Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, specifically providing a condenser tube for a drying system, a drying system, and clothing processing equipment. Background Technology

[0002] Currently, the drying module of a condenser washer-dryer mainly consists of a condenser duct, a fan, a main air duct, and a heater. The condenser duct and the main air duct are connected. The fan and heater are located in the main air duct. During the drying process, the fan rotates, driving air to circulate within the drying module and drum. The specific workflow is as follows: Under the action of the fan, hot dry air in the main air duct blows towards the clothes in the drum, carrying away moisture and forming humid air. This humid air then re-enters the condenser duct, where it exchanges heat and mixes with the condensate. The humid air vaporizes and becomes cold air, which then passes through the heater and becomes hot dry air again, blowing back into the drum. This cycle repeats continuously. During this process, lint is carried into the drying module by the airflow and adheres to the surfaces of components such as the fan and heater. If the lint is not cleaned promptly, it may clog the air duct, reducing the flow area and decreasing airflow, thus affecting the drying effect. Excessive lint accumulation on the heater may ignite, posing a safety hazard.

[0003] In existing technology, for example, publication CN111088678A discloses a condenser duct for washing machines, with the water inlet located on the upper part of the condenser duct, and condensed water flowing down the inner wall. Most washer-dryer combos on the market currently use a similar condenser duct design, but the condensation effect and lint removal efficiency are relatively limited.

[0004] Accordingly, there is a need in the art for a new type of condenser tube, drying system, and garment handling equipment for drying systems to solve the problem of lint accumulation in the air ducts and on the surface of the fan in washer-dryer combos. Summary of the Invention

This invention provides a condenser tube for a drying system. The condenser tube includes a body with a condensing air duct formed within it. The body has an air inlet and an air outlet. The air inlet is located on the side wall of the body. In the width direction of the body, the width of the air inlet is smaller than the width of the condensing air duct. The inner wall of the body is smoothly rounded so that the airflow entering through the air inlet forms a spiral upward airflow along the condensing air duct.

[0027] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0028] It should be noted that in the description of this invention, terms such as "length", "width", "inner", "side", "horizontal", "middle", and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0029] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to 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.

[0030] like Figure 1 As shown in Figure 2, to address the problem of lint accumulation in the air duct and on the fan surface of a washer-dryer combo, this invention provides a condenser tube 1 for a drying system. The condenser tube 1 includes a body 11, within which a condensing air duct 113 is formed. The body 11 has an air inlet 111 and an air outlet 112. The air inlet 111 is located on the side wall of the body 11, and its width is smaller than the width of the condensing air duct 113 in the width direction of the body 11. The inner wall of the body 11 is rounded to allow the airflow entering through the air inlet 111 to form a spiral upward airflow along the condensing air duct 113. It is understood that the length direction of the condenser tube 1 is the upward direction of the airflow in the condensing air duct 113, as shown in Figure 2. Figure 1 The vertical direction of the body 11; the width direction of the body 11 is the direction on the cross-section of the condenser duct 113 that can form a tangential direction with the airflow direction of the air inlet 111, for example, the width direction is Figure 2The direction of the cross-section of the body 11 is the left-right direction; while the direction of the short side of the cross-section of the body 11 is the thickness direction. Of course, the above arrangement is based on the case where the outer edge of the cross-section of the body 11 is a rectangle or a rounded rectangle. When the outer edge of the cross-section of the body 11 is other shapes such as a circle or an ellipse, the directional relationship still follows the above description.

[0031] Because the inner wall of the body 11 is smoothly rounded, the width of the air inlet 111 is smaller than the width of the condenser duct 113. This allows the airflow to continue flowing along the width of the condenser duct 113 after passing through the air inlet 111. This creates conditions for the airflow to rotate within the condenser duct 113. Furthermore, the air inlet 111 is located on the side wall of the body 11, which forces the airflow to enter the condenser duct 113 tangentially to generate a swirling flow. This causes the airflow to spiral upward along the inner wall of the body 11, thereby achieving heat exchange between the humid air and the condensate, as well as the removal of lint (the principle will be explained below).

[0032] like Figure 3 and Figure 4 As shown, this invention proposes a drying system, which includes a condenser pipe 1, a main air duct 2, a fan 3, and a heating air duct 5. The air inlet 111 of the condenser pipe 1 is connected to the drum 7 of the garment processing equipment, and the air outlet 112 of the condenser pipe 1 is connected to the air inlet of the main air duct 2. The main air duct 2 or the condenser pipe 1 is provided with a condensate inlet, and the main air duct 2 is provided with a lint filter 4. The air outlet of the main air duct 2 is connected to the air inlet of the fan 3. The air outlet of the fan 3 is connected to the air inlet of the heating air duct 5, and the heating air duct 5 is provided with a heater 6. The air outlet of the heating air duct 5 is connected to the inner cavity of the drum 7. For ease of description, the garment processing equipment of this invention will be described below using a washer-dryer combo as an example.

