surface along the air flow direction, the functional area of the filtering member can be increased, thereby improving the filtering effect. It can be understood that the second portion can also be arranged at a position close to the downstream side of the first surface. The functional area refers to an area directly contacted by the air flow during the process of trapping the lint.

[0016] For the drying system for a laundry treating apparatus as described above, in some possible implementation, the second portion includes a main body portion, and the main body portion extends from the downstream side of the first surface along the air flow direction.

[0017] In this way, a specific implementation of the second portion is provided.

[0018] For the drying system for a laundry treating apparatus as described above, in some possible implementation, an edge of the main body portion further extends towards the first surface to form a flange.

[0019] By arranging the flange, the lint entering the lint containing space can be further intercepted, and the probability that the enriched lint is carried away by the subsequent air flow can be reduced, thereby further improving the filtering effect of the filtering member.

[0020] For the drying system for a laundry treating apparatus as described above, in some possible implementation, the filtering member is configured with a flushing member to clean the filtering member by flushing.

[0021] By configuring the filter member with the flushing member, the filter member can be conveniently cleaned, the disassembly operation required for manual flushing is avoided, and the use convenience is improved.

[0022] For the above-mentioned drying system for a clothes treatment apparatus, in some possible embodiments, the filter member is arranged obliquely relative to a horizontal plane, so as to guide the flow of the flushing medium in the blocking portion by means of the oblique arrangement.

[0023] By arranging the filter member obliquely relative to the horizontal plane, not only the functional area of the filter member can be further increased, thereby improving the filtering performance of the filter member, but also the flow of the flushing medium in the blocking portion can be guided by means of the oblique position, so as to avoid water accumulation and improve the flushing efficiency.

[0024] For the above-mentioned drying system for a clothes treatment apparatus, in some possible embodiments, the drying system comprises a sewage discharge channel, and the flushing medium is guided to the sewage discharge channel through the filter member.

[0025] By arranging the sewage discharge channel, the sewage after flushing can be smoothly discharged. The sewage discharge channel can be arranged in various ways, for example, a channel for discharging the sewage generated by flushing the filter member can be arranged outside the drum, or the sewage discharge channel can be integrated in the air duct, etc.

[0026] In a second aspect, the present application further provides a clothes treatment apparatus, which is configured with the above-mentioned drying system for a clothes treatment apparatus.

[0027] It can be understood that, since the clothes treatment apparatus is configured with the above-mentioned drying system for a clothes treatment apparatus, all the technical effects that can be achieved by the above-mentioned drying system are possessed, which will not be described herein again.

DETAILED DESCRIPTION

[0037] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application. For example, although the following embodiments are explained in combination with a washer-dryer, this is not limiting, and the technical solutions of the present application are also applicable to a dryer, and the change of the application object does not deviate from the principles and scope of the present application.

[0038] In addition, in order to better illustrate the present application, numerous specific details are given in the following detailed description. It should be understood by those skilled in the art that the present application can also be implemented without some specific details.

[0039] In the description of the present application, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like, which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", "fourth" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0040] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] This invention provides a washer-dryer combo 1, which includes a housing, within which a drying system and a drum assembly 10 are disposed. The drying system includes an air duct assembly 20, a fan assembly 30, a heat exchanger, etc. The fan assembly 30 includes a volute and a fan and motor disposed within the volute. The heat exchanger includes a condenser and an evaporator, which are connected by a pipeline. The pipeline is also connected to a compressor, an expansion valve, etc., to form a refrigerant circuit for refrigerant circulation. The air duct assembly 20 includes multiple air duct components, which are connected to form an air duct for air circulation. The fan assembly 30 and the heat exchanger are disposed within the air duct. The drum assembly 10 includes an outer drum and an inner drum. The outer drum is fixedly disposed relative to the housing, and the inner drum is rotatably disposed within the outer drum. The drum opening 101 of the drum assembly 10 is for the user to load and unload clothes.

