Abstract

Provided is a drinking water dispenser structure using cold and hot loops to achieve temperature drop and afterheat warming, which includes a cooling device, a pump operatively connected to a drinking water switch, a heating device, a hot temperature-change guiding pipe and a water output control device. The cooling device includes a cold water pipe and a first heat exchange pipe arranged at an outer edge of the cooling device. The heating device includes a hot water pipe and a heating body arranged at the center of the heating device. The water output control device has a warm/hot switch capable of being set to a hot water mode or a warm water mode. Accordingly, when the drinking water switch is turned on, raw water connected to a water source is pressurized by the pump to flow through the cold water pipe and enter the hot water pipe, so that the raw water is instantaneously heated by the heating body to be hot water of 100 DEG C. When the warm/hot switch is set to the hot water mode, hot water flows out from a warm/hot water output pipe for being drunk by the user. When the warm/hot switch is set to the warm water mode, hot water flows through the hot temperature-change guiding pipe and enters the first heat exchange pipe, so that the hot water is cooled by the cold water in the cold water pipe to become warm water which then flows out from the warm/hot water output pipe for being drunk by the user. Because the present invention is capable of providing drinking water by heating raw water in real time, there is no need to have a water storage tank and its thermal insulation device. In addition, because the raw water is heated to become hot water of 100 DEG C and the warm water is generated by cooling the hot water, the user is guaranteed not to drink un-boiled drinking water. Furthermore, because the warm water is obtained by performing heat exchange between hot water and cold water and partial heat energy of the hot water is transferred to the cold water, the temperature of the cold water is increased and the cold water then flows into the hot water pipe for being heated, thereby achieving the effect of energy-saving.

Description

The structure of the water dispenser that uses the hot and cold loop to achieve cooling and residual heat heating

The invention relates to a water dispenser structure, in particular to a water dispenser structure which uses a hot and cold loop to achieve temperature reduction and residual heat heating.

If the water dispenser is provided with drinking water of different temperatures, such as temperature and heat, the structure is provided with a heating unit that boils raw water, a cooling unit that cools the hot water, a hot water tank that stores hot water, and a storage. a warm water warm water tank and a water temperature sensing unit for sensing heat preservation; the operation mode is that raw water is first boiled into hot water by a heating unit and then connected to a hot water tank for storage, and a part of the hot water is cooled by a cooling unit. After the warm water is connected to the warm water tank for storage, the water temperature sensing unit separately heats the hot water tank and the warm water tank; since the water storage tank needs to maintain the constant temperature, the water temperature sensing unit needs to be started frequently, so that The water consumption of the water dispenser is increased, and the internal setting of the hot water tank and the warm water tank is required to form a bulky space and occupying space.

Recently, in order to improve the lack of power consumption caused by the constant temperature of the water storage tank, the water dispenser industry has a water dispenser that is heated and boiled in an instant. The operation mode is that the raw water is pumped out of the water storage bucket from a pump and heated by a moment of heating. The device is boiled into hot water and then discharged from a water outlet; however, the water dispenser can only supply 100 °C hot water, and the user needs to add cold water to cool down before drinking, so this mode is very inconvenient. Some manufacturers also add a cooling unit that cools the hot water inside the instant boiling water dispenser. This method allows the user to conveniently drink warm water, but the cooling unit applies electric energy for cooling. From the perspective of energy use, the drinking machine first consumes electric energy to boil the raw water, and then consumes electric energy to cool the hot water. It seems that there is a double waste of energy.

In view of this, how to improve the power consumption of the water storage tank of the water dispenser and the huge space occupied by the water dispenser, and how to make the user safe and convenient to drink hot water and warm water have become the main subjects of the research and development of the inventor. .
