Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and more specifically, relates to a control device and control method for washing and care equipment. Background Technology

[0002] With the advancement of technology and society, washing and care equipment has become increasingly functional, which in turn requires driving more and more loads. However, due to the limited space on the control board, the number of interfaces is limited, which can lead to situations where insufficient interfaces prevent the driving of too many loads and cause some functions to fail.

[0003] In existing technologies, one switch in a control circuit typically controls one load. In other words, the number of switches needed to control several loads is the same. However, because the size of the control board is limited by the structural space, it cannot be arbitrarily adjusted. This can lead to situations where there is not enough space to add interfaces and switches, thus preventing the addition of new functions.

[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 control device and control method for washing and care equipment. The device and method group loads that do not work at the same time or loads that work at the same time and do not work at the same time, so that one switch in one control loop can control two or more loads. By controlling the switch in the control loop, the effect of individual control of the load can be achieved. This can save control loop components, save space, and control more loads.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A washing and care equipment control device and control method include a control board and a load. The control board is provided with interfaces, including at least a first interface, a second interface, a third interface and a fourth interface.

[0008] The load is divided into a first group of loads and a second group of loads. The first group of loads includes at least the first and second loads, and the second group of loads includes at least the third load.

[0009] The first end of the first load and the first end of the second load are simultaneously electrically connected to the first interface, and the first end of the third load is electrically connected to the fourth interface.

[0010] The second terminals of the first load and the third load are simultaneously electrically connected to the second interface, and the second terminal of the second load is electrically connected to the third interface.

[0011] Furthermore, the second load group includes a fourth load, the first end of which is electrically connected to the fourth interface, and the second end of the fourth load and the second end of the second load are simultaneously electrically connected to the third interface.

[0012] Furthermore, the second load group includes a fifth load, the first end of which is electrically connected to the fourth interface, and the second end of the fifth load is electrically connected to the second end of the first load and the second end of the third load, which are simultaneously electrically connected to the second interface.

[0013] Alternatively, the second terminal of the fifth load, the second terminal of the second load, and the second terminal of the fourth load are simultaneously electrically connected to the third interface;

[0014] Furthermore, the first interface and the fourth interface are simultaneously connected to the common terminal on the control board, and the second interface and the third interface are simultaneously connected to the power control terminal on the control board.

[0015] Furthermore, the second end of the third load is connected to the second end of the first load, the second end of the fourth load is connected to the second end of the second load, and the second end of the fifth load is connected to the second end of the first load, or the second end of the fifth load is connected to the second end of the second load.

[0016] Furthermore, the switch is located between the interface and the common terminal on the control board or the power control terminal on the control board, and one switch corresponds to one interface;

[0017] Furthermore, the switch can use a thyristor or a relay;

[0018] Furthermore, only two interfaces are simultaneously connected to the common terminal on the control board, while the other interfaces are simultaneously connected to the power control terminal on the control board.

[0019] Furthermore, when the first interface and the second interface are powered on, the first load operates; when the first interface and the third interface are powered on, the second load operates; when the first interface, the second interface, and the third interface are powered on, the first load and the second load operate simultaneously; when the second interface and the fourth interface are powered on, the third load operates.

[0020] Furthermore, when the first and second interfaces are powered on, the first load operates; when the first and third interfaces are powered on, the second load operates; when the first, second, and third interfaces are powered on, the first and second loads operate simultaneously; when the second and fourth interfaces are powered on, the third load operates; when the third and fourth interfaces are powered on, the fourth load operates; and when the second, third, and fourth interfaces are powered on, the third and fourth loads operate simultaneously.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0022] 1. By controlling the loads in the washing machine in groups, the number of control loops and switches in the control loops is reduced, as is the number of wires between loads or between loads and the control board. This reduces the pressure on the wiring, making it easier to assemble, disassemble, and repair the washing machine when it malfunctions. It is also low in cost and highly applicable.

[0023] 2. According to the existing control scheme, driving six loads requires seven control loops, while the control scheme of the present invention can drive six loads with only five control loops, reducing the number of control loops and solving the problem of control board size being limited by structural space to a certain extent. On this basis, the control board has enough space to add new control loops to add new loads.

[0024] 3. Loads that are both working and not working at the same time can be grouped in the equipment, so that one control loop can control two or more loads, which increases the scalability of the equipment. That is, under certain conditions, new loads can be added without adding new control loops.

[0025] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In the embodiments of this application, a washing and care equipment control device and control method are provided, specifically, a control device for grouping and controlling the load of a washing machine is provided.

