Quick Fix for Mizusenmon Stainless Steel Water Dispenser Cooling Issue
Today, we’ll delve into how to repair a Mizusenmon brand stainless steel water dispenser with both hot and cold functions. Currently, the unit is experiencing issues with its cooling function, failing to operate as intended.
Mizusenmon不锈钢饮水机制冷故障的快速解决方案
今天，我们将详细讲解如何维修一台Mizusenmon品牌的不锈钢饮水机。这款饮水机具备热冷双功能，但目前遇到了制冷方面的问题，无法正常工作。
Step One: Inspect the Compressor
The compressor is the heart of the cooling system. First, we need to open the dispenser’s cover, which is typically secured by several screws at the top or side. Ensure the power is off before proceeding. Once the cover is removed, the compressor is in plain sight. Using an ammeter, we measure the current and find it to be 0.00A, clearly indicating the compressor isn’t starting.
步骤一：检查压缩机
压缩机是饮水机制冷系统的心脏。首先，我们需要打开饮水机的盖子。通常，盖子会通过几颗螺丝固定在机身顶部或侧面。确保断开电源后，我们小心地将盖子卸下，这时可以直接看到压缩机。
- 发现：我们用电流表测量压缩机的电流，发现电流显示为0.00A，这清楚地表明压缩机并未启动。
Step Two: Remove the Starter and Overload
Next, we check the starter and overload, crucial components for the safe starting and operation of the compressor. These are usually attached to the side or top of the compressor. Carefully removing these parts for testing, we discover the starter has a resistance of 1.86 megaohms, which means it’s open circuit and no longer functional. The protector also shows an open circuit, suggesting an internal break or other failure.
步骤二：拆下启动器和保护器
压缩机的启动器和保护器是确保压缩机安全启动和运行的关键部件。它们通常连接在压缩机的侧面或顶部。我们要小心拆下这些部件以便进行检测：
- 测量结果：
- 启动器的阻抗测量结果为1.86兆欧，这意味着启动器已经开路，不再能正常工作。
- 保护器同样也显示开路状态，表明其内部断路或其他故障。
Step Three: Replace with New Parts
To rectify the situation, we must replace these faulty components. The new starter’s resistance is 20.7 ohms, which is within the normal range. The new overload resistance is around 1.4 ohms, also normal. After installing these new parts, we reconnect the power and check the current again. Now, the compressor shows a current of 1.27A, indicating it’s functioning correctly.
步骤三：更换新配件
为了解决问题，我们需要更换这些已经失效的部件。
- 新配件的阻抗：
- 新启动器的阻抗是20.7欧姆，这是一个正常的阻抗值，说明它可以正常工作。
- 新保护器的阻抗大约为1.4欧姆，这也在正常范围内。
更换后，我们小心地将新的启动器和保护器安装回压缩机，然后重新连接电源线，并用电流表再次检测电流。
- 结果：压缩机的电流此时显示为1.27A，这表明压缩机已经恢复正常工作。
Step Four: Temperature Measurement
To confirm the cooling has been restored, we use a temperature gun to measure the various parts of the compressor. The top of the compressor reads 49°C, the exhaust pipe at 51.8°C, and the filter at 44.4°C, all within normal operating ranges. Then, we take a small cup of water and observe its temperature starting dropping from room temperature to 21.9°C, signifying the cooling function has been restored.
步骤四：温度测量
为了确认制冷功能的恢复，我们使用了温度枪对压缩机的各部分进行了温度测量：
- 温度读数：
- 压缩机顶部温度：49°C
- 排气管温度：51.8°C
- 过滤器温度：44.4°C
所有这些温度都符合正常的操作范围，这是一个很好的迹象。接着，我们取了一小杯水，通过观察，发现水温从室温开始下降到了21.9°C，这表明冷水功能已经恢复。
Conclusion
Through careful inspection and replacement of the starter and overload, we’ve successfully addressed the cooling issue in the Mizusenmon water cooler dispenser. Remember, safety is paramount when performing any electrical or mechanical repairs; always ensure the power is disconnected to avoid potential hazards.
结论
经过细致的检查和替换启动器及保护器，我们成功地解决了Mizusenmon饮水机的制冷问题。请记住，在进行任何电气或机械维修时，安全第一，确保断开电源以避免任何潜在的危险。
