[0088] Background Introduction

[0089] Most multi-drum washing machines on the market are still manually operated. This is extremely inconvenient when users are carrying clothes or other items. Furthermore, there is a risk of burns from high-temperature gases when the drum is too hot.

[0090] Based on this, such as Figures 1-7 As shown, the first aspect of this application provides a door opening control method for a fabric processing device. The fabric processing device includes multiple fabric processing cylinders, which share the same drying system. The drying system includes a main drying duct and multiple air inlets and multiple air outlets connected to both sides of the main drying duct's inlet and outlet. The air outlets of the multiple air inlets are connected one-to-one with the air inlets of the multiple fabric processing cylinders, and the air inlets of the multiple air outlets are connected one-to-one with the air outlets of the multiple fabric processing cylinders. An air distribution device is provided between the air inlets of the main drying duct and the air outlets of the multiple air outlets and / or between the air outlets of the main drying duct and the air inlets of the multiple air inlets. By controlling the air distribution device, airflow between at least two fabric processing cylinders can be connected. The door opening control method includes:

[0091] When the target fabric processing cylinder is in a high-temperature operating state or has not reached the preset time after the high-temperature operating state, it receives a cylinder door opening signal and obtains the internal temperature information of the target fabric processing cylinder.

[0092] Determine whether the target fabric treatment cylinder meets the opening conditions. The opening conditions must at least meet the requirement that the temperature inside the cylinder is lower than the set value.

[0093] If the target fabric treatment cylinder meets the opening conditions, then open the cylinder door of the target fabric treatment cylinder;

[0094] If the target fabric treatment cylinder does not meet the opening conditions, the status information of the non-target fabric treatment cylinder is obtained, and the status information of the non-target fabric treatment cylinder is used to determine whether the non-target fabric treatment cylinder meets the ventilation and cooling conditions for the target fabric treatment cylinder.

[0095] If the non-target fabric treatment cylinder meets the ventilation and cooling conditions for the target fabric treatment cylinder, the air distribution device is controlled to connect the non-target fabric treatment cylinder and the target fabric treatment cylinder, so that the air in the non-target fabric treatment cylinder flows into the target fabric treatment cylinder to cool it.

[0096] The fabric processing equipment in this embodiment can automatically open the door of the fabric processing cylinder according to the door opening signal, eliminating the need for manual opening. Furthermore, when the target cylinder door receives an opening command, the air distribution device can be controlled accordingly based on the temperature information of the target cylinder and the non-target cylinders. This allows the use of cool airflow from the non-target cylinders to cool the target cylinder when the temperature inside is too high, thus accelerating the temperature drop within the target cylinder. This fully utilizes the airflow from the non-target cylinders to cool the target cylinder, preventing burns from hot airflow when the door is opened directly and shortening the waiting time for the target cylinder door to open.

[0097] Furthermore, in some possible implementations, the control method further includes:

[0098] If the non-target fabric treatment cylinder does not meet the ventilation and cooling conditions for the target fabric treatment cylinder, the air distribution device is controlled to direct the airflow from the target fabric treatment cylinder to the non-target fabric treatment cylinder.

[0099] When the temperature inside the target drum is too high, and the non-target fabric treatment drum is still running a drying or steam treatment program, the high-temperature airflow inside the target fabric treatment drum can be directed to the non-target treatment drum, which is in a drying or steam treatment state, by controlling the air distribution device, so as to shorten the time when the non-target fabric treatment drum is running a drying or steam treatment program.

[0100] It is worth noting that when the fabric treatment drum is in the drying state, the temperature inside the drum is between 60℃ and 90℃, and when the fabric treatment drum is in the steam treatment state, the temperature inside the drum is between 80℃ and 100℃.

