[0002] The drying system of a water-condensing washer-dryer can generally be divided into two major sections, the evaporation section and the condensation section.

[0003] The evaporation plate uses electric heating and a fan to blow dry hot air into the washing machine drum to evaporate the moisture on the clothes. The condensation plate uses a fan to absorb the moisture and heat evaporated in the drum into the condensation duct for condensation.

[0004] Currently, most of the water-cooled washer-dryers on the market are equipped with a condensing air duct. During the drying process, the hot and humid air in the washing machine drum cannot be completely condensed by relying on a single condensing air duct.

[0062] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0063] Current washing machines in the existing art have the problem of long drying times and high moisture content of clothes after drying. In the embodiments of the present invention, by modifying the traditional condensing plate structure, a condensation method with dual external condensing ducts and an internal condensing duct is implemented. Traditionally, there is only one external condensing duct. In this embodiment, two external condensing ducts are formed on the outer wall of the outer drum, and two hot and humid air inlets and one outlet are provided on the bottom wall of the outer drum. This significantly reduces drying time while also ensuring the moisture content of clothes after drying. It also offers certain advantages in terms of water and power consumption efficiency.

[0064] The following is combined with Figure 1-Figure 5 The technical solution of this embodiment is described in detail. The following implementation methods and embodiments can be combined with each other unless there is any conflict.

[0065] Example

[0066] like Figure 1-Figure 3 As shown, this embodiment provides a clothes processing device, including:

[0067] The outer tube 1 has a bottom wall formed with an inner wall surface and an outer wall surface 11 facing each other, and a first air inlet 12, a second air inlet 13, and an air outlet 14 extending through the inner wall surface and the outer wall surface 11. The first air inlet 12 and the second air inlet 13 are located at the lower portion of the bottom wall of the outer tube 1, and the air outlet 14 is located at the upper portion of the bottom wall of the outer tube 1.

[0068] It is worth noting that the “upper part” and “lower part” mentioned in the embodiment of the present invention are in a relative relationship.

[0069] The inner cylinder (not shown in the figure) is pivotally arranged in the outer cylinder 1, and the bottom wall of the inner cylinder forms an inner wall surface and an outer wall surface facing each other, and an inner condensation air duct is formed between the outer wall surface of the inner cylinder and the inner wall surface of the outer cylinder 1;

[0070] The outer condensation air duct 2 is provided on the outer wall surface 11 of the outer cylinder 1, and the first air inlet 12, the second air inlet 13 and the air outlet 14 are all connected to the outer condensation air duct 2. The outer condensation air duct 2 includes a first condensation air duct section 21 and a second condensation air duct section 22. The first condensation air duct section 21 extends upward from the first air inlet 12 to the air outlet 14 to adapt to the shape of one radial side of the outer contour of the bottom wall, and the second condensation air duct section 22 extends upward from the second air inlet 13 to the air outlet 14 to adapt to the shape of the other radial side of the outer contour of the bottom wall, wherein the first condensation air duct section 21 and the second condensation air duct section 22 are connected at the air outlet 14; specifically, as Figure 1 and Figure 2 As shown, the first condensation air duct section 21 and the second condensation air duct section 22 are symmetrically arranged arc-shaped air ducts;

[0071] The water inlet device 3 is connected to the first condensation air duct section 21 and the second condensation air duct section 22 and is used to supply water to the first condensation air duct section 21 and the second condensation air duct section 22.

[0072] It should be noted that the water inlet device in the embodiment of the present invention supplies water to the first condensation air duct section 21 and the second condensation air duct section 22, and the water supplied is cooling water.

[0073] It should also be noted that the cooling water mentioned above can be condensed water after condensation, or it can be tap water supplied from a tap water pipe.

[0074] It should also be noted that when the water inlet device supplies water to the first condensation duct 21 and the second condensation duct 22, the water flowing out of the water inlet device can be sprayed onto the inner and outer wall surfaces of the outer cylinder 1, so as to form a water film on the inner and outer wall surfaces 11 of the outer cylinder 1. The water film formed on the inner and outer wall surfaces of the outer cylinder 1 can, on the one hand, increase the heat exchange area between the hot and humid gas and the cooling water, and on the other hand, can save the utilization of water resources. On the other hand, the water film formed on the inner and outer wall surfaces 11 can also collect hair debris in the inner and outer condensation ducts 2, preventing the hair debris from being sucked into the drying fan.

