For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0049] The present application introduces a dishwasher heating control method, the dishwasher includes at least two heating devices for heating washing water, the dishwasher starts a washing program, at least two heating devices are selected to be turned on, it is judged whether the selected heating device of the dishwasher is partially faulty, if so, the dishwasher continues to run the washing program until the end, thereby improving the heating efficiency of the dishwasher and meeting the convenient use requirements of the user.
[0050] In the prior art, when the heating device of the dishwasher malfunctions, the washing process of the dishwasher is interrupted, thereby causing the washing process of the tableware to be unable to be normally completed, reducing the user experience, and the interruption of the washing process in the middle cannot meet the user's use demand for the convenient and fast cleaning of the tableware by the dishwasher. Therefore, some dishwashers are provided with a compensation washing program. When the heating device malfunctions, the washing program of the dishwasher continues, and the user is prompted of the malfunction of the heating device after the washing is completed. This setting enables the washing process to continue, but the water temperature in the compensation washing operation cannot reach the washing temperature, and although the compensation washing is performed, the washing rate of the dishwasher is reduced.
[0051] At present, the dishwasher can only wash the tableware clean by relying on heating. After the dishwasher is started, the heating device is started. Only the method of increasing the power is used to realize the rapid increase of the washing temperature, which causes great waste of resources. The continuous heating of the heating device causes waste of energy, and the excessively high water temperature can cause damage to the plastic parts.
[0052] The dishwasher heating control method introduced in the present application can simultaneously start at least two heating devices after the dishwasher program is started, so that the washing water temperature can be rapidly increased in a short time, thereby effectively improving the working efficiency and washing rate of the dishwasher. By judging whether the heating device of the dishwasher is partially malfunctioning, if so, the dishwasher continues to run the washing program until it is completed, thereby avoiding the existing dishwasher which stops the washing process as soon as the heating device malfunctions, and cannot meet the user's convenient use demand for clean tableware.

[0055] T1: set temperature; t: time required to reach the set temperature T1; T2: set temperature; t0: time required to reach the set temperature T2; T3: set temperature; T M : temperature limit value; the above parameters are all pre-set when the program is set.
[0056] T0: initial temperature; when the dishwasher starts the washing program, the temperature of the washing water is detected, and the detection value is recorded as the initial temperature T0.
[0057] T S : real-time water temperature; the temperature of the washing water is detected in real time by a water temperature sensor.
[0058] In this embodiment, T1 < T3 < T M , T2 < T3 < T M By setting detailed control parameters, the dishwasher heating control is more intelligent and automated.
[0059] In this embodiment, after the dish washing machine is started, the user can select a corresponding washing program according to the needs, and after the user completes the selection, the dish washing machine starts the washing program, and at least two heating devices are turned on. Through the above setting, the temperature of the washing water can be quickly raised in a short time. Compared with the method of raising the power to quickly raise the temperature of the washing water, the present setting is more effective, convenient and reduces energy waste.
[0060] In this embodiment, after the dish washing machine starts the washing program for a set time t, it is judged whether the real-time water temperature T S of the washing water reaches the set temperature T1. If yes, it is determined that the working states of the selected heating devices are normal, and if no, it is determined that at least part of the heating devices is faulty. Through this setting, it is not necessary to set a timer in the dish washing machine to time the heating time of the heating devices and then compare it with the set time, so that the working states of the first heating device and the second heating device can be simply and conveniently judged, and the components in the dish washing machine are also reduced, thereby reducing the production cost.
[0061] In this embodiment, if the real-time water temperature T S of the washing water reaches the set temperature T1 within the set time t, it is judged that all the selected heating devices are normal, and the selected heating devices of the dish washing machine continue to operate and continue to execute the washing program; if the real-time water temperature T S of the washing water does not reach the set temperature T1 and exceeds the initial temperature within the set time t, it is judged that part of the selected heating devices is faulty; if the real-time water temperature T S of the washing water does not reach the initial temperature within the set time t, it is judged that all the selected heating devices are faulty, and the washing program is stopped and a fault prompt information is sent. Through the above setting, it is avoided that the dish washing machine is started to continue to open when all the heating devices are faulty, thereby reducing the safety of the dish washing machine, and it is also avoided that the water temperature of the washing water is too low when all the heating devices are faulty, thereby reducing the cleaning rate of the dish washing machine.

[0069] if yes, it is determined that the heating device is normal.
[0070] Through the above setting, it can be determined which of the selected heating devices is faulty.
[0071] Another identification process of step S1 in the embodiment is as follows:
[0072] Step S101, marking the selected heating device, starting one of the marked heating devices, and determining whether the real-time water temperature T S increases;
[0073] if not, it is determined that the heating device is faulty;
[0074] if yes, it is determined that the heating device is normal.
[0075] Through the above setting, it can be determined which of the selected heating devices is faulty.
[0076] In the embodiment, the faulty heating device stops running and is not started again, and the dishwasher marks the faulty heating device; preferably, the dishwasher gives a fault prompt at the end of the washing program.
[0077] Through the above setting, the faulty heating device is prevented from continuing to heat and causing energy waste, the dishwasher marks the faulty heating device, and the dishwasher gives a fault prompt at the end of the washing program, thereby facilitating the user to contact the after-sales service for targeted processing.
[0078] In the embodiment, it is determined whether the real-time water temperature T S is greater than or equal to the set temperature T3; if yes, all or part of the running heating devices are intermittently started to heat; if not, the running heating devices continue to be started to heat. Through this setting, energy waste caused by continuous heating of the heating device is avoided.
[0079] In the embodiment, when it is determined that part of the heating devices is faulty or all of the heating devices is faulty, the dishwasher gives a fault prompt to the user through a display device or voice prompt at the end of the washing program, thereby facilitating the user to contact the after-sales service in time to find the cause for processing.
[0080] In the embodiment, the dishwasher is provided with at least one first heating device that is started and stopped simultaneously with the washing pump, and the power of the first heating device is greater than that of other heating devices. After the washing program of the dishwasher ends, the washing pump is turned off, and the first heating device is turned off.
[0081] Through the above setting, the washing water is heated quickly, and the high-power heating device is not needed to be turned off when not needed, thereby reducing energy waste.
[0082] If the fault washing program is executed after judging that the part of the heating device of the dishwasher is faulty, if the part of the heating device which is started and stopped simultaneously with the washing pump is faulty, the washing process of the dishwasher is continued to be completed; if all the heating devices which are started and stopped simultaneously with the washing pump are faulty, the washing program is exited, and a prompt is given to prompt the user whether to continue washing, the time for continuing to wash is long, if the user selects yes, the washing process of the dishwasher is continued to be completed, if the user selects no, the washing program is exited.
[0083] In the embodiment, a temperature limit T M is set in the washing program, whether the real-time water temperature T S in the dishwasher exceeds the set temperature limit T M is judged, if yes, all the heating devices are automatically stopped.
[0084] Through the above setting, energy waste caused by continuous heating of the heating device is effectively avoided, the use cost of the user is reduced, and damage of the plastic parts caused by too high washing water temperature is avoided.
