[0088] Background

[0089] Currently, most multi-drum washing machines on the market still have manual door opening, which is extremely inconvenient when the user is holding clothes or carrying things. There is also a risk of high-temperature gas burning the user when the door is opened if the temperature inside the drum is too high.

[0090] Based on this, Figure 1-Figure 7 As shown, a first aspect of an embodiment of the present application provides a door opening control method for a fabric processing device, wherein the fabric processing device includes multiple fabric processing drums, and the multiple fabric processing drums share the same drying system; the drying system includes a main drying duct and multiple air inlets and multiple air outlets connected on both sides of the inlet and outlet of the main drying duct, the air outlets of the multiple air inlets are connected one-to-one with the air inlets of the multiple fabric processing drums, and the air inlets of the multiple air outlets are connected one-to-one with the air outlets of the multiple fabric processing drums, and an air distribution device is provided between the air inlet of the main drying duct and the air outlets of the multiple air outlets and / or between the air outlet of the main drying duct and the air inlets of the multiple air inlets. By controlling the air distribution device, the air flow between at least two fabric processing drums can be conducted, and the door opening control method includes:

[0091] When the target fabric processing drum that is in a high-temperature operation state or has not finished the high-temperature operation state for a preset time receives a drum door opening signal, the drum temperature information of the target fabric processing drum is obtained;

[0124] Furthermore, a second aspect of an embodiment of the present application further provides a door opening control method for a fabric processing device, wherein the fabric processing device includes multiple fabric processing drums, and the multiple fabric processing drums share the same drying system; the drying system includes a main drying duct and multiple air inlets and multiple air outlets connected on both sides of an inlet and outlet of the main drying duct, the air outlets of the multiple air inlets are connected one-to-one with the air inlets of the multiple fabric processing drums, and the air inlets of the multiple air outlets are connected one-to-one with the air outlets of the multiple fabric processing drums, and an air distribution device is provided between the air inlet of the main drying duct and the air outlets of the multiple air outlets and / or between the air outlet of the main drying duct and the air inlets of the multiple air inlets. By controlling the air distribution device, the air flow between at least two fabric processing drums can be conducted, and the door opening control method includes:

[0125] Door opening control methods include:

[0126] In response to a second sensing signal indicating that the doors of the plurality of target fabric processing drums are simultaneously opened, obtaining temperature information inside the plurality of target fabric processing drums;

[0127] Determining whether multiple target fabric processing drums meet door opening conditions, where the door opening conditions at least meet the requirement that the temperature inside the drum is lower than a set value;

[0128] If the multiple target fabric processing drums all meet the door opening condition, then the drum doors of the multiple target fabric processing drums are opened;

[0129] If at least one of the multiple target fabric processing drums does not meet the door opening condition, obtaining status information of whether at least one of the multiple target fabric processing drums meets the requirement of performing ventilation and cooling treatment on the target fabric processing drum that does not meet the door opening condition;

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

[0131] That is, when the doors of multiple target tubes receive opening instructions at the same time, when at least one target tube does not meet the door opening conditions, and at least one target tube can cool down the target tube that does not meet the door opening conditions, the air distribution device can be controlled to make the target tube with a low temperature inside the tube cool down the target tube with a high temperature inside the tube, thereby avoiding the high-temperature airflow that easily burns the user when the door is opened directly, and shortening the waiting time for opening the target tube.