[0075] In the embodiment of the present invention, by changing the structure of the traditional condensation plate, a first condensation duct section 21 and a second condensation duct section 21 are set on the outer wall 11 of the outer cylinder 1 to realize the condensation mode of double external condensation ducts + internal condensation duct. The traditional external condensation duct has only one. In this embodiment, two external condensation ducts are formed on the outer wall 11 of the outer cylinder, and the bottom wall of the outer cylinder is provided with two hot and humid air inlets {a first air inlet 12 and a second air inlet 13} and an air outlet 14. Since the external condensation duct 2 has the first air inlet 12 and the second air inlet, the amount of hot and humid air in the cylinder entering the external condensation duct 2 per unit time will be greatly increased compared with the traditional single-duct condensation, and both external condensation duct sections have condensation water inlet, which will greatly improve the condensation efficiency of the hot and humid air in the cylinder, can greatly reduce the drying time, and at the same time ensure the drying moisture content of the clothes, and also have certain advantages in terms of water and power consumption efficiency.

[0076] Furthermore, in the embodiment of the present invention, by configuring the first condensation air duct section 21 and the second condensation air duct section 22 as curved air ducts from bottom to top, and arranging the air inlet and the air outlet on the upper and lower sides of the air duct sections respectively, the contact area between the condensed water and the humid hot gas can be further increased, thereby further improving the condensation efficiency.

[0077] Further, such as Figure 1 and Figure 2 As shown, the outer condensing air duct 2 includes an outer air duct shell protruding from the outer wall surface 11 of the outer cylinder 1, and the outer air duct shell is formed with an opening adapted to its contour;

[0078] The external condensation air duct 2 further includes an external condensation air duct cover, which is fixed to the opening position of the external air duct housing to seal the external air duct housing;

[0079] The outer air duct shell and the outer cylinder 1 are integrally injection-molded.

[0080] The external condensation air duct 2 in the embodiment of the present invention is integrally injection-molded with the outer cylinder 1 to form an integrated outer cylinder air duct. It is fixed to the external condensation air duct through an external condensation air duct cover to form two external condensation air duct ends. Compared with setting an external condensation air duct separately on the bottom wall of the outer cylinder 1, the production efficiency is higher.

[0081] In any of the above embodiments, Figure 1 and Figure 2 As shown, a bearing mounting portion 15 is provided in the middle of the outer cylinder 1 , and a first condensation air duct section 21 and a second condensation air duct section 22 are respectively provided on both sides of the bearing mounting portion 15 .

[0082] In the embodiment of the present invention, the first condensation air duct section 21 and the second condensation air duct section 22 are symmetrically arranged on both sides of the bearing mounting portion 15, so that the space of the outer wall surface 11 of the outer cylinder 1 can be fully utilized, and the first condensation air duct section 21 and the second condensation air duct section 22 can be prevented from affecting the installation of the bearing of the clothing processing equipment.

[0083] Specifically, such as Figure 2 As shown, the first condensation air duct section 21 includes a first inner air duct wall 211 and a first outer air duct wall 212 opposite to each other, and the first inner air duct wall 211 is arranged closer to the bearing mounting portion 15 relative to the first outer air duct wall 212;

[0084] The second condensing air duct section 22 includes a second inner air duct wall 221 and a second outer air duct wall 222 opposite to each other. The second inner air duct wall 221 is arranged closer to the bearing mounting portion 15 relative to the second outer air duct wall 222.

[0085] The first inner air duct wall 211 and the second inner air duct wall 221 are disposed around the outer periphery of the bearing mounting portion 15 .

[0086] In any of the above embodiments, Figure 1 and Figure 2 As shown, an installation space 4 is formed between the top of the bearing mounting portion 15, the first condensation air duct section 21 and the second condensation air duct section 22, and the water inlet device 3 is disposed in the installation space 4;

[0087] The installation space 4 is provided close to the air outlet 14 relative to the first air inlet 12 , the second air inlet 13 and the air outlet 14 ;

[0088] Relative to the first air inlet 12 and the air outlet 14, the communication position between the water inlet device 4 and the first condensation air duct section 21 is arranged close to the air outlet 14;

[0089] Relative to the second air inlet 13 and the air outlet 14 , the communication position between the water inlet device 3 and the second condensation air duct section 22 is arranged close to the air outlet 14 .

[0090] In the embodiment of the present invention, the water inlet device 4 is arranged in the installation space 4 formed between the top of the bearing mounting portion 15, the first condensation duct section 21 and the second condensation duct section 22, so that the outer wall space of the outer drum 1 can be fully utilized. On the one hand, the overall design size of the clothing processing equipment is reduced. On the other hand, the condensed water entering the outer condensation duct 2 has a sufficient flow path, thereby improving the condensation efficiency while saving water resources.

[0091] Specifically, such as Figure 3 As shown, the water inlet device 3 includes a three-way water pipe, and the three-way water pipe includes a water inlet pipe 31, a first water outlet pipe 32 and a second water outlet pipe 33;

[0092] The first water outlet pipe 32 is in communication with the first condensation air duct section 21 , and the second water outlet pipe 33 is in communication with the second condensation air duct section 22 .

