实施例三， 本实施例中， 在对热水出水率进行未保温测试时， 当出水装置 4的出水量为 63KG, 每分钟约 4628.7G, 平均进水温度为 23.1 °C， 平均出水温度为 66.6°C， 其出水最高 温度为 68.5 °C， 可提高的热水出水率为 92.5% ; 当出水装置 4的出水量为 65.1KG, 每分钟 约 4628.7G, 平均进水温度为 23.rC， 平均出水温度为 65.6°C， 其出水最高温度为 68.6°C， 可提高的热水出水率为 93.1% ; 当出水装置 4的出水量为 62.74KG, 每分钟约 11865.6G, 平 均进水温度为 23°C， 平均出水温度为 67.8 °C， 其出水最高温度为 69.6°C， 可提高的热水出 水率为 92.4% ; 当出水装置 4 的出水量为 62.74KG, 每分钟约 5479.7G, 平均进水温度为 23°C， 平均出水温度为 67.8°C， 其出水最高温度为 69.5°C， 可提高的热水出水率为 92.6%。 其中， 所述出水量是从开始放水 15s 记录排水最高温度， 连续排水至比最高温度低 20 为 止， 其中进水温度对热水出水率影响不大。
根据以上四组测试的数据显示， 进出水装置 4结构适应大范围流量变化时， 也能提高热 水出水率， 另外， 其平均温度每升高 Γ ， 热水出水率提高 2%。
另外根据能效等级推算：
能效等级 24h固有能耗糸数 热水输出率
1 =<0.6 =>70
2 =<0.7 =>60
3 =<0.8 =>55
4 =<0.9 =>55
5 =<1.0 =>50 如果与 1级能效 =>70%比较， 热水出水率提高 22%以上。
以上所述仅是本发明的较佳实施方式， 故凡依本发明专利申请范围所述的构造、 特征及 原理所做的等效变化或修饰， 均包括于本发明专利申请范围内。
工业应用性
本发明创造的可提高热水出水率的储水式热水器， 包括水箱， 所述水箱中部设有发热装 置， 所述水箱的底部设有使冷水低速平稳进入水箱的进水装置， 所述水箱的顶部设有使热水 分区均匀流出的出水装置， 所述进水装置包括横向放置于所述水箱内的内进水管， 所述内进 水管连接有伸出所述水箱的外进水管， 所述内进水管开设有若干均匀分布的出水孔， 所述出 水装置包括横向放置于所述水箱内的内出水管， 所述内出水管连接有伸出所述水箱的外出水 管， 所述内出水管包括至少两个按区域均匀分布的吸水孔， 本发明通过外进水管使冷水进入 到内进水管内， 再通过若干均匀分布的出水孔， 使冷水以低速规则的方式平稳的进入到水箱 内， 水箱内的冷水被发热装置加热后， 热水内出水管通过至少两个按区域均匀分布的吸水 孔， 使热水以规则的方式均匀的流出外出水管， 这样水箱内的冷水和热水就不容易混合， 减 少热水流动距离， 进而使流出内出水管的热水出水率大大提高。 实用性强， 具有良好的市场 前景。
