[0049] The embodiment provided in the present application is an embodiment of a multi-drive device of a dishwasher.

[0050] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] The present application provides a multi-drive device for a dishwasher, comprising: an algorithm module 1, an intelligent switch module 2 and a multi-drive control module 3, such as Figure 1 shown.

[0052] The algorithm module 1 is configured to generate a pulse width modulation signal and a target control voltage based on the received target pump speed demand instruction.

[0053] In some specific embodiments, the algorithm module 1 includes a vector control module 11 .

[0054] The vector control module 11, also known as the field oriented control module, is an advanced motor control method. The vector control module 11 controls the motor's current vector in the direction of the motor's stator electromagnetic field so that the motor's torque direction is consistent with the rotor magnetic field direction, thereby ensuring that the motor outputs the maximum rotational torque and has the best operating efficiency and performance.

[0055] In some specific embodiments, the vector control module 11 includes: a VH output terminal 111 , a VL output terminal 112 , a UH output terminal 113 , a UL output terminal 114 , a WH output terminal 115 and a WL output terminal 116 .

[0056] The intelligent switch module 2 includes a power switch unit 21 , which is in communication with the algorithm module 1 and configured to generate a target voltage based on a pulse width modulation signal.

[0057] In some specific embodiments, Figure 2 As shown, the power switch unit 21 includes a three-phase six-bridge-arm structure circuit 210 and a filter circuit 220 .

[0058] The vector control unit 11 is in communication with the filter circuit 220 and is configured to generate a pulse width modulation signal based on the target pump speed demand instruction.

[0059] In some specific embodiments, Figure 2 As shown, the vector control unit 11 includes: a VH output terminal 111, a VL output terminal 112, a UH output terminal 113, a UL output terminal 114, a WH output terminal 115 and a WL output terminal 116. The vector control module outputs the pulse width modulation signals of VH, VL, UH, UL, WH and WL to the filter circuit 220.

[0060] The filter circuit 220 is connected to the three-phase six-bridge arm structure circuit 210 for communication, and is configured to filter the pulse width modulation signal output by the vector control unit 11 and then input it into the three-phase six-bridge arm structure circuit 210. The filter circuit 220 is used to select the frequency and adjust the shape of the pulse width modulation signal.

[0061] In some specific embodiments, Figure 2As shown, the filter circuit 220 includes: a first resistor 221, a second resistor 222, a third resistor 223, a fourth resistor 224, a fifth resistor 225, a sixth resistor 226, a first capacitor 227, a second capacitor 228, a third capacitor 229, a fourth capacitor 230, a fifth capacitor 231 and a sixth capacitor 232; the input end of the first resistor 221 is communicatively connected to the VH output end 111, and the output end of the first resistor 221 is electrically connected to the input end of the first capacitor 227; the input end of the second resistor 222 is communicatively connected to the VL output end 112, and the output end of the second resistor 222 is electrically connected to the input end of the second capacitor 228; the input end of the third resistor 223 is communicatively connected to the UH output end 113, The output end of the third resistor 223 is electrically connected to the input end of the third capacitor 229; the input end of the fourth resistor 224 is communicatively connected to the UL output end 114, and the output end of the fourth resistor 224 is electrically connected to the input end of the fourth capacitor 230; the input end of the fifth resistor 225 is communicatively connected to the WH output end 115, and the output end of the fifth resistor 225 is electrically connected to the input end of the fifth capacitor 231; the input end of the sixth resistor 226 is communicatively connected to the WL output end 116, and the output end of the sixth resistor 226 is electrically connected to the input end of the sixth capacitor 232; the output ends of the first capacitor 227, the second capacitor 228, the third capacitor 229, the fourth capacitor 230, the fifth capacitor 231 and the sixth capacitor 232 are grounded respectively.

[0062] In other specific embodiments, Figure 2 As shown, the three-phase six-bridge-arm structure circuit 210 includes: a VHN input terminal 211, a VLN input terminal 212, a UHN input terminal 213, a ULN input terminal 214, a WHN input terminal 215, and a WLN input terminal 216; the VHN input terminal 211 is communicatively connected to the output terminal of the first resistor 221, the VLN input terminal 212 is communicatively connected to the output terminal of the second resistor 222, the UHN input terminal 213 is communicatively connected to the output terminal of the third resistor 223, the ULN input terminal 214 is communicatively connected to the output terminal of the fourth resistor 224, the WHN input terminal 215 is communicatively connected to the output terminal of the fifth resistor 225, and the WLN input terminal 216 is communicatively connected to the output terminal of the sixth resistor 226. The filter circuit 220 outputs the filtered pulse width modulation signals of VH, VL, UH, UL, WH, and WL to the three-phase six-bridge-arm structure circuit 210.

