1. Please help translate - Chinese to English
There are two translation methods for water dispensers: water dispenser refers to a household water dispenser, and drinking fountain refers to a water dispenser used in public places. Based on your summary, I will temporarily assume that the water dispenser you are referring to is a household water dispenser. Therefore, my translation is as follows, hoping to help you O(∩_∩)O~：So called Water Dispenser is a household product aimed to solve the problem of drinkingwater in our daily life. Because it can improve the quality of drinking water and our lifestyle , it is popular among the public. However, as the material living condition improves, people demands for higher performance. Along with its development, some problems of water dispenser start to come out. For example, "long boiling water" resulting from repeatedly heating might do harm to our physical health,and is also a waste of electricity. Currently, most of water dispensers sold in the market uses an entire hardware circuit, which may contain some limitations, like circuit complexity and mono-functioning. Because of inflexibleness and limitations of controlling, some water dispensers only have functions of heating and heat preservation. As a result, the author suggests that it is necessary to improve the control system of current water dispensers. The article mainly introduces the design process of using AT89C52 to make a simple and easy automatic control system of water dispensers, that is, using temperature sensor DS18B20 to measure the temperature and the liquid crystal display LCD1602 to display the Real-time temperature. Only the water temperature is below 70 ℃ will the water dispenser work and boil water. Under other temperature conditions, the automatic heating control system wil cut off the electricity, resulting in energy conservation. What"s more, the lower limit of heating temperature can be adjusted by software. The new system uses AT89C52 as its cybernetics core, so the author focuses on the software programming method and how to use the software to achieve intelligent control of water dispensers. The new system is characterized by simple circuit structure, easy operation, less hardware requirement, lower costs, smaller power consumption and so on.Key Words : water dispenser, DS18B20, AT89C52
2. Complaint letter for washing machine malfunction in English, specific reasons and solutions
Complaint letter for washing machine malfunction (in English) Overview of malfunction and specific reasons: Dear Customer Service,I hope this message finds you well. I am writing to formally lodge a complaint regarding the recent malfunction of the washing machine I purchased from your company. Approximately two weeks ago, I noticed that the washing machine started displaying error code F4 during the rinse cycle. The specific reason for this malfunction, as determined by a technician, is a defective water level sensor. This component is essential for regulating the water intake during different stages of the washing process, and its failure has disrupted the machine"s ability to function properly. Detailed cause analysis: Water Level Sensor Malfunction: The water level sensor is responsible for detecting the water level in the washing machine and adjusting it accordingly. When this sensor malfunctions, it can lead to incorrect water levels, triggering error codes and preventing the machine from completing its cy
