本发明专利涉及一种饮水机，特别涉及一种采用半导体制冷片控制水温的饮水机。The patent of the present invention relates to a drinking water dispenser, in particular to a drinking water dispenser which uses a semiconductor refrigeration chip to control the water temperature.
背景技术Background technique
饮水机是一种与饮用水配合使用，可加热饮用水并方便人们饮用的装置。自问世以来，受到人们广泛的欢迎，很快在人们的日常生活中占据了不可替代的作用。在已有技术中饮水机都是设置两个供水开关，一个是供应加热过的饮用水，另一个是供应常温的饮用水，从而方便人们饮用。但是当人们想要喝到一定温度的水时，需要冷热水不断混合来调节水温，既不方便，也不能准确快速的调节水温，然而在一些应用场合中对水温有严格的要求，比如泡茶常需要95℃以上的热水、冲蜂蜜常需要 50℃~60℃的热水、泡咖啡常需要 80℃~90℃的热水、冲奶粉常需要 40℃~60℃的热水等，现有的饮水机不能满足这些要求；在炎热的夏天人们想要喝到室温以下的水也得不到满足。这种不足之处至今仍未得到解决。现有技术在给饮用水加热的过程中直接将电能转换成热能，这种方式对能量的利用率不高，在饮水机加热过程中会产生噪音。A water dispenser is a device that is used in conjunction with drinking water to heat drinking water and facilitate people to drink. Since its inception, it has been widely welcomed by people and soon played an irreplaceable role in people's daily life. In the prior art, the water dispenser is provided with two water supply switches, one is to supply heated drinking water, and the other is to supply normal temperature drinking water, thereby making things convenient for people to drink. However, when people want to drink water at a certain temperature, they need to constantly mix cold and hot water to adjust the water temperature, which is neither convenient nor accurate and fast. However, there are strict requirements on water temperature in some applications, such as soaking Tea often needs hot water above 95°C, honey often needs 50°C~60°C hot water, coffee often needs 80°C~90°C hot water, milk powder often needs 40°C~60°C hot water, etc. Existing water dispensers cannot meet these requirements; people want to drink water below room temperature in hot summer and cannot be satisfied. This deficiency has not been resolved to date. The prior art directly converts electrical energy into heat energy during the heating process of drinking water. This method does not have a high utilization rate of energy, and noise will be generated during the heating process of the water dispenser.
现有的饮水机主要有一些技术不足：不能方便的控制水温，不能满足用户的需要；难以将水温降到室温以下，也不能满足人们在夏天饮水的需求；同时，饮水机能量的利用率也不高，而且饮水机在使用过程中有噪音。Existing water dispensers mainly have some technical deficiencies: the water temperature cannot be conveniently controlled, and the needs of users cannot be met; Not high, and the water dispenser is noisy during use.

The power supply circuit is made of switching power supply. The 5V direct current is supplied to the microcontroller, and the 12V direct current is supplied to the semiconductor refrigerator and the valve through the electronic switch.
三个小水箱分别是冷水水箱、热水水箱和出水水箱；在实施例中小水箱采用 304食品级不锈钢做内胆，每个小水箱的容量为 300 毫升，当用户想要喝到的饮水温度与实际温度不同时，由于小水箱的容量小，可以快速升温或降温从而减少用户等待时间并且节能，降低水资源的浪费。当用户不需要饮用水时，饮水机待机，三个小水箱中可能残留不同温度的饮用水，由于设置了三个小水箱，所以冷水、热水和出水分开放置，减少了它们之间的热交换，可以达到较好的保温效果，进而能达到节能省电的效果，同时也减少了半导体制冷片的工作时间，延长了半导体制冷片的使用寿命，降低了整机的故障率和维修费用。The three small water tanks are cold water tank, hot water tank and outlet water tank respectively; in the embodiment, the small water tank adopts 304 food-grade stainless steel as the inner container, and the capacity of each small water tank is 300 milliliters. When the actual temperature is different, due to the small capacity of the small water tank, it can quickly heat up or cool down, thereby reducing the user's waiting time and saving energy, reducing the waste of water resources. When the user does not need drinking water, the water dispenser is on standby, and drinking water of different temperatures may remain in the three small water tanks. Since the three small water tanks are installed, the cold water, hot water and outlet water are placed separately, reducing the heat between them. Exchange can achieve a better heat preservation effect, and then can achieve the effect of energy saving and power saving, and also reduce the working time of the semiconductor cooling chip, prolong the service life of the semiconductor cooling chip, and reduce the failure rate and maintenance cost of the whole machine.

In most occasions, when using a semiconductor cooling chip, a fan or a heat sink is required to cool down, but in this application, one end of the semiconductor cooling chip is directly in contact with the cold water tank, and the other end is directly in close contact with the hot water tank, which reduces the volume of the whole machine. There is no need to use a fan or heat sink, which reduces the cost and energy consumption of the fan, avoids the noise caused by the fan during use, and avoids the damage of the semiconductor cooling chip due to excessive temperature, prolonging the service life. The direct contact between the semiconductor cooling sheet and the hot and cold water tank also reduces the thermal resistance, which makes the heat conduction between the semiconductor cooling sheet and the water tank more rapid and efficient, thereby reducing the heat between the semiconductor cooling sheet and other substances such as air in the surrounding environment. Exchange, more energy-saving and environmental protection; in the traditional hot water heating process, the hot water will vibrate and make sound, but in this application, because the cold water tank is in close contact with the semiconductor refrigerating sheet, the hot water tank is in close contact with the semiconductor refrigerating sheet, reducing the The vibration of the hot water reduces the sound.
温度传感器固定在小水箱内壁上；本实施例中温度传感器固定在小水箱内壁防止温度传感器随着水流运动，避免了温度传感器引线的松动以及脱落。The temperature sensor is fixed on the inner wall of the small water tank; in this embodiment, the temperature sensor is fixed on the inner wall of the small water tank to prevent the temperature sensor from moving with the water flow, and avoid the loosening and falling off of the lead wire of the temperature sensor.