[0036] like Figure 1 The diagram shows the schematic of a control scheme in the prior art. The left side of the diagram is the control board, which includes the power control terminal LoadCTL, the common terminal LoadCOM, switches SW1 to SW7, and interface CN1 on the control board. The right side of the diagram shows the entire load and wiring harness, including six loads Load1 to Load6. Switch SW1 is connected to the common terminal LoadCOM, and switches SW2 to SW7 are connected to the power control terminal LoadCTL. To drive load Load1, switches SW1 and SW2 need to be closed to connect the common terminal LoadCOM to the power control terminal LoadCTL. To drive load Load2, switches SW1 and SW3 need to be closed to connect the common terminal LoadCOM to the power control terminal LoadCTL. Similarly, to drive loads Load3, Load4, Load5, and Load6, switches SW1 and SW4, SW1 and SW5, SW1 and SW6, and SW1 and SW7 need to be closed, respectively.

[0037] The control scheme of this application includes a power control terminal LoadCTL, a common terminal LoadCOM, switches SW1 to SW4 in the control loop, and a first interface, a second interface, a third interface, and a fourth interface on the control board. The load is divided into a first group of loads and a second group of loads. The first group of loads includes at least a first load and a second load, and the second group of loads includes at least a third load. The first end of the first load and the first end of the second load are simultaneously electrically connected to the first interface. The first end of the third load is electrically connected to the fourth interface. The second end of the first load and the second end of the third load are simultaneously electrically connected to the second interface. The second end of the second load is electrically connected to the third interface.

[0038] One end of the interface on the control board is connected to the load, and the other end is connected to the switch in the control loop. One interface on the control board corresponds to one switch. Switches SW1 and SW4 are connected to the common terminal LoadCOM on the control board, and switches SW2 and SW3 are connected to the power control terminal LoadCTL on the control board. The second end of the third load is connected to the second end of the first load. The first load and the third load are controlled by switch SW2 in the same control loop.

[0039] When switches SW1 and SW2 are closed, the power control terminal LoadCTL and the common terminal LoadCOM on the control board are connected, energizing the first and second interfaces and enabling the first load to operate. When switches SW1 and SW3 are closed, the first and third interfaces are energized, enabling the second load to operate. When switches SW2 and SW4 are closed, the second and fourth interfaces are energized, enabling the third load to operate. When switches SW1, SW2, and SW4 are closed simultaneously, the first, second, and fourth interfaces are energized simultaneously, enabling the first and third loads to operate simultaneously. When switches SW1, SW2, and SW3 are closed simultaneously, the first, second, and third interfaces are energized, enabling the first and second loads to operate simultaneously. In this control scheme, the second terminal of the third load and the second terminal of the first load are simultaneously connected to the second interface. Therefore, the third load and the first load can operate simultaneously, but the third load and the second load cannot operate simultaneously.

[0040] In the control scheme of this application, when the first group of loads includes at least a first load and a second load, and the second group of loads includes at least a third load and a fourth load, the first end of the first load and the first end of the second load are simultaneously electrically connected to the first interface, the first end of the third load and the first end of the fourth load are simultaneously electrically connected to the fourth interface, the second end of the first load and the second end of the third load are simultaneously electrically connected to the second interface, and the second end of the second load and the second end of the fourth load are simultaneously electrically connected to the third interface.

[0041] Switches SW1 and SW4 are connected to the common terminal LoadCOM on the control board, and switches SW2 and SW3 are connected to the power control terminal LoadCTL on the control board. The second terminal of the third load is connected to the second terminal of the first load, and the second terminal of the fourth load is connected to the second terminal of the second load. The first and third loads are controlled by switch SW2 in the same control loop, and the second and fourth loads are controlled by switch SW3 in the same control loop.

[0042] When switches SW1 and SW2 are closed, the power control terminal LoadCTL and the common terminal LoadCOM on the control board are connected, energizing the first and second interfaces and enabling the first load to operate. When switches SW1 and SW3 are closed, the first and third interfaces are energized, enabling the second load to operate. When switches SW2 and SW4 are closed, the second and fourth interfaces are energized, enabling the third load to operate. When switches SW3 and SW4 are closed, the third and fourth interfaces are energized, enabling the fourth load to operate. When switches SW1, SW2, and SW3 are closed simultaneously, the first, second, and third interfaces are energized, enabling the first and second loads to operate simultaneously. When switches SW2, SW3, and SW4 are closed simultaneously, the second, third, and fourth interfaces are energized, enabling the third and fourth loads to operate simultaneously. In this control scheme, the second terminal of the third load is connected to the second interface simultaneously with the second terminal of the first load, and the second terminal of the fourth load is connected to the second interface simultaneously with the second terminal of the second load. Therefore, the third load and the first load can operate simultaneously, and the fourth load and the second load can operate simultaneously, but the third load and the second load cannot operate simultaneously, and the fourth load and the first load cannot operate simultaneously.

