Description

Technical Field

[0001] This application relates to the field of garment processing equipment technology, and in particular to a washer-dryer combo machine. Background Technology

[0002] With social progress and technological development, washer-dryer combos have become common household appliances. As living standards improve at a fast pace, people are using washer-dryer combos more frequently and have increasingly higher requirements for their drying performance.

[0003] In washer-dryer combos, the drying structure consists of a drying duct, a heating element, a fan, and a condenser. During operation, the heating element heats the air to create hot air. This hot air enters the drum, penetrates the clothes, and becomes humid air. This humid air exits the drum and is condensed into water by the condenser, then discharged. This cycle repeats multiple times to dry the clothes. The condenser's efficiency directly affects the efficiency with which the moisture in the humid air is condensed and discharged, thus affecting dehumidification efficiency. If the dehumidification efficiency is low, the hot air re-entering the drum will have a high moisture content, making it easier for the air to reach saturated vapor pressure, which is detrimental to the evaporation of moisture from the clothes and hinders rapid drying. Utility Model Content

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this application provides the following technical solutions:

[0005] An embodiment of this application provides a washer-dryer combo, comprising: a housing with a clothing inlet on its front surface; an outer drum disposed within the housing, the outer drum having an opening on its front end opposite to the clothing inlet, and an air outlet on its rear wall; an inner drum disposed within the outer drum and capable of rotating within the outer drum, forming a clothing processing chamber for accommodating clothing; a drying duct disposed on the outer surface of the outer drum, one end of the drying duct communicating with the air outlet, and the other end of the drying duct extending to the front end of the clothing processing chamber and communicating with the clothing processing chamber; and a condenser tray disposed within the drying duct and adjacent to the air outlet; wherein the condenser tray includes two heat-conducting plates and a heat-absorbing medium, a closed thermal superconducting channel is formed between the two heat-conducting plates, the heat-absorbing medium is located within the thermal superconducting channel, and the thickness of the portion of the heat-conducting plate forming the thermal superconducting channel is less than the thickness of other portions.

[0006] The washer-dryer provided in this application has a thermal superconducting channel in its condenser tray. This channel has extremely high thermal conductivity and can respond rapidly to changes in heat. It can quickly absorb heat from the humid air entering the drying duct from the inner drum, causing the moisture in the humid air to condense into water, thus improving the dehumidification efficiency of the product and achieving rapid drying of clothes. In addition, because the channel wall of the thermal superconducting channel is relatively thin, on the one hand, the time for heat transfer through the channel wall is shortened, and the response speed of the thermal superconducting channel to changes in heat is accelerated, further improving the thermal conductivity of the thermal superconducting channel. On the other hand, the thinner channel wall can significantly reduce the thermal resistance during heat transfer, thereby enabling smoother heat exchange and further improving the thermal conductivity of the thermal superconducting channel.

[0007] In some embodiments, a gap exists between the condenser plate and the drying duct.

[0008] In the above technical solution, the gap is used to allow the cooling medium to pass through, so as to ensure that the cooling medium effectively cools the condenser plate, thereby enabling the condenser plate to effectively dehumidify the hot and humid air, thus ensuring the dehumidification efficiency of the product and achieving rapid drying of clothes.

[0009] In some embodiments, the two ends of the condenser plate are respectively connected to two duct walls opposite to the drying duct, and the condenser plate is inclined relative to the duct walls.

[0010] In the above technical solution, the inclined condenser plate allows the hot and humid air entering the drying air duct to "collide" with the condenser plate, changing the flow direction of the hot and humid air in the duct and increasing the flow path length of the hot and humid air in the duct. This increases the contact time between the hot and humid air and the condenser plate, ensuring that the condenser plate fully dehumidifies the hot and humid air.

[0011] In some embodiments, the edge of the condenser plate is bent toward the direction of the air outlet so that the condenser plate is arc-shaped as a whole.

[0012] In the above technical solution, after the hot and humid air enters the arc-shaped condenser plate, it will form a circulating air area, which will disrupt the flow of the hot and humid air and further prolong the residence time of the hot and humid air on the surface of the condenser plate. That is, it increases the contact time between the hot and humid air and the condenser plate, so as to ensure that the condenser plate can fully dehumidify the hot and humid air.

[0013] In some embodiments, the condenser plate is provided with a plurality of through holes extending through it in the extending direction of the drying air duct.

[0014] In the above technical solution, the through holes allow hot and humid air to pass directly through the condenser plate, increasing the contact area between the hot and humid air and the condenser plate, thereby effectively improving the heat exchange efficiency and ensuring that the condenser plate fully dehumidifies the hot and humid air.

