Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and in particular relates to a washing and drying integrated timing device and a double-tub washing machine. Background Art

[0002] A twin-tub washing machine, also known as a twin-cylinder washing machine, generally includes a washing tub and a dehydrating tub that are independent of each other. When in use, the laundry is first placed in the washing tub, and water is poured into the washing tub. The impeller at the bottom of the washing tub rotates, forming a vortex in the washing tub to drive the laundry to rotate and tumble in the washing tub, thereby removing dirt from the laundry. The washed laundry is manually transferred to the dehydrating tub by the user, and the high-speed rotation of the dehydrating tub generates centrifugal force to remove moisture from the laundry. The user can also use the dehydration function alone to dehydrate hand-washed laundry.

[0003] In existing twin-tub washing machines, the operation panel is mostly provided with three knobs, namely, a washing timer for controlling the washing time, an intensity regulator for controlling the washing force, and a dehydration timer for controlling the dehydration time, resulting in an operation interface that is not concise enough. As the user group of washing machines continues to grow, users' personalized needs are becoming increasingly strong. Simplifying the operation interface of twin-tub washing machines so that users can operate the washing machines more intuitively has become one of the goals pursued by various washing machine designers.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing and drying integrated timing device and a double-tub washing machine, which integrate the washing timing function and the dehydration timing function into the washing and drying integrated timer for control, simplifying the operating interface of the double-tub washing machine and facilitating users to operate more intuitively.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A washing and drying integrated timing device comprises a washing motor and a dehydration motor connected in parallel to a control circuit, and also comprises a washing and drying integrated timer, wherein the washing and drying integrated timer comprises:

[0008] A travel mechanism, including a travel cam, for controlling whether the control circuit is powered on;

[0009] A washing timing mechanism, comprising a reversing cam, drivingly connected to the timing cam, and used to control the on and off of the branch where the washing motor is located;

[0010] The dehydration timing mechanism comprises a dehydration cam which is drivingly connected with the timing cam and is used for controlling the on and off of the branch where the dehydration motor is located.

[0011] Further, the control circuit includes a main circuit for connecting to a power source, and a first branch circuit and a second branch circuit respectively connected to the main circuit;

[0012] The travel mechanism also includes a main contact connected in series in the main circuit, and the travel cam controls the connection and disconnection of the main contact through the travel lever;

[0013] The washing motor is connected in series to the first branch; the washing timing mechanism further comprises a reversing contact connected in series to the first branch, and the reversing cam controls the connection and disconnection of the reversing contact through a reversing lever;

[0014] The dehydration motor is connected in series in the second branch; the dehydration timing mechanism also includes a dehydration contact connected in series in the second branch, and the dehydration cam controls the connection and disconnection of the dehydration contact through a dehydration lever.

[0015] Furthermore, the travel cam rotates within a first angle range, and the travel lever controls the main contact to be turned on; the reversing cam controls the reversing contact to be turned on through the reversing lever under the transmission of the travel cam; and the dehydration cam controls the dehydration contact to be turned off through the dehydration lever under the transmission of the travel cam;

[0016] The traveling cam rotates within a second angle range interlaced with the first angle range, and controls the main contact to be connected through the traveling lever; the reversing cam controls the reversing contact to be disconnected through the reversing lever under the transmission of the traveling cam; the dehydration cam controls the dehydration contact to be connected through the dehydration lever under the transmission of the traveling cam.

[0017] Furthermore, the rotatable range of the running cam is from the starting position of the first angle range to the ending position of the second angle range, and there is a certain interval angle between the ending position of the first angle range and the starting position of the second angle range;

[0018] When the travel cam rotates within the interval angle, the main contact is disconnected by controlling the travel lever.

[0019] Furthermore, the elution integrated timer further comprises a running reed and a main static reed, and the main contacts are respectively arranged on the opposite surfaces of the running reed and the main static reed;

[0020] A standby groove is arranged on the traveling cam; when the traveling cam rotates within the interval angle, the part of the traveling lever abutting against the traveling cam enters the standby groove, the traveling lever is separated from the traveling reed, and the main contact is disconnected.

[0021] Furthermore, when the travel cam rotates within a preset angle range, the travel lever controls the main contact to be turned on; the reversing cam controls the reversing contact to be turned on through the reversing lever under the transmission of the travel cam; and the dehydration cam controls the dehydration contact to be turned on through the dehydration lever under the transmission of the travel cam;

[0022] The control circuit is also provided with a switch component for controlling the on and off of the first branch and the second branch.

[0023] Furthermore, the switch assembly comprises:

[0024] A first switch, connected in series to the first branch, and controlling the on and off of the first branch together with the reversing contact;

[0025] The second switch is connected in series to the second branch, and controls the on and off of the second branch together with the dehydration contact.

[0026] Furthermore, it also includes an operating unit for allowing a user to manually operate to control the working state of the switch assembly.

