DETAILED DESCRIPTION

The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and are therefore only used as examples, and the protection scope of the present application cannot be limited by this. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0032] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like 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, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and may be direct contact or contact through an intermediate medium layer. It may be contact with essentially no interaction force between the two contacting parties, or it may be contact with interaction force between the two contacting parties.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In a first aspect, an embodiment of the present application provides a clothing processing device, comprising a motor and a timer of any embodiment of the present application.

[0036] The type of clothing processing equipment is not limited. For example, it can be an agitator washing machine, a pulsator washing machine, a washer-dryer or a twin-tub washing machine, etc. For example, taking a pulsator washing machine as an example, the rotating shaft of the motor is connected to the pulsator, and the rotation of the motor drives the pulsator to rotate, thereby performing the washing function.

[0037] The clothes processing device generally has multiple washing programs, such as strong washing and standard washing, which can be selected based on the washing needs of the user. It is understandable that the speed of the motor in the strong washing program is greater than the speed of the motor in the standard washing program. The motor can rotate forward or reverse in the strong washing program, and the motor can also rotate forward or reverse in the standard washing program.

[0038] The motor is electrically connected to the timer, and the operation of the motor can be controlled by the timer.

[0039] See also Figure 1 and Figure 2 In a second aspect, an embodiment of the present application provides a timer, including a housing 11, an arc extinguishing circuit 12 and a plurality of control circuits.

[0040] The housing 11 has a receiving cavity 11a. The specific structure of the housing 11 is not limited. For example, Figure 1 As shown, the housing 11 includes a first shell 111 and a second shell (not shown), and the first shell 111 and the second shell are arranged opposite to each other, so as to define a receiving cavity 11 a therebetween.

[0041] The accommodating chamber 11a is used to install most of the components of the timer 10 except the housing 11. The first housing 111 and the second housing are detachably connected, so that the components installed in the accommodating chamber 11a can be inspected and repaired, which is beneficial to improving the service life of the timer 10.

[0042] Each control loop corresponds to a different control signal, and each control loop is selectively connected to a power source to output the control signal corresponding to the control loop.

[0043] The number of control loops can be designed based on the operation requirements of the motor. For example, when the clothes processing device has the strong wash program and the standard wash program as mentioned above, the motor may have strong wash forward rotation, strong wash reverse rotation, standard wash forward rotation, and standard wash reverse rotation. Therefore, the number of control loops can be four, and the four control loops correspond to the four operation conditions of the motor one by one, so as to realize the switching of the motor between the four operation conditions.

[0044] The switching of the motor between various operating conditions can be achieved through an external conversion switch, and the conversion switch can selectively turn on one of the multiple control loops to achieve the switching of the motor between different operating conditions.

[0045] Both ends of the control loop have contacts. When the two contacts are connected to the two ends of the power supply respectively, it means that the control loop is in the on state. When one of the contacts is disconnected from the power supply, it means that the control loop is in the off state.

[0046] The arc extinguishing circuit 12 is electrically connected to each control circuit, and is used to extinguish the arc when each control circuit is switched between on and off; each control circuit and the arc extinguishing circuit 12 are arranged in the accommodating cavity 11a.

[0047] In the related technology, an arc is generated at the contact when the contact and the power supply switch from on to off and from off to on. Under the influence of the arc, the contact burns out or fails, thereby shortening the service life of the timer. At the same time, in the process of generating the arc, electromagnetic radiation is also generated to the outside, interfering with other equipment, resulting in relatively poor electromagnetic compatibility of the timer.

[0048] In the timer 10 of the embodiment of the present application, each control circuit is provided with an arc extinguishing circuit 12 electrically connected thereto. When the multiple control circuits are switched between the on state and the off state, the arc can be extinguished by the arc extinguishing circuit 12, and the arc extinguishing circuit 12 is located in the accommodating cavity 11a, that is, the distance between the arc extinguishing circuit 12 and each control circuit is shortened, the arc extinguishing circuit 12 is more sensitive and the arc extinguishing effect is better, thereby helping to improve the electromagnetic compatibility and service life of the timer 10. In addition, the arc extinguishing circuit 12 is integrated in the accommodating cavity 11a of the timer 10, which helps to improve the integration of the timer 10.