[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, wherein the air inlet end of the first air distribution device is connected to the air outlet ends of the multiple air outlet ducts, and the air inlet ends of the multiple air outlet ducts are connected to the air outlets of the multiple fabric processing drums in a one-to-one correspondence, and the air outlet end of the second air distribution device is connected to the air inlet ends of the multiple air inlet ducts, and the air outlet ends of the multiple air inlet ducts are connected to the air inlets of the multiple fabric processing drums in a one-to-one correspondence; the first air distribution device can be controlled to make the air inlet of the main drying air duct selectively connected to one or more of the multiple air outlet ducts and to make the multiple air outlet ducts selectively connected, and the second air distribution device can be controlled to make the air outlet of the main drying air duct selectively connected to one or more of the multiple air inlet ducts and to make the multiple air inlet ducts selectively connected;

[0133] Controlling the air distribution device to make the air in the target fabric treatment cylinder that meets the ventilation and cooling treatment requirements flow 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 drum that does not meet the door opening condition, and the air inlet of the main drying air duct is connected to the air outlet of the target fabric processing drum 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 drum that does not meet the door opening condition, and the air outlet of the main drying air duct is disconnected from the air inlet of the target fabric processing drum that meets the ventilation and cooling requirements.

[0135] Furthermore, in some possible embodiments, the fabric processing device further includes a fan assembly disposed in the main drying air duct;

[0136] The control method also includes:

[0137] If the multiple target fabric processing drums do not meet the door opening condition, the air supply of the fan assembly is increased to cool the multiple target fabric processing drums by increasing the air volume entering the multiple target fabric processing drums.

[0138] Furthermore, in some possible implementations, the door opening condition of the target fabric treatment drum also needs to satisfy that the target fabric treatment drum is not in a high-temperature operation state or the target fabric treatment drum has ended the high-temperature operation state for more than a preset time;

[0139] The door opening control method also includes:

[0140] If the target fabric processing drum is in a high-temperature operation state, the target fabric processing drum is controlled to stop the high-temperature operation state.

[0141] Specifically, in some possible implementations, obtaining status information of whether at least one target fabric processing drum among a plurality of target fabric processing drums meets the requirement of performing ventilation and cooling treatment on the target fabric processing drum that does not meet the door opening condition includes:

[0142] Determine whether there is a target fabric processing drum that is in a non-high temperature operation state and whose internal temperature is lower than a set value;

[0143] If so, it is determined that the target fabric treatment drum meets the requirements for performing ventilation cooling treatment on other target fabric treatment drums.

[0144] Further, in some possible embodiments, the plurality of fabric processing drums include an upper drum and a lower drum, and the fabric processing device further includes a first sensor, a second sensor, and a third sensor, wherein the first sensor, the second sensor, and the third sensor are all disposed at the bottom of the lower drum and distributed laterally along the lower drum;

[0145] The control method also includes:

[0146] When the first sensor, the second sensor and the third sensor are triggered in sequence, a double-barrel door simultaneous opening signal is sent.

[0147] In combination with the contents of the first and second aspects of the above-mentioned embodiments, it can be seen that in the embodiments of the present application, by providing a plurality of fabric processing drums on the fabric processing device and providing a plurality of sensors on the fabric processing device, when it is necessary to open a certain drum or multiple drums of the fabric processing device, the triggering conditions of the multiple sensors can be changed to enable the fabric processing device to automatically open the corresponding drum door. At the same time, when opening the corresponding drum door, by obtaining the status information of the target fabric processing drum and combining the status information to selectively control the connectivity status between the multiple drums and / or the operating parameters of the multiple drums, the fabric processing device can automatically open the drum door at the most appropriate time, thereby avoiding the risk of accidents caused by the incorrect opening timing of the drum door.

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

[0149] That is, in the embodiment of the present application, when sensors at different positions and / or different numbers of sensors and / or multiple sensors are triggered in different triggering orders, the sensing device can send different sensing signals, and the controller can determine the target fabric processing drum whose drum door needs to be opened based on the different sensing signals.

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

[0151] When it is recognized that the user intends to open the door of a single drum, it is determined whether the drum meets the door opening conditions. If so, the door is opened. If not, the reason why the door cannot be opened and the waiting time are prompted on the display screen. Specifically, if the drum is drying and has exceeded the door opening temperature, it is determined whether another drum is drying. If so, the air distribution device is used to direct all the hot air to the other drum, and the target door opening drum waits for the temperature to drop to meet the door opening conditions before performing the door opening action. If the other drum is not drying and the drum temperature is low, the heat exchange module stops heating, and at the same time the air distribution device directs the cool air of the other drum to the target door opening drum to achieve the effect of rapid cooling.

