[0037] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising that element. "Plurality" means greater than or equal to two.

[0038] A switching device provided by an embodiment of the present invention can be used in household electrical appliances, for example, in laundry treatment equipment. The laundry treatment equipment can be an all-in-one washing and drying machine with washing and drying functions, or a clothes dryer that independently performs the clothes drying function without washing function. It should be noted that the application scenario type of the present invention does not limit the switching device of the embodiment of the present invention. The laundry treatment equipment with the above switching device has both a working state of drying clothes and a working state of environmental dehumidification. The working principles of the laundry treatment equipment in the above two working states are described below.

[0039] As Figures 1 - 3 shown, the laundry treatment equipment includes: a barrel body 4, a housing 2, a drying assembly 3, and a switching device 1. Among them, as Figure 2 shown, the barrel body 4 has an accommodation cavity 41 for accommodating clothes inside, and an opening is provided at the front end ( Figure 2 the right end shown) of the barrel body 4 for taking in and out clothes from the accommodation cavity 41. The barrel body 4 is arranged inside the housing 2, and a drying channel 33 is formed between the housing 2 and the barrel body 4. Among them, the drying channel 33 and the accommodation cavity 41 can be communicated. Specifically, the opening at the front end ( Figure 2 the right end shown) of the barrel body 4 can be communicated with the drying channel 33, and the rear end ( Figure 2The left end shown) may also be provided with a through hole communicating with the drying channel 33. Among them, the switching device 1 may be provided near the front end of the barrel body 4. By changing the state of the switching device 1, the communication relationship between the drying channel 33 and the accommodating cavity 41 and the external environment is switched, so as to change the working state of the laundry treatment device. A drying assembly 3 is provided in the drying channel 33 to dry the air flow. Among them, the drying assembly 3 may include an evaporator 31 and a condenser 32.

[0040] As Figure 2 shown, when the laundry treatment device is in the working state of environmental dehumidification, the arrow direction is the air flow direction. When the corresponding switching device 1 is in the first state, the switching device 1 cuts off the communication relationship between the front end opening of the accommodating cavity 41 and one end of the drying channel 33, and makes the external environment (the environment outside the laundry treatment device) communicate with the drying channel 33 and the front end opening of the accommodating cavity 41 communicate. Then, the external humid air flow enters the drying channel 33 and passes through the evaporator 31 and the condenser 32 in sequence. The evaporator 31 absorbs heat to cool and dehumidify, and the condenser 32 releases heat to heat the air. Thus, the external humid air flow is dried after passing through the drying channel 33. Since the other end of the drying channel 33 is communicated with the accommodating cavity 41 ( Figure 2 shown as the left end of the accommodating cavity 41), the dry air flow enters and passes through the accommodating cavity 41, and flows back to the external environment through the front end opening of the accommodating cavity 41, thus realizing the function of dehumidifying the air flow in the external environment. When the laundry treatment device is in the working state of environmental dehumidification, the air flow circulates between the inside and the outside (in the environment) of the housing 2, hereinafter referred to as the external circulation.

[0041] As Figure 3 shown, when the laundry treatment device is in the working state of drying clothes, the arrow direction is the air flow direction. When the corresponding switching device 1 is in the second state, the switching device 1 makes the front end opening of the accommodating cavity 41 communicate with one end of the drying channel 33, and cuts off the communication relationship between the external environment and the drying channel 33 and the front end opening of the accommodating cavity 41. Then, the wet clothes in the accommodating cavity 41 make the air flow in the accommodating cavity 41 be a wet air flow. The wet air flow enters the drying channel 33 through the front end opening of the accommodating cavity 41 and passes through the evaporator 31 and the condenser 32 in sequence. The evaporator 31 absorbs heat to cool and dehumidify, and the condenser 32 releases heat to heat the air. Thus, the wet air flow is dried after passing through the drying channel 33. Since the other end of the drying channel 33 is communicated with the accommodating cavity 41 ( Figure 3If it is connected to the left end of the accommodation chamber 41, then the dry air flow enters and passes through the accommodation chamber 41 to dry the damp clothes in the accommodation chamber 41. The dry air flow becomes damp again, and then enters the drying channel 33 through the front end opening of the accommodation chamber 41 to start the next cycle, thus realizing the function of drying the clothes in the accommodation chamber 41. When the clothing treatment device is in the working state of drying clothes, the air flow circulates inside the housing 2, hereinafter referred to as the internal circulation.