[0015] In some embodiments, the drying duct includes: a duct shell, one end of which is connected to the air outlet and the other end of which is connected to the clothing processing chamber, the duct shell having an opening; and a condenser tray, the condenser tray being detachably disposed at the opening and sealing the opening.

[0016] In the above technical solution, the condenser tray is integrated into the drying air duct, which reduces the space required for setting up a separate condenser tray, thus reducing the spatial size of the drying air duct and the volume of the washer-dryer combo.

[0017] In some embodiments, at least one of the two heat-conducting plates is provided with a groove, the groove and the surface of the other heat-conducting plate forming the thermal superconducting channel.

[0018] In the above technical solution, protrusions are formed on the outer surface of one or two heat-conducting plates. The protrusions can increase the contact area between the hot and humid air and the condenser plate, thereby effectively improving the heat exchange efficiency and ensuring that the condenser plate fully dehumidifies the hot and humid air.

[0019] In some embodiments, the condensation plate has a plurality of connection points connecting the two heat-conducting plates, and the thermal superconducting channel is arranged around the connection points.

[0020] In the above technical solution, while ensuring connection strength, the connection area of ​​the connection points is small. Since the thermal superconducting channels form a network around these connection points, the flow area of ​​the thermal superconducting channels is effectively increased. This allows the condenser to have more heat-absorbing medium, increasing the heat absorption capacity of the condenser. Consequently, the condenser can respond quickly to changes in heat, effectively improving heat exchange efficiency and ensuring that the condenser can fully dehumidify the humid air.

[0021] In some embodiments, the washer-dryer further includes a spray pipe inserted into the drying duct and positioned toward the condenser tray, the spray pipe being configured to deliver coolant to the condenser tray.

[0022] In the above technical solution, liquid cooling is used to cool the condenser plate. Since liquid has a large specific heat capacity, it can quickly cool the condenser plate, thereby improving the heat exchange efficiency between the condenser plate and the humid air in the condensation chamber. At the same time, the coolant can also directly exchange heat with the humid air in the condensation chamber to condense and dehumidify the humid air, thereby improving the condensation efficiency and drying efficiency.

[0023] In some embodiments, the drying duct includes a condensing chamber and a heating chamber, the condensing plate is disposed in the condensing chamber, and a turbulence structure is disposed in the condensing chamber, the turbulence structure being configured to change the flow direction of the hot and humid air.

[0024] In the above technical solution, the turbulence structure can generate turbulence in the humid and hot air in the drying duct, increase the contact frequency between the humid and hot air and the condenser plate, thereby effectively improving the heat exchange efficiency and ensuring that the condenser plate fully dehumidifies the humid and hot air.

[0057] In the description of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, and other dimensions of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0058] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0059] like Figures 1 to 15 As shown (the arrows in the figure indicate the direction of gas flow), the washer-dryer provided in this application includes: a housing 10, an outer drum 20, an inner drum 30, a drying air duct 50, and a condenser tray 40.

[0060] like Figures 1 to 3 As shown, the front surface of the housing 10 has a clothing inlet 12. Specifically, the housing 10 typically adopts a rectangular hollow structure. As the outer shell of the washer-dryer combo, its shape can be designed as needed. The internal space of the housing 10 provides installation space for components such as the outer drum 20 and inner drum 30. The clothing inlet 12 on the front surface of the housing 10 connects to the installation space inside the housing 10. A door 11 is located on the front side of the housing 10, which is used to open and close the clothing inlet 12 on the front side of the housing 10, thereby opening and closing the installation space inside.

[0061] like Figures 1 to 3 As shown, the outer drum 20 is disposed inside the housing 10. The front face of the outer drum 20 has an opening opposite to the clothing inlet 12, and the rear wall of the outer drum 20 has an air outlet 21. Specifically, the outer drum 20 is disposed within the installation space of the housing 10 and is relatively fixed inside the housing 10. The outer drum 20 is a shell structure with an opening, the opening of which faces the clothing inlet 12 on the front side of the housing 10. The outer drum 20 is constructed to hold washing water; that is, the internal space of the outer drum 20 can be used to hold washing liquid.