[0101] Specifically, in some possible implementations, the air distribution device includes a first air distribution device connected to the air inlet of the main drying air duct and / or a second air distribution device connected to the air outlet of the main drying air duct. The air inlet of the first air distribution device is connected to the air outlet of a plurality of air outlet ducts, and the air inlet of the plurality of air outlet ducts is connected one-to-one with the air outlet of a plurality of fabric processing cylinders. The air outlet of the second air distribution device is connected to the air inlet of a plurality of air inlets, and the air outlet of the plurality of air inlets is connected one-to-one with the air inlet of a plurality of fabric processing cylinders. The first air distribution device can be controlled to selectively connect the air inlet of the main drying air duct to one or more of the plurality of air outlet ducts and to selectively connect the plurality of air outlet ducts. The second air distribution device can be controlled to selectively connect the air outlet of the main drying air duct to one or more of the plurality of air inlets and to selectively connect the plurality of air inlets.

[0102] The control air distribution device connects the non-target fabric treatment cylinder and the target fabric treatment cylinder, so that air from the non-target fabric treatment cylinder flows into the target fabric treatment cylinder to cool it, including:

[0103] Control the second air distribution device to connect the air outlet of the main drying air duct with the air inlet of the target fabric treatment cylinder, and disconnect the air outlet of the main drying air duct from the air inlet of the non-target fabric treatment cylinder; control the first air distribution device to connect the air inlet of the main drying air duct with the air outlet of the target fabric treatment cylinder, and connect the air inlet of the main drying air duct with the air outlet of the non-target fabric treatment cylinder.

[0104] Specifically, in some possible implementations, the air distribution device includes a first air distribution device connected to the air inlet of the main drying air duct and / or a second air distribution device connected to the air outlet of the main drying air duct. The air inlet of the first air distribution device is connected to the air outlet of a plurality of air outlet ducts, and the air inlet of the plurality of air outlet ducts is connected one-to-one with the air outlet of a plurality of fabric processing cylinders. The air outlet of the second air distribution device is connected to the air inlet of a plurality of air inlets, and the air outlet of the plurality of air inlets is connected one-to-one with the air inlet of a plurality of fabric processing cylinders. The first air distribution device can be controlled to selectively connect the air inlet of the main drying air duct to one or more of the plurality of air outlet ducts and to selectively connect the plurality of air outlet ducts. The second air distribution device can be controlled to selectively connect the air outlet of the main drying air duct to one or more of the plurality of air inlets and to selectively connect the plurality of air inlets.

[0105] The air distribution device controls the airflow from the target fabric treatment cylinder to the non-target fabric treatment cylinder, including:

[0106] By controlling the first air distribution device, the air inlet of the main drying air duct is connected to the air outlet of the target fabric treatment cylinder, and the air inlet of the main drying air duct is connected to the air outlet of the non-target fabric treatment cylinder. By controlling the second air distribution device, the air outlet of the main drying air duct is connected to the air inlet of the non-target fabric treatment cylinder, and the air outlet of the main drying air duct is disconnected from the air inlet of the target fabric treatment cylinder.

[0107] Furthermore, in some possible implementations, the door opening control method also includes:

[0108] The opening conditions for the target fabric treatment cylinder must at least meet the requirement that the target fabric treatment cylinder is not in a high-temperature operating state;

[0109] Door opening control methods also include:

[0110] When the target fabric processing cylinder receives a gate opening signal and is in a high-temperature operating state, the target fabric processing cylinder is controlled to stop the high-temperature operating state.

[0111] That is, when the target fabric treatment drum, which is in the drying or steam treatment state, receives an opening signal, it should stop its current drying or steam treatment state.

[0112] Furthermore, in some possible implementations, determining whether the non-target fabric treatment cartridge meets the ventilation and cooling conditions for the target fabric treatment cartridge based on the status information of the non-target fabric treatment cartridge includes:

[0113] When the non-target fabric processing cylinder is in a non-high temperature operating state and the temperature value inside the non-target fabric processing cylinder is lower than the set value, it is determined that the non-target fabric processing cylinder meets the ventilation and cooling conditions for the target fabric processing cylinder.