[0042] Among them, as Figure 2 and Figure 3 shown, a third baffle 5 is also provided in the clothing treatment device to cooperate with the state of the clothing treatment device. In the Figure 2 shown external circulation state, the third baffle 5 is opened so that the external air flow and the air flow inside the clothing treatment device can circulate. In the Figure 3 shown internal circulation state, the third baffle 5 is closed so that the external air flow and the air flow inside the clothing treatment device cannot circulate.

[0043] The switch device 1 provided by the embodiment of the present invention will be described below.

[0044] As Figure 4 shown, the switch device 1 includes a box body 10 and a movable member 11. Among them, a cavity 12 is provided inside the box body 10. The box body 10 is a hollow component, and the cavity 12 can be communicated with the external space of the box body 10 so that air flow can enter and exit the cavity 12. Among them, the box body 10 is provided with a first opening 13, a second opening 14, and a third opening 15 that are communicated with the cavity 12. The second opening 14 and the third opening 15 are oppositely arranged on both sides of the first opening 13. For example, taking the Figure 4 set orientation as an example for description, the first opening 13 can be an opening provided on the top and side, and the second opening 14 and the third opening 15 are openings provided on the front and rear end faces of the box body 10.

[0045] Combined with Figures 1 - 3 shown, taking the case where the switch device 1 is applied to a clothing treatment device as an example for description, the first opening 13 can communicate the cavity 12 and the accommodation chamber 41 so that air flow can be conducted between the cavity 12 and the accommodation chamber 41; the second opening 14 can communicate the cavity 12 and the outside (in the environment), so that the external air flow can enter the switch device 1 through the second opening 14 and the air flow inside the cavity 12 of the switch device 1 can flow out through the second opening 14. The third opening 15 can communicate the cavity 12 and the drying channel 33 so that gas can enter the drying channel 33 from the cavity 12.

[0046] Figure 2 The dehumidification working state shown corresponds to the switch device being in Figures 4 - 5The first state, specifically, the first opening 13 communicates with the second opening 14, so that the gas in the accommodation cavity 41 can flow from the first opening 13 to the second opening 14 and then to the outside; the third opening 15 communicates with the second opening 14, so that the gas outside can flow from the second opening 14 to the cavity 12 and then from the cavity 12 to the drying channel 33 through the third opening 15; the first opening 13 and the third opening 15 are not in communication, so that the gas in the accommodation cavity 41 does not circulate back into the drying channel 33 again, thereby realizing the dehumidification of the air outside the laundry treatment device.

[0047] Figure 3 The drying working state shown corresponds to the switch device being in Figures 6 - 7 The second state, specifically, the first opening 13 communicates with the third opening 15, so that the gas in the accommodation cavity 41 can enter the cavity 12 from the first opening 13, and the gas in the cavity 12 then enters the drying channel 33 from the third opening 15, and the gas circulates between the accommodation cavity 41 - cavity 12 - drying channel 33, thereby realizing the drying of the clothes in the accommodation cavity 41.

[0048] As Figure 4 shown, the movable member 11 is movably connected to the box body 10 to switch the communication state of at least two of the first opening 13, the second opening 14, and the third opening 15. Among them, the connection method between the movable member 11 and the box body 10 includes various types. For example, the movable member 11 can be translationally connected to the box body 10, the movable member 11 can also be rotationally connected to the box body 10, and the movable member 11 can also be movably connected to the box body 10 through a combination of translation and rotation. During the movement of the movable member, the movable member 11 can switch the communication state of each opening on the box body 10 to realize different air guiding states of the switch device 1; for example, switching the communication state between the first opening and the third opening and / or the communication state between the second opening and the third opening and / or switching the communication state between the first opening and the second opening. Taking the laundry treatment device as an example, the movable member 11 can move between the above-mentioned first state and the second state to realize the switching of the two air guiding states of the internal circulation and the external circulation of the laundry treatment device, and further realize the switching of the two working states of drying and dehumidification of the laundry treatment device.