[0043] In the control scheme of this application, when the first group of loads includes at least a first load and a second load, and the second group of loads includes at least a third load, a fourth load, and a fifth load, the first end of the first load and the first end of the second load are simultaneously electrically connected to the first interface, the first end of the third load, the first end of the fourth load, and the first end of the fifth load are simultaneously electrically connected to the fourth interface, the second end of the first load, the second end of the third load, and the second end of the fifth load are simultaneously electrically connected to the second interface, and the second end of the second load and the second end of the fourth load are simultaneously electrically connected to the third interface.

[0044] Switches SW1 and SW4 are connected to the common terminal LoadCOM on the control board, and switches SW2 and SW3 are connected to the power control terminal LoadCTL on the control board. The second terminal of the third load is connected to the second terminal of the first load. The second terminal of the fifth load can be connected to the second terminal of the third load or the second terminal of the first load. The second terminal of the fourth load is connected to the second terminal of the second load. The first load, the third load, and the fifth load are controlled by switch SW2 in the same control loop, and the second load and the fourth load are controlled by switch SW3 in the same control loop.

[0045] When switches SW1 and SW2 are closed, the power control terminal LoadCTL and the common terminal LoadCOM on the control board are connected, energizing the first and second interfaces and enabling the first load to operate. When switches SW1 and SW3 are closed, the first and third interfaces are energized, enabling the second load to operate. When switches SW2 and SW4 are closed, the second and fourth interfaces are energized, enabling the third and fifth loads to operate. When switches SW3 and SW4 are closed, the third and fourth interfaces are energized, enabling the fourth load to operate. When switches SW1, SW2, and SW3 are closed simultaneously, the first, second, and third interfaces are energized, and the first and second loads operate simultaneously. When switches SW2, SW3, and SW4 are closed simultaneously, the second, third, and fourth interfaces are energized, and the third, fourth, and fifth loads operate simultaneously. In this control scheme, the second terminals of the third and fifth loads are simultaneously connected to the second interface along with the second terminal of the first load, and the second terminals of the fourth and second loads are simultaneously connected to the third interface. Therefore, the third, fifth, and first loads can operate simultaneously, and the fourth and second loads can operate simultaneously, but the third and second loads will not operate simultaneously, the fifth and second loads will not operate simultaneously, and the fourth and first loads will not operate simultaneously.

[0046] When the second terminals of the first load and the third load are simultaneously electrically connected to the second interface, and the second terminals of the second load, the fourth load, and the fifth load are simultaneously electrically connected to the third interface, switches SW2 and SW4 are closed, energizing the second and fourth interfaces, and the third load operates. When switches SW3 and SW4 are closed, energizing the third and fourth interfaces, the fourth and fifth loads operate. When switches SW2, SW3, and SW4 are simultaneously closed, the second, third, and fourth interfaces are energized, and the third, fourth, and fifth loads operate simultaneously. In this control scheme, the third load and the first load can operate simultaneously, the fourth load and the second load cannot operate simultaneously, the fifth load and the second load can operate simultaneously, the third load and the second load cannot operate simultaneously, the fourth load and the first load cannot operate simultaneously, and the fifth load and the first load cannot operate simultaneously.

[0047] like Figure 2 The diagram shown is a schematic of the control scheme of this application. The left side of the diagram is the control board, which includes the power control terminal LoadCTL, the common terminal LoadCOM, switches SW1 to SW5, and interface CN1 on the control board. The right side of the diagram shows the entire load and wiring harness, including six loads Load1 to Load6.

[0048] Figure 2Taking six loads Load1 to Load6 as an example, Load1, Load2, and Load3 form the first group of loads, and Load4, Load5, and Load6 form the second group of loads. Load1 to Load3 and Load4 to Load6 are grouped together, i.e., Load1 and Load4 are in one group, Load2 and Load5 are in another group, and Load3 and Load6 are in yet another group. Each group is controlled by closing or opening switches SW1 to SW5 in the control loop.

[0049] Figure 2 The control board includes five switches SW1 to SW5. One end of switches SW1 and SW5 is connected to the common terminal LoadCOM, and one end of switches SW2, SW3, and SW4 is connected to the power control terminal LoadCTL. There are five interfaces CN1 on the control board, namely the first interface to the fifth interface. The other end of switches SW1 to SW5 on the control board is connected to the five interfaces CN1 on the control board, namely the first interface to the fifth interface. When the switch is closed, the corresponding interface is powered on.