[0049] The specific structure of the arc extinguishing circuit 12 is not limited. Figure 1 and Figure 2 In some embodiments, a resistor 121 and a capacitor 122 are provided in series on the arc extinguishing circuit 12, and each control circuit is provided with an arc extinguishing circuit 12 in parallel. That is to say, the arc extinguishing circuit 12 is a resistor-capacitor series circuit, and the contacts on the control circuit will generate an arc at the moment of connection or disconnection. The capacitor 122 can absorb the energy accumulated at both ends of the contacts, and the voltage at both ends of the capacitor 122 is released through the resistor 121, so that the arc generated by the connection or disconnection of the contacts can be eliminated, and then the influence of the arc interference signal can be effectively eliminated, which is conducive to meeting the requirements of the electromagnetic compatibility of the whole machine for the clothing processing equipment, and at the same time, it is conducive to improving the service life of the timer 10.

[0050] The specifications and models of the capacitor 122 and the resistor 121 can be selected according to actual conditions.

[0051] In some other embodiments, the arc extinguishing circuit 12 may also include only the capacitor 122 to form a capacitive arc extinguishing circuit. Alternatively, in addition to the capacitor 122 and the resistor 121, a diode may be connected in series on the arc extinguishing circuit 12 to form a DRC circuit. The principle is to connect a diode, a capacitor 122 and a resistor 121 in parallel on the contact. When the contact is disconnected, the capacitor 122 will form a short circuit, and the diode will limit the current, thereby eliminating the arc.

[0052] See also Figure 1 and Figure 2 In one embodiment, the timer 10 includes a main reed switch 13 and a plurality of branch reed switches 14 electrically connected to the main reed switch 13 , a control circuit is formed between the main reed switch 13 and any branch reed switch 14 , and one end of the arc extinguishing circuit 12 is electrically connected to the main reed switch 13 .

[0053] The contacts on the main reed switch 13 can control the on and off of all control circuits. That is to say, when any control circuit is in the on state, the contacts on the main reed switch 13 need to be connected. When the contacts on the main reed switch 13 are connected, and the contacts on one of the branch reed switches 14 are also connected, the control circuit formed between the branch reed switch 14 and the main reed switch 13 is in the on state; when the contacts on the main reed switch 13 are disconnected, all control circuits are in the off state.

[0054] The on and off of one end of each control circuit is controlled by the main reed switch 13, that is, the contact at one end of each control circuit can be integrated into one contact on the main reed switch 13, thereby reducing the total number of contacts of the timer 10. During the switching process of each control circuit, the contacts on the main reed switch 13 can be maintained in the current state without generating a state change, thereby reducing the number of times an arc is generated.

[0055] In addition, the on and off of all control circuits are controlled by the main reed switch 13, which simplifies the control method of the timer 10, makes the structure of the timer 10 simpler, and increases the degree of integration; and, the arc extinguishing circuit 12 only needs to be electrically connected to the main reed switch 13, thereby simplifying the connection method of the arc extinguishing circuit 12, which is beneficial to improving the assembly efficiency of the timer 10.

[0056] See also Figure 1 and Figure 2 In one embodiment, at least some of the reed switches 14 are electrically connected to each other, and the other end of the arc extinguishing circuit 12 is electrically connected to at least one of the some of the reed switches 14 that are electrically connected to each other.

[0057] For example, Figure 1 As shown, the number of the reed switches 14 is four, and every two of the four reed switches 14 form a group. The reed switches 14 in each group are electrically connected together, and one end of the arc extinguishing circuit 12 is electrically connected to the main reed switch 13, and the other end is electrically connected to a reed switch 14 in each group. This is conducive to further simplifying the connection method of the arc extinguishing circuit 12, thereby improving the assembly efficiency of the timer 10.

