Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a dishwasher fault detection method and device, and a storage medium. Background Art

[0002] With the development of society, people pay more and more attention to food safety. Commercial dishwashers have become essential cleaning equipment in restaurant kitchens, and they are used very frequently. Whether the dishwasher can be used normally has become a constraint on the normal operation of the restaurant. When the dishwasher fails to put the drying agent, the rinsing and drying effect will be particularly poor. The tableware cannot be dried quickly when it comes out of the dishwasher, which easily leads to the hidden danger of tableware being contaminated again. At this time, the merchant will report the problem, and the dishwasher supplier will send after-sales engineers to the site for repair. First, the engineer will judge the fault point on site, mainly to check the working condition of the detergent. After determining the problem point, he will notify the company to provide replacement parts. Repair and replacement on site will have a relatively low operating efficiency, which will seriously affect the normal use of the merchant.

[0003] In the above scheme, when there is a problem with the dishwasher's drying agent, the user will first feel that the tableware cannot be dried quickly, and the merchant will take the initiative to contact the dishwasher supplier to report the problem. After the after-sales engineer arrives, he must first check and reproduce the fault of the dishwasher, determine the faulty parts of the dishwasher based on the on-site situation, and then decide whether it needs to be repaired or replaced. If it is determined that the faulty parts need to be replaced, the after-sales engineer needs to return to the warehouse to pick up or send the replacement parts to the merchant, and then replace the faulty parts to eliminate the fault and restore the dishwasher to normal operation. The above fault repair needs to be initiated by the merchant, which has already affected the user's use, and the confirmation of the fault point needs to be confirmed on-site by the after-sales engineer, which has relatively high requirements for the experience and ability of the maintenance personnel, and it takes a long time. There is a possibility of misjudgment. When the fault point is confirmed, it is necessary to obtain new replacement parts, which is time-consuming and labor-intensive. In summary, the fault diagnosis and repair process of the solenoid valve and flow meter in the above scheme takes a long time, and the operating efficiency is relatively low, which will affect the normal business of the merchant.

[0004] Therefore, no effective solution has been proposed for the problem in the related art that dishwasher fault diagnosis cannot be performed quickly. Summary of the invention

[0030] In an optional embodiment, when the target pump does not receive a work instruction, determining whether the target motor and the target one-way valve are faulty based on the signal feedback information of the target motor and the signal on-off information of the target one-way valve includes at least one of the following: when the signal feedback information of the target motor is obtained that the encoder of the target motor is in a feedback signal state, and the signal on-off information of the target one-way valve is obtained that the target one-way valve is in a disconnected state, determining that the target pump motor is faulty and the target one-way valve is not faulty; when the signal feedback information of the target motor is obtained that the encoder of the target motor is in a feedback signal state, and the signal on-off information of the target one-way valve is obtained that the target one-way valve is in a disconnected state. When the on-off information shows that the target one-way valve is in the on state, it is determined that both the target pump motor and the target one-way valve are faulty; when the signal feedback information of the target motor is that the encoder of the target motor is in a state without feedback signal, and the signal on-off information of the target one-way valve is that the target one-way valve is in a disconnected state, it is determined that the target one-way valve is faulty and the target pump motor is not faulty; when the signal feedback information of the target motor is that the encoder of the target motor is in a state without feedback signal, and the signal on-off information of the target one-way valve is that the target one-way valve is in the on state, it is determined that both the target one-way valve and the target motor are not faulty.

[0031] In an optional embodiment, the target one-way valve includes a magnetic switch, and the signal on-off information of the target one-way valve includes the on-off signal of the magnetic switch; when the target one-way valve is in an on state, the on-off signal of the magnetic switch is an off signal, and when the target one-way valve is in an off state, the on-off signal of the magnetic switch is an on signal.

[0032] In an optional embodiment, when the stainless steel magnetic ball presses the sealing ring under the action of the spring and the magnetic switch of the target one-way valve detects the magnetic field signal emitted by the magnetic field and sends a connection signal, it is determined that the magnetic switch is closed; when the magnetic switch does not detect the magnetic field signal emitted by the magnetic field and sends a disconnection signal, it is determined that the magnetic switch is disconnected.