[0093] It is worth noting that, in any of the above embodiments, a plurality of inner guide ribs are provided on the inner wall surface of the outer cylinder 1;

[0094] The clothes processing device further includes an inner condensation water injection pipeline for injecting water into the inner condensation air duct, and the inner guide ribs are used to guide the condensed water injected into the inner condensation air duct;

[0095] The clothing processing device also includes a drying duct 5, which is provided with a drying fan and a heating device. The air inlet of the drying duct 5 is connected to the inner condensation duct and / or the outer condensation duct, and the air outlet of the drying duct 5 is connected to the inner drum.

[0096] Condensed water flows through the internal condensation inlet pipe and lands on the guide ribs on the inner wall of the outer tube 1. Because these ribs are located on the inner wall of the bottom wall of the outer tube 1 and are numerous in number, the condensed water forms a condensation curtain on the guide ribs on the inner wall of the outer tube 1. The condensed water travels a long distance along the guide ribs, increasing its contact time with the hot and humid air. This condensation curtain condenses a portion of the hot and humid air in the tube, forming relatively dry cool air. This air is then blown through the air outlet 14 by the drying fan to the heating device for heating before entering the inner tube, completing the drying cycle.

[0097] In any of the above embodiments, a first air inlet 12 is provided at the first air inlet 12 , a second air inlet 13 is provided at the second air inlet 13 , and an air outlet 141 is provided at the air outlet 14 ;

[0098] The clothes processing device has a drying mode, and the drying mode has a drying and heating stage. The clothes processing device also includes:

[0099] Temperature sensor, the temperature sensor is used to detect the temperature in the inner drum and / or outer drum 1; it is worth noting that the temperature sensor is arranged on the temperature sensing bag on the clothing processing device. The temperature sensor can determine the start and stop of the heating device, and then determine the drying temperature in the inner drum and / or outer drum 1.

[0100] The controller is used to control the opening of the first air inlet valve and / or the opening of the second air inlet valve and / or the opening of the air outlet valve according to the temperature value in the inner drum and / or the temperature value in the outer drum and / or whether the clothing processing device is in the drying and heating stage.

[0101] Specifically, the second aspect of the embodiment of the present invention provides a Figure 4 and Figure 5 The drying control method of the clothes processing device shown is applied to the above clothes processing device, wherein the drying control method includes:

[0102] When the clothes processing device is in the drying mode, obtaining whether the clothes processing device has entered the drying and heating stage;

[0103] If so, controlling the first air inlet valve and the second air inlet valve to close, and controlling the air outlet valve to open at a first opening degree;

[0104] If not, the first air inlet valve, the second air inlet valve and the air outlet valve are controlled to be fully opened;

[0105] When the air outlet valve is opened at the first opening degree, the air outlet is in a half-open state.

[0106] In the embodiment of the present invention, the reason why the air outlet valve is controlled to open at the first opening degree when the clothing processing apparatus enters the drying and heating stage, and the first air inlet valve, the second air inlet valve and the air outlet valve are controlled to be fully opened when the clothing processing apparatus has not entered the drying and heating stage, is to accelerate the temperature increase in the inner drum and / or the outer drum 1.

[0107] Furthermore, after the clothing processing equipment enters the drying and heating stage, the temperature value in the inner drum and / or the temperature value in the outer drum is obtained, and the opening of the first air inlet valve and / or the opening of the second air inlet valve and / or the opening of the air outlet valve are adjusted according to the temperature value in the inner drum and / or the temperature value in the outer drum.

[0108] In the embodiment of the present invention, the reason why the opening of the first air inlet valve and / or the opening of the second air inlet valve and / or the opening of the air outlet valve are adjusted according to the temperature value in the inner drum and / or the temperature value in the outer drum after the clothing processing device enters the drying and heating stage is to shorten the drying time and the drying efficiency of the clothes.

[0109] Specifically, adjusting the opening of the first air inlet valve and / or the opening of the second air inlet valve and / or the opening of the air outlet valve according to the temperature value in the inner tube and / or the temperature value in the outer tube includes:

[0110] If the temperature value in the inner tube is greater than the first preset temperature value and / or the temperature value in the outer tube is greater than the first preset temperature value, the first air inlet valve, the second air inlet valve and the air outlet valve are controlled to be fully opened.