[0152] When it is recognized that the user intends to open the door of the double drum, it is determined whether the double drum meets the door opening conditions. If the door opening conditions are not met, the reason for not being able to open the door and the waiting time will be prompted on the display screen; specifically, if a single drum is drying, after receiving the door opening command, the heat exchange component stops heating, and the air distribution device guides cool air to the drum to cool it down. When the temperature drops to a safe temperature, the door lock is unlocked and the door is opened; if both drums are drying, after receiving the double drum door opening command, the heat exchange component stops heating, and the fan component increases the air volume to quickly cool down the double drum. When the temperature drops to a safe temperature, the double drum door lock is unlocked and the door is opened.

[0153] It can be seen that in the embodiment of the present application, the above-mentioned control logic can realize the automatic door opening operation of the fabric processing equipment, and can also ensure that the fabric processing equipment can open the door under the most appropriate circumstances, avoiding the risk of accidents caused by the wrong opening timing of the drum door.

[0154] It should be noted that, in the embodiment of the present application, only by triggering the multiple sensors in a specific order can the sensing device emit a corresponding sensing signal, thereby avoiding the situation of mistakenly opening the door. Preferably, the multiple sensors are all infrared sensors.

[0155] In some specific implementations, the automatic door opening operation can be achieved through the user's leg sweeping action. Specifically, different leg sweeping actions correspond to different infrared sensors. When judging whether a single drum door is open, the user can set the middle infrared sensor in combination with one of the sensors on both sides as the judgment condition for opening the door, that is, in a short-stroke leg sweeping action, blocking the middle sensor in combination with one of the sensors on both sides can open a single door body; when the double-drum door bodies need to be opened at the same time, the user can perform a long-stroke leg sweeping action, that is, after blocking the three sensors by the leg sweeping action, the system determines that the double-drum door bodies are opened at the same time. The multi-drum washing machine shares an air duct of a heating module, and an air distribution device is provided in the air duct to direct air to each drum. When the user determines whether a single drum door is opened or a double drum door is opened through the leg sweeping action, it is determined whether the drum exceeds the door opening setting temperature. If so, the heating module is paused. If the other drum is not drying, the air distribution device directs cool air to the drum with too high a temperature to cool it down.

[0156] Furthermore, the third aspect of the embodiment of the present application also provides a fabric processing device, which adopts the door opening control method provided by the first aspect of the embodiment of the present application and / or the door opening control method provided by the second aspect of the embodiment of the present application.

[0157] In order to understand more clearly how the air distribution device in the fabric processing equipment guides the air flow in one cylinder into another cylinder, the following is combined with Figure 4-Figure 7 To explain in detail:

[0158] First, a fabric processing device is introduced. Taking the fabric processing device as a twin-drum washing machine having an upper drum 1 and a lower drum 2 as an example, the upper drum 1 includes a first outer drum and a first inner drum pivotally arranged in the first outer drum, and the lower drum 2 includes a second outer drum and a second inner drum pivotally arranged in the second outer drum;

[0159] The air distribution device, the upper drum 1 and the lower drum 2 are connected through the air distribution device, and the upper drum 1 and the air distribution device form a first circulation air duct, and the lower drum 1 and the air distribution device form a second circulation air duct; specifically, the first circulation air duct and the second circulation air duct share a main drying air duct, and 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, wherein the air inlet end of the first air distribution device is connected to the air outlet end of multiple air outlet ducts, and the air inlet ends of the multiple air outlet ducts are connected to multiple fabric processing The air outlets of the fabric processing drums are connected one-to-one, the air outlet end of the second air distribution device is connected to the air inlet ends of the multiple air inlet ducts, and the air outlet ends of the multiple air inlet ducts are connected one-to-one to the air inlets of the multiple fabric processing drums; the first air distribution device can be controlled to make the air inlet of the main drying air duct selectively connected to one or more of the multiple air outlets and to make the multiple air outlets selectively connected, and the second air distribution device can be controlled to make the air outlet of the main drying air duct selectively connected to one or more of the multiple air inlet ducts and to make the multiple air inlet ducts selectively connected;