[0114] If the non-target fabric treatment cylinder is operating at high temperature and / or the temperature inside the non-target fabric treatment cylinder is greater than or equal to the set value, then it is determined that the non-target fabric treatment cylinder does not meet the ventilation and cooling conditions for the target fabric treatment cylinder.

[0115] Furthermore, in some possible implementations, the fabric processing equipment includes multiple sensors, and the sensing signals of the multiple sensors are defined according to preset rules as different target fabric processing cylinder door opening signals.

[0116] Specifically, in some possible implementations, the multiple fabric processing tubes include an upper tube and a lower tube, and the multiple sensors include a first sensor, a second sensor, and a third sensor;

[0117] Control methods also include:

[0118] When the first and second sensors are triggered, a signal to open the upper cylinder door is sent.

The fabric processing device includes multiple fabric processing cylinders that share the same drying system. The drying system includes a main drying duct and multiple air inlets and multiple air outlets connected to both sides of the main drying duct's inlet and outlet. The air outlets of the multiple air inlets are connected one-to-one with the air inlets of the multiple fabric processing cylinders, and the air inlets of the multiple air outlets are connected one-to-one with the air outlets of the multiple fabric processing cylinders. An air distribution device is provided between the air inlets of the main drying duct and the air outlets of the multiple air outlets and / or between the air outlets of the main drying duct and the air inlets of the multiple air inlets. By controlling the air distribution device, airflow between at least two fabric processing cylinders can be connected. The door opening control method includes:

[0125] Door opening control methods include:

[0126] In response to a second sensing signal that the doors of multiple target fabric processing cylinders open simultaneously, the internal temperature information of the multiple target fabric processing cylinders is acquired.

[0127] Determine whether multiple target fabric treatment cylinders meet the door opening conditions. The door opening conditions must at least meet the requirement that the temperature inside the cylinder is lower than a set value.

[0128] If the opening conditions are met for multiple target fabric processing cylinders, then the cylinder doors of multiple target fabric processing cylinders are opened.

[0129] If at least one of the multiple target fabric processing cylinders does not meet the door opening condition, then obtain the status information of whether at least one of the multiple target fabric processing cylinders meets the requirement of ventilating and cooling the target fabric processing cylinder that does not meet the door opening condition.

[0130] If the status information of at least one of the multiple target fabric processing cylinders meets the requirements for ventilation and cooling treatment of the target fabric processing cylinder that does not meet the door opening conditions, then the air distribution device is controlled to direct the air in the target fabric processing cylinder that meets the ventilation and cooling treatment requirements to the target fabric processing cylinder that does not meet the door opening conditions, so as to cool the target fabric processing cylinder that does not meet the door opening conditions.

[0131] When multiple target cylinders receive an opening command simultaneously, if at least one target cylinder does not meet the opening conditions, but at least one target cylinder can cool down the target cylinder that does not meet the opening conditions, the air distribution device can be controlled to allow the target cylinder with a lower internal temperature to cool down the target cylinder with a higher internal temperature. This avoids the risk of the high-temperature airflow burning the user when the door is opened directly, and also shortens the waiting time for the target cylinder to open.

[0132] Specifically, the air distribution device includes a first air distribution device connected to the air inlet of the main drying air duct and / or a second air distribution device connected to the air outlet of the main drying air duct. The air inlet end of the first air distribution device is connected to the air outlet ends of multiple air outlet ducts, and the air inlet ends of the multiple air outlet ducts are connected one-to-one with the air outlets of multiple fabric processing cylinders. The air outlet end of the second air distribution device is connected to the air inlet ends of multiple air inlet ducts, and the air outlet ends of the multiple air inlet ducts are connected one-to-one with the air inlet ends of multiple fabric processing cylinders. The first air distribution device can be controlled to selectively connect the air inlet of the main drying air duct to one or more of the multiple air outlet ducts and to selectively connect the multiple air outlet ducts. The second air distribution device can be controlled to selectively connect the air outlet of the main drying air duct to one or more of the multiple air inlet ducts and to selectively connect the multiple air inlet ducts.