[0033] In an optional embodiment, the target one-way valve also includes: a connector, a main body, a spring and a magnetic ball, wherein a lotion circulation channel is arranged in the connector and the main body; one end of the connector is connected to the target water tank, and the other end of the connector is connected to one end of the main body to form a one-way circulation cavity, and a spring and a magnetic ball are arranged in the one-way circulation cavity in sequence starting from the side close to the connector, and a magnetic switch is arranged on the main body for detecting the magnetic field signal of the magnetic ball, and the other end of the main body is connected to the lotion tube of the target pump.

[0034] Specifically, the magnetic ball can be a stainless steel magnetic ball, both ends of the joint are provided with external threads, one end of the main body is provided with internal threads, and the other end of the joint can be connected to one end of the main body through threaded adaptation; the spring is always in a compressed state, and in the absence of external force, it pushes the magnetic ball to close to the lotion flow channel opening on the side of the one-way flow cavity of the main body.

[0035] In an optional embodiment, when the target pump has not received a working instruction, the spring pushes the magnetic ball to be close to the lotion circulation channel opening on the one-way circulation cavity side of the main body, so that one end of the main body is sealed and the magnetic field signal of the magnetic ball is within the detection range of the magnetic switch, and the magnetic switch sends a connection signal; when the target pump receives a working instruction, liquid flows into the lotion tube and pushes the magnetic ball and the spring, and the magnetic ball moves away from the lotion circulation channel opening on the one-way circulation cavity side of the main body, so that one end of the main body is opened and the magnetic field signal of the magnetic ball is outside the detection range of the magnetic switch, and the magnetic switch sends a disconnection signal.

[0036] Optionally, the target one-way valve also includes a sealing ring, which is arranged in the one-way flow cavity close to the main body side. In this way, when the target pump does not receive a working instruction, the spring pushes the magnetic ball to block the lotion flow channel opening of the main body close to the one-way flow cavity side, and the sealing is better.

[0037] Optionally, the target one-way valve also includes a locking nut, which is arranged at the other end of the main body and is threadably adapted to the other end of the main body to prevent the washing pipe from loosening.

[0038] In an optional embodiment, the target pump is a drying agent pump, the target motor is a drying agent pump motor, the target one-way valve is a drying agent one-way valve, and the target water tank is a rinse water tank; or, the target pump is a detergent pump, the target motor is a detergent pump motor, the target one-way valve is a detergent one-way valve, and the target water tank is a main wash water tank.

[0039] In an optional embodiment, after determining whether the target motor and the target one-way valve are faulty based on the signal feedback information of the target motor and the signal on-off information of the target one-way valve, the method further includes: when it is determined that the target motor and / or the target one-way valve are faulty, sending a first prompt message through the dishwasher, wherein the first prompt message is used to indicate that the dishwasher is faulty; and / or when it is determined that the target motor and / or the target one-way valve are faulty, sending a second prompt message to a target terminal having a communication connection relationship with the dishwasher, wherein the second prompt message is used to indicate that the dishwasher connected to the target terminal is faulty.

[0040] In an optional embodiment, a dishwasher is further provided, comprising: a main control board, a target pump, a target motor, a target one-way valve and a target water tank, wherein one end of the target one-way valve is connected to the target water tank, the other end of the target one-way valve is connected to the target pump, the target motor is connected to the target pump, and the target pump adds target material to the target water tank driven by the target motor; the main control board is used to send a working instruction to the target pump; when the target pump receives the working instruction or does not receive the working instruction, the signal feedback information of the target motor and the signal on-off information of the target one-way valve are obtained; and whether the target motor and the target one-way valve are faulty are determined according to the signal feedback information of the target motor and the signal on-off information of the target one-way valve.