[0027] Furthermore, the travel cam can also rotate within a soaking angle range, and the soaking angle range is connected to the preset angle range; during the timing process, the travel cam rotates from the soaking angle range to the preset angle range;

[0028] When the travel cam rotates within the immersion angle range, the main contact is disconnected by controlling the travel lever.

[0029] A double-tub washing machine comprises a washing unit and a dehydration unit, and also comprises the above-mentioned integrated washing and dehydration timing device; wherein the washing motor is used to drive the washing unit to operate, and the dehydration motor is used to drive the dehydration unit to operate.

[0030] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0031] In the present invention, the washing timing function and the dehydration timing function of the twin-tub washing machine are integrated, and the timing functions of the washing program and the dehydration program can be simultaneously realized through the integrated washing and dehydration timer, thereby replacing the original washing timer and dehydration timer that are separately set, and the number of knob components on the operation panel of the twin-tub washing machine can be reduced. On the one hand, the operation interface is simplified, which is convenient for users to operate more intuitively, and on the other hand, the cost is reduced.

[0032] In the present invention, the washing and drying integrated timer is set to rotate within different angle ranges when the timing cam rotates, and the branch where the washing motor and the dehydration motor are located can be selectively connected, so that the double-barrel washing machine can selectively run the washing program and the dehydration program. The user can complete the complete process of washing first and then dehydrating by performing a timing operation once, which is more convenient. By setting the interval angle that can control the disconnection of the main contact, when the timing cam passes through the interval angle, the double-barrel washing machine is in a non-operating standby state, and then after the washing program is completed, time is reserved for the user to transfer the clothes to the dehydration barrel, ensuring that the user puts the clothes into the dehydration barrel before starting to dehydrate.

[0033] In the present invention, when the washing and drying integrated timer is set to rotate the time cam within the same preset angle range, the reversing contact connected in series with the washing motor and the dehydration contact connected in series with the dehydration motor can be connected at the same time. With the above structure, the user can rotate the washing and drying integrated timer within the same angle range to perform timing, and at the same time, the user can select whether to perform washing timing or dehydration timing by controlling the working state of the switch component, which is more intuitive. In addition, the washing time and the dehydration time can be set independently, and the operation is more flexible.

[0034] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Embodiments of the present invention provide a washing-drying integrated timing device applied to a twin-tub washing machine, and a twin-tub washing machine having the washing-drying integrated timing device.

[0046] Specifically, the twin-tub washing machine includes a washing unit and a dehydrating unit, wherein the washing unit has a washing motor that drives the washing program, and the dehydrating unit has a dehydrating motor that drives the dehydrating program.

[0047] More specifically, the twin-tub washing machine comprises a housing, and a door body that flips upward is installed on the top of the housing. The washing unit comprises a washing tub, and the dehydration unit comprises a dehydration tub. The housing has two chambers that are independent of each other and arranged side by side, one of which serves as a washing tub, and the other chamber is provided with a rotatable dehydration tub. A rotatable impeller is arranged at the bottom of the washing tub, and the washing motor is connected to the impeller, and drives the impeller to rotate when the washing program is running to wash the clothes. The dehydration tub is connected to the dehydration motor, and when the dehydration program is running, the dehydration motor drives the dehydration tub to rotate at a high speed to spin dry the clothes in the tub.

[0048] In the above-mentioned double-barrel washing machine, the washing motor and the dehydrating motor are connected in parallel to the control circuit, and are connected to the power supply respectively. In order to realize the timing of the washing program and the dehydrating program, it is necessary to control the timed power off of the washing motor and the dehydrating motor through a timer. Since the operation of the washing motor and the dehydrating motor is independent of each other, the timed power off of the two motors also needs to be controlled independently. The prior art adopts the method of setting the washing timer and the dehydrating timer separately, which requires two knob assemblies to achieve this, resulting in the operation panel of the double-barrel washing machine not being concise enough, and users may also be confused when using it.

[0049] Embodiment 1

[0050] like Figure 1 and Figure 3 As shown, this embodiment provides a twin-tub washing machine and an integrated washing and drying timing device applied to the twin-tub washing machine, and the washing timing function and the dehydration timing function of the twin-tub washing machine can be realized through a knob assembly.

[0051] Specifically, the whole machine wiring diagram of the double-tub washing machine in this embodiment is as follows: Figure 3 As shown, the washing motor 2 and the dehydrating motor 3 are connected in parallel to the control circuit of the double-tub washing machine, so as to be independently connected to the power supply. More specifically, the control circuit includes a main circuit 10, and a first branch circuit 11 and a second branch circuit 12 respectively connected to the main circuit 10. The washing motor 2 is arranged on the first branch circuit 11, and the dehydrating motor 3 is arranged on the second branch circuit 12.

[0052] The washing and drying integrated timing device described in this embodiment includes the washing motor 2 and the dehydration motor 3 mentioned above, and also includes a washing and drying integrated timer 1. The washing and drying integrated timer 1 has a timing function, which can control the on and off of the main circuit 10 at a timing, thereby realizing the control of whether the control circuit is powered on, and can also control the on and off of the first branch circuit 11 and the second branch circuit 12 respectively, thereby realizing the washing timing function and the dehydration timing function.

