Description

Drinking liquid refrigeration equipment

Technical Field

The invention belongs to the technical field of refrigeration, and particularly relates to drinking liquid refrigeration equipment.

Background

In the existing drinking equipment, cold water is provided mostly by adopting a semiconductor refrigeration mode, and the working principle of the refrigeration mode is as follows: after the semiconductor refrigeration chip is electrified, one surface of the semiconductor refrigeration chip heats (hot end) and the other surface refrigerates (cold end), and the drinking liquid is refrigerated through the cold end of the semiconductor refrigeration chip. The refrigeration mode has the advantages of no refrigerant, environmental protection, low noise, light weight, convenient installation, high production process and the like, and has the defect of low refrigeration capacity. The refrigerating capacity of the heat exchanger is affected by the characteristics of the chip, and is also seriously affected by cold end heat exchange and hot end heat dissipation performance. The outstanding problem is that the existing drinking equipment can not be cooled quickly, and a user needs to wait for a long time.

The semiconductor refrigeration technology is relatively widely and mature in application, but the technical problems cannot be effectively solved. In order to solve this technical problem, those skilled in the related art have conducted long-term research and assault. For example, chinese patent application publication No. CN1093456A discloses a portable semiconductor self-circulating cold drink machine which, in order to improve the cooling efficiency, allows cold drink to pass through a cold chamber inside a water storage tank, wherein the turbines (i.e., the inlet and outlet) of the cold pump are both mounted at the bottom of the water storage tank, and the outlet of the cold chamber is also located at the bottom of the water storage tank. Although the application date of the patent application of the invention is earlier, the technical improvement is relatively large, the practical use proves that the refrigerating efficiency of the cold drink machine is still not ideal, and a user only takes part of cold drink even when taking the cold drink, and the rest of the cold drink is taken out of normal-temperature or warm drinking liquid, so that the taste is very uncomfortable, and the user experience is difficult to achieve.

Although technicians in the field analyze factors causing low refrigeration efficiency of various semiconductor refrigeration and drinking equipment, a reasonable and scientific technical scheme cannot be effectively analyzed, so that the technical problem becomes one of technical bottlenecks in the field, and even some technicians abandon the advantages of the semiconductor chip refrigeration technology and cannot effectively overcome the defect of turning to other refrigeration technologies.