[0041] The process of the dishwasher fault detection method is described below with reference to an optional example, as follows:

[0042] Embodiment 1:

[0043] Optionally, an embodiment of the present invention provides a method for adding a one-way valve with a magnetic switch and a reminder to replace the detergent barrel to the dishwasher drying agent delivery port, which can prevent rinse water from flowing back into the drying agent delivery port and affecting the delivery of the drying agent. When the dishwasher detergent is consumed, a reminder message can be sent in time to prompt the operator to replace the detergent barrel. If a malfunction occurs in the delivery of the dishwasher drying agent, the faulty parts can be diagnosed quickly and accurately, and after-sales maintenance personnel can be notified to bring the corresponding parts to the site for repair, thereby improving maintenance efficiency.

[0044] Optionally, the above method can be applied to a dishwasher detergent dispensing structure composed of the following: 1_ detergent bucket, 2_ liquid suction rod, 3_ drying agent pump, 4_ drying agent one-way valve, 5_ rinse water tank, wherein the drying agent one-way valve 4 is installed on the rinse water tank 5.

[0045] like Figure 3 As shown, the structure and working method of the dishwasher drying agent delivery are as follows: the drying agent pump 3 is installed at the front position of the bottom plate of the dishwasher by screws, the inlet of the drying agent pump 3 is connected to the suction rod 2, the drying agent suction rod is inserted into the drying agent barrel, and the outlet is connected to the drying agent one-way valve 4. The drying agent one-way valve is connected to a magnetic switch for detecting the opening and closing of the one-way valve. The drying agent one-way valve 4 is fixed to the rinse water tank 5 by a nut, and the drying agent is delivered into the rinse water tank 5 after passing through the suction rod 2, the drying agent pump 3, and the drying agent connector 4 in sequence.

[0046] like Figure 4 As shown, it is a structural diagram of the side view of the dishwasher drying agent one-way valve, such as Figure 5The figure shows the top view of the one-way valve body and magnetic switch. Its specific structure and working principle are as follows: 4-1 connector, 4-2 magnetic switch, 4-3 main body, 4-4 locking nut, 4-5 lotion tube, 4-6 spring, 4-7 stainless steel magnetic ball, 4-8 sealing ring. The magnetic switch will send out an on-off signal by detecting the magnetic field. It will be connected when there is a magnetic field and disconnected when the magnetic field disappears. At the same time, the connector, main body and locking nut are all injection molded with polypropylene material. This material has the characteristics of acid and alkali resistance, aging resistance, strong injection molding, low price, etc. It is a non-metallic material and will not affect the operation of the magnetic switch.

[0047] like Figure 6 As shown in the figure, liquid (such as rinse water) enters the sealing ring side. When the liquid pressure is greater than the spring force, the stainless steel magnetic ball is pushed away and disengaged from the sealing ring, the pipeline is connected, and the signal is disconnected. When rinsing is completed, the drying agent can be used according to Figure 5 The flow direction shown enters the dishwasher.

[0048] Optionally, by adding a one-way valve with a magnetic switch to the drying agent inlet of the dishwasher, the backflow of rinse water into the drying agent pipe can be completely prevented, and the usage of the drying agent can be detected in real time. After the merchant's drying agent barrel is emptied, a prompt reminder can be given to prevent the problem of tableware not being able to dry quickly due to lack of drying agent.

[0049] Optionally, the working principle of the magnetic switch in the drying agent one-way valve for detecting the delivery of drying agent is as follows: when the drying agent is not delivered, the stainless steel magnetic ball presses the sealing ring under the action of the spring, the rinse water will be blocked, and the concentration of the drying agent in the drying agent tube will not be affected. At the same time, the magnetic switch will detect the magnetic field signal of the stainless steel magnetic ball, the magnetic switch will close, and a connection signal will be sent; when the drying agent starts to be delivered, the working pressure of the drying agent pump will be much greater than the sum of the rinse water pressure and the spring compression force, the drying agent will push the stainless steel magnetic ball away and deliver the drying agent. At the same time, since the stainless steel magnetic ball is far away from the magnetic switch, the magnetic switch will not detect the magnetic field signal and will be disconnected, sending a disconnection signal, and the signal of the magnetic switch is used to detect whether the drying agent is delivered normally.