[0133] The air distribution device controls the airflow within the target fabric treatment cylinder that meets the ventilation and cooling requirements to the target fabric treatment cylinder that does not meet the door opening conditions, including:

[0134] By controlling the first air distribution device, the air inlet of the main drying air duct is connected to the air outlet of the target fabric processing tube that does not meet the door opening conditions, and the air inlet of the main drying air duct is connected to the air outlet of the target fabric processing tube that meets the ventilation and cooling treatment requirements. By controlling the second air distribution device, the air outlet of the main drying air duct is connected to the air inlet of the target fabric processing tube that does not meet the door opening conditions, and the air outlet of the main drying air duct is disconnected from the air inlet of the target fabric processing tube that meets the ventilation and cooling requirements.

[0135] Furthermore, in some possible implementations, the fabric treatment equipment also includes a fan assembly located in the main drying duct;

[0136] Control methods also include:

[0137] If none of the target fabric processing cylinders meet the door opening conditions, the air supply volume of the fan assembly is increased to cool the multiple target fabric processing cylinders by increasing the air volume entering the multiple target fabric processing cylinders.

[0138] Furthermore, in some possible implementations, the opening conditions of the target fabric treatment tube also need to meet the following conditions: the target fabric treatment tube is not in a high-temperature operating state or the target fabric treatment tube has ended the high-temperature operating state for more than a preset time.

[0139] Door opening control methods also include:

[0140] If the target fabric treatment cylinder is operating at high temperature, control the target fabric treatment cylinder to stop operating at high temperature.

[0141] Specifically, in some possible implementations, obtaining the status information of whether at least one of the multiple target fabric processing cylinders meets the requirement of ventilating and cooling a target fabric processing cylinder that does not meet the opening conditions includes:

[0142] Determine if a target fabric treatment cylinder exists that is not in a high-temperature operating state and whose internal temperature is lower than the set value.

[0143] If present, the target fabric treatment cylinder is determined to meet the requirements for ventilated cooling treatment of other target fabric treatment cylinders.

[0144] Furthermore, in some possible embodiments, the multiple fabric processing cylinders include an upper cylinder and a lower cylinder, and the fabric processing equipment also includes a first sensor, a second sensor and a third sensor, which are all located at the bottom of the lower cylinder and distributed laterally along the lower cylinder.

[0145] Control methods also include:

[0146] When the first, second, and third sensors are triggered in sequence, a signal is sent to simultaneously open both cylinder doors.

[0147] As can be seen from the first and second aspects of the above embodiments, in this application embodiment, by setting multiple fabric processing tubes in the fabric processing equipment and setting multiple sensors on the fabric processing equipment, when it is necessary to open one or more tubes of the fabric processing equipment, the triggering conditions of multiple sensors can be changed to make the fabric processing equipment automatically open the corresponding tube door. At the same time, when opening the corresponding tube door, by acquiring the status information of the target fabric processing tube and combining the status information to selectively control the communication status between multiple tubes and / or the operating parameters of multiple tubes, the fabric processing equipment can automatically open the tube door at the most appropriate time, avoiding the risk of accidents caused by incorrect opening timing of the tube door.

[0148] Specifically, in some possible implementations, the triggering of multiple sensors includes the location of the triggered sensors and / or the number of triggered sensors and / or the triggering order of the triggered sensors.

[0149] In this embodiment of the application, when sensors at different locations and / or different numbers of sensors and / or multiple sensors are triggered in different triggering sequences, the sensing device can send out different sensing signals, and the controller can determine the target fabric processing tube that needs to be opened based on the different sensing signals.

[0150] In some specific implementations, taking a twin-tub washing machine as an example, the fabric processing equipment is:

[0151] When the system detects a user's intention to open the door of a single cylinder, it determines whether the cylinder meets the opening conditions. If it does, the door is opened; otherwise, the display shows the reason why the door cannot be opened and the waiting time. Specifically, if the cylinder is drying and has exceeded the opening temperature, it checks whether another cylinder is drying. If so, the air distribution device directs all the hot air to the other cylinder, and the target cylinder waits for its temperature to drop to meet the opening conditions before opening. If the other cylinder is not drying and its temperature is low, the heat exchange module stops heating, and the air distribution device directs the cool air from the other cylinder to the target cylinder to achieve rapid cooling.