[0053] In the specific scheme of this embodiment, the washing and washing integrated timer 1 at least includes a travel mechanism, a washing timing mechanism and a dehydration timing mechanism. Among them, the travel mechanism includes a travel cam. After the timing is turned on, the travel cam can automatically and slowly rotate to reset to the initial position. By rotating the travel cam to different angles, it is possible to control whether the control circuit is powered on. The washing timing mechanism includes a reversing cam, which is connected to the travel cam in a transmission manner. During the rotation and reset of the travel cam, the reversing cam can be driven to rotate, and then the first branch 11 where the washing motor 2 is located can be controlled by the rotation of the reversing cam. Similarly, the dehydration timing mechanism includes a dehydration cam, which is connected to the travel cam in a transmission manner. During the rotation and reset of the travel cam, the dehydration cam can be driven to rotate, and then the second branch 12 where the dehydration motor 3 is located can be controlled by the rotation of the dehydration cam.

[0054] In the above scheme, the washing timing function and the dehydration timing function of the twin-tub washing machine are integrated. The timing functions of the washing program and the dehydration program can be realized simultaneously through the integrated washing and dehydration timer 1, thereby replacing the washing timer and dehydration timer respectively set in the traditional structure. The number of knob components on the operating panel of the twin-tub washing machine can be reduced. On the one hand, the operating interface is simplified, which is convenient for users to operate more intuitively, and on the other hand, the cost is reduced.

[0055] In a further solution of this embodiment, the travel mechanism also includes a main contact connected in series in the main circuit 10, and the travel cam controls the connection and disconnection of the main contact through the travel lever, thereby realizing the control of whether the main circuit 10 is turned on and whether the control circuit is energized.

[0056] The washing timing mechanism also includes a reversing contact connected in series in the first branch 11. The reversing cam controls the connection and disconnection of the reversing contact through a reversing lever, thereby controlling whether the first branch 11 is turned on and whether the washing motor 2 is running.

[0057] The dehydration timing mechanism also includes a dehydration contact connected in series in the second branch 12. The dehydration cam controls the connection and disconnection of the dehydration contact through the dehydration lever, thereby controlling whether the second branch 12 is turned on and whether the dehydration motor 3 is running.

[0058] Specifically, the control circuit further comprises a power plug, and the power plug has an E end for grounding. The L end of the power plug is connected to a fuse 5 arranged on the main circuit 10, and the other end of the fuse 5 is connected to the main interface of the washing and drying integrated timer 1. The washing and drying integrated timer 1 also has two interfaces connected to the washing motor 2 and an interface connected to the dehydration motor 3, and the output lines of the washing motor 2 and the dehydration motor 3 are respectively connected to the N end of the power plug.

[0059] The second branch 12 is also provided with a door switch 4, which is a break position switch. When the dehydration program is running, once the door of the double-tub washing machine is opened, the door switch 4 is disconnected, thereby disconnecting the second branch 12, stopping the dehydration motor 3, and gradually stopping the rotation of the dehydration barrel, thereby ensuring the safety of the user.

[0060] With the above scheme, when the twin-tub washing machine runs the washing program, the main contact in the timing mechanism remains connected, and the reversing contact in the washing timing mechanism is connected to drive the washing motor 2 to rotate alternately forward and reverse, so as to realize the forward and reverse rotation of the impeller in the washing tub, and wash the clothes in the tub. When the twin-tub washing machine runs the dehydration program, the main contact in the timing mechanism remains connected, and the dehydration contact in the dehydration timing mechanism is connected to drive the dehydration motor 3 to rotate, so as to realize the high-speed rotation of the dehydration tub to dehydrate the clothes. When the twin-tub washing machine is in the standby state, the main contact, the reversing contact and the dehydration contact are all in the disconnected state, and at this time, the washing motor 2 and the dehydration motor 3 are not running.

[0061] In a further solution of this embodiment, the washing and drying timer 1 has a timing shaft, and the timing cam is mounted on the timing shaft. The timing shaft is connected to the knob assembly provided on the operating panel of the double-barrel washing machine, so that the knob assembly, the timing shaft and the timing cam rotate synchronously. When the user rotates the knob assembly, the timing cam can be driven to rotate to a specific angle through the timing shaft. Afterwards, when the user releases the knob assembly, the timing cam can be slowly reset at a fixed speed driven by the mechanical structure inside the washing and drying timer 1, and the reversing cam and the dehydration cam can be driven to rotate during the rotation process, so as to control whether the reversing contacts and the dehydration contacts are connected, and whether the washing motor 2 and the dehydration motor 3 are working, thereby realizing the corresponding timing function.

[0062] Specifically, in this embodiment, the rotation area of ​​the elution integrated timer 1 is shown as follows: Figure 1 As shown, it includes a washing area covering a first angle range α, and a dehydration area covering a second angle range β, wherein the washing area and the dehydration area are alternately arranged.