[0033] During the drying process of the washer-dryer combo, the fan 3 starts to circulate air, heating the dry, hot air in the air duct into the drum 7. The airflow blows over the clothes in the drum 7, carrying some moisture to form humid, hot air. This humid, hot air, mixed with lint, enters the air inlet 111 of the condenser pipe 1. At this time, condensate is injected through the condensate inlet and flows downward along the main air duct 2 to the condenser duct 113 or directly into the condenser duct 113 and flows downward. Due to the arrangement of the condenser pipe 1 in this invention, the humid, hot air mixed with lint enters the condenser duct 113 through the air inlet 111, forming a spiral upward airflow. Since the condensate flows downward, it is also driven by the spiral airflow... A swirling flow is formed. Due to the significant density difference between the gas and liquid phases, during the mixing process, the condensate is thrown onto the inner wall surface by centrifugal force and then flows downward along the inner wall surface under the action of gravity. The air, with its lower density, moves upward in the central area of ​​the condenser duct 113, thus achieving gas-liquid phase separation. It is through the swirling motion of the condensate and airflow that heat exchange is completed between the two phases. The water vapor in the gas phase liquefies after its temperature decreases and flows downward with most of the condensate. Under the action of centrifugal force, most of the lint is separated and transferred to the water flow. The water flow continues to flow downward and is discharged from the condenser tube 1, thus achieving both heat exchange and lint removal. After condensation, the dry and cold airflow enters the main air duct 2 and passes through the lint filter 4. The remaining small amount of lint in the airflow is filtered and collected. After the lint is removed, the airflow passes through the fan 3 and reaches the heating air duct 5. Under the action of the heater 6, the dry and cold air is heated into dry and hot air. The dry and hot air enters the drum 7 to dry the clothes. This cycle is repeated to achieve the effect of drying clothes.

[0034] The advantages of the above-described configuration are as follows: The condenser tube 1 of this invention can remove most of the lint, thereby reducing the accumulation of lint in the air duct and on the fan surface. Furthermore, the lint filter 4 further cleans the lint, filtering and collecting any remaining lint not removed by the condenser tube 1, thus achieving a better lint cleaning effect. In this case, the condenser tube 1 also reduces the amount of lint on the lint filter 4, thereby extending the replacement time of the lint filter 4 or reducing the occurrence of filter failure due to excessive lint collection. Because the above configuration avoids excessive lint accumulation in the air duct, it not only ensures the required airflow for drying but also eliminates potential safety hazards caused by lint accumulation, improving user experience, increasing reliability, and extending the service life of the washer-dryer. In addition, the condensate in the condenser tube 1 of this invention can exchange heat with the humid air without the need for a flow guiding structure, achieving gas-liquid two-phase separation, eliminating the need for complex structural design and reducing production and operating costs.

[0035] Continue to refer to Figure 1 and Figure 2 In a preferred embodiment, the cross-section of the condenser duct 113 includes two ellipses, and the two ellipses are connected to each other.

[0036] Because the cross-section of the condenser duct 113 includes an ellipse, which is approximately circular, it facilitates airflow rotation around its inner wall, thus making it easier to form a swirling flow. Furthermore, since the cross-section of the condenser duct 113 consists of two connected ellipses, the airflow entering the condenser duct 113 forms two spiraling upward airflows. These two spiral airflows spiral upward around the two elliptical cross-sections of the condenser duct 113. Firstly, the formation of two spiral airflows improves the heat exchange efficiency between the condensate and the humid air, and also enhances the removal of lint. Secondly, it facilitates the overall structural design of the condenser tube 1, making the processing and manufacturing of the air inlet 111 and the body 11, as well as the condenser tube 1 as a whole, easier. Additionally, with the above arrangement, it is possible for the two ellipses to connect at their major axes, increasing the width of the condenser duct 113 and facilitating the formation of spiral airflows. Although the above description describes the condenser duct 113 as having a cross-section comprising two interconnected ellipses, this does not limit the scope of protection of the present invention. The cross-section of the condenser duct 113 can also be other shapes, as long as the airflow can form a spiral airflow within the condenser duct 113. For example, the cross-section of the condenser duct 113 can be circular or elliptical; or the cross-section of the condenser duct 113 can include two circles connected to each other; or the cross-section of the condenser duct 113 can include a combination of a circle and an ellipse connected to each other, all of which can achieve the effect of forming a spiral airflow. Those skilled in the art will understand that the condenser duct 113 formed by the above-mentioned cross-section including circles and / or ellipses includes various forms, such as a straight cylinder, or a funnel shape that gradually widens or narrows from bottom to top, as long as it can form a spiral airflow.

