Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and in particular to an energy-saving control system for a pot washing machine and a pot washing machine. Background Technology

[0002] Currently available hot pot basin cleaning machines operate continuously with their main washing and rinsing functions after startup, maintaining high-load operation even when continuous washing is not required. They only stop working when the machine is shut down or the power is cut off. This design leads to significant resource waste, failing to achieve rational utilization of water, electricity, and gas, and also poses challenges to environmental protection and energy conservation, urgently requiring optimization and upgrades to meet the needs of resource conservation. Utility Model Content

[0003] This application aims to provide an energy-saving control system and a washing machine for a pot washing machine, which can reduce the waste of resources caused by the pot washing machine.

[0004] An energy-saving control system for a pot washer according to a first aspect of this application is used to control a pot washer. The pot washer includes a frame, the frame is provided with a cleaning channel and a conveying mechanism passing through the cleaning channel; the conveying mechanism is provided with multiple sets of locking structures at intervals; the inlet of the cleaning channel is provided with two opposing rotation limiting structures and an elastic reset structure connected between the two rotation limiting structures, the two rotation limiting structures and the elastic reset structure are used together to adjust the posture so that the pot falls between two adjacent locking structures on the conveying mechanism; the outlet of the cleaning channel is provided with an outlet baffle assembly, the outlet baffle assembly being rotatably configured; The energy-saving control system for the washing machine includes: A first sensor switch is installed on the washing machine; A first sensing element is disposed on any of the rotation limiting structures and is used to trigger the first sensing switch when the rotation limiting structure is rotated into position. The second inductive switch is located at one end of the outlet stop assembly near the frame; The second sensor is located at the outlet of the cleaning channel and is used to deactivate the triggering of the second sensor switch when the outlet baffle assembly rotates. The control unit is electrically connected to the first inductive switch, the second inductive switch, and the cleaning system of the washing machine.

[0005] The washing machine according to a second aspect of this application includes the energy-saving control system for the washing machine as described in the first aspect embodiment.

[0006] The energy-saving control system and washing machine of this application embodiment, through the cooperation of a first inductive switch and a first sensor, achieve precise monitoring of the state of the rotation limit structure. This allows for accurate feedback that the basin has entered the washing channel and is in position when it is adjusted by the rotation limit structure to accurately fall between the locking structures of the conveying mechanism. Simultaneously, the second inductive switch and the second sensor reflect changes in the outlet baffle assembly. The rotation of the outlet baffle assembly is achieved by the conveying mechanism moving the basin and the basin further pushing the outlet baffle assembly. This allows for effective feedback on whether the basin has reached the end of the washing channel. Ultimately, the control unit can control the start and stop of the washing system upon receiving the switching signals from the first and second inductive switches. This minimizes the operating time of the washing system when there is no basin in the washing channel, reducing resource waste. Furthermore, the energy-saving control system of this application embodiment does not require adjustments to the original structure of the washing machine, allowing the original equipment to continue to be used, improving user experience while further reducing resource waste.

[0013] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0014] To better describe the energy-saving control system and washing machine of the washing machine according to the embodiments of this application, a brief introduction to the washing machine is given below, such as... Figures 1 to 6 As shown, the pot washing machine includes a frame 100 and a washing system 300.

[0015] The aforementioned frame 100 is provided with a cleaning channel 110 and a conveying mechanism 120 passing through the cleaning channel 110; the conveying mechanism 120 is provided with multiple sets of locking structures at intervals; the inlet of the cleaning channel 110 is provided with two opposing rotation limiting structures 140 and an elastic reset structure 150 connected between the two rotation limiting structures 140, the two rotation limiting structures 140 and the elastic reset structure 150 are used together to adjust the posture so that the basin falls between two adjacent locking structures on the conveying mechanism 120; the outlet of the cleaning channel 110 is provided with an outlet baffle assembly 160, the outlet baffle assembly 160 being rotatably set.

[0016] The aforementioned cleaning system 300 includes a spray system and a brush system, both electrically connected to the control unit 250. Under the control of the control unit 250, the spray system sprays water onto the basin within the cleaning channel 110. Under the control of the control unit 250, the brush system scrubs the basin within the cleaning channel 110.

[0017] The water spraying of the above-mentioned spray system can be controlled by the control unit 250 through the solenoid valve that controls the on and off of the spray pipe of the spray system. The spray system may include a main rinsing system and a rinsing system after cleaning.