[0042] The air duct assembly 20 forms an air duct for air circulation outside the cylinder. In this embodiment, the air duct assembly 20 includes a first air duct component 210, a second air duct component 220, a third air duct component 230, and a fourth air duct component 240. Figures 1-4 As shown, the fourth air duct component 240, the first air duct component 210, the volute, the second air duct component 220, and the third air duct component 230 are connected sequentially to form an air duct for air circulation. The evaporator and condenser are located within the second air duct component 220. Viewed along the airflow direction, the evaporator is located upstream of the condenser. During the airflow through the heat exchanger, the air is first dehumidified at the evaporator and then heated at the condenser. Because the evaporator has a higher ability to adsorb lint than other components, a first flushing component 50 is separately configured for the evaporator in this embodiment. The flushing wastewater is discharged along with the condensate from the evaporator through the condensate pipe 40.

[0043] Specifically, the back of the outer drum is formed with an outlet for the air in the drum to flow out, the outlet is connected with one end of the fourth air duct member 240, the other end of the fourth air duct member 240 is connected with the air inlet 2101 of the first air duct member 210, the air outlet 2106 of the first air duct member 210 is connected with the air inlet of the volute, the air outlet of the volute is connected with the air inlet of the second air duct member 220, the air outlet of the second air duct member 220 is connected with the air inlet of the third air duct member 230, and the air outlet of the third air duct member 230 is connected to the air inlet of the drum assembly 10, which is located at the top of the drum opening 101. By arranging the drum assembly 10 and the air duct assembly 20 in this way, an air duct for circulating and flowing air can be formed, and the air in the drum enters the formed air duct from the back outlet of the drum under the action of the fan, and then changes into dry hot air after being dehumidified and heated in the air duct. Then the dry hot air enters the drum through the air inlet of the drum assembly 10 to dry the clothes, and in the process, the moisture and lint on the clothes are removed and enter the air duct again for the next cycle.

[0044] It can be understood that the structure of the air duct assembly 20 described above is only exemplary. For example, the fourth air duct member 240 and the first air duct member 210 can be arranged as an integrated structure, or the second air duct member 220 and the third air duct member 230 can be arranged as an integrated structure, or the second air duct member 220 can be arranged as a split structure, etc.

[0045] Referring to FIGS. 1, 2 and 3, Figure 1 , Figures 3-5 As shown in FIGS. 1, 2 and 3, the first air duct member 210 in the embodiment is vertically arranged behind the drum assembly 10, and has a hollow chamber. A filter assembly 60 is arranged inside the first air duct member 210, which filters the circulating air to trap lint in the air and prevent the lint from adhering to the fan, heat exchanger, etc.

[0046] The drying system for the clothes treatment equipment provided by the present application is provided with a filter assembly 60 including at least one filter member in the air duct, each filter member includes at least one filter structure, each filter structure includes a first part 6110 and a second part 6120, the first part 6110 has a first surface 61101, and the second part 6120 has a second surface. The first surface 61101 and the second surface together form a blocking part for trapping lint. During the air flow through the filter assembly 60, the lint in the air is trapped by the blocking part, thereby achieving the purpose of filtering. The filter member thus formed has a much larger area for filtering than the existing filter screen structure, thereby greatly improving the filtering performance of the filter member and the filtering effect. In addition, the filter member has a simple structure, is easy to disassemble and assemble, and is more convenient to use.

[0047] The filtering assembly 60 provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0048] The filtering assembly 60 in the present application comprises at least one filtering member. When the number of filtering members is plural, each filtering member is arranged in a direction perpendicular or approximately perpendicular to the air flow direction. The filtering assembly 60 is arranged in the air duct, and the projection of the filtering members contained in the filtering assembly 60 on the air duct section can almost cover the air duct section. When the number of filtering members is plural, the air mainly flows in the tortuous passage formed between the adjacent two filtering members, and the lint in the air is intercepted by the blocking part of the filtering member during the air flowing through the tortuous passage. The structure of the tortuous passage is shown in Figure 6 .

