A heat exchange component of a healthy direct drinking water machine, a direct drinking water machine and a heat exchange method

Abstract

A heat exchange component for a healthy direct drinking machine comprises a hot water pipe and a cold water pipe, and also comprises a controller and a heat exchange box, wherein the hot water pipe and the cold water pipe are arranged in the heat exchange box, the heat exchange box is filled with a heat conduction agent, and a heating device and a temperature detection device are also arranged in the heat exchange box; the heating device performs heat treatment on the heat conduction agent in the heat exchange box by responding to a detection result of the temperature detection device. A direct drinking machine comprises a heating inner container, a water inlet pipe and a water outlet pipe; the water inlet pipe and the water outlet pipe are respectively communicated with the cold water pipe and a water outlet faucet; the direct drinking machine also comprises the heat exchange component for the healthy direct drinking machine, and the hot water pipe and the cold water pipe are respectively communicated with the water outlet pipe and the water inlet pipe. Compared with the prior art, the heat exchange component for the healthy direct drinking machine and the direct drinking machine have the advantages that a heat exchange dead zone in the heat exchange component can be eliminated, heat exchange is more sufficient, and sterilization is more thorough; because the heating device is arranged, the temperature of outlet water after heat exchange is more stable, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of drinking water machine components and heating, more specifically, it relates to a heat exchange component of a healthy direct drinking water machine, a direct drinking water machine and a heat exchange method. Background technique [0002] In crowded places such as schools, stations, etc., in order to meet people’s drinking water needs, direct drinking water dispensers are usually installed in these places. After the high-temperature tap water is cooled, it is exported to the outside of the direct water dispenser by the outlet pipe for people to drink. [0003] The cooling method of the existing direct water dispenser is mostly water cooling method, and in order to save energy and make full use of the heat in high-temperature tap water, the refrigerant of the water cooling method is usually tap water to be heated, on the one hand, the heat can be conducted to the tap water to be heated On the other hand,...

Problems solved by technology

Patent announcement number is the Chinese patent of CN104433798A, just proposed a kind of heat exchange mechanism that water dispenser is used, it is not difficult to find out from its technical scheme and accompanying drawing, this heat exchange mechanism has some drawbacks, at first, this heat exchange mechanism has some disadvantages. Heat exchange dead zone, that is, the area where the water flow does not flow, such as the water at both ends of the water chamber cannot circulate in time, especially at the lower end of the water temperature, it is easy to breed bacteria, which has a negative impact on the safety and quality of the drinking water; secondly, the current In the existing technology, the bacteria in the pipeline are often sterilized by high-temperature hot water, and for the bacteria gathered in the two ends of the water chamber, due to the dead zone of water flow, the hot water is difficult to reach, which reduces the disinfection effect; again, using The heat exchange scheme in the above-mentioned patent documents is greatly affected by the ambient temperature. For example, when the ambient temperature is very low, the temperature of the water in the water chamber will be very low, which will make the temperature of the hot water flowing out of the original warm water outlet one side Low, relatively, when the ambient temperature is high, the temperature of the water flowing out of the warm water outlet will be very high. The above situation affects the stability of the direct drinking water machine and reduces the water quality of the direct drinking water machine; finally, as far as industrial production is concerned, The heat exchange pipeline mechanism with coaxial centers is not easy to weld during production, and the production process is relatively complicated. Moreover, due to the direct cold and heat impact between the hot and cold water pipes, cracks are likely to occur at the welded part of the heat exchange pipeline due to thermal expansion and contraction. , have a certain impact on the safety and life of the drinking water dispenser