[0058] See also Figure 1 and Figure 2In one embodiment, the control signal includes controlling the clothing processing equipment to execute standard washing motor forward rotation and standard washing motor reverse rotation, the arc extinguishing circuit 12 includes a first arc extinguishing circuit 15 with one end electrically connected to the main reed switch 13, the branch reed switch 14 includes a first reed switch 141 corresponding to the standard washing motor forward rotation and a second reed switch 142 corresponding to the standard washing motor reverse rotation, the first reed switch 141 and the second reed switch 142 are electrically connected and both are electrically connected to the other end of the first arc extinguishing circuit 15.

[0059] The first arc extinguishing circuit 15 is connected in series with a resistor 121 and a capacitor 122 .

[0060] It can be understood that, based on the motor, the standard forward washing and standard reverse washing differ only in the direction of rotation of the motor, and the performance parameters of the motor such as power, current, and speed are basically the same. Therefore, when the control circuit that controls the standard forward washing and the control circuit that controls the standard reverse washing are switched between the on state and the off state, the size of the arc generated by the two is basically the same. Furthermore, the same arc extinguishing circuit 12 can be used for arc extinguishing between the two.

[0061] That is to say, the first arc extinguishing circuit 15 can be used to extinguish the arc of the control circuit for controlling the forward rotation of the standard washing and the control circuit for controlling the reverse rotation of the standard washing, which is beneficial to reduce the number of arc extinguishing circuits 12, save the number of electrical components such as capacitors 122 and resistors 121, and thus effectively control the production cost of the timer 10.

[0062] See also Figure 1 and Figure 2 In one embodiment, the control signal also includes controlling the clothing processing equipment to execute forward rotation of the strong washing motor and reverse rotation of the strong washing motor. The arc extinguishing circuit 12 includes a second arc extinguishing circuit 16 having one end electrically connected to the main reed switch 13. The branch reed switch 14 also includes a third reed switch 143 corresponding to the forward rotation of the strong washing motor and a fourth reed switch 144 corresponding to the reverse rotation of the strong washing motor. The third reed switch 143 and the fourth reed switch 144 are electrically connected and both are electrically connected to the other end of the second arc extinguishing circuit 16.

[0063] The second arc extinguishing circuit 16 is also connected in series with a resistor 121 and a capacitor 122 .

[0064] It can be understood that, based on the motor, the difference between forced forward washing and forced reverse washing is only the rotation direction of the motor, and the performance parameters of the motor such as power, current, and speed are basically the same. Therefore, when the control circuit for controlling forced forward washing and the control circuit for controlling forced reverse washing are switched between the on state and the off state, the size of the arc generated by the two is basically the same. Furthermore, the same arc extinguishing circuit 12 can be used for arc extinguishing between the two.

[0065] That is to say, the second arc extinguishing circuit 16 can be used to extinguish the arc of the control circuit that controls the forward rotation of the forced washing and the control circuit that controls the reverse rotation of the forced washing, which is beneficial to reduce the number of arc extinguishing circuits 12, save the number of electrical components such as capacitors 122 and resistors 121, and thus effectively control the production cost of the timer 10.

[0066] See also Figure 1 and Figure 2 In one embodiment, the main reed switch 13 and each branch reed switch 14 are spaced apart along the first direction, so that the main reed switch 13 and each branch reed switch 14 have a certain spacing along the first direction, and the spacing can facilitate the layout of the first arc extinguishing circuit 15 and the second arc extinguishing circuit 16.

[0067] The specific direction of the first direction is not limited. For example, the first direction is Figure 1 and Figure 2 The direction shown by D1.

[0068] The first reed switch 141 , the second reed switch 142 , the third reed switch 143 and the fourth reed switch 144 are arranged along the second direction, and the first direction intersects the second direction.

