Description

Technical Field

[0001] The invention belongs to the technical field of stove electrical performance testing, and relates to an electric ceramic stove electrical performance testing system based on artificial intelligence. Background Art

[0002] As an efficient, environmentally friendly and versatile kitchen appliance, ceramic stoves have gradually occupied an important position in the market. In the manufacturing process of ceramic stoves, it is very important to ensure the reliability and stability of their electrical performance, which is not only related to the safety of product use, but also directly affects the user experience and the market competitiveness of the product.

[0003] In the prior art, there are also some related solutions related to the electrical performance detection of stoves. For example, Chinese patent application publication number CN118777755A discloses an electrical performance testing method and system for an induction cooker, which collects the electrical performance data of the induction cooker and obtains the electrical performance index of the induction cooker accordingly; obtains the comprehensive electrical performance index of the induction cooker according to the electrical performance index, and stores the comprehensive electrical performance index of the induction cooker to obtain the historical comprehensive electrical performance index of the induction cooker; constructs an induction cooker electrical performance test model according to the historical comprehensive electrical performance index, and obtains the electrical performance predicted operating capacity value of the induction cooker accordingly, and finally judges and analyzes the induction cooker, thereby improving the efficiency of the electrical performance test of the induction cooker.

[0004] Although the above schemes have proposed some solutions for the electrical performance testing of stoves, there are still the following limitations: 1. Existing testing methods often only perform simple measurements on the basic electrical parameters of electric ceramic stoves, making it difficult to comprehensively and deeply analyze the electrical performance of electric ceramic stoves under various complex working conditions, and unable to timely discover potential fault hazards and performance defects.

[0005] 2. The existing electrical inspection data of electric ceramic stoves lacks attention to the performance status related to cooling response. During the use of electric ceramic stoves, the furnace temperature may rise excessively due to various reasons (such as long-term, high-load operation). If there is a lack of attention to the autonomous cooling response performance of the electric ceramic stove, it is impossible to accurately evaluate the self-protection ability and electrical safety ability of the electric ceramic stove under abnormal high temperature conditions. Summary of the invention

[0006] In view of this, in order to solve the problems raised in the above background technology, an electric ceramic stove electrical performance testing system based on artificial intelligence is proposed.

[0007] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides an electric performance test system for an electric ceramic stove based on artificial intelligence, the system comprising: an electric load simulation module, used to obtain the rated power and rated current applied by the electric ceramic stove, connect the electric ceramic stove with an electronic load through wires, and control the adaptive power of the electronic load to perform an electric load simulation test.

[0008] The steady-state test module is used to control the different changing characteristics of the power load, including each steady-state load level and each transient load amplitude level, which are numbered as , , detect the electrical data of the ceramic stove under different changing characteristics of the power load, analyze the steady-state characteristics of the ceramic stove rectifier bridge stack components under various steady-state load levels, and the transient response characteristics of the ceramic stove rectifier bridge stack components under various transient load amplitude levels.

[0009] The functional performance detection module is used to construct the electrical function test indicators of each component of the electric ceramic stove based on the analysis content of the steady-state test module, and identify components with abnormal electrical functions.

[0010] Heating performance test module, used to simulate the thermal conductivity of the electric ceramic stove, simulate the cooking function of each appliance under various power loads, and build the thermal conductivity test index of the electric ceramic stove .

[0011] Electric ceramic stove electrical performance integration module, used to analyze the functional integrity indicators of electric ceramic stoves And integrate it with the electrical function test indicators of each component of the electric ceramic stove and the thermal conductivity test indicators of the electric ceramic stove into the electric ceramic stove performance test score to provide electrical performance feedback.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention simulates and detects the electrical operation data of the electric ceramic stove under different steady-state power loads and different transient load conditions. Under steady-state load, the long-term stable performance of components can be detected, and under transient load, the instantaneous abnormal changes can be captured. The performance of each component under different conditions can be more comprehensively understood, thereby more accurately identifying components with abnormal electrical functions and avoiding missed detection or misjudgment due to a single detection condition.

[0013] (2) The present invention uses the rectifier bridge stack components of the electric ceramic stove as the key abnormality identification components. When the rectifier bridge stack components are abnormal, other components are detected one by one, thereby identifying the electrical function test indicators of each component of the electric ceramic stove and finding out the components with abnormal electrical functions, which helps to timely discover and solve potential problems in the production process, and then carry out targeted optimization and adjustment.

[0014] (3) The present invention simulates the electric power of the electric ceramic stove under various cooking functions, analyzes the lateral thermal conductivity efficiency and the longitudinal thermal conductivity efficiency of the electric ceramic stove under various power loads, and constructs a thermal conduction test index for the electric ceramic stove. This can clearly reflect the heat transfer path and efficiency inside the electric ceramic stove, and is helpful for R&D personnel to optimize the structure of the electric ceramic stove.

[0015] (4) The present invention analyzes the functional integrity index of the electric ceramic stove by detecting the cooling response of the electric ceramic stove under excessive temperature. When the electric ceramic stove is under high temperature, its internal electronic components, heating wires, circuits, etc. may be damaged or even burned due to long-term high temperature. By detecting the cooling response, it can be ensured that the electric ceramic stove can be cooled in time when the temperature is too high, thereby protecting the internal components and reducing the failure and damage of the components caused by overheating, thereby effectively preventing safety accidents such as fire and burns caused by overheating, and protecting the life and property of users.

At the same time, it can timely discover the potential safety hazards such as local overheating and heat accumulation that may occur during the operation of the electric ceramic stove.

When the electric ceramic stove is under high temperature, the electronic components, heating wires, circuits, etc. inside the electric ceramic stove may be damaged or even burned due to long-term high temperature. By detecting the cooling response, it can be ensured that the electric ceramic stove can be cooled in time when the temperature is too high, thereby protecting the internal components and reducing the failure and damage of the components caused by overheating, thereby effectively preventing safety accidents such as fire and scalding caused by overheating, and protecting the life and property of users.