[0152] When the system detects a user's intention to open the doors of both drums, it determines whether the conditions for opening the doors are met. If the conditions are not met, the display screen will show the reason why the doors cannot be opened and the waiting time. Specifically, if a single drum is drying, upon receiving the door opening command, the heat exchange components will stop heating, and the air distribution device will direct cool air to that drum to lower its temperature. Once the temperature drops to a safe level, the door lock will unlock and the door will open. If both drums are drying, upon receiving the double-drum door opening command, the heat exchange components will stop heating, and the fan components will increase the airflow to quickly cool both drums. Once the temperature drops to a safe level, the double-drum door lock will unlock and the door will open.

[0153] As can be seen from the above control logic in this embodiment, the automatic opening operation of the fabric processing equipment can be realized, and the fabric processing equipment can be opened under the most appropriate circumstances to avoid the risk of accidents caused by incorrect timing of the opening of the tube door.

[0154] It should be noted that in this embodiment, the sensing device will only emit corresponding sensing signals if multiple sensors are triggered in a specific order, thereby preventing accidental door opening. Preferably, all of the aforementioned sensors are infrared sensors.

[0155] In some specific implementations, automatic door opening can be achieved through the user's leg sweeping motion. Specifically, different leg sweeping motions correspond to different infrared sensors. When determining whether a single drum is opening, the user can set the middle infrared sensor in combination with one of the two side sensors as the opening condition. That is, during a short-stroke leg sweeping motion, blocking the middle sensor combined with one of the two side sensors allows a single door to open. When both drums need to open simultaneously, the user can perform a long-stroke leg sweeping motion, blocking all three sensors, which the system then determines as both drums opening simultaneously. This multi-drum washing machine shares an air duct with a single heating module. An air distribution device is installed in the air duct to direct airflow to each drum. When the user determines whether to open a single or double drum through the leg sweeping motion, it checks whether the drum exceeds the set opening temperature. If so, the heating module is paused. If the other drum is not drying, the air distribution device directs cool air to the overheated drum to lower its temperature.

[0156] Furthermore, a third aspect of the present application provides a fabric processing device that employs the door opening control method provided in the first aspect of the present application and / or the door opening control method provided in the second aspect of the present application.

[0157] To better understand how the air distribution device in fabric processing equipment directs airflow from one cylinder to another, the following section will combine... Figures 4-7 Please provide a detailed explanation:

[0158] First, let’s introduce the fabric processing equipment. Taking a twin-tub washing machine with an upper tub 1 and a lower tub 2 as an example, the upper tub 1 includes a first outer tub and a first inner tub that can be pivotally disposed in the first outer tub. The lower tub 2 includes a second outer tub and a second inner tub that can be pivotally disposed in the second outer tub.

[0159] An air distribution device is used, with the upper cylinder 1 and lower cylinder 2 connected by the air distribution device. The upper cylinder 1 and the air distribution device form a first circulating air duct, and the lower cylinder 1 and the air distribution device form a second circulating air duct. Specifically, the first and second circulating air ducts share a main drying air duct. The air distribution device includes a first air distribution device connected to the air inlet of the main drying air duct and a second air distribution device connected to the air outlet of the main drying air duct. The air inlet of the first air distribution device is connected to the air outlet of multiple air outlets, and the air inlet of the multiple air outlets is connected to multiple fabric treatments. The air outlets of the drying drums are connected one-to-one. The air outlet of the second air distribution device is connected to the air inlet of multiple air inlets. The air outlets of the multiple air inlets are connected one-to-one with the air inlets of multiple fabric processing drums. The first air distribution device can be controlled to selectively connect the air inlet of the main drying air duct with one or more of the multiple air outlets and to selectively connect the multiple air outlets. The second air distribution device can be controlled to selectively connect the air outlet of the main drying air duct with one or more of the multiple air inlets and to selectively connect the multiple air inlets.