[0111] More specifically, the drying control method further includes:

[0112] When the temperature value in the inner tube is greater than the first preset temperature value and / or the temperature value in the outer tube is greater than the first preset temperature value, determining whether the temperature value in the inner tube is greater than the second preset temperature value and / or the temperature value in the outer tube is greater than the second preset temperature value;

[0113] If the temperature value in the inner tube is greater than the second preset temperature value and / or the temperature value in the outer tube is greater than the second preset temperature value, the first air inlet valve, the second air inlet valve and the air outlet valve are controlled to be fully opened, and the electric heating device is turned off;

[0114] If the temperature value in the inner tube is less than or equal to the second preset temperature value and / or the temperature value in the outer tube is less than or equal to the second preset temperature value, adjusting the opening of the first air inlet valve and / or adjusting the opening of the second air inlet valve and / or adjusting the opening of the air outlet valve according to the difference between the second preset temperature value and the temperature value in the inner tube and / or according to the difference between the second preset temperature value and the temperature value in the outer tube;

[0115] The second preset temperature value is greater than the first preset temperature value.

[0116] More specifically, adjusting the opening of the first air inlet valve and / or adjusting the opening of the second air inlet valve and / or adjusting the opening of the air outlet valve according to the difference between the second preset temperature value and the temperature value in the inner tube and / or according to the difference between the second preset temperature value and the temperature value in the outer tube includes:

[0117] If the difference between the second preset temperature value and the temperature value in the inner tube is less than the preset difference and / or the difference between the second preset temperature value and the temperature in the outer tube is less than the preset difference, controlling the first air inlet valve, the second air inlet valve and the air outlet valve to maintain the current opening;

[0118] If the difference between the second preset temperature value and the temperature value in the inner tube is greater than or equal to the preset difference and / or the difference between the second preset temperature value and the temperature in the outer tube is greater than or equal to the preset difference, the first air inlet valve and the second air inlet valve are controlled to open at a first opening degree, and the air outlet valve is controlled to be fully opened;

[0119] When the first air intake valve is opened at the first opening degree, the first air intake port is in a half-open state; when the second air intake valve is opened at the first opening degree, the second air intake port is in a half-open state.

[0120] Preferably, the preset difference mentioned above is set to 2°C.

[0121] In order to more clearly understand the working principle of the clothes processing device in the embodiment of the present invention, the following Figure 1-Figure 5 To explain in detail:

[0122] like Figure 1 、 Figure 2As shown, a new duct condensation method is proposed in the embodiment of the present invention, which utilizes the integrated structure of the external condensation duct and the outer drum, and sets two condensation duct areas on the outer drum 1. The hot and humid air in the washing machine is drawn into the condensation duct through the drying fan, and the hot and humid air is condensed through the two condensation ducts. Since the two condensation ducts respectively have a first air inlet and a second air inlet, the air flow rate when the hot and humid air in the outer drum 1 and the inner drum enters the external condensation duct 2 will be greatly increased per unit time compared with the traditional single-duct condensation. Since the outer condensation duct 2 has two condensation areas {a first condensation duct section 21 and a second condensation duct section 22}, and both condensation areas have condensation water inlets, the condensation efficiency of the hot and humid air in the inner drum and / or outer drum 1 will be greatly improved.

[0123] like Figure 1 and Figure 2 As shown, condensed water flows through the inner condensation inlet pipe and falls onto the guide ribs. Because the guide ribs are located on the inner wall surface of the bottom wall of the outer drum 1 and are numerous, the condensed water forms a condensation curtain on the guide ribs. The condensed water flows along the guide ribs for a longer distance, which increases its contact time with the hot and humid air. This condensation curtain condenses a portion of the hot and humid air in the drum, forming relatively dry cool air. This air is then blown through the air outlet 14 by the drying fan to the heating device for heating before entering the inner drum, completing the drying cycle.

[0124] like Figure 3 As shown, the water inlet device for injecting water into the external condensation duct 2 is a three-way water pipe, which can transport the condensed water to the first condensation duct section 21 and the second condensation duct section 22 respectively, thereby improving the condensation heat exchange efficiency of the humid and hot air in the external condensation duct 2.

[0125] like Figure 2 As shown, the first air inlet 12, the second air inlet 13 and the air outlet 14 can all be controlled by the solenoid valve to realize the three states of "fully open", "half open" and "closed". When entering the drying mode, it is determined whether the drying logic enters the "drying and heating" stage. If not, all the air inlets and outlets are kept open; if so, the first air inlet 12 and the second air inlet 13 are closed first, and the air outlet 14 is half open, in order to speed up the temperature increase in the barrel.

[0126] When the temperature T inside the drum exceeds the first preset temperature value T1, the drying process begins. The air inlet and outlet are fully open, and the temperature T is checked to see if it exceeds the second preset temperature value T2. If so, the air inlet and outlet remain fully open and the heating device is turned off. If not, a check is performed to see if T2-T is less than 2°C. If not, the first and second air inlets 12 and 13 remain half-open, and the air outlet 14 is fully opened. If so, the current state remains unchanged.