[0049] Referring to Figure 3 , Figure 5 and Figure 6 , the filtering assembly 60 provided by the embodiment comprises two filtering members, i.e. a first filtering member 610 and a second filtering member 620. The first filtering member 610 and the second filtering member 620 have the same structure, and are arranged in a direction perpendicular to the air flow direction. In order to better understand, the orientation of the first filtering member 610 and the second filtering member 620 will be taken as an example, and the first filtering member 610 and the second filtering member 620 are arranged in a direction perpendicular to the paper plane. Figure 3

[0050] It can be understood that the first filtering member 610 and the second filtering member 620 can also have other structural forms, for example, only the second part 6120 extending from the first surface 61101 is arranged on the side of the first filtering member 610 and the second filtering member 620 opposite to each other, and the second part 6120 is not arranged on the side of the first filtering member 610 and the second filtering member 620 opposite to each other, and the edges of the side of the first filtering member 610 and the second filtering member 620 opposite to each other abut against the inner wall surface of the air duct during installation, so that the air mainly flows in the tortuous passage formed between the adjacent filtering members. Preferably, the number of filtering members is 2-5, so that the tortuous passage formed is 1-4, so that the filtering assembly 60 can have high filtering capacity and will not excessively hinder the air flow.

[0051] ​Each filter member includes at least one filter structure. When each filter member includes a plurality of filter structures, at least some of the filter structures are non-coplanar. Specifically, each filter structure includes a first portion 6110 and a second portion 6120 which are connected to each other or formed as an integral structure. The present application does not limit the specific structure of the first portion 6110, for example, the first portion 6110 can be a flat plate structure, an arc-shaped plate structure, a triangular prism structure, etc., on which a first surface 61101 is formed, the first surface 61101 is mainly used to construct a tortuous passage, and to construct a barrier portion for trapping dust, and in addition, the first surface 61101 also has the function of guiding the air flow. The second portion 6120 is provided on the downstream side of the first portion 6110 in the air flow direction, and the second portion 6120 has a second surface which, together with the portion of the first surface 61101 on the downstream side, constructs the aforementioned barrier portion. The present application does not limit the specific structure of the second portion 6120, for example, the second portion 6120 can be a flat plate structure, a bent plate structure, etc., as long as the second surface thereof can construct the barrier portion with the first surface 61101.

[0052] Specifically, as Figure 6As shown, the first filter member 610 is exemplified as including five filter structures connected with each other to form an integrated structure. Each filter structure includes a first portion 6110 and a second portion 6120 extending from a downstream side of a first surface 61101 of the first portion 6110. The first portion 6110 is in a flat plate structure, and the first surface 61101 is located at a windward side of the first portion 6110. The second portion 6120 is in a bent plate structure. The second portion 6120 includes a main body portion 61201, which in this embodiment includes a first main body portion (not labeled) extending from the first surface 61101 and a second main body portion (not labeled) extending from an outer edge of the first main body portion. A surface of the first main body portion adjacent to the first surface 61101 is defined as a first sub-surface (not labeled), and the first sub-surface and the first surface 61101 have an included angle therebetween, which is an acute angle. A surface of the second main body portion opposite to the first surface 61101 is defined as a second sub-surface (not labeled), and the second sub-surface is parallel to the first surface 61101. The first sub-surface and the second sub-surface together form a second surface in the present application. In this embodiment, a portion of the first surface 61101, the first sub-surface, and the second sub-surface together form a blocking portion. Since the air flowing in the air duct during the drying process is humid air, the surface of the blocking portion is kept wet, thereby having a certain adsorption capacity. When the humid air enters the blocking portion under the guidance of the first surface 61101, the airflow is blocked and changes direction, and in this process, the humid air carrying the lint collides with the surface of the blocking portion, thereby causing the lint in the air to adhere to the surface of the blocking portion, and the lint is trapped, thereby achieving a filtering effect.

[0053] It can be understood that the included angle between the first main body portion and the first surface 61101 is only exemplary, and the included angle therebetween can also be a right angle or an obtuse angle. The second main body portion and the first surface 61101 can also have an included angle therebetween. In summary, the first surface 61101, the first sub-surface, and the second sub-surface can have any positional relationship therebetween, as long as a blocking portion that can trap the lint can be formed. It can also be understood that the main body structure of the second portion 6120 described above is also exemplary, and the main body structure can be connected by a plurality of plate structures. Further, the edge of the second main body portion further extends to form a flange 61202 extending toward the first surface 61101, to further enhance the ability to block the lint. The flange 61202 is perpendicular or approximately perpendicular to the portion of the second surface parallel to the first surface 61101.