[0160] The vibration damping system includes a first vibration damping system located in the upper cylinder 1 and a second vibration damping system located in the lower cylinder 2 (not shown in the figure). Both the first and second vibration damping systems can be a combination of a spring and a damper.

[0161] In this embodiment of the invention, two sets of air distribution devices are provided between the upper drum 1 and the lower drum 2. On the one hand, these two sets of air distribution devices allow the upper drum 1 and the lower drum 2 to share a single air duct, eliminating the need for additional air ducts and reducing the size and manufacturing cost of the washing machine. On the other hand, the two sets of air distribution devices also connect the upper drum 1 and the lower drum 2, improving the rigidity of the twin drums during operation. During twin drum operation, the vibrations of the twin drums can be transmitted between them through the air distribution devices, and the vibrations are ultimately eliminated by the vibration damping systems of the two drums. Each drum has a vibration damping system consisting of a spring and a damper. That is, the two drums connected by a shared air duct can transmit vibrations to the vibration damping systems of both drums during operation, enhancing the stability and reliability of twin drum operation. Furthermore, when the upper drum and / or the lower drum needs to be opened, the two sets of air distribution devices can mix the airflow in the two drums in different ways to quickly reduce the temperature inside the target drum.

[0162] Specifically, the air distribution device 4 is connected to the upper cylinder 1 by a fixed connection and a flexible connection, and the air distribution device is connected to the lower cylinder 2 by a fixed connection and a flexible connection.

[0163] More specifically, the first air distribution device is located at the front of the fabric processing equipment and is connected to the front air duct assembly; the second air distribution device is located at the rear of the fabric processing equipment and is connected to the rear air duct assembly.

[0164] The front air duct assembly includes two air inlets connected to two air outlets of the first air distribution device. Specifically, the two air inlets include a first front air duct 3 and a second front air duct 53. One end of the first front air duct 3 is connected to one air outlet of the first air distribution device and the other end is connected to the front side of the upper cylinder 1. One end of the second front air duct 53 is connected to the other air outlet of the first air distribution device and the other end is connected to the front side of the lower cylinder 2.

[0165] The rear air duct assembly includes a first rear air duct 6 and a second rear air duct 10 connected to two air inlets of the second air distribution device. One end of the first rear air duct 6 is connected to one air inlet of the second air distribution device and the other end is connected to the rear side of the upper cylinder 1. One end of the second rear air duct 10 is connected to the other air inlet of the second air distribution device and the other end is connected to the rear side of the lower cylinder 2.

[0166] The main drying air duct, the first front air duct 3, the upper cylinder 1 and the first rear air duct 6 are connected in sequence to form the circulating drying air path of the upper cylinder 1. The main drying air duct, the second front air duct 53, the lower cylinder 2 and the second rear air duct 10 are connected in sequence to form the circulating drying air path of the lower cylinder 2.

[0167] The first front air duct 3 is connected to the front side of the upper cylinder 1 in a first connection method, the second front air duct 53 is connected to the front side of the lower cylinder 2 in a second connection method, the first rear air duct 6 is connected to the rear side of the upper cylinder 1 in a second connection method, and the second rear air duct 10 is connected to the rear side of the lower cylinder 2 in a first connection method.

[0168] The first connection method is one of a fixed connection method and a soft connection method, and the second connection method is the other of a fixed connection method and a soft connection method.

[0169] Specifically, the first front air duct 3 is fixedly connected to the upper cylinder 1 and flexibly connected to the middle air duct, and the second front air duct 53 is flexibly connected to the lower cylinder 2 and flexibly connected to the middle air duct.

