Problems solved by technology

The inventors of the present application documents have found in research that this type of dishwasher has the following defects during actual use: when the dishwasher is in the washing process, its washing pump and heating equipment are all in operation, and the internal temperature is generally within the range of reach around 70°C
After the door of the dishwasher is closed again, the cold air entering the dishwasher will expand rapidly under the action of high temperature, which will generate a strong thrust on the door of the dishwasher, which will easily cause the door of the dishwasher to be abnormally closed. Open, affecting the safety and reliability of the dishwasher

Embodiment 1

[0056] see image 3 , in this embodiment 1, after the dishwasher is powered on and started, the washing pump and the heating equipment start to run. During this process, the state of opening and closing the door of the dishwasher is monitored in real time. When it is detected that the door of the dishwasher is opened, the control The washing pump and heating equipment stop running, and continue to monitor the door opening and closing status of the dishwasher in real time. When the door of the dishwasher is closed again, only the washing pump is turned on, and the heating equipment is controlled to continue to stop. After the washing pump runs for T, Turn on the heating device again. In this way, within the set time T after the door of the dishwasher is closed again, the water sprayed from the spray arm of the dishwasher is cold water, which reduces the internal temperature of the dishwasher and can effectively suppress the internal temperature of the dishwasher. Excessive hea...

Embodiment 2

[0058] see Figure 4 , in this embodiment 2, after the dishwasher is powered on, the washing pump and heating equipment start to run. During this process, the door opening and closing status of the dishwasher is monitored in real time. The washing pump and heating equipment stop running, and continue to monitor the door opening and closing status of the dishwasher in real time. When the door of the dishwasher is closed again, the washing pump is turned on, and the heating equipment is controlled to stop running periodically for a set time T. That is, within the set time T after the door of the dishwasher is closed, the heating device periodically stops running, and in each cycle, the ratio of the time spent between stopping and running can be adjusted. Typically, the time spent between stopping and running The time ratio is 1:1. Since the heating equipment stops running periodically within the set time T after the dishwasher is closed, the water flow sprayed from the spray ar...

Embodiment 3

[0060] see Figure 5 , Embodiment 3 combines Embodiment 1 and Embodiment 2. Specifically, after the dishwasher is powered on, the washing pump and heating equipment start to run. During this process, the state of opening and closing the door of the dishwasher is monitored in real time. When it is detected that the door of the dishwasher is opened, the washing pump and heating equipment are controlled. Stop running, continue to monitor the door opening and closing status of the dishwasher in real time, when the door of the dishwasher is closed again, start the washing pump to run, and control the heating equipment to stop running continuously for the set time t and periodically within the set time T Stop running for a set time T-t. For example, the heating device can be controlled to stop running continuously within a set time t after the door of the dishwasher is closed again, and then the heating device can be controlled to stop running periodically for a set time T-t. Thro...

Abstract

An embodiment of the invention provides a dish washing machine and a heating control method and device for same, and belongs to the field of dish washing machines. The method comprises the following steps: detecting a door of the dish washing machine in a washing process is opened or not; controlling a washing pump and heating equipment to stop running under the condition that the door of the dish washing machine is opened; detecting whether the door of the dish washing machine is closed again or not; and when the internal temperature of the dish washing machine exceeds a preset temperature Ts and the door of the dish washing machine is closed again, starting the washing pump and reducing the heating power of the heating equipment in a set time T after the door of the dish washing machine is closed again. According to the technical scheme provided by the embodiment, the door of the dish washing machine can be stopped from being opened abnormally, and therefore, the use safety and reliability of the dish washing machine are improved.

Description

technical field [0001] The present invention relates to the field of dishwashers, in particular to a heating control method and device for dishwashers, and further, the present invention also relates to a dishwasher and a machine storing instructions for executing the heating control method of dishwashers readable storage media. Background technique [0002] A dishwasher is a device that uses nozzles to spray high-pressure washing water to clean tableware. It generally includes a dishwasher body that forms a cleaning room. A tableware input port is formed on the body, and a door body that closes the cleaning room is arranged at the tableware input port. . [0003] If the door of the dishwasher is opened during the washing process, the washing pump used to drive the washing liquid and the heating equipment used to heat the washing liquid will stop running to prevent high-temperature water from rushing out of the dishwasher. cause some damages. [0004] For a dishwasher usi...
