[0002] The washing and drying integrated device has both washing and drying functions, and includes a box body, an outer cylinder, an inner cylinder, an air duct, a fan, a heating component and a condenser. The outer cylinder, the outer shell, the condenser, the air duct and the outer cylinder are connected in sequence. The fan and the heating component are arranged in the air duct. The condenser can dehumidify the air, and the heating component can heat the dehumidified air. During the drying process, lint is generated by the friction between the clothes and the inner cylinder of the washing and drying integrated device, and the lint gradually accumulates on the air duct and the components arranged in the air duct, resulting in a reduction in drying efficiency.

[0003] To remove the lint generated during the drying process, a commonly used lint removal method is to wash the drying air duct, condenser and fan with a large amount of water to remove the lint. However, this method uses a large amount of water to remove the lint, increasing the cost for users to use the washing and drying integrated device, and also causing waste of water resources.

[0004] Therefore, a new control method for a washing and drying integrated device is needed in the art to solve the above problems. Summary of the Invention

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] Based on the problem of wastewater in the existing lint removal method of the existing washing and drying integrated equipment pointed out in the background technology, the present invention provides a control method for a washing and drying integrated equipment, aiming to enable the washing and drying integrated equipment to collect lint, avoid lint accumulation, and this method does not require a large amount of water to be specially supplied for removing lint, thus avoiding waste of water resources.

[0033] Specifically, as Figure 1 shown, the washing and drying integrated equipment of the present invention includes a box body, an outer cylinder 1, an inner cylinder, an air duct 2, a fan 3, a heating member, a condenser 4, a water supply device, and a lint filtering device 5 (the box body, the heating member, and the water supply device are not shown in the figure). The lint filtering device 5 includes a housing 51 and a lint collecting ball 52. The outer cylinder 1, the housing 51, the condenser 4, and the air duct 2 are connected end to end in sequence ( Figure 1 only a partial structure of the outer cylinder 1 is shown in the figure, and the part where the outer cylinder 1 is connected to the air duct 2 is not shown). The fan 3 and the heating member are arranged in the air duct 2. The condenser 4 can dehumidify the air, and the heating member can heat the dehumidified air, that is, the heating member is located on the downstream side of the condenser. The lint collecting ball 52 is located on the downstream side of the opening of the housing 51 communicating with the outer cylinder 1.

[0034] The above heating member can adopt an electric heating metal rod, a PTC electric heater, etc. Those skilled in the art can flexibly set the specific structure of the heating member in actual applications as long as the air can be heated through the heating member.

[0035] Those skilled in the art can flexibly set the specific structure of the water supply device in actual applications, as long as cold water can be supplied to the condenser 4 through the water supply device. For example, the water supply device includes a water supply pipe and a valve provided on the water supply pipe. One end of the water supply pipe is communicated with the water inlet pipe of the washing and drying integrated device, and the other end of the water supply pipe is communicated with the condenser 4. When supplying water to the condenser 4, the valve is opened to allow the water in the water inlet pipe to enter the water supply pipe and then flow into the condenser 4. The water supply device can also be a combination of a water tank and a valve. The water tank is communicated with the condenser 4, and the valve is provided between the water tank and the condenser 4. When supplying water to the condenser 4, the valve is opened to allow the water in the water tank to flow into the condenser 4. In short, the water supply device can supply cold water to the condenser 4. The condenser 4 is specifically a housing structure. When supplying water to the condenser 4, the water will flow through the inner side wall of the condenser 4. At this time, the water vapor in the air flowing through the condenser 4 will condense when it encounters the cold water and flow out together with the cold water, realizing the dehumidification of the air.

[0036] The washing and drying integrated device of the present invention can collect lint by setting the lint collection ball 52, avoiding the accumulation of lint, and this method does not require a large amount of water to be specially supplied for removing lint, thus avoiding waste of water resources.

[0037] The present invention also provides a control method for a washing and drying integrated device, as Figure 3 shown. The control method of the washing and drying integrated device includes: S1. During the process of the washing and drying integrated device executing the drying or air washing program, the fan 3 is operated at a first speed and the water supply device supplies water to the condenser 4, so that the lint collection ball 52 can be wetted in the condenser 4 to collect lint; S2. The fan 3 is operated at a second speed and the water supply device supplies water to the condenser 4, so that water accumulates at the bottom of the housing 51 and the lint collection ball 52 can be impacted by the water to clean the lint on the lint collection ball 52.