[0170] The first front air duct 3, the first air distribution device, and the second front air duct 53 are connected sequentially from top to bottom;

[0171] Among them, such as Figures 4-6 As shown, the connection between the outlet of the first front air duct 3 and the upper cylinder 1 is located at the top of the door seal of the upper cylinder 1; the connection between the outlet of the second front air duct 53 and the lower cylinder 2 is located at the top of the door seal of the lower cylinder 2.

[0172] It is worth noting that when the upper cylinder 1 and the lower cylinder 2 are distributed vertically in the embodiments of the present invention, the upper cylinder 1, which is located at the top, is at a higher position and is lighter in weight, making it prone to swaying. Therefore, by setting the first front air duct 3, which is fixedly assembled with the upper cylinder 1, the upper cylinder 1 can be counterweighted, thereby improving the overall operational stability of the machine.

[0173] Meanwhile, since the first front air duct 3 is fixedly mounted on the upper cylinder 1, when the upper cylinder 1 shakes, it can prevent the first front air duct 3 from colliding with the upper cylinder 1. {Since the first front air duct 3 is fixedly mounted on the upper cylinder 1, when the upper cylinder 1 moves, the first front air duct 3 moves synchronously, thereby avoiding collision}.

[0174] Preferably, the first front air duct 3 is fixed to the surface of the upper cylinder 1 by screws.

[0175] Specifically, the first rear air duct 6 is flexibly connected to the upper cylinder 1 and to the second air distribution device, and the second rear air duct 10 is fixedly connected to the lower cylinder 2 and to the second air distribution device.

[0176] The first rear air duct 6, the second air distribution device, and the second rear air duct 10 are connected sequentially from top to bottom.

[0177] It should be noted that when the air duct component in the embodiment of the present invention adopts a flexible connection method, it uses a flexible connector 52. Preferably, the flexible connector 52 includes a flexible connector head and a clamp. By setting the flexible connector head and the clamp, the sealing effect at the flexible connection position can be improved.

[0178] It should also be noted that the material of the flexible connector 52 used in the embodiments of the present invention only needs to meet the requirement of having a certain supporting effect when receiving a small impact force and having a certain elastic deformation effect when receiving a large impact force. The specific material of the flexible connector is not limited in the embodiments of the present invention.

[0179] In this embodiment of the invention, a flexible connector is used to connect the air duct. This ensures the transmission of vibration force while preventing damage to the connection point caused by excessive vibration force.

[0180] It should also be noted that the first front air duct 3 has an air duct profile surface 31 in its length direction that is adapted to at least part of the outer contour of the upper cylinder 1;

[0181] The first front air duct 3 is designed such that when the first front air duct 3 is fixedly assembled on the upper cylinder 1, the air duct profile surface 31 fits against at least part of the outer profile of the upper cylinder 1.

[0182] Since the air inlet of the upper drum 1 is located at the top of the door seal, the path of the first front air duct 3 is relatively long in order to achieve the drying function of the upper drum. In this embodiment of the invention, in order to improve the overall operational stability of the washing machine while extending the path of the first front air duct 3, an air duct contour surface 31 that matches the outer contour of the first outer drum is provided on the first front air duct 3. This can both extend the air duct path of the first front air duct 3 and prevent the side length of the path from affecting the operational stability of the machine.

[0183] Specifically, the first front air duct 3 includes a front air duct upper cover 3a and a front air duct lower cover 3b, which are detachably connected.

[0184] The air duct profile surface 31 includes an upper cover profile surface 311 formed along the length of the upper cover 3a of the front air duct and a lower cover profile surface 312 formed along the length of the lower cover 3b of the front air duct.

[0185] Preferably, the upper front air duct cover 3a and the lower front air duct cover 3b are detachably connected by screws.

[0186] In this embodiment of the invention, by setting the upper cover 3a and the lower cover 3b of the air duct to be detachable from the left and right, it is more conducive to the forming of parts and easier to assemble the air duct.

