技术领域 本发明创造涉及一种通风降温设备， 特别是一种能有效调节空气 湿度、 降低气温的电扇。 背景技术 空气调节电扇区别于传统电风扇之处在于其增加了水冷降温的 结构， 有一定降温作用， 同时水分子的挥发增加了空气的湿度， 在空 气干燥的我国北方地区很受消费者欢迎。但现有空气调节电扇由于只 靠水冷降温， 降温效果并不理想，而且在降温的同时必然加大空气湿 度， 以致影响了该产品在空气湿度较大的南方地区的推广。 发明内容 TECHNICAL FIELD The present invention relates to a ventilation and cooling device, and in particular to an electric fan capable of effectively adjusting air humidity and reducing air temperature. BACKGROUND OF THE INVENTION The air-conditioning electric sector is different from the traditional electric fan in that it increases the structure of water cooling and cooling, and has a certain cooling effect. At the same time, the evaporation of water molecules increases the humidity of the air, which is very popular with consumers in the dry regions of northern China. However, because the existing air-conditioning fans only use water cooling to cool down, the cooling effect is not ideal, and the air humidity must be increased at the same time as the temperature is reduced, which has affected the promotion of the product in the southern regions with high air humidity. Summary of the Invention
本发明创造的目的在于克服现有技术的不足之处，提供一种降温 效果明显， 并能保持空气湿度不变的空气调节扇。  The purpose of the present invention is to overcome the shortcomings of the prior art and provide an air-conditioning fan that has a significant cooling effect and can maintain the same air humidity.
本发明创造的任务是这样实现的： 一种空气调节电扇， 由风轮 The task created by the present invention is achieved as follows: An air-conditioning electric fan
( 1 )、 出风口 （2)、 进风口 （3)、 水箱（4)、 水帘 （5) 组成， 水帘 设在进风口与风轮之间，其下段置于水箱内，其特征在于它还包括一 个放置在进风通道上的储冷器（6)，其内有多根装有蓄冷液的储冷管(1), the air outlet (2), the air inlet (3), the water tank (4), and the water curtain (5), the water curtain is located between the air inlet and the wind wheel, and the lower section is placed in the water tank, which is characterized by It also includes a cold accumulator (6) placed on the air inlet channel, which contains a plurality of cold storage tubes filled with cold storage liquid
(7)。 (7).
本发明创造结构合理， 降温效果明显，产品制造成本及使用成本 均较低， 由于在水冷基础上增加了储冷器的热交换降温， 因此本发明 创造降温效果更佳。而且， 当使用环境空气湿度较大， 不适宜再进行 水冷降温时， 本发明创造也可仅利用单一储冷器方式实现降温效果。 附图说明 The invention has reasonable creation structure, obvious cooling effect, low product manufacturing cost and use cost, and the heat exchange cooling of the cold accumulator is added on the basis of water cooling. Create better cooling effect. In addition, when the humidity of the ambient air is large and it is unsuitable to perform water cooling and cooling, the invention can also use only a single cooler to achieve the cooling effect.

5 水帘 6 储冷器  5 water curtain 6 cooler
7 储冷管 具体实施方式  7 Cold storage pipe
现有技术中的空气调节电扇主要靠水冷降温， 它由风轮（1 )、 出 风口 （2)、 进风口 （3)、 水箱（4)、 水帘 （5 ) 组成， 水帘的下段置 于水箱内， 吸满水分的水帘置于进风口与风轮之间，外界空气进入电 扇箱体后经过水帘过滤， 再经由出风口排出， 从而实现通风降温。  The air-conditioning electric fan in the prior art is mainly cooled by water. It is composed of a wind wheel (1), an air outlet (2), an air inlet (3), a water tank (4), and a water curtain (5). In the water tank, a water curtain filled with moisture is placed between the air inlet and the wind wheel. After the outside air enters the fan box, it is filtered by the water curtain and then discharged through the air outlet to achieve ventilation and cooling.
为增强降温效果， 可在进风通道上设置储冷器（6)， 储冷器是多 根储冷管 （7) 的集合体， 储冷管可由热传导较好的金属材料制成， 其内装有蓄冷液。储冷器可设置在电扇箱体内，位于进风口与风轮之 间的风道上， 其优点是储冷器封闭在箱体内， 只吸收箱体内的热量， 降温效果较好。 使用时先将储冷器经过物理降温（例如放在冰箱内） 至室温以下 （温度越低效果越明显)， 然后再放入电扇箱体内相应位 置。 当储冷管温度与室温大致相当时， 热交换趋于停止， 降温效果不 再明显， 此时可再把储冷器取出重新进行物理降温， 重复以上步骤， 达到降温效果。 In order to enhance the cooling effect, a cold accumulator (6) may be provided on the air inlet channel. The cold accumulator is an assembly of multiple cold accumulating tubes (7). The cold accumulating tubes may be made of a metal material with good heat conduction, There is cold storage fluid. The cold accumulator can be installed in the electric fan box and located on the air duct between the air inlet and the wind wheel. The advantage is that the cold accumulator is enclosed in the box and only absorbs the heat in the box, which has a better cooling effect. Physically cool the cooler before use (eg in a refrigerator) The temperature is lower than the room temperature (the lower the temperature, the more obvious the effect is), and then put it into the corresponding position inside the fan box. When the temperature of the cold storage tube is approximately equal to the room temperature, the heat exchange tends to stop, and the cooling effect is no longer obvious. At this time, the cold storage can be taken out again to perform physical cooling, and the above steps are repeated to achieve the cooling effect.
本发明创造还有另一实施例。为方便取放，储冷器也可设置在电 扇箱体外进风口处， 空气在被吸入箱体前先经过储冷器进行热交换， 从而达到降温目的。  The invention also has another embodiment. For easy access, the cooler can also be set at the air inlet outside the fan box. The air is first exchanged through the cooler before being sucked into the box to achieve the purpose of cooling.