[0050] Figure 2 The overall load and wiring harness includes six loads Load1 to Load6. The first ends of loads Load1 to Load3 are simultaneously electrically connected to the first interface. The second ends of loads Load1 to Load3 are respectively electrically connected to the second interface, the third interface, and the fourth interface. The first ends of loads Load4 to Load6 are simultaneously electrically connected to the fifth interface. The second end of load Load4 is connected to the second end of the first load. The second end of load Load5 is connected to the second end of the second load. The second end of load Load6 is connected to the second end of the third load.

[0051] It is understandable that the second terminals of loads Load1 and Load4 are simultaneously electrically connected to the second interface, the second terminals of loads Load2 and Load5 are simultaneously electrically connected to the third interface, and the second terminals of loads Load3 and Load6 are simultaneously electrically connected to the fourth interface. That is, when switch SW2 is open, the second interface will not be energized, and loads Load1 and Load4 will not work; when switch SW3 is open, the third interface will not be energized, and loads Load2 and Load5 will not work; when switch SW4 is open, the fourth interface will not be energized, and loads Load3 and Load6 will not work.

[0052] When switches SW1 and SW2 are closed, the common terminal LoadCOM and the power control terminal LoadCTL are connected, the first interface and the second interface are energized, and the load Load1 is working. When the load Load1 finishes working and the load Load4 needs to work, switch SW1 is opened, SW2 remains closed, and switch SW5 is closed. That is, the opening or closing of switch SW2 in the control circuit can determine whether the loads Load1 and Load4 are working. At this time, the loads Load1, Load4, LoadCOM, LoadCTL, the first interface, the second interface, the fifth interface, SW1, SW2, and SW5 constitute a minimum control unit.

[0053] When switches SW1 and SW3 are closed, the common terminal LoadCOM and the power control terminal LoadCTL are connected, the first interface and the third interface are energized, and load Load2 is working. When load Load2 finishes working and load Load5 needs to work, switch SW1 is opened, SW3 remains closed, and switch SW5 is closed. That is, the opening or closing of switch SW3 in the control circuit can determine whether loads Load1 and Load4 are working. At this time, loads Load2 and Load5, LoadCOM, LoadCTL, the first interface, the third interface, the fifth interface, SW1, SW3, and SW5 constitute a minimum control unit.

[0054] Similarly, the negative loads Load3 and Load6, LoadCOM, LoadCTL, the first interface, the fourth interface, the fifth interface, SW1, SW4, and SW5 constitute a minimum control unit.

[0055] The control board of the equipment contains the necessary components for the operation of each load. The number of components is related to the number of loads installed in the equipment. In the existing control scheme, one switch in one control loop controls one load. This means that the more loads there are, the more control loops and switches are required, resulting in a larger number of components on the control board. In this application, one end of two or more loads that meet the conditions is controlled by a switch in one control loop, so that one switch controls two or more loads. This can effectively reduce the number of control loops and switches, reduce the required components, and thus save space on the control board.

[0056] The equipment allows for the simultaneous connection of one end of two or more loads to a single interface, controlled by a single switch, depending on the load's operating conditions and the established control circuits and switches. When only one end of each of the two loads in the equipment is controlled by a single switch, the effect of individual control over each load can be achieved.

[0057] When the user starts the device and load Load1 needs to work, switches SW1 and SW2 need to be closed simultaneously to power the first and second interfaces. Similarly, when the device needs load Load2 to work, switches SW1 and SW3 need to be closed simultaneously to power the first and third interfaces. When the device needs load Load3 to work, switches SW1 and SW4 need to be closed simultaneously to power the first and fourth interfaces. Therefore, when loads Load1, Load2, and Load3 are working, switches SW1 through SW4 need to be closed simultaneously.

[0058] When load 4 is required to operate, switches SW2 and SW5 must be closed simultaneously to energize the second and fifth interfaces. When load 5 is required to operate, switches SW3 and SW5 must be closed simultaneously to energize the third and fifth interfaces. Similarly, when load 6 is required to operate, switches SW4 and SW5 must be closed simultaneously to energize the fourth and fifth interfaces. That is, when loads 4, 5, and 6 are operating, switches SW2 through SW5 must be closed simultaneously. Since the second terminal of the fourth load is connected to the second interface at the same time as the second terminal of the first load, when switches SW1, SW2, and SW5 are closed simultaneously, the first, second, and fifth interfaces are energized, and the first and fourth loads operate simultaneously. However, the first and fifth loads, and the first and sixth loads will not operate simultaneously. Similarly, the second and fourth loads, and the second and sixth loads, will not operate simultaneously, nor will the third and fourth loads, or the third and fifth loads.