[0187] In any of the above embodiments, the main drying air duct is located between the bottom of the upper drum 1 and the top of the lower drum 2 in the height direction of the washing machine and is fixed to the top of the lower drum 2. The main drying air duct is located at a distance from the surface that passes through the rotation axis of the upper drum 1 and the rotation axis of the lower drum 2 in the width direction of the washing machine.

[0188] The rotation axis of the upper drum 1 and the rotation axis of the lower drum 2 coincide in the top view of the washing machine.

[0189] In this embodiment of the invention, by placing the connecting air duct assembly in the space between the upper cylinder 1 and the lower cylinder 2, the extra remaining space when the upper cylinder 1 and the lower cylinder 2 are arranged vertically is fully utilized. At the same time, by placing the air duct assembly connecting the upper cylinder 1 and the lower cylinder 2 on one side of the space between the upper cylinder and the lower cylinder, the space between the upper cylinder 1 and the lower cylinder 2 can be fully utilized while avoiding excessive bends in the air duct path that would affect the airflow effect.

[0190] In any of the above embodiments, the main drying air duct includes a fan section 7 and a heat exchange section 8 that are connected in sequence and in fluid communication, wherein the air inlet of the fan section 7 is connected to the air outlet of the second air distribution device, the air outlet is connected to the heat exchange section 8, and the air outlet of the heat exchange section 8 is connected to the air inlet of the first air distribution device.

[0191] The fan section 7 is equipped with a fan assembly, and the heat exchange section 8 is equipped with a drying assembly;

[0192] To better understand the air distribution principle of the air distribution device in the embodiments of this application, the following is combined with... Figure 6 and Figure 7 Please provide a detailed explanation:

[0193] Specifically, such as Figure 6 As shown, taking the first air distribution device 4 connecting the first front air duct 3 and the second front air duct 53 as an example, specifically, the first air distribution device 4 includes:

[0194] The air distribution box 41 and the air distribution component 42 are formed inside the air distribution box 41. The air distribution component is rotatably disposed in the air distribution cavity. The surface of the air distribution box 41 is formed with a first air outlet for connecting to the first front air duct 3 and a second air outlet for connecting to the second front air duct 53.

[0195] The air distribution component 42 is designed such that when the air distribution component 42 is driven to rotate, at least part of the first air outlet and / or at least part of the second air outlet can be opened to adjust the air flow rate from the first front air duct 3 into the upper cylinder 1, and to adjust the air flow rate from the second front air duct 53 into the lower cylinder 2.

[0196] In this embodiment of the invention, a rotatable air distribution component 42 is provided in the air distribution box 41 of the air distribution device 4. By controlling the rotation angle of the air distribution component 42, the upper cylinder 1 can be dried alone, the lower cylinder 2 can be dried alone, or the upper cylinder 1 or the lower cylinder 2 can be dried simultaneously, or the airflow input to each cylinder can be adjusted during drying.

[0197] More specifically, the air distribution chamber is a circular chamber, and the air distribution component 42 is an air distribution baffle that is rotatably installed in the air distribution chamber;

[0198] The air distribution baffle has an outer peripheral surface that fits into the air distribution cavity;

[0199] When the air distribution baffle is driven to rotate, the outer circumferential surface of the air distribution baffle can slide along the inner circumferential surface of the air distribution cavity.

[0200] It's worth noting that to achieve a specific drying effect in the washing machine (drying the upper drum 1 alone, drying the lower drum 2 alone, or drying both drums simultaneously), the air distribution baffle needs to be rotated at different angles. In actual products, to achieve a preset drying effect after the air distribution baffle rotates to a preset angle, this can be achieved by designing the dimensions of the air distribution baffle and / or the dimensions of the first and / or second air outlets of the connecting air duct assembly.

[0201] In any of the above embodiments, the heat exchange assembly includes a two-phase assembly, which includes an evaporator and a condenser connected by a refrigerant line.

[0202] The washing machine also includes a compressor 9, which is connected to the condenser via a refrigerant line;

[0203] The washing machine also includes a cabinet, and the compressor 9 is fixedly installed inside the bottom of the washing machine cabinet.