[0049] An embodiment of the present invention provides a switch device, which includes a box body and a movable member. A cavity is provided inside the box body. The box body is provided with a first opening, a second opening, and a third opening that communicate with the cavity. The movable member is movably connected to the box body to switch the communication state of at least two of the first opening, the second opening, and the third opening. By movably connecting the movable member to the box body in the embodiment of the present invention, the movable member can be switched in multiple states so that at least two openings in the box body communicate, thereby realizing the switching of the air flow direction in the switch device. The switch device in the embodiment of the present invention has a simple structure and is convenient to operate.

[0050] In some embodiments, such as Figure 4 and Figure 5 shown, the movable member 11 extends from the top wall 16 of the box body 10 to the bottom wall 17 of the box body 10. The bottom wall 17 is disposed opposite to the top wall 16. The movable member 11 may be a flat plate structure or a bent structure. The extension means that one end of the movable member 11 in the length direction ( Figure 4 the upper end in the z direction shown) is close to the top wall 16 of the box body 10, and the other end of the movable member 11 in the length direction ( Figure 4 the lower end in the z direction shown) is close to the bottom wall 17 of the box body 10. It should be noted that "close" means that there may be a direct contact relationship between the movable member 11 and the box body 10, or the distance between the movable member 11 and the box body 10 is small, making it less likely for gas to conduct through the gap between the movable member 11 and the box body 10.

[0051] Among them, as Figure 4 shown, at least part of the top wall 16 is provided with the first opening 13. That is to say, the first opening 13 may be composed of multiple parts. As long as the switching device 1 is arranged in the laundry treatment device, the first opening 13 communicates the cavity 12 with the accommodating cavity 41. Figure 4 In the shown embodiment, the first opening 13 is composed of two parts. One part of the first opening 13 is arranged on the top wall 16, and the other part of the first opening 13 is arranged on the side wall 18. The side wall 18 connects the top wall 16 and the bottom wall 17. The other part of the first opening 13 is arranged close to one part of the first opening 13, so that both parts of the first opening 13 communicate the accommodating cavity 41 and the cavity 12. In the embodiments of the present invention, by increasing the area and number of the first opening 13, the efficiency of gas conduction between the accommodating cavity and the cavity is improved.

[0052] Such as Figure 4 shown, the movable member 11 can rotate around the first edge 11a to switch the communication state. The first edge 11a is the edge of the movable member 11 extending from the top wall 16 to the bottom wall 17. Such as Figure 4 shown, the box body 10 may be similar to a frame structure. The second opening 14 in the box body 10 may be arranged on one side of the box body 10 ( Figure 4 the positive side of the y-axis in), and the first edge 11a may be the edge of the movable member 11 located at the second opening 14. One end of the first edge 11a ( Figure 4 the upper end in the z direction shown) can be connected to the top wall 16, and the other end of the first edge 11a ( Figure 4 the lower end in the z direction shown) can be connected to the bottom wall 17. In the embodiments of the present invention, the communication state is switched by the form of the movable member rotating around the first edge, and the connection method is simple and the switching is convenient, which is beneficial to improving the comfort and smoothness of user switching.

[0053] In some embodiments, as Figure 4 shown, the movable member 11 includes a first baffle 111 and a second baffle 112. The first baffle 111 includes a first edge 11a and a second edge 11b. Among them, the second edge 11b is disposed opposite to the first edge 11a. As Figure 4 shown in the embodiment, the first edge 11a is located on one side of the width direction of the first baffle 111 ( Figure 4 the positive side of the y-axis shown), and the second edge 11b is located on the other side of the width direction of the first baffle 111 ( Figure 4 the negative side of the y-axis shown). The first edge 11a of the first baffle 111 is disposed in the second opening 14, so that the first baffle 111 divides the second opening 14 into two parts; combined with Figure 5 shown, in the first state, the second edge 11b of the first baffle 111 is disposed in the third opening 15, so that the first baffle 111 divides the third opening 15 into two parts. The opposite sides of the first baffle 111 are respectively disposed in the second opening 14 and the third opening 15, so that the first baffle 111 can divide the cavity 12 into two sub-cavities in the first state. The two sub-cavities are a first sub-cavity 121 and a second sub-cavity 122 respectively. The first sub-cavity 121 communicates with the first opening 13 and the second opening 14, and the second sub-cavity 122 communicates with the second opening 14 and the third opening 15.