[0063] When the travel cam rotates within the first angle range α, the travel lever can control the main contact to be turned on, thereby controlling the main circuit 10 of the circuit to be turned on. During this period, the reversing cam controls the reversing contact to be turned on through the reversing lever under the transmission of the travel cam, thereby causing the washing motor 2 to rotate alternately forward and reverse. At the same time, the dehydration cam controls the dehydration contact to be turned off through the dehydration lever under the transmission of the travel cam, thereby keeping the dehydration motor 3 in the off state. In this way, when the travel cam is within the first angle range α, the double-tub washing machine can run the washing program.

[0064] When the travel cam rotates within the second angle range β, the travel lever can also control the main contact to be turned on, thereby controlling the main circuit 10 of the circuit to be turned on. During this period, the reversing cam controls the reversing contact to be turned off through the reversing lever under the transmission of the travel cam, so that the washing motor 2 remains in the off state. At the same time, the dehydration cam controls the dehydration contact to be turned on through the dehydration lever under the transmission of the travel cam, so that the dehydration motor 3 is in the working state, driving the dehydration barrel to rotate at a high speed. In this way, when the travel cam is within the second angle range β, the double-barrel washing machine can run the dehydration program.

[0065] Furthermore, the initial position of the travel cam is at one end of the second angle range β, that is, Figure 1 The user can rotate the knob assembly clockwise to pass through the dehydration area and enter the washing area, and release the knob assembly at a corresponding angle according to the washing time set as needed, after which the running cam can automatically rotate counterclockwise to reset, gradually leaving the first angle range α corresponding to the washing area, and then entering the second angle range β corresponding to the dehydration area, and finally stop rotating when reaching the position at the bottom of the corresponding dehydration area.

[0066] In this way, the integrated washing and drying timer 1 of this embodiment can complete the timing of the washing program and the dehydration program at one time, without the need for the user to perform the timing operation again in the middle, which is more convenient.

[0067] In the preferred solution of this embodiment, the rotatable range of the running cam when automatically resetting is from the starting position of the first angle range α to the ending position of the second angle range β, and there is a certain interval angle γ between the ending position of the first angle range α and the starting position of the second angle range β.

[0068] The interval angle γ corresponds to the standby area. When the travel cam rotates within the interval angle γ, the main contact is disconnected by controlling the travel lever. At this time, the control circuit is powered off and the twin-tub washing machine does not work.

[0069] Preferably, when the running cam is within the interval angle γ, the reversing cam controls the reversing contact to be disconnected through the reversing lever under the transmission of the running cam, and at the same time, the dehydration cam controls the dehydration contact to be disconnected through the dehydration lever under the transmission of the running cam. In this way, it is ensured that the washing motor 2 and the dehydration motor 3 will not be connected to the power supply and can remain in the off state.

[0070] In the above scheme, after the washing and drying timer 1 passes the washing area, it first enters the standby area, at which time the washing program ends, and the double-tub washing machine remains in the standby state and does not work. In this way, the user does not need to operate the washing and drying timer 1 additionally, that is, the dehydration program will not be run immediately after the washing program ends, thereby reserving time for the user to transfer the clothes to the dehydration barrel after the washing program is completed. After the washing and drying timer 1 passes the standby area, it enters the dehydration area, at which time the dehydration motor 3 starts and starts the dehydration program.

[0071] Specifically, in order to realize the control of the on-off of the main contact by the traveling cam through the traveling lever, the elution timer 1 also includes a traveling reed and a main static reed, both of which are installed on the main contact spring seat, and the main contact spring seat is connected to the main circuit 10, and the main contacts are respectively arranged on the opposite surfaces of the traveling reed and the main static reed.

[0072] One end of the travel lever abuts against the outer periphery of the travel cam, and the travel cam pushes the travel lever away, so that the travel lever pushes the main contact on the travel spring to contact and conduct with the main contact on the main static spring. A groove structure is provided on the travel cam, and when the part of the travel lever abutting against the travel cam enters the groove structure during the rotation of the travel cam, the travel lever separates from the travel spring, and the two main contacts separate and disconnect.

[0073] Furthermore, the groove structure at least includes a standby groove. When the traveling cam rotates within the interval angle γ, the part of the traveling lever abutting against the traveling cam enters the standby groove, so that the traveling lever is separated from the traveling reed, and the two main contacts are separated and disconnected.

[0074] Similarly, when the running cam rotates to the end position of the second angle range β, that is, the lowermost end of the dehydration area, the part of the running lever abutting against the running cam enters another groove, thereby controlling the two main contacts to separate and disconnect again.