[0038] First of all, it should be noted that step S2 can be executed during the process of the washing and drying integrated device executing the drying or air washing program, or can be executed after the washing and drying integrated device executes the drying or air washing program, or can also be executed during the process of the washing and drying integrated device executing programs such as washing and rinsing. Those skilled in the art can reasonably set when to execute step S2, as long as step S2 can be executed at that time to clean the lint on the lint collection ball 52.

[0039] For example: The water supply device includes a water supply pipe and a valve provided on the water supply pipe. One end of the water supply pipe is connected to the water inlet pipe of the washing and drying integrated device, and the other end of the water supply pipe is connected to the condenser 4. Step S1 specifically includes: During the drying program execution of the washing and drying integrated device, the fan 3 operates at a rotational speed of 800 ≤ n (rotational speed of the fan 3) ≤ 1000 rpm, and the valve on the water supply pipe is opened to control the water flow rate to be less than or equal to 0.5 L / min. At this time, water will flow through the inner wall of the condenser 4. The lint collection ball 52 bounces up and down under the action of the fan 3. During the up and down bouncing process, the lint collection ball 52 can be blown by the air into the condenser 4 and be wetted by the water flowing through the condenser 4. When the air flows through, the lint mixed in the air will adhere to the wetted lint collection ball 52 to achieve lint collection. Step S2 specifically includes: During the washing program execution of the washing and drying integrated device, the fan 3 operates at a rotational speed of 1200 ≤ n (rotational speed of the fan 3) ≤ 1500 rpm and the valve on the water supply pipe is opened to control the water flow rate to be greater than or equal to 3 L / min. At this time, water will flow through the inner wall of the condenser 4 and accumulate at the bottom of the housing 51 of the lint filtering device 5 under the action of the fan 3. The lint collection ball 52 bounces up and down under the action of the fan 3. During the up and down bouncing process, the lint collection ball 52 continuously beats on the water accumulated at the bottom of the housing 51 of the lint filtering device 5. The lint adhering to the lint collection ball 52 is impacted by the water and thus detaches from the lint collection ball 52 to achieve cleaning the lint on the lint collection ball 52.

[0040] The above is only an exemplary illustration of Step S1 and Step S2, and does not constitute any limitation to the protection scope. For example: The above describes what rotational speed ranges are respectively adopted for the fan in Step S1 and Step S2, and also describes the water flow rate range for supplying water to the condenser. However, in fact, those skilled in the art can flexibly set the rotational speed of the fan and the water flow rate range for supplying water to the condenser in practical applications, as long as when Step S1 is executed, the settings of the rotational speed of the fan and the magnitude of the water flow rate can achieve the purpose of Step S1, and when Step S2 is executed, the settings of the rotational speed of the fan and the magnitude of the water flow rate can achieve the purpose of Step S2.

[0041] Preferably, the outer cylinder 1 is communicated with the drain pipe of the washing and drying integrated device, and a drain valve is arranged on the drain pipe. After step S2, the control method further includes: S3. Stopping the operation of the blower 3 and opening the drain valve to discharge the water mixed with lint from the outer cylinder 1. Further, the control method further includes: S4. Making the water supply device supply water to the condenser 4 to further clean the lint collecting ball 52. Still taking the water supply device including a water supply pipe and a valve arranged on the water supply pipe as an example, step S4 specifically includes: opening the valve on the water supply pipe and controlling the water flow rate to be greater than or equal to 3 L / min. The water will flow through the inner side wall of the condenser 4. Since the blower 3 stops operating at this time, the lint collecting ball 52 is located at the bottom of the housing 51 of the lint filtering device 5. After the water flows through the condenser 4, it enters the housing 51 of the lint filtering device 5 to wash the lint collecting ball 52 to further clean the lint collecting ball 52.

[0042] Preferably, as Figure 1 shown, the lint filtering device 5 further includes a first grille 53. The first grille 53 is arranged in the opening of the housing 51 communicated with the outer cylinder 1. The lint collecting ball 52 is located on the side of the first grille 53 away from the outer cylinder 1. The first grille 53 can block the lint collecting ball 52 to prevent the lint collecting ball 52 from entering the outer cylinder 1 from the connection part between the housing 51 and the outer cylinder 1, thereby preventing the lint collecting ball 52 from flowing out with the water when discharging the water in the outer cylinder 1.