[0054] Combined with Figure 2 shown, when the connection state of the switching device is Figures 4 - 5 the first state described, the external gas can enter the second sub-cavity 122 from the second opening 14. The gas in the second sub-cavity 122 then enters the drying channel 33 from the third opening 15 for dehumidification of the gas. The dehumidified gas flows into the accommodation cavity 41. The gas in the accommodation cavity 41 flows from the first opening 13 to the first sub-cavity 121, and the gas in the first sub-cavity 121 flows from the second opening 14 to the outside of the laundry treatment device.

[0055] As Figure 4 shown, the second baffle 112 includes a third edge 11c and a fourth edge 11d. The third edge 11c is disposed opposite to the fourth edge 11d, Figure 4 in the embodiment shown, the third edge 11c is located on one side of the width direction of the second baffle 112 ( Figure 4 the negative side of the x-axis shown), and the fourth edge 11d is located on the other side of the width direction of the second baffle 112 ( Figure 4 the positive side of the x-axis shown). As Figure 4As shown in the figure, both the third edge 11c and the fourth edge 11d of the second baffle 112 are disposed in the third opening 15, such that the portion of the third opening 15 located in the first sub-chamber 121 is blocked by the second baffle 112. As a result, the air flow entering the first sub-chamber 121 from the first opening 13 cannot flow to the second sub-chamber 121 and then out of the third opening 15 due to the blockage of the first baffle 111, and cannot directly flow out of the third opening 15 due to the blockage of the second baffle 112. Thus, the communication between the first opening 13 and the third opening 15 is blocked, and the air flow entering the first sub-chamber 121 from the first opening 13 can only directly flow out from the second opening 14.

[0056] As Figure 4 shown, the third edge 11c is connected to the second edge 11b of the first baffle 111, and the third edge 11c can rotate around the second edge 11b. During the process of the movable component 11 switching from the Figures 4 - 5 first state shown in the figure to the Figures 6 - 7 second state shown in the figure, the first baffle 111 rotates around the first edge 11a, and the second edge 11b follows the movement of the first edge 11a, thereby driving the movement of the third edge 11c, and further realizing the driving of the second baffle 112 by the first baffle 111. It should be noted that the process described in the above embodiments is only used to define the connection relationship between the first baffle 111 and the second baffle 112, and does not limit the initiative of the movement between the first baffle 111 and the second baffle 112. During the movement, it can be the first baffle 111 as the active component driving the second baffle 112 to move, or the second baffle 112 as the active component driving the first baffle 111 to move. The specific active component is related to the position of the external force acting on the movable component 11, and the embodiments of the present invention do not make a limitation.

[0057] Combined with Figures 2 - 7 shown in the figure, the principle of the switching of the movable component 11 between the first state and the second state is described as follows:

[0058] As Figure 2 , Figure 4 and Figure 5 shown, in the first state, the first baffle 111 divides the cavity 12 into a first sub-chamber 121 and a second sub-chamber 122. The second baffle 112 closes the third opening 15 located in the first sub-chamber 121. The first opening 13 communicates the first sub-chamber 121 with the accommodation chamber 41. The third opening 15 located in the second sub-chamber 122 communicates the second sub-chamber 122 with the drying channel 33. The second opening 14 communicates with the outside of the laundry treatment device. The external gas can enter the drying channel 33 from the second sub-chamber 122, and the dry gas in the accommodation chamber 41 can flow from the first sub-chamber 121 to the outside, thereby playing a role in dehumidifying the external environment.

[0059] During the movable component 11 fromFigures 4 - 5 During the process of switching from the first state shown to Figures 6 - 7 the second state shown, the first baffle 111 rotates around the first edge 11a. For example, from Figure 4 the state shown, the first baffle 111 rotates around the first edge 11a to the left ([[]] Figure 4 in the direction of the rotation arrow shown). Since the third edge 11c of the second baffle 112 is rotatably connected to the second edge 11b of the first baffle 111, the second baffle 112 moves following the first baffle 111. When the first baffle 111 rotates 90 degrees to the left, that is, when the second edge 11b of the first baffle 111 reaches the second opening 14, the switching of the movable member 11 to the second state is completed.