[0062] like Figures 1 to 3 As shown, the inner drum 30 is disposed inside the outer drum 20 and can rotate within the outer drum 20. A garment processing chamber for holding clothes is formed within the inner drum 30. Specifically, the inner drum 30 is rotatably disposed within the internal space of the outer drum 20, and a garment processing chamber is formed within the inner drum 30 for holding clothes to be washed. The opening of the inner drum 30 is directly opposite the opening of the outer drum 20, that is, the front opening of the garment processing chamber is directly opposite the opening of the outer drum 20 and the garment inlet 12. Therefore, clothes can sequentially enter the garment processing chamber from the garment inlet 12 of the housing 10, the opening of the outer drum 20, and the opening of the inner drum 30. The outer drum 20 and the inner drum 30 are arranged coaxially inside and outside. Holes are provided on the outer wall of the inner drum 30, allowing water from the outer drum 20 to enter the inner drum 30 through these holes to wash the clothes in the garment processing chamber of the inner drum 30. At the same time, during the drying process, the air in the clothes handling chamber of the inner drum 30 can also enter the internal space of the outer drum 20 through the hole.

[0063] like Figures 1 to 3As shown, the drying air duct 50 is disposed on the outer surface of the outer cylinder 20. One end of the drying air duct 50 is connected to the air outlet 21, and the other end of the drying air duct 50 extends to the front end of the clothing processing chamber and is connected to the clothing processing chamber. Specifically, the portion of the drying air duct 50 located on the rear wall of the outer cylinder 20 is arranged around the axis of the outer cylinder 20 to ensure that the drying air duct 50 has a longer path, thereby increasing the duration of the flow of hot and humid air in the drying air duct 50.

[0064] like Figures 4 to 8 As shown, the condenser plate 40 is installed inside the drying air duct 50 and adjacent to the air outlet 21.

[0065] The condenser plate 40 includes two heat-conducting plates 41 (the material of the heat-conducting plates 41 should be a material with good thermal conductivity; specifically, the material of the heat-conducting plates 41 can be at least one of stainless steel, copper, copper alloy, aluminum, aluminum alloy, titanium, and titanium alloy) and a heat-absorbing medium 42 (the heat-absorbing medium 42 is a gas-liquid mixture with a low boiling point (<20℃). When the condenser plate 40 encounters humid and hot air (the temperature of humid and hot air is generally between 20 and 65℃, and the humidity is between 40 and 90%), the liquid heat-absorbing medium 42 can quickly absorb heat and turn into a gaseous state). A closed thermal superconducting channel 43 is formed between the two heat-conducting plates 41. The heat-absorbing medium 42 is located inside the thermal superconducting channel 43. The thickness of the part of the heat-conducting plate 41 that forms the thermal superconducting channel 43 is less than the thickness of other parts.

[0066] The washer-dryer provided in this application, when hot and humid air flows through the condenser plate 40, because the thermal superconducting channel 43 covers the entire surface of the condenser plate 40 and has the characteristics of high heat transfer rate and high heat transfer density, the condenser plate 40 can respond quickly to changes in heat, so that the heat is quickly and evenly distributed on the entire condenser plate 40, increasing the temperature difference between the condenser plate 40 and the air and the effective heat transfer area, greatly improving the heat dissipation capacity and heat exchange efficiency of the condenser plate 40, and can quickly absorb the heat in the hot and humid air, so that the moisture in the hot and humid air condenses into water, thereby improving the dehumidification efficiency of the product and achieving rapid drying of clothes.

[0067] In addition, because the channel wall of the thermal superconducting channel 43 is relatively thin, on the one hand, the thin channel wall can shorten the heat transfer time, that is, heat can be transferred quickly through the thin channel wall, enabling the thermal superconducting channel 43 to respond more quickly to temperature changes, and further improving the thermal conductivity of the thermal superconducting channel 43; on the other hand, the thinner channel wall means that the resistance encountered by heat during the transfer process is smaller, allowing heat to be transferred through the channel wall more quickly and efficiently, thereby enabling smoother heat exchange, reducing the accumulation of heat on the channel wall, and further improving the thermal conductivity of the thermal superconducting channel 43.

[0068] Those skilled in the art will understand that, in addition to the above-described structure, washer-dryer combos also include heating components disposed within the drying duct 50, cooling devices for cooling the condenser tray 40, etc., which will not be listed here. In one embodiment of this application, the heating components include a heater 91 and a fan 92. The heater 91 heats the air dehumidified by the condenser tray 40, generating high-temperature air within the drying duct 50. The fan 92 provides airflow, allowing the high-temperature air within the drying duct 50 to enter the clothing processing chamber of the inner drum 30, drying the clothing within the chamber. In one embodiment of this application, the cooling device cools the condenser tray 40 after heat absorption, ensuring that the condenser tray 40 can continuously and effectively cool and dehumidify the hot and humid air.

[0069] like Figure 7 and Figure 8 As shown, in one embodiment of this application, the condenser plate 40 has a plurality of connection points 44 connecting the two heat-conducting plates 41, and the thermal superconducting channel 43 is arranged around the connection points 44.