[0075] In this embodiment, the washing timing mechanism includes two groups of reversing spring groups, on which reversing contacts are respectively arranged. Two reversing levers are arranged, corresponding to one of the reversing spring groups. When the running cam rotates within the first angle range α, the reversing cam rotates under the transmission action of the running cam, alternately pushing open the two reversing levers, and then controlling the reversing contacts on the two reversing spring groups to be alternately connected, realizing the reversing control of the washing motor 2, so that the washing motor 2 rotates alternately forward and reverse. When the running cam rotates in the area outside the first angle range α, the two reversing levers are separated from the corresponding reversing spring groups, and then the reversing contacts are disconnected.

[0076] The dehydration cam is sleeved on the timing shaft, so that the dehydration cam rotates synchronously with the travel cam. The dehydration timing mechanism also includes a dehydration reed arranged on the main contact spring seat, the dehydration reed and the travel reed are respectively arranged on both sides of the main static reed, and dehydration contacts are respectively arranged on the opposite surfaces of the dehydration reed and the main static reed. When the travel cam rotates within the second angle range β, the travel lever simultaneously pushes the travel reed and the main static reed to approach the direction where the dehydration reed is located, and the dehydration cam rotates under the transmission action of the travel cam, and the position where the groove is arranged on it corresponds to the dehydration lever. At this time, the dehydration lever does not contact the dehydration reed, so that the dehydration contact on the dehydration reed is in contact with the dehydration contact on the main static reed. When the travel cam rotates in an area other than the second angle range β, the dehydration lever is pushed open by the dehydration cam, and then the dehydration reed is pushed, so that the two dehydration contacts are separated and disconnected.

[0077] In a specific implementation of this embodiment, the integrated washing and washing timer 1 can be modified from an existing washing timer. Specifically, the integrated washing and washing timer 1 is provided with an escape wheel and a balance wheel for controlling the rotation speed of the time cam when it is reset. By adjusting the pressure angle of the escape wheel or the weight of the balance wheel, the maximum timing duration of the integrated washing and washing timer 1 can be adjusted.

[0078] Furthermore, some existing washing timers can be connected to a buzzer, and when the washing program is completed or nearly completed, the buzzer is turned on to emit a buzzer reminder. In this embodiment, the original interface for connecting the buzzer can be connected to the dehydration motor 3, that is, the dehydration cam and the dehydration lever are the original buzzer cam and buzzer lever, and by adjusting the size of the groove structure on the dehydration cam, and the relative angle relationship between the groove structure and the timing cam, it can be achieved that after the washing program is completed, the double-tub washing machine stands by for a period of time, and then the dehydration motor 3 is turned on to run the dehydration program.

[0079] As a specific solution of this embodiment, the maximum timing duration of the washing and drying integrated timer 1 is set to 25 minutes, including 15 minutes for the washing program, 5 minutes for the dehydration program, and 5 minutes for the standby program. Figure 1 In the rotation area of ​​the washing and drying integrated timer 1, the top end is marked as 0°, and the angle is calculated clockwise, 0° to 180° is the washing area (where 180° corresponds to a washing time of 15 minutes), 300° to 0° is the standby area, and 240° to 300° is the dehydration area (where 300° corresponds to a dehydration time of 5 minutes). The timing duration corresponding to different angle positions is marked on the periphery of the rotation area.

[0080] The initial position of the washing and drying timer 1 corresponds to the 240° position. When the user uses the double-barrel washing machine of this embodiment, if he needs to wash clothes first and then dehydrate, after completing the preparations such as placing clothes and adding water, he can turn the washing and drying timer 1 clockwise to the corresponding angle in the washing area according to the required washing time, and then release the washing and drying timer 1. For example, if the washing time needs to be set to 12 minutes, the washing and drying timer 1 is rotated clockwise from the initial 240° position to the angle position corresponding to 12 minutes. At this time, the main circuit 10 of the control circuit is turned on, and the first branch 11 is turned on, and the second branch 12 is disconnected, so that the washing motor 2 can rotate forward and reverse alternately to run the washing program, and the dehydration motor 3 remains in the off state.

[0081] After the set washing time, the integrated washing and drying timer 1 rotates counterclockwise to the 0° position, at which time the main circuit 10 and the first branch circuit 11 are disconnected at the same time, the washing motor 2 stops running, and the washing program ends. At this time, the second branch circuit 12 remains disconnected, the dehydration motor 3 is also turned off, and the twin-tub washing machine does not work. The integrated washing and drying timer 1 continues to rotate counterclockwise to the 300° position. During this period, the twin-tub washing machine is in standby mode, and the user can transfer the clothes in the washing tub to the dehydration tub and wait for the dehydration program to start.

[0082] After 5 minutes from the end of the washing program, the washing and drying integrated timer 1 rotates to the 300° position, at which time the main circuit 10 is turned on again, and at the same time the second branch circuit 12 is turned on, the dehydration motor 3 is powered on, the dehydration program starts, and the dehydration barrel starts to rotate at a high speed to dehydrate the clothes in the barrel. At this time, the first branch circuit 11 remains disconnected, and the washing motor 2 remains off and does not work.