[0060] As Figure 3 , Figure 6 and Figure 7 shown, in the second state, the first baffle 111 rotates approximately 90 degrees relative to the position of the first baffle in the first state while keeping the position of the first edge 11a unchanged. The first baffle 111 blocks a part of the second opening 14, and the blocked part is located on the left side of the first edge 11a as Figure 6 shown; the second baffle 112 moves with the first baffle 111 to be entirely within the second opening 14. Specifically, the third edge 11c of the second baffle 112 coincides with the second edge 11b of the first baffle 111. When the length of the second baffle 112 from the third edge 11c to the fourth edge 11d is greater than the length of the first baffle 111 from the first edge 11a to the second edge 11b, then a part of the second baffle 112 overlaps with the first baffle 111, and another part of the second baffle 112 blocks another part of the second opening 14, and the blocked another part is located on the right side of the first edge 11a. It should be noted that in other embodiments, it is also possible to change the extension lengths of the first baffle 111 and the second baffle 112 such that in the second state, the first baffle 111 and the second baffle 112 can also block the entire second opening 14 to isolate the outside from the cavity 12; or, the second baffle 112 is equal to or less than the length of the first baffle 111 such that the second baffle 112 does not block another part of the second opening 14 in the second state. Among them, when the first baffle 111 and the second baffle 112 block a part of the second opening 14, a shielding member can be further provided on the laundry treatment device to block the second opening.

[0061] In some embodiments, as Figures 8 - 9 shown, the first baffle 111 and the second baffle 112 are rotatably connected, where, as Figure 8As shown, a first rotating shaft 111a is provided at a first edge 11a of the first baffle 111, and the first rotating shaft 111a is rotatably connected to the box body. A rotating shaft mounting hole 111b is provided at a second edge 11b of the first baffle 111. As Figure 9 shown, a second rotating shaft 112a is provided at a third edge 11c of the second baffle 112, and the second rotating shaft 112a is connected to the rotating shaft mounting hole 111b of the first baffle 111, so that the second baffle 112 can rotate relative to the first baffle 111. In the embodiment of the present invention, by connecting the first baffle and the second baffle through a rotating shaft and a rotating shaft mounting hole, the connection method between the first baffle and the second baffle is simple and the installation is convenient.

[0062] In some embodiments, as Figure 9 shown, the movable member 11 further includes a handle 19, and the handle 19 protrudes on the first baffle 111 or the second baffle 112. Figure 9 In the shown embodiment, the handle 19 is disposed at a position close to the fourth edge 11d in the second baffle 112. Combining Figure 4 shown, and the handle 19 is located in the first sub-chamber 121 in the first state. In other embodiments, the handle 19 can protrude on the first baffle 111, and the handle 19 is located in the second sub-chamber 122 in the first state. In the embodiment of the present invention, by providing the handle, it is convenient for the user to apply force to the movable member, which is beneficial to reducing the difficulty of switching between the two working states.

[0063] In some embodiments, as Figures 10 - 15 shown, the switch device 1 further includes an adsorbing member disposed on the movable member 11 and / or the box body 10. It should be noted that the type of the adsorbing member disposed in the embodiment of the present invention is not limited, as long as the adsorbing member can fix the communication state of the movable member 11 and / or the box body 10.

[0064] As Figures 10 - 15 shown, one group or more groups of adsorbing members can be provided, and each group of adsorbing members will be described below:

[0065] As Figure 10 and Figure 11 shown, the first group of adsorbing members includes a first magnet 191 and a second magnet 192. The first magnet 191 is disposed on the first baffle 111. The second magnet 192 is disposed on the second baffle 112; in the second state, the first baffle 111 and the second baffle 112 partially overlap, and the first magnet 191 can adsorb with the second magnet 192, so as to play a role in fixedly connecting the first baffle 111 and the second baffle 112.