[0037] Continue to refer to Figure 1 and Figure 2 In a preferred embodiment, the air inlet 111 is located in the middle of the side wall of the body 11 in the width direction. Since the air inlet 111 is located in the middle of the side wall of the body 11, the airflow entering the condenser duct 113 from the air inlet 111 will first converge in the middle of the width direction of the condenser duct 113, and then flow along the inner wall to the opposite sides, so that the airflow with a certain tangential velocity can more easily form a swirling flow.

[0038] In a preferred embodiment, the air inlet 111 is located at the bottom of the side wall of the body 11 along its length. Since the air inlet 111 is located at the bottom of the side wall of the body 11, the space below the condenser duct 113 is fully utilized, increasing the upward spiral stroke of the airflow. This increases the heat exchange time between the airflow and the condensate, as well as the time for separating lint, thereby improving the heat exchange effect and the lint removal effect. Furthermore, it reduces the length of the condenser tube 1, thus lowering manufacturing costs.

[0039] Continue to refer to Figure 1 and Figure 2 In a preferred embodiment, the cross-section of the air inlet 111 has two straight lines on opposite sides in the width direction of the body 11; and two arcs on opposite sides in the length direction of the body 11; the straight lines and arcs form the cross-section of the air inlet 111.

[0040] The advantages of the above-described configuration are as follows: the shape of the air inlet 111 is approximately rectangular, which, compared to other shapes such as circles and triangles, reduces the pressure drop within the condenser tube 1 (pressure drop is an important parameter for assessing energy loss; factors such as friction between the airflow and the wall of the condenser duct 113, airflow rotation, and turbulence all affect pressure drop), thus improving separation efficiency. Furthermore, the configuration of the air inlet 111 with two arcs on opposite sides of its cross-section facilitates manufacturing and does not affect the formation of the spiral airflow.

[0041] Furthermore, the ratio of the shortest distance between the two straight lines to the width of the condenser duct 113 is greater than or equal to 0.25 and less than or equal to 0.35; and / or the ratio of the length of the straight line to the shortest distance between the two straight lines (hereinafter referred to as the width) is greater than or equal to 2 and less than or equal to 2.5; and / or when the cross-section of the condenser duct 113 includes an ellipse, the ratio of the length of the major axis to the length of the minor axis of the ellipse is greater than or equal to 1 and less than or equal to 1.6; and / or the ratio of the cross-sectional area of ​​the air inlet 111 to the cross-sectional area of ​​the condenser duct 113 is greater than or equal to 0.4 and less than or equal to 0.7.

[0042] The applicant's research revealed that the aforementioned specific ratio range represents the optimal conditions for the formation of a spiral airflow within the condenser duct 113. For example, under otherwise constant conditions, the ratio of the length to the width of the air inlet 111 determines the magnitude of the pressure drop and the separation efficiency. The pressure drop or separation efficiency fluctuates with the ratio, and a ratio range greater than or equal to 2 and less than or equal to 2.5 allows for an optimal combination of pressure drop and separation efficiency. The principle is similar for other ratios. The combination of the aforementioned optimal ratio ranges provides optimized design for the condenser tubes, improving heat exchange efficiency and lint separation efficiency. It is understood that although this invention is described using the aforementioned ratio ranges, this is not intended to limit the scope of protection of this invention. The specific ratio range can be adjusted as long as it enables the airflow to form a spiral airflow within the condenser duct 113.

[0043] The drying system provided by the present invention includes the condenser tube described in all the above embodiments.

[0044] With this condenser tube, the drying system can filter lint, reducing the accumulation of lint in the air duct and on the fan surface.

[0045] The present invention also provides a garment processing device, which includes the drying system described in the above embodiments. It further includes a drum 7, which is connected to the air inlet 111 of the condenser pipe 1; the air outlet of the heating air pipe 5 is connected to the inner cavity of the drum 7.

[0046] With the aforementioned drying system, this garment processing equipment can collect and filter the lint generated after drying the garments, reducing the accumulation of lint in the air duct and on the fan surface.

[0047] like Figure 5 As shown, and continue to refer to Figure 3 and Figure 4 In a preferred embodiment, the main air duct 2 extends axially along the bottom wall of the cylinder 7 towards the opening of the cylinder 7. A partition 21 is installed inside the main air duct 2, dividing the interior of the main air duct 2 into a main air channel 22. The main air channel 22 forms a bend at the opening, and the lint filter 4 is detachably installed at the bend. Possibly, the air inlet of the main air duct 2 is located at the bottom wall of the cylinder 7, and the air outlet of the main air duct 2 is located on the side wall of the cylinder 7 near the bottom wall. This allows the fan 3 to be positioned on the side wall near the bottom wall, which is beneficial for the layout of the heating air duct 5.