[0018] The aforementioned brush system may include a rotating brush, a mechanism for raising and lowering the rotating brush, and a mechanism for driving the rotating brush. These mechanisms may be controlled by the control unit 250 so that the control unit 250 can automatically control the washing process of the basin.

[0019] The bottom ends of the two rotation limiting structures 140 mentioned above are provided with opposing toggle blocks 141, such as... Figure 5 As shown, this is to move the basin between the locking structures, thus securing the basin on the conveying mechanism 120. During the process of the moving block 141 moving the basin between the locking structures, the rotation limiting structure 140 also rotates synchronously. Therefore, by detecting the rotation state or position of the rotation limiting structure 140, it can be determined whether the basin has fallen between the locking structures, thereby determining whether the basin has effectively entered the cleaning channel 110.

[0020] When the aforementioned actuating block 141 is squeezed and rotated by the basin, the two rotation limiting structures 140 will rotate synchronously and pull up the elastic reset structure 150. After the basin moves further into the cleaning channel 110, the two rotation limiting structures 140 can be reset by the restoring force of the elastic reset structure 150.

[0021] The aforementioned conveying mechanism 120 can be a chain conveying mechanism 120, and the clamping mechanism can be directly fixed to the chain.

[0022] The aforementioned outlet baffle assembly 160 is located at the tail end of the washing channel 110 of the washing machine. When no basins are pressing against the outlet baffle assembly 160 via the conveying mechanism 120, the end of the outlet baffle assembly 160 furthest from the bottom of the frame 100 will rotate in a first direction due to gravity. When basins are pressing against this end of the outlet baffle assembly 160 via the conveying mechanism 120, the pressure at this end will exceed gravity, causing it to rotate in a second direction, opposite to the first direction. During this rotation, the spatial position of the end of the outlet baffle assembly 160 closest to the bottom of the frame 100 changes. This change in spatial position can be detected to determine whether a basin has been conveyed out of the washing channel 110.

[0023] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings and the above-mentioned washing machine. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0024] See Figures 1 to 6 As shown in one embodiment of this application, an energy-saving control system for a washing machine is provided. This energy-saving control system includes: The first sensor switch 210 is installed on the pot washer; The first sensing element 220 is disposed on any rotation limiting structure 140 and is used to trigger the first sensing switch 210 when the rotation limiting structure 140 is rotated into position. The second inductive switch 230 is located at one end of the outlet stop assembly 160 near the frame 100; The second sensor 240 is disposed at the outlet of the cleaning channel 110 and is used to release the triggering of the second sensor switch 230 when the outlet baffle assembly 160 rotates. The control unit 250 is electrically connected to the first inductive switch 210, the second inductive switch 230, and the cleaning system 300 of the washing machine.

[0025] In this embodiment, the cooperation of the first inductive switch 210 and the first sensor 220 enables precise monitoring of the state of the rotation limiting structure 140. This allows for accurate feedback that the basin has entered the cleaning channel 110 and is in position when the basin is adjusted by the rotation limiting structure 140 to accurately fall between the locking structures of the conveying mechanism 120. Simultaneously, the second inductive switch 230 and the second sensor 240 can reflect changes in the outlet baffle assembly 160. The rotation of the outlet baffle assembly 160 is achieved by the conveying mechanism driving the basin to move and the basin further pushing the outlet baffle assembly 160. This allows the second inductive switch 230 and the second sensor 240 to effectively provide feedback on whether the basin has reached the end of the cleaning channel 110. Ultimately, the control unit 250 can control the start and stop of the washing system 300 of the washing machine upon receiving the switching signals from the first inductive switch 210 and the second inductive switch 230. This minimizes the running time of the washing system 300 when there are no basins in the washing channel 110, thereby reducing resource waste. Furthermore, in this embodiment, the energy-saving control system for the washing machine does not require any adjustments to the original structure of the washing machine, allowing the original equipment to continue to be used. This improves the user experience while further reducing resource waste.