[0083] After another 5 minutes, the washing and drying integrated timer 1 rotates to the 240° position, at which time the main circuit 10 is disconnected, and the second branch circuit 12 is also disconnected, the dehydration motor 3 is powered off and stops working, and the dehydration barrel gradually stops rotating. The first branch circuit 11 remains disconnected, and the washing motor 2 remains turned off. At this point, the double-barrel washing machine completely stops running.

[0084] In the above scheme, the user turns the knob assembly once to set the timing, and the double-tub washing machine can complete the entire process of washing first and then dehydrating in a timely manner, simplifying the user's operation steps. It is understandable that if the user wants to set the dehydration time to be less than 5 minutes, after completing the transfer of the clothes to the dehydration barrel, the dehydration program can be automatically started without waiting for the washing and drying timer 1 to rotate to the 300° position, but the washing and drying timer 1 can be manually rotated counterclockwise to the angle position corresponding to the required dehydration time, and then the washing and drying timer 1 can be released.

[0085] The user can also use the above-mentioned washing and drying integrated timer 1 to time the dehydration process separately. Specifically, the user puts the clothes to be dehydrated into the dehydration barrel, and then rotates the washing and drying integrated timer 1 clockwise to the corresponding angle position in the dehydration area according to the desired dehydration time. For example, if you want to set the dehydration time to 5 minutes, rotate it clockwise from the 240° position to the 300° position corresponding to 5 minutes; and if you want to set the dehydration time to 3 minutes, rotate it clockwise from the 240° position to the angle position corresponding to 3 minutes.

[0086] When the user rotates the washing and drying integrated timer 1 to the desired position and releases it, the washing and drying integrated timer 1 can automatically rotate counterclockwise to reset. At this time, the main circuit 10 and the second branch circuit 12 of the control circuit are simultaneously connected, and the first branch circuit 11 is disconnected, so the washing motor 2 is turned off and does not work, and the dehydration motor 3 is powered on to start, driving the dehydration barrel to rotate and run the dehydration program.

[0087] When the washing and drying integrated timer 1 rotates to the 240° position, the main circuit 10 and the second branch circuit 12 are disconnected at the same time, the dehydration motor 3 is powered off and stops working, the dehydration barrel gradually stops rotating, and the dehydration program ends. During the entire dehydration process, the first branch circuit 11 remains disconnected and the washing motor 2 remains turned off.

[0088] In this embodiment, the double-tub washing machine is provided with a washing and drying integrated timer 1. A knob assembly is provided on the operation panel to realize the timing functions of the washing program and the dehydration program respectively. The three knob assemblies on the original operation panel can be reduced to two, and the operation panel is more concise. At the same time, the cost is reduced due to the reduction in the number of timer settings. The washing area used for timing the washing program and the dehydration area used for timing the dehydration program on the washing and drying integrated timer 1 do not overlap, and during the timing process, the washing and drying integrated timer 1 can automatically rotate from the washing area to the dehydration area. In this way, the user only needs to perform the timing operation of rotating the knob assembly once to time the entire process of washing first and then dehydrating, and the operation is simple and convenient.

[0089] Embodiment 2

[0090] like Figure 2 and Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment 1 is that the rotation area of ​​the integrated elution timer 1 includes an elution area covering a preset angle range θ. When the user times the washing program and the dehydration program, the integrated elution timer 1 needs to be rotated to a certain position in the elution area.

[0091] By adopting the above solution, when the user operates the double-tub washing machine to run the washing program and the dehydration program, the user can rotate the washing and drying integrated timer 1 in the same rotating area to perform the timing operation, which is more intuitive.

[0092] Specifically, in order to achieve the timing of the washing program and the timing of the dehydration program using the same elution area, this embodiment further adopts the following solution.

[0093] In the washing and drying integrated timer 1, when the travel cam of the travel mechanism rotates within the preset angle range θ, the travel lever can control the main contact to be connected, thereby controlling the main circuit 10 of the circuit to be turned on. During this period, the reversing cam of the washing timing mechanism is driven by the travel cam and the reversing contact is controlled to be turned on by the reversing lever (specifically, the reversing contacts on the two sets of reversing springs are alternately connected). At the same time, the dehydration cam of the dehydration timing mechanism is driven by the travel cam and the dehydration contact is controlled to be turned on by the dehydration lever.

[0094] It is understandable that when a user uses a double-tub washing machine, he often only needs to run a washing program or a dehydration program at the same time. To this end, in this embodiment, a switch component is further provided on the control circuit, and the switch component can further control the on and off of the first branch 11 and the second branch 12.

[0095] For example, when the washing program is running, the switch assembly controls the first branch 11 to be turned on and the second branch 12 to be turned off. At this time, the reversing contact on the first branch 11 is in the on state, and the washing motor 2 can be controlled to be powered on. Although the dehydration contact on the second branch 12 is connected, the second branch 12 is still in the off state, so the dehydration motor 3 is not powered and remains in the off state. In this way, the double-tub washing machine can run the washing program.

