Directly drinking machine with electronic refrigeration

Abstract

The invention relates to an instant drinking machine with electronic refrigeration. The instant drinking machine adopts raw water circulating cooling, and achieves continuous cooling effect through periodically discharging heated hot water after heat exchange and supplementing fresh low temperature raw water. The instant drinking machine comprises a front treatment device communicating with a water inlet port, and with a pressure pump, a reverse osmosis filter and a post filter via pipes; and an automatic flushing device communicating with a water outlet port and connected with the reverse osmosis filter, wherein a refrigerating device communicates with the front treatment device and the pressure pump, a water tank is arranged between the post filter and a purified water port, two drainage controllers are respectively arranged between the purified water port and the refrigerating device and between the purified water port and the water tank via three-way valves, an air cooling device is connected between the automatic flushing device and the reverse osmosis filter in series, two one-way valves with water flowing direction from a rear treatment device to the refrigerating device are respectively connected on the pipe between the front treatment device and the refrigerating device and on the pipe between the automatic flushing device and the air cooling device in series, and an electric control device is arranged in the machine.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a direct drinking machine with rapid cooling function, energy saving, sanitary belt and electronic refrigeration. Background technique [0002] The current direct drinking machines generally use compressors with refrigerants for refrigeration, which are bulky, occupy a large space, generate large noise, and pollute the environment. [0003] Another type of direct drinking machine adopts electronic refrigeration technology, which has the following deficiencies: [0004] 1. In terms of performance: the cooling water capacity is poor, far inferior to compression refrigeration, and it is difficult to meet people's daily needs for drinking cold water. [0005] 2. In terms of technology: the heat dissipation technology is backward, which leads to the long-term low-efficiency refrigeration condition of the semiconductor refrigeration chip. [0006] 3. Hygienic aspects: The gall cavity of th...