[0026] The aforementioned first inductive switch 210 is installed on the washing machine and can be in a fixed position. The aforementioned first sensing element 220 is installed on any rotation limiting structure 140, so that the spatial position can be changed by the rotation of the rotation limiting structure 140. In this way, by keeping the first inductive switch 210 and the first sensing element 220 at a suitable distance, or keeping the sensing intensity between the two at a suitable range, the first inductive switch 210 cannot complete the sensing (i.e., the switch state cannot be switched) when the first sensing element 220 has not rotated into position with the rotation limiting structure 140 (rotation into position can be understood as the toggle block 141 moving the basin to the position between the locking structures). Conversely, when the first sensing element 220 rotates into position with the rotation limiting structure 140, the first inductive switch 210 can complete the sensing. The control unit 250 can determine whether the basin has entered the washing channel 110 by detecting the change of this switch signal.

[0027] The second sensor 240 is located at the outlet of the cleaning channel 110 (it can be any location near the outlet, as long as the second sensor 240 and the second sensor switch 230 can complete the sensing). It can be in a fixed position. The second sensor switch 230 is located at the end of the outlet baffle assembly 160 near the frame 100. The spatial position can be changed by rotating the outlet baffle assembly 160. By keeping the second sensor switch 230 and the second sensor 240 at a suitable distance, or keeping the sensing intensity between them within a suitable range, the second sensor switch 230 can be made to complete the sensing when it is not rotated to the position with the outlet baffle assembly 160, and vice versa. The control unit 250 can determine that the basin has been sent out of the cleaning channel 110 by detecting the change of this switch signal.

[0028] The control unit 250 is electrically connected to the first induction switch 210, the second induction switch 230, and the cleaning system 300 of the washing machine. When the first induction switch 210 indicates that the basin has entered the cleaning channel 110, the control unit controls the spray system and the brush system to work. When the second induction switch 230 indicates that the basin has exited the cleaning channel 110, the control unit controls the spray system and the brush system to stop working. This achieves automatic control of the spray system and the brush system, effectively reducing the time that the spray system and the brush system work ineffectively.

[0029] Furthermore, the control unit 250 can calculate the time to start the rinsing and cleaning action by matching the transmission speed. That is, after the first sensor switch 210 sends a signal to the control unit 250, the control unit 250 calculates the time it takes for the basin to reach the rinsing spray pipe and starts the rinsing spray pipe in advance, at which time the brush does not work. The control unit 250 can also delay the start of the rinsing and cleaning action by calculating the end time of the previous action. That is, if the previous action is brush washing, the rinsing spray pipe is started after the brush washing is completed; this is the brush working procedure. The control unit 250 can also delay and pause the operation of the spray system when the second sensor switch 230 indicates that the basin has not been removed. When the basin is removed, the spray system resumes the unfinished actions. There are many other energy-saving control methods, which will not be elaborated here.

[0030] It should be noted that the first inductive switch 210 and the first sensor 220 can be interchanged to achieve the same function, and should also fall within the protection scope of this application. The second inductive switch 230 and the second sensor 240 can also be interchanged to achieve the same function, and should also fall within the protection scope of this application.

[0031] In some implementations, reference Figure 5 The elastic reset structure 150 uses a spring.

[0032] In this embodiment, a spring is directly used as the elastic reset structure 150, which is not only inexpensive but also has the ability to operate stably for a long time. In addition, in case of abnormalities such as incomplete reset, the spring can be replaced to quickly complete the repair.

[0033] In some implementations, reference Figure 5 The top ends of the two rotation limiting structures 140 are provided with protrusions, and the protrusions on the two rotation limiting structures 140 are arranged opposite to each other. The first sensing element 220 is disposed on either protrusion.

[0034] In this embodiment, the first sensing element 220 is disposed on any protruding structure, which also allows the first sensing element 220 to obtain a larger displacement when it rotates with the rotation limiting structure 140, which is more conducive to the sensing operation of the first sensing element 220 and the first sensing switch 210.

[0035] In some implementations, reference Figure 5 The elastic reset structure 150 is connected between the two protruding structures. This arrangement allows for better fixation of the elastic reset structure 150; for example, it can be directly fitted onto the protruding structures for fixation, thereby improving the fixation strength.

[0036] In some implementations, reference Figure 3 A partition 130 is provided at the outlet of the cleaning channel 110. The partition 130 is used to separate the cleaning channel 110 from the equipment compartment located in the frame 100. The second sensor 240 is provided on the partition 130. The end of the outlet baffle assembly 160 near the frame 100 is positioned close to the second sensor 240 when it is not rotated.