[0070] While ensuring connection strength, the connection area of ​​connection point 44 is relatively small. Since the thermal superconducting channel 43 forms a network around these connection points 44, the flow area of ​​the thermal superconducting channel 43 is effectively increased. Even if the condensing plate 40 has more heat-absorbing medium 42, the heat absorption capacity of the condensing plate 40 is increased, thereby enabling the condensing plate 40 to respond quickly to changes in heat, effectively improving heat exchange efficiency, and ensuring that the condensing plate 40 fully dehumidifies the humid and hot air.

[0071] like Figures 1 to 9 As shown, the drying process of the washer-dryer combo is as follows: the heating element heats the air and allows the hot air to enter the inner drum 30; the hot air passes through the clothes in the inner drum 30, causing the moisture on the clothes to evaporate, and the air in the inner drum 30 becomes humid hot air. The humid hot air enters the drying air duct 50 through the air outlet 21 set on the rear wall of the outer drum 20. The humid hot air rises in the drying air duct 50. During the upward movement, the condenser plate 40 quickly condenses the moisture in the humid hot air to form condensate, and the humid hot air becomes dry cold air. The condensate is discharged to the bottom of the outer drum 20 through the drain outlet below the condenser plate 40, and the water in the outer drum 20 is drained away through the drainage device; the dry cold air is heated by the heating element and re-enters the clothes in the inner drum 30. This cycle is repeated to dry the clothes.

[0072] like Figure 10 As shown, in one embodiment of this application, the two ends of the condenser plate 40 are respectively connected to two air duct walls that are opposite to the drying air duct 50, and the condenser plate 40 is inclined relative to the air duct wall.

[0073] The inclined condenser plate 40 allows the hot and humid air entering the drying duct 50 to "collide" with it, altering the airflow direction within the duct. This creates disturbance during airflow, facilitating mixing between airflows of different temperatures and humidity levels, resulting in a more uniform temperature and humidity field within the drying duct 50 and further improving drying efficiency. Furthermore, the longer airflow path increases the contact time with the condenser plate 40, promoting more efficient heat exchange and enhancing the cooling effect of the condenser plate 40 on the hot air, thus improving the overall heat exchange efficiency of the drying system. Additionally, the airflow may form localized vortices, increasing the heat transfer coefficient between the airflow and the surface of the condenser plate 40, further strengthening the heat exchange process, improving condensation efficiency, reducing humidity in the hot air, and enhancing drying quality.

[0074] like Figure 11 As shown, in one embodiment of this application, the edge of the condenser plate 40 is bent toward the direction close to the air outlet 21 so that the condenser plate 40 is arc-shaped as a whole.

[0075] On the one hand, the hot and humid air entering the arc-shaped condenser plate 40 forms a circulating airflow area, disrupting the airflow and further prolonging the residence time of the hot and humid air on the surface of the condenser plate 40. This increases the contact time between the hot and humid air and the condenser plate 40, allowing for more thorough heat exchange. This improves the cooling effect of the condenser plate 40 on the airflow, promotes the condensation of moisture in the airflow, reduces the humidity of the airflow, and thus improves drying efficiency and quality, ensuring that the condenser plate 40 effectively dehumidifies the hot and humid air. On the other hand, the arc-shaped condenser plate 40 allows condensate to flow more smoothly along the arc surface to a specific location under the influence of gravity. Compared to a flat condenser plate 40, the arc design reduces the retention and diffusion of condensate on the plate surface, helps to concentrate and collect condensate, and facilitates its discharge through the drainage system, thus preventing condensate from flowing back or dripping into the drying duct 50 and affecting the drying effect.

[0076] like Figure 12 As shown, in one embodiment of this application, there is a gap 60 between the condenser plate 40 and the drying air duct 50, that is, there is a gap 60 between the rear surface of the condenser plate 40 and the drying air duct 50, and the humid and hot air contacts the front surface of the condenser plate 40.

[0077] The gap 60 is used for the passage of cooling medium. The flow of cooling medium in the gap 60 can promptly remove the heat from the rear surface of the condenser plate 40, maintaining a large temperature difference between the front and rear surfaces of the condenser plate 40. This facilitates faster and more complete condensation of moisture in the hot and humid air on the front surface of the condenser plate 40, improving condensation efficiency. As a result, the condenser plate 40 can effectively dehumidify the hot and humid air, thus ensuring the dehumidification efficiency of the product and enabling the rapid drying of clothing.

[0078] In one embodiment of this application, a plurality of through holes are provided on the condenser plate in the extending direction of the drying air duct.