[0096] Similarly, when the dehydration program is running, the switch assembly controls the first branch 11 to be disconnected and the second branch 12 to be turned on. In this case, although the reversing contact is turned on, the first branch 11 is in a disconnected state, so that the washing motor 2 is not energized. The second branch 12 is turned on through the switch assembly and the turned-on dehydration contact, so that the dehydration motor 3 is energized, and the double-tub washing machine can run the dehydration program with the dehydration tub rotating at a high speed.

[0097] In a specific solution of this embodiment, the switch assembly includes a first switch 21 and a second switch 22. The first switch 21 is connected in series to the first branch 11, and controls the on-off of the first branch 11 together with the reversing contact. That is, when the first switch 21 is closed and the reversing contact is connected, the first branch 11 can be turned on, otherwise the first branch 11 is in a disconnected state. Similarly, the second switch 22 is connected in series to the second branch 12, and controls the on-off of the second branch 12 together with the dehydration contact. That is, when the second switch 22 is closed and the dehydration contact is connected, the second branch 12 is turned on, otherwise the second branch 12 is in a disconnected state.

[0098] Furthermore, in this embodiment, the working state of the switch assembly, that is, the on and off state of the first switch 21 and the second switch 22, is manually controlled by the user. Specifically, the elution-integrated timer 1 of this embodiment also includes an operating unit, and the user can manually operate the operating unit to control the working state of the switch assembly.

[0099] In detail, the operating part can be set on the operating panel of the twin-tub washing machine, including a first operating part corresponding to the first switch 21, and a second operating part corresponding to the second switch 22. When the user uses the twin-tub washing machine to run the washing program, the first operating part can be operated to close the first switch 21, and the second operating part can be used to control the second switch 22 to be in an open state. At this time, the washing and washing integrated timer 1 is rotated to a certain position in the washing area, and the main circuit 10 and the first branch 11 of the control circuit can be turned on at the same time, and the second branch 12 remains in an open state. At this time, the twin-tub washing machine can run the washing program.

[0100] On the contrary, when the user uses the twin-tub washing machine to run the dehydration program, the user can operate the first operating part to turn off the first switch 21, and operate the second operating part to close the second switch 22, and then rotate the washing and drying integrated timer 1 to a certain position in the washing area. At this time, the main circuit 10 and the second branch circuit 12 of the control circuit are simultaneously connected, and the first branch circuit 11 is in a disconnected state, and the twin-tub washing machine can run the dehydration program.

[0101] In another specific solution of this embodiment, the switch assembly may be a selection switch, and the selection switch selectively conducts the first branch and the second branch. Correspondingly, only one operation unit may be provided, and the user may control the conduction direction of the selection switch by operating the operation unit, thereby conducting one of the first branch and the second branch.

[0102] In this embodiment, the mechanical structure inside the elution-integrated timer 1 is similar to that in the above-mentioned embodiment 1. Since the main contact, the reversing contact and the dehydration contact can be controlled to be in the on state at the same time when the time cam rotates within the preset angle range θ, it is only necessary to adjust the size of the groove structure on the reversing cam and the dehydration cam, and the relative position relationship of the groove structure with respect to the groove on the time cam according to the size of the preset angle range θ.

[0103] In a further embodiment of the present invention, the rotatable area of ​​the elution-integrated timer 1 also includes a range of immersion angles. The immersion area, where the immersion angle range Connected to the preset angle range θ. When the cam is in the immersion angle range When the inner part rotates, the main contact can be disconnected by controlling the travel lever. At this time, the main path 10 of the control circuit is disconnected, that is, the control circuit is not energized and the double-tub washing machine does not run.

[0104] Preferably, when the cam is in the immersion angle range When the inner rotation is performed, the reversing cam is driven by the running cam, and the reversing contact is disconnected through the reversing lever. The dehydration cam is driven by the running cam, and the dehydration contact is disconnected through the dehydration lever.

[0105] Specifically, in this embodiment, the initial position of the running cam is within the preset angle range θ away from the immersion angle range One end of Figure 2 The user can turn the knob assembly of the elution timer 1 clockwise to make it pass through the elution area and then enter the soaking area, and release the elution timer 1 at a certain position in the soaking area. After that, the running cam automatically rotates counterclockwise to reset, passing through the soaking angle range corresponding to the soaking area first. , and then enters the preset angle range θ corresponding to the elution area.

[0106] Since the twin-tub washing machine does not work when the integrated washing and drying timer 1 passes through the soaking area, the user can use the integrated washing and drying timer 1 to perform a timing operation of soaking the clothes first and then starting the washing program at a fixed time.

[0107] Furthermore, in order to realize that when the washing and washing integrated timer 1 rotates to the soaking area, the main circuit 10 of the control circuit is disconnected and the double-tub washing machine does not work, a corresponding soaking groove needs to be added to the timer cam. When the timer cam rotates to the preset angle range θ corresponding to the soaking area, the part of the timer lever abutting against the outer periphery of the timer cam enters the soaking groove, thereby separating from the timer reed, and the timer reed is separated from the main contact on the main static reed.