[0066] As Figure 12 and Figure 13Shown is the second set of attracting components, including a third magnet 193 and a fourth magnet 194. The third magnet 193 is disposed on the first baffle 111. The fourth magnet 194 is disposed on the box body 10. In some embodiments, the box body 10 is provided with a first protruding portion 101 at the position of the second opening 14, and the fourth magnet 194 can be disposed on the first protruding portion 101. In the second state, the first baffle 111 rotates to a position where it blocks a part of the second opening 14, and the third magnet 193 on the first baffle 111 adsorbs to the fourth magnet 194 on the first protruding portion 101, thereby stabilizing the relative positional relationship between the movable member 11 and the box body 10 in the second state.

[0067] As Figure 14 and Figure 15 Shown is the third set of attracting components, including a fifth magnet 195 and a sixth magnet 196. The fifth magnet 195 is disposed on the second baffle 112, and the sixth magnet 196 is disposed on the box body 10. In some embodiments, the box body 10 is provided with a second protruding portion 102 at the position of the third opening 15, and the sixth magnet 196 can be disposed on the second protruding portion 102. In the first state, the second baffle 112 is located at a position where it blocks a part of the third opening 15, and the fifth magnet 195 on the second baffle 112 adsorbs to the sixth magnet 196 on the second protruding portion 102, thereby stabilizing the relative positional relationship between the second baffle 112 and the box body 10 in the first state.

[0068] As Figure 16 As shown, an embodiment of the present invention further provides a control method for a household device as described in the above embodiment. The method includes:

[0069] S1. Receive a start instruction, where the start instruction includes a start drying instruction and a start dehumidification instruction; it should be noted that the start instruction can be obtained through an interface for interacting with the user. For example, the user can input an instruction to dry clothes or an instruction to dehumidify the ambient air on the interaction interface on the surface of the housing of the laundry treatment device.

[0070] S2. Receive the current connection state of the switch device, where the current connection state includes a drying state and a dehumidifying state; among them, the dehumidifying state can be used to represent the first state described in the above embodiments, and the drying state can be used to represent the second state described in the above embodiments. In the first state, the first opening is connected to the second opening and blocked from connecting to the third opening; in the second state, the first opening is connected to the third opening. That is to say, in the first state, the first baffle divides the cavity into a first sub-cavity and a second sub-cavity. The first sub-cavity is connected to the second opening and the third opening, the second sub-cavity is connected to the first opening and the second opening, the first opening and the third opening are blocked by the first baffle, and a part of the third opening located in the second sub-cavity is closed by the second baffle. In the current state, the fifth magnet on the second baffle is adsorbed to the sixth magnet on the box body. In the second state, the first baffle rotates to the position where the first magnet is adsorbed to the second magnet, and the second baffle rotates to the position where the second magnet and the third magnet are adsorbed.

[0071] S3. If it is determined that the start instruction does not match the current connection state of the switch device, then change the current connection state of the switch device and start the household device; among them, the drying state corresponds to the drying instruction, and the dehumidifying state corresponds to the dehumidifying instruction. If the dehumidifying state does not correspond to the start dehumidifying instruction, an alarm signal can be sent to prompt an operation error, and the connection state in the dryer can be switched to the dehumidifying state; or if the drying state does not correspond to the start drying instruction, an alarm signal can be sent to indicate an operation error, and the connection state in the dryer can be switched to the drying state. For example, when the received start instruction is an instruction to dehumidify the ambient air, but an induction signal is detected between the third magnet and the fourth magnet, it means that the first baffle is in the position of the second state (that is, the position of the drying state), that is, the start dehumidifying instruction does not correspond to the first state, then the current connection state of the switch device can be adjusted to the dehumidifying state. Another example is when the received start instruction is a drying instruction, but an induction signal is detected between the fifth magnet and the sixth magnet, it means that the second baffle is in the position of the first state (that is, the position of the dehumidifying state), that is, the start drying instruction does not correspond to the second state, then the current connection state of the switch device can be adjusted to the drying state.

[0072] In the embodiment of the present invention, the induction between the second magnet and the third magnet is used to detect whether the start instruction corresponds to the second state, and the induction between the fourth magnet and the fifth magnet is used to detect whether the start instruction corresponds to the first state. The operation is simple and the control is convenient, which is beneficial to improving the operation safety of household devices and reducing the probability of misoperation.

[0073] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