[0063] The three-phase six-bridge arm structure circuit 210 is a complex circuit structure, which is composed of a three-phase transformer and six bridge arm circuits. Each bridge arm circuit is composed of two switch tubes. The three-phase transformer distributes the input voltage to the six bridge arms, and after the switch tube control, the six circuit outputs are aggregated to the output capacitor to form a low-fluctuation, high-precision output voltage. Through the pulse width modulation technology, the output voltage is more stable. Under normal operating conditions, in each AC voltage cycle, only one group of bridge arms is turned on, and the other two groups are in the off state. By controlling the on and off of the bridge arm, the direction and magnitude of the output voltage can be controlled. For example, the SPE05M50T chip includes a three-phase six-bridge arm structure circuit 210, and the three-phase six-bridge arm structure circuit 210 also includes: a V-phase output terminal 217, a U-phase output terminal 218, and a W-phase output terminal 219; the V-phase output voltage, the U-phase output voltage, and the W-phase output voltage are output as target voltages respectively, and the on and off of the multi-drive control module 3 are controlled by the direction and magnitude of the target voltage.

[0064] The multi-drive control module 3 is electrically connected to the algorithm module 1 and the intelligent switch module 2 respectively, and is configured to connect the corresponding target pump starting circuit based on the target control voltage and the target voltage.

[0065] The multi-drive control module 3 can connect different target pump starting circuits according to different target voltages. That is, the target voltage corresponds to the target pump starting circuit one by one. The target pump starting circuit controls the operation of the target pump. When the target pump starting circuit is connected, the target pump starting circuit can start the target pump to work.

[0066] In some specific embodiments, the multi-drive control module 3 includes a multi-way switch relay.

[0067] The multi-way switch relay controls multiple target pump starting circuits, that is, it can control the operation of multiple target pumps. The opening signal of each switch in the multi-way switch relay is controlled by the target voltage, and each target voltage can only open one switch.

[0068] In some specific embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the intelligent switch module 2 includes: a V-phase output terminal 217 and a U-phase output terminal 218. The multi-way switch relay is specifically a dual-way switch relay.

[0070] The V0 input pin 316 and the U0 input pin 319 of the dual-way switch relay are electrically connected to the V-phase output terminal 217 and the U-phase output terminal 218 of the intelligent switch module 2, respectively. The coil input terminal 314 and the coil output terminal 315 of the dual-way switch relay are electrically connected to the algorithm module 1, respectively.

The V2 output pin 318 and the U2 output pin 321 of the dual-way switch relay are electrically connected to the second target pump starting circuit 6 respectively; the dual-way switch relay is configured as follows: when the target control voltage between the coil input terminal 314 and the coil output terminal 315 is at a low level, the V0 input pin 316 is electrically connected to the V2 output pin 318, and the U0 input pin 319 is electrically connected to the U2 output pin 321, and the second target pump starting circuit 6 is turned on based on the target voltage between the V2 output pin 318 and the U2 output pin 321; for example, the second target pump starting circuit 6 controls the drain pump of the dishwasher.

[0071] This specific embodiment utilizes the principle of time-sharing operation of multiple target pumps in the dishwasher, and can control the operation of multiple target pumps through a multi-drive device, thereby realizing a single-device multi-drive technical solution, which is simple to install and reduces the cost of use.

[0072] In some specific embodiments, the device further includes: an instruction control module 4, which is in communication with the algorithm module 1 and is configured to generate a target pump speed demand instruction.

[0073] The device of this specific embodiment also includes a command control module 4, so that the entire device has more comprehensive functions, simpler installation, and reduced use costs.

[0074] The present application also provides a method embodiment that is based on the above embodiment. The explanation based on the same name meaning is the same as that of the above embodiment, and has the same technical effect as the above embodiment, which will not be repeated here.

[0075] like Figure 4 As shown, the present application provides a multi-driving method for a dishwasher, comprising:

[0076] Step S401, receiving a target pump speed demand instruction;

[0077] Step S402, generating a pulse width modulation signal and a target control voltage based on a target pump speed demand instruction;

[0080] Thus, the principle of time-sharing operation of multiple target pumps in the dishwasher is utilized, and the operation of multiple target pumps can be controlled by a multi-drive device, thus realizing a single-device multi-drive technical solution, which is simple to install and reduces the use cost.