[0043] In the preferred case where the above-mentioned lint device further includes the first grille 53, the control method further includes: when the washing and drying integrated device executes the washing program, the water level in the outer cylinder 1 is not lower than the top of the grille. When the air mixed with lint flows through the grille, the lint may adhere to the grille. When the washing program is executed, the rotation of the inner cylinder causes the water in the outer cylinder 1 to agitate, constantly beating and flushing the grille to clean the lint adhering to the grille. And setting the water level in the outer cylinder 1 to be not lower than the top of the grille, that is to say, the water in the outer cylinder 1 completely covers the grille. Such a setting can ensure that the water in the outer cylinder 1 can clean every part of the grille, and the cleaning effect is better.

[0044] In a more preferred case, the opening is a circular opening. The first grille 53 includes an annular bracket and a plurality of grid bars arranged on the annular bracket. Each grid bar is arranged vertically, and the annular bracket is adapted to the opening. Among them, the annular bracket is adapted to the opening, that is to say, the diameter length of the annular bracket is set to just enable the annular bracket to be placed in the opening, and the annular bracket and the opening are in contact with each other, and the friction force between the two can make the annular bracket be fixed in the opening. In an alternative case, the lint collecting ball 52 is connected to the housing 51 through a connecting rope, and the connecting rope can limit the movement range of the lint collecting ball 52 to prevent the lint collecting ball 52 from flowing out with the water when discharging the water in the outer cylinder 1.

[0045] In a more preferred case, a second grille is provided between the air duct 2 and the outer cylinder 1. Providing the second grille can block the lint collection ball 52 and prevent the lint collection ball 52 from entering the outer cylinder 1 from the connection between the outer cylinder 1 and the air duct 2, thereby preventing the lint collection ball 52 from flowing out with the water when discharging the water in the outer cylinder 1; furthermore, by providing both the first grille 53 and the second grille, the lint collection ball 52 can be completely prevented from entering the outer cylinder 1, thereby preventing the lint collection ball 52 from flowing out with the water when discharging the water in the outer cylinder 1.

[0046] Preferably, as Figure 2 shown, the lint collection ball 52 includes a sphere 521 and a plurality of protrusions 522 provided on the surface of the sphere 521. By providing the plurality of protrusions 522, the contact area between the lint collection ball 52 and the air can be increased, which is beneficial to lint collection. In a more preferred case, the lengths of the plurality of protrusions 522 are different, and at least some of the protrusions 522 can extend into the gaps of the first grille 53 to clean the first grille 53. The lengths of the plurality of protrusions 522 being different means that not all of the protrusions 522 have the same length. For example, the lengths of each of the protrusions 522 can be different from each other, or some of the protrusions 522 can have the same length while the remaining protrusions 522 have different lengths, and so on. Additionally, in terms of structure, the lint collection ball 52 can also be provided to only include the sphere 521. In terms of material, the lint collection ball 52 can be made of plastic, rubber, etc. Those skilled in the art can flexibly set the specific structure and material of the lint collection ball 52 in actual applications as long as the lint collection ball 52 can collect lint.

[0047] Preferably, as Figure 1 shown, the housing 51 is provided directly below the condenser 4, and the shape of the part of the bottom of the housing 51 facing the condenser 4 is arc-shaped. When the lint collection ball 52 enters the condenser 4 under the action of the fan 3, the arc-shaped part of the condenser 4 can assist the lint collection ball 52 to move smoothly upward into the condenser 4, avoiding a large resistance when the lint collection ball 52 enters the condenser 4.

[0048] Preferably, as Figure 1 shown, the housing 51 is connected to the rear wall of the outer cylinder 1 and is provided at the rear side of the rear wall. A driving device (such as a motor, etc.) for driving the inner cylinder to rotate is provided between the rear wall of the outer cylinder 1 and the box body. Therefore, there is a certain gap between the rear wall of the outer cylinder 1 and the box body. Setting the housing 51 to be connected to the rear wall of the outer cylinder 1 and provided at the rear side of the rear wall can make full use of the gap between the rear wall of the outer cylinder 1 and the box body, and even avoid increasing the original volume of the washing and drying integrated device due to the setting of the lint filtering device 5.

[0049] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle 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 these changes or substitutions will all fall within the protection scope of the present invention.