[0160] The vibration reduction system includes a first vibration reduction system provided in the upper tube 1 and a second vibration reduction system (not shown in the figure) provided in the lower tube 2. The first vibration reduction system and the second vibration reduction system can both be a vibration reduction system composed of a spring and a damper.

[0161] In the embodiment of the present invention, two sets of air distribution devices are provided between the upper drum 1 and the lower drum 2. On the one hand, the two sets of air distribution devices can make the upper drum 1 and the lower drum 2 share an air duct, without adding an additional air duct, thereby reducing the size and manufacturing cost of the washing machine. On the other hand, the two sets of air distribution devices 4 can also connect the upper drum 1 and the lower drum 2, thereby improving the rigidity during double-drum operation. When the double drums are in operation, the vibrations of the double drums can be transmitted to each other through the air distribution device, and the vibrations are ultimately eliminated by the vibration reduction systems of the two drums. Each single drum has a vibration reduction system composed of a hanging spring + a damper, that is, the two drums connected by a common air duct can transmit the vibrations to the vibration reduction systems of the two drums through the connection of the common air duct during operation, thereby enhancing the stability and reliability of the double-drum operation. On the other hand, when the upper drum and / or the lower drum needs to open the door, the airflows in the two drums can be mixed together in different ways by the two sets of air distribution devices, so as to quickly reduce the temperature in the target door-opening drum.

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

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

[0164] The front air duct assembly includes two air inlets connected to the 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 tube 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 tube 2.

[0165] The rear air duct assembly includes a first rear air duct 6 and a second rear air duct 10 connected to the two air inlets of the second air distribution device, wherein 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 tube 1, and 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 tube 2;

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

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

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

[0169] Specifically, the first front air duct 3 is fixedly connected to the upper tube 1 and softly connected to the middle air duct, and the second front air duct 53 is softly connected to the lower tube 2 and softly 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 in sequence from top to bottom;

[0171] Among them Figure 4-Figure 6 As shown, the communication position between the air duct outlet of the first front air duct 3 and the upper tube 1 is located at the top position of the door seal of the upper tube 1; the communication position between the air duct outlet of the second front air duct 53 and the lower tube 2 is located at the top position of the door seal of the lower tube 2.

[0172] It is worth noting that when the upper cylinder 1 and the lower cylinder 2 in the embodiment of the present invention are distributed up and down, the upper cylinder 1 located at the top is higher and lighter, and is prone to shaking. Therefore, by providing a first front air duct 3 fixedly assembled with the upper cylinder 1, the upper cylinder 1 can be counterweighted, thereby improving the operating stability of the entire machine.

[0173] At the same time, since the first front air duct 3 is fixedly assembled on the upper tube 1, when the upper tube 1 shakes, the collision between the first front air duct 3 and the upper tube 1 can be avoided {since the first front air duct 3 is fixedly assembled with the upper tube 1, when the upper tube 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 softly connected to the upper tube 1 and the second air distribution device, and the second rear air duct 10 is fixedly connected to the lower tube 2 and 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 in sequence from top to bottom.

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

[0178] It should also be noted that the material of the soft connector 52 used in the embodiment of the present invention only needs to have a certain supporting effect when receiving a smaller impact force and a certain elastic deformation effect when receiving a larger impact force. The specific material of the soft connector is not limited in the embodiment of the present invention.