[0054] Furthermore, when the filter component includes at least two filter structures, such as a first filter structure and a second filter structure, the first filter structure is the same as the second filter structure, and the downstream side of the first filter structure is connected to the upstream side of the second filter structure, then the first part 6110 of the first filter structure and the first part 6110 of the second filter structure are not coplanar, and they have an included angle, which ranges from 90° to 150°.

[0055] like Figure 6 As shown, when the first part 6110 is parallel to the second main body of the second part 6120, viewed along the airflow direction, the size of the first part 6110 is larger than the size of the second part 6120. This size refers to the distance between the root of the first part 6110 extending to form the second part and its free end in a filter structure. The size of the second part 6120 is measured in the same way. To obtain a better filtration effect, the size of the second part 6120 is set to 25% to 50% of the size of the first part 6110, such as 30%. Furthermore, the distance between the second sub-surface and the first surface 61101 is 6 to 8 mm, such as 6 mm. This maximizes the trapping of lint in the air without excessively obstructing airflow.

[0056] To facilitate the removal of lint trapped in the filter assembly 60, the filter assembly 60 of this invention is also equipped with a flushing component, allowing for cleaning of the filter assembly 60 through flushing. It is understood that the filter assembly 60 can also be cleaned by manual disassembly and assembly. (Refer to...) Figure 3 and Figure 4 As shown, in this embodiment, the filter assembly 60 is connected to a second flushing member 70, which is connected to one side wall of the first air duct member 210, for example, by plugging or snapping. The second flushing member 70 has a chamber 701, and one end of the filter member passes through the side wall of the second flushing member 70 corresponding to the chamber 701 and extends into the interior of the chamber 701. The chamber is also connected to a water inlet 702, which is connected to a water inlet pipe. When water enters the chamber 701 through the water inlet 702, the water in the chamber 701 can enter the lint-receiving space formed by the first surface 61101 and the second surface structure from the end of the filter member corresponding to the chamber 701, thereby flushing the lint on the surface of the blocking part and cleaning the filter assembly 60.

[0057] Furthermore, to facilitate smooth water flow, the filter components are installed at an angle of 0–45° relative to the horizontal plane. Figure 3As shown in the figure, the height of the right end of the filter member is higher than the height of the left end, and the filter member is inclined from the right top to the left bottom. In the case of water inflow at the right end, the water flow can smoothly flow to the left end under the guidance of the inclined filter member, thereby improving the cleaning efficiency.

[0058] It can be understood that the flushing medium can be clean water, washing water, etc.

[0059] In the prior art, the drying system is provided with a pipeline for discharging condensate water, and the bottom of the cylinder assembly 10 is provided with a sewage discharge pipeline 80. The condensate water pipeline 40 is connected to the sewage discharge pipeline 80 at the bottom, so that the condensate water is discharged to the outside of the all-in-one machine along with the sewage discharge pipeline 80. In the embodiment of the present application, the sewage discharge passage 2103 and the air passage 2104 are formed in the first air duct member 210. Most of the filter assembly 60 is arranged in the air passage 2104, one end of the filter member extends into the chamber of the second flushing member 70, and the other end extends into the sewage discharge passage 2103. In this way, the flushing medium for flushing the wire scraps can enter the sewage discharge passage 2103 under the guidance of the filter member, and the sewage discharge passage 2103 is in communication with the sewage discharge pipeline 80 at the bottom of the cylinder, so that the sewage can be discharged to the outside of the all-in-one machine. Referring to Figure 3 As shown in the figure, the inside of the first air duct member 210 is isolated to form a sewage discharge passage 2103 for sewage flow, and the top of the sewage discharge passage 2103 is provided with a condensate water inlet 2105, and the bottom is provided with a sewage discharge port 2102 connected to the external environment through the sewage discharge pipeline 80. In order to shorten the length of the condensate water pipeline 40, the water outlet end of the condensate water pipeline 40 is connected to the condensate water inlet 2105 of the sewage discharge passage 2103. It can be understood that the water outlet end of the condensate water pipeline 40 can also be connected to the water inlet of the second flushing member 70, and the generated condensate water is used to flush the filter member, thereby improving the utilization rate of resources.

Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