[0048] The airflow entering through the inlet of the main duct 2 first travels along one side of the main duct 22, separated by the partition 21, to the bend at the nozzle side. It then passes through the lint filter 4, which filters the lint. The filtered airflow returns from the bend along the other side of the main duct 22 and reaches the outlet of the main duct 2, before entering the fan 3 through the inlet. The advantage of this arrangement is that placing the lint filter 4 at the bend at the nozzle side allows it to be installed on the front panel of the condenser washer-dryer. Since the lint filter 4 is detachable, for example, it can be pulled out and installed on the front panel, facilitating easy cleaning of the lint within the filter and improving the user experience. Furthermore, the cleaning of lint is completed before it enters the fan 3, thus preventing lint accumulation on the fan of the fan 3. The lint filter device 4 can have various specific structures. For example, it can include a frame and a filter box that can be pulled out of the frame. For instance, a sliding groove can be provided on the frame, and a sliding rail can be provided on the filter box. The sliding groove and the sliding rail are adapted to each other. The frame is fixedly installed at the bend of the main air duct 22. The frame is sealed to the main air duct 2 through a sealing ring. Filter screens are provided on both sides of the filter box, and sponge is filled in the middle. The lint filter device 4 is installed on the front panel through the mounting port of the front panel. Alternatively, it can include a mesh frame mounting base and a filter screen. A slot is defined inside the mesh frame mounting base, and the filter screen can be pulled out and installed in the slot. The mesh frame mounting base is fixedly installed at the bend of the main air duct 22 and sealed to the main air duct 2. It is also installed at the mounting port of the front panel.

[0049] like Figure 6 and Figure 7 As shown, in a preferred embodiment, the volute of the fan 3 gradually increases in both its axial and radial dimensions. In other words, the volute of the fan 3 adopts an axially involute design, meaning that in addition to using an involute curve as its outline in the radial direction, the volute also employs a gradually increasing spacing in the axial direction.

[0050] The advantage of the above arrangement is that, since the dimensions of the volute of the fan 3 gradually increase in both its axial and radial directions, the air volume delivered within the air duct of the fan 3 can be increased, thereby improving the air delivery efficiency. Furthermore, the fan 3 is placed vertically on the cylinder 7, i.e. Figure 4 The outer circumferential side of the volute of the fan 3 shown is attached to the cylinder 7. Due to the complex and compact internal structure of the washer-dryer, components such as motors are often installed in the axial direction of the fan 3, which will occupy the space in the axial direction of the fan 3. The above-mentioned arrangement can ensure the installation stability of the motor and improve the space utilization of the washer-dryer, thus solving the problem of fan 3 placement.

[0051] In a preferred embodiment, the ratio of the axial increase in the size of the volute to the diameter of the fan inside the blower 3 is greater than or equal to 0.2 and less than or equal to 0.4. The ratio of the axial increase in the size of the volute to the diameter of the fan inside the blower 3 has a significant impact on the performance of the blower 3, and the above-mentioned ratio range can both improve the performance of the blower 3 and reduce the noise of the blower 3.

[0052] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0053] For example, in an alternative embodiment, the location of the air inlet 111 is not unique. As long as a spiral airflow can be formed in the condenser duct 113, its location can be adjusted. For example, in the width direction of the body 11, the air inlet 111 can be located at a non-central position on the side wall of the body 11, and in the length direction of the body 11, the air inlet 111 can be located at a lower part of the side wall of the body 11. These locations do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0054] For example, in an alternative embodiment, the shape of the air inlet 111 is not unique. As long as it can form a spiral airflow in the condenser duct 113, it can be designed in other shapes, such as rectangular or trapezoidal shapes. These do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0055] For example, in an alternative embodiment, although the invention is described with the lint filter 4 installed on the front panel of the garment processing equipment, this is not intended to limit the scope of protection of this application. For example, it may be installed only in the main air duct 22, etc., without departing from the principle of the invention, and therefore will fall within the scope of protection of the invention.

[0056] For example, in an alternative embodiment, although the present invention is described as having a volute of the fan 3 with gradually increasing dimensions in both its axial and radial directions, this is not intended to limit the scope of protection of this application. For instance, the volute may only have a gradually increasing dimension in its axial direction, etc., which do not depart from the principle of the present invention and therefore will fall within the scope of protection of the present invention.

[0057] Finally, it should be noted that although this invention is described using a washer-dryer combo as an example, the garment processing equipment of this invention can obviously also be applied to other equipment. For example, the garment processing equipment can also be applied to dryers, etc.

[0058] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