[0037] The aforementioned partition 130 is used to divide the space of the frame 100, so that components such as controllers and motors that need to be effectively separated from water are effectively isolated from the cleaning channel 110, that is, to achieve dry and wet separation.

[0038] In this embodiment, the second sensor 240 is fixed directly using the existing partition 130, which allows the second sensor 240 to be as close as possible to the end of the outlet baffle assembly 160 near the frame 100. This not only eliminates the need to add an additional fixing bracket to fix the second sensor 240, but also effectively improves the accuracy and stability of the sensing function between the second sensor 240 and the second sensor switch 230.

[0039] In some implementations, reference Figure 6 The aforementioned energy-saving control system for the washing machine also includes: The mode switching switch 270 is mounted on the rack 100 and is electrically connected to the control unit 250.

[0040] In this embodiment, the mode switching switch 270 can switch the washing machine to continuous operation mode in the event of a failure of the control unit 250. That is, the spray system and brush system inside the washing machine will continue to operate, so that the washing machine is in a continuous cleaning state. This method can ensure the normal operation of the washing machine in the event of a failure, so that the user can maintain normal production and operation.

[0041] In some embodiments, the first inductive switch 210 is a strong magnetic switch, and the first sensing element 220 is a strong magnetic element.

[0042] In this embodiment, the first inductive switch 210 is a strong magnetic switch and the first sensing element 220 is a strong magnetic element. The combination of the two results in high sensing sensitivity and strong resistance to interference from oil and water vapor in the working environment of the washing machine. It can stably and accurately monitor the state of the rotation limit structure 140 and avoid false feedback. At the same time, the strong magnetic component has good durability and long life, which can reduce the frequency of failure and maintenance, ensure the stable operation of the control system, and reduce the cost of use.

[0043] In some embodiments, the second inductive switch 230 is a strong magnetic switch, and the second sensing element 240 is a strong magnetic element.

[0044] In this embodiment, the second inductive switch 230 is a strong magnetic switch and the second sensing element 240 is a strong magnetic element. The combination of the two results in high sensing sensitivity and strong resistance to interference from oil and water vapor in the working environment of the washing machine. It can stably and accurately monitor the state of the rotation limit structure 140 and avoid false feedback. At the same time, the strong magnetic component has good durability and long life, which can reduce the frequency of failure and maintenance, ensure the stable operation of the control system, and reduce the cost of use.

[0045] It should be noted that the inductive switch and sensing element can also be other types of devices, such as weak magnetic switches, infrared detectors, and micro switches. The specific type can be flexibly set according to actual needs. If a micro switch is used, the sensing element can be understood as an abutment part, which is used to trigger the micro switch when the rotation limit structure 140 is rotated to the position and the outlet stop assembly 160 is rotated to the position.

[0046] In some implementations, reference Figure 6 The aforementioned energy-saving control system for the washing machine also includes: The operation instruction unit 260 is electrically connected to the control unit 250.

[0047] In this embodiment, an operation indicator unit 260 electrically connected to the control unit 250 is added, which can intuitively provide feedback on the system's operating, standby, and fault status, allowing operators and maintenance personnel to quickly judge the equipment's operating condition; if an abnormality occurs, the problem direction can be located in a timely manner, reducing troubleshooting time, improving equipment operation and maintenance efficiency, and reducing the risk of misoperation due to unclear status.

[0048] The aforementioned operation indicator unit 260 may include at least one of the following display devices: indicator lights, digital tubes, display screens, etc.

[0049] In some implementations, the control unit 250 is the controller of the washing machine.

[0050] In this embodiment, the control unit 250 is set as the original controller of the washing machine, eliminating the need for additional control hardware. Existing components of the equipment can be directly reused, saving hardware costs and installation procedures, and avoiding compatibility issues between new components and the original system. Furthermore, the original controller is already compatible with the washing machine's operating conditions, ensuring control accuracy and stability, simplifying the system structure, and reducing the difficulty of later maintenance.

[0051] The controllers mentioned above can be DSP, ARM, microcontroller, PLC, etc. The specific type can be flexibly selected according to the actual data processing requirements. For example, Siemens S7 series PLC can be selected.

[0052] This application also provides a pot washing machine, which includes the energy-saving control system described above. Because the pot washing machine has the energy-saving control system, it possesses all the beneficial effects brought by the energy-saving control system.

[0053] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