[0179] In the embodiment of the present invention, the air duct is connected by providing a soft connector, which can ensure the transmission of vibration force on the one hand, and on the other hand, avoid damage to the connection position caused by excessive vibration force while ensuring the transmission of vibration force.

[0180] It should also be noted that the first front air duct 3 has an air duct contour surface 31 in its length direction that is adapted to at least a portion of the outer contour of the upper tube 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 tube 1 , the air duct contour surface 31 is in contact with at least a portion of the outer contour of the upper tube 1 .

[0182] Because the air inlet of the upper drum 1 is located at the top of the door seal, the first front air duct 3 is relatively long to achieve the upper drum's drying function. In this embodiment of the present invention, to improve the overall operating stability of the washing machine while extending the path of the first front air duct 3, a duct contour surface 31 is provided on the first front air duct 3 that matches the outer contour of the first outer drum. This not only extends the air duct path of the first front air duct 3, but also does not affect the operating stability of the machine due to the length of the path.

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

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

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

[0186] In the embodiment of the present invention, the air duct upper cover 3a and the air duct lower cover 3b are arranged to be disassembled left and right, which is more conducive to the molding 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 in the width direction of the washing machine at a distance from a plane passing through the rotation axis of the upper drum 1 and the rotation axis of the lower drum 2.

[0188] The rotation axis of the upper drum 1 and the rotation axis of the lower drum 2 coincide with each other when viewed from above the washing machine.

[0189] In the embodiment of the present invention, the connecting air duct assembly is arranged in the space between the upper tube 1 and the lower tube 2, thereby fully utilizing the extra remaining space when the upper tube 1 and the lower tube 2 are arranged up and down. At the same time, the air duct assembly connecting the upper tube 1 and the lower tube 2 is arranged on one side of the space between the upper tube 1 and the lower tube. While fully utilizing the space between the upper tube 1 and the lower tube 2, it is possible to avoid excessive bending in the air duct path to affect the flow effect of the airflow.

[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 sequentially connected and fluidly communicated with each other, wherein the air inlet end of the fan section 7 is connected to the air outlet of the second air distribution device, and the air outlet end is connected to the heat exchange section 8, and the air outlet end of the heat exchange section 8 is connected to the air inlet of the first air distribution device;

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

[0192] In order to more clearly understand the air distribution principle of the air distribution device in the embodiment of the present application, the following Figure 6 and Figure 7 To explain in detail:

[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 member 42 are provided with an air distribution cavity inside the air distribution box 41. The air distribution member is rotatably arranged in the air distribution cavity. The surface of the air distribution box 41 is provided with a first air outlet for communicating with the first front air duct 3 and a second air outlet for communicating with the second front air duct 53.

[0195] The air distribution member 42 is designed to open at least part of the first air outlet and / or at least part of the second air outlet when the air distribution member 42 is driven to rotate, so as to adjust the amount of air entering from the first front air duct 3 into the upper tube 1, and to adjust the amount of air entering from the second front air duct 53 into the lower tube 2.

[0196] In the embodiment of the present invention, a rotatable air distribution member 42 is provided in the air distribution box 41 of the air distribution device 4. By controlling the rotation angle of the air distribution member 42, it is possible to dry the upper drum 1 alone or the lower drum 2 alone or dry the upper drum 1 or the lower drum 2 at the same time, or adjust the air flow input to each drum during drying.

[0197] More specifically, the air distribution cavity is a circular cavity, and the air distribution member 42 is an air distribution baffle rotatably disposed in the air distribution cavity;

[0198] The air distribution baffle has an outer peripheral surface that is arranged in contact with the air distribution cavity;

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

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

[0201] In any of the above embodiments, the heat exchange assembly includes a two-device assembly, and the two-device assembly includes an evaporator and a condenser connected through a refrigerant pipeline;

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

[0203] The washing machine further comprises a housing, and the compressor 9 is fixedly mounted at the inner bottom end of the washing machine housing.