[0108] As a specific solution of this embodiment, the maximum timing duration of the washing and drying integrated timer 1 is set to 45 minutes, including 15 minutes for the washing program or the dehydration program timing, and 30 minutes for the soaking timing. Figure 2 In the rotation area of ​​the elution timer 1, the top is marked as 0°, and the angle is calculated clockwise. 0°~100° is the elution area (where 100° corresponds to a washing / spinning time of 15 minutes), and 100°~300° is the soaking area (where 300° corresponds to a soaking time of 30 minutes).

[0109] The initial position of the washing and drying integrated timer 1 corresponds to the 0° position. When the user uses the double-barrel washing machine of this embodiment, if the user needs to soak the clothes before washing, after completing the preparations such as placing the clothes and adding water, the user closes the first switch 21 by operating the operating unit, and at the same time, the second switch 22 is in the open state. Then, the washing and drying integrated timer 1 can be rotated clockwise to the corresponding angle in the soaking area according to the required soaking time (such as rotating to the 300° position when the soaking time is 30 minutes). At this time, the main circuit 10, the first branch 11 and the second branch 12 of the control circuit are all in the open state, the washing motor 2 and the dehydration motor 3 are not powered, the double-barrel washing machine does not work, and the clothes are soaked in the washing barrel.

[0110] The user rotates the washing and drying timer 1 to the right position and then releases it, and the washing and drying timer 1 can automatically rotate counterclockwise to reset. After the set soaking time, the washing and drying timer 1 rotates counterclockwise to the 100° position, at which time the main contact, the reversing contact and the dehydration contact are all connected, but because the second switch 22 is in the disconnected state, only the main circuit 10 and the first branch circuit 11 are connected, and the washing motor 2 is energized to drive the washing tub to rotate alternately forward and reverse. The dehydration motor 3 remains in the off state at this time, and the double-tub washing machine can start running the washing program.

[0111] After 15 minutes from the start of the washing program, the washing and drying integrated timer 1 rotates to the 0° position, at which time the main circuit 10 and the first branch circuit 11 are disconnected again, the washing motor 2 is powered off and stops working, and the washing program ends.

[0112] It is understandable that if the user places the clothes and wants to start the washing program directly, after closing the first switch 21 and disconnecting the second switch 22 through the operating unit, the washing and washing integrated timer 1 can be directly rotated clockwise to the corresponding angle position in the washing area according to the required washing time, so that the main path 10 and the first branch 11 are directly connected, and the washing program starts. After the user releases the washing and washing integrated timer 1, after the set washing time, the washing and washing integrated timer 1 can be rotated counterclockwise back to the 0° position, and then the main path 10 and the first branch 11 are disconnected, and the washing program ends.

[0113] If the user needs to spin dry the laundry, the laundry in the washing tub can be transferred to the dehydration tub, and then the first switch 21 is turned off through the operation unit, and the second switch 22 is turned on. Then the washing and drying timer 1 is turned again, and is turned to the corresponding angle position in the washing area according to the desired dehydration time. For example, when the dehydration time is set to 6 minutes, the washing and drying timer 1 is turned from the initial 0° position to the 40° position.

[0114] When the user rotates the washing and drying timer 1 to the desired position and releases it, the washing and drying timer 1 can automatically rotate counterclockwise to reset. At this time, the main contact, the reversing contact and the dehydration contact are all connected, but since the first switch 21 is in the off state, only the main circuit 10 and the second branch circuit 12 are connected, and the dehydration motor 3 is energized to run the dehydration program, driving the dehydration barrel to rotate at a high speed to dehydrate the clothes in the barrel.

[0115] After the set dehydration time, the elution-washing integrated timer 1 rotates counterclockwise to the 0° position, at which time the main path 10 and the second branch path 12 are disconnected, the dehydration motor 3 is powered off and stops working, and the dehydration program ends.

[0116] The operation process when the user uses the twin-tub washing machine to run only the dehydration program is basically the same as the above process, that is, the clothes to be dehydrated are placed in the dehydration barrel, and then the operation part is operated to open the first switch 21 and close the second switch 22, and then the washing and drying integrated timer 1 is turned according to the desired dehydration time to perform the dehydration timing. The twin-tub washing machine can start the dehydration program and end the dehydration program after the set dehydration time.

[0117] In this embodiment, the user can rotate the integrated washing and drying timer 1 within the same angle range for timing, and at the same time, by controlling the working state of the switch assembly, select whether to perform washing timing or dehydration timing, which is more intuitive. In addition, the washing time and dehydration time can be set independently, which can more flexibly match the user's usage needs. The integrated washing and drying timer 1 also provides a function for timing the soaking time before starting the washing program. When the user uses the double-barrel washing machine to wash clothes, the soaking time can be set. The double-barrel washing machine automatically starts the washing program for washing clothes after the set soaking time. No user operation is required in the middle, which is more convenient.

[0118] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