[0059] According to the control scheme of this application, it has an advantage over the control scheme of the prior art when the equipment has at least four loads and two loads are grouped together. That is, when the equipment has loads Load1 to Load4, Load1 and Load2 are grouped together, and Load3 and Load4 are grouped together, the required control loops are SW1 to SW4, which only requires four control loops. In contrast, the control scheme of the prior art requires five control loops to control four loads.

[0060] The more load the equipment has, the more advantageous the control scheme of this application becomes. When the equipment has eight loads divided into two groups, and one end of one load in one group is connected to one end of one load in the other group at the same time, six control loops are required. When the equipment has ten loads divided into two groups, and one end of one load in one group is connected to one end of one load in the other group at the same time, seven control loops are required. And so on. When the equipment has 2n loads divided into two groups, and one end of one load in one group is connected to one end of one load in the other group at the same time, n+2 control loops are required. That is, when the equipment has twenty loads, the existing control scheme requires twenty-one control loops, while the control scheme of this application only requires twelve control loops under certain conditions.

[0061] like Figure 3 As shown, taking a household washing machine as an example, assume that load Load1 is the main washing valve of the washing machine, load Load2 is the spray valve, load Load3 is the rinsing valve, load Load4 is the heating element, load Load5 is the condenser valve, and load Load6 is the drying fan.

[0062] The first end of the main wash valve, the first end of the spray valve, and the first end of the flushing valve are all connected to the first interface. The second end of the main wash valve, the second end of the spray valve, and the second end of the flushing valve are connected to the second interface, the third interface, and the fourth interface, respectively. The first end of the heating tube, the first end of the condenser valve, and the first end of the drying fan are all connected to the fifth interface. The second end of the heating tube, the second end of the condenser valve, and the second end of the drying fan are connected to the second interface, the third interface, and the fourth interface, respectively.

[0063] When switches SW1 and SW2 are closed, the first and second ports are energized, and the main wash valve operates. If switches SW3 and SW4 are closed at this time, the third and fourth ports are energized, and the spray valve and rinsing valve can operate simultaneously with the main wash valve. However, when the main wash valve is operating, the condenser valve and the drying fan will not operate. When switches SW2 and SW5 are closed, the second and fifth ports are energized, and the heating element operates. If switches SW3 and SW4 are closed at this time, the third and fourth ports are energized, and the condenser valve and the drying fan can operate simultaneously with the heating element. However, when the heating element is operating, the spray valve and the rinsing valve will not operate.

[0064] When switches SW1 and SW3 are closed, the first and third ports are energized, and the spray valve operates. If switches SW2 and SW4 are closed at this time, the second and fourth ports are energized, and the spray valve, rinsing valve, and main wash valve operate simultaneously. However, when the spray valve is operating, the heating element and the drying fan will not operate. When switches SW3 and SW5 are closed, the third and fifth ports are energized, and the condenser valve operates. If switches SW2 and SW4 are closed at this time, the second and fourth ports are energized, and the heating element, condenser valve, and drying fan operate simultaneously. However, when the condenser valve is operating, the main wash valve and rinsing valve will not operate.

[0065] Similarly, when the flushing valve is working, closing switches SW2 and SW3 allows the main wash valve and spray valve to work simultaneously. However, when the flushing valve is working, the heating element and condenser valve will not work.

[0066] In the existing control scheme, only one end of switch SW1 on the control board is connected to the common terminal LoadCOM, while one end of switches SW2 to SW7 are all connected to the power control terminal LoadCTL. In this scheme, each load requires switch SW1 to be closed, and the corresponding switches of each load also need to be closed. That is, if there are six working loads on the equipment, a total of seven control loops and seven corresponding switches need to be set up. The number of control loop devices that need to be installed is large. In actual installation, the control board is easily limited by space, which makes it unable to support more devices. As a result, the equipment cannot add new functions, which has certain defects.

[0067] In the control scheme of this application, one end of switches SW1 and SW5 on the control board is connected to the common terminal LoadCOM, and one end of switches SW2, SW3, and SW4 is connected to the power control terminal LoadCOM. Therefore, according to the technical solution of this application, driving six working loads requires five control loops and five corresponding switches. When the user starts the device, the loads Load1 to Load6 can be controlled by switches SW1 to SW5 in the control loop. This realizes that one control loop controls two or more loads, reduces the number of control loops, and saves the components installed on the control board. When the device adds new functions, there is enough space on the control board to install the various components required for the load to work.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