[0069] Exemplarily, the second direction is Figure 1 The second direction may be orthogonal to the first direction or may form an angle with other angles.

[0070] In this embodiment, the first reed switch 141 is adjacent to the second reed switch 142, the third reed switch 143 is adjacent to the fourth reed switch 144, the first arc extinguishing circuit 15 and the second arc extinguishing circuit 16 can also be arranged in the second direction, and the first arc extinguishing circuit 15 and the second arc extinguishing circuit 16 do not need to be cross-wired, so that one end of the first arc extinguishing circuit 15 can be electrically connected to the first reed switch 141 or the second reed switch 142, and one end of the second arc extinguishing circuit 16 can be electrically connected to the third reed switch 143 or the fourth reed switch 144. As a result, the timer 10 is more convenient to operate during the assembly process.

[0071] See also Figure 1 and Figure 2 In one embodiment, a welding structure is formed between the first arc extinguishing circuit 15 and the first reed switch 141 or the second reed switch 142 .

[0072] That is, the first arc extinguishing circuit 15 is electrically connected to the first reed switch 141 or the second reed switch 142 by welding. The electrical connection structure formed by welding between the first arc extinguishing circuit 15 and the first reed switch 141 or the second reed switch 142 is more reliable, which is conducive to improving the reliability of the timer 10.

[0073] Of course, the first arc extinguishing circuit 15 and the first reed switch 141 or the second reed switch 142 may also be electrically connected by twisting connection, pressing connection, wire crimping connection, or the like.

[0074] See also Figure 1 and Figure 2 In one embodiment, a welding structure is formed between the second arc extinguishing circuit 16 and the third reed switch 143 or the fourth reed switch 144 .

[0075] That is, the second arc extinguishing circuit 16 is electrically connected to the third reed switch 143 or the fourth reed switch 144 by welding. The electrical connection structure formed by welding between the second arc extinguishing circuit 16 and the third reed switch 143 or the fourth reed switch 144 is more reliable, which is conducive to improving the reliability of the timer 10.

[0076] Of course, the second arc extinguishing circuit 16 and the third reed switch 143 or the fourth reed switch 144 can also be electrically connected by twisting connection, pressing connection, wire crimping connection, etc.

[0077] See also Figure 1 and Figure 2 In one embodiment, the timer 10 includes a main conductor 17, the main conductor 17 is welded to the main reed switch 13, the first arc extinguishing circuit 15 includes a first conductor 151, the second arc extinguishing circuit 16 includes a second conductor 161, and the first conductor 151 and the second conductor 161 are respectively connected to the main conductor 17.

[0078] It should be noted that the main conductor 17 and the first conductor 151 can be an integrated structure, that is, the main conductor 17 is a part of the first arc extinguishing circuit 15, and after one end of the first arc extinguishing circuit 15 is electrically connected to the main reed switch 13 by a welding structure, the second conductor 161 is connected to the first arc extinguishing circuit 15; the main conductor 17 can also be an integrated structure with the second conductor 161, that is, the main conductor 17 is a part of the second arc extinguishing circuit 16, and after one end of the second arc extinguishing circuit 16 is electrically connected to the main reed switch 13 by a welding structure, the first conductor 151 is connected to the second arc extinguishing circuit 16; of course, the main conductor 17 can also be an independent part, which belongs neither to the first arc extinguishing circuit 15 nor to the second arc extinguishing circuit 16. After the main conductor 17 is electrically connected to the main reed switch 13 by a welding structure, the first conductor 151 and the second conductor 161 are respectively connected to the main conductor 17.

[0079] In this embodiment, there is only one welding structure between the main conductor 17 and the main reed switch 13, that is, the first arc extinguishing circuit 15 and the second arc extinguishing circuit 16 do not need to be welded to the main reed switch 13 respectively, thereby simplifying the assembly steps of the timer 10 and helping to improve the production efficiency of the timer 10.