[0050] like Figure 2 As shown, the verification process of the cross-verification fault location technology of the dishwasher drying agent pump and magnetic switch is as follows: during the process of adding detergent to the dishwasher, the status of the drying agent pump, the drying agent pump motor, and the drying agent one-way valve magnetic switch are monitored, and the faulty parts are accurately determined by cross-verifying the working status of the three.

[0051] When the dishwasher enters the working state, when the main control board issues a drying agent pump working instruction, it is necessary to determine whether the drying agent pump motor encoder feeds back a signal. Regardless of whether the drying agent pump motor encoder feeds back a signal, it is necessary to further determine whether the signal of the drying agent one-way valve magnetic switch is disconnected. If the drying agent pump motor encoder feeds back a signal and the signal of the magnetic switch is disconnected at the same time, the drying agent pump motor and the drying agent one-way valve are both fault-free. If the drying agent pump motor encoder feeds back a signal and the signal of the magnetic switch is not disconnected, the drying agent one-way valve is faulty and the drying agent pump motor is not faulty. If the drying agent pump motor encoder does not feed back a signal and the signal of the magnetic switch is disconnected, the drying agent one-way valve and the drying agent pump motor are faulty at the same time. If the drying agent pump motor encoder does not feed back a signal and the signal of the magnetic switch is disconnected, the drying agent pump motor is faulty and the drying agent one-way valve is not faulty.

[0052] When the dishwasher enters the working state, when the main control board does not issue a drying agent pump working instruction, it is necessary to determine whether the drying agent pump motor encoder feeds back a signal. Regardless of whether the drying agent pump motor encoder feeds back a signal, it is necessary to further determine whether the signal of the drying agent one-way valve magnetic switch is disconnected. If the drying agent pump motor encoder feeds back a signal and the signal of the magnetic switch is disconnected at the same time, the drying agent pump motor is faulty and the drying agent one-way valve is not faulty. If the drying agent pump motor encoder feeds back a signal and the signal of the magnetic switch is not disconnected, the drying agent pump motor and the drying agent one-way valve are faulty at the same time. If the drying agent pump motor encoder does not feed back a signal and the signal of the magnetic switch is disconnected, the drying agent one-way valve is faulty and the drying agent pump motor is not faulty. If the drying agent pump motor encoder does not feed back a signal and the signal of the magnetic switch is disconnected, the drying agent one-way valve and the drying agent pump motor are both faulty.

[0053] Embodiment 2

[0054] Optionally, the above-mentioned embodiment 1 can also be applied to the detergent delivery port, and the mechanical structure and working principle are the same as those of the drying agent delivery port, specifically: the detergent pump is installed at the front position of the bottom plate of the dishwasher by screws, the inlet of the detergent pump is connected to the detergent suction rod, the detergent suction rod is inserted into the detergent barrel, and the outlet is connected to the detergent one-way valve (the detergent one-way valve has the same structure as the previously introduced drying agent one-way valve 4), and a magnetic switch is connected to the detergent one-way valve to detect the opening and closing of the one-way valve. The detergent one-way valve is fixed to the main wash water tank by a nut, and the detergent is delivered to the main wash water tank after passing through the detergent suction rod, the detergent pump, and the detergent one-way valve in sequence. The verification process of the cross-verification fault technology of the detergent pump and the magnetic switch is the same as that of the above-mentioned embodiment 1. Figure 2 The process is the same and will not be described in detail here.

[0055] Through this embodiment, when a drying agent dispensing failure occurs in the dishwasher, the faulty parts can be diagnosed quickly and accurately, and after-sales maintenance personnel can be notified to bring the corresponding parts for on-site repair, thereby improving maintenance efficiency and reducing operating costs. Before the dishwasher affects the user's use, the data analysis of the drying agent pump motor and the one-way valve magnetic switch has been used to diagnose the damage of the parts in advance, and the after-sales personnel have been notified to come to the door for repair, thereby improving the user experience.

[0056] It should be noted that, for the above-mentioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described action sequence, because according to the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present invention.

[0057] According to another aspect of an embodiment of the present invention, a method for detecting a fault in a dishwasher is provided. The device is applied to a dishwasher.
