[0047] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0050] The present application provides an energy-saving heating method for a dishwasher with differential and non-differential heating, and the main process of the method is described as follows.

[0051] like Figure 1 As shown:

[0052] Step S101: Obtain the total amount of tableware.

[0053] The total amount of tableware is determined by the type and quantity of tableware. In the embodiment of the present application, a camera is set on the dishwasher to obtain pictures of the tableware, and then the type and quantity of the tableware are obtained based on image recognition technology; the above-mentioned image recognition technology is a commonly used technical means in the relevant field and will not be repeated here.

[0054] After obtaining the type and quantity of tableware according to the image recognition technology, the total amount of tableware can be obtained according to the type and quantity of the tableware; a tableware quantity comparison table is pre-stored in the database, which stores information such as the type and quantity of tableware and the corresponding total amount of tableware. After obtaining the type and quantity of tableware, the total amount of tableware can be obtained by combining with the tableware quantity comparison table; for example, the total amount of tableware corresponding to a bowl is 1, the total amount of tableware corresponding to a plate is 2, and the total amount of tableware corresponding to a soup bowl is 3; that is, the total amount of tableware corresponding to different types of tableware is pre-set. When calculating the total amount of tableware, you only need to multiply the total amount of tableware corresponding to different types of tableware by the number of tableware to get the total amount of tableware for this dishwashing job.

[0055] Step S102: Calculate the required volume of cleaning water according to the total amount of tableware.

[0056] In the embodiment of the present application, the total amount of tableware and the volume of cleaning water are preset to be 1:1; therefore, after obtaining the total amount of tableware, the volume of cleaning water can be obtained according to the preset ratio.

[0057] Step S103: Detect the temperature of the cleaning water and select the working mode of the heating wire according to the temperature and volume of the cleaning water.

[0058] The temperature of the cleaning water can be detected by the temperature detection module. In the embodiment of the present application, the temperature detection module includes a temperature sensor, and the temperature of the cleaning water can be detected by the temperature sensor.

[0059] After obtaining the temperature of the cleaning water, the temperature difference is first calculated based on the temperature of the cleaning water and a preset temperature threshold; the temperature threshold here refers to the temperature of the cleaning water required for the dishwasher to wash dishes, that is, after adding cleaning water to the dishwasher, the cleaning water needs to be heated to the temperature represented by the temperature threshold before it can be used; then the pre-stored working mode relationship table is called up, and then the working mode of the heating wire is obtained based on the temperature difference, the volume of the cleaning water and the working mode relationship table.

[0060] The working mode relationship table here includes the temperature difference, the volume of the cleaning water, the working mode of the heating wire, and the corresponding relationship between the three; therefore, after obtaining the three of them, the working mode of the heating wire can be obtained. After obtaining the temperature and volume of the cleaning water, the working mode of the heating wire can be selected; in the embodiment of the present application, the working modes of the heating wire include two, wherein the first mode is to use one heating wire for heating alone; the second mode is to use two heating wires for heating together.

[0061] In the embodiment of the present application, the heating power of the heating wire is set to be constant, and the heating wire is also a resistance wire. As the working time of the heating wire increases, the energy consumption power of the heating wire increases, and the longer the working time, the greater the rate of increase of the energy consumption power. Therefore, in order to save energy consumption, it is necessary to ensure that the heating wire works within a certain working time; that is, the working time of the heating wire cannot exceed the set heating time threshold, then within the heating time threshold, the first mode is used for heating, and if it exceeds the time threshold, the second mode is used for heating.

[0062] For example, if the total amount of tableware is 5, then the volume of cleaning water is also five units; setting a heating wire to heat for one unit time and consume one unit of energy power can increase the temperature of one unit volume of cleaning water by one degree Celsius; then for a heating wire, in order to complete this heating work, it needs to heat for five unit times, and the heating time threshold is three unit times, then at this time, the five unit times exceed the three unit times, then it is necessary to select the second mode, that is, the two heating wires heat together, because the two heating wires are exactly the same heating wires, then for this heating work, only the two heating wires need to heat for 2.5 unit times; in this way, on the one hand, energy consumption can be reduced, and on the other hand, it can be completed in a shorter time, which improves the heating efficiency; similarly, if the time required for heating is less than the heating time threshold, then just select the first mode.

[0063] In this way, the energy consumption of the two heating wires is always kept within a reasonable range during operation, and there will be no abnormal energy consumption due to excessive working time, which will lead to energy waste. It also improves the heating power, reduces the heating time, reduces energy consumption, and reduces waste.

[0064] In the first mode, a single heating wire is used for heating. In this mode, there will always be a problem: if one heating wire is used for heating for a longer time, the total working time of the two heating wires will be different or differ greatly. Therefore, in the first mode, it is also necessary to monitor the working time of the heating wire. In the embodiment of the present application, the steps for monitoring the working time of the heating wire in the first mode are as follows.

[0065] In the first mode, the time module is used to record the working time of the heating wire; then the working time is compared with the preset time threshold; if the working time value is not less than the time threshold, the currently working heating wire is controlled to stop, and the other heating wire is controlled to work; it can be understood that the time threshold here is the pre-set working time threshold of the heating wire; that is, the working time of each heating wire cannot exceed the preset time threshold. In this way, the difference between the total working time of the two heating wires can be greatly reduced.

[0066] Similarly, when the time module records the working time of the heating wire, it will also record the usage time of the heating wire; then the usage time is compared with the preset service life threshold. If the usage time value is not less than the service life value, an alarm message is output; then the usage time and the information of the heating wire are uploaded to the cloud platform. In this way, the service life of the heating wire can be monitored.

[0067] Through the time module, the working time and usage time of the heating wire are recorded locally and uploaded to the cloud platform, thereby realizing the recording of the working time data and usage time data of the heating wire, and having more detailed control over the use of the heating wire, so that the two heating wires can always maintain reasonable energy consumption during the working process, and can also improve the heating efficiency, reduce the heating time and reduce energy consumption.

[0069] In order to better execute the program of the above method, the present application also provides an intelligent terminal, which includes a memory and a processor.

[0070] The memory may be used to store instructions, programs, codes, code sets or instruction sets.