[0079] On the one hand, the presence of through-holes increases the surface area of ​​the condenser plate, thus increasing the contact area between the condenser plate and the humid air. This means that more heat can be transferred from the humid air to the condenser plate in the same amount of time, thereby improving the efficiency of heat exchange, promoting the condensation of moisture in the humid air, and further enhancing the drying effect. On the other hand, the humid air forms convection as it passes through the through-holes. This convection breaks down the boundary layer on the surface of the condenser plate, reducing thermal resistance. Compared with simple surface heat exchange, convective heat exchange is more intense, significantly enhancing the heat transfer effect, improving the performance of the condenser plate, and thus effectively improving the heat exchange efficiency to ensure that the condenser plate fully dehumidifies the humid air.

[0080] In one embodiment of this application, the drying duct includes: a duct shell and a condenser plate.

[0081] One end of the air duct shell is connected to the air outlet, and the other end of the air duct shell is connected to the clothing processing chamber. The air duct shell has an opening.

[0082] The condenser plate is detachably mounted at the opening and seals the opening.

[0083] The aforementioned structure, on the one hand, integrates the condenser tray as part of the drying duct, reducing the space required for a separate condenser tray and thus decreasing the overall size and volume of the duct. This results in the entire drying system occupying less space within the product, improving space utilization. On the other hand, integrating the condenser tray with the drying duct makes the entire drying system more compact. The condenser tray can be combined with the duct's outer shell or other structural components, reducing additional installation space and connecting parts, thereby lowering system complexity and cost.

[0084] like Figure 12 and Figure 13As shown, in one embodiment of this application, at least one of the two heat-conducting plates 41 is provided with a groove, and the groove and the plate surface of the other heat-conducting plate 41 form a thermal superconducting channel 43. Specifically, when one of the two heat-conducting plates 41 is provided with a groove, the groove on one heat-conducting plate 41 and the plate surface of the other heat-conducting plate 41 form a thermal superconducting channel 43; when both heat-conducting plates 41 are provided with grooves, the grooves on the two heat-conducting plates 41 form a thermal superconducting channel 43 (the groove wall is the plate surface of the heat-conducting plate 41). In a specific embodiment of this application, the thermal superconducting channel 43 is formed by a blow-blowing process (the condensing plate 40 can be double-sided blow-blown or single-sided blow-blown). The thermal superconducting channel 43 formed by the blow-blowing process forms a protrusion corresponding to the thermal superconducting channel 43 on the outer surface of the heat-conducting plate 41, and a corresponding groove is formed on the inner surface of the heat-conducting plate 41.

[0085] The above structure creates protrusions on the outer surface of one or two heat-conducting plates 41. These protrusions increase the contact area between the hot and humid air and the condenser plate 40, thereby effectively improving the heat exchange efficiency and ensuring that the condenser plate 40 fully dehumidifies the hot and humid air.

[0086] like Figure 14 As shown, in one embodiment of this application, the washer-dryer combo also includes: a spray pipe 80 (the spray pipe 80 is a component of the cooling device, and other components of the cooling device will not be listed here).

[0087] The spray pipe 80 is inserted into the drying air duct 50 and positioned towards the condenser plate 40. The spray pipe 80 is configured to deliver coolant to the condenser plate 40. In one specific embodiment of this application, the coolant is tap water, and the spray pipe 80 is connected to a water tap via an inlet pipe.

[0088] The condenser plate 40 is cooled by liquid cooling. Since the liquid has a large specific heat capacity, it can quickly cool down the condenser plate 40, thereby improving the heat exchange efficiency between the condenser plate 40 and the humid air in the condenser chamber 51. At the same time, the coolant can also directly exchange heat with the humid air in the condenser chamber 51 to condense and dehumidify the humid air, thereby improving the condensation efficiency and drying efficiency.

[0089] like Figure 2 and 15 As shown, in one embodiment of this application, the drying duct 50 includes a condensation chamber 51 and a heating chamber 52.

[0090] A condenser plate 40 is disposed inside a condenser cavity 51, and a turbulence structure 70 is disposed inside the condenser cavity 51. The turbulence structure 70 is configured to change the flow direction of the hot and humid air.

[0091] The turbulence structure 70 can generate turbulence in the humid and hot air in the drying air duct 50. That is, the turbulence structure 70 makes the air flow path in the condensation chamber 51 more tortuous and complex, increasing the contact frequency between the humid and hot air and the condensation plate 40. This helps more moisture in the humid and hot air to condense into water droplets on the condensation plate 40, thereby effectively improving the heat exchange efficiency and ensuring that the condensation plate 40 fully dehumidifies the humid and hot air.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
