Cold and hot integrated water fountain utilizing air as heat transfer medium

Abstract

The invention discloses a cold and hot integrated water fountain utilizing air as a heat transfer medium. The cold and hot integrated water fountain comprises a water fountain shell, a water tank is arranged at the upper end of the water fountain shell, a hot water box and a cold water box are arranged in the water fountain shell and are both communicated with the water tank, the bottom end of the hot water box is provided with a hot water drain pipe, and the bottom end of the cold water box is provided with a cold water drain pipe. The water fountain is characterized in that heat exchangers are arranged in the hot water box and the cold water box respectively, an air compressor is installed in the water fountain shell, the portion, corresponding to an air inlet pipe of the air compressor, of the water fountain shell is provided with an air inlet, an outlet of the air compressor is connected to nozzles of vortex pipes, hot air pipes of the vortex pipes are connected with an inlet of the heat exchanger of the hot water box, and cold air pipes of the vortex pipes are connected with an inlet of the heat exchanger of the cold water box; the water fountain shell is further provided with an air exhaust pipe, and an outlet of the heat exchanger of the hot water box and an outlet of the heat exchanger of the cold water box are connected with the air exhaust pipe. The water fountain can supply cold water and hot water simultaneously and is simple in structure, small in size, low in energy consumption and environmentally friendly.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a water dispenser integrated with cooling and heating using air as a heat transfer medium. Background technique [0002] At present, domestic mainstream hot and cold water integrated water dispensers mostly use semiconductors and compressors for heating and cooling. [0003] The semiconductor direct-cooling hot and cold water dispenser provides normal temperature water from the water tank, and the water enters two ways, one way enters the cold tank and cools out cold water, and the other way enters the hot tank and heats out hot water. [0004] After the refrigeration switch is pressed, the AC voltage is stepped down by the power transformer, the rectifier diode is used for full-wave rectification, and the capacitor is filtered to output a DC voltage for cooling of semiconductor refrigeration components and fan exhaust. At the same time, the cooling indicator light is on. Since the direct c...

[0008] Semiconductor direct cooling hot and cold water dispenser has complex structure and high energy consumption

Compressor-type water dispensers need to add refrigerants. Most of the refrigerants currently used are greenhouse gases, and there is a lot of pressure on environmental protection.

[0009] In addition, many hot and cold water all-in-one machines on the market currently use the method of switching between hot and cold, and cannot provide cold water and hot water at the same time.
